[IPython-dev] how to implement syntax highlighting for a new language

[Matthias Bussonnier]

Hi Robert,

Once your highlighting mode in in the right place in the codemirror
directory (notebook/components/codemirror/mode/modename/modefile.js
IIRC) you need your kernel-info-reply to give the name of the
codemirror mode is one of the field. Most of the time the language
name is enough, codemirror has a mapping Language<->mode.

Otherwise you can explicitely set the mode.
See http://jupyter-client.readthedocs.org/en/latest/messaging.html#kernel-info

If you can point us to where your mode is, and where your kernel is we
can help you to figure that out.
