Hi Victor,

I think it would not be too difficult to do this and I thnk this will
work in a way that it won't actually change the directory, just append
to the search path, and even then, only optionally if a flag is
enabled.

The changes would be:

-in csoundCore.h, add one int field to OPARMS (maybe call it relativeToFile)

-in Top/argdecode.c (decode_long), add:

} else if (!(strcmp(s, "relative-to-file"))) {
      O->pathsRelativeToFile = 1;
      return 1;
    }

(if --relative-to-file is an okay name to use)

-in Top/main.c in csoundCompile, in the area of code where it check's
for if it's a CSD being loaded, we could add code like (in
pseudocode):

if(O->relativeToFile) {
  char * dir = csoundGetDirectory(filename);
  csoundAppendEnv(csound, "SADIR", dir);
  csoundAppendEnv(csound, "SSDIR", dir);
  csoundAppendEnv(csound, "INCDIR", dir);
  csoundAppendEnv(csound, "MIDIDIR", dir); // not sure what the name
of this env var is
}

The csoundGetDirectory would be function we could add to envvar.c that
would resolve if a relative path name is given to the current working
directory.

How does this sound?  Completely optional and defaulting to prior
behavior and has no directory changing.
