I'm trying to get MathJax working on a TiddlyWiki (TiddlyWiki.org , a
one file wiki project). I have an TiddlyWiki plugin which uses jsMath
(Plugin:jsMath from http://bob.mcelrath.org/tiddlyjsmath-2.0.3.html)
and it seems to work fairly well. My idea was to simply load MathJax
instead of jsMath and tweek the jsMath plugin to use MathJax instead.
However, I have yet to accomplish this.
I'm sure it should be very easy but, despite being a decent
programmer, I'm very new to javascripts and web development in
general. Is anyone out there working on something similar who has
already done this or can help me?
I'm almost sure its very simple for someone with more experience/
knowledge on the subject.
Thx

Thedos,
Interestingly, I had a private inquiry about using MathJax with
TiddlyWiki last week as well. We haven't had time to look at it yet,
so if someone else out there has an idea, that would be great!
However, it's in the queue and one of us will try to find to time look
at it soon. At the moment, we are trying to focus on getting out a
new beta with MathML support enabled, so it might not be until after
that.

I use MathJax with mediawiki wiki - just substituted in jsMath plug-
in. Just in
LocalSettings.php:
$wgJsMathRoot = "http://weyl.math.toronto.edu:8888/mathjax";;
and in
extensions/JsMath/JsMath.php:
$wgOut->addScript( '<script type="' . $wgJsMimeType . '" src="'
. $wgJsMathRoot . '/MathJax.js"></script>' );
No doubt something like this should work

Bob McElrath was one of the first people to incorporate jsMath into a
Wiki setting, and TiddlyWiki did a lot to help establish jsMath in
that environment. Because Bob's plugin was an early adopter, not all
of jsMath's current features were available at the time; for example,
the easy/load.js mechanism for configuring jsMath wasn't available,
and I think maybe even the tex2math preprocessor might not have been
there (I know for sure that its processing of latex environments
outside of math mode was not implemented yet). So the plugin does
more than it would have to if he wrote it today. So it might not be
the best choice of template for MathJax.
I took a very quick look at it, and there are a number of things that
will have to be changed to work with MathJax. First, it makes very
specific use of some internals of jsMath that are not the same for
MathJax (setting the root location of jsMath, turning off the initial
processing pass, and so on). It also seems to use XmlHttpRequest as
its AJAX method, and that will not be effective for MathJax (since
MathJax relies on the fact that it is loaded with a SCRIPT tag in
order to handle its configuration).
So the section of the plugin that loads jsMath would have to be
substantially changed for MathJax. Something like
(function () {
var HEAD = document.getElementsByTagName("head")[0];
var SCRIPT = document.createElement("script");
SCRIPT.src = String(document.location).replace(/[^\/]*$/,'MathJax/
MathJax.js');
HEAD.appendChild(SCRIPT);
})();
might work to load MathJax from a MathJax subdirectory of the
directory where the tiddlywiki file is stored. That would cause
MathJax to use its MathJax/config/MathJax.js file for configuration,
where you can set what input and output jax to use, the preprocessors
to run, and so on.
It looks like Bob took some pains to prevent jsMath from doing its
initial processing pass (it seems to process the tiddlers as they
open), so you may want to turn off MathJax's initial pass by changing
the value of skipStartupTypeset in the config file.
The rest of the plugin (from "Define wikifiers for latex" on) seems to
be doing much of the same sort of thing that the tex2jax preprocessor
will do, so I'd say you can remove that and let tex2jax handle that
part. The only thing I think you need to include is the last routine,
which looks like it is there simply to call
jsMath.ProcessBeforeShowing() at the right time. You want to have it
call MathJax.Hub.Typeset() instead.
I haven't tried any of this, but that's what it looks like to me.
Give it a try and see if that gets you anywhere, and report back when
you have any news. Thanks.

