Up to now, \once \revert is not really documented nor used. I have not yet dug through the existing code in order to figure out what it does if anything (most likely ignoring \once, but not sure).
In order to not have the override/revert stack get into unexpected interactions, I want to change \once\override to be impervious to normal reverts. That would mean that \once\revert is an obvious candidate for reverting a \once\override before its time. However, I have no idea whether there is an actual sensible use for that functionality. \once\revert could also mean to let a current non-once override become inactive just for the current time step. That's likely harder to implement, I think. Again, I have no idea whether there is an actual sensible use for that either, and it looks rather ad-hoc. IF one wanted to get crazy, one could use \once\revert for one of the two things, and \revert\once for the other. Which one for which, and would anybody remember that? Since the parser permits \once\revert, I tend towards making it match the last \once\override. It likely does not make much sense, but then it is sort of easy to understand. -- David Kastrup _______________________________________________ lilypond-devel mailing list lilypond-devel@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-devel
