Not needed anymore

While this plugin may have been necessary with older releases of Dokuwiki, it is actually not needed anymore, unless you want to use the specific @ syntax.

To create a link to a page's specific revision, you can simply use a regular internal link, appending ?rev=XXX to the page name, e.g. Old revision of this page :

[[revlink?rev=1238874513|Old revision of this page]]

This has been tested with Release 2018-04-22 “Greebo”.


Just append '@<revision #>' to the page name of an internal link, e.g.

[[page@1234567890|Page (old version)]]


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


  • 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.

It seems that revlink is not compatible with siteexport 2016-08-30. Deactivate the siteexport plugin to work with revlink.

It seems that revlink is not compatible with the move plugin. Deactivate the revlink plugin to work with move.
