System Requirements

Server and client requirements

Low client and server base requirements are core features that keep Foswiki widely deployable, particularly across a range of browser platforms and versions. Many extensions exist which enhance and expand Foswiki's capabilities; they may have additional requirements.

Server Requirements

The code is written in Perl 5, and uses a number of shell commands from perl. The default package requires RCS (Revision Control System), a GNU Free Software package. Foswiki is developed in a basic Linux/Apache environment. It also works with Microsoft Windows, and should have no problem on any other platform that meets the requirements.

Resource Required Server Environment *
Perl 5.6.1 or higher (5.8.4 or higher is recommended)
RCS 5.7 or higher (including GNU diff)
Optional, Foswiki includes a pure perl implementation of RCS that can be used instead (although it's slower)
GNU diff GNU diff 2.7 or higher is required when not using the all-Perl RcsLite.
Install on PATH if not included with RCS (check version with diff -v)
Must be the version used by RCS, to avoid problems with binary attachments - RCS may have hard-coded path to diff
GNU patch For upgrades only: GNU patch is required when patching the code using patches in diff format submitted by the community.
GNU fgrep, egrep Modify command line parameters in configure if you use non-GNU grep programs
Cron/scheduler • Unix: cron
• Windows: cron equivalents
Web server Apache is well supported; see Foswiki:Support.InstallingOnSpecificPlatforms for alternative options.

Perl Modules

A complete list of the required and optional Perl modules can be found in lib/DEPENDENCIES.

Most of them will probably already be available in your installation. You can check version numbers with the configure script, or if you're still trying to get to that point, check from the command line like this:

perl -e 'use FileHandle; print $FileHandle::VERSION."\n"'

Client Requirements

The standard installation has relatively low browser requirements:

  • HTML 4 compliant
  • Cookies, if persistent sessions are required

CSS and Javascript are used in most skins. Some skins will require more recent releases of browsers. The default skin is tested on IE 6, 7, Safari 3.0, and recent Mozilla based browsers (such as Firefox).

You can easily select a balance of browser capability versus look and feel. Try the installed skins at SkinBrowser and more at Foswiki:Extensions.SkinPackage.

Important note about Plugins

  • Plugins can require just about anything - browser-specific functions, stylesheets (CSS), Java applets, cookies, specific Perl modules,... - check the individual Plugin specs.

Installation Guide

This guide describes the steps for manually installing Foswiki, with specific steps for installations on Linux with the Apache web server. If you are using a different web server or operating system, in addition to reviewing this document, check any additional information specific to your platform at Foswiki:Support.SupplementalDocuments. Foswiki:Support.SupplementalDocuments also has information for other scenarios, such as shared web hosting environments.

These installation instructions are also available online at Foswiki:System.InstallationGuide, and are available within your Foswiki installation at System.InstallationGuide (the InstallationGuide topic in the System web).

For information on upgrades, please also refer to Foswiki:System.UpgradeGuide. A static HTML version of this document, UpgradeGuide.html, is included in the root of your Foswiki distribution.

System Requirements

Please see the section "Foswiki system requirements" for the server and client requirements to run Foswiki, including the Perl modules required on the server. If you need to install any Perl libraries from CPAN for use by Foswiki, see Foswiki:Support.HowToInstallCpanModules for more information.

Preparing to install

Before attempting to install Foswiki, you are encouraged to review the Foswiki:System.AdminSkillsAssumptions. This guide assumes the person installing Foswiki has a basic knowledge of server administration on the system on which Foswiki is to be installed. While it is possible to install Foswiki with FTP access alone (for example, on a hosted site), it is tricky and may require additional support from your hosting service (for example, in setting file ownership and installing missing perl CPAN libraries).

If you are upgrading from a previous Foswiki version or from a TWiki installation, please refer to Foswiki:System.UpgradeGuide. A static HTML version of this document, UpgradeGuide.html, is included in the root of your Foswiki distribution.

Verify that your server meets the Foswiki system requirements, including having the minimum required Perl version and all required Perl modules installed. If you need to install any Perl libraries from CPAN for use by Foswiki, see Foswiki:Support.HowToInstallCpanModules for more information.

If you need help, feel free to ask a question in the Foswiki:Support web or on Foswiki:Community.InternetRelayChat (irc.freenode.net, channel #foswiki).

Basic installation: getting Foswiki up and running

To install Foswiki, complete the following steps:

  1. Download and unpack the Foswiki distribution.
  2. Set the file and directory permissions for the installation.
  3. Configure the locations of the Perl executable and the Foswiki modules.
  4. Configure the web server.
  5. Configure Foswiki.
  6. Enable authentication of users (if desired).
  7. Define the administrator users.

Download and unpack the Foswiki distribution

Download the Foswiki distribution from http://foswiki.org/Download

Unpack the distribution file: Change to the directory where you want to place the Foswiki directory. Unzip or untar and gunzip the distribution; a new subdirectory called Foswiki-VERSION will be created. You can rename this subdirectory to a shorter name. For the rest of this document, this subdirectory is assumed to be at /path/to/foswiki.

  • Note: Foswiki does not support directory paths that contain spaces, so ensure that all of its directory paths do not contain any spaces (particularly on Windows).

If you do not have shell access to your web server host, see the section "Uploading the Foswiki distribution to your web server host".

Set the file and directory permissions for the installation

Set up access file and directory rights, as well as file ownership, as required by your web server configuration so that the web server user (the user used by the web server to run CGI programs) can read and write within the foswiki directory tree.

Note: for more information on the appropriate permissions to ensure security for your Foswiki data, see Foswiki:Support.SecuringYourSite.

The default file and directory access permissions as set by the distribution define a reasonable security level that will work for many types of installations, including shared hosting. Nonetheless, you should verify that the web server user has read access to all files and directories beneath the foswiki directory, and execute access for all directories. Also verify that the data and pub directories and all the subdirectories and files beneath them allow write access for the web server user.

  • Warning: Do not just run a chmod -R 770 foswiki. Providing execute access to all files is potentially dangerous. This is a common mistake made by Foswiki installers. See Foswiki:Support.SettingFileAccessRightsLinuxUnix for a sample set of Unix commands to set the file and directory permissions.

It is possible to define tighter access permissions than the default ones; how tight they should be depends on your web server environment and local needs. Typically you should limit all access from others if the web server machine has login access for users other than root and the web server administrator. For a dedicated web server that just runs Foswiki and has limited login access, the default access permissions have a good safety level.

If you have root user permissions, then for additional security, you can change the ownership of the foswiki directory tree to the web server user, using the command chown -R user:group /path/to/foswiki. The web server username varies in different installations; here are some sample commands for various Linux distributions:

  • RedHat, Fedora, CentOS, Gentoo, Mandriva : chown -R apache:apache /path/to/foswiki
  • debian/Ubuntu/Kubuntu : chown -R www-data:www-data /path/to/foswiki
  • Suse : chown -R wwwrun:www /path/to/foswiki

If Foswiki stops working after you applied a change in access permissions and you wish to restore the original permissions, run the Unix commands located at Foswiki:Support.SettingFileAccessRightsLinuxUnix.

Configure the locations of the Perl executable and the Foswiki modules

Make sure the Foswiki scripts can be executed by the web server. The default location of Perl is /usr/bin/perl. If it's somewhere else, change the path to Perl in the first line of each script (you may have to give yourself write permission first) in the bin and tools directories. You can use the tools/rewriteshbang.pl script to do this; for example:

   cd /path/to/foswiki/bin
   /path/to/perl ../tools/rewriteshbang.pl
   # At the prompt, enter the full path to the perl executable, including
   # the full filename of the executable. You will be prompted twice for
   # this information in order to confirm it.
   cd /path/to/foswiki/tools
   /path/to/perl rewriteshbang.pl

Some web servers require a special extension on perl script files (e.g. .cgi or .pl). This is not normally required with the Apache web server, though some hosted web servers are configured to require it. If the documentation for your web server indicates that a special extension is necessary, rename all the executable scripts in bin; that is, rename bin/view to bin/view.pl, and so on. When configuring Foswiki (see the section "Configure Foswiki"), set the ScriptSuffix option to the special extension.

Create the file LocalLib.cfg located at bin/LocalLib.cfg

  • In the bin directory, copy the template file LocalLib.cfg.txt to LocalLib.cfg. Make sure the ownership and access rights of the copy are the same as LocalLib.cfg.txt.
  • Edit bin/LocalLib.cfg so that $foswikiLibPath is set to the absolute file path of your lib directory. For example: /path/to/foswiki/lib.
  • If you need to install additional CPAN modules, but can't update the main Perl installation files on the server, you can set $CPANBASE to point to your personal CPAN install. Don't forget that the web server user has to be able to read those files as well.

Configure the web server

First choose the best configuration method for your web server. With Apache, there are two ways to configure it: a config file included from httpd.conf or .htaccess files.

  • Apache config file: The recommended method is using a config file. With a config file you can put the entire Foswiki configuration in ONE file (typically named foswiki.conf). Performance is much better with a config file, and one file gives the best overview and ensures that you get a safe installation . However to use a config file you need root or sudo access to stop and start Apache. The Foswiki apache config file is included from the main Apache config file http.conf. Most distributions have a directory from which any file that ends with .conf gets included when you restart Apache (Example RedHat/Fedora/Centos: /etc/httpd/conf.d ). If you use a virtual host setup in Apache you should include the foswiki.conf file from inside the desired virtual host config in your Apache configuration.
  • .htaccess files: This method should only be used when you cannot use a config file. Performance is slower as Apache must search through all applicable directories for any .htaccess files on each page access. Normally this is the only way to control Apache in a shared host environment where you have no root or sudo privileges.

If you are using a config file:

  • The easiest and best way is to use the Foswiki:Support.ApacheConfigGenerator tool to generate a safe, working config file for your Foswiki installation, based on the options you choose in the tool.
  • If you can't use the online configuration generator, a sample config file called foswiki_httpd_conf.txt can be found in the root of the foswiki installation.
  • Ensure that web access is denied to all Foswiki subdirectories other than bin and pub. The Foswiki:Support.ApacheConfigGenerator tool will generate the appropriate settings; the foswiki_httpd_conf.txt file also has examples of configuring Apache appropriately.
  • Ensure there is either a ScriptAlias directive for the bin subdirectory, or an Alias directive with SetHandler cgi-script and Options ExecCGI directives for the bin subdirectory, so that the bin scripts will be executed by Apache.
  • Note: you must restart Apache after making changes to your config files for the changes to take effect.

If you are using a .htaccess file:

  • In the root of the foswiki installation and in the bin directory, there are sample .htaccess files for various subdirectories in your installation. Each file has help text explaining how to modify it for your configuration. For more information, see Foswiki:Support.SupplementalDocuments.
    location and name of sample .htaccess file copy sample file to the following location
    foswiki/root-htaccess.txt foswiki/.htaccess
    foswiki/bin/.htaccess.txt foswiki/bin/.htaccess
    foswiki/pub-htaccess.txt foswiki/pub/.htaccess
    foswiki/subdir-htaccess.txt .htaccess in all other subdirectories below foswiki
  • Ensure that web access is denied to all Foswiki subdirectories other than bin and pub. The sample .htaccess files show how to configure Apache appropriately.
  • Ensure that the foswiki/bin/.htaccess files contains the line SetHandler cgi-script so that all scripts in the bin directory will be executed by Apache.

Turn off any kind of PHP, Perl, Python, Server Side Includes, or other software execution mechanisms supported by your web server in the pub directory. For example, most Linux distributions have a default Apache installation with PHP and server side include (SSI) enabled. This would allow PHP scripts uploaded as attachments to be executed, which is a security risk, so it should be disabled in the Apache configuration with php_admin_flag engine off.

Different script execution mechanisms are disabled in different ways; see your web server configuration and documentation for more details.

Protect the configure script: You should never leave the configure script open to the public. Limit access to the bin/configure script to either localhost, an IP address or a specific user using basic Apache authentication. The Foswiki:Support.ApacheConfigGenerator lets you setup who has access to the configure script. Also see the foswiki-httpd-conf.txt or bin/.htaccess.txt file for an example of the setting required to protect the configure script.

To limit access to a particular user, set up a .htpasswd file that contains the user name and password that Apache will use to authenticate the user:

  • Change to the foswiki/data directory.
  • Issue the command htpasswd -c .htpasswd <username>, where <username> is the name of the user you will use to access the configure script. Choose the username with care: the username cannot be an existing login name for your Foswiki installation, nor can it be used later on to register in Foswiki. Enter a password when prompted.

The Foswiki:Support.ApacheConfigGenerator tool and the sample config files and .htaccess files show how to configure Apache so that the configure web page will be protected using the user and password held in the data/.htpasswd file. The Apache config file or .htaccess file will have a Require user <username> directive to restrict access to the configure script. Ensure the user specified in the directive matches the <username> you used when creating the .htpasswd file.

Note: In addition to any web server security protection that you have set up, when saving any configuration settings for the first time on the configure web page, you will be prompted to set a configuration password. This password must be entered on all subsequent configuration changes, and is also used to log in via the internal admin link (see the section "Define the administrator user(s)"). Even after a configure password has been set, access to the configure page should still be restricted by the web server, in order to avoid revealing internal information to potential attackers.

For more information, refer to Foswiki:Support.ProtectingYourConfiguration.

Configure Foswiki

Run the configure script from your browser: enter http://yourdomain/foswiki/bin/configure into your browser address bar.

  • When you access the configure web page for the first time, you can only edit the section General Path Settings. Make any required changes, and save the settings, whether or not you needed to make any changes. You will be prompted to set a password for the configure page: this password must be entered for all subsequent configuration changes, and is also used to log in via the internal admin link (see the section "Define the administrator user(s)"). Note the configuration password is separate from any web server security you have set up for the configure web page (see "Protect the configure script").
  • Continue configuring Foswiki. Resolve any errors or warnings highlighted on the configure page.
  • If your web server can be accessed by more than one domain name make sure to add the additional alternative URLs to {PermittedRedirectHostUrls}
  • Setup the Mail and Proxies section. The {WebMasterEmail} and {SMTP}{MAILHOST} settings must be defined so Foswiki can send registration emails. Many ISPs have introduced authentication when sending emails to fight spam so you may also have to set {SMTP}{Username} and {SMTP}{Password}. If you do not want to enable sending registration emails or want to enable it later you can uncheck {EnableEmail}. If your server is behind a firewall with a proxy, and you wish to install extensions via configure, you may have to set {PROXY}{HOST} and {PROXY}{PORT}.

If there is a problem with your setup that prevents you from accessing the configure page, you can configure Foswiki manually.

Enable authentication of users

By enabling authentication, you can control access to your site and track the activity of your users. This is particularly important for sites that are publicly accessible on the web. You are strongly encouraged to read System.UserAuthentication and Foswiki:Support.UserAuthenticationSupplement for further information about managing users and access controls for your Foswiki site.

The most common authentication methods used for public Foswiki installations are Template Login and Apache Login. They have the following relative advantages:

  • Template Login can be set up without any web server configuration, and users can log off without restarting the browser. As the login page is just a Wiki page, you can customize it to suit your needs.
  • Apache Login allows you to use any Apache-module based authentication scheme, such as mod_auth_ldap or mod_auth_mysql. However, as your browser is caching your login, you must restart the browser to log out.

Note that the password databases for both of these authentication mechanisms are compatible, so you can switch between them at a later date.

To make it easier to follow the instructions in this section, you can view this installation guide using your Foswiki site by entering System.InstallationGuide into the "Jump" text box. By doing this instead of using the INSTALL.html file from the distribution, you will be able to use the embedded hyperlinks to jump directly to the referenced pages.

Template Login authentication

With Template Login enabled, when Foswiki needs to authenticate the user, it will redirect to a login web page. A list of all users is shown in the Main.WikiUsers topic.

To setup Template Login, perform the following steps:

  1. Configure Template Login. Under the Security Settings pane of the configure page:
    1. Select Foswiki::LoginManager::TemplateLogin for {LoginManager}.
    2. Select Foswiki::Users::HtPasswdUser for {PasswordManager}.
    3. Select Foswiki::Users::TopicUserMapping for {UserMappingManager}.
    4. Save your settings.
  2. Verify that registration works. Register yourself using the System.UserRegistration topic in your Foswiki installation. Note if you are viewing this page via the INSTALL.html file, then you can access the user registration page by entering System.UserRegistration into the "Jump" text box at the top right of any Foswiki page in your installation.
    Check that the password manager recognizes the new user by verifying that a new line is added to the foswiki/data/.htpassswd file, with the username and encrypted password. If the user and password information was not added, you probably got a path wrong, or the directory permissions on foswiki/data or foswiki/data/.htpasswd may not be set to allow the web server user to modify the file.
  3. Check that authentication works. Edit a topic by clicking on the Edit link at the top or bottom of a topic. If you have been authenticated, then you will see the edit page; otherwise, you will see an error message.

As Template Login uses a wiki page for its login prompt, there is a great deal of flexibility in customizing the login page for your purposes.

Apache Login authentication

With Apache Login enabled, when Foswiki needs to authenticate the user, the standard HTTP authentication mechanism is used: the browser itself will prompt for a user name and password.

Note: Apache Login is required for Apache-based login methods such as mod_ldap.

To setup Apache Login, perform the following steps:

  1. Configure Apache Login. Under the Security Settings pane of the configure page:
    1. Select Foswiki::LoginManager::ApacheLogin for {LoginManager}.
    2. Select Foswiki::Users::HtPasswdUser for {PasswordManager}.
    3. Select Foswiki::Users::TopicUserMapping for {UserMappingManager}.
    4. Save your settings.
    5. Configure your Apache settings for HTTP authentication. Use the Foswiki:Support.ApacheConfigGenerator tool or the foswiki/bin/.htaccess file to set the following Apache directives on the bin scripts:
            <FilesMatch "(attach|edit|manage|rename|save|upload|mail|logon|rest|.*auth).*">
            require valid-user
            </FilesMatch>
      You can also refer to the sample foswiki_httpd_conf.txt and bin/.htaccess.txt files to see how the appropriate Apache directives are specified.
  2. Verify that registration works. Register yourself using the System.UserRegistration topic in your Foswiki installation. Note if you are viewing this page via the INSTALL.html file, then you can access the user registration page by entering System.UserRegistration into the "Jump" text box at the top right of any Foswiki page in your installation.
    Check that the password manager recognizes the new user by verifying that a new line is added to the foswiki/data/.htpassswd file, with the username and encrypted password. If the user and password information was not added, you probably got a path wrong, or the directory permissions on foswiki/data or foswiki/data/.htpasswd may not be set to allow the web server user to modify the file.
  3. Check that authentication works. Edit a topic by clicking on the Edit link at the top or bottom of a topic. If you have been authenticated, then you will see the edit page; otherwise, you will see an error message.

Choose search algorithm based on your platform

Under Store Settings in configure you will find the setting {RCS}{SearchAlgorithm}.

By default it is set to Foswiki::Store::SearchAlgorithms::Forking which is what you should keep if you install Foswiki in Linux or any other Unix type operating system.

If you install Foswiki on a Windows server, using an external grep program can create problems because of limitations in the length of command lines. You may be able to run with Forking in Windows if your directory path to Foswiki is kept short (short directory names and few levels). The safe setting for Windows is Foswiki::Store::SearchAlgorithms::PurePerl.

Define the administrator user(s)

Administrators have read and write access to any topic, regardless of any access controls that have been applied to the topic or its web. After installing Foswiki, you should register a user that you will use to administer Foswiki. To make this user an administrator, add the WikiName for the user to the AdminGroup, defined in the Main.AdminGroup topic in your Foswiki installation.

To make it easier to follow the instructions in this section, you can view this installation guide using your Foswiki site by entering System.InstallationGuide into the "Jump" text box. By doing this instead of using the INSTALL.html file from the distribution, you will be able to use the embedded hyperlinks to jump directly to the referenced pages.

To add an initial administrator to the AdminGroup, perform the following steps:

  • If you are not already logged in with your WikiName, then login.
  • Go to the Main.AdminGroup topic and select the "internal admin login" link. Login using the password you set on the configure page.
  • After logging as the internal admin, edit the Main.AdminGroup topic. Follow the instructions on the page carefully and add your WikiName to the group.
  • Test that you have been added successfully: On the Main.AdminGroup page, select the "Logout link" and logout from being the internal admin. Select the "Edit" link for the Main.AdminGroup page. If you successfully added yourself as an admin user, you should see the edit page.

Once the AdminGroup is no longer empty, then any member of the group can add subsequent members — you do not have to use the internal admin login.

To more easily debug access control issues, you may want to have a regular Foswiki user account for daily use, and a special one that belongs to the AdminGroup that you use only for administering your Foswiki site. See Foswiki:System.AccessControl for more information on access controls and user groups.

Congratulations!

You now have a basic installation running. At this point you can just point your Web browser at http://yourdomain.com/foswiki/bin/view and start using your Foswiki site.

In order to keep your user, group, and site configuration information separate from the actual content of your site, it is recommended that you create a new web in which your site's pages will reside. See Foswiki:System.ManagingWebs for more information on Wiki webs and how to create one.

Beyond the basic installation

Once you have Foswiki installed and running, you can perform one or more of the following steps to tailor your installation to your needs. Many of the references in this section refer to topics within your Foswiki installation. For example, System.Skins refers to the Skins topic in your System web. To go directly to a topic, enter the full topic name, such as System.Skins, into the "Jump" text box at the top right of any Foswiki page.

To make it easier to follow the instructions in this section, you can view this installation guide using your Foswiki site by entering System.InstallationGuide into the "Jump" text box. By doing this instead of using the INSTALL.html file from the distribution, you will be able to use the embedded hyperlinks to jump directly to the referenced pages.

All of the Foswiki documentation can also be found online in the Foswiki documentation section (the "System" web) of the Foswiki web site.

Note the configure page mentioned in this section is accessed by visiting http://yourdomain/foswiki/bin/configure your web browser.

Site configuration and maintenance

Set Foswiki Preferences

Preferences for customizing many aspects of Foswiki are set by editing Main.SitePreferences. If a given preference is not set in Main.SitePreferences, then a default value is picked up from System.DefaultPreferences, if present, or, for extensions, from the extension topics.

To simplify your upgrades, do not modify System.DefaultPreferences. Instead, copy any settings you want to change from System.DefaultPreferences to Main.SitePreferences.

To see the available preferences that can be set, look through System.DefaultPreferences.

If, for some reason, you wish to pick up default preferences from a different topic, you can set the location in the Miscellaneous settings pane of the configure page, in the {SitePrefsTopicName} setting (visible when Expert mode is enabled). It is recommended that you leave this setting to its default value, DefaultPreferences.

Select the desired security level

Foswiki has a many security features that can be enabled/disabled and adjusted to suit your needs.

In many cases enabling a security feature prevents other features. It is a balance that the administrator has to choose depending on the purpose of the Foswiki installation (confidential vs public knowledge), the type of installation (intranet vs internet), and your type of business.

A new administrator is encouraged to read Foswiki:Support.SecurityFeatures which gives a walkthrough of the different security aspects and how to set the appropriate configuration settings. Note that that some security settings are only visible in configure in "expert mode" which you enter by clicking the "Yes, I've read all the documentation" button at the top of the configure screen.

Enable Email Notification

Each web has an automatic email notification service that sends you an email with links to all of the topics modified since the last alert. To enable this service:

  1. Confirm the Mail and Proxies settings on the configure page.
  2. Setup a cron job (or equivalent) to call the tools/mailnotify script, as described in the System.MailerContrib topic.

Automate removal of expired sessions and lease files

By default Foswiki cleans out expired session and lease files each time any topic is viewed, but this has a performance cost. Instead you may wish to schedule a cron job (or equivalent) to run the tools/tick_foswiki.pl script, and set a negative value on the configure page for {Sessions}{ExpireAfter}. For more details, read System.CommandAndCGIScripts#tick_foswiki_pl.

Enable WebStatistics

You can manually or automatically generate a listing of the most popular pages for each web, based on number of visits. For information on setting up this feature, see the System.SiteTools topic.

Enable Localisation

Foswiki supports displaying national (non-ASCII) characters, and using different languages for its basic interface elements. To configure localisation, modify the Localisation section of the configure page. For more information, see Foswiki:Support.InternationalizationSupplement.

Customizing your site

Customize pages for managing personal information

If you are not using Foswiki to manage your users' passwords or email addresses, or would just like to enhance the default pages, then modify the following topics accordingly with information appropriate for your site:

Customize the user topic for new users

When a new user registers on your Foswiki site, a topic with a name corresponding to the user's WikiName is created in the Main web: this topic is the user's user topic. The user topic is based on the Main.NewUserTemplate? topic; if it is not present, then System.NewUserTemplate (and its associated System.UserForm) is used as a default. If you want to customize the user topic for your users, copy System.NewUserTemplate to Main.NewUserTemplate?, and System.UserForm to Main.UserForm?, and make your changes to Main.NewUserTemplate? and Main.UserForm?. (See Foswiki:System.ManagingTopics#CopyTopic for instructions on copying a topic.)

You can edit these topics to suit your needs, such as the following:

  • Customize the user topic for your site.
  • Add an ALLOWTOPICCHANGE preference setting to Main.NewUserTemplate? so only the user can edit their own user topic. In particular, on a public Foswiki site, restricting edit access will avoid vandalism and spam.
  • Add and remove fields defined in the Main.UserForm?.

If you added or removed fields from the user form you may also need to tailor Main.UserRegistration? to match (copy over the contents from System.UserRegistration to Main.UserRegistration when creating it).

Customize the appearance of your Foswiki site

The real power of Foswiki lies in its flexibility to be customized to meet your needs. To change the look of the default skin, PatternSkin, please refer to System.PatternSkin and System.PatternSkinCustomization.

At the Foswiki website you can find more resources. A good place to start exploring is the Foswiki:Support.AdministratorsCookBook which offers tips and tricks for customizing your Foswiki site. Many of these are best done before any content has been added to your site, so immediately after installation is a good time to consider the possibilities.

Left, Top and Bottom Bars with PatternSkin

The top bar and bottom bar are common across all webs.

To customize the top bar, copy System.WebTopBarExample to System.WebTopBar?, and make your desired changes to System.WebTopBar.

To customize the bottom bar, copy System.WebBottomBarExample to System.WebBottomBar?, and make your desired changes to System.WebBottomBar.

The side bar can be customized on a per web basis. To customize the side bar, copy the WebLeftBarExample topic in the given web to WebLeftBar, and make your desired changes to WebLeftBar. If you would like to move the side bar to the right of the page, see System.PatternSkin for more details.

Copyright, License and Classification Statements

At the bottom of each topic, there is a copyright statement that is set in the WEBCOPYRIGHT preference. Its default is the following: Copyright © by the contributing authors. All material on this collaboration platform is the property of the contributing authors.

If your Foswiki site is used in an environment without public access you should replace this with your normal copyright notice. You should also consider adding a security classification (e.g., For Internal Use Only) so people do not have to add this manually to every new topic.

If your Foswiki site is publicly accessible, you need to decide which copyright and license you wish to apply to all contributions. For open source applications, licenses such as the GNU Free Documentation License, FreeBSD Documentation License, and one of the various Creative Commons licenses are possible licenses to consider. Remember that once people have started contributing, you cannot retroactively change the license (unless it has a provision for this).

To change the copyright statement, perform the following steps:

  • Copy the WEBCOPYRIGHT preference setting from System.DefaultPreferences to Main.SitePreferences. Change the value to your desired text. This value will be your new default across all webs.
  • You can create a unique message for a specific web by setting the WEBCOPYRIGHT preference in the WebPreferences topic for the given web. For example, you could add a confidential classification to a web that has restricted access.
  • The WEBCOPYRIGHT preference setting in System.WebPreferences covers the documentation that comes with Foswiki, and should not be changed.

WYSIWYG vs Raw Edit

In Foswiki, the WYSIWYG editor is used by default in edit mode. An Edit Raw link is available for those who prefer to edit the raw topic text.

If you prefer to use the raw text editor by default and have a separate WYSIWYG button, as in TWiki 4.1, then you can modify the templates that define the edit screen as described in Foswiki:Support.FaqHowToMakeRawEditDefault.

Installing extensions

Foswiki:Extensions is an extensive library of plugins for Foswiki that enhance functionality in a huge number of ways. A few plugins are pre-installed in the Foswiki distribution.

In the Extensions section of the configure page, you can select the Find More Extensions button to download and install additional plugins from the foswiki.org website. If you are behind a firewall or your server has no access to the Internet, you can also install plugins manually. Installation instructions for each plugin are located in its corresponding topic on http://foswiki.org/. Additional documentation on Foswiki plugins can be found at Foswiki:Support.PluginsSupplement.

Plugins are activated in the Plugins section of the configure page. In addition, some plugins are also configured in this section.

TWiki Compatibility

Foswiki is 100% backwards compatible with TWiki® markup up to and including TWiki 4.2.4. Existing TWiki webs, topics and attachments can be used with Foswiki without requiring any changes.

To support a seamless upgrade from TWiki, Foswiki ships with a plugin called TWikiCompatibilityPlugin. This plugin enables most TWiki extensions to work with Foswiki, without modifications. It also maps requests for legacy TWiki web topics to their Foswiki equivalents, as defined in Foswiki:Development.TopicNameMappingTable. The TWIKIWEB and MAINWEB TWiki variables are also mapped to the new Foswiki macros SYSTEMWEB and USERSWEB.

If you are not upgrading an existing TWiki installation and do not plan to install plugins from the TWiki web site, it is recommended that you disable the TWikiCompatibilityPlugin in the Plugins Section on the configure page.

If a plugin exists both in a TWiki version and a Foswiki version, it is strongly recommended that you use the Foswiki version, as this is coded to work optimally with Foswiki. As part of the Foswiki project, the Foswiki community is evaluating all of the extensions that are available for TWiki, and porting them over to the Foswiki name space. Many of them are being enhanced through the removal of bugs and security vulnerabilities, resulting in better, more functional extensions for Foswiki.

Troubleshooting

Re-run the configure script and make sure you have resolved all errors and are satisfied that you understand any warnings.

Failing that, consult the topics at Foswiki:Support.SupplementalDocuments and Foswiki:Support.AskedQuestions.

If you need help, ask a question in the Foswiki:Support web or on Foswiki:Community.InternetRelayChat (irc.freenode.net, channel #foswiki).

Foswiki system requirements

Foswiki is capable of running on a variety of operating systems and supporting a wide range of browsers, due to its minimal client and server requirements.

Server requirements

Foswiki is written in Perl 5, which is supported on Microsoft Windows as well as Unix and Unix-like systems (including Linux and OSX), on which it uses a number of shell commands and RCS (Revision Control System), a GNU Free Software package. It should be able to run on any server platform that meets the following requirements.

Resource Required Server Environment
Perl 5.8.4 or higher is recommended. Foswiki will run in perl 5.6.1 but only with Wysiwyg editor disabled. Wysiwyg requires Unicode support which is provided by perl 5.8.1 onwards.
RCS 5.7 or higher (including GNU diff)
Optional. Foswiki includes a pure perl implementation of RCS (RcsLite) that can be used instead, at the cost of performance
GNU diff GNU diff 2.7 or higher is required when not using the all-Perl RcsLite.
Install within the PATH if not included with RCS (check version with diff -v)
Must be the version used by RCS, to avoid problems with binary attachments - RCS may have hard-coded path to diff
Other external programs fgrep, egrep
Cron/scheduler • Unix: cron
• Windows: cron equivalents
Web server Apache is well supported; for information on other servers, see Foswiki:Support.InstallingOnSpecificPlatforms.

Required CPAN modules

Most of the CPAN libraries listed below are part of a standard Perl installation. See Foswiki:Support.HowToInstallCpanModules for detailed information on how to install any CPAN libraries not present in your installation.

