Hi, For our department Wiki, I really needed automatic links for acronyms because we have a whole bunch for them. So, after couple of days playing with code and regular expressions I managed to create Radeox filter, which converts acronyms to links. My questions are: 1) Is that the right approach to do that or I should write plug-in? Can you write a plug-in that processes every page, or you have to call it explicitly? 2) What is the right place to attach it to rendering? I attached it to the end, just before link filter, but then I had to struggle with HTML. It will be probably easier to write something that processes pure Wiki or abstract syntax tree, but it seems to me that there is no such place in Wiki. If I do the processing immediately after page is loaded, macros are not evaluated yet, therefore text generated by macros can't be processed (I don't know is this a big deal, though). It seems to me that macros are generating HTML instead of Wiki, which is not very clean. On the other hand it will be hard to write event simple macros with formatted text (e.g. "warning") without generating HTML directly, or introducing some kind of style tags for Wiki markup. 3) Radeox status: What is your experienece with Radeox team? Is there anybody still working on the project? I found some some funny stuff in the source code, which I would like to fix. They "swallowed" exceptions in some places, so if you mis-configure filter, you will not why it doesn't work.
