Initialize the profile system. You may use the following arguments to
configure the profile system:
============= ============ ============
Argument Default Description
============= ============ ============
portable ``False`` If True, the profile system will create a profile path within the root folder, allowing the application to work as a portable app.
profile ``default`` The name of the profile to load.
sources ``[]`` A list of additional sources for the path system to use. These will be fed into :func:`siding.path.add_source`, along with any sources from the command line.
profile_path If this is set, load the profile from this path rather than building a path.
root_path The application root directory. This is always the last source to be used by the path system.
============= ============ ============
.. warning::
``root_path`` will *probably* not work as expected after your
application is frozen into an executable, so be sure to test that it's
working properly before distributing your application if you're using
``root_path``.
In addition, you can provide a list of command line arguments to have
siding load them automatically. Example::
siding.profile.initialize(sys.argv[1:])
The following command line arguments are supported:
=================== ============
Argument Description
=================== ============
``--portable`` If True, the profile system will create a profile path within the root folder, allowing the application to work as a portable app.
``--profile`` The name of the profile to load.
``--profile-path`` The path to load the profile from.
``--root-path`` The application root directory.
``--source`` An additional source for the path system. This can be used multiple times.
