That's where the Custos_engraver sees graphical objects that have been declared to have a note-head-interface pass into the current score. > My problem is that, while I'm willing to learn, I have a very limited > experience with C++ and with any object programming whatsoever (having > spent much time decades ago with Turbo Pascal 5 :-)). Well, imagine how frustrating it would be if you were a gee-whiz C++ programmer and still couldn't tell the stuff LilyPond does from Turbo Pascal 5. C++ knowledge actually does not buy you all that much for reading the source code. > I'd be very grateful for any pointers regarding what happens during a > linebreak (and, in general, how one should learn such things). I'd take a look at the Contributor's Guide first: there are a few sketches of code workings in it. There is a file ROADMAP in the repository that points out what kind of code is grouped into which directories. Other than that, it's mostly reading code and asking back on the list. -- David Kastrup _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
