=head1 NAME
Catalyst::DispatchType::Regex - Regex DispatchType
=head1 SYNOPSIS
See L<Catalyst::DispatchType>.
=head1 DESCRIPTION
Dispatch type managing path-matching behaviour using regexes. For
more information on dispatch types, see:
=over 4
=item * L<Catalyst::Manual::Intro> for how they affect application authors
=item * L<Catalyst::DispatchType> for implementation information.

=head1 METHODS
=head2 $self->list($c)
Output a table of all regex actions, and their private equivalent.
=cut
sub list {
my ( $self, $c ) = @_;
my $avail_width = Catalyst::Utils::term_width() - 9;
my $col1_width = ($avail_width * .50) < 35 ? 35 : int($avail_width * .50);
my $col2_width = $avail_width - $col1_width;
my $re = Text::SimpleTable->new(
[ $col1_width, 'Regex' ], [ $col2_width, 'Private' ]
);
for my $regex ( @{ $self->_compiled } ) {
my $action = $regex->{action};
$re->row( $regex->{path}, "/$action" );
}
$c->log->debug( "Loaded Regex actions:\n" . $re->draw . "\n" )
if ( @{ $self->_compiled } );
}
=head2 $self->match( $c, $path )
Checks path against every compiled regex, and offers the action for any regex
which matches a chance to match the request. If it succeeds, sets action,
match and captures on $c->req and returns 1. If not, returns 0 without
altering $c.
=cut
sub match {
my ( $self, $c, $path ) = @_;
return if $self->SUPER::match( $c, $path );
# Check path against plain text first
foreach my $compiled ( @{ $self->_compiled } ) {
if ( my @captures = ( $path =~ $compiled->{re} ) ) {
next unless $compiled->{action}->match($c);
$c->req->action( $compiled->{path} );
$c->req->match($path);
$c->req->captures( \@captures );
$c->action( $compiled->{action} );
$c->namespace( $compiled->{action}->namespace );
return 1;
}
}
return 0;
}
=head2 $self->register( $c, $action )
Registers one or more regex actions for an action object.
Also registers them as literal paths.
Returns 1 if any regexps were registered.
=cut
sub register {
my ( $self, $c, $action ) = @_;
my $attrs = $action->attributes;
my @register = @{ $attrs->{'Regex'} || [] };
foreach my $r (@register) {
$self->register_path( $c, $r, $action );
$self->register_regex( $c, $r, $action );
}
return 1 if @register;
return 0;
}
=head2 $self->register_regex($c, $re, $action)
Register an individual regex on the action. Usually called from the
register method.
=cut
sub register_regex {
my ( $self, $c, $re, $action ) = @_;
push(
@{ $self->_compiled }, # and compiled regex for us
{
re => qr#$re#,
action => $action,
path => $re,
}
);
}
=head2 $self->uri_for_action($action, $captures)
returns a URI for this action if it can find a regex attributes that contains
the correct number of () captures. Note that this may function incorrectly
in the case of nested captures - if your regex does (...(..))..(..) you'll
need to pass the first and third captures only.
=cut
sub uri_for_action {
my ( $self, $action, $captures ) = @_;
if (my $regexes = $action->attributes->{Regex}) {
REGEX: foreach my $orig (@$regexes) {
my $re = "$orig";
$re =~ s/^\^//;
$re =~ s/\$$//;
$re =~ s/\\([^\\])/$1/g;
my $final = '/';
my @captures = @$captures;
while (my ($front, $rest) = split(/\(/, $re, 2)) {
last unless defined $rest;
($rest, $re) =
Text::Balanced::extract_bracketed("(${rest}", '(');
next REGEX unless @captures;
$final .= $front.shift(@captures);
}
$final .= $re;
next REGEX if @captures;
return $final;
}
}
return undef;