The following Perl CPAN modules are used by Foswiki:

Module Preferred version
Algorithm::Diff (included with Foswiki)  
CGI Versions 2.89 and 3.37 must be avoided. Most version from 3.15 and onwards should work.
CGI::Carp >=1.26
CGI::Session >=4.30 (included with Foswiki) Versions 4.20 and before have Foswikitask:Item1306
Config >=0
Cwd >=3.05
Data::Dumper >=2.121
Error (included)  
File::Copy >=2.06
File::Find >=1.05
File::Spec >=3.05
FileHandle >=2.01
IO::File >=1.10
Text::Diff (included with Foswiki)  
Time::Local >=1.11

You can check version numbers from the command line (replace "ModuleName" with the name of the module):

perl -le 'use ModuleName; print "ModuleName"->VERSION' 

Optional CPAN modules

The following Perl modules may be used by Foswiki. See Foswiki:Support.HowToInstallCpanModules for detailed information on how to install CPAN libraries.

Module Preferred version Description
Archive::Tar   May be required by the Extensions Installer in configure if command line tar or unzip is not available
CGI::Cookie >=1.24 Used for session support
Digest::base    
Digest::SHA1    
Jcode   Used for I18N support with perl 5.6
Locale::Maketext::Lexicon >=0 Used for I18N support
Net::SMTP >=2.29 Used for sending mail
Unicode::Map   Used for I18N support with perl 5.6
Unicode::Map8   Used for I18N support with perl 5.6
Unicode::MapUTF8   Used for I18N support with perl 5.6
Unicode::String   Used for I18N support with perl 5.6
URI   Used for configure

Most of these modules will probably already be present in your installation. You can check version numbers with the configure script, or if you're still trying to get to that point, check from the command line (replace "ModuleName" with the name of the module):

perl -e 'use ModuleName; print $ModuleName::VERSION."\n"' 

Client requirements

Browser clients must support the following capabilities:

  • HTML 3.2
  • Cookie support enabled, if persistent sessions are required

Most skins also require CSS and Javascript support. There is a low-fat skin (Plain) that minimises these requirements. Some skins require newer browser version. The default skin (Pattern) is tested on IE 6, Safari, and Mozilla 5.0 based browsers (such as Firefox).

You can easily select a balance of browser capability versus look and feel. Try the installed skins in the skin browser and more at Foswiki:Extensions.SkinPackage.

Uploading the Foswiki distribution to your web server host

If you cannot unpack the Foswiki distribution directly in your installation directory, you can unpack the distribution on your local computer, manually create the directory structure on your host server and upload the files as follows:

  • Using the table below, create a directory structure on your host server
  • Upload the Foswiki files by FTP (transfer as text except for the image files in pub directory.)
  • Note: Don't worry if you are not able to put the lib directory at the same level as the bin directory. You can create this directory elsewhere and configure the bin/setlib.cfg file.
    Foswiki dir: What it is: Where to copy: Example:
    foswiki start-up pages root Foswiki dir /home/smith/public_html/foswiki/
    foswiki/bin CGI bin CGI-enabled dir /home/smith/public_html/foswiki/bin
    foswiki/lib library files same level as bin /home/smith/public_html/foswiki/lib
    foswiki/locale language files dir secure from public access /home/smith/public_html/foswiki/locale
    foswiki/pub public files htdoc enabled dir /home/smith/public_html/foswiki/pub
    foswiki/data topic data dir secure from public access /home/smith/public_html/foswiki/data
    foswiki/templates web templates dir secure from public access /home/smith/public_html/foswiki/templates
    foswiki/tools Foswiki utlilities dir secure from public access /home/smith/public_html/foswiki/tools
    foswiki/working Temporary and internal files dir secure from public access /home/smith/public_html/foswiki/working

Configuring Foswiki manually (without using the configure page)

It is highly recommended that you configure Foswiki by using your browser to access the configure page. However, if you are unable to get the configure page to display (for example, if a dependency is missing), or for some reason you do not wish to use the configure page, then you can configure Foswiki manually

Perform the following steps to manually configure Foswiki:

  • Copy the file lib/Foswiki.spec to lib/LocalSite.cfg
  • Remove the # in front of the following settings, and ensure that they are set to the correct values:
       $Foswiki::cfg{DefaultUrlHost}
       $Foswiki::cfg{ScriptUrlPath}
       $Foswiki::cfg{PubUrlPath}
       $Foswiki::cfg{PubDir}
       $Foswiki::cfg{TemplateDir}
       $Foswiki::cfg{DataDir}
       $Foswiki::cfg{LocalesDir}
       $Foswiki::cfg{OS}
  • Make sure the following settings are defined:
       $Foswiki::cfg{LoginManager}
       $Foswiki::cfg{WebMasterEmail}
       $Foswiki::cfg{SMTP}{MAILHOST}
       $Foswiki::cfg{SMTP}{SENDERHOST}

Foswiki Upgrade Guide

This guide covers upgrading from a previous version of Foswiki or TWiki (such as Cairo or TWiki4.0) to Foswiki 1.0

Overview

Foswiki is a fork from TWiki 4.2.3. Upgrades from all TWiki versions and earlier Foswiki versions are supported. Foswiki is designed to be 100% compatible with the content of TWiki sites, using the same markup language and supporting the same plugin API (through the use of a TWikiCompatibilityPlugin), thereby enabling a smooth transition from TWiki to Foswiki.

Upgrade requirements

  • Please review the Foswiki:System.AdminSkillsAssumptions before you upgrade your site.
  • To upgrade from an old TWiki Release to the latest Foswiki production release, follow the instructions below.
  • Before upgrading, you may wish to make a backup of your topics.
  • Once the upgrade has been applied, an existing earlier installation will still be able to read all the topics, but should not be used to write.
  • Some TWiki plugins are not compatible with Foswiki (usually ones that use a private API or execute helper scripts); you may need to migrate to the equivalent extension in the Foswiki:Extensions repository.

Upgrading from TWiki to Foswiki

You are strongly advised to read the Foswiki:System.ReleaseNotes01x00 (also available in an HTML file in the root of your installation), which contains a list of changes from TWiki 4.2.3 to Foswiki 1.0. A number of system topics and macros (formerly known as TWiki variables) have been renamed, to better describe their purpose and, where appropriate, to rebrand to the Foswiki name.

Upgrading to a new patch release

To upgrade to a new patch release — for example, from Foswiki 1.0.0 to 1.0.3 — an upgrade package can be used that will not overwrite any of your customizations.

For patch releases you will find a brief upgrade procedure on the download page for the release. Follow this procedure to upgrade to the patch release. It may contain important steps that are unique to each patch release (for example, some configure settings may need to be changed).

Upgrade procedure: upgrading to a new major or minor version, or upgrading from TWiki

The following is a high level view of the upgrade procedure:

  1. Prepare for all upgrade steps.
  2. Install the new Foswiki version and configure it with the same settings as the old version.
  3. Install any additional extensions (Plugins) used by your old installation. Make sure to use the latest Foswiki versions.
  4. Copy all the non-default webs from the old installation to the new one.
  5. Copy the users, groups, and site customizations from the old installation to the Main web in the new installation, including all user topics.
  6. Apply preferences from the old installation.
  7. Apply your site customizations: skin, logos, menu bars, forms for personal information, and so forth.
  8. Validate your Wiki applications and other key functionality.
  9. Switch your production site from the old installation to the new installation.

More details for each step appear in the following sections. The steps may need to be modified or otherwise tailored with specifics for your installation. In particular, you must take care to preserve any special configuration or customizations you have made, especially if you have modified any of the default software files or system topics that are contained within the installation package.

For purposes of discussion, the following conventions are used:

  • <oldwiki> refers to the directory in which the old installation is located
  • <newwiki> refers to the directory in which the new installation is located; it is assumed to be immediately below the root directory of your web server
  • <old_users_web> refers to the web in which the user topics are located in the old installation. The default value is the Main web. The web is specified in the Store settings pane of the configure page, in the {UsersWebName} setting (visible when Expert mode is enabled).
  • <old_system_web> refers to the web used for documentation and default preferences in the old installation. In Foswiki, the default value is the System web; in TWiki, the default value is the TWiki web. The web is specified in the Store settings pane of the configure page, in the {SystemWebName} setting (visible when Expert mode is enabled).
After the upgrade, in the new installation, the Main web is used for user topics and site preferences, and the System web is used to hold documentation and default preferences.

The configure page mentioned in this document is accessible via your web browser at http://yourdomain/<newwiki>/bin/configure .

Prepare for all upgrade steps

Read the Foswiki:System.ReleaseNotes01x00 and learn about the differences between your old installation and the new release to which you are upgrading. Take note of any areas that affect your site and what special steps you may need to take.

Check that all the extensions (plugins, contribs, skins) used by your old installation are available with the new release. Familiarize yourself with any new behaviour that you will have to adapt to or any configuration changes you will have to perform.

If you are using authentication, prepare a test plan to verify that your authentication mechanism is working correctly. Make sure you are able to test logins by a sufficient sample of users to cover all categories of users of your site. For example, users of various groups may need to be tested. In particular, ensure you test that non-admin users cannot access topics restricted to admins.

Identify all essential Wiki topics and Wiki applications that must be fully functional upon completion of the upgrade. Prepare a test plan to verify their functionality. If you are using access controls, ensure that the test plan will adequately test all categories and groups of users of your site.

If your testing will require a test environment to be set up, ensure that it is ready, with any required support infrastructure (for example, testbed authentication servers). If you need to be able to login with different users in different categories and groups, ensure that you have the required login information ready, or you have testers from those groups available to perform the required test cases.

Download the Foswiki distribution from the following location: http://foswiki.org/Download — if you are installing your extensions manually, also download them from the repository where they are stored.

Installation

Follow the installation instructions in INSTALL.html, located in the root of the new installation. Install the new release in a new directory. Do not install on top of the old release.

  • For public or otherwise sensitive installations, ensure that your web server configuration is set to deny access to the new Foswiki installation for anyone except you.
  • Configure Foswiki using the configure page.
    • If you are upgrading from an older Foswiki release, first copy your <oldwiki>/lib/LocalSite.cfg file to <newwiki>/lib/LocalSite.cfg in order to preserve your existing configuration settings. Alternatively, you can reconfigure the new installation from scratch (you can use your old LocalSite.cfg file as a reference).
    • If you are upgrading from a TWiki site, you must reconfigure your Foswiki installation from scratch. You cannot copy over your old LocalSite.cfg file (though you can use it as a reference). Run configure and set the configuration values in the new installation to match those of the old installation.
    • Verify all of the configuration settings on the configure page, including any new settings added in the new version. Save the configuration after you have completed your changes.
    • To wipe out all your settings and start configuring from a fresh installation, just delete the <newwiki>/lib/LocalSite.cfg file and run configure.
  • Additional resources

Test your newly-installed Foswiki site and ensure that its basic functionality works: viewing and editing topics (you can try creating and editing a topic in the Sandbox web).

To make it easier to follow the subsequent steps, you can view this upgrade guide using your new Foswiki site by entering System.UpgradeGuide into the "Jump" text box on the top right of any topic. By doing this instead of using the UpgradeGuide.html file from the distribution, you will be able to use the embedded hyperlinks to jump directly to the referenced pages.

Install extensions

Install all of the extensions that were installed in your old site. In particular, start with any extensions required for the authentication and authorization methods you use (if any). You can use the Find more extensions button in the Extensions section of the configure page to install and configure extensions from the Foswiki:Extensions repository. You can also install extensions manually; see the instructions on the extension's web page from where you obtained the extension (for Foswiki extensions, on foswiki.org).

  • Note: some TWiki extensions may not work with Foswiki. By default, the TWikiCompatibilityPlugin is installed to provide backwards compatible support for TWiki plugins. However if the TWiki plugin calls private APIs or invokes helper scripts, it may still not work correctly. Check for an upgraded Foswiki version of the extension in the Foswiki:Extensions repository and install it instead.

Check the plugin topics from your old TWiki/Foswiki installation and transfer the plugin settings to the Main.SitePreferences topic in your new Foswiki site, prefixing each setting with the name of the plugin in uppercase followed by an underscore. For example, to copy over the DEFAULT_TYPE setting from the CommentPlugin topic in the old site to the new site, copy the value to a COMMENTPLUGIN_DEFAULT_TYPE setting in the Main.SitePreferences topic in the new site.

Commonly-customized plugin settings include the following:

  • CommentPlugin - DEFAULT_TYPE
  • EditTablePlugin - CHANGEROWS, QUIETSAVE, EDITBUTTON
  • InterwikiPlugin - RULESTOPIC
  • InterWikis - If you added your own rules, make sure you copy over the rules to the new installation.
  • SlideShowPlugin - If you changed the embedded 'Default Slide Template', then copy your customed template to the topic in the new installation. You should prefer creating your own slide show template in a separate topic, so you will not have to take special steps over upgrades to preserve your modifications to the default slide template.
  • SmiliesPlugin - If you added your own smileys, make sure you copy over your customizations to the topic in the new installatin.
  • TablePlugin - TABLEATTRIBUTES

Activate, and if required, configure the installed extensions in configure.

Copy content from non-default webs in old installation to the new installation

If you are upgrading from TWiki Cairo or earlier, it may be necessary to unlock the rcs files in data and pub directories from the old installation using the following shell commands:

  • find data -name '*,v' -exec rcs -u -M '{}' \;
  • find pub -name '*,v' -exec rcs -u -M '{}' \;

Copy your local webs over to the data and pub directories of the new installation. Do not copy the default webs: <old_system_web> (by default, either System or TWiki), Main, Trash, Sandbox, _default, and _empty.

  • Make sure the data and pub directories, as well as the files within them, are readable and writeable by the web server user.
  • Note: Foswiki's WebChanges topics depend on the file timestamp. If you touch the .txt files make sure to preserve the timestamp, or change them in the same chronological order as the old file timestamps.

Copy users, user topics, and site customizations to Main web

Copy all topics and attachments from <old_users_web>: copy all files from <oldwiki>/data/<old_users_web>/ to <newwiki>/data/Main/, and copy all files from <oldwiki>/pub/<old_users_web>/ to <newwiki>/pub/Main/ . Do not overwrite any topics already present in the <newwiki>/data/Main/ directory.

  • In addition to all the user topics, if you have created <old_users_web>.NewUserTemplate in the old installation, this step will copy over your template for user topics to the new installation.
  • Ensure that the topic defining the admin group in your old installation is copied over. The admin group is defined in the Security setup pane of the configure page, in the {SuperAdminGroup} setting (visible when Expert mode is enabled). You can do either of the following:
    • Set the {SuperAdminGroup} setting in your new installation to the old admin group.
    • Move the contents of the old admin group to the new admin group. To avoid having to change all references to the old admin group, you must still keep the old admin group defined: set it so its only member is the new admin group, and the new admin group is the only user who can change or rename the old admin group topic.
      • The default admin group with Foswiki is AdminGroup and the default admin group with TWiki is TWikiAdminGroup. So if you are upgrading from TWiki and are using the default admin groups, then in the new installation, you must copy all members from TWikiAdminGroup to AdminGroup, and change TWikiAdminGroup so its only member is AdminGroup and so it can only be modified or renamed by AdminGroup.
  • If your old installation did not customize {LocalSitePreferences} on the configure page, or if you did customize {LocalSitePreferences} but kept your site preferences within the <old_users_web> web, then this step will also copy over your site preferences to the new installation.

For upgrades from an older Foswiki installation:

  • Manually merge all users from the <old_users_web>.WikiUsers topic in the old installation to the Main.WikiUsers topic in the new installation. If the new installation does not yet have an initial Main.WikiUsers topic, then copy <oldwiki>/data/<old_users_web>/WikiUsers.txt to <newwiki>/data/Main/WikiUsers.txt.
  • Verify that the following default users are present in the Main.WikiUsers topic:
    • ProjectContributor - the Foswiki documentation is attributed to this user
    • RegistrationAgent - special user used during the new user registration process
    • UnknownUser - used where the author of a previously stored piece of data can't be determined
    • WikiGuest - guest user; used as a fallback if the user can't be identified
  • If any of the default users are missing, then add them in manually to Main.WikiUsers, using the corresponding entries in Foswiki:System.UsersTemplate as an example.
  • If you use data/.htpasswd for authentication, copy this file from the old installation to the new one.
  • If you have customized <old_system_web>.UserRegistration, then either copy over <oldwiki>/data/<old_system_web>/UserRegistration.txt and <oldwiki>/data/<old_system_web>/UserRegistration.txt,v to the <newwiki>/data/System/ directory, or modify System.UserRegistration in the new installation to contain your customizations.

For upgrades from a TWiki installation:

  • Manually merge all users from the <old_users_web>.TWikiUsers topic in the old installation to the Main.WikiUsers topic in the new installation. If the new installation does not yet have an initial Main.WikiUsers topic, then copy <oldwiki>/data/<old_users_web>/TWikiUsers.txt to <newwiki>/data/Main/WikiUsers.txt, and manually add the required default users (see the next steps).
  • Verify that the following default users are present in the Main.WikiUsers topic:
    • ProjectContributor - the Foswiki documentation is attributed to this user
    • RegistrationAgent - special user used during the new user registration process
    • UnknownUser - used where the author of a previously stored piece of data can't be determined
    • WikiGuest - guest user; used as a fallback if the user can't be identified
  • If any of the default users are missing, then add them in manually to Main.WikiUsers, using the corresponding entries in Foswiki:System.UsersTemplate as an example.
  • If you use data/.htpasswd for authentication, copy this file from the old installation to the new one.
  • If you are upgrading from Cairo and are using the Htpasswd login manager, run the tools/upgrade_emails.pl script to move the user emails out of the user topics and into the password file.
  • If you have customized <old_system_web>.TWikiRegistration, then modify System.UserRegistration in the new installation to contain your customizations.

Copy over any topics and attachments you want to preserve from the Sandbox web in the old installation: copy the desired files from <oldwiki>/data/Sandbox/ to <newwiki>/data/Sandbox and from <oldwiki>/pub/Sandbox/ to <newwiki>/pub/Sandbox . Some pages you may wish to preserve are the WebHome topic and the WebLeftBar topic (if you had created it in the old wiki installation). The Sandbox web often contains work-in-progress topics that users will want to keep.

Make sure the data and pub directories, as well as the files within them, are readable and writeable by the web server user.

Execute your test plans for authentication and authorization. Test that users that you have transferred from the old installation can login with any problems, and that access controls work appropriately: check that users are able to view and edit pages for which they have access, and are denied permission to view or edit pages for which they do not have access. Also check that pages restricted to the admin group are not accessible by non-admin users, and that administrators continue to have access.

Apply preferences from old installation

If you have not already set your desired site-wide preferences, as described in the section "Set Foswiki Preferences" in the System.InstallationGuide, then set your preferences. The location of your site preferences is specified in the Miscellaneous settings pane of the configure page, in the {LocalSitePreferences} setting (visible when Expert mode is enabled) — the default location is Main.SitePreferences. Copy any customized preferences from the site preferences topic in your old installation to the site preferences topic in the new installation. (Note you may have already copied over your customized preferences when you transfered the contents of the <old_users_web> web.)

If, in your old installation, you customized the default preferences in <old_system_web>.DefaultPreferences, then transfer your customizations from this topic to the site preferences topic instead (i.e. the topic specified in your {LocalSitePreferences} setting), so that your customizations will not get overwritten on the next upgrade.

If you are upgrading from TWiki, note that the default location of the default preferences in TWiki is <old_system_web>.TWikiPreferences, and the default location of the site preferences is Main.TWikiPreferences. Transfer any customized preferences from these topics to the site preferences topic in your new installation.

Apply additional site customizations

Modify skin with customizations for your site

If you did not already customize the appearance of your new installation, as described in the section "Customize the appearance of your Foswiki site" in the System.InstallationGuide, then reapply the customizations from your old installation to the new one. Ensure you transfer over any skin templates — .tmpl files, or topics referred to using VIEW_TEMPLATE or EDIT_TEMPLATE preferences — you need. Also ensure you transfer any style sheets or Javascript files required.

If you are upgrading from the Cairo version of TWiki: note that the skins from this release do not work well with Foswiki. Starting from TWiki 4.0.2, the default PatternSkin has been fairly stable and so your customizations should continue to work.

Customize pages for managing personal information

In your new installation, default copies of the following topics were installed:

If you customized these topics in your old installation, transfer the changes to these topics in the new installation. Use the corresponding files in the <oldwiki>/<old_system_web>/ directory as a reference.

Validate your Wiki applications and other key functionality

Execute your test plan to validate the Wiki applications and other key functionality that need to be up and running after the upgrade.

Switch your production site from the old installation to the new installation

If you had been running your old installation in parallel with the new one during a test phase, then disable your old installation, and repeat the step "Copy content from non-default webs in old installation to the new installation".

Change your web server configuration so that the new installation is accessible to all of your users, and so the old installation is no longer accessible.

Change your web server configuration so that the new installation is accessible using the same URL prefix as your old installation. For purposes of discussion, assume that your old installation is accessible from http://yourdomain/wiki/. You can use one of the following approaches to make the new installation accessible using the same URL prefix:

  • You can rename your <newwiki>/ directory to wiki/ (renaming the directory of your old installation if necessary).
  • If your operating system supports links to other directories and your web server is configured to follow links, then you can create a link called wiki/ that points to <newwiki>/ (renaming the directory of your old installation if necessary).
  • You can configure your web server so that requests to /wiki/ are served from your <newwiki>/ directory.

Re-execute your test plan to verify that your newly-upgraded site is accessible to your users, and that all authentication and authorization mechanisms work as expected (including denying access to those who are not authorized).

Re-execute your test plan to verify that your Wiki applications and other key functionality work as intended.

Additional steps when upgrading from TWiki Cairo

Favicon

The favicon is now configurable as a site preference or per-web preference. See System.DefaultPreferences for a description of the FAVICON preference. To set it for your site, add the FAVICON preference to your site preferences topic, Main.SitePreferences (or the topic you configured in your {LocalSitePreferences} setting in the Miscellaneous settings pane on the configure page). To set it for a web, add the FAVICON preference to the WebPreferences topic for that web.

Important changes since TWiki 4.0.5

Supported Perl version

To use Foswiki, you must use Perl 5.8 or higher. Foswiki no longer supports Perl version 5.6.x (the minimum version required for TWiki 4.0.5).

Template spec changed

Until TWiki 4.0.5, any text inside template definition blocks for SkinTemplates (formerly called TWikiTemplates) — that is, between %TMPL:DEF{"block"}% and %TMPL:END% — was stripped of leading and trailing white space, including newlines. This made it difficult for skin developers to include a newline before or after a block of text.

From TWiki 4.1.0 onwards, and in Foswiki 1.0, this has changed so that white space is no longer stripped. Skins like PatternSkin and NatSkin have been updated so that they work with the new behavior. If you use an older skin or have written your own you will most likely need to make some adjustments.

In general, if you get mysterious blank lines in your skin, the newline after the %TMPL:DEF{"block"}% needs to be removed: the content of the block must follow on the same line as the TMPL:DEF.

CommentPlugin templates also must be modified to remove extraneous newlines — in particular, any newline immediately after the TMPL:DEF. See the System.CommentPluginTemplate for examples of how comment template definitions should look like in TWiki 4.1.x.

Example: a CommentPlugin template that adds a row to a table. With versions of TWiki prior to 4.1, the following syntax can be used:

%TMPL:DEF{OUTPUT:tabletest}%%POS:BEFORE%
|%URLPARAM{"comment"}%| -- %WIKIUSERNAME% - %DATE% |
%TMPL:END%

Starting in TWiki 4.1 and continuing with Foswiki 1.0, the newline before the start of the table row must be removed:

%TMPL:DEF{OUTPUT:tabletest}%%POS:BEFORE%|%URLPARAM{"comment"}%| -- %WIKIUSERNAME% - %DATE% |
%TMPL:END%

Important changes for the upgrader - since TWiki 4.1.0

New location for session and other temporary files

The directory for passthrough and session files have been replaced by a common directory for temporary files used by Foswiki. Previously the two configure settings {PassthroughDir} and {Sessions}{Dir} were set by default to /tmp. These config settings have been eliminated: Foswiki creates a tmp directory and other temporary directories under the directory defined by the configure setting {WorkingDir}.

Important changes for the upgrader - since TWiki 4.1.2

New WYSIWYG editor

Foswiki now ships with a new WYSIWYG editor based on TinyMCE that replaces the Kupu-based editor. When TinyMCEPlugin is enabled, the Edit button will initiate WYSIWYG editing mode. A Raw Edit link has been added for users to edit the topic markup directly.

The WYSIWYG button has been removed.

NEWTOPICLINKSYMBOL removed

The NEWTOPICLINKSYMBOL preference that was deprecated in TWiki 4.1 is no longer supported. To control the appearance of new links, set the NEWLINKFORMAT preference in Main.SitePreferences (see System.DefaultPreferences for more information on NEWLINKFORMAT).

UserForm and NewUserTemplate customization

When a new user registers on Foswiki his user topic is created based on the NewUserTemplate and UserForm in the Main web, if they exist. If the topic does not exist in the Main web, then the default version from System is used. Thus on upgrades, any customizations you made to NewUserTemplate or UserForm in the Main web will be preserved.

In previous TWiki versions, only System.NewUserTemplate and System.UserForm are used; you cannot override them by creating your own version in the Main web.

WikiUsers no longer distributed

The Main.WikiUsers topic contains all the registered users. It is not included in the Foswiki distribution, so that your list of users will not be overwritten on upgrades. When the first user is registered in Foswiki, the Main.WikiUsers topic is created on demand.

New working directory

The configuration setting {WorkingDir} in the General path settings pane on the configure page defines the location of a working directory for various subdirectories for use by Foswiki. The default value for this setting is the working subdirectory within the installation root directory for the Foswiki installation.

The subdirectories within the working directory include the following:

  • registration_approvals — previously located in the data/ directory
  • tmp — avoids security issues with using the /tmp directory
  • work_areas — previously located in the pub/ directory.

Note: Remember to restrict access to this new directory when you upgrade.

If you have your own scheduled task to delete obsolete session files, note they are now located in the working/tmp/ subdirectory.

New internal admin login

Foswiki has a new internal admin login feature that lets you login as a temporary administrator, using "admin" as your user name and the password for the configure page. The internal admin username can be configured in the {AdminUserLogin} setting in the Security setup pane on the configure page.

In order to add an initial user to the default {SuperAdminGroup}, Main.AdminGroup, you must login as the internal admin user using the link on the Main.AdminGroup page.

Important changes for the upgrader - since Foswiki 1.0.4

An additional security feature has been added to Foswiki 1.0.5 so that saving data now requires the http method POST. This means that it is no longer possible to store data via an "<a href=..." link or img tag. It also means that if you have an application with an HTML form that creates new topics you must specify in the form tag method="post". This change is done to further tighten the security of Foswiki.

<form name="new" action="%SCRIPTURLPATH{save}%/Sandbox/" method="post">
    ...
</form>

The template webs _default and _empty are frequent targets for spammers because these webs are normally not monitored very carefully by the community around a Foswiki installation. These webs are now write protected so on an administrator can edit topics in these webs. When an administrator creates a new web it is important to remember to remove the access restriction from the WebPreferences in the new web.

Important changes for the upgrader - since Foswiki 1.0.5

Foswiki 1.0.6 introduces a major security enhancement, protecting against Cross-Site Request Forgery. The extra safe "double submit" algorithm, as recommended by the Open Web Application Security Project (OWASP) project has been used. This is the same algorithm used by several major banks and other security-conscious institutions, and requires that users have Javascript enabled.

See Foswiki:Support.SecurityFeatures for more information on these, and other, Foswiki security features. This is recommended reading for all Foswiki administrators.

If these new countermeasures against CSRF creates problems for your users and your applications, you can alter the way the protection works or disable it. These are the configure parameters you need to visit (note that some are expert settings).

  • {Validation}{Method} is by default "strikeone" which is the highest level of security and requires that users have Javascript enabled. You can lower this setting to "embedded" which uses a less safe validation method but does not require javascript. If you want to disable CSRF protection set it to "none". It is highly recommended to keep it at "strikeone".
  • {Validation}{ValidForTime} is the time the validation key is valid. It is by default 1 hour. If your users often edit pages longer you can increase this time. Your users can still save pages with an expired validation key but they will be asked to confirm the saving.
  • {Validation}{MaxKeysPerSession} is the maximum number of validation keys to store in a session. There is one key stored for each page rendered. If the number of keys exceeds this number, the oldest keys will be force-expired to bring the number down. If you have users that are very fast at editing pages and experience expired keys, you can increase this number. The default is 1000 and should be much higher than any normal person will experience.
  • {Validation}{ExpireKeyOnUse} defines if validation keys expire when they are used for storing data. This prevents an attacker from evesdropping communication between server and browser and reuse keys. Unfortunately it also means that if a user edits a page, saves it, uses the back button of the browser, corrects his previous editing, and then saves again, he is asked to confirm that he intended to save the topic. Another use case is if you create an application with multiple forms and multiple submit buttons on a topic and you submit multiple times from this topic without navigating away from it, you will be asked to confirm the submission each time. If this is not acceptable to your use of Foswiki, you can turn off {Validation}{ExpireKeyOnUse}.

User Authentication

Controlling who can access your site

Overview

Authentication, or "login", is the process by which a user lets STALklubben know who they are.

Authentication isn't just to do with access control. STALklubben uses authentication to keep track of who made changes, and manage a wide range of personal settings. With authentication enabled, users can personalise STALklubben and contribute as recognised individuals, instead of shadows.

STALklubben authentication is very flexible, and can either stand alone or integrate with existing authentication schemes. You can set up STALklubben to require authentication for every access, or only for changes. Authentication is also essential for access control.

Quick Authentication Test - Use the %USERINFO% macro to return your current identity:

  • You are guest, Main.WikiGuest,

STALklubben user authentication is split into four sections; password management, user mapping, user registration, and login management. Password management deals with how users personal data is stored. Registration deals with how new users are added to the wiki. Login management deals with how users log in.

Once a user is logged on, they can be remembered using a Client Session stored in a cookie in the browser (or by other less elegant means if the user has disabled cookies). This avoids them having to log on again and again.

STALklubben user authentication is configured through the Security Settings pane in the configure interface.

Please note FileAttachments are not protected by STALklubben User Authentication.

Password Management

As shipped, STALklubben supports the Apache 'htpasswd' password manager. This manager supports the use of .htpasswd files on the server. These files can be unique to STALklubben, or can be shared with other applications (such as an Apache webserver). A variety of password encodings are supported for flexibility when re-using existing files. See the descriptive comments in the Security Settings section of the configure interface for more details.

You can easily plug in alternate password management modules to support interfaces to other third-party authentication databases.

The password manager is selected using the {PasswordManager} setting in configure.

User Mapping

Usually when you are using an external authentication method, you want to map from an unfriendly "login name" to a more friendly WikiName. Also, an external authentication database may well have user information you want to import to STALklubben, such as user groups.

By default, STALklubben supports mapping of usernames to wikinames, and supports STALklubben groups internal to STALklubben. If you want, you can plug in an alternate user mapping module to support import of groups etc.

The user mapping manager is selected using the {UserMappingManager} setting in configure.

User Registration

New user registration uses the password manager to set and change passwords and store email addresses. It is also responsible for the new user verification process. the registration process supports single user registration via the UserRegistration page, and bulk user registration via the BulkRegistration page (for admins only).

The registration process is also responsible for creating user topics, and setting up the mapping information used by the User Mapping support.

Login Management

Login management controls the way users have to log in. There are three basic options; no login, login via a STALklubben login page, and login using the webserver authentication support. the login manager is selected using the {LoginManager} setting in configure.

No Login (select none)

Does exactly what it says on the tin. Forget about authentication to make your site completely public - anyone can browse and edit freely, in classic Wiki style. All visitors are given the Main.WikiGuest default identity, so you can't track individual user activity.

ALERT! Note: This setup is not recommended on public websites for security reasons; anyone would be able to change system settings and perform tasks usually restricted to administrators.

Template Login (select Foswiki::LoginManager::TemplateLogin)

Template Login asks for a username and password in a web page, and processes them using whatever Password Manager you choose. Users can log in and log out. Client Sessions are used to remember users. Users can choose to have their session remembered so they will automatically be logged in the next time they start their browser.

