Path::Dispatcher::Cookbook - A cookbook for Path::Dispatcher
=head1 RECIPES
=head2 How can I change the path delimiter from a space ' ' to a slash '/'?
When importing the L<Path::Dispatcher::Declarative> sugar, specify the
C<token_delimiter> option for the C<default> group.
package My::Dispatcher;
use Path::Dispatcher::Declarative -base, -default => {
token_delimiter => '/',
};
Or define a subclass of L<Path::Dispatcher::Declarative> with a
C<token_delimiter> method:
package Web::Dispatcher::Maker;
use base 'Path::Dispatcher::Declarative';
use constant token_delimiter => '/';
package My::Dispatcher;
use Web::Dispatcher::Maker -base;
=head2 How can I do rule chaining (like in Catalyst)?
You can use a C<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 ..."
=head2 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
