See, this is where my large programming and LilyPond experience gives me an advantage over you. Instead of coming to the conclusion "I must be stupid" I come to the conclusion "this is stupid". You can get the whole file as a single string with ly:gulp-file. Or you can nest with-output-to-string and with-input-from-file (or what it was called) in a loop, read stuff in and write it out when the current input line/file number is in the indicated range. Which sounds somewhat suboptimal, particularly considering that you'll be redoing this for every file. I think I'll try cooking up some sort of Scheme function for extracting the text corresponding to a location pair and put it into LilyPond proper. That will not help you now, but it might come in handy in future. -- David Kastrup _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