Enabling Template Login

  1. Use the configure interface to
    1. select the Foswiki::LoginManager::TemplateLogin login manager (on the Security Settings pane).
    2. select the appropriate password manager for your system, or provide your own.
    3. HELP there is also an EXPERT configure setting {TemplateLogin}{PreventBrowserRememberingPassword} that you can set to prevent Browsers from remembering username and passwords if you are concerned about public terminal usage.
  2. Register yourself in the UserRegistration topic.
    HELP Check that the password manager recognises the new user. If you are using .htpasswd files, check that a new line with the username and encrypted password is added to the .htpasswd file. If not, you probably got a path wrong, or the permissions may not allow the webserver user to write to that file.
  3. Create a new topic to check if authentication works.
  4. Edit the Main.AdminGroup topic in the Main web to include users with system administrator status.
    ALERT! This is a very important step, as users in this group can access all topics, independent of STALklubben access controls.

AccessControl has more information on setting up access controls.

ALERT! At this time AccessControls cannot control access to files in the pub area, unless they are only accessed through the viewfile script. If your pub directory is set up in the webserver to allow open access you may want to add .htaccess files in there to restrict access.

TIP You can create a custom version of the UserRegistration form by copying the topic, and then deleting or adding input tags in your copy. The name="" parameter of the input tags must start with: "Twk0..." (if this is an optional entry), or "Twk1..." (if this is a required entry). This ensures that the fields are carried over into the user home page correctly. Do not modify the version of UserRegistration shipped with STALklubben, as your changes will be overwritten next time you upgrade.

TIP The default new user template page is in System.NewUserTemplate. The same macros get expanded as in the template topics. You can create a custom new user home page by creating the Main.NewUserTemplate? topic, which will then override the default.

Apache Login (select Foswiki::LoginManager::ApacheLogin)

Using this method STALklubben does not authenticate users internally. Instead it depends on the REMOTE_USER environment variable, which is set when you enable authentication in the webserver.

The advantage of this scheme is that if you have an existing website authentication scheme using Apache modules such as mod_auth_ldap or mod_auth_mysql you can just plug in directly to them.

The disadvantage is that because the user identity is cached in the browser, you can log in, but you can't log out again unless you restart the browser.

STALklubben maps the REMOTE_USER that was used to log in to the webserver to a WikiName using the table in Main.WikiUsers. This table is updated whenever a user registers, so users can choose not to register (in which case their webserver login name is used for their signature) or register (in which case that login name is mapped to their WikiName).

The same private .htpasswd file used in STALklubben Template Login can be used to authenticate Apache users, using the Apache Basic Authentication support.

Warning: Do not use the Apache htpasswd program with .htpasswd files generated by STALklubben! htpasswd wipes out email addresses that STALklubben plants in the info fields of this file.

Enabling Apache Login using mod_auth

You can use any other Apache authentication module that sets REMOTE_USER.
  1. Use configure to select the Foswiki::LoginManager::ApacheLogin login manager.
  2. Use configure to set up STALklubben to create the right kind of .htpasswd entries.
  3. Create a .htaccess file in the bin directory.
    HELP There is an template for this file in bin/.htaccess.txt that you can copy and change. The comments in the file explain what need to be done.
    HELP If you got it right, the browser should now ask for login name and password when you click on the Edit. If .htaccess does not have the desired effect, you may need to "AllowOverride All" for the directory in httpd.conf (if you have root access; otherwise, e-mail web server support)
    ALERT! At this time AccessControls do not control access to files in the pub area, unless they are only accessed through the viewfile script. If your pub directory is set up to allow open access you may want to add .htaccess files in there as well to restrict access
  4. You can create a custom version of the UserRegistration form by copying the default topic, and then deleting or adding input tags in your copy. The name="" parameter of the input tags must start with: "Twk0..." (if this is an optional entry), or "Twk1..." (if this is a required entry). This ensures that the fields are carried over into the user home page correctly. Do not modify the version of UserRegistration shipped with STALklubben, as your changes will be overwritten next time you upgrade.
    The default new user template page is in System.NewUserTemplate. The same macros get expanded as in the template topics. You can create a custom new user home page by creating the Main.NewUserTemplate? topic, which will then override the default.
  5. Register yourself in the UserRegistration topic.
    HELP Check that a new line with the username and encrypted password is added to the .htpasswd file. If not, you may have got a path wrong, or the permissions may not allow the webserver user to write to that file.
  6. Create a new topic to check if authentication works.
  7. Edit the Main.AdminGroup topic in the Main web to include users with system administrator status.
    ALERT! This is a very important step, as users in this group can access all topics, independent of STALklubben access controls.
AccessControl has more information on setting up access controls.

Logons via bin/logon

Any time a user requests a page that needs authentication, they will be forced to log on. It may be convenient to have a "logon" link as well, to give the system a chance to identify the user and retrieve their personal settings. It may be convenient to force them to log on.

The bin/logon script enables this. If you are using Apache Login, the bin/logon script must be setup in the bin/.htaccess file to be a script which requires a valid user. Once authenticated, it will redirect the user to the view URL for the page from which the logon script was linked.

Sessions

STALklubben uses the CPAN:CGI::Session and CPAN:CGI::Cookie modules to track sessions. These modules are de facto standards for session management among Perl programmers. If you can't use Cookies for any reason, CPAN:CGI::Session also supports session tracking using the client IP address.

You don't have to enable sessions to support logins in STALklubben. However it is strongly recommended. STALklubben needs some way to remember the fact that you logged in from a particular browser, and it uses sessions to do this. If you don;t enable sessions, STALklubben will try hard to remember you, but due to limitations in the browsers it may also forget you (and then suddenly remember you again later!). So for the best user experience, you should enable sessions.

There are a number of macros available that you can use to interrogate your current session. You can even add your own session variables to the STALklubben cookie. Session variables are referred to as "sticky" variables.

Getting, Setting, and Clearing Session Variables

You can get, set, and clear session variables from within STALklubben web pages or by using script parameters. This allows you to use the session as a personal "persistent memory space" that is not lost until the web browser is closed. Also note that if a session variable has the same name as a STALklubben preference, the session variables value takes precedence over the STALklubben preference. This allows for per-session preferences.

To make use of these features, use the tags:

%SESSION_VARIABLE{ "varName" }%
%SESSION_VARIABLE{ "varName" set="varValue" }%
%SESSION_VARIABLE{ "varName" clear="" }%

Note that you cannot override access controls preferences this way.

Cookies and Transparent Session IDs

STALklubben normally uses cookies to store session information on a client computer. Cookies are a common way to pass session information from client to server. STALklubben cookies simply hold a unique session identifier that is used to look up a database of session information on the STALklubben server.

For a number of reasons, it may not be possible to use cookies. In this case, STALklubben has a fallback mechanism; it will automatically rewrite every internal URL it sees on pages being generated to one that also passes session information.

Username vs. Login Username

This section applies only if you are using authentication with existing login names (i.e. mapping from login names to WikiNames).

STALklubben internally manages two usernames: Login Username and Foswiki Username.

  • Login Username: When you login to the intranet, you use your existing login username. This name is normally passed to Foswiki by the REMOTE_USER environment variable, and used internally. Login Usernames are maintained by your system administrator.

  • Foswiki Username: Your name in WikiNotation, ex: JohnSmith, is recorded when you register using UserRegistration; doing so also generates a personal home page in the Main web.

Foswiki can automatically map an Intranet (Login) Username to a Foswiki Username if the {AllowLoginName} is enabled in configure. The default is to use your WikiName as a login name.

NOTE: To correctly enter a WikiName - your own or someone else's - be sure to include the Main web name in front of the Wiki username, followed by a period, and no spaces, for example Main.WikiUsername or %USERSWEB%.WikiUsername. This points WikiUsername to the Main web, where user home pages are located, no matter which web it's entered in. Without the web prefix, the name appears as a NewTopic everywhere but in the Main web.

Changing Passwords

If your {PasswordManager} supports password changing, you can change and reset passwords using forms on regular pages.

  • The ChangePassword form ( Foswiki/ChangePassword )
  • The ResetPassword form ( Foswiki/ResetPassword )

Changing E-mail Addresses

If the active {PasswordManager} supports storage and retrieval of user e-mail addresses, you can change your e-mail using a regular page. As shipped, this is true only for the Apache 'htpasswd' password manager.

  • The ChangeEmailAddress form ( Foswiki/ChangeEmailAddress )

Controlling access to individual scripts

You may want to add or remove scripts from the list of scripts that require authentication. The method for doing this is different for each of Template Login and Apache Login.
  • For Template Login, update the {AuthScripts} list using configure
  • For Apache Login, add/remove the script from .htaccess

How to choose an authentication method

One of the key features of Foswiki is that it is possible to add HTML to topics. No authentication method is 100% secure on a website where end users can add HTML, as there is always a risk that a malicious user can add code to a topic that gathers user information, such as session IDs. The Foswiki developers have been forced to make certain tradeoffs, in the pursuit of efficiency, that may be exploited by a hacker.

This section discusses some of the known risks. You can be sure that any potential hackers have read this section as well!

At one extreme, the most secure method is to use Foswiki via SSL (Secure Sockets Layer), with a login manager installed and Client Sessions turned off.

Using Foswiki with sessions turned off is a pain, though, as with all the login managers there are occasions where Foswiki will forget who you are. The best user experience is achieved with sessions turned on.

As soon as you allow the server to maintain information about a logged-in user, you open a door to potential attacks. There are a variety of ways a malicious user can pervert Foswiki to obtain another users session ID, the most common of which is known as a cross-site scripting attack. Once a hacker has an SID they can pretend to be that user.

To help prevent these sorts of attacks, Foswiki supports IP matching, which ensures that the IP address of the user requesting a specific session is the same as the IP address of the user who created the session. This works well as long as IP addresses are unique to each client, and as long as the IP address of the client can't be faked.

Session IDs are usually stored by Foswiki in cookies, which are stored in the client browser. Cookies work well, but not all environments or users permit cookies to be stored in browsers. So Foswiki also supports two other methods of determining the session ID. The first method uses the client IP address to determine the session ID. The second uses a rewriting method that rewrites local URLs in Foswiki pages to include the session ID in the URL.

The first method works well as long as IP addresses are unique to each individual client, and client IP addresses can't be faked by a hacker. If IP addresses are unique and can't be faked, it is almost as secure as cookies + IP matching, so it ranks as the fourth most secure method.

If you have to turn IP matching off, and cookies can't be relied on, then you may have to rely on the second method, URL rewriting. This method exposes the session IDs very publicly, so should be regarded as "rather dodgy".

Most Foswiki sites don't use SSL, so, as is the case with most sites that don't use SSL, there is always a possibility that a password could be picked out of the aether. Browsers do not encrypt passwords sent over non-SSL links, so using Apache Login is no more secure than Template Login.

Of the two shipped login managers, Apache Login is probably the most useful. It lets you do this sort of thing: wget --http-user=RogerRabbit --http-password=i'mnottelling http://www.example.com/bin/save/Sandbox/StuffAUTOINC0?text=hohoho,%20this%20is%20interesting i.e. pass in a user and password to a request from the command-line. However it doesn't let you log out.

Template Login degrades to url re-writing when you use a client like dillo that does not support cookies. However, you can log out and back in as a different user.

Finally, it would be really neat if someone was to work out how to use certificates to identify users.....

See Foswiki:Support.SupplementalDocuments for more information.

Access Control

Restricting read and write access to topics and webs, by users and groups

Access Control allows you restrict access to single topics and entire webs, by individual user and by user Groups. Access control, combined with UserAuthentication, lets you easily create and manage an extremely flexible, fine-grained privilege system.

An important control consideration

Open, freeform editing is the essence of WikiCulture - what makes Foswiki different and often more effective than other collaboration tools. For that reason, it is strongly recommended that decisions to restrict read or write access to a web or a topic are made with great care - the more restrictions, the less Wiki in the mix. Experience shows that unrestricted write access works very well because:

  • Peer influence is enough to ensure that only relevant content is posted.
  • Peer editing - the ability for anyone to rearrange all content on a page - keeps topics focused.
  • In Foswiki, content is transparently preserved under revision control:
    • Edits can be undone by the administrator (per default a member of Main.AdminGroup; see #ManagingGroups).
    • Users are encouraged to edit and refactor (condense a long topic), since there's a safety net.
As a collaboration guideline:
  • Create broad-based Groups (for more and varied input), and...
  • Avoid creating view-only Users (if you can read it, you should be able to contribute to it).

  • Main.WikiGuest is the guest account - used by unauthenticated users.
  • The web must not deny view to Main.WikiGuest; otherwise, people will not be able to register.

HELP Above table comes from SitePermissions

Authentication vs. Access Control

Authentication: Identifies who a user is based on a login procedure. See UserAuthentication.

Access control: Restrict access to content based on users and groups once a user is identified.

Users and groups

Access control is based on the familiar concept of users and groups. Users are defined by their WikiNames. They can then be organized in unlimited combinations by inclusion in one or more user Groups. For convenience, Groups can also be included in other Groups.

Managing Users

A user can create an account in UserRegistration. The following actions are performed:

  • WikiName and encrypted password are recorded using the password manager if authentication is enabled.
  • A confirmation e-mail is sent to the user.
  • A user home page with the WikiName of the user is created in the Main web.
  • The user is added to the Main.WikiUsers topic.

The default visitor name is Main.WikiGuest. This is the non-authenticated user.

Managing Groups

The following describes the standard Foswiki support for groups. Your local Foswiki may have an alternate group mapping manager installed. Check with your Wiki administrator if you are in doubt.

Groups are defined by group topics located in the Main web. To create a new group, visit Main.WikiGroups and enter the name of the new group ending in Group into the "new group" form field. This will create a new group topic with two important settings:

  • Set GROUP = < list of users and/or groups >
  • Set ALLOWTOPICCHANGE = < list of users and/or groups >

The GROUP setting is a comma-separated list of users and/or other groups. Example:

  • Set GROUP = Main.SomeUser, Main.OtherUser, Main.SomeGroup

The ALLOWTOPICCHANGE setting defines who is allowed to change the group topic; it is a comma delimited list of users and groups. You typically want to restrict that to the members of the group itself, so it should contain the name of the topic. This prevents users not in the group from editing the topic to give themselves or others access. For example, for the KasabianGroup topic write:

  • Set ALLOWTOPICCHANGE = Main.KasabianGroup

ALERT! Foswiki has strict formatting rules. Make sure you have three spaces, an asterisk, and an extra space in front of any access control rule.

The Super Admin Group

A number of Foswiki functions (for example, renaming webs) are only available to administrators. Administrators are simply users who belong to the SuperAdminGroup. This is a standard user group, the name of which is defined by {SuperAdminGroup} setting in configure. The default name of this group is the AdminGroup. The system administrator may have chosen a different name for this group if your local Foswiki uses an alternate group mapping manager but for simplicity we will use the default name AdminGroup in the rest of this topic.

You can create new administrators simply by adding them to the Main.AdminGroup topic. For example,

  • Set GROUP = Main.ElizabethWindsor, Main.TonyBlair
A member of the Super Admin Group has unrestricted access throughout the Foswiki, so only trusted staff should be added to this group.

Restricting Access

You can define who is allowed to read or write to a web or a topic. Note that some plugins may not respect access permissions.

  • Restricting VIEW blocks viewing and searching of content. When you restric VIEW to a topic or web, this also restricts INCLUDE and Formatted SEARCH from showing the content of the topics.
  • Restricting CHANGE blocks creating new topics, changing topics or attaching files.
  • Restricting RENAME prevents renaming of topics within a web.

ALERT! There is an important distinction between CHANGE access and RENAME access. A user can CHANGE a topic, but thanks to version control their changes cannot be lost (the history of the topic before the change is recorded). However if a topic or web is renamed, that history may be lost. Typically a site will only give RENAME access to administrators and content owners.

Controlling access to a Web

You can define restrictions on who is allowed to view a STALklubben web. You can restrict access to certain webs to selected users and groups, by:

  • authenticating all webs and restricting selected webs: Topic access in all webs is authenticated, and selected webs have restricted access.
  • authenticating and restricting selected webs only: Provide unrestricted viewing access to open webs, with authentication and restriction only on selected webs.

  • You can define these settings in the WebPreferences topic, preferable towards the end of the topic:
    • Set DENYWEBVIEW = < comma-delimited list of users and groups >
    • Set ALLOWWEBVIEW = < comma-delimited list of users and groups >
    • Set DENYWEBCHANGE = < comma-delimited list of users and groups >
    • Set ALLOWWEBCHANGE = < comma-delimited list of users and groups >
    • Set DENYWEBRENAME = < comma-delimited list of users and groups >
    • Set ALLOWWEBRENAME = < comma-delimited list of users and groups >

If your site allows hierarchical webs, then access to sub-webs is determined from the access controls of the parent web, plus the access controls in the sub-web. So, if the parent web has ALLOWWEBVIEW set, this will also apply to the subweb. Also note that you will need to ensure that the parent web's FINALPREFERENCES does not include the access control settings listed above. Otherwise you will not be able override the parent web's access control settings in sub-webs.

Creation and renaming of sub-webs is controlled by the WEBCHANGE setting on the parent web (or ROOTCHANGE for root webs). Renaming is additionally restricted by the setting of WEBRENAME in the web itself.

Controlling access to a topic

  • You can define these settings in any topic, preferable towards the end of the topic:
    • Set DENYTOPICVIEW = < comma-delimited list of users and groups >
    • Set ALLOWTOPICVIEW = < comma-delimited list of users and groups >
    • Set DENYTOPICCHANGE = < comma-delimited list of users and groups >
    • Set ALLOWTOPICCHANGE = < comma-delimited list of users and groups >
    • Set DENYTOPICRENAME = < comma-delimited list of users and groups >
    • Set ALLOWTOPICRENAME = < comma-delimited list of users and groups >

Remember when opening up access to specific topics within a restricted web that other topics in the web - for example, the WebLeftBar - may also be accessed when viewing the topics. The message you get when you are denied access should tell you what topic you were not permitted to access.

Be careful with empty values for any of these.

  • Set ALLOWTOPICVIEW =
    This means the same as not setting it at all. (This was documented wrong in versions 4.0.X, 4.1.0 and 4.1.1)

  • Set DENYTOPICVIEW =
    This means do not deny anyone the right to view this topic. If DENYTOPICVIEW is set to an empty value anyone has access even if ALLOWTOPICVIEW or ALLOWWEBVIEW is defined. This allows you to have very restrictive default access rights to an entire web and still allow individual topics to have more open access.

The same rules apply to ALLOWTOPICCHANGE/DENYTOPICCHANGE and APPLYTOPICRENAME/DENYTOPICRENAME. Setting ALLOWTOPICCHANGE or ALLOWTOPICRENAME to en empty value means the same as not defining it. Setting DENYTOPICCHANGE or DENYTOPICRENAME to an empty value means that anyone can edit or rename the topic.

ALERT! If the same setting is defined multiple times the last one overrides the previous. They are not OR'ed together.

ALERT! The setting to an empty has caused confusion and great debate and it has been decided that the empty setting syntax will be replaced by something which is easier to understand in a later version of Foswiki. A method to upgrade will be provided. Please read the release notes carefully when you upgrade.

See "How Foswiki evaluates ALLOW/DENY settings" below for more on how ALLOW and DENY interacts.

Controlling access to attachments

Attachments are referred to directly, and are not normally indirected via Foswiki scripts. This means that the above instructions for access control will not apply to attachments. It is possible that someone may inadvertently publicise a URL that they expected to be access-controlled.

The easiest way to apply the same access control rules for attachments as apply to topics is to use the Apache mod_rewrite module, and configure your webserver to redirect accesses to attachments to the Foswiki viewfile script. For example,

    ScriptAlias /foswiki/bin/ /filesystem/path/to/bin/
    Alias /foswiki/pub/       /filesystem/path/to/pub/

    RewriteEngine on
    RewriteCond %{REQUEST_URI} !^/+foswiki/+pub/+System/+.+
    RewriteRule ^/+foswiki/+pub/+([^/]+)((/+([^/]+))+)/+(.+) /foswiki/bin/viewfile/$1/$2?filename=$5 [L,PT]

That way all the controls that apply to the topic also apply to attachments to the topic. Other types of webserver have similar support.

HELP Images embedded in topics will load much slower since each image will be delivered by the viewfile script.

Controlling who can manage top-level webs

Top level webs are a special case, because they don't have a parent web with a WebPreferences. So there has to be a special control just for the root level.

  • You can define these settings in the Main.DefaultPreferences topic, preferable towards the end of the topic:
    • Set DENYROOTCHANGE = < comma-delimited list of users and groups >
    • Set ALLOWROOTCHANGE = < comma-delimited list of users and groups >
Note that you do not require ROOTCHANGE access to rename an existing top-level web. You just need WEBCHANGE in the web itself.

How Foswiki evaluates ALLOW/DENY settings

When deciding whether to grant access, Foswiki evaluates the following rules in order (read from the top of the list; if the logic arrives at PERMITTED or DENIED that applies immediately and no more rules are applied). You need to read the rules bearing in mind that VIEW, CHANGE and RENAME access may be granted/denied separately.

  1. If the user is an administrator
    • access is PERMITTED.
  2. If DENYTOPIC is set to a list of wikinames
    • people in the list will be DENIED.
  3. If DENYTOPIC is set to empty ( i.e. Set DENYTOPIC = )
    • access is PERMITTED i.e no-one is denied access to this topic.
      ALERT! Attention: Use this with caution. This is deprecated and will likely change in the next release.
  4. If ALLOWTOPIC is set
    1. people in the list are PERMITTED
    2. everyone else is DENIED
  5. If DENYWEB is set to a list of wikinames
    • people in the list are DENIED access
  6. If ALLOWWEB is set to a list of wikinames
    • people in the list will be PERMITTED
    • everyone else will be DENIED
  7. If you got this far, access is PERMITTED

Access control and INCLUDE

ALLOWTOPICVIEW and ALLOWTOPICCHANGE only applies to the topic in which the settings are defined. If a topic A includes another topic B, topic A does not inherit the access rights of the included topic B.

Examples: Topic A includes topic B

  • If the included topic B has ALLOWTOPICCHANGE set to block editing for a user, it does not prevent editing the including topic A.
  • If the included topic B has ALLOWTOPICVIEW set to block view for a user, the user can still view topic A but he cannot see the included topic B. He will see a message No permission to view B

Access control quick recipes

Obfuscating webs

Another way of hiding webs is to keep them hidden by not publishing the URL and by preventing the all webs search option from accessing obfuscated webs. Do so by enabling the NOSEARCHALL setting in WebPreferences:

  • Set NOSEARCHALL = on

This setup can be useful to hide a new web until content its ready for deployment, or to hide view access restricted webs.

ALERT! Obfuscating a web without view access control is very insecure, as anyone who knows the URL can access the web.

Restrict Access to a whole Foswiki site

For a firewalled Foswiki, e.g. an intranet wiki or extranet wiki, you want to allow only invited people to access your Foswiki. In this case, enable user authentication with ApacheLogin and lock down access to the whole bin and pub directories to all but valid users. In the Apache .htaccess file or the appropriate .conf file, replace the <FilesMatch "(attach|edit|... section with this:

<FilesMatch ".*">
       require valid-user
</FilesMatch>

If needed, you can further restrict access to selected webs with ALLOWWEBVIEW and other access control settings.

HELP With this configuration, someone with access to the site needs to register new users.

Authenticate all webs and restrict selected webs

Use the following setup to authenticate users for topic viewing in all webs and to restrict access to selected webs. Requires UserAuthentication to be enabled.

  1. The simple way is to add this to WebPreferences in all webs.
    • Set DENYWEBVIEW = WikiGuest
  2. Restrict view access to selected users and groups. Set one or both of these settings in its WebPreferences topic:
    • Set ALLOWWEBVIEW = < list of users and groups >
    • Note: DENYWEBVIEW is evaluated before ALLOWWEBVIEW. Access is denied if the authenticated person is in the DENYWEBVIEW list, or not in the ALLOWWEBVIEW list. Access is granted if DENYWEBVIEW and ALLOWWEBVIEW are not defined.

In rare cases it may be required to authenticate the view script. This can in some cases have a dramatic performance hit because the webserver must re-authenticate for every page view.

  1. Set require valid-user on your view script in .htaccess or the appropriate Apache .conf file. This looks like: FilesMatch "(attach|edit|manage|rename|save|view|upload|mail|logon|.*auth).*" (normally view is not in that list).

Authenticate and restrict selected webs only

Use the following setup to provide unrestricted viewing access to open webs, with authentication only on selected webs. Requires UserAuthentication to be enabled.

  1. Restrict view access to selected users and groups. Set one or both of these settings in its WebPreferences topic:
    • Set DENYWEBVIEW = < list of users and groups >
    • Set ALLOWWEBVIEW = < list of users and groups >
    • Note: DENYWEBVIEW is evaluated before ALLOWWEBVIEW. Access is denied if the authenticated person is in the DENYWEBVIEW list, or not in the ALLOWWEBVIEW list. Access is granted if DENYWEBVIEW and ALLOWWEBVIEW are not defined.

Hide control settings

TIP To hide access control settings from normal browser viewing, you can put them into the topic preference settings by clicking the link Edit topic preference settings under More topic actions menu. Preferences set in this manner are not visible in the topic text, but take effect nevertheless. Access control settings added as topic preference settings are stored in the topic meta data and they override settings defined in the topic text.

Alternatively, place them in HTML comment markers, but this exposes the access setting during ordinary editing.

<!--
   * Set DENYTOPICCHANGE = Main.SomeGroup

Text Formatting

Working in Foswiki is as easy as typing in text. You don't need to know HTML, though you can use it if you prefer. Links to topics are created automatically when you enter WikiWords. And Foswiki shorthand gives you all the power of HTML with a simple coding system that takes no time to learn. It's all laid out below.

Editing Shorthand

Formatting Command: You write: You get:
Paragraphs:
Blank lines will create new paragraphs.
1st paragraph

2nd paragraph

1st paragraph

2nd paragraph

Headings:
Three or more dashes at the beginning of a line, followed by plus signs and the heading text. One plus creates a top level heading, two pluses a second level heading, etc. The maximum heading depth is 6.

You can create a table of contents with the %TOC% macro. If you want to exclude a heading from the TOC, put !! after the ---+.

ALERT! Empty headings are allowed, but won't appear in the table of contents.

---++ Sushi
---+++ Maguro

Verbatim (Literal) Text:
Surround code excerpts and other formatted text with <verbatim> and </verbatim> tags.

TIP verbatim tags disable HTML code. Use <pre> and </pre> tags instead if you want the HTML code within the tags to be interpreted.

ALERT! Preferences settings (* Set NAME = value) are set within verbatim tags.

Table:
Each row of the table is a line containing of one or more cells. Each cell starts and ends with a vertical bar '|'. Any spaces at the beginning of a line are ignored.
  • | *bold* | header cell with text in asterisks
  • |   center-aligned   | cell with at least two, and equal number of spaces on either side
  • |      right-aligned | cell with more spaces on the left
  • | 2 colspan || and multi-span columns with multiple |'s right next to each other
  • |^| cell with caret indicating follow-up row of multi-span rows
  • You can split rows over multiple lines by putting a backslash '\' at the end of each line
  • Contents of table cells wrap automatically as determined by the browser
  • Use %VBAR% or &#124; to add | characters in tables.
  • Use %CARET% or &#94; to add ^ characters in tables.

WikiWord Links:
CapitalizedWordsStuckTogether (or WikiWords) will produce a link automatically if preceded by whitespace or parenthesis.
TIP If you want to link to a topic in a different web write Otherweb.TopicName.
To link to a topic in a subweb write Otherweb.Subweb.TopicName.
HELP The link label excludes the name of the web, e.g. only the topic name is shown. As an exception, the name of the web is shown for the WebHome topic.
ALERT! Dots '.' are used to separate webs and subwebs from topic names and therefore cannot be used in topic names.

It's generally a good idea to use the macros %SYSTEMWEB% and %USERSWEB% instead of System and Main.

Anchors:
You can define a reference inside a topic (called an anchor name) and link to that. To define an anchor write #AnchorName at the beginning of a line. The anchor name must be a WikiWord of no more than 32 characters. To link to an anchor name use the [[MyTopic#MyAnchor]] syntax. You can omit the topic name if you want to link within the same topic.
[[WikiWord#NotThere]]

[[#MyAnchor][Jump]]

#MyAnchor To here

WikiWord#NotThere

Jump

To here

Forced Links:
You can create a forced internal link by enclosing words in double square brackets.
Text within the brackets may contain optional spaces; the topic name is formed by capitalizing the initial letter and by removing the spaces; for example, [[wiki syntax]] links to topic WikiSyntax. You can also refer to a different web and use anchors.
TIP To "escape" double square brackets that would otherwise make a link, prefix the leading left square bracket with an exclamation point.
[[wiki syntax]]

[[Sandbox.My unspaced topic]]

escaped:
![[wiki syntax]]

Main.Wiki groups

escaped: [[wiki syntax]]

Specific Links:
You can create a link where you specify the link text and the URL separately using nested square brackets [[reference][text]]. Internal link references (e.g. WikiSyntax) and URLs (e.g. http://foswiki.org/) are both supported. The rules described under Forced Links apply for internal link references.
TIP Anchor names can be added as well, to create a link to a specific place in a topic.

Literal content:
Foswiki generates HTML code from TML shorthand. Experts surround anything that must be output literally in the HTML code, without the application of shorthand rules, with <literal>..</literal> tags. ALERT! any HTML within literal tags must be well formed i.e. all tags must be properly closed before the end of the literal block. IDEA! Macros are expanded within literal blocks.
<literal>
| Not | A | Table |
</literal>
| Not | A | Table |
Protected content:
Experts protect text from mangling by WYSIWYG editors using <sticky>..</sticky> tags. Sticky tags don't have any effect on normal topic display; they are only relevant when content has to be protected from a WYSIWYG editor (usually because it isn't well-formed HTML, or because it is HTML that WYSIWYG would normally filter out or modify). Protected content appears as plain text in the WYSIWYG editor.
<sticky>
<div>
This div is required
</div>
</sticky>

This div is required

Using HTML

You can use most HTML tags in topics without a problem. This is useful where you want to add some content that is formatted in a way that is not supported using shorthand, for example, you can write <strike>deleted text</strike> to get deleted text.

There are a few usability and technical considerations to keep in mind:

  • On collaboration pages, it's better not to use HTML, but to use shorthand instead - this keeps the text uncluttered and easy to edit using the plaintext editor.
  • If you must use HTML, use XHTML 1.0 Transitional syntax.
  • Use <literal>..</literal> tags around blocks of HTML to avoid accidental interpretation of shorthand within the HTML.
  • ALERT! Script tags may be filtered out, at the discretion of your Wiki administrator.

Recommendations when pasting HTML from other sources (using the plain-text editor):

  • Copy only text between <body> and </body> tags.
  • Remove all empty lines. Foswiki inserts <p /> paragraph tags on empty lines, which causes problems if done between HTML tags that do not allow paragraph tags, like for example between table tags.
  • Remove leading spaces. Foswiki might interpret some text as lists.
  • Do not span a tag over more than one line. Foswiki requires that the opening and closing angle brackets - <...> - of a HTML tag are on the same line, or the tag will be broken.
  • In your HTML editing program, save without hard line breaks on text wrap.

When using a WYSIWYG editor, you can just copy-paste directly into the editor, and the content will be converted to shorthand automatically when you save.

Hyperlinks

Being able to create links without any special formatting is a core Foswiki feature, made possible with WikiWords and inline URLs.

Internal Links

  • GoodStyle is a WikiWord that links to the GoodStyle topic located in the current web.

  • NotExistingYet is a topic waiting to be written. Create the topic by clicking on the ?. (Try clicking, but then, Cancel - creating the topic would wreck this example!)

