Hi all, I want to share a new feature I just pushed for lilypond-ts-mode: cycle forward/backward through the same rhythmic position in all parts, even if they are spread across multiple files. This is made possible by evaluating LilyPond code within a Guile REPL using an engraver that outputs a list mapping moments to input locations.
I'm pretty excited about this, as it's a type of editing workflow that has been much requested over the years, and which as far as I know has not existed before. I believe that the Scheme part of this could probably be upstreamed into LilyPond and used by non-Emacs editors to implement a similar feature. Fair warning, there are probably some bugs at this stage, hence why I haven't yet shared this on the user list. But please give it a try: https://github.com/shevvek/lilypond-ts-mode. Saul
