I'm wondering about the behaviour of ly:add-option If I have the following file:
\version "2.19.47" #(ly:add-option 'humdrum-file #f "Set to the file name of a Humdrum file") #(display (ly:get-option 'humdrum-file)) and invoke LilyPond with the command line option -dmy-option=my-value The display is #f or whatever I set as default value in ly:add-option. If I comment out the ly:add-option line I get the correct value displayed but also a warning "no such internal option: my-option". I thought I could use that line to suppress the warning and preset the option with a default value that it will have when the option isn't passed on the command line. But I have the impression that ly:add-option *overwrites* any value passed through the command line. What am I missing?