External Links

  • Protocols matching the configuration parameter LinkProtocolPattern, which by default is set to (file|ftp|gopher|https|http|irc|mailto|news|nntp|telnet), are linked automatically. You might change this setting to add more protocols (such as smb). Thus, all lines containing:
    • file://...
    • ftp://...
    • gopher://...
    • https://...
    • http://...
    • irc://...
    • mailto:...@...
    • news://...
    • nntp://...
    • telnet://... are linked automatically.

  • E-mail addresses like name@domain.com are linked automatically.

  • [[Square bracket rules]] let you easily create non-WikiWord links.
    • You can also write [[http://yahoo.com Yahoo home page]] as an easier way of doing external links with descriptive text for the link, such as Yahoo home page.

Macros

Macros are names enclosed in percent signs that are that are expanded to some other text when the topic is displayed. For example, %TOPIC% is expanded to MacrosQuickStart, the title of this topic.

Some macros can take arguments in curly braces - for example, %INCLUDE{"OtherTopic" ARG="arg"}%.

Many macro definitions are built-in, and others (preference settings) are predefined for your convenience. You can also define your own preference settings at the entire site, individual web, or individual topic level. For more information, see Macros

Macros are fully expanded before any of the text formatting rules are applied.

Documentation Graphics: There are many graphics available to use in your topics. Use %ICON{"help"}%, %ICON{"tip"}%, and %ICON{"warning"}% to get: HELP, TIP, and ALERT!, respectively. DocumentGraphics lists them all.

tip To "escape" a macro, prefix it with an exclamation mark. Write: !%SOMEMACRO% to get: %SOMEMACRO%.

Common Editing Errors

Foswiki formatting rules are fairly simple to use and quick to type. However, there are some things to watch out for:

  • Q: Text enclosed in angle brackets like <filename> is not displayed. How can I show it as it is?
    • A: The '<' and '>' characters have a special meaning in HTML, they define HTML tags. You need to escape them, so write '&lt;' instead of '<', and '&gt;' instead of '>'.
      Example: Type 'prog &lt;filename&gt;' to get 'prog <filename>'.

  • Q: Why is the '&' character sometimes not displayed?
    • A: The '&' character has a special meaning in HTML, it starts a so called character entity, i.e. '&copy;' is the © copyright character. You need to escape '&' to see it as it is, so write '&amp;' instead of '&'.
      Example: Type 'This &amp; that' to get 'This & that'.

Macros

Special text strings expand on the fly to display user data or system info

Macros are text strings - %MACRONAME% or %MACRONAME{ parameter="value" }% - that expand into content whenever a topic is rendered for viewing. There are two types of macros:

  1. Preference settings: Can be defined and changed by the user
  2. Predefined macros: Defined by the system or by Plugins (for example, the SpreadSheetPlugin introduces a %CALC{}% macro)

Using Macros

To use a macro type its name. For example,

  • type %T% to get TIP (a preference settings)
  • type %TOPIC% to get Macros (a predefined macro?)
  • type %CALC{ "$UPPER(Text)" }% to get TEXT (a macro? defined by a Plugin)

Note:

  • To leave a macro unexpanded, precede it with an exclamation point, e.g. type !%TOPIC% to get %TOPIC%
  • Macros are expanded relative to the topic they are used in, not the topic they are defined in
  • Type %ALLVARIABLES% to get a full listing of all macros defined for a particular topic

Macro Names

Macro names must start with a letter. The following characters can be letters, numbers and the underscore '_'. You can use both upper-case and lower-case letters and you can mix the characters. E.g. %MYVAR%, %MyVar%, %My2ndVar%, and %My_Var% are all valid macro names. Macros are case sensitive. %MyVAR% and %MYVAR% are not the same macro.

By convention all settings, predefined macros and macros used by plugins are always UPPER-CASE.

Preferences

Preferences settings are simple macros that do not accept parameters, and are defined in topics. A lot of the macros you will encounter are of this type.

Preferences can be defined by the user in various places.

Setting Preferences

You can set macros in all the following places:
  1. default level in System.DefaultPreferences (not recommended)
  2. plugin topics (see Plugins)
  3. local site level in Main.SitePreferences
  4. user level in individual user topics in Main web
  5. web level in WebPreferences of a parent web
  6. web level in WebPreferences of the web
  7. topic level in topics in webs
  8. session macros (if sessions are enabled)

Settings at higher-numbered levels override settings of the same macro at lower numbered levels, unless the macro was included in the setting of FINALPREFERENCES at a lower-numbered level, in which case it is locked at the value it has at that level.

If you are setting a preference and using it in the same topic, note that Foswiki reads all the preference settings from the saved version of the topic before it displays anything. This means you can use a macro anywhere in the topic, even if you set it somewhere inconspicuous near the end. But beware: it also means that if you change the setting of a macro you are using in the same topic, Preview will show the wrong thing, and you must Save the topic to see it correctly.

The syntax for setting macros is the same anywhere:
[multiple of 3 spaces] * [space] Set [space] MACRONAME [space] = [space] value

Examples:
  • Set MACRONAME = value
    • Set MACRONAME = value
Spaces between the = sign and the value will be ignored. You can split a value over several lines by indenting following lines with spaces - as long as you don't try to use * as the first character on the following line.
Example:
   * Set MACRONAME = value starts here
     and continues here

Whatever you include in your Macro will be expanded on display, exactly as if it had been entered directly.

Example: Create a custom logo macro
  • To place a logo anywhere in a web by typing %MYLOGO%, define the preference settings on the web's WebPreferences topic, and upload a logo file, ex: mylogo.gif. You can upload by attaching the file to WebPreferences, or, to avoid clutter, to any other topic in the same web, e.g. LogoTopic. Sample preference setting in WebPreferences:
    • Set MYLOGO = %PUBURL%/%WEB%/LogoTopic/mylogo.gif

You can also set preference settings in a topic by clicking the link Edit topic preference settings under More topic actions. Preferences set in this manner are not visible in the topic text, but take effect nevertheless.

Access Control Settings

These are special types of preference settings to control access to content. AccessControl explains these security settings in detail.

Local values for preferences

Certain topics (a users home topic, web site and default preferences topics) have a problem; macros defined in those topics can have two meanings. For example, consider a user topic. A user may want to use a double-height edit box when they are editing their home topic - but only when editing their home topic. The rest of the time, they want to have a normal edit box. This separation is achieved using Local in place of Set in the macro definition. For example, if the user sets the following in their home topic:
   * Set EDITBOXHEIGHT = 10
   * Local EDITBOXHEIGHT = 20
Then when they are editing any other topic, they will get a 10 high edit box. However when they are editing their home topic, they will get a 20 high edit box. Local can be used wherever a preference needs to take a different value depending on where the current operation is being performed.

Use this powerful feature with great care! %ALLVARIABLES% can be used to get a listing of the values of all macros in their evaluation order, so you can see macro scope if you get confused.

Predefined Macros

Most predefined macros return values that were either set in the configuration when Foswiki was installed, or taken from server info (such as current username, or date and time). Some, like %SEARCH%, are powerful and general tools.

  • ALERT! Predefined macros can be overridden by preference settings (except TOPIC and WEB)
  • ALERT! Plugins may extend the set of predefined macros (see individual Plugins topics for details)
  • TIP Take the time to thoroughly read through ALL preference macros. If you actively configure your site, review macros periodically. They cover a wide range of functions, and it can be easy to miss the one perfect macro for something you have in mind. For example, see %BASETOPIC%, %INCLUDE%, and the mighty %SEARCH%.

This version of Foswiki - Foswiki-1.0.9, Sun, 17 Jan 2010, build 6075 - predefines the following macros:

    • all non-printable ASCII characters below space, except newline ("\n") and linefeed ("\r")
    • HTML special characters "<", ">", "&", single quote (') and double quote (")
    • TML special characters "%", "[", "]", "@", "_", "*", "=" and "|"
  • Syntax: %ENCODE{"string"}%
  • Supported parameters:
    Parameter: Description: Default:
    "string" String to encode required (can be empty)
    type="entity"
    type="safe"
    type="html"
    type="quotes"
    type="url"
    Control how special characters are encoded
    entity: Encode special characters into HTML entities, like a double quote into &#034;. Does not encode \n or \r.
    safe: Encode characters '"<>% into HTML entities.
    html: As type="entity" except it also encodes \n and \r
    quotes: Escape double quotes with backslashes (\"), does not change other characters
    url: Encode special characters for URL parameter use, like a double quote into %22 (this is the default)
    type="url"
  • Example: %ENCODE{"spaced name"}% expands to spaced%20name
  • ALERT! Values of HTML input fields must be entity encoded.
    Example: <input type="text" name="address" value="%ENCODE{ "any text" type="entity" }%" />
  • ALERT! Double quotes in strings must be escaped when passed into other macros.
    Example: %SEARCH{ "%ENCODE{ "string with "quotes"" type="quotes" }%" noheader="on" }%
  • ALERT! ENCODE can be used to filter user input from URL parameters and similer to protect against cross-site scripting. The safest approach is to use type="entity". This can however prevent an application from fully working. You can then use type="safe" which encodes only the characters '"<>% into HTML entities (same as encode="safe"). When ENCODE is passing a string inside another macro always use double quotes ("") type="quote". For maximum security against cross-site scripting you are adviced to install the Foswiki:Extensions.SafeWikiPlugin.

ENDCOLOR -- end colored text

ENDSECTION{"name"} -- marks the end of a named section within a topic

  • Syntax: %ENDSECTION{"name"}%

  • If the STARTSECTION is named, the corresponding ENDSECTION must also be named with the same name. If the STARTSECTION specifies a type, then the corresponding ENDSECTION must also specify the same type. If the section is unnamed, ENDSECTION will match with the nearest unnamed %STARTSECTION% of the same type above it.
  • Related: STARTSECTION

ENV{"varname"} -- inspect the value of an environment variable

  • Returns the current value of the environment variable in the CGI (Common Gateway Interface) environment. This is the environment that the CommandAndCGIScripts are running in.
  • Note: For security reasons, only those environment variables whose names match the regular expression in {AccessibleENV} in the Security Settings/Miscellaneous section of configure can be displayed. Any other variable will just be shown as an empty string, irrespective of its real value.
  • Example: %ENV{MOD_PERL}% displays as: not set
  • If an environment variable is undefined (as against being set to the empty string) it will be returned as not set.
  • Related: HTTP_HOST, REMOTE_ADDR, REMOTE_PORT, REMOTE_USER

      Did you want to reset Main.WikiGuest's password?
  • Notes:
    • Foswiki will translate the string to the current user's language only if it has such string in its translation table for that language.
    • Amperstands (&) followed by one letter (one of a...z, A...Z) (say, X) in the translatable string will be translated to <span class='foswikiAccessKey'>X</span>. This is used to implement access keys. If you want to write an actual amperstand that stays just before a letter, write two consecutive amperstands (&&): they will be transformed in just one.
    • translatable string starting with underscores (_) are reserved. You cannot use translatable phrases starting with an underscore.
    • Make sure that the translatable string is constant. Specially, do not include %MACROS% inside the translatable strings (since they will get expanded before the %MAKETEXT{...}% itself is handled).

    format="..." Format string for each entry $name=$value
    separator="..." Separator string separator="$n" (newline)
    encoding="entity"
    encoding="safe"
    encoding="html"
    encoding="quotes"
    encoding="url"
    Control how special characters are encoded. If this parameter is not given, "safe" encoding is performed which HTML entity encodes the characters '"<>%.
    entity: Encode special characters into HTML entities, like a double quote into &#034;. Does not encode \n or \r.
    safe: Encode characters '"<>% into HTML entities. (this is the default)
    html: As type="entity" except it also encodes \n and \r
    quotes: Escape double quotes with backslashes (\"), does not change other characters
    url: Encode special characters for URL parameter use, like a double quote into %22
    type="safe"
  • The following escape sequences are expanded in the format string:
    Sequence: Expands To:
    $name Name of the parameter
    $value String value of the parameter. Multi-valued parameters will have a "row" for each value.
    $n or $n() New line. Use $n() if followed by alphanumeric character, e.g. write Foo$n()Bar instead of Foo$nBar
    $nop or $nop() Is a "no operation". This token gets removed; useful for nested search
    $quot Double quote (") (\" also works)
    $percnt Percent sign (%)
    $dollar Dollar sign ($)
    $lt Less than sign (<)
    $gt Greater than sign (>)
    $amp Ampersand (&)
  • Example:
    • %QUERYPARAMS{format="<input type='hidden' name='$name' value='$value' encoding="entity" />"}%
  • ALERT! Security warning!
    Using QUERYPARAMS can easily be misused for cross-site scripting unless specific characters are entity encoded. By default QUERYPARAMS encodes the characters '"<>% into HTML entities (same as encoding="safe") which is relatively safe. The safest is to use encoding="entity". When passing QUERYPARAMS inside another macro always use double quotes ("") combined with using QUERYPARAMS with encoding="quote". For maximum security against cross-site scripting you are adviced to install the Foswiki:Extensions.SafeWikiPlugin.
  • See also QUERYSTRING, URLPARAM

QUERYSTRING -- full, unprocessed string of parameters to this URL

  • String of all the URL parameters that were on the URL used to get to the current page. For example, if you add ?name=Samantha;age=24;eyes=blue to this URL you can see this in action. This string can be appended to a URL to pass parameter values on to another page.
  • ALERT! URLs built this way are typically restricted in length, typically to 2048 characters. If you need more space than this, you will need to use an HTML form and %QUERYPARAMS%.
  • Syntax: %QUERYSTRING%

    web="Main, Know"
    web="all"
    Comma-separated list of webs to search. You can specifically exclude webs from an all search using a minus sign - for example, web="all,-Secretweb". The special word all means all webs that do not have the NOSEARCHALL preference set to on in their WebPreferences. Note that AccessControls are respected when searching webs; it is much better to use them than NOSEARCHALL. Current web
    topic="WebPreferences"
    topic="*Bug"
    Limit search to topics: A topic, a topic with asterisk wildcards, or a list of topics separated by comma. Note this is a list of topic names and must not include web names. All topics in a web

    type="regex"
    type="query"
    Control how the search is performed when scope="text" or scope="all"
    keyword: use Google-like controls as in soap "web service" -shampoo; searches word parts: using the example, topics with "soapsuds" will be found as well, but topics with "shampoos" will be excluded
    word: identical to keyword but searches whole words: topics with "soapsuds" will not be found, and topics with "shampoos" will not be excluded
    literal: search for the exact string, like web service
    regex: use a RegularExpression search like soap;web service;!shampoo; to search on whole words use \bsoap\b
    query: query search of form fields and other meta-data, like (Firstname='Emma' OR Firstname='John') AND Lastname='Peel'
    %SEARCHVAR- DEFAULTTYPE% preferences setting (literal)
    order="topic"
    order="created"
    order="modified"
    order="editby"
    order=
     "formfield(name)"
    Sort the results of search by the topic names, topic creation time, last modified time, last editor's WikiName, or named field of DataForms. The sorting is done web by web; if you want to sort across webs, create a formatted table and sort it with TablePlugin's initsort. Note that dates are sorted most recent date last (i.e at the bottom of the table). Sort by topic name
    limit="all"
    limit="16"
    Limit the number of topics from which results will be returned. This is done after sorting if order is specified. Note that this does not limit the number of hits from the same topic when you have multiple="on". All results

    nosummary="on" Show topic title only Show topic summary
    nosearch="on" Suppress search string Show search string
    noheader="on" Suppress default search header
    Topics: Changed: By: , unless a header is explicitly specified
    Show default search header, unless search is inline and a format is specified (Cairo compatibility)
    nototal="on" Do not show number of topics found Show number
    zeroresults="off" Suppress all output if there are no hits zeroresults="on", displays: "Number of topics: 0"

    multiple="on" Multiple hits per topic. Each hit can be formatted. The last token is used in case of a regular expression ";" and search Only one hit per topic
    nofinalnewline="on" If on, the search variable does not end in a line by itself. Any text continuing immediately after the SEARCH macro on the same line will be rendered as part of the table generated by the search, if appropriate. off
    recurse="on" Recurse into subwebs, if subwebs are enabled. off
    separator=", " Line separator between search hits "$n" (Newline)
    newline="%BR%" Line separator within a search hit. Useful if you want to put multi-line content into a table cell, for example if the format="" parameter contains a $pattern() that captures more than one line, or contains a $formfield() that returns a multi-line textfield. "$n" (Newline)
  • Example: %SEARCH{"wiki" web="Main" scope="topic"}%
  • Example with format: %SEARCH{"FAQ" scope="topic" nosearch="on" nototal="on" header="| *Topic: * | *Summary: * |" format="| $topic | $summary |"}% (displays results in a table with header - details)
  • TIP If the Foswiki:Extensions.TablePlugin is installed, you may put a %TABLE{}% macro just before the %SEARCH{}% to alter the output of a search. Example: %TABLE{ tablewidth="90%" }%

    safe: Encode characters '"<>% into HTML entities.
    url: Encode special characters for URL parameter use, like a double quote into %22
    quote: Escape double quotes with backslashes (\"), does not change other characters; required when feeding URL parameters into other macros.
    "safe"
    multiple="on"
    multiple="[[$item]]"
    If set, gets all selected elements of a <select multiple="multiple"> tag. A format can be specified, with $item indicating the element, e.g. multiple="Option: $item" first element
    separator=", " Separator between multiple selections. Only relevant if multiple is specified "\n" (new line)
  • Example: %URLPARAM{"skin"}% returns print for a .../view/System/Macros?skin=print URL
  • ALERT! Notes:
    • URL parameters passed into HTML form fields must be entity ENCODEd.
    • Double quotes in URL parameters must be escaped when passed into other macros.
      Example: %SEARCH{ "%URLPARAM{ "search" encode="quote" }%" noheader="on" }%
    • When used in a template topic, this macro will be expanded when the template is used to create a new topic. See TemplateTopics#TemplateTopicsVars for details.
    • Watch out for internal parameters, such as rev, skin, template, topic, web; they have a special meaning in Foswiki. Common parameters and view script specific parameters are documented at CommandAndCGIScripts.
    • If you have %URLPARAM{ in the value of a URL parameter, it will be modified to %<nop>URLPARAM{. This is to prevent an infinite loop during expansion.
    • Security warning! Using URLPARAM can easily be misused for cross-site scripting unless specific characters are entity encoded. By default URLPARAM encodes the characters '"<>% into HTML entities (same as encode="safe") which is relatively safe. The safest is to use encode="entity". When passing URLPARAM inside another macro always use double quotes ("") combined with using URLPARAM with encode="quote". For maximum security against cross-site scripting you are adviced to install the Foswiki:Extensions.SafeWikiPlugin.

    Name Description Example
    id The identifier of the poll. You can have multiple independent votes in the same topic. id="Dining"
    selectN Defines the name of a select vote, where you select one from a ranges of options. N is a number that identifies this item within the poll e.g. select1, select2 etc. You must number all select and stars parameters uniquely and sequentially (e.g. select1 stars2 select3 select1="Drink"
    optionsN Each selectN must have a corresponding optionsN that defines a comma-separated list of the options that can be selected between. options1="Beer,Wine,Milk"
    starsN Defines the name of a rate vote, where you rate something by giving it a number of stars. N is a number that identifies this item within the poll e.g. select1, stars2 etc. You must number all select and stars parameters uniquely and sequentially (e.g. select1 stars2 select3 stars2="Usability"
    widthN Each starsN must have a corresponding widthN. This gives the number of stars to show e.g. width1="5" will show 5 stars. width2="10"
    formatN Defines the format of the results display. See formatting results, below. format="$large"
    chartN Defines the format of a single bar in the results bar chart generated for the corresponding select (for select type only). See formatting results, below. chart="<p>$option $score</p>"
    separator Defines the string to be used to separate each row in the result. separator="<br/>"
    global If set to "off", this makes the id local to this topic (the default). If set to "on" it will be a global poll that can be accessed from many topics. global="on"
    open If set to "off" this is a closed vote. If set to "on" it is open (the default) open="on"
    secret If set to "off", then the database will record who voted. If set to "on", votes are secret (the default) secret="on"
    saveto If set to the name of a topic, the poll results will be appended to the end of that topic. The results are formatted as a table for easy post-processing. saveto="Main.VoteResults"
    bayesian If set to "on", rating averages will be computed using the Bayesian average of this item against all the other items that have the same item in their stars field. This requires all the participating %VOTEs to be global, or to save their results to the same place using saveto. See http://www.thebroth.com/blog/118/bayesian-rating for more information about Bayesian rating. bayesian="off"
    submit If set to "off", this makes the %VOTE display the results of the vote without prompting for any input. This is useful when - for example - you want to show the results of a global vote, without permitting more voting.

WEB -- name of current web

  • %WEB% expands to the name of the web where the topic is located. If you are looking at the text of an included topic, it is the web where the included topic is located.
  • Syntax: %WEB%
  • Expands to: System
  • Related: BASEWEB, INCLUDINGWEB, TOPIC

WEBLIST{"format"} -- index of all webs

  • List of all webs. Obfusticated webs are excluded, e.g. webs with a NOSEARCHALL = on preference setting. The "format" defines the format of one web item. The $name gets expanded to the name of the web, $qname gets expanded to double quoted name, $marker to marker where web matches selection.
  • Syntax: %WEBLIST{"format" ...}%
  • Supported parameters:
    Parameter: Description: Default:
    "format" Format of one line, may include $name (the name of the web), $qname (the name of the web in double quotes), $indentedname (the name of the web with parent web names replaced by indents, for use in indented lists), and $marker (which expands to marker for the item matching selection only) "$name"
    format="format" (Alternative to above) "$name"
    separator=", " Line separator "$n" (new line)
    web="" if you specify $web in format, it will be replaced with this ""
    webs="public" Comma separated list of webs, public expands to all non-hidden.
    NOTE: Administrators will see all webs, not just the public ones
    "public"
    marker="selected" Text for $marker if the item matches selection "selected"
    selection="%WEB%" Current value to be selected in list selection="%WEB%"
    subwebs="Sandbox" show webs that are a sub-web of this one (recursivly) ""
  • Example: %WEBLIST{"   * [[$name.WebHome]]"}% - creates a bullet list of all webs.
  • Example: <form><select name="web"> %WEBLIST{"<option $marker value=$qname>$name</option>" webs="Trash, public" selection="%WEB%" separator=" "}% </select></form> - creates a dropdown of all public webs + Trash web, with the current web highlighted.
  • ALERT! - WEBLIST will not show a web called 'TWiki' even if it exists in the file system unless the TWikiCompatibilityPlugin is installed and activated in configure. This is done to ensure that the TWiki compatibility components such as the TWiki web are only visible and active when needed.

Formatted Search

Inline search feature allows flexible formatting of search result

The default output format of a %SEARCH{...}% is a table consisting of topic names and topic summaries. Use the format="..." parameter to customize the search result. The format parameter typically defines a bullet or a table row containing macros, such as %SEARCH{ "food" format="| $topic | $summary |" }%. See %SEARCH{...}% for other search parameters, such as separator="".

Syntax

Two parameters can be used to specify a customized search result:

1. header="..." parameter

Use the header parameter to specify the header of a search result. It should correspond to the format of the format parameter. This parameter is optional.
Example: header="| *Topic:* | *Summary:* |"

Format tokens that can be used in the header string:

Name: Expands To:
$web Name of the web
$n or $n() New line. Use $n() if followed by alphanumeric character, e.g. write Foo$n()Bar instead of Foo$nBar
$nop or $nop() Is a "no operation". This token gets removed; useful for nested search
$quot Double quote (") (\" also works)
$percnt Percent sign (%)
$dollar Dollar sign ($)
$lt Less than sign (<)
$gt Greater than sign (>)
$amp Ampersand (&)

2. footer="..." parameter

Use the footer parameter to specify the footer of a search result. It should correspond to the format of the format parameter. This parameter is optional.
Example: footer="| *Topic* | *Summary* |"

Format tokens that can be used in the footer string:

Name: Expands To:
$web Name of the web
$ntopics Number of topics found in current web
$nhits Number of hits if multiple="on". Cumulative across all topics in current web. Identical to $ntopics unless multiple="on"
$n or $n() New line. Use $n() if followed by alphanumeric character, e.g. write Foo$n()Bar instead of Foo$nBar
$nop or $nop() Is a "no operation". This token gets removed; useful for nested search
$quot Double quote (") (\" also works)
$percnt Percent sign (%)
$dollar Dollar sign ($)
$lt Less than sign (<)
$gt Greater than sign (>)
$amp Ampersand (&)

3. format="..." parameter

Use the format parameter to specify the format of one search hit.
Example: format="| $topic | $summary |"

Format tokens that can be used in the format string:

Name: Expands To:
$web Name of the web
$topic Topic name
$topic(20) Topic name, "- " hyphenated each 20 characters
$topic(30, -<br />) Topic name, hyphenated each 30 characters with separator "-<br />"
$topic(40, ...) Topic name, shortended to 40 characters with "..." indication
$parent Name of parent topic; empty if not set
$parent(20) Name of parent topic, same hyphenation/shortening like $topic()
$text Formatted topic text. In case of a multiple="on" search, it is the line found for each search hit.
$locked LOCKED flag (if any)
$date Time stamp of last topic update, e.g. 19 Mar 2024 - 04:10
$isodate Time stamp of last topic update, e.g. 2024-03-19T04:10Z
$rev Number of last topic revision, e.g. 4
$username Login name of last topic update, e.g. jsmith
$wikiname Wiki user name of last topic update, e.g. JohnSmith
$wikiusername Wiki user name of last topic update, like Main.JohnSmith
$createdate Time stamp of topic revision 1
$createusername Login name of topic revision 1, e.g. jsmith
$createwikiname Wiki user name of topic revision 1, e.g. JohnSmith
$createwikiusername Wiki user name of topic revision 1, e.g. Main.JohnSmith
$summary Topic summary, just the plain text, all formatting and line breaks removed; up to 162 characters
$summary(50) Topic summary, up to 50 characters shown
$summary(showvarnames) Topic summary, with %SOMEMACRO{...}% macros shown as SOMEMACRO{...}
$summary(noheader) Topic summary, with leading ---+ headers removed
Note: The tokens can be combined, for example $summary(100, showvarnames, noheader)
$changes Summary of changes between latest rev and previous rev
$changes(n) Summary of changes between latest rev and rev n
$formname The name of the form attached to the topic; empty if none
$formfield(name) The field value of a form field; for example, $formfield(TopicClassification) would get expanded to PublicFAQ. This applies only to topics that have a DataForm
$formfield(name, 10) Form field value, "- " hyphenated each 10 characters
$formfield(name, 20, -<br />) Form field value, hyphenated each 20 characters with separator "-<br />"
$formfield(name, 30, ...) Form field value, shortended to 30 characters with "..." indication
$pattern(reg-exp) A regular expression pattern to extract some text from a topic (does not search meta data; use $formfield instead). In case of a multiple="on" search, the pattern is applied to the line found in each search hit.
• Specify a RegularExpression that covers the whole text (topic or line), which typically starts with .*, and must end in .*
• Put text you want to keep in parenthesis, like $pattern(.*?(from here.*?to here).*)
• Example: $pattern(.*?\*.*?Email\:\s*([^\n\r]+).*) extracts the e-mail address from a bullet of format * Email: ...
• This example has non-greedy .*? patterns to scan for the first occurance of the Email bullet; use greedy .* patterns to scan for the last occurance
• Limitation: Do not use .*) inside the pattern, e.g. $pattern(.*foo(.*)bar.*) does not work, but $pattern(.*foo(.*?)bar.*) does
• Note: Make sure that the integrity of a web page is not compromised; for example, if you include an HTML table make sure to include everything including the table end tag
$count(reg-exp) Count of number of times a regular expression pattern appears in the text of a topic (does not search meta data). Follows guidelines for use and limitations outlined above under $pattern(reg-exp). Example: $count(.*?(---[+][+][+][+]) .*) counts the number of <H4> headers in a page.
$ntopics Number of topics found in current web. This is the current topic count, not the total number of topics
$nhits Number of hits if multiple="on". Cumulative across all topics in current web. Identical to $ntopics unless multiple="on"
$n or $n() New line. Use $n() if followed by alphanumeric character, e.g. write Foo$n()Bar instead of Foo$nBar
$nop or $nop() Is a "no operation". This token gets removed; useful for nested search
$quot Double quote (") (\" also works)
$percnt Percent sign (%)
$dollar Dollar sign ($)
$lt Less than sign (<)
$gt Greater than sign (>)
$amp Ampersand (&)

Examples

Here are some samples of formatted searches. The SearchPatternCookbook has other examples, such as creating a picklist of usernames, searching for topic children and more.

Bullet list showing topic name and summary

Write this:

%SEARCH{ "VarREMOTE" scope="topic" nosearch="on" nototal="on" header="| *Topic* | *Summary* |" format="| [[$topic]] | $summary |"  footer="| *Topics found* | *$ntopics* |"  }%

To get this:

Topic Summary
VarREMOTEADDR #VarREMOTEADDR REMOTE ADDR environment variable Syntax: % nop REMOTE ADDR% Expands to: Related: ENV, HTTP HOST, REMOTE PORT, REMOTE USER
VarREMOTEPORT #VarREMOTEPORT REMOTE PORT environment variable Syntax: % nop REMOTE PORT% Expands to: Related: ENV, HTTP HOST, REMOTE ADDR, REMOTE USER
VarREMOTEUSER #VarREMOTEUSER REMOTE USER environment variable Syntax: % nop REMOTE USER% Expands to: Related: ENV, HTTP HOST, REMOTE ADDR, REMOTE PORT, USERNAME ...

Table showing form field values of topics with a form

In a web where there is a form that contains a TopicClassification field, an OperatingSystem field and an OsVersion field we could write:

| *Topic:* | *OperatingSystem:* | *OsVersion:* |
%SEARCH{ "[T]opicClassification.*?value=\"[P]ublicFAQ\"" scope="text" type="regex" nosearch="on" nototal="on" format="| [[$topic]] | $formfield(OperatingSystem) | $formfield(OsVersion) |" }%

Nested Search

Search can be nested. For example, search for some topics, then form a new search for each topic found in the first search. The idea is to build the nested search string using a formatted search in the first search.

Here is an example. Let's search for all topics that contain the word "culture" (first search), and let's find out where each topic found is linked from (second search).

  • First search:
    • %SEARCH{ "culture" format="   * $topic is referenced by: (list all references)" nosearch="on" nototal="on" }%
  • Second search. For each hit we want this search:
    • %SEARCH{ "(topic found in first search)" format="$topic" nosearch="on" nototal="on" separator=", " }%
  • Now let's nest the two. We need to escape the second search, e.g. the first search will build a valid second search string. Note that we escape the second search so that it does not get evaluated prematurely by the first search:
    • Use $percnt to escape the leading percent of the second search
    • Use \" to escape the double quotes
    • Use $dollar to escape the $ of $topic
    • Use $nop to escape the }% sequence

Write this:

%SEARCH{ "culture" format="   * $topic is referenced by:$n      * $percntSEARCH{ \"$topic\" format=\"$dollartopic\" nosearch=\"on\" nototal=\"on\" separator=\", \" }$nop%" nosearch="on" nototal="on" }%

Note: Nested search can be slow, especially if you nest more then 3 times. Nesting is limited to 16 levels. For each new nesting level you need to "escape the escapes", e.g. write $dollarpercntSEARCH{ for level three, $dollardollarpercntSEARCH{ for level four, etc.

Most recently changed pages

Write this:

%SEARCH{ "\.*" scope="topic" type="regex" nosearch="on" nototal="on" order="modified" reverse="on"  format="| [[$topic]] | $wikiusername  | $date |" limit="7" }%

Search with conditional output

A regular expression search is flexible, but there are limitations. For example, you cannot show all topics that are up to exactly one week old, or create a report that shows all records with invalid form fields or fields within a certain range, etc. You need some additional logic to format output based on a condition:

  1. Specify a search which returns more hits then you need
  2. For each search hit apply a spreadsheet formula to determine if the hit is needed
  3. If needed, format and output the result
  4. Else supress the search hit

This requires the Foswiki:Extensions.SpreadSheetPlugin. The following example shows all topics that are up to exactly one week old.

