==How A Page is Built==
''(From [[User:Woozle|Woozle]] 21:59, 15 Jun 2005 (EDT).)''
*Everything obviously starts with [[MediaWikiDoc:index.php|index.php]]
*For the purpose of displaying a page (not saving changes or doing anything else), this calls $wgArticle->view(), in [[MediaWikiDoc:Article.php|Article.php]] (line 699)
*$wgArticle->view() appears to be able to provide a few other formats besides the regular view (including difference engine and displaying redirections as subtitles), but I'm ignoring that for now
*$wgOut seems to be the object which accumulates text to be output, via various methods:
**$wgOut->addWikiText(...)
**$wgOut->addHTML(...)
**$wgOut->addPrimaryWikiText() # Display content and save to parser cache
**$wgOut->addWikiText() # Display content, don't attempt to save to parser cache
**$wgOut->setPageTitle()
**$wgOut->transformBuffer(); # Put link titles into the link cache
**$wgOut->addMetaTags(); # Add link titles as META keywords
*...and then it does these two lines:
**$this->viewUpdates(); ''(found at line 1926 -- doesn't do much)''
**wfProfileOut( $fname );
*It's not clear whether the navbar has already been pulled in by the time we hit viewUpdates -- possibly transformBuffer does it? The comment makes it sound like that, but the name "transformBuffer" in that case is not very descriptive. The code in there should probably be examined.
