Revision Link Plugin
Compatible with DokuWiki
2009-01-25+
The missing download url means that this extension cannot be installed via the Extension Manager. Please see Publishing a Plugin on dokuwiki.org. Recommended are public repository hosts like GitHub, GitLab or Bitbucket.
This extension has not been updated in over 2 years. It may no longer be maintained or supported and may have compatibility issues.
Syntax
Just append '@<revision #>' to the page name of an internal link, e.g.
[[page@1234567890|Page (old version)]]
Installation
Just copy the code below into the file lib/plugins/revlink/syntax.php
For more help, refer to Plugins on how to install plugins manually.
Wish list
- Append to tooltip the revision a link is linking to.
- Be more permissive with the revision number, perhaps linking to the last revision at or before the given revision number.
- Allow other formats for referring to a revision, such as date and time
Issues
- Possibly would not work with other XHTML renderer plugins, as revlink assumes the existence of a particular set of arguments on the renderer's
internallink
method.
