open() on OS X (Read 318 times)

open() on OS X
Aug 19^th, 2008, 2:07pm

Hello there,

I'm trying to use Processing to either invoke Lilypond (music notation software) on Mac OS X.

So far I've tried the following:

1) Trying to call the lilypond program from within its main package:

String[] args = {"/Users/mac/Desktop/lilypond.app/contents/resources/bin/lilypond","--pdf","/Use
rs/mac/Documents/Processing/Folping/test.ly"};
open(args);

2) Trying to call sh and a shell script (I've tested the script - works fine from Bash):

String[] args = {"sh","","makelily.sh"};
open(args);

Am I doing something wrong here? The complete lack of feedback in the debug window isn't really helping matters!

Any aid appreciated,

P

Thanks, Fry. That works so far as launching Lilypond editor goes. Unfortunately it's a script within the .app package that I need to call, which compiles files into notation. For example:

/Users/mac/Desktop/lilypond.app/contents/resources/bin/lilypond --pdf test.ly

- the above works fine as a shell script - is there any way to get around this with Processing's insistence on using open?

But you can use Runtime.exec() from Java, or exec() in Processing which is just a shortcut to the same.
