Althought it's still source code, I'd advise looking at Neatroff sources: it is, as far as I can judge, clean, small, and easier to understand than the other troff sources I looked at. It also contains features that worth being considered today: paragraph at once adjustment and right to left scriptures. Here it is: https://github.com/aligrudi/neatroff Kind regards, Pierre-Jean.
