RECIPES

   How can I change the path delimiter from a space ' ' to a slash '/'?
       When importing the Path::Dispatcher::Declarative sugar, specify the "token_delimiter" option for the "default" group.

	   package My::Dispatcher;
	   use Path::Dispatcher::Declarative -base, -default => {
	       token_delimiter => '/',
	   };

       Or define a subclass of Path::Dispatcher::Declarative with a "token_delimiter" method:

	   package Web::Dispatcher::Maker;
	   use base 'Path::Dispatcher::Declarative';

	   use constant token_delimiter => '/';

	   package My::Dispatcher;
	   use Web::Dispatcher::Maker -base;

   How can I do rule chaining (like in Catalyst)?
       You can use a "chain" rule approximate chaining behavior:

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

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

	   package main;

	   MyDispatcher->run("show inventory"); # "Displaying inventory:
 ..."

	   MyDispatcher->run("show score"); # "Displaying score:
 ..."

   How can I configure tab completion for shells?
       First add a dispatcher rule for generating completions based on the path. Here we name it _gencomp, so that if the user types "app _gencomp
       hel" it will print out the various completions of "hel".

	   on qr/^_gencomps*(.*)/ => sub {
	       my $prefix = shift->pos(1);
	       $prefix = "" if !defined($prefix);
	       print "$_
" for dispatcher->complete($prefix);
	   };

       Then tell your shell about how to use _gencomp. For zsh it might look like this (replace "APP" with your binary name):

	   /usr/share/zsh/site-functions/_APP:
	       #compdef APP
	       typeset -a APP_completions
	       APP_completions=($($words[1] _gencomp $words[2,-1]))
	       compadd $APP_completions

       For bash it might look like this:

	   /etc/bash_completion.d/APP.bash:
	       function _APP_()
	       {
		   COMPREPLY=($($1 _gencomp ${COMP_WORDS[COMP_CWORD]}))
	       }

	       complete -F _APP_ APP
