Before picking the particular algorithm: I have had my trouble following the previous discussion. To summarize what I glean from the code: script_priority: input property for the function. The output lists shall have non-descending(?) values of script_priority. This is achieved by a stable sort at the start. outside_staff_priority: optional input property, required output property. Has no influence on the order of output. Resulting outside_staff_priority shall be non-descending. Previously specified values of outside_staff_priority are taken into account. Note that if outside_staff_priority has no influence on the sort order, and we want to get a non-descending sequence of outside_staff_priority, this implies that most preexisting values of outside_staff_priority have to be trashed. Unless I don't understand something. Well, I certainly don't, but that does not mean that it is relevant. -- David Kastrup _______________________________________________ lilypond-devel mailing list lilypond-devel@gnu.org http://lists.gnu.org/mailman/listinfo/lilypond-devel
