NAME

Config::PL - Using '.pl' file as a configuration

SYNOPSIS

    use Config::PL;
    my $config = config_do 'config.pl';
    my %config = config_do 'config.pl';

DESCRIPTION

Config::PL is a utility module for using '.pl' file as a configuration.

This module provides config_do function for loading '.pl' file.

Using '.pl' file which returns HashRef as a configuration is a good idea. We can write flexible and DRY configuration by it. (But, sometimes it becomes too complicated :P)

do "$file" idiom is often used for loading configuration.

But, there is some problems and Config::PL cares these problems.

Ensure returns HashRef

do EXPR function of Perl core is not sane because it does not die when the file contains errors or is not found.

config_do function croaks errors and ensures that the returned value is HashRef.

Expected file loading

do "$file" searches files in @INC. It sometimes causes intended file loading.

config_do function limits the search path only in cwd and dirname(__FILE__).

You can easily load another configuration file in the config files as follows.

    # config.pl
    use Config:PL;
    config_do "$ENV{PLACK_ENV}.pl";

You need not write do File::Spec->catfile(File::Basename::dirname(__FILE__), 'config.pl') ... any more!

You can add search path by specifying path as follows. (EXPERIMENTAL)

    use Config::PL ':path' => '/path/config/dir';

THIS SOFTWARE IS IN ALPHA QUALITY. IT MAY CHANGE THE API WITHOUT NOTICE.

FUNCTION

my ($conf|%conf) = config_do $file_name;

Loading configuration from '.pl' file.
