Re: try except in lilypond

Can I look for files in the included directories with scheme? Or can I get the includepath names to search there myself? _Function:_ *ly:find-file*/name/ Return the absolute file name of name, or |#f| if not found. -- Timothy Lanfear, Bristol, UK. __

Hi Timothy, > (if (access? "somepath.ily" R_OK) >(ly:parser-include-string "\\include \"somepath.ily\"")) Thanks a lot! That works. One follow-up problem is, that the include path is found via the -I command line option. So somepath.ily does not exist (relative to where I execute lilypond)

Re: try except in lilypond

Hi Mike, Andrew and David, thanks for your suggestions and help. My question was driven by the intention to write a score in one file that can be shared and compiled standalone and can optionally include my custom settings and fonts. This way, I could share it and it would probably look best with

try except in lilypond

Hi, is there something like try ... except in lilypond. What I want to achieve is some failure tolerance in ly files. I want to load some fonts or include files and if they don't exist, it should just be skipped without stopping the compilation (perhaps a warning could be printed). Is
