NAME

Router::PathInfo - PATH_INFO router, based on search trees

DESCRIPTION

Allows balancing PATH_INFO to static and controllers. It has a simple and intuitive interface.

SYNOPSIS

use Router::PathInfo;

# or
use Router::PathInfo as => singletone;
# this allow to call after new: instance, clear_singleton

my $r = Router::PathInfo->new( 
    static => {
        allready => {
            path => '/path/to/static',
            first_uri_segment => 'static'
        }
    }
);
    
$r->add_rule(
    connect         => '/foo/:enum(bar|baz)/:re(^\d{4}$)/:any', 
    action          => $some_thing,
    mthods          => ['GET','DELETE'],
    match_callback  => $code_ref
);

my $env = {PATH_INFO => '/foo/bar/2011/baz', REQUEST_METHOD => 'GET'};

my $res = $r->match($env);
# or
my $res = $r->match('/foo/bar/2011/baz'); # GET by default

# $res = {
#     type => 'controller',
#     action => $some, # result call $code_ref->($match, $env)
#     segment => ['bar','2011','baz']
# }

$env = {PATH_INFO => '/static/img/some.jpg'};

$res = $r->match($env);

# $res = {
#     type  => 'static',
#     file  => '/path/to/static/img/some.jpg',
#     mime  => 'image/jpeg'
# }

PACKAGE VARIABLES

$Router::PathInfo::as_singleton

Mode as singletone. By default - 0. You can pick up directly, or:

use Router::PathInfo as => singletone;
# or
require Router::PathInfo;
Router::PathInfo->import(as => singletone);
# or
$Router::PathInfo::as_singleton = 1

If you decide to work in singletone mode, raise the flag before the call to new.

SINGLETON

When you work in a mode singletone, you have access to methods: instance and clear_singleton

METHODS

new(static => $static)

Constructor. All arguments optsioanlny.

static - it hashref arguments for the constructor Router::PathInfo::Static

add_rule

See add_rule from Router::PathInfo::Controller

match({PATH_INFO => $path_info, REQUEST_METHOD => 'GET'})

Search match. Initially checked for matches on static, then according to the rules of the controllers. In any event returns hashref coincidence or an error.

Example:

{
  type  => 'error',
  code => 400,
  desc  => '$env->{PATH_INFO} not defined'  
}

{
  type  => 'error',
  code => 404,
  desc  => sprintf('not found for PATH_INFO = %s with REQUEST_METHOD = %s', $env->{PATH_INFO}, $env->{REQUEST_METHOD}) 
}

{
    type => 'controller',
    action => $action,
    segment => $array_ref_of_segments 
}

{
    type  => 'static',
    file  => $serch_file,
    mime  => $mime_type
}
