Extension talk:HistoryOfPage

Running under mediawiki 1.16 (on Windows Server 2008), the posted code gives an error.

This has been fixed - new code below

I'm not a maintainer, but it was important to me to get this working.

This version changes the basic functionality - no longer returns links to all versions, just the history of the page prior to and including this version. Also strongly formatted the output (HTML4 transitional or previous).

I've not attempted to take over this extension or re-post the code, as the function of the extension has changed in my version. Rather than re-issue a new extension completely, I have posted this as comments for those who want it to work the way that I do.

To get this this working with the PdfBook extension, you need to add the top line to PdfBook as follows: $text   = $wgParser->preprocess($text, $title, $opt); $out    = $wgParser->parse($text, $title, $opt, true, true);

To get PdfBook working with historical revisions of documents takes some effort - head over to the extension talk to see my comments there.

I'll also convert PdfBook to work with WkHtmlToPdf rather than HtmlDoc, as the results from that program are 1) better, 2) working in latest version and 3) maintained by someone who hasn't gone out of business.
