## Description

This module provides a simple method of retrieving and storing configuration data that resides in files. It also provides the ability to supply default values for the configuration parameters to simply client code.

### Note

The purpose of this module is different in GNOME 2 from what it was in GNOME 1. General applications should use the gnome-gconf module for their configuration requirements.

The gnome-config module exists for applications that

- need to provide a backwards-compatible version of their configuration files, or

- need to run independently of a user and access configuration files at absolute locations (for example, a login manager), or

- need to parse .desktop-style files, or

- need to parse user- or shell-editable/readable files.

Definitions.

- config path: a string that specifies which item to retrieve from the configuration database. The config path is composed of three elements: the first one is the filename where the information is stored, the second component is the section and the third one is the key inside the section

  For example, a config path of "/myapp/toolbox/showit" could be used to retrieve the setting for whether 'myapp' should display its toolbox or not. In this example "myapp" is the file name (which is stored in `~/.gnome2` directory), "toolbox" is the section and "showit" is the key.

  If you want to access an absolute file instead of a `~/.gnome2`-relative file, then you need to surround the filename with equal signs, for example, to access the key "mykey" from the section "mysection" in a configuration file located in `/gnome/var/myconfig` you need to use this path: "=/gnome/var/myconfig=/mysection/mykey".

- default: when retrieving a config item, specifies the value to be used if the item is not found.

- private configuration data: Normally, config item data is located in files under the `~user/.gnome2` directory in a .ini-like format. These files are world-readable. Items that have security or privacy implications are stored and retrieved using the "private" versions of the gnome-config routines, and the data for these items is stored in files under the `~user/.gnome2_private` directory, which is not accessable by anyone except that user and the system administrator.

- translated strings: GNOME's multilingual support means that multiple languages must be supported for configuration items. The gnome_config_*get_translated_string() and gnome_config_*set_translated_string() routines allow you to specify which language a string item should be accessed for.

- section: a group of config items and other config sections

How Config Items are Read. The gnome-config module has a versatile method of storing config items. When a config item is written by a program, it is written to a file under the `~/.gnome2` hierarchy. However, when config items are read, the process is a little more complicated. There are a number of places that are searched. If the config item is not found in one, then the next place is checked, finally falling back to the default value provided by the application. The locations are as follows:

- `$(sysconfdir)/gnome/config-override` - a system administrator would put config items in this directory that they don't want to be configurable.

- `~/.gnome` - this is where the user's config items are written to and is the next place that is searched

- `$(sysconfdir)/gnome/config` - this directory would hold system wide default configuration values.

Possible uses for this are setting system wide defaults such as proxy servers for the system (either using `config-override` to enforce such a policy or the `config` directory to suggest such a default). It is also possible to configure the application through its graphical interface, and then copy the configuration file accross to the appropriate system-wide directory. The `config-override` directory should be used sparingly, as it could annoy or confuse some users. Note also that some applications will not read the config items every time they are needed, so putting defaults into the `config-override` directory will not always completely enforce a setting.

Every function in this module comes in at least two forms. There is the ``gnome_config_get_foo()`` version which retrieves the configuration data from the `~/.gnome2` directory (unless an absolute configuration key is given, as defined above). Then there is the ``gnome_config_private_get_foo()`` version, which retrieves the information from the user's `~/.gnome2-private` directory.

For functions dealing with strings, there is a third form of each function which returns the translated version of the string for the current locale.
