It would actually be quite simple to implement: In scm/lily-library.scm in the print- book-with function, instead of storing the file count as a number in 'output-count, store it in an alist (which is set as the 'output-count parser variable), with the suffix as key. This way, the counting is per suffix and we'll automatically not append the number for the first file with a given suffix... I think this would be quite a nice task or a frog, so I'm not coding it myself, just giving a few pointers... The way to work with the alist (that's Scheme's idea of a Hash) can be seen e.g. in my counter snippet on LSR: http://lsr.dsi.unimi.it/LSR/Item?id=543 All you need to do is to use assoc-ref instead of count and ly:parser-define! (instead of the set! in the counter example) with assoc-set! to set one entry of the hash / alist. The key for the alist would be the suffix. The rest of the function doesn't even need to be changed... Cheers, Reinhold PS: Why do we call (string-regexp-substitute "[^a-zA-Z0-9-]" "_" output- suffix) on the suffix? This makes it impossible to use e.g. "Flöte" as the suffix, which is German for Flute! Similar, any other accented or non-latin letter is not possible and will be replaced by a "_". Similarly, spaces or + etc. are also not allowed... I understand that some letters may cause problems (in particular, ":", "/", "\" and maybe also "?" and "*"), but I don't think this is a reason to prevent everything other than latin letters and numbers. - -- - ------------------------------------------------------------------ Reinhold Kainhofer, reinh...@kainhofer.com, http://reinhold.kainhofer.com/ * Financial & Actuarial Math., Vienna Univ. of Technology, Austria * http://www.fam.tuwien.ac.at/, DVR: 0005886 * LilyPond, Music typesetting, http://www.lilypond.org -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) iD8DBQFJpm+wTqjEwhXvPN0RAgD5AJ9Yevrt36GTtR544ti788eerN3+pACgjXuT oNwcsvyQzNkBe8JVjnixem0= =//Rx -----END PGP SIGNATURE----- _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org http://lists.gnu.org/mailman/listinfo/lilypond-user
