config(4)

NAME
config - Configuration file.

DESCRIPTION

A configuration file contains values for configuration parameters for the applications in the system. The erl command line argument -config Name tells the system to use data in the system configuration file Name.config.

Configuration parameter values in the configuration file will override the values in the application resource files (see app(4)). The values in the configuration file can be overridden by command line flags (see erl(1)).

The value of a configuration parameter is retrieved by calling application:get_env/1, 2.

FILE SYNTAX

The configuration file should be called Name.config where Name is an arbitrary name.

The .config file contains one single Erlang term. The file has the following syntax:
[{Application1, [{Par11, Val11}, ..]},
 ..
 {ApplicationN, [{ParN1, ValN1}, ..]}].

    *   Application = atom() is the name of the application.

    *   Par = atom() is the name of a configuration parameter.

    *   Val = term() is the value of a configuration parameter.
