Mojolicious::Plugin::Config(3)

NAME
Mojolicious::Plugin::Config - Perl-ish configuration plugin

SYNOPSIS
  # myapp.conf (it's just Perl returning a hash)
  {
    # Just a value
    foo => "bar",

    # Nested data structures are fine too
    baz => ['♥'],

    # You have full access to the application
    music_dir => app->home->rel_dir('music')
  };

  # Mojolicious
  my $config = $app->plugin('Config');
  say $config->{foo};

  # Mojolicious::Lite
  my $config = plugin 'Config';
  say $config->{foo};

  # foo.html.ep
  %= $config->{foo}

  # The configuration is available application-wide
  my $config = app->config;
  say $config->{foo};

  # Everything can be customized with options
  my $config = plugin Config => {file => '/etc/myapp.stuff'};

DESCRIPTION
Mojolicious::Plugin::Config is a Perl-ish configuration plugin.

The application object can be accessed via $app or the "app" function, strict, warnings, utf8 and Perl 5.10 features are automatically enabled. You can extend the normal configuration file "$moniker.conf" with "mode" specific ones like "$moniker.$mode.conf". A default configuration filename will be generated from the value of "moniker" in Mojolicious.

The code of this plugin is a good example for learning to build new plugins, you're welcome to fork it.

See "PLUGINS" in Mojolicious::Plugins for a list of plugins that are available by default.
