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 $app or the app function, strict, warnings, utf8 and Perl 5.16 features are automatically enabled. A default configuration filename in the application home directory will be generated from the value of "moniker" in Mojolicious ($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.