Write this:

%CALC{$SET(weekold, $TIMEADD($TIME(), -7, day))}%
%SEARCH{ "." scope="topic" type="regex" nosearch="on" nototal="on" order="modified" reverse="on" format="$percntCALC{$IF($TIME($date) < $GET(weekold), <nop>, | [[$topic]] | $wikiusername | $date | $rev |)}$percnt" limit="100" }%

  • The first line sets the weekold variable to the serialized date of exactly one week ago
  • The SEARCH has a deferred CALC. The $percnt makes sure that the CALC gets executed once for each search hit
  • The CALC compares the date of the topic with the weekold date
  • If topic is older, a <nop> is returned, which gets removed at the end of the rendering process
  • Otherwise, the search hit is formatted and returned

To get this:

Embedding search forms to return a formatted result

Use an HTML form and an embedded formatted search on the same topic. You can link them together with an %URLPARAM{"..."}% macro. Example:

Write this:

<form action="%SCRIPTURLPATH{"view"}%/%WEB%/%TOPIC%">
Find Topics: 
<input type="text" name="q" size="32" value="%URLPARAM{"q" encode="entity"}%" />&nbsp;<input type="submit" class="foswikiSubmit" value="Search" />
</form>
Result:
%SEARCH{ search="%URLPARAM{"q" encode="quote"}%" type="keyword" format="   * $web.$topic: %BR% $summary" nosearch="on" }%

File Attachments

Each topic can have one or more files of any type attached to it by using the Attach screen to upload (or download) files from your local PC. Attachments are stored under revision control: uploads are automatically backed up; all previous versions of a modified file can be retrieved.

What are attachments good for?

File Attachments can be used to archive data, or to create powerful customized groupware solutions, like file sharing and document management systems, and quick Web page authoring.

Document management system

You can use Attachments to store and retrieve documents (in any format, with associated graphics, and other media files); attach documents to topics; collaborate on documents with full revision control; distribute documents on a need-to-know basis using web and topic-level access control; create a central reference library that's easy to share with an user group spread around the world.

File sharing

For file sharing, FileAttachments on a series of topics can be used to quickly create a well-documented, categorized digital download center for all types of files: documents, graphics and other media, drivers and patches, applications; anything you can safely upload!

Web authoring

Through your web browser, you can easily upload graphics (or sound files, or anything else you want to link to on a page) and place them on a single page, or use them across a web, or site-wide.

HELP You can also add graphics - any files - directly, typically by FTP upload. This requires FTP access, and may be more convenient if you have a large number of files to load. FTP-ed files cannot be managed using browser-based attachment controls. You can use your browser to create shortcuts using Macros, like this %H% = HELP.

Uploading files

  • Click on the [Attach] link at the bottom of the page. The Attach screen lets you browse for a file, add a comment, and upload it. The uploaded file will show up in the file attachment table.
    • HELP The topic must already exist. If it does not, it is a two step process: First create the topic, then add the file attachment.
    • Any type of file can be uploaded. Some files that might pose a security risk are renamed, for example: *.php files are renamed to *.php.txt so that no one can place code that would be read in a .php file.
    • Foswiki can limit the file size. This is defined by the %ATTACHFILESIZELIMIT% preference settings, currently set at 25000 kB.
      • ALERT! It is not recommended to upload files greater than a few hundred K through a browser. Large files can be extremely slow-loading, and often time out. Use an FTP site for large file uploads.
  • Automatic attachments:
    • When enabled, all files in a topic's attachment directory are shown as attachments to the topic - even if they were directly copied to the directory and never attached by using an [Attach] link. This is a convenient way to quickly "attach" files to a topic without uploading them one by one; although at the cost of losing audit trail and version control.
    • To enable this feature, set the {AutoAttachPubFiles} configuration option.
    • HELP The automatic attachment feature can only be used by an administrator who has access to the server's file system.

Downloading files

  • ALERT! There is no access control on individual attachments. If you need control over single files, create a separate topic per file and set topic-level access restrictions for each.

Moving attachment files

An attachment can be moved between topics.

  • Click [Manage] on the Attachment to be moved.
  • On the control screen, select the new web and/or topic.
  • Click [Move]. The attachment and its version history are moved. The original location is stored as topic meta data.

Deleting attachments

Move unwanted Attachments to web Trash, topic TrashAttachment.

Linking to attached files

  • Once a file is attached it can be referenced in the topic. Example:
    1. [Attach] a file, for example: Sample.txt
    2. [Edit] the topic you attached the file to and enter: %ATTACHURL%/Sample.txt
    3. [Preview]: the %ATTACHURL%/Sample.txt text appears as: /foswiki/pub/System/FileAttachment/Sample.txt, a link to the text file.

  • To reference an attachment located in another topic, enter:
    • %PUBURLPATH%/%WEB%/OtherTopic/Sample.txt (if it's within the same web)
    • %PUBURLPATH%/Otherweb/OtherTopic/Sample.txt (if it's in a different web)

  • Attached HTML files and text files can be inlined in a topic. Example:
    1. [Attach] file: Sample.txt
    2. [Edit] topic and write text: %INCLUDE{"%ATTACHURL%/Sample.txt"}%

  • GIF, JPG and PNG images can be attached and shown embedded in a topic. Example:
    1. [Attach] an image file, for example: Smile.gif
    2. [Edit] topic and write text: %ATTACHURL%/Smile.gif
    3. [Preview]: text appears as Smile.gif, an image.

Examples

Following you will find some examples of screens and tables related to this topic and referenced throughout the previous text. The appearance of these tables might vary, depending on what skin is used on your Foswiki installation.

File attachment table

Files attached to a topic are displayed in a directory table, showing the different file names and attributes. An h means the attachment is hidden and not listed when viewing a topic in normal mode.

The file attachment table is normally displayed at the bottom of the page, or optionally, hidden and accessed when you click [Attach].

Topic attachments
I Attachment Action Size Date Who Comment
txttxt Sample.txt manage 0.1 K 22 Jul 2000 - 19:37 ProjectContributor Just a sample
gifgif Smile.gif manage 0.1 K 22 Jul 2000 - 19:38 ProjectContributor Smiley face

File attachment controls

Clicking on a [Manage] link takes you to a new page that looks a bit like this (depending on what skin is selected).

Here, you have different options:

  • To update an existing file, choose the updated file on your local drive and click [Update file]. The filename of the original attachment will preserved; the filename of the local file you chose will not be used.
  • To change the comment on an attachment, enter a new comment and then click [Change comment and properties only]. Note that the comment listed against the specific version will not change, however the comment displayed when viewing the topic does change.
  • To hide/unhide an attachment, enable the Do not show attachment in table checkbox, then click [Change comment and properties only].

Attach new file

Select a new local file to update attachment Sample.txt
Upload up to 10000 KB.

Comment

Describe the file so other people know what it is.

Properties

Images will be displayed, for other attachments a link will be created.

Attachments will not be shown in topic view page.

or Cancel

Known Issues

  • Unlike topics, attachments are not locked during editing. As a workaround, you can change the comment to indicate an attachment file is being worked on - the comment on the specific version isn't lost, it's there when you list all versions of the attachment.
  • Attachments are not secured. Anyone can read them if they know the name of the web, topic and attachment.

Data Forms

Data forms allow you to add structured data to topics. The data stored in the form fields can be used to search and filter topics. The combination of structured data and search queries are the base for building database applications.

Overview

By adding form-based input to freeform content, you can structure topics with unlimited, easily searchable categories. A form is enabled for a web and can be added to a topic. The form data is shown in tabular format when the topic is viewed, and can be changed in edit mode using edit fields, radio buttons, check boxes and list boxes. Many different form types can be defined in a web, though a topic can only have one form attached to it at a time.

Typical steps to build an application based on Foswiki forms:

  1. Define a form definition
  2. Enable the form for a web
  3. Build an HTML form to create new topics based on that template topic
  4. Build a FormattedSearch to list topics that share the same form

For a step by step tutorial, see AnApplicationWithWikiForm.

Defining a form

A form definition specifies the fields in a form. A form definition is simply a page containing a Foswiki table, where each row of the table specifies one form field.
  1. Create a new topic with your form name: YourForm, ExpenseReportForm, InfoCategoryForm, RecordReviewForm, whatever you need.
  2. Create a TML table, with each column representing one element of an entry field: Name, Type, Size, Values, Tooltip message, and Attributes (see sample below).
  3. For each field, fill in a new line; for the type of field, select from the list.
  4. Save the topic (you can later choose to enable/disable individual forms).

Example:
| *Name* | *Type* | *Size* | *Values* | *Tooltip message* | *Attributes* |
| TopicClassification | select | 1 | NoDisclosure, PublicSupported, PublicFAQ | blah blah... |   |
| OperatingSystem | checkbox | 3 | OsHPUX, OsLinux, OsSolaris, OsWin | blah blah... |   |
| OsVersion | text | 16 | | blah blah... |   |

Name Type Size Values Tooltip message Attributes
TopicClassification select 1 NoDisclosure, PublicSupported, PublicFAQ blah blah...  
OperatingSystem checkbox 3 OsHPUX, OsLinux, OsSolaris, OsWin blah blah...  
OsVersion text 16   blah blah...  

See structure of a form for full details of what types are available and what all the columns mean.

You can also retrieve possible values for select, checkbox or radio types from other topics:

Example:

  • In the WebForm topic, define the form:
    Name Type Size Values Tooltip message Attributes
    TopicClassification select 1   blah blah...  
    OperatingSystem checkbox 3   blah blah...  
    OsVersion text 16   blah blah...  

    ALERT! Leave the Values field blank.

  • Then in the TopicClassification topic, define the possible values:
    | *Name*            |
    | NoDisclosure      |
    | Public Supported  |
    | Public FAQ        |
    Name
    NoDisclosure
    Public Supported
    Public FAQ

Field values can also be set using the result of expanding other macros. For example,

%SEARCH{"Office$" scope="topic" web="%USERSWEB%" nonoise="on" type="regex" format="$web.$topic" separator=", " }%

When used in the value field of the form definition, this will find all topic names in the Main web which end in "Office" and use them as the legal field values.

Enabling forms by Web

Forms have to be enabled for each individual web. The WEBFORMS setting in WebPreferences is optional and defines a list of possible form definitions.

Example:
  • Set WEBFORMS = BugForm, FeatureForm, Books.BookLoanForm
  • With WEBFORMS enabled, an extra button is added to the edit view. If the topic doesn't have a Form, an Add Form button appears at the end of the topic. If a Form is present, a Change button appears in the top row of the Form. The buttons open a screen that enables selection of a form specified in WEBFORMS, or the No form option.
  • You have to list the available form topics explicitly. You cannot use a SEARCH to define WEBFORMS.

Adding a form to a topic

  • Edit the topic and follow the "Add form" button to add a Form. This is typically done to a template topic, either to the WebTopicEditTemplate topic in a web, or a new topic that serves as an application specific template topic. Initial Form values can be set there.

  • Additionally a new topic can be given a Form using the formtemplate parameter in the (edit or save) URL. Initial values can then be provided in the URLs or as form values:
    • other than checkboxes: name, ex: ?BugPriority=1
    • checkbox: namevalue=1, ex: ?ColorRed=1.
      Boxes with a tick must be specified.
    • Example: This will add a textfield for the new topic name and a "Create"-Button to your topic. When the button is pressed, the topic editor will open with the form "MyForm" already attached to the new topic.
          <form name="newtopic" action="%SCRIPTURLPATH{"edit"}%/%WEB%/">
             <input type="hidden" name="formtemplate" value="MyForm" />
             New topic name <input type="text" name="topic" size="40" />
             <input type="submit" class="foswikiSubmit" value="Create" />
          </form>
             
  • ALERT! Note: You can create a topic in one step, without going through the edit screen. To do that, specify the save script instead of the edit script in the form action. When you specify the save script you must to use the "post" method. Example:
        <form name="newtopic" action="%SCRIPTURLPATH{"save"}%/%WEB%/" method="post">
           .....
        </form>
           
  • HELP The edit and save scripts understand many more parameters, see CommandAndCGIScripts#edit and CommandAndCGIScripts#save for details.

  • ALERT! Note: Initial values will not be set in the form of a new topic if you only use the formtemplate parameter.

Changing a form

  • You can change a form definition, and Foswiki will try to make sure you don't lose any data from the topics that use that form.

  • If you change the form definition, the changes will not take affect in a topic that uses that form until you edit and save it.

  • If you add a new field to the form, then it will appear next time you edit a topic that uses the form.

  • If you delete a field from the form, or change a field name, then the data will not be visible when you edit the topic (the changed form definition will be used). If you save the topic, the old data will be lost (though thanks to revision control, you can always see it in older versions of the topic)

  • If two people edit the same topic containing a form at exactly the same time, and both change fields in the form, Foswiki will try to merge the changes so that no data is lost.

Structure of a form definition

A form definition specifies the fields in a form. A form definition is simply a TML table contained in a topic, where each row of the table specifies one form field.

Each column of the table is one element of an entry field: Name, Type, Size, Values, Tooltip message, and Attributes.

The Name, Type and Size columns are required. Other columns are optional. The form must have a header row (e.g. | *Name* | *Type* | *Size* |).

Name is the name of the form field.

The Type, Size and Value fields describe the legal values for this field, and how to display them.

  • Type checkbox specifies one or more checkboxes. The Size field specifies how many checkboxes will be displayed on each line. The Value field should be a comma-separated list of item labels.
    • Type checkbox+buttons will add Set and Clear buttons to the basic checkbox type.
  • Type radio is like checkbox except that radio buttons are mutually exclusive; only one can be selected.
  • Type label specifies read-only label text. The Value field should contain the text of the label.
  • Type select specifies a select box. The Value field should contain a comma-separated list of options for the box. The Size field can specify a fixed size for the box (e.g. 1, or a range e.g. 3..10. If you specify a range, then the box will never be smaller than 3 items, never larger than 10, and will be 5 high if there are only 5 options.
    • There are two modifiers that can be applied to the select type:
      • select+multi turns multiselect on for the select, to allow Shift+Click and Ctrl+Click to select (or deselect) multiple items.
      • select+values allows the definition of values that are different to the displayed text. For example:
        | Field 9 | select+values | 5 | One, Two=2, Three=III, Four | Various values formats |
        shows but the values or options Two and Three are 2 and III respectively.
        You can combine these modifiers e.g. select+multi+values
  • Type text specifies a one-line text field. Size specifies the text box width in number of characters. Value is the initial (default) content when a new topic is created with this form definition.
  • Type textarea specifies a multi-line text box. The Size field should specify columns x rows, e.g. 80x6; default size is 40x5. As for text, the Value field specifies the initial text
  • Type date specifies a single-line text box and a button next to it; clicking on the button will bring up a calendar from which the user can select a date. The date can also be typed into the text box. Size specifies the text box width in characters. As for text, the Value field specifies the initial text

Tooltip message is a message that will be displayed when the cursor is hovered over the field in edit view.

Attributes specifies special attributes for the field. Multiple attributes can be entered, separated by spaces.

  • An attribute H indicates that this field should not be shown in view mode. However, the field is available for editing and storing information.
  • An attribute M indicates that this field is mandatory. The topic cannot be saved unless a value is provided for this field. If the field is found empty during topic save, an error is raised and the user is redirected to an oops page. Mandatory fields are indicated by an asterisks next to the field name.

For example, a simple form just supporting entry of a name and a date would look as follows:

| *Name* | *Type* | *Size* |
| Name   | text   | 80     |
| Date   | date   | 30     |
Field Name Notes:
  • Field names have to be unique.
  • A very few field names are reserved. If you try to use one of these names, Foswiki will automatically append an underscore to the name when the form is used.
  • You can space out the title of the field, and it will still find the topic e.g. Aeroplane Manufacturers is equivalent to AeroplaneManufacturers.
  • If a label field has no name, it will not be shown when the form is viewed, only when it is edited.
  • Field names can in theory include any text, but you should stick to alphanumeric characters. If you want to use a non-wikiname for a select, checkbox or radio field, and want to get the values from another topic, you can use [[...]] links. This notation can also be used when referencing another topic to obtain field values, but a name other than the topic name is required as the name of the field.
  • Leading and trailing spaces are not significant.
Field Value Notes:
  • The field value will be used to initialize a field when a form is created, unless specific values are given by the topic template or query parameters. The first item in the list for a select or radio type is the default item. For label, text, and textarea fields the value may also contain commas. checkbox fields cannot be initialized through the form definition.
  • Leading and trailing spaces are not significant.
  • Field values can also be generated through a System.FormattedSearch, which must yield a suitable table as the result.
  • Macros in the initial values of a form definition get expanded when the form definition is loaded.
    • If you want to use a | character in the initial values field, you have to precede it with a backslash, thus: \|.
    • You can use <nop> to prevent macros from being expanded.
    • The FormatTokens can be used to prevent expansion of other characters.
General Notes:
  • The topic definition is not read when a topic is viewed.
  • Form definition topics can be protected in the usual manner, using AccessControl, to limit who can change the form definition and/or individual value lists. Note that view access is required to be able to edit topics that use the form definition, though view access to the form definition is not required to view a topic where the form has been used.

Values in other topics

As described above, you can also retrieve possible values for select, checkbox or radio types from other topics. For example, if you have a rows defined like this:
| *Name*                 | *Type* | *Size* |
| AeroplaneManufacturers | select |        |
the Foswiki will look for the topic AeroplaneManufacturers to get the possible values for the select.

The AeroplaneManufacturers topic must contain a table, where each row of the table describes a possible value. The table only requires one column, Name. Other columns may be present, but are ignored.

For example:

| *Name* |
| Routan |
| Focke-Wulf |
| De Havilland |

Notes:

  • The Values column must be empty in the referring form definition.

Extending the range of form data types

You can extend the range of data types accepted by forms by using Plugins. All such extended data types are single-valued (can only have one value) with the following exceptions:
  • any type name starting with checkbox
  • any type name with +multi anywhere in the name
Types with names like this can both take multiple values.

Hints and tips

Build an HTML form to create new form-based topics

  • New topics with a form are created by simple HTML forms asking for a topic name. For example, you can have a SubmitExpenseReport topic where you can create new expense reports, a SubmitVacationRequest topic, and so on. These can specify the required template topic with its associated form. Template topics has more.
A form definition specifies the fields in a form. A form definition is simply a page containing a Foswiki table, where each row of the table specifies one form field.

Searching in form data

The best way to search in form data is using the structured query language in the SEARCH macro. See QuerySearch for more information.

Gotcha!

  • Some browsers may strip linefeeds from text fields when a topic is saved. If you need linefeeds in a field, make sure it is a textarea.

Template topics

Template topics are topics that define the default text for new topics.

Overview

There are four types of template topics:

Topic Name: What it is:
WebCreateNewTopicTemplate Page shown when you click on a newtopic Create New Topic link. It provides a form requesting the necessary information to create a new, nonexistent topic.
TopicDoesNotExistViewTemplate Alert page shown when you try to view a nonexistent topic and usually used as a prompt to help you create this new topic. For this reason, the form of the WebCreateNewTopicTemplate is included and therefore shown, too.
WebTopicEditTemplate Default text used in a new topic.
<MyCustomNamed>Template Whenever you create a topic ending in the word "Template", it is automatically added to the list of available template topics in the "Use Template" drop down field on the WebCreateNewTopic page.

When you create a new topic using the edit script, the system locates a template topic according to the following search order:

  1. A topic name specified by the templatetopic CGI parameter
    • if no web is specified, the current web is searched first and then the System web
  2. WebTopicEditTemplate in the current web
  3. WebTopicEditTemplate in the System web

Macro expansion

When the following macros are used in a template topic, they automatically get expanded when new topic is created based on it:

Macro: Description:
%DATE% Signature format date. See VarDATE
%GMTIME% Date/time. See VarGMTIME
%GMTIME{...}% Formatted date/time. See VarGMTIME
%NOP% A no-operation macro that gets removed. Useful to prevent a SEARCH from hitting an edit template topic; also useful to escape a variable, such as %URLPA%NOP%RAM{...}% escaping URLPARAM
%STARTSECTION{type="templateonly"}%
...
%ENDSECTION{type="templateonly"}%
Text that gets removed when a new topic based on the template topic is created. See notes below.
%SERVERTIME% Date/time. See VarSERVERTIME
%SERVERTIME{...}% Formatted date/time. See VarSERVERTIME
%USERNAME% Login name of user who is instantiating the new topic, e.g. guest
%URLPARAM{"name"}% Value of a named URL parameter
%WIKINAME% WikiName of user who is creating the new topic, e.g. WikiGuest
%WIKIUSERNAME% User name of user who is creating the new topic, e.g. Main.WikiGuest

%STARTSECTION{type="templateonly"}%
...
%ENDSECTION{type="templateonly"}%
markers are used to embed text that you do not want expanded when a new topic based on the template topic is created. For example, you might want to write in the template topic:

%STARTSECTION{type="templateonly"}%
This template topic can only be changed by:
   * Set ALLOWTOPICCHANGE = Main.AdminGroup
%ENDSECTION{type="templateonly"}%
This will restrict who can edit the template topic, but will get removed when a new topic based on that template topic is created.

%NOP% can be used to prevent expansion of macros that would otherwise be expanded during topic creation e.g. escape %SERVERTIME% with %SER%NOP%VERTIME%.

All other macros are unchanged, e.g. are carried over "as is" into the new topic.

Specifying a form

When you create a new topic based on a template topic, you often want the new topic to have a form attached to it. You can attach a form to the template topic, in which case it will automatically be copied into the new topic.

Sometimes this isn't quite what you want, as it copies all the existing data from the template topic into the new topic. To avoid this and use the default values specified in the form definition instead, you can use the formtemplate parameter to the edit script to specify the name of a form to attach.

See CommandAndCGIScripts for information about this, and all the other parameters to edit.

Automatically generated topic names

For some applications it is useful to be able to automatically generate unique topicnames, such as BugID0001, BugID0002, etc. You can add AUTOINC<n> to the topic name in the edit and save scripts, and it will be replaced with an auto-incremented number on topic save. <n> is a number starting from 0, and may include leading zeros. Leading zeros are used to zero-pad numbers so that auto-incremented topic names can sort properly. Deleted topics are not re-used to ensure uniqueness of topic names. That is, the auto-incremented number is always higher than the existing ones, even if there are gaps in the number sequence.

Examples:

  • BugAUTOINC0 - creates topic names Bug0, Bug1, Bug2, ... (does not sort properly)
  • ItemAUTOINC0000 - creates topic names Item0000, Item0001, Item0002, ... (sorts properly up to 9999)
  • DocIDAUTOINC10001 - start with DocID10001, DocID10002, ... (sorts properly up to 99999; auto-links)

Example link to create a new topic:

[[%SCRIPTURLPATH{edit}%/%WEB%/BugIDAUTOINC00001?templatetopic=BugTemplate;topicparent=%TOPIC%;t=%SERVERTIME{"$day$hour$min$sec"}%][Create new item]]

Template topics in action

Here is an example for creating new topics (in the Sandbox web) based on a specific template topic and form:

  • New example topic:  

The above form asks for a topic name. A hidden input tag named templatetopic specifies ExampleTopicTemplate as the template topic to use. Here is the HTML source of the form:

<form name="new" action="%SCRIPTURLPATH{edit}%/Sandbox/" method="post">
   * New example topic:
     <input type="text" name="topic" value="ExampleTopicAUTOINC0001" size="30" />
     <input type="hidden" name="templatetopic" value="ExampleTopicTemplate" />
     <input type="hidden" name="topicparent" value="%TOPIC%" />
     <input type="hidden" name="onlywikiname" value="on" />
     <input type="hidden" name="onlynewtopic" value="on" />
     <input type="submit" class="foswikiSubmit" value="Create" />
</form>

ALERT! Note: You can create a topic in one step, without going through the edit screen. To do that, specify the save script instead of the edit script in the form action. When you specify the save script you must use the "post" method. Example:

<form name="new" action="%SCRIPTURLPATH{save}%/Sandbox/" method="post">
    ...
</form>

See CommandAndCGIScripts#edit for details of the parameters that the edit script understands.

TIP You can use the %WIKIUSERNAME% and %DATE% macros in your template topics to include the signature of the person creating a new topic. The macros are expanded into fixed text when a new topic is created. The standard signature is:
-- %WIKIUSERNAME% - %DATE%

Using absolute vs relative URLs in templates

When you use Macros such as %PUBURL% and %PUBURLPATH% in template topics you should be aware that using %PUBURL% instead of %PUBURLPATH% puts absolute URLs in the produced HTML. This means that when a user saves a page in HTML and emails the file to someone outside a company firewall, the receiver has a severe problem viewing it. It is therefore recommended always to use the %PUBURLPATH% to refer to images, CSS, Javascript files etc so links become relative. This way browsers just give up right away and show a usable html file.

Skin Templates

Definition of the templates used to render output

Overview

Skin Templates are plain text with embedded template macros that describe how to compose blocks of text together, to create something new.

Skin templates are used composing the output from all actions, like view, edit, and preview. This allows you to change the look and feel of all pages by editing just a few template files.

Skin templates are usually stored as text files with the extension .tmpl, though can also come from topic text in some limited circumstances. They are usually HTML with embedded template macros. The macros are expanded when we want to generate output, such as a user interface screen.

How Template Directives Work

  • Directives are of the form %TMPL:<key>% and %TMPL:<key>{"attr"}%.
  • Directives:
    • %TMPL:INCLUDE{"file"}%: Includes a template file. The file is found as described below.
    • %TMPL:DEF{"block"}%: Define a block. All text between this and the next %TMPL:END% directive is removed and saved for later use with %TMPL:P%.
    • %TMPL:END%: Ends a block definition.
    • %TMPL:P{"var"}%: Includes a previously defined block.
    • %{...}%: is a comment.
  • Two-pass processing lets you use a defined block before or after declaring it.
  • For example, you can create a skin that overloads only the foswiki.tmpl master skin template, like foswiki.print.tmpl, that redefines the header and footer.
  • HELP Use of template macros is optional: templates work without them.
  • ALERT! Most template macros work only for templates: they do not get processed in normal topic text. The one exception is %TMPL:P.

TMPL:P also supports simple parameters. For example, given the definition %TMPL:DEF{"x"}% x%P%z%TMPL:END% then %TMPL:P{"x" P="y"}% will expand to xyz.

Note that parameters can simply be ignored; for example, %TMPL:P{"x"}% will expand to x%P%z.

Any alphanumeric characters can be used in parameter names. You are highly recommended to use parameter names that cannot be confused with macros.

Note that three parameter names, context, then and else are reserved. They are used to support a limited form of "if" condition that you can use to select which of two TMPL:DEFs to use, based on a context identifier:

%TMPL:DEF{"link_inactive"}%<input type="button" disabled value="Link>%TMPL:END%
%TMPL:DEF{"link_active"}%<input type="button" onclick="link()" value="Link" />%TMPL:END%
%TMPL:P{context="inactive" then="inactive_link" else="active_link"}% for %CONTEXT%
When the "inactive" context is set, then this will expand the "link_inactive" TMPL:DEF; otherwise it will expand the "link_active" TMPL:DEF. See IfStatements for details of supported context identifiers.

Finding Skin Templates

The skin templates shipped with a release are stored in the templates directory. As an example, templates/view.tmpl is the default skin template file for the bin/view script.

You can save templates in other directories as long as they are listed in the {TemplatePath} configuration setting. The {TemplatePath} is defined in the Miscellaneous section of the configure page.

You can also save skin templates in user topics (IF there is no possible template match in the templates directory). The {TemplatePath} configuration setting defines which topics will be accepted as templates.

Skin templates that are included with an explicit '.tmpl' extension are looked for only in the templates/ directory. For instance %TMPL:INCLUDE{"example.tmpl"}% will only return templates/example.tmpl, regardless of {TemplatePath} and SKIN settings.

The out-of-the-box setting of {TemplatePath} supports the following search order to determine which template file or topic to use for a particular script or %TMPL:INCLUDE{"script"}% statement. The skin path is set as described in Skins.

  1. templates/%DARKGRAY%web/%DARKGRAY%script.%DARKGRAY%skin.tmpl for each %DARKGRAY%skin on the skin path
    • ALERT! this usage is supported for compatibility only and is deprecated. Store web-specific templates in topics instead.
  2. templates/script.skin.tmpl for each skin on the skin path
    • for example templates/view.dragon.tmpl
  3. templates/%DARKGRAY%web/%DARKGRAY%script.tmpl
    • ALERT! this usage is supported for compatibility only and is deprecated. Store web-specific templates in topics instead.
  4. templates/script.tmpl
    • for example templates/view.tmpl
  5. The topic aweb.atopic if the template name can be parsed into aweb.atopic
  6. The topic web.SkinSkinScriptTemplate for each skin on the skin path
    • for example DragonSkinViewTemplate in the current Web
  7. The topic web.ScriptTemplate
  8. The topic %SYSTEMWEB%.SkinSkinScriptTemplate for each skin on the skin path
    • for example System.DragonSkinViewTemplate
  9. The topic %SYSTEMWEB%.ScriptTemplate
Legend:
  • script refers to the script name, e.g view, edit
  • Script refers to the same, but with the first character capitalized, e.g View
  • skin refers to a skin name, e.g dragon, pattern. All skins are checked at each stage, in the order they appear in the skin path.
  • Skin refers to the same, but with the first character capitalized, e.g Dragon
  • web refers to the current web

For example, the example template file will be searched for in the following places, when the current web is Thisweb and the skin path is print,pattern:

  1. templates/Thisweb/example.print.tmpl deprecated; don't rely on it
  2. templates/Thisweb/example.pattern.tmpl deprecated; don't rely on it
  3. templates/example.print.tmpl
  4. templates/example.pattern.tmpl
  5. templates/Thisweb/example.tmpl deprecated; don't rely on it
  6. templates/example.tmpl
  7. Thisweb.PrintSkinExampleTemplate
  8. Thisweb.PatternSkinExampleTemplate
  9. Thisweb.ExampleTemplate
  10. System.PrintSkinExampleTemplate
  11. System.PatternSkinExampleTemplate
  12. System.ExampleTemplate

Template names are usually derived from the name of the currently executing script; however it is also possible to override these settings in the view and edit scripts, for example when a topic-specific template is required. Two preference settings can be used to override the skin templates used:

  • VIEW_TEMPLATE sets the template to be used for viewing a topic.
  • EDIT_TEMPLATE sets the template for editing a topic.
If these preferences are set locally (using Local instead of Set) for a topic, in WebPreferences, in Main.SitePreferences, or System.DefaultPreferences (using Set), the indicated templates will be chosen for view and edit respectively. The template search order is as specified above.

TMPL:INCLUDE recursion for piecewise customisation, or mixing in new features

If there is recursion in the TMPL:INCLUDE chain (eg view.tmpl contains %TMPL:INCLUDE{"foswiki"}%, the templating system will include the next SKIN in the skin path. For example, to create a customisation of pattern skin, where you only want to over-ride the breadcrumbs for the view script, you can create only a view.yourlocal.tmpl:

%TMPL:INCLUDE{"view"}%
%TMPL:DEF{"breadcrumb"}% We don't want any crumbs %TMPL:END%
and then set SKIN=yourlocal,pattern

The default {TemplatePath} will not give you the desired result if you put these statements in the topic Thisweb.YourlocalSkinViewTemplate. The default {TemplatePath} will resolve the request to the template/view.pattern.tmpl, before it gets to the Thisweb.YourlocalSkinViewTemplate resolution. You can make it work by prefixing the {TemplatePath} with: $web.YourlocalSkin$nameTemplate.

Default master template

foswiki.tmpl is the default master template. It defines the following sections.

