945228 - Add basic math editing features

Status: RESOLVED FIXED

(developer.mozilla.org Graveyard :: Editing, defect)

Description

[Frédéric Wang (:fredw)]

Just opening that bug for the record and if some volunteers want to help...

The basic idea will would be to integrate a small TeX/ASCII-to-MathML converter like http://www1.chapman.edu/~jipsen/mathml/asciimath.html to generate MathML client side when editing a page.

More advanced editing features could be helpful like improving the WYSIWYG editor. This is the huge task of the old bug 78128 ; some UI could be added to MDN to insert basic constructions. It would also be possible to allow a simple syntax in the source and doing the MathML conversion server side, but that would be a bit more involved and so should be addressed in a separate bug.

There is a plugin for CKEditor4 to cover this in https://github.com/r-gaia-cs/CKEditor-TeXZilla (demo at http://www.ime.unicamp.br/~ra092767/ck-texzilla). I still have to test it with Kuma and maybe backport it to the CKEditor version that Kuma use.

The plugin make use of Frédéric's parse: https://github.com/fred-wang/TeXZilla.

Some quick remarks:

- the rendering in the preview seems quite different to the actual rendering (e.g. variables are not italic). I saw somewhere that you have a list of allowed markup so perhaps it is the reason (for example we use _moz attributes in the Gecko release). It is possible that this is some Gecko bugs with Javascript.

- At the moment, I'm not sure an advanced panel is really needed, so perhaps the RTL checkbox could be moved to the main panel...

- when I update the RTL/Display checkbox, this does not seem to be taken into account in the preview (although it is is in the final rendering). The RTL is updated in the preview if I reedit the equation again.

- I updated TeXZilla today so you might want to use the latest version (I'm still not entirely happy with it for a release, though).
