Project Description

libconf is a pure-Python reader/writer for configuration files in libconfig format, which is often used in C/C++ projects. It’s interface is similar to the json module: the four main methods are load(), loads(), dump(), and dumps().

Example usage:

import libconf
>>> with open('example.cfg') as f:
...     config = libconf.load(f)
>>> config
{'capabilities': {'can-do-arrays': [3, 'yes', True],
                  'can-do-lists': (True,
                                   14880,
                                   ('sublist',),
                                   {'subgroup': 'ok'})},
 'version': 7,
 'window': {'position': {'h': 600, 'w': 800, 'x': 375, 'y': 210},
            'title': 'libconfig example'}}

>>> config['window']['title']
'libconfig example'
>>> config.window.title
'libconfig example'

>>> print(libconf.dumps({'size': [10, 15], 'flag': True}))
flag = True;
size =
[
    10,
    15
];

The data can be accessed either via indexing (['title']) or via attribute access .title.

Character encoding and escape sequences

The recommended way to use libconf is with Unicode objects (unicode on Python2, str on Python3). Input strings or streams for load() and loads() should be Unicode, as should be all strings contained in data structures passed to dump() and dumps().

In load() and loads(), escape sequences (such as \n, \r, \t, or \xNN) are decoded. Hex escapes (\xNN) are mapped to Unicode characters U+0000 through U+00FF. All other characters are passed though as-is.

In dump() and dumps(), unprintable characters below U+0080 are escaped as \n, \r, \t, \f, or \xNN sequences. Characters U+0080 and above are passed through as-is.

Comparison to other Python libconfig libraries

Pylibconfig2 is another pure-Python libconfig reader. It’s API is based on the C++ interface, instead of the Python json module. It’s licensed under GPLv3, which makes it unsuitable for use in a large number of projects.

Python-libconfig is a library that provides Python bindings for the libconfig++ C++ library. While permissively licensed (BSD), it requires a compilation step upon installation, which can be a drawback.

I wrote libconf (this library) because both of the existing libraries didn’t fit my requirements. I had a work-related project which is not open source (ruling out pylibconfig2) and I didn’t want the deployment headache of python-libconfig. Further, I enjoy writing parsers and this seemed like a nice opportunity :-)
