Contributors Plugin

Show contributors of all revisions of a given topic; useful for licenses that require attribution

Overview

This plugin gives a variable (%CONTRIBUTORS%) that will show information about past edits of a topic, and allows:

  • showing only up to a give revision
  • showing only a given number of lines
  • using a custom format
  • using a custom header.

The %CONTRIBUTORS% variable can be used in templates to automatically display who has edited a page and when.

Included with the plugin is a page (WebContributors) that allows the user to access the contributor history via a regular URL.

The WebContributors page is useful when publishing information with a license that requires attribution, such as several of the Creative Commons licenses. The people who create derivative works can then put a URL that embeds the web name, topic name, and the current revision number in their attribution notices.

Syntax Rules

Using the %CONTRIBUTORS% variable alone will expand to show the author, revision, and date of each edit of the current topic. Here's what it looks like:

%CONTRIBUTORS%

The following parameters to %CONTRIBUTORS% are also allowed:

Parameter Default Description
web current web which web the topic of interest is in
topic current topic which topic to give change history for
rev current revision latest revision to show information for
format " * $author -- Revision $rev on date $date \$n"; format for each contributor line
header (none) string to print before printing the contributors output
nodups (none) if set to "on", suppress duplicate lines

In the format string, the user can use the following variables:

Variable Expands to
$author the person who made that specific change (linked to their TWiki user profile page)
$date the date in GMT time
$rev the revision number (linked to that revision of the page)
$n \n

In the header string, the user can use $n but no other variables (at the moment).

To use WebContributors, you pass a URL with the information you want in the query string. Note, however, that there are some differences:

  • Instead of using topic, you must use page. If you use topic, then bin/view will display that topic instead of displaying WebContributors for that topic.
  • Instead of using rev, you must use revision. If you use rev, then bin/view will expand that revision of WebContributors instead of expanding the current version of WebContributors.

Plugins Settings

Plugin settings are stored as preferences variables. To reference a plugin setting write %<plugin>_<setting>%, i.e. %CONTRIBUTORSPLUGIN_SHORTDESCRIPTION%

  • One line description which is shown in the TextFormattingRules topic:
    • Set SHORTDESCRIPTION = Show contributors of all revisions of a given topic; useful for licenses that require attribution

  • Debug plugin: (See output in data/debug.txt)
    • Set DEBUG = 0
