AFMPATH environmental variable

OK, so the font files exist and are readable. In order to figure out
where the problem is, I'll need you to add a couple of lines to
matplotlib/backends/backend_ps.py and tell me what the output is. In
the function _get_afm_filenames on line 413, add these print lines
before the return statement and let me know what they report

    print paths
    print fnames
    return fnames

It appears that the following replacement of _get_afm_filenames
works. I'm a python learner so that may lead to other bugs. :slight_smile:

<quote>
     def _get_afm_filenames(self):
         paths = [os.path.join(distutils.sysconfig.PREFIX, 'share', 'matplotlib')]
         if os.environ.has_key('AFMPATH'):
             afmpath = os.environ['AFMPATH']
             ### if afmpath.find(';')>0: #win32 style
             ### paths.extend(afmpath.split(';'))
             ### elif afmpath.find(':')>0: # unix style
             ### paths.extend(afmpath.split(':'))
             ### else:
         paths.append(afmpath)
  fnames = []
         fnames = [fname for fname in get_recursive_filelist(paths)
                   if fname.lower().find('.afm')>0 and
                      os.path.exists(fname)]
  ### start debug
  #print paths
      #print fnames
  ###raw_input("Hit enter to continue -->")
  ### end debug
         return fnames

I'm going to sleep now. :slight_smile:

Good day,
