ℹ THIS REPO IS FORKED FROM cben/mathdown. I just did the redesign.
⚠ Alpha quality! Will eat your math, burn your bookmarks & expose your secrets.
🐛 Known bugs are listed here.

- CodeMirror, as the basis for wysiwyg editing in
contentEditable; - MathJax, for magical typesetting of LaTeX equations;
- glued by CodeMirror-MathJax;
- Firebase’s Firepad, for real-time collaboration.
- Free testing courtesy of Sause Labs.
- @cben’s code (including CodeMirror-MathJax) is under MIT License.
- My css too.
- CodeMirror is also MIT.
- Firebase is a proprietary service (#4); their client-side javascript API firebase.js is MIT.
- The collaborative editor Firepad is MIT. It calls firebase javascript API.
After checking out, run this to materialize subdirs://
git submodule update --init --recursive
Append --remote to upgrade to newest versions of all submodules (need to commit afterwards if anything changed).
@cben is directly working in the gh-pages branch without a master branch, as that’s the simplest thing that could possibly work (http://oli.jp/2011/github-pages-workflow lists several alternatives).
The redesign was inspired by this discussion, and as an experiment in search for how wysiwyg Markdown editing could look like.
