如何从Python脚本获取X字体路径？

Question

From a Python script that is started under X, I want to get the font path.

The script passes the font path to Xvnc (part of TightVNC and TigerVNC). Yes, I know, to start a VNC server, one can use startvnc , which takes care of setting up the font path. However, startvnc does some things that are not desired in this case. Also, I want to use the exact same font path as on the X server that the script is started on.

I considered parsing the output of xset q . However:

• I don't know how reliable that is, ie if output is always formatted the same way.

• The output may contain placeholders that are not actually paths. For example, built-ins in: /usr/share/fonts/misc,/usr/share/fonts/Type1,built-ins

Answer 1

From reading the manual for xorg.conf, your safest bet would be to parse the configuration file (which I'm assuming setx q parses) for FontPath lines, which look like:

FontPath "path" sets the search path for fonts. This path is a comma separated list of font path elements which the Xorg server searches for font databases.

Using python's re module, the font paths (because multiple FontPath s can be specified) can be parsed like this:

import re
regex = re.compile(r'^\s*FontPath\s+(.*)\s*$', re.MULTILINE)

with open('xorg.conf') as f:
    data = f.read()
matches = regex.findall(data)