Thank you very much for your prompt replies.
I still haven't gotten around to do much testing as this is something
I'm working on on the side, but I thought I'd at least send my
appreciation. To be honest, the instructions are going a bit over my
head, sorry I'm very new at this. I have a friend whom is working
with TiddlyWiki also, perhaps my friend is better able to get this
going.
I'll let you know how it goes, any further instruction/help is very
welcomed.
Thanks,
David

It did seem the obvious thing to hope that MathJax could become a
TiddlyWiki plugin as Bob McElrath had arranged for jsMath. But I
found understanding what was going on in his embedding beyond me, so
couldn't try for MathJax. We have had a version of the TiddlyWiki
form of the Math Subject Classification MSC2010 working happily with
jsMath, though the present form uses the LaTeXMathML Plugin
http://msc2010.org/MSC-2010-server.html[\url]. The plugin allows a
user to make simple notes with math in a downloaded personal copy of
the MSC from [url]http://msc2010.org/MSC-2010-personal.html[\url].
Since the AMS is going on to MathJax it will be better to be using
that for the MSC as well. This new posting gives hope that we can get
a MathJax TW plugin and I'm grateful for something more to try. It
also explains, perhaps:
MathJax does not work inside a minBrowser in TiddlyWiki.
For a view of this not working see
[url=http://www-personal.umich.edu/~pion/WebGeom/
TiddlyGeom.html#[[MathJax%20MiniBrowser]]]http://www-
personal.umich.edu/~pion/WebGeom/TiddlyGeom.html#[[MathJax
%20MiniBrowser]]
and you can also see that Soares's MathSVG Plugin does a pretty good
job of dealing with some
of the same material, if you have a MathML rendering browser like a
recenrt FireFox, by visiting
[url=http://www-personal.umich.edu/~pion/WebGeom/
TiddlyGeom.html#[[MathJax%20Preview]]]http://www-personal.umich.edu/
~pion/WebGeom/TiddlyGeom.html#[[MathJax%20Preview]]
Other heavy JavaScript pages, like another TW page, perform fine in a
miniBrowser.
Note that the rest of the material on that TiddlyGeom is pretty
scrappy and not ready for prime time.

@David:
You're welcome, and I hope we can get the plugin working eventually (I
don't use TiddlyWiki myself, and can't take time at the moment to
learn how to write plugins for it, but perhaps after MathJax v1.0 is
out I can do that).
@Patrick:
I'll check into the miniBrowser problem (Firefox's security policy is
blocking it from working, and the problem has to do with MathJax's
interaction with the IFRAME that contains the miniBrowser). I'll need
to do some experimenting.

@Patrick:
I have fixed the problem with MathJax in an IFRAME, but haven't yet
updated the copy on www.mathjax.org, so your example still won't work
until I do that. that should be sometime next week. But if you try
it from a site that has an up-to-date copy of MathJax, it should work.

Davide,
That's great. Thank you very much. TiddlyWiki's IFRAME use, such as
in miniBrowser
and External Tiddlers can be very handy sometimes.

I have been working on this and have it in an intermediate state here:
http://myweb.dal.ca/haines/#Plugin-MathJax
It works as is right now, but check the MathJax Sample tiddler - not
rendered...
But when I load it in the MarkupPostHead Tiddler as I have in the
instructions it all works fine... but I'd rather load it dynamically
as you suggest. But if I do (as currently) the two calls to
MathJax.Hub.Typeset that I have currently commented out are
undefined...
So how do I reference the dynamically loaded MathJax in this case?
I will play with skipping the other code and using tex2math once I get
past this. (as well as addressing the IE8 bug - I have tried all the
usual suggestions to no avail)
The old jsMath plugin used an ajax call to load jsmath, and I
experimented with using the TiddlyWiki embedded jQuery ajax request
directly...
But I like loading it as you suggest... just how to call it?
It will process on its own startup, but if I turn off the the initial
typeset it does not render the math (as I desire). I want to call it
on demand... I can if I put the MathJax script tag and config in the
MarkupPostHead tiddler (as in the current plugin instructions - but
not currently done), but I'd rather load it dynamically for fewer
edits for the user to install...
Hopefully you can see where I'm going here, I don't think I've
explained it very well, but I think you'll get it...
(note: not working in IE8, works in IE9 and all other browsers though
- go figure...)

I totally redid it.
I figured it out: let majthjax/tex2jax do all the work, as you
suggested, and just tuck the window.wikify redifinition inside the
appended MathJax script tag. Works in all browsers now too. (have not
added X-UA compat tag for IE tho...)