Template directive: Defines:
%TMPL:DEF{"sep"}% "|" separator
%TMPL:DEF{"htmldoctype"}% Start of all HTML pages
%TMPL:DEF{"standardheader"}% Standard header (ex: view, index, search)
%TMPL:DEF{"simpleheader"}% Simple header with reduced links (ex: edit, attach, oops)
%TMPL:DEF{"standardfooter"}% Footer, excluding revision and copyright parts

Foswiki Skins

Skins overlay regular templates to give different looks and feels to Foswiki screens.

Overview

Foswiki uses skin templates as the basis of all the screens it uses to interact with users. Each screen has an associated template file that contains the basic layout of the screen. This is then filled in by the code to generate what you see in the browser.

Foswiki ships with a default set of template files that give a very basic, CSS-themable, look-and-feel. Foswiki also includes support for skins that can be selected to give different, more sophisticated, look and feel. A default Foswiki installation will usually start up with the PatternSkin already selected. Skins may also be defined by third parties and loaded into a Foswiki installation to give more options. To see how Foswiki looks when no skin is selected, view this topic with a non-existant skin.

Topic text is not affected by the choice of skin, though a skin can be defined to use a CSS (Cascading Style Sheet), which can sometimes give a radically different appearance to the text.

Relevant links

See other types of extensions: ContributedAddOns, Contribs, Plugins

Changing the default skin

STALklubben by default ships with the skin PatternSkin activated. You can set the skin for the whole site, a single web or topic, or for each user individually, by setting the SKIN setting to the name of a skin. If the skin you select doesn't exist, then STALklubben will pick up the default templates.

Defining Skins

You may want to define your own skin, for example to comply with corporate web guidelines, or because you have a aesthetic vision that you want to share. There are a couple of places you an start doing this.

The skin templates used for skins are located in the templates directory and are named according to the skin: <scriptname>.<skin>.tmpl. Skin files may also be defined in Foswiki topics - see SkinTemplates for details.

To start creating a new skin, copy the default skin templates (like view.tmpl), or copy an existing skin to use as a base for your own skin. You should only need to copy the files you intend to customise, as Foswiki can be configured to fall back to another skin if a template is not defined in your skin. A custom skin can be as small as one file! Name your files as described above (for example view.myskin.tmpl).

If you use PatternSkin as your starting point, and you want to modify the layout, colors or even the templates to suit your own needs, have a look first at the topics PatternSkinCustomization and PatternSkinCssCookbook. These topics also provide practical instructions how to create custom skin template files.

ALERT! Note: Don't call your skin text or rss as these two skin names have reserved meanings, see below at hard-coded meanings.

The following template files are used for Foswiki screens, and are referenced in the Foswiki core code. If a skin doesn't define its own version of a template file, then Foswiki will fall back to the next skin in the skin path, or finally, to the default version of the template file.

(Certain template files are expected to provide certain TMPL:DEFs - these are listed in sub-bullets)

foswiki.tmpl is a master template conventionally used by other templates, but not used directly by code.

ALERT! Note: Make sure templates do not end with a newline. Any newline will expand to an empty <p /> in the generated html. It will produce invalid html, and may break the page layout.

Partial customisation, or adding in new features to an existing skin

You can use recusion in the TMPL:INCLUDE chain (eg view.tmpl contains %TMPL:INCLUDE{"foswiki"}%, the templating system will include the next SKIN in the skin path. For example, to create a customisation of pattern skin, where you only want to remove the edit & WYSIWYG buttons from view page, you create only a view.yourlocal.tmpl:

%TMPL:INCLUDE{"view"}%
%TMPL:DEF{"edit_topic_link"}%%TMPL:END%
%TMPL:DEF{"edit_wysiwyg_link"}%%TMPL:END%
and then set SKIN=yourlocal,pattern

Settings in Skins

You can use template directives, ordinary macros, and other predefined settings in your skins. Some commonly used macros in skins:

Macro: Expanded to:
%WEBLOGONAME% Filename of web logo
%WEBLOGOIMG% Image URL of web logo
%WEBLOGOURL% Link of web logo
%WEBLOGOALT% Alt text of web logo
%WIKILOGOURL% Link of page logo
%WIKILOGOIMG% Image URL of page logo
%WIKILOGOALT% Alt text of page logo
%WEBBGCOLOR% Web-specific background color, defined in the WebPreferences
%WIKITOOLNAME% The name of your Foswiki site
%SCRIPTURL% The script URL of Foswiki
%SCRIPTURLPATH% The script URL path
%SCRIPTSUFFIX% The script suffix, ex: .pl, .cgi
%WEB% The name of the current web.
%TOPIC% The name of the current topic.
%WEBTOPICLIST% Common links of current web, defined in the WebPreferences. It includes a Go box
%TEXT% The topic text, e.g. the content that can be edited
%META{"form"}% DataForm, if any
%META{"attachments"}% FileAttachment table
%META{"parent"}% The topic parent
%EDITTOPIC% Edit link
%REVTITLE% The revision title, if any, ex: (r1.6)
%REVINFO% Revision info, ex: r1.6 - 24 Dec 2002 - 08:12 GMT - Main.WikiGuest
%WEBCOPYRIGHT% Copyright notice, defined in the WebPreferences
%BROADCASTMESSAGE% Broadcast message at the beginning of your view template, can be used to alert users of scheduled downtimes; can be set in Main.SitePreferences

Using Cascading Style Sheets

CSS files are gererally attachments to the skin topic that are included in the the skin templates - in the case of PatternSkin in the template css.pattern.tmpl.

  • General documentation of CSS classes: CascadingStyleSheets
  • To see how CSS is used in the default Foswiki skin, see: PatternSkin
  • If you write a complete new skin, this is the syntax to use in a template file:
<style type='text/css' media='all'>@import url('%PUBURLPATH%/%SYSTEMWEB%/MySkin/mystyle.css');</style>

Skin parts

The "Go" Box and Navigation Box

The default skins include a "Go" box, also called "Jump" box, to jump to a topic.

The box also understands URLs, e.g. you can type http://www.google.com/ to jump to an external web site. The feature is handy if you build a skin that has a select box of frequently used links, like Intranet home, employee database, sales database and such. A little JavaScript gets into action on the onchange method of the select tag to fill the selected URL into the "Go" box field, then submits the form.

Here is an example form that has a select box and the "Go" box for illustration purposes. You need to have JavaScript enabled for this to work:

Bare bones header, for demo only
Navigate:
Jump:

Note: Redirect to a URL only works if it is enabled in configure (Miscellaneous, {AllowRedirectUrl}).

FLASHNOTE Notifications

PatternSkin has a notification message display using the variable FLASHNOTE. For example:

  • Set FLASHNOTE = Skins documentation

See the alert at the top of this topic.

While this feature is not yet used by the system, it might be a good idea to already prepare your skin.

Attachment Tables

Controlling the look and feel of attachment tables is a little bit more complex than for the rest of a skin. By default, the attachment table is a standard Foswiki table, and the look is controlled in the same way as other tables. In a very few cases you may want to change the content of the table as well.

The format of standard attachment tables is defined through the use of special template directives which by default, are defined in the attachtables.tmpl template using the %TMPL:DEF directive syntax described in SkinTemplates. These macros are:

Macro Description
ATTACH:files:header Standard title bar
ATTACH:files:row Standard row
ATTACH:files:footer Footer for all screens
ATTACH:files:header:A Title bar for upload screens, with attributes column
ATTACH:files:row:A Row for upload screen
ATTACH:files:footer:A Footer for all screens

The format of tables of file versions in the Upload screen can also be changed, using the macros:

Macro Description
ATTACH:versions:header Header for versions table on upload screen
ATTACH:versions:row Row format for versions table on upload screen
ATTACH:versions:footer Footer for versions table on upload screen

The ATTACH:row macros are expanded for each file in the attachment table, using the following special tags:

Tag Description
%A_URL% viewfile URL that will recover the file
%A_REV% Revision of this file
%A_ICON% A file icon suitable for representing the attachment content
%A_FILE% The name of the file. To get the 'pub' url of the file, use %PUBURL%/%WEB%/%TOPIC%/%A_FILE%
%A_SIZE% The size of the file
%A_DATE% The date the file was uploaded
%A_USER% The user who uploaded it
%A_COMMENT% The comment they put in when uploading it
%A_ATTRS% The attributes of the file as seen on the upload screen e.g "h" for a hidden file

Packaging and Publishing Skins

See Foswiki:Extensions/SkinPackagingHowTo and Foswiki:Extensions/SkinDeveloperFAQ

For your own skin you are encouraged to show a small 80x31 pixel This site is powered by Foswiki logo at the bottom of your skin:

<a href="http://foswiki.org/"><img src="%PUBURL%/%SYSTEMWEB%/ProjectLogos/foswiki-poweredby.gif" alt="This site is powered by Foswiki" width="80" height="15" title="This site is powered by Forwiki" border="0" /></a>

The standard STALklubben skins show the logo in the %WEBCOPYRIGHT%.

Browsing Installed Skins

You can try out all installed skins in the SkinBrowser.

Activating Skins

Foswiki uses a skin search path, which lets you combine skins additively. The skin path is defined using a combination of macros and URL parameters.

Foswiki works by asking for a template for a particular function - for example, 'view'. The detail of how templates are searched for is described in SkinTemplates, but in summary, the templates directory is searched for a file called view.skin.tmpl, where skin is the name of the skin e.g. pattern. If no template is found, then the fallback is to use view.tmpl. Each skin on the path is searched for in turn. For example, if you have set the skin path to local,pattern then view.local.tmpl will be searched for first, then view.pattern.tmpl and finally view.tmpl.

The basic skin is defined by a SKIN setting:

  • Set SKIN = catskin, bearskin

You can also add a parameter to the URL, such as ?skin=catskin,bearskin:

Setting SKIN (or the ?skin parameter in the URL) replaces the existing skin path setting, for the current page only. You can also extend the existing skin path as well, using covers.

  • Set COVER = ruskin

This pushes a different skin to the front of the skin search path (so for our example above, that final skin path will be ruskin, catskin, bearskin). There is also an equivalent cover URL parameter. The difference between setting SKIN vs. COVER is that if the chosen template is not found (e.g., for included templates), SKIN will fall back onto the next skin in line, or the default skin, if only one skin was present, while COVER will always fall back onto the current skin.

An example would be invoking the printable mode, which is achieved by applying ?cover=print. The view.print.tmpl simply invokes the viewprint template for the current skin which then can appropriately include all other used templates for the current skin. Where the printable mode be applied by using SKIN, all skins would have the same printable appearance.

The full skin path is built up as follows: SKIN setting (or ?skin if it is set), then COVER setting is added, then ?cover.

Hard-Coded Skins

The text skin is reserved for Foswiki internal use.

Skin names starting with rss also have a special meaning; if one or more of the skins in the skin path starts with 'rss' then 8-bit characters will be encoded as XML entities in the output, and the content-type header will be forced to text/xml.

Meta data

Additional topic data, program-generated or from DataForms, is stored embedded in the topic text using META: tags

Overview

By default, topics are stored in files on disk, in a really simple and obvious directory structure. The big advantage of this approach is that it makes it really easy to manipulate topics from outside, and is also very safe; there are no complex binary indexes to maintain, and moving a topic from one installation to another is as simple as copying a couple of text files.

To keep eveything together in one place, meta-data (program-generated or from DataForms) is embedded directly in topics. It does this using META: tags.

META: data includes program-generated info like FileAttachment, topic movement data and user-defined information from DataForms.

Meta data syntax

  • Format is the same as in macros, except all fields have a key.
    • %META:<type>{key1="value1" key2="value2" ...}%

  • Order of fields within the meta-data is not defined, except that if there is a field with key name, this appears first for easier searching (note the order of the data themselves is defined).

  • Each meta-datum is on one line.

  • Values in meta-data are URL encoded so that characters such as \n can be stored.

Example of Format
%META:TOPICINFO{version="1.6" date="976762663" author="LastEditorWikiName" format="1.0"}%
   text of the topic
%META:TOPICMOVED{from="Codev.OldName" to="Codev.NewName"
   by="TopicMoverWikiName" date="976762680"}%
%META:TOPICPARENT{name="NavigationByTopicContext"}%
%META:FILEATTACHMENT{name="Sample.txt" version="1.3" ... }%
%META:FILEATTACHMENT{name="Smile.gif" version="1.1" ... }%
%META:FORM{name="WebFormTemplate"}%
%META:FIELD{name="OperatingSystem" value="OsWin"}%
%META:FIELD{name="TopicClassification" value="PublicFAQ"}%

Meta data specifications

The current version of Meta Data is 1.0, with support for the following syntax.

META:TOPICINFO

Key Comment
version Same as SVN version
date integer, unix time, seconds since start 1970
author last to change topic, is the REMOTE_USER
format Format of this topic, will be used for automatic format conversion

META:TOPICMOVED

This is optional, exists if topic has ever been moved. If a topic is moved more than once, only the most recent META:TOPICMOVED meta datum exists in the topic, older ones are to be found in the rcs history.

%META:TOPICMOVED{from="Codev.OldName" to="Codev.NewName" by="talintj" date="976762680"}%

Key Comment
from Full name, i.e., web.topic
to Full name, i.e., web.topic
by Who did it, is the REMOTE_USER, not WikiName
date integer, unix time, seconds since start 1970

Notes:

  • at present version number is not supported directly, it can be inferred from the SVN history.
  • there is only one META:TOPICMOVED in a topic, older move information can be found in the SVN history.

META:TOPICPARENT

Key Comment
name The topic from which this was created, typically when clicking on a ? questionmark link, or by filling out a form. Normally just TopicName, but it can be a full Web.TopicName format if the parent is in a different Web.

META:FILEATTACHMENT

Key Comment
name Name of file, no path. Must be unique within topic
version Same as SVN revision
path Full path file was loaded from
size In bytes
date integer, unix time, seconds since start 1970
user the REMOTE_USER, not WikiName
comment As supplied when file uploaded
attr h if hidden, optional

Extra fields that are added if an attachment is moved:

Key Comment
movedfrom full topic name - web.topic
movedby the REMOTE_USER, not WikiName
movedto full topic name - web.topic
moveddate integer, unix time, seconds since start 1970

META:FORM

Key Comment
name A topic name - the topic represents one of the DataForms. Can optionally include the web name (i.e., web.topic), but doesn't normally

META:FIELD

Should only be present if there is a META:FORM entry. Note that this data is used when viewing a topic; the form definition is not read.

Key Name
name Ties to entry in DataForms template, is title with all bar alphanumerics and . removed
title Full text from DataForms template
value Value user has supplied via form

Recommended sequence

There is no absolute need for Meta data to be listed in a specific order within a topic, but it makes sense to do so for a couple of good reasons:

  • form fields remain in the order they are defined
  • the diff function output appears in a logical order

The recommended sequence is:

  • META:TOPICINFO
  • META:TOPICPARENT (optional)
  • text of topic
  • META:TOPICMOVED (optional)
  • META:FILEATTACHMENT (0 or more entries)
  • META:FORM (optional)
  • META:FIELD (0 or more entries; FORM required)

Viewing meta data in page source

When viewing a topic the [View raw text] link can be clicked to show the text of a topic (i.e., as seen when editing). This is done by adding raw=on to URL. raw=debug shows the meta data as well as the topic data, ex: debug view for this topic

Rendering meta data

Meta data is rendered with the %META% macro. This is mostly used in the view, preview and edit scripts.

You can render form fields in topic text by using the FORMFIELD macro. Example:
%FORMFIELD{"TopicClassification"}%
For details, see VarFORMFIELD.

Current support covers:

Macro usage: Comment:
%META{"form"}% Show form data, see DataForms.
%META{"formfield"}% Show form field value. Parameter: name="field_name". Example:
%META{ "formfield" name="TopicClassification" }%
%META{"attachments"}% Show attachments, except for hidden ones. Options:
all="on": Show all attachments, including hidden ones.
%META{"moved"}% Details of any topic moves.
%META{"parent"}% Show topic parent. Options:
dontrecurse="on": By default recurses up tree, at some cost.
nowebhome="on": Suppress WebHome.
prefix="...": Prefix for parents, only if there are parents, default "".
suffix="...": Suffix, only appears if there are parents, default "".
separator="...": Separator between parents, default is " > ".

HELP SEARCH can also be used to render meta data, see examples in FormattedSearch and SearchPatternCookbook.

Add-Ons

Add functionality with extensions not based on the Foswiki scripts.

Overview

An add-on runs separately from the Foswiki scripts, e.g. for data import, export to static HTML, etc. Add-Ons normally do not call any Foswiki code directly, though may invoke Foswiki scripts. There are different types of add-ons, they may be stand alone scripts, browser plugins, office tool extensions, or even a set of topics that form a wiki application.

Foswiki Contribs

Extensions that sit close to the core, or provide services for other extensions

Overview

Foswiki contribs extend the functionality of Foswiki, in a lower-level way than plugins and add-ons. They may also provide alternative implementations for sections of the Foswiki core e.g. user management, or when an extension just can't be implemented as a plugin because it requires very close access to Foswiki internals.

An example is the MailerContrib, which implements mail notification of topics changes.

Foswiki Plugins

Add functionality to Foswiki with plugins

Overview

You can add plugins to extend Foswiki functionality without altering the core code. A plug-in approach lets you:

  • add virtually unlimited features while keeping the main Foswiki code compact and efficient;
  • heavily customize an installation and still do clean updates to new versions of Foswiki;
  • rapidly develop new Foswiki functions in Perl using the plugin API.

Everything to do with Foswiki plugins - demos, new releases, downloads, development, general discussion - is available at Foswiki.org, in the Foswiki:Extensions web.

Foswiki plugins are developed and contributed by interested members of the community. Plugins are provided on an 'as is' basis; they are not a part of Foswiki, but are independently developed and maintained.

Most TWiki® plugins can also be used with Foswiki if the TWikiCompatibilityPlugin is installed (it is by default).

Installing Plugins

Each Foswiki plugin comes with its own documentation: step-by-step installation instructions, a detailed description of any special requirements, version details, and a working example for testing. Many plugins have an install script that automates these steps for you.

Special Requirements: Some plugins need certain Perl modules to be preinstalled on the host system. Plugins may also use other resources, like graphics, other modules, applications, and templates. You should be able to find detailed instructions in the plugin's documentation.

Each plugin has a standard release topic, located in the Foswiki:Extensions web at Foswiki.org. There's usually a number of other related topics, such as a developers page, and an appraisal page.

On-Site Pretesting

The recommended approach to testing new plugins before making them public is to create a second local Foswiki installation, and test the plugin there. You can allow selected users access to the test area. Once you are satisfied that it won't compromise your main installation, you can install it there as well.

The plugins page shows which plugins are: 1) installed, 2) loading properly, and 3) what plugin handlers they invoke. Any failures are shown in the Errors section. The %FAILEDPLUGINS% macro can be used to debug failures. You may also want to check your webserver error log and the various Foswiki log files.

Some Notes on Plugin Performance

The performance of the system depends to some extent on the number of plugins installed and on the plugin implementation. Some plugins impose no measurable performance decrease, some do. For example, a Plugin might use many Perl libraries that need to be initialized with each page view (unless you run mod_perl). You can only really tell the performance impact by installing the plugin and by measuring the performance with and without the new plugin, on real data.

TIP If you need to install an "expensive" plugin, but you only need its functionality only in a subset of your data, you can disable it elsewhere by defining the %DISABLEDPLUGINS% setting.

Define DISABLEDPLUGINS to be a comma-separated list of names of plugins to disable. Define it in Main.SitePreferences to disable those plugins everywhere, in the WebPreferences topic to disable them in an individual web, or in a topic to disable them in that topic. For example,

   * Set DISABLEDPLUGINS = SpreadSheetPlugin, EditTablePlugin

Managing Installed Plugins

Some plugins require additional settings or offer extra options that you have to select. Also, you may want to make a plugin available only in certain webs, or temporarily disable it. And may want to list all available plugins in certain topics. You can handle all of these management tasks with simple procedures:

Listing Active Plugins

Plugin status macros let you list all active plugins wherever needed.

This site is running Foswiki version Foswiki-1.0.9, Sun, 17 Jan 2010, build 6075, plugin API version 2.0

  • %ACTIVATEDPLUGINS% - shows the activated plugins
  • %PLUGINVERSION% - shows the plugins API version
  • %FAILEDPLUGINS% - shows what plugins failed, and why

Enabling Plugins

Plugins can be enabled and disabled with the configure script. An installed plugin needs to be enabled before it can be used.

Plugin Evaluation Order

By default, plugins are executed in alphabetical order on plugin name. It is possible to change the order, for example to evaluate database macros before the spreadsheet CALCs. This can be done with {PluginsOrder} in the plugins section of configure.

Plugin-Specific Settings

Some plugins are configured with plugin preference settings, newer plugins with configure settings.

configure settings are accessible though the configure interface.

Plugin preference settings are defined in the plugin topic and can be overloaded. The SHORTDESCRIPTION setting is always present, it is needed for the automation in the extensions repository. Example preference settings defined in the TablePlugin topic:

  • Set SHORTDESCRIPTION = Control attributes of tables and sorting of table columns

Preference settings of active plugins can be retrieved anywhere in Foswiki with %<pluginname>_<var>%, such as %TABLEPLUGIN_SHORTDESCRIPTION%. They can also be redefined with the %<pluginname>_<var>% setting at a lower level in the Main.SitePreferences or at the web level. For an easier upgrade it is recommended to customize plugin preference settings in Main.SitePreferences only.

Installing Plugins

Each Foswiki plugin comes with its own documentation: step-by-step installation instructions, a detailed description of any special requirements, version details, and a working example for testing. Many plugins have an install script that automates these steps for you.

Special Requirements: Some plugins need certain Perl modules to be preinstalled on the host system. Plugins may also use other resources, like graphics, other modules, applications, and templates. You should be able to find detailed instructions in the plugin's documentation.

Each plugin has a standard release topic, located in the Foswiki:Extensions web at Foswiki.org. There's usually a number of other related topics, such as a developers page, and an appraisal page.

The Foswiki Perl Application Programming Interface

Developing plugins provides a simple introduction to hooking into Foswiki code from your own Perl modules. Foswiki:Development.GettingStarted is the starting point for more comprehensive documentation.

Back to top


Developing Plugins

The usual way Foswiki is extended is by writing a Plugin. Plugins extend Foswiki by providing functions that 'listen' to events in the Foswiki core, and handling these events. These functions are called "Plugin Handlers" and they are described in depth in EmptyPlugin ( lib/Foswiki/Plugins/EmptyPlugin.pm ).

APIs available to Extensions

To be robust, extensions must avoid using any unpublished functionality from the Foswiki core. The following perl packages give access to features for extension authors. These APIs are not just for Plugins, they can be used in any type of extension. Click on the name of the package to see the full documentation. In addition the following global variables may be referred to:
  • $Foswiki::Plugins::VERSION - plugin handler API version number
  • $Foswiki::Plugins::SESSION - reference to Foswiki singleton object
  • $Foswiki::cfg - reference to configuration hash
  • $Foswiki::regex - see Standard Regular Expressions, below
IDEA! Foswiki:Development.GettingStarted is the starting point for more comprehensive documentation on developing for Foswiki.

Note the APIs are available to all extensions, but rely on a Foswiki singleton object having been created before the APIs can be used. This will only be a problem if you are writing an extension that doesn't use the standard initialisation sequence.

Standard Regular Expressions

A number of standard regular expressions are available for use in extensions, in the $Foswiki::regex hash. these regular expressions are precompiled in an I18N-compatible manner. The following are guaranteed to be present. Others may exist, but their use is unsupported and they may be removed in future Foswiki versions.

In the table below, the expression marked type 'String' are intended for use within character classes (i.e. for use within square brackets inside a regular expression), for example:

   my $isCapitalizedWord =
     ( $s =~ /[$Foswiki::regex{upperAlpha}][$Foswiki::regex{mixedAlpha}]+/ );
Those expressions marked type 'RE' are precompiled regular expressions that can be used outside square brackets. For example:
   my $isWebName = ( $s =~ m/$Foswiki::regex{webNameRegex}/ );

Name Matches Type
upperAlpha Upper case characters String
upperAlphaNum Upper case characters and digits String
lowerAlpha Lower case characters String
lowerAlphaNum Lower case characters and digits String
numeric Digits String
mixedAlpha Alphabetic characters String
mixedAlphaNum Alphanumeric characters String
wikiWordRegex WikiWords RE
webNameRegex User web names RE
topicNameRegex Topic names RE
anchorRegex #AnchorNames RE
abbrevRegex Abbreviations/Acronyms e.g. GOV, IRS RE
emailAddrRegex email@address_ta_bort_.com RE
tagNameRegex Standard macro names e.g. %THIS_BIT% (THIS_BIT only) RE

Creating New Plugins

With a reasonable knowledge of the Perl scripting language, you can create new plugins or modify and extend existing ones.

Anatomy of a Plugin

A (very) basic Foswiki plugin consists of two files:

  • a Perl module, e.g. lib/Foswiki/Plugins/MyFirstPlugin.pm
  • a documentation topic, e.g. MyFirstPlugin.txt

The Perl module can invoke other, non-Foswiki, elements, like other Perl modules (including other plugins), graphics, external applications, or just about anything else that Perl can call.

The plugin API handles the details of connecting your Perl module with the Foswiki core.

The Foswiki:Extensions.BuildContrib module provides a lot of support for plugins development, including a plugin creator, automatic publishing support, and automatic installation script writer. If you plan on writing more than one plugin, you probably need it.

Creating the Perl Module

Copy file lib/Foswiki/Plugins/EmptyPlugin.pm to <name>Plugin.pm. The EmptyPlugin does nothing, but it contains all the information you need to create you own custom plugin.

Writing the Documentation Topic

The plugin documentation topic contains usage instructions and version details. (The doc topic is also included in the distribution package.) To create a documentation topic:

  1. Copy the plugin topic template from EmptyPlugin?
  2. Customize your plugin topic.
    • Important: In case you plan to publish your plugin on Foswiki.org, use Interwiki names for author names and links to Foswiki.org topics, such as Foswiki:Main/WikiGuest. This is important because links should work properly in a plugin topic installed on any Foswiki, not just on Foswiki.org.
  3. Save your topic, for use in packaging and publishing your plugin.

OUTLINE: Doc Topic Contents
Check the plugins web on Foswiki.org for the latest plugin doc topic template. Here's a quick overview of what's covered:

Syntax Rules: <Describe any special text formatting that will be rendered.>"

Example: <Include an example of the plugin in action. Possibly include a static HTML version of the example to compare if the installation was a success!>"

Plugin Settings: <Description and settings for custom plugin settings, and those required by Foswiki.>"

  • Plugins Preferences <If user settings are needed, link to preference settings and explain the role of the plugin name prefix

Plugin Installation Instructions: <Step-by-step set-up guide, user help, whatever it takes to install and run, goes here.>"

Plugin Info: <Version, credits, history, requirements - entered in a form, displayed as a table. Both are automatically generated when you create or edit a page in the Foswiki:Extensions web.>

Packaging for Distribution

The Foswiki:Extensions.BuildContrib is a powerful build environment that is used by the Foswiki project to build Foswiki itself, as well as many of the plugins. You don't have to use it, but it is highly recommended!

If you don't want to (or can't) use the BuildContrib, then a minimum plugin release consists of a Perl module with a WikiName that ends in Plugin, ex: MyFirstPlugin.pm, and a documentation page with the same name(MyFirstPlugin.txt).

  1. Distribute the plugin files in a directory structure that mirrors Foswiki. If your plugin uses additional files, include them all:
    • lib/Foswiki/Plugins/MyFirstPlugin.pm
    • data/Foswiki/MyFirstPlugin.txt
    • pub/Foswiki/MyFirstPlugin/uparrow.gif [a required graphic]
  2. Create a zip archive with the plugin name (MyFirstPlugin.zip) and add the entire directory structure from Step 1. The archive should look like this:
    • lib/Foswiki/Plugins/MyFirstPlugin.pm
    • data/Foswiki/MyFirstPlugin.txt
    • pub/Foswiki/MyFirstPlugin/uparrow.gif

Publishing for Public Use

You can release your tested, packaged plugin to the Foswiki community through the Foswiki:Extensions web. All plugins submitted to Foswiki.org are available for public download and further development.

Publish your plugin by following these steps:

  1. Post the plugin documentation topic to the Foswiki:Extensions web
  2. Attach the distribution zip file(s) to the topic, eg: MyFirstPlugin.zip
  3. Add a user support hub by visiting Foswiki:Support.CreateNewSupportHub
  4. Optionally, check in the sources to the Foswiki subversion repository (see Foswiki:Development.HowToStartExtensionDevelopmentInSubversion)

NEW Once you have done the above steps once, you can use the BuildContrib to upload updates to your plugin.

Thank you very much for sharing your plugin with the Foswiki community smile

Hints on Writing Fast Plugins

  • Delay initialization as late as possible. For example, if your plugin is a simple syntax processor, you might delay loading extra Perl modules until you actually see the syntax in the text.
    • For example, use an eval block like this:
      eval { require IPC::Run }
      return "<font color=\"red\">SamplePlugin: Can't load required modules ($@)</font>" if $@;
  • Keep the main plugin package as small as possible; create other packages that are loaded if and only if they are used. For example, create sub-packages of BathPlugin in lib/Foswiki/Plugins/BathPlugin/.
  • Avoid using preferences in the plugin topic; set $NO_PREFS_IN_TOPIC if you possibly can, as that will stop Foswiki from reading the plugin topic for every page. Use Config.spec instead.
  • Use registered tag handlers

Security

  • Badly written plugins can open security holes in Foswiki. This is especially true if care isn't taken to prevent execution of arbitrary commands on the server.
  • Don't allow sensitive configuration data to be edited by users. Use the %Foswiki::cfg hash for configuration options. Don't ask installers to edit topics in the System web.
  • Make sure that all user input is checked and validated. Be especially careful to filter characters that might be used in perl string interpolation.
  • Avoid eval, and if you must use it make sure you sanitise parameters
  • Always use the Foswiki::sandbox to execute commands. Never use backtick or qx//.
  • Use Foswiki::Func::checkAccessPermission to check the access rights of the current user.
  • Always audit the plugins you install, and make sure you are happy with the level of security provided. While every effort is made to monitor plugin authors activities, at the end of the day they are uncontrolled user contributions.

Recommended Storage of Plugin Specific Data

Plugins sometimes need to store data. This can be plugin internal data such as cache data, or data generated for browser consumption such as images. Plugins should store data using Foswiki::Func functions that support saving and loading of topics and attachments.

Plugin Internal Data

You can create a plugin "work area" using the Foswiki::Func::getWorkArea() function, which gives you a persistent directory where you can store data files. By default they will not be web accessible. The directory is guaranteed to exist, and to be writable by the webserver user. For convenience, Foswiki::Func::storeFile() and Foswiki::Func::readFile() are provided to persistently store and retrieve simple data in this area.

Web Accessible Data

The internal data area is not normally made web-accessible for security reasons. If yoou want to store web accessible data, for example generated images, then you should use Foswiki's attachment mechanisms.

Topic-specific data such as generated images can be stored in the topic's attachment area, which is web accessible. Use the Foswiki::Func::saveAttachment() function to store the data.

Recommendation for file name:

  • Prefix the filename with an underscore (the leading underscore avoids a name clash with files attached to the same topic)
  • Identify where the attachment originated from, typically by including the plugin name in the file name
  • Use only alphanumeric characters, underscores, dashes and periods to avoid platform dependency issues and URL issues
  • Example: _GaugePlugin_img123.gif
Such auto-generated attachments han be hidden from users by setting the 'h' attribute in the attachment attributes.

Web specific data should be stored in the attachment area of a topic in the web that you specify for the purpose, e.g. Web.BathPlugPictures. Use the Foswiki::Func::saveAttachment() function to store the data in this topic.

Integrating with configure

Some extensions have setup requirements that are best integrated into configure rather than trying to use preference settings. These extensions use Config.spec files to publish their configuration requirements.

Config.spec files are read during configuration. Once a Config.spec has defined a configuration item, it is available for edit through the standard configure interface. Config.spec files are stored in the 'plugin directory' e.g. lib/Foswiki/Plugins/BathPlugin/Config.spec.

