SongPath and FilePath variables

[bvdp]

I've added 2 variables:

   $SongPath -- the absolute path name of the song (from the command line)
   $FilePath -- abs path of the current file being processed (could be a lib/include file)

These can be handy if you want to have test code in a library file. So, in the lib file:

   bunch of settings
   defgroove SOMETHING

    if eq $SongPath $FilePath
       do test code
    endif


To add to an existing mma just do the following:

  1. to the top macro.py in the list of includes:
      from os import path

   2. Around line 112 add:
     
        elif s == 'FILEPATH':
            if gbl.inpath.fname == 1:
                return "STDIN"
            else:
                return path.abspath(gbl.inpath.fname)

        elif s == 'SONGPATH':
            if gbl.infile == 1:
                return "STDIN"
            else:
                return path.abspath(gbl.infile)
       

thanks sciurius for this. I think that a new mma-19.x is closer than I thought At least a devel version

May I suggest to return "-" instead of "STDIN" for standard input?

[bvdp]

either works for me. STDIN "could" be a filename ...

If my memory serves, the file '-' is also possible, but probably not. Hard to create

So, in that case I think that we'll change all 3 (FILENAME, SONGPATH and FILEPATH) to '-' if it's coming from stdin. Easy

[sciurius]

A file with name "-" is easy to create, try 'touch ./-'.
If it is really matters, returning an empty string would be best.

[bvdp]

Empty is better, I think.

[bvdp]

So, that's done

Added are $_SongPath, $_FilePath and $_FileName (that was there all along, but not documented). They all return '' if input is coming from stdin.

Also, have added $_Env(..) which returns the value of an env (shell) variable. If the variable doesn't exist or if it has no value a empty string is returned.

Good work! Thanks!

Time to roll out a devel version so we can sync sources for future development?

[bvdp]

Yes it is. I just want to integrate you pluginUtils patch! On my list for today.
