Hello everyone! Over the last four months, I've been working on a TextMate-compatible grammar <https://github.com/Alhadis/language-roff> to improve the highlighting of Roff source on GitHub. I submitted my pull request <https://github.com/github/linguist/pull/3126> earlier today, and the effect on code readability is *very* visible. Examples are in the PR.
The grammar's highlighting can be tested using GitHub's Lightshow <https://github-lightshow.herokuapp.com/?utf8=%E2%9C%93&scope=from-url&grammar_url=https%3A%2F%2Fgithub.com%2FAlhadis%2Flanguage-roff%2Fblob%2Fstatic%2Froff.json&grammar_text=&code_source=from-url&code_url=https%3A%2F%2Fgithub.com%2Frust-lang%2Frust%2Fblob%2Fmaster%2Fman%2Frustdoc.1&code=>. It'd be great to hear some feedback from veterans on the highlighting accuracy! Cheers, - John
