Thanks to everyone who wrote the script. I've been using it for my
website.

I actually modified the posted version to suit my own tastes, so I
wanted to share these suggestions, and if you like some of them, they
could be incorporated into the main code (my modifications are very
hacky, because I don't really know javascript at all).

My modifications are here:
http://www.acm.caltech.edu/~srbecker/textheworld7.user.js
http://www.acm.caltech.edu/~srbecker/textheworld7.user.block.js

The main suggestions:

(1) for inline expressions, the latex image was always vertically
centered rather funny. I was able to easily fix this by adding this
line:
imgElement.style.verticalAlign = "middle";
to
function createTeXifiedImageElement(expr)

(2) my webpages are generally static, so I don't need any fancy
refreshes. But I also don't want to wait 3 seconds for the images to
render - I want that immediately! So it would be nice to give this as
a second option. My current hack around this was to replace
setInterval(TeXTheWorld, 3000);
with
setTimeout(TeXTheWorld, 0);

(3) the second file, the "block" file, is like the first, but it looks
for [[; and ;]] instead of [; and ];, and it displays the equations as
"block" style as opposed to "inline" style, i.e.
imgElement.style.display = "block";
The intention is that it functions like ...
in latex.
I made this in a second duplicate script (and renamed the functions),
but of course this is wasteful and I only did it because it was quick
and I don't know javascript well.

An example of how I used everything is here: http://www.acm.caltech.edu/~srbecker/inverse.shtml

Some of these you may not agree with but just wanted to put them out
as suggestions. Thanks for the great code.

Hi Stephen,

Thanks for doing these modifications. Unfortunately I don't have enough free time anymore to maintain this and I could hardly get to some of the other suggestions people made. Would anyone want to take over maintaining this?

Thanks,
Avital.
