libConfuse is a configuration file parser library, licensed under the terms of the ISC license, and written in C. It supports sections and (lists of) values (strings, integers, floats, booleans or other sections), as well as some other features (such as single/double-quoted strings, environment variable expansion, functions and nested include statements). It makes it very easy to add configuration file capability to a program using a simple API.
The goal of libConfuse is not to be the configuration file parser library with a gazillion of features. Instead, it aims to be easy to use and quick to integrate with your code.
libConfuse was called libcfg before, but was changed to not confuse with other similar libraries.
Please report bugs to the GitHub issue tracker. If you want to contribute fixes or new features, see the file CONTRIBUTING.md.
Example configuration files:
- test.conf and the source code shows most of the features of confuse, including lists and functions.
- simple.conf shows how to use the "simple" versions of options. See the corresponding source.
The source code is distributed in three files: Two tarballs in .tar.gz and .tar.xz formats with source code and Makefiles for UNIX systems, and a .zip file with Windows build files.
- confuse v3.2: UNIX tar.gz, Windows ZIP
- New releases
- Old releases
libConfuse employs the GNU configure and build system. Simply enter ./configure --help to list available options and see the INSTALL file for the full installation instructions.
When checking out the code from GitHub, use ./autogen.sh to
generate a configure script.
For the time being, the following documentation is published at the old homepage, but also distributed with the source:
- API reference/manual (generated with doxygen)
- Tutorial (a work in progress)
- ChangeLog (check what's new!)
