NAME

       Path::Dispatcher::Declarative - sugary dispatcher

SYNOPSIS

	   package MyApp::Dispatcher;
	   use Path::Dispatcher::Declarative -base;

	   on score => sub { show_score() };

	   on ['wield', qr/^w+$/] => sub { wield_weapon($2) };

	   rewrite qr/^inv/ => "display inventory";

	   under display => sub {
	       on inventory => sub { show_inventory() };
	       on score     => sub { show_score() };
	   };

	   package Interpreter;
	   MyApp::Dispatcher->run($input);

DESCRIPTION

       Jifty::Dispatcher rocks!

KEYWORDS

   dispatcher -> Dispatcher
       Returns the Path::Dispatcher object for this class; the object that the sugar is modifying. This is useful for adding custom rules through
       the regular API, and inspection.

   dispatch path -> Dispatch
       Invokes the dispatcher on the given path and returns a Path::Dispatcher::Dispatch object. Acts as a keyword within the same package;
       otherwise as a method (since these declarative dispatchers are supposed to be used by other packages).

   run path, args
       Performs a dispatch then invokes the "run" in Path::Dispatcher::Dispatch method on it.

   on path => sub {}
       Adds a rule to the dispatcher for the given path. The path may be:

       a string
	   This is taken to mean a single token; creates an Path::Dispatcher::Rule::Tokens rule.

       an array reference
	   This is creates a Path::Dispatcher::Rule::Tokens rule.

       a regular expression
	   This is creates a Path::Dispatcher::Rule::Regex rule.

       a code reference
	   This is creates a Path::Dispatcher::Rule::CodeRef rule.

   under path => sub {}
       Creates a Path::Dispatcher::Rule::Under rule. The contents of the coderef should be nothing other "on" and "under" calls.

   then sub { }
       Creates a Path::Dispatcher::Rule::Always rule that will continue on to the next rule via "next_rule"

       The only argument is a coderef that processes normally (like on).

       NOTE: You *can* avoid running a following rule by using "last_rule".

       An example:

	   under show => sub {
	       then {
		   print "Displaying ";
	       };
	       on inventory => sub {
		   print "inventory:
";
		   ...
	       };
	       on score => sub {
		   print "score:
";
		   ...
	       };

NAME

       Log::Report::Dispatcher::Callback - call a code-ref for each log-line

INHERITANCE

	Log::Report::Dispatcher::Callback
	  is a Log::Report::Dispatcher

SYNOPSIS

	sub cb($$$)
	{   my ($options, $reason, $message) = @_;
	    ...
	}

	dispatcher Log::Report::Dispatcher::Callback => 'cb'
	   , callback => &cb;

	dispatcher CALLBACK => 'cb'   # same
	   , callback => &cb;

DESCRIPTION

       This basic file logger accepts a callback, which is called for each message which is to be logged. When you need complex things, you may
       best make your own extension to Log::Report::Dispatcher, but for simple things this will do.

METHODS

   Constructors
       $obj->close
	   See "Constructors" in Log::Report::Dispatcher

       Log::Report::Dispatcher::Callback->new(TYPE, NAME, OPTIONS)
	    -Option	  --Defined in	   --Default
	     accept	    Log::Report::Dispatcher  depend on mode
	     callback			     <required>
	     charset	    Log::Report::Dispatcher  <undef>
	     format_reason  Log::Report::Dispatcher  'LOWERCASE'
	     locale	    Log::Report::Dispatcher  <system locale>
	     mode	    Log::Report::Dispatcher  'NORMAL'

	   accept => REASONS
	   callback => CODE
	     Your "callback" is called with four parameters: this dispatcher object, the options, a reason and a message.  The "options" are the
	     first parameter of Log::Report::report() (read over there).  The "reason" is a capitized string like "ERROR". Finally, the "message"
	     is a Log::Report::Message.

	   charset => CHARSET
	   format_reason => 'UPPERCASE'|'LOWERCASE'|'UCFIRST'|'IGNORE'|CODE
	   locale => LOCALE
	   mode => 'NORMAL'|'VERBOSE'|'ASSERT'|'DEBUG'|0..3

   Accessors
       $obj->callback
	   Returns the code reference which will handle each logged message.

       $obj->isDisabled
	   See "Accessors" in Log::Report::Dispatcher

	   See "Logging" in Log::Report::Dispatcher

       $obj->collectStack([MAXDEPTH])
       Log::Report::Dispatcher::Callback->collectStack([MAXDEPTH])
	   See "Logging" in Log::Report::Dispatcher
