Warning: this piggybacks on 'alt' text and can be broken if a manual alt text was specified on a <math> bit. Needs to be more nativey.
Also cleaned up the conditional setup code since we're already only called when a <math> is present.
* Tested AbuseFilter.
* Did not test ArticleCreationWorkflow, Configure, ContributionTracking, FlaggedRevs, FundraiserPortal, InlineCategorizer, MarkAsHelpful, Math/Mathjax.
* Fixed a typo in a comment in LiveTranslate.
* Did not review extensions alphabetically after MoodBar.
* Pulled in MathJax 1.1 (minus the 112 megabytes of PNG "fonts")
* Pulled in some of <https://en.wikipedia.org/wiki/User:Nageh/mathJax> bits for initialization
This doesn't currently override PNG images, but does replace the text-form if you configure it.
PHP Parse error: syntax error, unexpected T_STRING, expecting ')' in /home/betawiki/projects/mediawiki-ext/Math/Math.i18n.php on line 2235
Full export will readd missing messages.
If enabled, by default loads MathJax from a CDN and forces all equations through MathJax when JavaScript is available -- the image or source form gets used only as <noscript> fallback.
This has a couple of problems for us:
* if scripts are missing -- such as when viewed via MobileFrontend -- you end up with no math at all, as the <script type="math/tex"> bits get ignored but the <noscript> still hides the images.
* while MathJax is loading things, blank spots on the page may appear and stuff jumps around
* if loading new text in via ajax, it doesn't trigger there
Also using some fairly default config, no idea how appropriate it is. Hoping to get some insight from Nageh who's done some of the MathJax work on Wikipedia so far - <https://en.wikipedia.org/wiki/User_talk:Nageh#MathJax_integration_into_stock_MediaWiki>
MathML mode was so incomplete most people thought it simply didn't work (bug 25646).
HTML modes often rendered poorly (eg req bug 24207 to set default to PNG on some sites)
This may cause regressions in that simple "equations" of just variables that came out as HTML
will now render as PNGs that don't get aligned properly with the text baseline. Fixing this is
covered by bug 32694: <https://bugzilla.wikimedia.org/show_bug.cgi?id=32694> to retrieve the
baseline info from dvipng and position images to fit.
Note that because of the way user options are pulled in to the oarser cache key, some folks
may see cached pages with their old settings until they get redone or they save their prefs
again and have it normalized.
