17 This interface to option setting is meant for setting options are
18 useful to a limited audience. The reason for this interface is that
19 making command line options clutters up the command-line option name
23 preferably, also dont use TESTING_LEVEL_GLOBAL, since it defeats
24 another purpose of this very versatile interface, which is to
25 support multiple debug/testing options concurrently.
30 /* Write midi as formatted ascii stream? */
31 bool midi_debug_global_b;
33 /* General purpose testing flag */
34 int testing_level_global;
37 crash if internally the wrong type is used for a grob property.
39 bool internal_type_checking_global_b;
45 @item -T,--no-timestamps
46 don't timestamp the output
49 Switch on any experimental features. Not for general public use.

60 if (var == ly_symbol2scm ("help"))
62 cout << _("lilypond -e EXPR means
64 evalute EXPR as Scheme after init.scm has been read. In particular,
65 the function set-lily-option allows for access to some internal
68 (set-lily-option SYMBOL VAL)
70 possible options for SYMBOL are :
73 cout << " help (any-symbol)"<<endl;
74 cout << " internal-type-checking (boolean)"<<endl;
75 cout << " midi-debug (boolean)"<<endl;
76 cout << " testing-level (int)"<<endl;

88 else if (var == ly_symbol2scm ("internal-type-checking"))
90 internal_type_checking_global_b = to_boolean (val);
92 else if (var == ly_symbol2scm ("find-old-relative"))
95 Seems to have been broken for some time!

98 show all changes needed to convert a file to relative octave syntax.
