Config::PL - Using '.pl' file as a configuration
use Config::PL;
my $config = config_do 'config.pl';
my %config = config_do 'config.pl';
Config::PL is a utility module for using '.pl' file as a configuration.
This module provides config_do function for loading '.pl' file.
Using '.pl' file which returns HashRef as a configuration is a good idea. We can write flexible and DRY configuration by it. (But, sometimes it becomes too complicated :P)
do "$file" idiom is often used for loading configuration.
But, there is some problems and Config::PL cares these problems.
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.
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';
