"""
|
||||
This module is based on a rox module (LGPL):
|
||||
|
||||
http://cvs.sourceforge.net/viewcvs.py/rox/ROX-Lib2/python/rox/basedir.py?rev=1.9&view=log
|
||||
|
||||
The freedesktop.org Base Directory specification provides a way for
|
||||
applications to locate shared data and configuration:
|
||||
|
||||
http://standards.freedesktop.org/basedir-spec/
|
||||
|
||||
(based on version 0.6)
|
||||
|
||||
This module can be used to load and save from and to these directories.
|
||||
|
||||
Typical usage:
|
||||
|
||||
from rox import basedir
|
||||
|
||||
for dir in basedir.load_config_paths('mydomain.org', 'MyProg', 'Options'):
|
||||
print "Load settings from", dir
|
||||
|
||||
dir = basedir.save_config_path('mydomain.org', 'MyProg')
|
||||
print >>file(os.path.join(dir, 'Options'), 'w'), "foo=2"
|
||||
|
||||
Note: see the rox.Options module for a higher-level API for managing options.
