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:\n";
        ...
    };
    on score => sub {
        print "score:\n";
        ...
    };
};

package main;

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

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

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/^_gencomp\s*(.*)/ => sub {
    my $prefix = shift->pos(1);
    $prefix = "" if !defined($prefix);
    print "$_\n" for dispatcher->complete($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
