DESCRIPTION

use config creates a constant in the same way as use constant, but takes the value from the project's local config file if one is specified there.

The config file ./.config.pm is located in the root directory of the project.

The current directory in the project must correspond to the project root.

use config {

The function is used in the config file (./.config.pm) to configure Perl modules. For config it should start with package config;.

    D => 10,
    X => 12,
);

config->import('X' => 15);

D() # => 5
X() # => 12
