This conversation is throwing much light on the difficulty that even the computer literate face when trying to learn the Lilypond Scheme interface.
In this case the simple addition of a mark is seen to be very complex with procedures and arguments that are counter intuitive (or at least nowhere near intuitive). Nor are they and their uses fully defined in the manuals (I'm sure it is obvious to a developer but confusing to an outsider). Secondly there are apparently several ways to skin the cat and contexts that are not immediately obvious. Guidance at the gateway would be a very productive way to spread the use of Lilypond beyond highly qualified developers into the more mundane world of the everyday user. None of this is criticism of the project which is a remarkable achievment - more a cry from the wilderness for a helping hand to newcomers. Actually not so much a helping hand more an appreciation of the misconceptions and misunderstandings that plague the tyro. _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
