Linux configuration file libraries [closed]

Questions:

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.

Answers:

You could try glib’s key-value-file-parser

Answers:

I would recommend ‘libconfig‘.

Another option is Boost.PropertyTree (doc). It allows to read/write XML, INI, JSON and Info files. And you get portability for free.

Answers:

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.

Answers:

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.

Answers:

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.

Answers:

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/ .
