Drag this link to your bookmarks toolbar in order to commence rockin': HTTex

Rockin' entails the following: when you're editing a document in Writely, if you select a bit of LaTeX math code and hit the bookmarklet, the code will be transformed into a beautiful image of the corresponding equation. Select the image and click the bookmarklet again, and you'll get back the original text. Easy!

If you screw up the markup, you'll get a broken image, but you'll be able to see your faulty LaTeX as the alt text for the image. I'll improve that aspect of the interface in due time. Email me at newmanb at stanford dot edu if you feel like bugging me about it. I'm open about what I have left to do: here's my TODO list.

If you don't know LaTeX, you shouldn't be here, because I'm afraid I can't help you. This is nothing like a GUI equation editor. It's just a convenience for folks who like Writely and LaTeX. Note that your LaTeX snippet actually gets interpolated into an eqnarray* environment, so you can use &s to separate the left- and right-hand-sides of the equation, and even split the thing onto multiple lines with standard \\ line breaks.

Here's a small example of what you can do with just one click:

\sum_{i=1}^n i = \frac{n(n+1)}{2}
