The math sites have a nice Pagedown + MathJax integration.

It seems mostly based on this Apache 2-licensed code by MathJax developer David Cervone with some minor updates to work around an IE bug and issues with backticks.

Several people would like to do the same style of integration on their own sites.

Thus, my questions:

  1. Can someone on the Stack Exchange team publish/open-source the latest non-minified mathjax-editing.en.js file?
  2. If nobody is willing to do #1, can I unminify the latest minified mathjax-editing.en.js and publish it (e.g. as a Gist)? This is similar to what StackOverflow did with the WMD editor.

    It is unminified here but I don't know the answer to the license so I'm not sure if you can use that.

    To be 100% safe I'd recommend NOT doing #2 and patiently wait for #1 to happen. Publishing somebody else's code based on assumptions that it probably is also Apache 2.0 is a very risky feat.

  • The unminified version at dev.sstatic.net/Js/mathjax-editing.en.js now shows an MIT License at the top.

We have published a GIST for the Pagedown + MathJax integration under the MIT license.


Feel free to do with it what you will!
