We're reviewing source code in a language that is not currently supported by Collaborator (Ada). It would be useful to be able to add a language syntax highlighting definition. There are other tools, e.g. Ultraedit, that do this with a simple text file that lists keywords against formatting options (colour, bold etc). The filename extensions are then mapped to the language definition.

https://highlightjs.org/ offers HTML support via JS for 135 languages and 65 styles. See https://github.com/isagalaev/highlight.js/tree/master/src/languages for complete list.
See https://highlightjs.org/usage/ for usage and how to integrate into app. For collaborator, this looks like it would integrate very well into your technology. Supports language extensions as well.
They just implemented this in Collaborator 11.0.11000
