15   How can I change the path delimiter from a space ' ' to a slash '/'?
16       When importing the Path::Dispatcher::Declarative sugar, specify the
17       "token_delimiter" option for the "default" group.
18
19           package My::Dispatcher;
20           use Path::Dispatcher::Declarative -base, -default => {
21               token_delimiter => '/',
22           };
23
24       Or define a subclass of Path::Dispatcher::Declarative with a
25       "token_delimiter" method:
26
27           package Web::Dispatcher::Maker;
28           use base 'Path::Dispatcher::Declarative';
29
30           use constant token_delimiter => '/';
31
32
33           package My::Dispatcher;
34           use Web::Dispatcher::Maker -base;
35
36   How can I do rule chaining (like in Catalyst)?
37       You can use a "chain" rule approximate chaining behavior:
38
39           package MyDispatcher;
40           use Path::Dispatcher::Declarative -base;
41
42           under show => sub {
43               chain {
44                   print "Displaying ";
45               };
46               on inventory => sub {
47                   print "inventory:\n";
48                   ...
49               };
50               on score => sub {
51                   print "score:\n";
52                   ...
53               };
54           };
55
56           package main;
57
58           MyDispatcher->run("show inventory"); # "Displaying inventory:\n ..."
59
60           MyDispatcher->run("show score"); # "Displaying score:\n ..."
61
62   How can I configure tab completion for shells?
63       First add a dispatcher rule for generating completions based on the
64       path. Here we name it _gencomp, so that if the user types "app _gencomp
65       hel" it will print out the various completions of "hel".
66
67           on qr/^_gencomp\s*(.*)/ => sub {
68               my $prefix = shift->pos(1);
69               $prefix = "" if !defined($prefix);
70               print "$_\n" for dispatcher->complete($prefix);
71           };
72
73       Then tell your shell about how to use _gencomp. For zsh it might look
74       like this (replace "APP" with your binary name):
75
76           /usr/share/zsh/site-functions/_APP:
77               #compdef APP
78               typeset -a APP_completions
79               APP_completions=($($words[1] _gencomp $words[2,-1]))
80               compadd $APP_completions
81
82       For bash it might look like this:
83
84           /etc/bash_completion.d/APP.bash:
85               function _APP_()
86               {
87                   COMPREPLY=($($1 _gencomp ${COMP_WORDS[COMP_CWORD]}))
88               }
89
90               complete -F _APP_ APP
