=head1 NAME

App::Rad::Plugin::ConfigLoader - Load config files of various types


=head1 VERSION

Version 0.01


=head1 SYNOPSIS

    use App::Rad qw(ConfigLoader);

That's it. Now you can use the usual C<< $c->load_config() >> method to load your application's configuration file in any format supported by Config::Any (Apache-like, JSON, YAML, XML, Windows INI, etc).

    $c->load_config('somefile.yml');

Then just access its items through the regular C<< $c->config >> hash.


=head1 DESCRIPTION

Although C<< App::Rad >>'s standard C<< $c->load_config() >> method intends to be intuitive and somewhat flexible for simple configuration files, you may need something more sofisticated or standardized for your applications.

This module extends L<App::Rad>'s functionality by letting you use C<< Config::Any >> to load configuration files of various types transparently.

Please refer to L<Config::Any> for more information on acepted file formats.


=head2 Loading configuration files

This plugin overrides C<< App::Rad >>'s standard C<< $c->load_config >> methodto support different file formats according to their file extension while providing the same syntax.

=head3 $c->load_config( FILE [,FILE2, FILE3, ...] )

Different files can have different extensions and they all should load transparently in order to be accessed via C<< $c->config >>.
