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'
            }
        },
        cache_limit => 300
    );
    
    $r->add_rule(
        connect         => '/foo/:enum(bar|baz)/:name(year):re(^\d{4}$)/: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)
    #     name_segments => {'year' => 2011}
    # }
    
    
    $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, cache_limit => $cache_limit)

Constructor. All arguments optsioanlny.

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

cache_limit - limit of matches stored by the rules contain tokens :re and :any, statics and errors. By default - 200. All matches (that occur on an accurate description) cached without limit.

add_rule

See add_rule from Router::PathInfo::Controller

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

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