Re: [Wikitech-l] MediaWiki hook questions

I want to preprocess the wikitext of articles adding info found by a database lookup based on the article name. The best place for preprocessing is in the parser so I've hooked ParserBeforeStrip but the parser works in chunks of wikitext rather than in articles. I've been able to filter out the chunks which are not part of the article because $parser->getVariableValue('revisionid') will return 0 for those. But long artices can cause more than one chunk of wikitext to be sent to the parser and since I only want to add to the top of the article I need to detect these chunks and ignore them. Another problem is that I also want to add to the top of the 'noarticletext' page which is displayed when the user enters a URL for a page which doesn't exist. There is currently no hook for this. I've tried adding one which works for me but there are actually 3 places in the code which can result in this page. I'm not sure that I need to hook the other two since they appear to be edge cases. One final question is on sharing data between my hooks for ArticleAfterFetchContent and ParserBeforeStrip. I'm using a global variable but maybe there's a better way. ArticleAfterFetchContent seems to be the best place for doing the database lookup based on the article name to work nice with the cache. Andrew Dunbar (hippietrail)
