The context modifying stream events are _completely_ different from their originating music expressions. Most stream events are converted directly from music expressions in the manner you do it here. However, the stream events for modifying context properties are generated by separate iterators and are basically ad-hoc (this seems weirder these days than it may have been in the grey mists of time since in olden times it was the responsibility of the iterator to implement "\\once", something that it could not actually reliably do). Check the source code in lily/property-iterator.cc to see what to generate here for the various events (Push/Pop correspond to override/revert). -- David Kastrup _______________________________________________ lilypond-devel mailing list lilypond-devel@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-devel