Structure of a Config.spec file

The Config.spec file for a plugin starts with the plugin announcing what it is:
# ---+ BathPlugin
# This plugin senses the level of water in your bath, and ensures the plug
# is not removed while the water is still warm.
This is followed by one or more configuration items. Each configuration item has a type, a description and a default. For example:
# **SELECT Plastic,Rubber,Metal**
# Select the plug type
$Foswiki::cfg{BathPlugin}{PlugType} = 'Plastic';

# **NUMBER**
# Enter the chain length in cm
$Foswiki::cfg{BathPlugin}{ChainLength} = '30';

# **BOOLEAN EXPERT**
# Turn this option off to disable the water temperature alarm
$Foswiki::cfg{BathPlugin}{TempSensorEnabled} = '1';
The type (e.g. **SELECT** ) tells configure to how to prompt for the value. It also tells configure how to do some basic checking on the value you actually enter. All the comments between the type and the configuration item are taken as part of the description. The configuration item itself defines the default value for the configuration item. The above spec defines the configuration items $Foswiki::cfg{BathPlugin}{PlugType}, $Foswiki::cfg{BathPlugin}{ChainLength}, and $Foswiki::cfg{BathPlugin}{TempSensorEnabled} for use in your plugin. For example,
if( $Foswiki::cfg{BathPlugin}{TempSensorEnabled} && $curTemperature > 50 ) {
    die "The bathwater is too hot for comfort";
}

The Config.spec file is read by configure, and configure then writes LocalSite.cfg with the values chosen by the local site admin.

A range of types are available for use in Config.spec files:

BOOLEAN A true/false value, represented as a checkbox
COMMAND length A shell command
LANGUAGE A language (selected from {LocalesDir}
NUMBER A number
OCTAL An octal number
PASSWORD length A password (input is hidden)
PATH length A file path
PERL A simplified perl data structure, consisting of arrays, hashes and scalar values
REGEX length A perl regular expression
SELECT choices Pick one of a range of choices
SELECTCLASS package-specifier Select a perl package (class) e.g. SELECTCLASS Foswiki::Plugins::BathPlugin::*Plug lets the user select between all packages with names ending in Plug, Foswiki::Plugins::BathPlugin::RubberPlug, Foswiki::Plugins::BathPlugin::BrassPlug etc.
STRING length A string
URL length A url
URLPATH length A relative URL path

All types can be followed by a comma-separated list of attributes.

EXPERT means this an expert option
M means the setting is mandatory (may not be empty)
H means the option is not visible in configure

See lib/Foswiki.spec for many more examples.

Config.spec files are also used for other (non-plugin) extensions. in this case they are stored under the Contrib directory instead of the Plugins directory.

Maintaining Plugins

Discussions and Feedback on Plugins

Usually published plugins have a support hub in the Support web on Foswiki.org.Support hubs have links to where to discuss feature enhancements and give feedback to the developer and user communities.

Maintaining Compatibility with Earlier Foswiki Versions

The plugin interface (Foswiki::Func functions and plugin handlers) evolve over time. Foswiki introduces new API functions to address the needs of plugin authors. Plugins using unofficial Foswiki internal functions may no longer work on a Foswiki upgrade.

Organizations typically do not upgrade to the latest Foswiki for many months. However, many administrators still would like to install the latest versions of a plugin on their older Foswiki installation. This need is fulfilled if plugins are maintained in a compatible manner.

TIP Tip: Plugins can be written to be compatible with older and newer Foswiki releases. This can be done also for plugins using unofficial Foswiki internal functions of an earlier release that no longer work on the latest Foswiki codebase. Here is an example; the Foswiki:Support.PluginsSupplement has more details.

    if( $Foswiki::Plugins::VERSION >= 1.1 ) {
        @webs = Foswiki::Func::getListOfWebs( 'user,public' );
    } else {
        @webs = Foswiki::Func::getPublicWebList( );
    }

Handling deprecated functions

From time-to-time, the Foswiki developers will add new functions to the interface (either to Foswiki::Func, or new handlers). Sometimes these improvements mean that old functions have to be deprecated to keep the code manageable. When this happens, the deprecated functions will be supported in the interface for at least one more Foswiki release, and probably longer, though this cannot be guaranteed.

When a plugin defines deprecated handlers, a warning will be shown in the list generated by %FAILEDPLUGINS%. Admins who see these warnings should check Foswiki.org and if necessary, contact the plugin author, for an updated version of the plugin.

Updated plugins may still need to define deprecated handlers for compatibility with old Foswiki versions. In this case, the plugin package that defines old handlers can suppress the warnings in %FAILEDPLUGINS%.

This is done by defining a map from the handler name to the Foswiki::Plugins version in which the handler was first deprecated. For example, if we need to define the endRenderingHandler for compatibility with Foswiki::Plugins versions before 1.1, we would add this to the plugin:

package Foswiki::Plugins::SinkPlugin;
use vars qw( %FoswikiCompatibility );
$FoswikiCompatibility{endRenderingHandler} = 1.1;
If the currently-running Foswiki version is 1.1 or later, then the handler will not be called and the warning will not be issued. Foswiki with versions of Foswiki::Plugins before 1.1 will still call the handler as required.

TWiki® Plugins

Most plugins written for TWiki can also be run in Foswiki, by installing the TWikiCompatibilityPlugin. See Foswiki:Extensions.TWikiCompatibilityPlugin for more information.

CGI and Command Line Scripts

Programs on the server performing actions such as rendering, saving and renaming topics.

These scripts are located in the bin and tools directories. This topic describes the interfaces to some of those scripts. All scripts in the bin directory can be called from the CGI (Common Gateway Interface) environment or from the command line. The scripts in the tools directory can only be called from the command line.

CGI Scripts

Details on CGI scripts located in the bin directory.

General Information

CGI environment

In the CGI environment parameters are passed to the scripts via the URL and URL parameters. Environment variables are also used to determine the user performing the action. If the environment is not set up, the default user is used (usually guest).

Command-line

You must be have the bin directory on the perl path to run the scripts from the command line. To avoid issues with file permissions, run the scripts as the web server user such as nobody or www.

Parameters are passed on the command line using '-name' - for example,

$ cd /usr/local/foswiki/bin
$ save -topic MyWeb.MyTopic -user admin -action save -text "New text of the topic"
All parameters require a value, even if that is the empty string.

Common parameters

All the scripts accept a number of common parameters. The first two components of the URL after the script name are taken as the web and the topic, respectively. Standard URL parameters are:

Parameter Description Default
topic If this is set to a URL, STALklubben will immediately redirect to that URL. Otherwise it overrides the URL and is taken as the topic name (you can pass Web.TopicName)  
user Command-line only; set the name of the user performing the action. Note: this usage is inherently insecure, as it bypasses webserver login constraints. For this reason only authorised users should be allowed to execute scripts from the command line.  
skin Overrides the default skin path (see Skins)  
cover Specifies temporary skin path to prepend to the skin path for this script only (see Skins)  
t While the t parameter is not actively used by any scripts, it is used throughout the links like edit to ensure that the browser doesn't cache the reply. generally set to current time
logout requests the LoginManager to log the current user out. (happens at the begining of the request so will terminate any other operation requested)

attach

Despite the name, this script doesn't actually attach a file to a topic - for that, use upload. This script is part of the transactions sequence executed when a file is uploaded from the browser. it just generates the "new attachment" page for a topic.

Parameter Description Default
filename Name of existing attachment (if provided, this is a "manage attachment" action) none (in which case this is a "new attachment" action)

changes

Shows all the changes in the given web.

The changes script can receive one parameter:

Parameter Description Default
minor If 0, show only major changes. If 1, show all the changes (both minor and major) 0

The main difference between invoking this script and using WebChanges is that WebChanges is based on a %SEARCH%, while this script reads the changes file in each web, making it much faster.

NOTE: The result from changes script and the topic WebChanges can be different, if the changes file is deleted from a web. In particular, in new installations the changes script will return no results while the WebChanges topic will.

configure

configure is the browser script used for inspection of, and changes to, the site configuration. None of the parameters to this script are useable for any purpose except configure. See configure.

edit

The edit script understands the following parameters, typically supplied by HTML input fields:

Parameter Description Default
action Optional. Use the editaction template instead of the standard edit. If action=text, then hide the form. If action=form hide the normal text area and only edit the form. You can change the Edit/Edit Raw buttons to always append the action parameter in skins like Pattern and Classic by setting the topic or preference setting EDITACTION to the value text or form. To edit the topic once the EDITACTION is defined as form simply remove the action=form from the browser URL of the edit script and reload the edit window  
onlynewtopic If set, error if topic already exists  
onlywikiname If set, error if topic name is not a WikiWord  
templatetopic The name of the template topic, copied to get the initial content (new topic only)  
text Initial text for the topic  
topicparent The parent topic  
formtemplate Name of the form to instantiate in the topic. Overrides the form set in the templatetopic if defined. (will remove the form is set to 'none')  
contenttype Optional parameter that defines the application type to write into the CGI header. Defaults to text/html. May be used to invoke alternative client applications  
anyname Any parameter can passed to the new topic; if the template topic contains %URLPARAM{"anyname"}%, it will be replaced by its value  
breaklock If set, any lease conflicts will be ignored, and the edit will proceed even if someone is already editing the topic.  
redirectto If the user continues from edit to save, and if the save (or cancels the edit) process is successful, save will redirect to this topic or URL. The parameter value can be a TopicName, a Web.TopicName, or a URL.
Note: Redirect to a URL only works if it is enabled in configure (Miscellaneous {AllowRedirectUrl}).
 

Form field values are passed in parameters named 'field' - for example, if I have a field Status the parameter name is Status.

  1. The first sequence of ten or more X characters in the topic name will be converted on save to a number such that the resulting topic name is unique in the target web.

NOTE: most skins support the definition of EDIT_SKIN, which is used as the value of the cover parameter in edit URLs. This allows you to override the default edit skin on a web, topic or user basis.

login

Used for logging in with TemplateLoginManager.
Parameter Description Default
origurl URL that was being accessed when an access violation occurred. the login process will redirect to this URL if it is successful none
username username of user logging in none
password password of user logging in none

logon

Used for logging in when Web Server authentication is being used (e.g. ApacheLoginManager). The script does nothing; it is purely a placeholder for triggering the login process. The webserver will be set up to require a valid user to access this script, thus triggering the webserver login process.

manage

Performs a range of management functions.

ALERT! Note: The manage script can only be called via HTTP POST method. Make sure you specify method="post" if you call the manage script via a form action. It is not possible to call manage from an <A href link.

Parameter Description Default
action One of create, createweb, changePassowrd, resetPassword, bulkRegister, deleteUserAccount, editSettings, saveSettings, restoreRevision none

action=create

Alternative entry point for creation, via edit, of a new topic, used by screens that support several actions using manage.
Parameter Description Default
topic Name of topic to create (can be web.topic) none
Other parameters are the same as for edit.

action=createweb

Create a new web
Parameter Description Default
newweb Name of the new web ''
baseweb Name of the web to copy to create the new web ''
webbgcolor value for WEBBGCOLOR ''
sitemapwhat Value for SITEMAPWHAT ''
sitemapuseto Value for SITEMAPUSETO ''
nosearchall Value for NOSEARCHALL ''
newtopic Value of %TOPIC% within the web creation message. Optionally used in some skins to signify a non-default home topic.

action=editSettings

No parameters

action=saveSettings

Parameter Description Default
text Text of the topic ''
originalrev Revision that the edit started on Most recent revision
redirectto If the savesettings process is successful, save will redirect to this topic or URL. The parameter value can be a TopicName, a Web.TopicName, or a URL.
Note: Redirect to a URL only works if it is enabled in configure (Miscellaneous {AllowRedirectUrl}).
All other parameters may be interpreted as form fields, depending on the current form definition in the topic.

action=bulkRegister

See BulkRegistration.
Parameter Description Default
OverwriteHomeTopics Whether to overwrite existing home topics or not false
EmailUsersWithDetails Whether to mail registered users or not false
LogTopic Topic to save the log in Same as topic name, with 'Result' appended.

action=changePassword

Change password, email address, or both, of a user.
Parameter Description Default
username god alone knows none
oldpassword current password none
password new password none
passwordA new password confirmation none
email new email address none
password, =passwordA and email are optional. If neither or password and passwordA is set, then the user password is left unchanged. If email is unset, their email is left unchanged.

action=resetPassword

Reset the password for a single or multiple users
Parameter Description Default
LoginName list of usernames to reset none - error if not set
Introduction message to be sent alongside the reset, most often used to announce to the user that they have been given an account. ''

This is used by BulkResetPassword and ResetPassword. Only administrators can provide a list of LoginNames, non-admins can only provide a single LoginName.

BulkRegistration provides the means to create multiple accounts but it does not announce those accounts to the users who own them. BulkResetPassword is used to assign the passwords, the Introduction is used to explain why they are receiving the mail.

action=deleteUserAccount

Unregisters (removes) the currently logged-in user.
Parameter Description Default
password Users' password none

action=restoreRevision

Alternative entry point for edit, used by screens that support several actions using manage. Parameters are as for =edit.

oops

This script is mainly used for rendering pages containing error messages, though it is also used for some functional actions such as manage pages (move topic etc).

oops templates are used with the oops script to generate system messages. This is done to make internationalisation or other local customisations simple.

The oops script supports the following parameters:

Parameter Description Default
template Name of the template file to display  
def Optional, can be set to the name of a single definition within template. This definition will be instantiated in the template wherever %INSTANTIATE% is seen. This lets you use a single template file for many messages. For an example, see oopsmanagebad.tmpl.  
paramN Where N is an integer from 1 upwards. These values will be substituted into template for %PARAM1% etc.  

preview

This script is deprecated. Its functions are covered by the save script.

rdiff

Renders the differences between version of a topic

Parameter Description Default
rev1 the higher revision  
rev2 the lower revision  
render the rendering style {sequential, sidebyside, raw, debug} DIFFRENDERSTYLE, sequential
type {history, diff, last} history diff, version to version, last version to previous diff
context number of lines of context  
TODO:
  • add a {word} render style

register

Parameter Description Default
action register or verify or resetPassword or approve  

ALERT! Note: The register script can only be called via the HTTP POST method except when the action is verify. Make sure you specify method="post" if you call the register script via a form action. It is not possible to call register from an <A href link. The verify action is an exception as it is used to verify registration by clicking a href link from an email.

rename

Used for renaming webs, topics and attachments.

Parameter Description Default
action renameweb or anything else  
skin skin(s) to use  
confirm if defined, requires a second level of confirmation  
referring_topics (internal use only) list of topics that refer to the web or topic being renamed  
redirectto If the rename process is successful, rename will redirect to this topic or URL. The parameter value can be a TopicName, a Web.TopicName, or a URL.
Note: Redirect to a URL only works if it is enabled in configure (Miscellaneous {AllowRedirectUrl}).
 

action="renameweb"

Rename a web.
Parameter Description Default
newparentweb new parent web name existing parent
newsubweb new web name  

action=anything else

Rename a topic or an attachment.
Parameter Description Default
newweb new web name  
newtopic new topic name  
attachment Attachment to move none
template template for error when an attachment doesn't exist, deleteattachment for when deleting an attachment  
currentwebonly if defined, searches current web only for links to this topic  
nonwikiword if defined, a non-wikiword is acceptable for the new topic name  

ALERT! Note: The rename script can only be called via the HTTP POST method. Make sure you specify method="post" if you call the rename script via a form action. It is not possible to call rename from an <A href link.

rest

This REST (Representational State Transfer) script can be invoked via http in the same way as the other scripts (see Invocation Examples, below) to execute a function that is associated to a "subject" and a "verb" (see below). These functions are usually registered by plugins using the Foswiki::Func::registerRESTHandler method. The rest script will print the result directly to the browser unless the endPoint parameter is specified, in which case it will output a redirect to the given topic.

The rest script supports the following parameters:

username If TemplateLogin, or a similar login manager not embedded in the web server, is used, then you need to pass a username and password to the server. The username and password parameters are used for this purpose.
password See username
topic If defined as the full name (including web) of a topic, then when the script starts up plugins will be passed this as the "current" topic. If not defined, then Main.WebHome will be passed to plugins.
endPoint Where to redirect the response once the request is served, in the form "Web.Topic"

The function is free to use any other query parameters for its own purposes.

ALERT! The rest script should always require authentication in any site that has logins. Otherwise there is a risk of opening up major security holes. So make sure you add it to the list of authenticated scripts if you are using ApacheLogin.

Invocation Examples

The rest script assumes that it will be called with URL in the form:

http://my.host/bin/rest/<subject>/<verb>

where <subject> must be the WikiWord name of one of the installed Plugins, and the <verb> is the alias for the function registered using the Foswiki::Func::registerRESTHandler method. The <subject> and <verb> are then used to lookup and call the registered function.

<subject> and <verb> are checked for illegal characters exactly in the same way as the web and topic names.

As an example, the EmptyPlugin has registered a function to be used with the rest script under the subject EmptyPlugin and the verb example. Click below to see the rest script in action (run as guest).

Call the Plugin

Note that for Plugins to register REST handlers, they must be enabled in configure.

Retrieving passed values

Additional parameters can be recovered via the query object in the $session, for example with the url:
http://my.host/bin/rest/MyPlugin/update?web=foo

The url parameters can be processed using:

my $query = $session->{request};
my $web = $query->{param}->{web}[0];

save

The save script performs a range of save-related functions, as selected by the action parameter.

Parameter Description Default
action_save=1 default; save, return to view, dontnotify is off  
action_quietsave=1 save, and return to view, dontnotify is on  
action_checkpoint save and redirect to the edit script, dontnotify is on  
action_cancel exit without save, return to view  
action_preview preview edited text  
action_addform Redirect to the "change form" page.  
action_replaceform... Redirect to the "change form" page.  
action_delRev Administrators only delete the most recent revision of the topic - all other parameters are ignored. You have to be an administrator to use this, and not all store implementations will support it.  
action_repRev Administrators only replace the text of the most recent revision of the topic with the text in the text parameter. text must included embedded meta-data tags. All other parameters are ignored. You have to be an administrator to use this, and not all store implementations will support it.  
onlynewtopic If set, error if topic already exists  
onlywikiname If set, error if topic name is not a WikiWord  
dontnotify if defined, suppress change notification  
templatetopic Name of a topic to use as a template for the text and form (new topic only)  
text New text of the topic  
forcenewrevision if set, forces a revision even if STALklubben thinks one isn't needed  
topicparent If 'none' remove any current topic parent. If the name of a topic, set the topic parent to this.  
formtemplate if defined, use the named template for the form (will remove the form is set to 'none')  
editaction When action is checkpoint, add form or replace form..., this is used as the action parameter to the edit script that is redirected to after the save is complete.  
originalrev Revision on which the edit started.  
edit The script to use to edit the topic when action is checkpoint edit
editparams The parameter string to use to edit the topic  
redirectto The save process will redirect to this topic or URL if it is successful. (Typically this would be the URL that was being viewed when edit was invoked). The parameter value can be a TopicName, a Web.TopicName, or a URL.
Note: Redirect to a URL only works if it is enabled in configure (Miscellaneous {AllowRedirectUrl}).
view topic being edited

Any errors will cause a redirect to an oops page.

The parameters are interpreted in according to the following rules.

  1. The first sequence of ten or more X characters in the topic name will be converted to a number such that the resulting topic name is unique in the target web.
  2. When the action is save, checkpoint, quietsave, or preview:
    1. The new text is taken from the text parameter, if it is defined,
      • otherwise it is taken from the templatetopic, if it is defined, (new topic only)
      • otherwise it is taken from the previous version of the topic, if any,
    2. The name of the new form is taken from the formtemplate, if defined
      • otherwise it is taken from the templatetopic, if defined, (new topic only)
      • otherwise it is taken from the previous version of the topic, if any,
      • otherwise no form is attached.
    3. The value for each field in the form is taken from the query, if it is defined
      • otherwise it is taken from the templatetopic, if defined, (new topic only)
      • otherwise it is taken from the previous version of the topic, if any,
      • otherwise it defaults to the empty string.

Merging is only enabled if the topic text comes from text and originalrev is > 0 and is not the same as the revision number of the most recent revision. If merging is enabled both the topic and the meta-data are merged.

Form field values are passed in parameters named 'field' - for example, if I have a field Status the parameter name is Status.

ALERT! Note: The save script can only be called via HTTP POST method. Make sure you specify method="post" if you call the save script via a form action. Example:

<form name="new" action="%SCRIPTURLPATH{save}%/Sandbox/" method="post">
    ...
</form>
It is not possible to call save from an <A href link.

statistics

Refresh the WebStatistics topics in range of webs.
Parameter Description Default
webs comma-separated list of webs to run stats on all accessible webs
logdate YYYYMM to generate statistics for current month

for example:

  1. from browser http://www.stalklubben.org/foswiki/bin/statistics updates all user webs
  2. from browser http://www.stalklubben.org/foswiki/bin/statistics?webs=Userweb,Sandbox updates Userweb,Sandbox
  3. from browser http://www.stalklubben.org/foswiki/bin/statistics/System updates System
  4. from command line bin/statistics updates all user webs
  5. from command line bin/statistics -webs=Userweb,Sandbox updates Userweb,Sandbox
  6. from command line bin/statistics System.WebHome updates System

see SiteTools#WebStatistics_site_statistics for updating statistics using cron.

upload

Uploads an attachment to a topic. The HTTP request is expected to be in multipart/form-data format.
Parameter Description Default
hidefile if defined, will not show file in attachment table  
filepath local (client) path name of the file being uploaded. This is used to look up the data for the file in the HTTP query.  
filename deprecated, do not use  
filecomment Comment to associate with file in attachment table  
createlink if defined, will create a link to file at end of topic  
changeproperties if defined, this is a property change operation only - no file will be uploaded. null
redirectto URL to redirect to after upload. {AllowRedirectUrl} must be enabled in configure. The parameter value can be a TopicName, a Web.TopicName, or a URL. Redirect to a URL only works if it is enabled in configure, and is ignored if noredirect is specified.
Note: Redirect to a URL only works if it is enabled in configure (Miscellaneous {AllowRedirectUrl}).
noredirect Normally it will redirect to 'view' when the upload is complete, but also designed to be useable for REST-style calling using the 'noredirect' parameter. If this parameter is set it will return an appropriate HTTP status code and print a message to STDOUT, starting with 'OK' on success and 'ERROR' on failure.

Tips

  • You can use a tool like curl to upload files from the command line using this script.
  • You can call upload easily from XmlHttpRequest in Javascript.

ALERT! Note: The upload script can only be called via HTTP POST method. Make sure you specify method="post" if you call the upload script via a form action. It is not possible to call upload from an <A href link.

view

Used for viewing topics.

Parameter Description Default
raw=on Shows the text of the topic in a scrollable textarea  
raw=debug As raw=on, but also shows the metadata (forms etc) associated with the topic.  
raw=text Shows only the source of the topic, as plain text (Content-type: text/plain). Only shows the body text, not the form or other meta-data.
raw=all Shows only the source of the topic, as plain text (Content-type: text/plain), with embedded meta-data. This may be useful if you want to extract the source of a topic to a local file on disc.  
section Allows to view only a part of the topic delimited by a named section (see System.VarSTARTSECTION). If the given section is not present, no topic content is displayed.  
contenttype Allows you to specify a different Content-Type: (e.g. contenttype=text/plain)  
rev Revision to view (e.g. rev=45)  
template Allows you to specify a different skin template, overriding the 'view' template the view script would normally use. The default template is view. For example, you could specify /foswiki/bin/view/System/CommandAndCGIScripts?template=edit. This is mainly useful when you have specialised templates for a Wiki Application.  
topic redirects (at the beging of the cgi script running) to show the spcified Web.Topic, or, redirects to a URL, if allowed by {AllowRedirectUrl} and {PermittedRedirectHostUrls}  

ALERT! For historical reasons, the view script has a special interpretation of the text skin. This skin cannot be redefined.

viewfile

Used for viewing attachments. Normally, a site will publish the attachments (pub) directory using a URL. However if it contains sensitive information, you will want to protect attachments using AccessControls. In this case, you can use the viewfile script to give access to attachments while still checking access controls.

Parameter Description Default
filename name of attachment  
rev Revision to view  

Instead of using the filename parameter, you can append the attachment name to the end of the URL path (after the topic) e.g. http://www.stalklubben.org/foswiki/bin/viewfile/Webname/TopicName/Attachment.gif

Command Line Scripts

Details on command line scripts located in the tools directory.

geturl.pl

This is a very simple script to get the content of a web site. It is marked as deprecated and might be removed (or enhanced) in a future release. Its functions are covered by the standard wget and curl commands.
  • Usage: geturl.pl <host> <path> [<port> [<header>]]
  • Example: geturl.pl some.domain /some/dir/file.html 80
  • Will get: http://some.domain:80/some/dir/file.html

rewriteshebang.pl

Simple script to rewrite the #!/usr/bin/perl shebang lines specific to your local Perl installation. It will rewrite the first line of all your cgi scripts so they use a different shebang line. Use it if your perl is in a non-standard location, or you want to use a different interpreter (such as 'speedy').

tick_foswiki.pl

This script executes a number of non-essential regular administration tasks that will help keep your site healthy and happy, such as removing expired sessions and lease files.

It is intended to be run as a cron job or a scheduled task once a week. Example crontab entry:
0 0 * * 0 cd /usr/local/foswiki/bin && perl ../tools/tick_foswiki.pl

Note: The script has to be run by a user who can write files created by the webserver user.

Site Tools

Utilities for searching, navigation, and monitoring site activity

Site Tools include utilities for navigating, searching and keeping up with site activity.

In particular, you have two highly configurable, automated site monitoring tools, WebNotify, to e-mail alerts when topics are edited, and WebStatistics, to generate detailed activity reports.

WebNotify - recent changes alert

► Notification help▼ Notification help

Web Changes Notification Service

Each Foswiki web has an automatic e-mail notification service that sends you an e-mail with links to all of the topics modified since the last alert.

Users subscribe to email notifications using their WikiName or an alternative email address, and can specify the webs/topics they wish to track, Whole groups of users can also be subscribed for notification.

The general format of a subscription is:

three spaces * subscriber [ : topics ]

Where subscriber can be a WikiName, an E-mail address, or a group name. If subscriber contains any characters that are not legal in an email address, then it must be enclosed in 'single' or "double" quotes.

topics is an optional space-separated list of topics:

  • ... without a Web. prefix
  • ...that exist in this web.
Users may further customize the specific content they will receive using the following controls:
  • Using wild-card character in topic names - You can use * in a topic name, where it is treated as a wildcard character. A * will match zero or more other characters - so, for example, Fred* will match all topic names starting with Fred, *Fred will match all topic names ending with Fred, and * will match all topic names.
  • Unsubscribing to specific topics - Each topic may optionally be preceded by a '+' or '-' sign. The '+' sign means "subscribe to this topic". The '-' sign means "unsubscribe" or "don't send notifications regarding this particular topic". This allows users to elect to filter out certain topics. Topic filters ('-') take precedence over topic includes ('+') i.e. if you unsubscribe from a topic it will cancel out any subscriptions to that topic.
  • Including child-topics in subscription - Each topic may optionally be followed by an integer in parentheses, indicating the depth of the tree of children below that topic. Changes in all these children will be detected and reported along with changes to the topic itself. Note This uses the Foswiki "Topic parent" feature.
  • Subscribing to entire topic ("news mode") - Each topic may optionally be immediately followed by an exclamation mark ! and/or a question mark ? with no intervening spaces, indicating that the topic (and children if there is a tree depth specifier as well) should be mailed out as complete topics instead of change summaries. ! causes the full topic to be mailed every time even if there have been no changes, and ? will mail the full topic only if there have been changes. One can limit the content of the subscribed topic to send out by inserting %STARTPUBLISH% and %STOPPUBLISH% markers within the topic. Note that the script mailnotify can be run with the options -nochanges or -nonews so that you can run the two mode on different schedules (see details).

Examples: Subscribe Daisy to all changes to topics in this web.

   * daisy.cutter@flowers.com
Subscribe Daisy to all changes to topics that start with Web.
   * daisy.cutter@flowers.com : Web*
Subscribe Daisy to changes to topics starting with Petal, and their immediate children, WeedKillers and children to a depth of 3, and all topics that match start with Pretty and end with Flowers e.g. PrettyPinkFlowers
   * DaisyCutter: Petal* (1) WeedKillers (3) Pretty*Flowers
Subscribe StarTrekFan to changes to all topics that start with Star except those that end in Wars, sInTheirEyes or shipTroopers.
   * StarTrekFan: Star* - *Wars - *sInTheirEyes - *shipTroopers
Subscribe Daisy to the full content of NewsLetter whenever it has changed
   * daisy@flowers.com: NewsLetter?
Subscribe buttercup to NewsLetter and its immediate children, even if it hasn't changed.
   * buttercup@flowers.com: NewsLetter! (1)
Subscribe GardenGroup (which includes Petunia) to all changed topics under AllnewsLetters to a depth of 3. Then unsubscribe Petunia from the ManureNewsLetter, which she would normally get as a member of GardenGroup:
   * GardenGroup: AllNewsLetters? (3)
   * petunia@flowers.com: - ManureNewsLetter
Subscribe IT:admins (a non-Foswiki group defined by an alternate user mapping) to all changes to Web* topics.
   * 'IT:admins' : Web*

A user may be listed many times in the WebNotify topic. Where a user has several lines in WebNotify that all match the same topic, they will only be notified about changes that topic once (though they will still receive individual mails for news topics).

If a group is listed for notification, the group will be recursively expanded to the e-mail addresses of all members.

__ALERT! Warning: Because an email address is not linked to a user name, there is no way for Foswiki to check access controls for subscribers identified by email addresses. A subscriber identified by an email address alone will only be sent change notifications if the topic they are subscribed to is readable by guest users. You can limit what email addresses can be used in %NOTIFYTOPIC%, or even block use of emails altogther, using the {MailerContrib}{EmailFilterIn} setting in =configure.

TIP Tip: List names in alphabetical order to make it easier to find the names.

Note for System Administrators: Notification is supported by an add-on to the Foswiki kernel called the MailerContrib. See the MailerContrib topic for details of how to set up this service.

Note: If you prefer a news feed, point your reader to WebRss (for RSS 1.0 feeds) or WebAtom (for ATOM 1.0 feeds). Learn more at WebRssBase and WebAtomBase, respectively.

WebSearch - search the site

WebSearch is a flexible search facility, part of the core feature set. WebSearchAdvanced offers more options, including:

  • topic title or full-text search
  • regular expressions
  • query search over form data
  • search within web or site-wide
  • index-style A-Z alphabetical listing sorted topic title
  • many more

See also: SearchHelp for help; Macros and FormattedSearch for including hard-coded searches in text.

WebChanges - what's new

To check for the most recently edited topics while on-site, use the WebChanges link, usually located in the toolbar. It lists the most recently modified topics, newest first, along with the first couple of lines of the page content.

This is simply a preset SEARCH. The number of topics listed by the limit parameter.:

%SEARCH{ ".*" web="System" type="regex" nosearch="on" order="modified"
reverse="on" limit="50" }%

WebRss and WebAtom - news feeds on recent changes

You can point your news reader at WebRss and WebAtom to find out what is new in a web. WebRssBase and WebAtomBase have the details. Like WebChanges, this is based on a %SEARCH{}%.

WebIndex - list of topics

WebIndex lists all web topics in alphabetical order, with the first couple of lines of text. This is simply a preset SEARCH:

%SEARCH{ "\.*" scope="topic" type="regex" nosearch="on" }%

WebStatistics - site statistics

You can generate a listing manually, or on an automated schedule, of visits to individual pages, on a per web basis. Compiled as a running total on a monthly basis. Includes totals for Topic Views, Topic Saves, Attachment Uploads, Most Popular Topics with number of views, and Top Contributors showing total of saves and attachment uploads. Previous months are saved.

