jsMath

jsMath itself is working, see:

Here are some math equations. Some inline math: \sqrt{1-x^2} or \(ax^2+bx+c\), and some displayed math:

\int {1\over x}\,dx = \ln(x)+C

and

[\sum_{i=1}^n i = {n(n+1)\over 2}.]

Note that some markers do not work, and some do. You can see the original text and copy what works by looking at this page with More Actions / Raw Text in the moinmoin control panel.

Installation notes:

jsMath (javascript Math) uses TeX markup and delivers fonts and positioning via javascript. This means that no client-side fonts or interpretation is needed, such as with MathML. See http://www.math.union.edu/~dpvc/jsMath/ .

jsMath is wrapped in jsMathParser by Thomas Themel, which is a moinmoin plugin installed in the plugin directory ...wikipath.../moin/data/plugin/parser/ . This file contains a pointer to a sorta-unique instance of jsMath .

Javascript is finicky for security reasons, and will only run .js files from the same URL as the page was launched from. www.launchloop.com and launchloop.com are considered two different URLs, so you can't use ServerAlias in your apache /etc/httpd/conf/httpd.conf file; instead, you must use redirects (in this case, www.launchloop.com/ and moin.launchloop.com/ both have their own short <Virtual> blocks which redirect to the launchloop.com/ <Virtual> block. Before pages are rendered, they are redirected to this one common name.

The security restriction also means that each wiki or URL needs its own version of jsMath. jsMath contains a configuration file .../easy/load.js (which I put in ...wikipath/jsmathdir/easy/load.js) that has a reference to the URL of the jsMath root directory. In this case:

root: "http://server-sky.com/jsmathdir/",

That gets its own redirect clause in httpd.conf, so that the apache server can find the jsmath files. A complete copy of the entire jsMath (including the font files) are stored in ...wikipath.../jsmathdir/ . All very complicated and redundant. The server storage can be reduced by creating symbolic links from all the directories and files in jsmathdir to the common /opt/jsMath, except for ...wikipath.../jsmathdir/easy/load.js , which must be unique per wiki instance . This facilitates upgrading jsMath.
