Dancer::Plugin(3pm)					User Contributed Perl Documentation				       Dancer::Plugin(3pm)

NAME

       Dancer::Plugin - helper for writing Dancer plugins

DESCRIPTION

       Create plugins for Dancer

SYNOPSIS

	 package Dancer::Plugin::LinkBlocker;
	 use Dancer ':syntax';
	 use Dancer::Plugin;

	 register block_links_from => sub {
	   my $conf = plugin_setting();
	   my $re = join ('|', @{$conf->{hosts}});
	   before sub {
	       if (request->referer && request->referer =~ /$re/) {
		   status 403 || $conf->{http_code};
	       }
	   };
	 };

	 register_plugin;
	 1;

       And in your application:

	   package My::Webapp;

	   use Dancer ':syntax';
	   use Dancer::Plugin::LinkBlocker;

	   block_links_from; # this is exported by the plugin

PLUGINS

       You can extend Dancer by writing your own Plugin.

       A plugin is a module that exports a bunch of symbols to the current namespace (the caller will see all the symbols defined via "register").

       Note that you have to "use" the plugin wherever you want to use its symbols.  For instance, if you have Webapp::App1 and Webapp::App2, both
       loaded from your main application, they both need to "use FooPlugin" if they want to use the symbols exported by "FooPlugin".

   METHODS
       register
	   Lets you define a keyword that will be exported by the plugin.

	       register my_symbol_to_export => sub {
		   # ... some code
	       };

       register_plugin
	   A Dancer plugin must end with this statement. This lets the plugin register all the symbols define with "register" as exported symbols
	   (via the Exporter module).

	   A Dancer plugin inherits from Dancer::Plugin and Exporter transparently.

       plugin_setting
	   Configuration for plugin should be structured like this in the config.yml of the application:

	     plugins:
	       plugin_name:
		 key: value

	   If "plugin_setting" is called inside a plugin, the appropriate configuration will be returned. The "plugin_name" should be the name of
	   the package, or, if the plugin name is under the Dancer::Plugin:: namespace (which is recommended), the remaining part of the plugin
	   name.

	   Enclose the remaining part in quotes if it contains ::, e.g.  for Dancer::Plugin::Foo::Bar, use:

	     plugins:
	       "Foo::Bar":
		 key: value
