A configuration library.

Project description

profig is a configuration library for Python.


Why another configuration library? The simple answer is that none of the available options gave me everything I wanted, with an API that I enjoyed using. This library is as close to my ideal as I have been able to come. It tries to provide some (but not too much) powerful functionality, without sacrificing simplicity.


  • Automatic value conversion.
  • Simple section nesting.
  • Dict-like access.
  • Easily extensible input/output formats.
  • Preserves ordering and comments of config files.
  • Supports Python 2.7+ and 3.2+.


profig installs easily using easy_install or pip:

$ pip install profig


Basic usage is cake. Let’s assume our config file looks like this:

host =
port = 9090

First, we specify the defaults and types to expect:

>>> cfg = profig.Config('server.cfg')
>>> cfg.init('', 'localhost')
>>> cfg.init('server.port', 8080)

Then, we sync our current state with the state of the config file:

>>> cfg.sync()

As expected, we can access the values directly without any extra effort, either directly:

>>> cfg['']

Or by section:

>>> server_cfg = cfg.section('server')
>>> server_cfg['port']
