Are there any good configuration file reading libraries for C\C++ that can be used for applications written on the linux platform. I would like to have a simple configuration file for my application. At best i would like to steer clear of XML files that might potentially confuse users.
You could try glib’s key-value-file-parser
I would recommend ‘libconfig‘.
Boost program_options This allows you to read program options from config files, environment variables and the command line. It is portable and very easy to use.
If you just want a simple config file, with a list of commands and/or variable settings, then it’s very easy to write your own parser, so easy that it’s probably not worth using a library. If you need something more complicated then the parser rapidly becomes more complicated and an existing library is worth using.
I’ve never tried using libconfig, but it looks like a good choice, and I like the format of the config files it uses.
You need to decide whether you want your program to be able to write config files. If it’s a GUI program, you probably do. This will affect what libraries are suitable.
For a single app, you could consider libconfuse.
If you need to be able to handle a wide variety of config file formats (e.g. for a web portal for a system, which needs to read and write config files from many apps in many formats), there is Augeas.
The question is what file format did you have in mind? The attribute “simple” is a bit of an underspecification.
If you are looking for a library that can use “windows .ini formated” config files you may want to check out ACE http://www.cs.wustl.edu/~schmidt/ACE/ .
