Contributors Plugin

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 (Web Contributors) that allows the user to access the contributor history via a regular URL.

The Web Contributors 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 arguments to %CONTRIBUTORS% are also allowed:

argument	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 home 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 Web Contributors, 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 Web Contributors for that topic.
Instead of using rev, you must use revision. If you use rev, then bin/view will expand that revision of Web Contributors instead of expanding the current version of Web Contributors.
