Keeper - a configuration storage and retrieval library

General

What is Keeper

The keeper library gives an extremely simple interface for reading and writing configuration data. For example to save and restore the settings in a program. Data is stored in multiple text files, in a hierarchical system.

Keeper is (C) under the GNU LGPL (see the file COPYING).

Latest versions

Stable version: 1.0

Development version: -

Features

Simple to use C interface
Configuration is stored in text-files
Standalone, no dependency to other libraries
Multi-thread safe implementation
Comes with a command line based, and a GTK based database manipulation program
Fast operation with cached data
Per user, per host and global configurations
Ability to store private and public data

Plans for the future

Win32 portability: keeper interface to the Windows registry
Integration with glib
Bindings for other languages (Java, etc...)

Example

Storing a value needs 2 function calls, retrieving a value needs 1 function call. It is simple, isn't it? Here is one example:

#include <keeper.h>

void set_value()
{
        char *value = "Hello";

        kp_set_string("u/testdir/testprog:/abc", value);
        kp_flush();
}

void get_value()
{
        char *value = NULL;

        kp_get_string("u/testdir/testprog:/abc", &value);
	...
}

Documentation

The documentation is in the form of man pages, which can also be viewed here:

Distribution version: 1.0

Version 1.0 of keeper is finally here. I've tested it rather extensively, so hopefully no bugs are left in it.
