Mojolicious::Plugin::NotYAMLConfig - Not quite YAML configuration plugin


# myapp.yml (it's just YAML with embedded Perl)
foo: bar
  - ♥
music_dir: <%= app->home->child('music') %>

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

# Mojolicious::Lite
my $config = plugin 'NotYAMLConfig';
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 NotYAMLConfig => {file => '/etc/myapp.conf'};


Mojolicious::Plugin::NotYAMLConfig is a YAML configuration plugin that preprocesses its input with Mojo::Template. By default it uses CPAN::Meta::YAML for parsing, which is not the best YAML module available, but good enough for most config files. If you need something more correct you can use a different module like YAML::XS with the "module" option.

The application object can be accessed via $app or the app function. A default configuration filename in the application home directory will be generated from the value of "moniker" in Mojolicious ($moniker.yml). You can extend the normal configuration file $moniker.yml with mode specific ones like $moniker.$mode.yml, which will be detected automatically.

These configuration values are currently reserved:


If this configuration value has been set in "config" in Mojolicious when this plugin is loaded, it will not do anything besides loading deployment specific plugins.

  - SetUserGroup:
      user: sri
      group: staff

One or more deployment specific plugins that should be loaded right after this plugin has been loaded.

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.


Mojolicious::Plugin::NotYAMLConfig inherits all options from Mojolicious::Plugin::JSONConfig and supports the following new ones.


# Mojolicious::Lite
plugin NotYAMLConfig => {module => 'YAML::PP'};

Alternative YAML module to use for parsing.


Mojolicious::Plugin::NotYAMLConfig inherits all methods from Mojolicious::Plugin::JSONConfig and implements the following new ones.


$plugin->parse($content, $file, $conf, $app);

Process content with "render" in Mojolicious::Plugin::JSONConfig and parse it with CPAN::Meta::YAML.

sub parse ($self, $content, $file, $conf, $app) {
  $content = $self->render($content, $file, $conf, $app);
  return $hash;


my $config = $plugin->register(Mojolicious->new);
my $config = $plugin->register(Mojolicious->new, {file => '/etc/foo.conf'});

Register plugin in Mojolicious application and merge configuration.