  • You can create a WebStatistics link using %STATISTICSTOPIC%

Configuring for automatic operation

  • You can automatically generate usage statistics for all webs. To enable this:
    • Make sure configure settings {Log}{view}, {Log}{save} and *{Log}{upload} in are set in configure. This will generate log file entries (see below).
    • The WebStatistics topic must be present in all webs where you want to have statistics. You can use the topic in the Main web as a template.
    • Call the bin/statistics script from a cron job, once a day is recommended. This will update the WebStatistics topics in all webs.
    • Attention: The script must run as the same user as the CGI scripts are running, which is user nobody on many systems. Example crontab entry:
      0 0 * * * (cd /path/to/bin; ./statistics >/dev/null 2>&1)
    • There is a workaround in case you can't run the script as user nobody : Run the utility tools/geturl.pl in your cron job and specify the URL of the bin/statistics script as a parameter. Example:
      0 0 * * * (cd /path/to/tools; ./geturl.pl mydomain.com /urlpath/to/bin/statistics >/dev/null 2>&1)
    • NOTE: geturl.pl will do a CGI request as the WikiGuest user, so if you use this workaround, the WebStatistics topics you are updating will have to be writable by WikiGuest.

When running from the command line or a cron job, you can pass parameters to the script like this:

./statistics -logdate 200605 -webs Userweb,Sandbox

Generating statistics manually by URL

  • The bin/statistics script can also be executed as a CGI script, just enter the URL in your browser. Examples:
    • Update current month for all webs you have access to:
      /foswiki/bin/statistics
    • Update current month for Main web only:
      /foswiki/bin/statistics/Main
    • Update Mar 2024 for Main web:
      /foswiki/bin/statistics/Main?logdate=202403
    • Update Mar 2024 for the ProjectX, ProjectY and ProjectZ webs:
      /foswiki/bin/statistics?logdate=202403;webs=ProjectX,ProjectY,ProjectZ

Log Files

Foswiki generates monthly log files which are used by the statistics script

  • The log file is defined by the {LogFileName} setting in configure
  • The file name is log<year><month>.txt
  • Example path name: logs/log202403.txt
  • Each access gets logged as:
    | <time> | <wikiusername> | <action> | <web>.<topic> | <extra info> | <IP address> |
  • Example log entry:
    | 19 Mar 2024 - 04:10 | Main.WikiGuest | view | System.WebRss |  | 66.124.232.02 |
  • Actions are logged if enabled in configure by the {Log}{action} flags
  • Logged actions:
    Script Action name Extra info
    attach attach when viewing attach screen of previous uploaded attachment: filename
    changes changes  
    edit edit when editing non-existing topic: (not exist)
    rdiff rdiff higher and lower revision numbers: 4 3
    register regstart WikiUserName, e-Mail address, LoginName: user attempts to register
    register register E-mail address: user successfully registers
    register bulkregister WikiUserName of new, e-mail address, admin ID
    manage rename when moving topic: moved to Newweb.NewTopic
    manage move when moving attachment: Attachment filename moved to Newweb.NewTopic
    manage renameweb when renaming a web: oldweb moved to newweb
    save save when replacing existing revision: repRev 3
    when user checks the minor changes box: dontNotify
    when user changes attributes to an exising attachment: filename.ext
    save cmd special admin parameter used when saving
    search search search string
    upload upload filename
    view view when viewing non-existing topic: (not exist)
    when viewing previous topic revision: r3

E-mail

Configuring outgoing mail

Outgoing mail is required for UserRegistration and for recent changes alert.

Foswiki will use the Net::SMTP module if it is installed on your system. Set this with the SMTPMAILHOST preference setting.

The notify e-mail uses the default changes.tmpl template, or a skin if activated by a preference setting.

mailnotify also relies on two hidden files in each data/Web directory: .changes and .mailnotify. Make sure both are writable by your web server process. .changes contains a list of changes; go ahead and make this empty. .mailnotify contains a timestamp of the last time notification was done.

You can use an external mail program, such as sendmail, if the Net::SMTP module is not installed. Set the program path in {MailProgram} in configure.

! * HELP Net::SMTP can be easily disabled (if there is an installation error) by setting the SMTPMAILHOST preference setting to an empty value.

  • TIP You can set a separate SMTPSENDERHOST preference setting to define the mail sender host (some SMTP installations require this).

Setting the automatic e-mail schedule

For Unix platforms: Edit the cron table so that mailnotify is called in an interval of your choice. Please consult man crontab of how to modify the table that schedules program execution at certain intervals. Example:

% crontab -e
0 1 * * * (cd /path/to/bin; ./mailnotify -q)
The above line will run mailnotify nightly at 01:00. The -q switch suppresses all normal output.

For ISP installations: Many ISPs don't allow hosted accounts direct cron access, as it's often used for things that can heavily load the server. Workaround scripts are available.

On Windows: You can use a scheduled task if you have administrative privileges.

Site Permissions

  • AccessControl describes how to restrict read and write access to topics and webs, by users and groups
  • SitePermissions lists the permissions settings of the webs on this site

Help with crontab

The crontab command is used to schedule commands to be executed periodically.

Managing Topics

Browser-based rename, move, and delete for individual topics

Overview

You can use browser-based controls to change a name of a topic, move it to another web or delete it to a hidden Trash web.

How to rename, move or delete a topic

  1. Select the [More actions] link (normally located in an action toolbar at the top or bottom of page) on the topic to be changed. Then, in the new screen, click [Rename, move or delete this topic]. You can now rename and/or move/delete in one operation:
    • Move/Delete: Select the target web if other than the current web - choose Trash to delete a topic.
    • Rename: Enter the new topic name - default is current name
      ALERT! You'll be warned if any of the topics to be affected are locked (being edited), or if there is a name conflict.
  2. Prevent updates by unchecking individual items on the list of referring links - these topics will NOT to be updated with the new name (by default, only links in the same web will be updated).
  3. Click on [Rename]: the topic will be renamed and links to the topic updated as requested.
    • If any of the referring pages are locked then they will be listed: you can correct these later by again pressing [Rename].
    • HELP There is a Put back feature that allows you to undo a rename/move/delete action - an instruction line and an undo link will appear at the bottom of the modified topic. This allows you to revert from the last modification only.

How to copy a topic

  1. Select the [More actions] link (normally located in an action toolbar at the top or bottom of page) on the topic to be changed.
  2. On the "More actions" page, scroll down to the "Copy topic" section. In the "Name of copy" text box, enter in the new topic name. To copy the topic to another web, fully qualify the topic name with the web name, separating the two with a period (for example, Web.TopicName).
  3. Select the [Copy topic] button. You will be directed to an edit page for the newly-created topic. You can save the new copy immediately, or make some changes and then save it.

Deleted topics: How to clear the trash

Deleted topics are moved to a special Trash web - they are NOT physically erased from the server. All webs share the same Trash - in case of a name conflict with a topic already existing in the Trash web, the user is alerted and asked to choose a new name.

The Trash web should be be cleared periodically, by archiving (saving) the text and RCS files if required (recommended), then deleting them from the Trash directory.

  • ALERT! This can only be done from on the server, not through the browser.
    • TIP Since simple FTP access to the Trash directory is all that is required for maintenance, it is possible to grant Trash admin privileges to multiple users, while strictly limiting server access.

Redirecting from an old topic

You can use MetaData to place a command in the System.TopicDoesNotExistViewTemplate that will indicate that a topic has been moved by searching for the tag %META:TOPICMOVED{...}%. Customize something like this:

%<nop>METASEARCH{type="topicmoved" web="%WEB%" topic="%TOPIC%" 
title="This topic used to exist and was moved to: "}%

How rename/move works

  1. %SEARCH%, with a special template, finds and displays all occurrences of the topic name in other topics, either web- or site-wide. These referring links are by default automatically changed to the new topic and/or web name. This includes relevant MetaData definitions.
    • User can omit one or more topics from the update list by unchecking them.
    • <pre> and <verbatim> are honoured - no changes are made to text within these areas.
  2. The topic is moved (if locks allow).
  3. References are changed (locks and permissions permitting).
  4. Any referring topics that cannot be changed due to locks are listed - user can take note and change them at another time.

How referring topics are found

First, matching topics in the current web are listed - matches are to topic. Next, all webs (including the current one) are listed that match web.topic. All webs will be searched during rename, even if NOSEARCHALL is defined on a web, though access permissions will of course be honoured.

Changed references are kept as short as possible, ex: topic is used in preference to web.topic.

Effect of user access settings

User permissions affect the 'rename' functions in various ways. To rename a topic, you need all of VIEW, CHANGE and RENAME access to that topic. To alter referring topics, you need CHANGE access. See AccessControl for information on setting up access permissions.

Special considerations

Consider carefully whether to make browser-based rename/move/delete widely available, or to restrict it to an administrator/moderator group. Allowing all users to easily manipulate topics can be extremely useful in refactoring a busy web or site. However, there are at least two significant potential drawbacks to take into account:

  1. When referring links are updated, the modified topics appear in WebChanges, creating the impression that editorial changes were made. This can undermine the usefulness of WebChanges.
  2. Due to current limitations, fairly heavy use of rename/move/delete functions can lead to an accumulation of minor technical problems (ex: broken links) and usability issues (ex: user confusion). If rename... is used heavily, these negatives will obviously increase, in number and effect.

Ultimately, the size, objectives, and policies of your site, the real-world behavior of your user group, and most importantly, the initial Foswiki site management leadership, will determine the most effective implementation of this feature, and the success of the site overall.

Known issues

Rename/move is fairly complicated due to the dynamic generation of links. Ideally, it would be possible to run the required part of rendering in a way that would allow identification of the text to be changed. Unfortunately, these hooks don't exist at present. Instead, %SEARCH% is used with a special template to show the text to be changed, and the selected topics are then altered. One drawback is that search can show matches that will not be updated due to case differences. Other mismatches with actual rendered output are also possible as the approaches are so different.

The following shows some limitations of square bracket processing.

[[Old Topic]]  => [[NewTopic][Old Topic]]
[[old topic]]  => [[NewTopic][old topic]]
[[old t opic]] => not changed
[[OldTopic]]   => [[NewTopic]]

Managing Webs

What are Webs?

A Foswiki site is divided into "Webs", or groups or topics - each one represents one subject, one area of collaboration. Administrators can add, rename or delete webs.
At file level, a Web is a directory located inside the data directory, with text files as topics.
A number of Webs are fixed: System for documentation, Main to store user pages and site-wide preferences, Trash for the topic recycle bin.
Other webs can be created as needed.

Webs on this site

Main
  • Welcome to STALklubben... Users, Groups
  • Used to: ...see who is registered on this site

Create a new web

To use this form you must be administrator.

Before you begin: consider that less webs are better than more webs. Cross-linking topics is easier, and searches are faster, if there are only a few larger webs.

Name of the new Web Required

Naming rule: the name must start with an upper case letter, followed by upper or lower case letters or numbers. Examples: Learn, SupDocs, KNow3

If you are creating a nested web (a web inside a web), use the notation Existingweb.Newweb.
+ More info about nested webs ...− Close info

About hierarchical webs

You can only create hierarchical webs if the {EnableHierarchicalWebs} setting in configure is enabled. Hierarchical webs are currently enabled .

You might not need hierarchical webs. Foswiki topics already have a parent/child relationship within a web, which is shown in the breadcrumb. Try to keep the number of webs to a minimum in order to keep search and cross-referencing simple.


Description

Enter a short description of the web. This description will be used in the SiteMap. If you are using links: write Web.TopicName instead of just TopicName for correct linking.


+ Show additional settings...− Hide additional settings

Template web

Base the new web on an existing web.
+ More info about template webs ...− Close info

About template webs

There are two methods used to create a new web.
First you can use a specially designed TemplateWeb. This is an invisible web that begins with an underscore "_" character (for example _default). All topics in the template web will be copied into your new web.
The second method is to use an existing web as a template web. This may be useful if you already have a web that you would like to use as a starting point. Only topics that have names beginning with "Web..." (like "WebHome" or "WebNotify") are copied. In either case you will want to be sure to verify that your new web has all the custom modifications that you desire.

Notes:

  • You must have ROOTCHANGE access to create a top-level web (one with no parent)
  • A new web created using the _default or _empty template webs must have their access controls set before public use
  • Only the person who created it has permission to change the WebPreferences in the new web


List on SiteMap page

Should the new web be listed on SiteMap (see #SiteMap above)? Even if hidden, the web will be linkable and accessible to users.


Include in global search

Specify if you want to exclude the web from a global search.


Web color

Displayed on SiteMap and in the left bar (Pattern Skin).


In-depth info on Webs

Subweb preferences are inherited

The preference settings of a subweb are inherited from the parent web and overridden locally. Preferences are ultimately inherited from the System.DefaultPreferences topic.

Example Preference Inheritance for Sandbox/TestWeb/SubWeb.SubWebTopic topic:

  1. System.DefaultPreferences default settings
  2. Main.SitePreferences site-wide settings inherits from and overrides settings in System.DefaultPreferences
  3. Sandbox.WebPreferences inherits from and overrides settings in Main.SitePreferences
  4. Sandbox/TestWeb.WebPreferences inherits from and overrides settings in Sandbox.WebPreferences
  5. Sandbox/TestWeb/SubWeb.WebPreferences inherits from and overrides settings in Sandbox/TestWeb.WebPreferences
  6. Sandbox/TestWeb/SubWeb.SubWebTopic inherits from and overrides settings in Sandbox/TestWeb/SubWeb.WebPreferences

Subweb navigation

The Pattern skin (default) indicates Subwebs by indenting them in the sidebar relative to their level in the hierarchy.

Renaming or Deleting a Web

Rename a web via the Tools section in each WebPreferences topic. You may delete a web by moving it into a Trash web.

Permissions

You may only rename a web if you have the following permissions
  • You must be allowed to rename and changes topics in the web you want to rename
  • You must be allowed to rename topics in the parent web of the web you want to rename
  • If the web is a root web (i.e. it has no parent web) then you must have permission to both create and rename root webs. These permissions are controlled by the ALLOWROOTCHANGE preference, which can be set in Main.SitePreferences.
  • If you move the web to another parent web you must be allowed to create and change topics in the new parent web. When you rename a web Foswiki will try and update all links that refer to the old web. You should note that links only get updated in topics that you are allowed to edit. If you use access rights in the Foswiki installation it is generally best to let an administrator rename webs to avoid too many broken links.

Renaming the webs in the distribution

It is possible, though not recommended, to change the names of the webs in the distribution. If you plan to rename the Main web, remember that Foswiki stores user topics in this web. That means that every WikiName signature - Main.SomeUserName - points to it and would need updating (unless the macro style %USERSWEB%.SomeUserName, is used throughout). This potentially large change can be performed automatically if you rename the web from the Tools section of WebPreferences, as described above.

ALERT! If you want to rename the System or Main webs, remember they are referred to in the Foswiki configuration. You will need to change the {SystemWebName}, {UsersWebName} and/or {LocalSitePreferences} settings in the configuration using the configure interface.

ALERT! Renaming the webs in the distribution is not recommended because it makes upgrades much more complicated.

Manage Users

Register users on your Foswiki site; change/reset/install passwords; remove user accounts

ALERT! Some of the features below may be disabled, depending on your Foswiki configuration.

Authentication and Access Control

  • UserAuthentication describes your options for user authentication
  • AccessControl describes how to define groups and how to restrict access to content

Register User

You don't have to have user home pages in Foswiki for Authentication to work - see UserAuthentication for details.

  • UserRegistration is used when you want new users to individually register with Foswiki by filling out a form
  • You can create a custom versions of System.NewUserTemplate and System.UserForm
  • BulkRegistration is used by administrators to register multiple users at the same time

Change, Reset and Install Passwords

Note that the below features are only relevant when you use an internal password manager where Foswiki can set and reset passwords.

  • ChangePassword is for users who can remember their password and want to change it
  • ResetPassword is for users who cannot remember their password; a system generated password is e-mailed to them
  • BulkResetPassword is for administrators who want to reset many passwords at once
  • ChangeEmailAddress changes the hidden email address stored in the password file

Changing User Account Names

To change the user's WikiName:

  • Rename the user's Foswiki homepage in the Main web, such as from JaneSmith to JaneMiller.
    • Fix backlinks in the Main web only
    • Make sure the group topics are updated (if any.)
  • Edit the Main.WikiUsers topic and move the user's entry so that the list is in proper alphabetical order.
  • Recreate the old topic with a pointer to the new topic, so that links in other webs work properly. Example content:
    %M% Jane Smith is now known as JaneMiller

If external authentication is used and you want to change the login name:

  • The login name needs to be changed in the authentication server (e.g. Active Directory)
  • In Foswiki's Main.WikiUsers topic, fix the mapping from login name to WikiName:
       * JaneSmith - jsmith - 13 Sep 2006
    to:
       * JaneMiller - jmiller - 13 Sep 2006

Removing User Accounts

To remove a user account (FredQuimby, who logs in as "fred"):

  1. If you are using a .htpasswd file, edit the .htpasswd file to delete the line starting fred:
    • Warning: Do not use the Apache htpasswd program with .htpasswd files generated by Foswiki! htpasswd wipes out email addresses that Foswiki plants in the info fields of this file.
  2. Remove the FredQuimby - fred line from the Main.WikiUsers topic
  3. Remove FredQuimby from all groups and from all the ALLOWWEB/ALLOWTOPIC... declarations, if any.
    Note: If you fail to do this you risk creating a security hole, as the next user to register with the wikiname FredQuimby will inherit the old FredQuimby's permissions.
  4. [optional] Delete their user topic Main.FredQuimby (including attachments, if any.)

Note: Consider leaving the user topic file in place so their past signatures and revision author entries don't end up looking like AnUncreatedTopic. If you want to make it clear the user is no longer around, replace the topic content with a note to that effect. The existence of the UserName topic should also prevent that user name from being re-used, sealing the potential security hole regarding inherited permissions..

Customizing registration Emails.

Foswiki's Registration can send 3 emails who's output is governed by templates:
  1. User registration confirmation - templates/registerconfirm.tmpl
  2. User registration notification - templates/registernotify.tmpl
  3. Email to notify the Wiki admin of registration - templates/registernotifyadmin.tmpl

As these are SkinTemplates, they can be customized and selected using the SKIN path setting. Because there are default tmpl files in the templates dir, this cannot use Template topics.

These template files have a specific format that matches the raw format of emails sent via SMTP, so be careful and test your changes. It is easiest to start by copying the default templates:

cd templates
cp registernotify.tmpl registernotify.myskin.tmpl
cp registerconfirm.tmpl registerconfirm.myskin.tmpl
cp registernotifyadmin.tmpl registernotifyadmin.myskin.tmpl
then add myskin to the beginning of the SKIN setting in Main.SitePreferences.

From this point on, your myskin templates will be used for the registration emails.

To make it possible for WikiUsers to modify the email contents, you could use a parameterized %INCLUDE% statement in your customized version. eg:

From: %WIKIWEBMASTERNAME% <%WIKIWEBMASTER%>
To: %FIRSTLASTNAME% <%EMAILADDRESS%>
Subject: %MAKETEXT{"[_1] - Registration for [_2] ([_3])" args="%WIKITOOLNAME%, %WIKINAME%, %EMAILADDRESS%"}%
MIME-Version: 1.0
Content-Type: text/plain; charset=%CHARSET%
Content-Transfer-Encoding: 8bit

%INCLUDE{
    "%USERSWEB%.RegisterNotifyEmail"
    WIKINAME="%WIKINAME%"
    FIRSTLASTNAME="%FIRSTLASTNAME%"
    EMAILADDRESS="%EMAILADDRESS%"
}%
  • note the use of %WIKINAME%, %FIRSTLASTNAME%, %EMAILADDRESS% passed in from the INCLUDE so that the topic below is similar to the original template

and then create a topic Main.RegisterNotifyEmail:

Welcome to %WIKITOOLNAME%.

%MAKETEXT{"Your personal [_1] topic is located at [_2]. You can customize it as you like:" args="%WIKITOOLNAME%, %SCRIPTURL{"view"}%/%USERSWEB%/%WIKINAME%"}%

   * %MAKETEXT{"Some people turn it into a personal portal with favorite links, what they work on, what help they'd like, etc."}%
   * %MAKETEXT{"Some add schedule information and vacation notice."}%

Regards
%WIKIWEBMASTERNAME%
Your Wiki Admin


%MAKETEXT{"Note:"}%
   2 %MAKETEXT{"You can change your password at via [_1]" args="%SCRIPTURL{"view"}%/%SYSTEMWEB%/ChangePassword"}%
   3 %MAKETEXT{"If you haven't set a password yet or you want to reset it, go to: [_1]" args="%SCRIPTURL{"view"}%/%SYSTEMWEB%/ResetPassword"}%

%MAKETEXT{"Submitted content:"}%
%FORMDATA%

  • remember to secure the topic appropriately to prevent attackers from getting emailed sensitive passwords.

Foswiki Release 1.0.0 - 09 Jan 2009

Foswiki is the old TWiki project under a new name. Restrictions on the use of the TWiki brand resulted in many of its developers continuing the project under the new Foswiki name. Foswiki is backwards compatible with all content from older TWiki installations. Foswiki 1.0.0 ships with a TWikiCompatibilityPlugin installed and activated by default, thus enabling most extensions made for TWiki to work under Foswiki.

New features and enhancements

  • Foswiki 1.0.0 is built on a new platform called Foswiki Stand Alone which adds support for FastCGI and enables more optimized functionality in mod_perl and other similar runtime environments. Foswiki Stand Alone also enables future features such as running Foswiki by itself without a separate web server (for example, from a stand alone memory key). You can ensure your applications and plugins will work properly on the new platform (and thus with any future capabilities dependent on the new architecture) by testing them out now with Foswiki 1.0.0.
  • A TWikiCompatibilityPlugin has been created that enables most extensions made for TWiki to work under Foswiki, and to support seamless migrations from TWiki to Foswiki.
  • The PatternSkin has been given a facelift: The PatternSkin topic offers a choice of multiple themes, the sidebar can be placed either on the left or right, a frame can be added around the main content area, and a TWiki theme is available to make it easier for those upgrading from TWiki (dimensions such as the top bar size match the dimensions in the TWiki PatternSkin).
  • The "Advanced Search" page now supports a query-based search.
  • A new section type, "expandvariables", adds better control over macro expansion in topic templates. You can now create template topics with sections where all macros contained within the sections are expanded.
  • A "Copy topic" feature is now present in the "More topic actions" tools.
  • IF conditions has been expanded with an "isempty" test condition.
  • viewfile script can be used as a webserver ErrorDocument enabling both more secure attachments and user focused error dialogs.

Security Updates

Foswiki is much more secure than TWiki 4.2.4.

  • Foswiki 1.0.0 has secured by default the powerful but also vulnerable URLPARAM macro against cross site scripting (XSS) attacks. URLPARAM now by default encodes a short list of unsafe characters '"<>% which eliminates most XSS possibilities encountered with URLPARAM. This protects all topics using the URLPARAM macro without requiring any changes to them.
  • Functions QUERYPARAMS, ORIGURL (skin macro) are secured against XSS attacks. QUERYPARAMS, like URLPARAM, is now encoded with the new, safe encoding.
  • The print preview link is no longer vulnerable to XSS attacks.
  • Additional security fixes have been made, based on security audits performed by the Foswiki team. Sensitive data from the topic text and web client requests are validated for safety.

Terminology changes in Foswiki

As part of the first Foswiki product release, various topics and terms were changed to avoid using the TWiki brand name and to more accurately reflect their purpose, including the following:

  • The TWiki web is now called System, as it contains configuration information for the entire Foswiki installation. The TWikiCompatibilityPlugin provides backwards compatible support for references to the TWiki web, in order to facilitate migrations from TWiki to Foswiki.
  • The %TWIKIWEB% and %MAINWEB% variables are now called %SYSTEMWEB% and %USERSWEB%
  • Topics in the Foswiki distribution have been renamed to eliminate the TWiki word and to make the titles more readable (for example, Plugins, Skins, and so forth).
  • All templates, CSS and Javascript names have been changed from twikiXxxxx to foswikiXxxxx
  • Key terminology changes:
TWiki term Foswiki term
TWiki variable Macro
preference(s) variable preference setting, or macro when referring to expansion of same
TWiki form Data form
TWiki Plugin Plugin
TWiki Template Skin Template
Topic Template Template Topic
TWiki Markup Language (TML) Topic Markup Language (TML)
TWiki Application Wiki Application

TWiki Release 4.1 (Edinburgh), 16 Jan 2007

New Features and Enhancements of TWiki Release 4.1

  • Easier Installation and Upgrade
    • Plugins can now be installed from the configure script.
    • The loading of plugin preferences settings has been moved earlier in the preferences evaluation order so that plugin settings can be redefined in Main.SitePreferences, WebPreferences and in topics. To make TWiki upgrades easier, it is recommended to set the plugin settings in Main.SitePreferences, and not to customize the settings in the plugin topic. For example, to change the TEMPLATES setting of the CommentPlugin, create a new COMMENTPLUGIN_TEMPLATES setting in Main.SitePreferences.
    • Plugin settings can now be defined in configure instead of in the plugin topic (requires that the individual plugin has implemented this). TWiki performs slightly better by not looking for preferences settings in plugin topics.
    • Configure no longer shows many unnecessary errors when run first time.
    • The webmaster email address is now defined in configure instead of TWikiPreferences.
    • Default file access rights in the distribution package have been changed to be more universally defined and in line with the default access rights for new topics.

  • Usability Enhancements
    • Redesigned result page when typing incomplete topic name into the Jump box, so that it is possible to quickly navigate to a topic, also in a very large TWiki installation. For example, "I know there is a topic about Ajax somewhere in the Eng web. OK, let my type Eng.ajax into the Jump box... Here we go, the third link is the AjaxCookbook I was looking for."
    • Many user documentation improvements.
    • URL parameters maintained in Table of Contents links so you can stay in a temporary skin (e.g. print) and keep URLPARAM values when you click the TOC links
    • Attachment tables now sorted alphabetically.
    • Better printing of tables and verbatim text in PatternSkin.

  • Application Platform Enhancements
    • Auto-incremented topic name on save with AUTOINC<n> in topic name; used by TWiki applications to create topic based database records.
    • The edit and save scripts support a redirectto parameter to redirect to a topic or a URL; for security, redirect to URL needs to be enabled with a {AllowRedirectUrl} configure flag.
    • CommentPlugin supports the redirectto parameter to redirect to a URL or link to TWiki topic after submitting comment.
    • The topic URL parameter also respects the {AllowRedirectUrl} configure flag so redirects to URLs can be disabled which could be abused for phishing attacks.
    • The view script supports a section URL parameter to view just a named section within a topic. Useful for simple AJAX type applications.
    • New plugin handler for content move.
    • Enhancements for Ajax based applications with Foswiki:Extensions/YahooUserInterfaceContrib and Foswiki:Extensions.TWikiAjaxContrib (available at twiki.org).

    • FormattedSearch header supporting $nop, $quot, $percnt, $dollar.

    • Support for templates to have text rendering affecting aspect outside of textarea.
    • Pattern skin dependence on TwistyPlugin instead of TwistyContrib (performance improvement.)
    • Don't strip newlines from the front of TMPL:DEFs.

  • Miscellaneous Feature Enhancements
    • Change in WikiWord definition: Numbers are treated as lower case letters, e.g. Y2K is now a WikiWord.
    • Configurable template load path. Advanced feature for those that work with customized templates.

    • EditTablePlugin: Default date format based on JSCalendarContrib instead of plugin topic.
    • InterwikiPlugin: Supports custom link formats.

If you click on a header of another table all other tables goes back to the default sort defined by initsort or not sorted if no initsort, and the new table is sorted based on the user clicking on a table header.

Appendix B: Encode URLs With UTF8

Use internationalised characters within WikiWords and attachment names

Current Status

To simplify use of internationalised characters within WikiWords and attachment names, Foswiki supports UTF-8 URLs, converting on-the-fly to virtually any character set, including ISO-8859-*, KOI8-R, EUC-JP, and so on.

Support for UTF-8 URL encoding avoids having to configure the browser to turn off this encoding in URLs (the default in Internet Explorer, Opera Browser and some Mozilla Browser URLs) and enables support of browsers where only this mode is supported (e.g. Opera Browser for Symbian smartphones). A non-UTF-8 site character set (e.g. ISO-8859-*) is still used within Foswiki, and in fact pages are stored and viewed entirely in the site character set - the browser dynamically converts URLs from the site character set into UTF-8, and Foswiki converts them back again.

System requirements are updated as follows:

  • ASCII or ISO-8859-1-only sites do not require any additional CPAN modules to be installed.
  • Perl 5.8 sites using any character set do not require additional modules, since CPAN:Encode is installed as part of Perl.
  • This feature still works on Perl 5.005_03 as per SystemRequirements, or Perl 5.6, as long as CPAN:Unicode::MapUTF8 is installed.

The following 'non-ASCII-safe' character encodings are now excluded from use as the site character set, since they interfere with Foswiki markup: ISO-2022-*, HZ-*, Shift-JIS, MS-Kanji, GB2312, GBK, GB18030, Johab and UHC. However, many multi-byte character sets work fine, e.g. EUC-JP, EUC-KR, EUC-TW, and EUC-CN. In addition, UTF-8 can already be used, with some limitations, for East Asian languages where EUC character encodings are not acceptable.

It's now possible to override the site character set defined in the {SiteLocale} setting in configure - this enables you to have a slightly different spelling of the character set in the server locale (e.g. 'eucjp') and the HTTP header sent to the browser (e.g. 'euc-jp').

Details of Implementation

URLs are not allowed to contain non-ASCII (8th bit set) characters: http://www.w3.org/TR/html4/appendix/notes.html#non-ascii-chars

UTF-8 URL translation to virtually any character set is supported, but full UTF-8 support (e.g. pages in UTF-8) is not supported yet.

The code automatically detects whether a URL is UTF-8 or not, taking care to avoid over-long and illegal UTF-8 encodings that could introduce security issues (tested against a comprehensive UTF-8 test file, which IE 5.5 fails quite dangerously, and Opera Browser passes). Any non-ASCII URLs that are not valid UTF-8 are then assumed to be directly URL-encoded as a single-byte or multi-byte character set (as now), e.g. EUC-JP.

The main point is that you can use Foswiki with international characters in WikiWords without changing your browser setup from the default, and you can also still use Foswiki using non-UTF-8 URLs. This works on any Perl version from 5.005_03 onwards. You can have different users using different URL formats transparently on the same server.

UTF-8 URLs are automatically converted to the current {Site}{Charset}, using modules such as CPAN:Encode if needed.

Foswiki generates the whole page in the site charset, e.g. ISO-8859-1 or EUC-JP, but the browser dynamically UTF-8 encodes the attachment's URL when it's used. Since Apache serves attachment downloads without Foswiki being involved, Foswiki's code can't do its UTF-8 decoding trick, so Foswiki URL-encodes such URLs in ISO-8859-1 or whatever when generating the page, to bypass this URL encoding, ensuring that the URLs and filenames seen by Apache remain in the site charset.

Appendix C: CSS

Listing of CSS class names emitted from Foswiki core code and standard extensions.

Who should read this document?

Skin builders and others who want to change the appearance of the default installation or any of the skins can use this document to see what styles can be created for these html elements.

Naming conventions

  1. All Foswiki class names have the prefix foswiki - for example: foswikiAlert, foswikiToc. This makes it less likely that our CSS classes will get in conflict with other Style Sheets. Remember that CSS class names are case sensitive - Foswiki CSS uses lowercase foswiki.
  2. If you define your own CSS classes, it is preferable that you do not use the foswiki prefix to prevent undesired overriding effects.

A wide range of standard styles are used in the Foswiki core code and topics, and more are used in extensions. The following is an exhaustive list of all styles defined by Foswiki. For the most part, the names are the only documentation of the purpose of the style. For more information on how these styles are used, read the code (sorry!)
