initial patch
As far as I know there is no way to modify revision texts passed to the
difference engine. This hook, attached to the entry, provides a simple solution
to the problem. It implements RevisionsBeforeDiff hook that can be used as
follows:
...
$wgHooks['RevisionsBeforeDiff'][] = 'combineNewRevisionWithRequest';
function combineNewRevisionWithRequest( &$oldRevText, &$newRevText ) {
if( pageIsEditable() ) {
global $wgTitle;
$editPage = getEditPage($wgTitle);
$newRevText = renderProperties($editPage) . $newRevText;
removeCommentLines($oldRevText);
removeCommentLines($newRevText);
}
return true;
}
...
Even though the code is out of context I hope it manages to convey the idea and
the need for this particular feature.
