History Plugin

This plugin shows a complete or partial history of a document. The output can arbitrarily be formatted. An example for a Wikipedia-like history is included.

When using PatternSkin enabling the HistoryPlugin changes the "History" link in the bottom action bar so it opens a page with a nice user interface where you can select the versions to compare.

With other skins for Foswiki you will need to tweak the templates.

If CompareRevisionsAddOn is installed and activated the "History" user interface will allow you to choose how the changes are rendered (interweaved vs side-by-side, and context).

If RevCommentPlugin is installed and activated the "History" page will show the comments entered for each revision.

This plugins is designed to work together with CompareRevisionsAddOn and RevCommentPlugin but works well on its own or with just one of the two other plugins.

Syntax Rules

  • %HISTORY{parameters}
    Supported parameters:
    Parameter Description Default
    "format" or format="format" Format of one line, may include any variable which is supported by %REVINFO% "r$rev - $date - $wikiusername"
    topic="topic" Topic name Current topic
    web="web" Web name Current web
    nrev="nrev" Number of revisions to show. Ignored, if both rev1 and rev2 are specified Plugin preference variable NREV
    rev2="rev2" Newest revision to show rev1+nrev, if rev1 is specified, latest revision otherwise
    rev1="rev1" Oldest revision to show rev2-nrev
    reverse="on/off" Show newest revisions first, if on "on"
    header="text" Text to print before the list. May contain the variables $next and $previous (see below) "$next"
    footer="text" Text to print after the list. May contain the variables $next and $previous (see below) "$previous"

The parameters header and footer may contain the variables $next and $previous, which will only be evaluated, if there are newer or older revisions available for the topic which are not listed according to rev1, rev2, nrev. These variables take the syntax $next{'text' url='url'} (analog for $previous). text is the text which should be printed, url is the url for a corresponding link. The variables $rev1, $rev2, $nrev in text or url will be replaced by appropriate values for the next or previous block of revisions. See the attached oopshistory.tmpl for an example of how to use this.

The following variables are replaced only, if there is a corresponding %HISTORY% on the page. If more than one %HISTORY% is used on the same page, the values from the last one will be used.

  • %HISTORY_REV1%: Oldest revision from the printed history
  • %HISTORY_REV2%: Latest revision from the printed history
  • %HISTORY_NREV%: Number of the printed revisions
  • %HISTORY_MAXREV%: Latest available revision of the document


The call %HISTORY% shows a simple list of available revisions like

r3 - 17 Feb 2005 - 09:56 - AnUser
r2 - 31 Dec 2004 - 10:22 - AnotherUser
r1 - 15 Nov 2003 - 01:23 - YetAnotherUser

For a more complex example see the attached oopshistory.tmpl which also allows the comparison of two selected revisions.
