What is the "is-title" property and when would a system have it? > I modified the 'relevant-dump-systems' function to keep all systems and it worked as I hoped. Here are some conclusions: 1. relevant-dump-systems filters through all systems and only returns those that have an 'is-title' property which is marked as 'true'. 2. The first system is the only one which has the 'is-title' property and it is always set to 'true'. This is done in 'lily/paper-book.cc'. Would anyone object to a patch where I add a '-dpreview-include-all-systems' option to lilypond? This would be used in the 'relevant-dump-systems' call in the same way that the '-dinclude-book-title-preview' is used in the 'relevant-book-systems' function to control title display. I would also add comments and make some clarity motivated function renames in this patch. -- David Sankel _______________________________________________ lilypond-devel mailing list lilypond-devel@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-devel
