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->child('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 $app or the app function, strict, warnings, utf8 and Perl 5.10 features are automatically enabled. A default configuration filename in the application home directory will be generated from the value of "moniker" in Mojolicious ($moniker.conf). You can extend the normal configuration file $moniker.conf with mode specific ones like $moniker.$mode.conf, which will be detected automatically.

If the configuration value config_override has been set in "config" in Mojolicious when this plugin is loaded, it will not do anything.

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.
