<http://lilypond.org/doc/v2.15/Documentation/usage/command_002dline-usage#command-line-options-for-lilypond> -d,--define-default=var=val This sets the internal program option var to the Scheme value val. If val is not supplied, then #t is used. To switch off an option, no- may be prefixed to var, e.g. -dno-point-and-click is the same as -dpoint-and-click='#f' But that does not seem to work fine anyway with user defined options, which come too late, even if defined in an init file included with -i. > marc@olivia:~/sandbox$ Lilypond -dno-foo foo.ly > GNU LilyPond 2.15.23 > Warnung: keine solche interne Option: no-foo > »foo.ly« wird verarbeitet > Analysieren... > foo option: #t > Success: compilation successfully completed > > so the value remains #t in both cases, and the option > "no-foo" is marked as an unknown interal option. > > What is wrong here? How embarrassing! I so wanted the second one to be false that I misread it! Actually, `ly:add-option' sets the value of the option, disregarding the command-line parameter. (Now I remember why I never use it in my own projects.) So here is a solution: use a without-slur option (instead of no-slur), and do not use `ly:add-option'. $ cat toto.ly \version "2.15.20" #(format #t "~%without-slur option: ~a" (ly:get-option 'without-slur)) $ lilypond toto.ly GNU LilyPond 2.15.20 Traitement de « toto.ly » Analyse... without-slur option: #f Success: compilation successfully completed $ lilypond -dwithout-slur toto.ly GNU LilyPond 2.15.20 Avertissement : option interne inconnue : without-slur Traitement de « toto.ly » Analyse... without-slur option: #t Success: compilation successfully completed You will have a warning for each unrecognized option. _______________________________________________ lilypond-user mailing list [email protected] https://lists.gnu.org/mailman/listinfo/lilypond-user
