NAME

POE::Component::CPAN::LinksToDocs::No404s::Remember - non-blocking wrapper around CPAN::LinksToDocs::No404s::Remember module

SYNOPSIS

use strict;
use warnings;

use POE qw(Component::CPAN::LinksToDocs::No404s::Remember);

my $poco = POE::Component::CPAN::LinksToDocs::No404s::Remember->spawn;

POE::Session->create(
    package_states => [ main => [qw(_start response )] ],
);

$poe_kernel->run;

sub _start {
    $poco->link_for( {
            tags => 'map,RE,Acme::BabyEater,POE',
            event => 'response',
        }
    );
}

sub response {
    print "$_\n" for @{ $_[ARG0]->{response} };

    $poco->shutdown;
}

Using event based interface is also possible of course.

DESCRIPTION

The module is a non-blocking wrapper around CPAN::LinksToDocs::No404s::Remember module which provides interface to lookup documentation by eating either predefined tags or module names

CONSTRUCTOR

spawn

my $poco = POE::Component::CPAN::LinksToDocs::No404s::Remember->spawn;

POE::Component::CPAN::LinksToDocs::No404s::Remember->spawn(
    alias => 'linker',
    obj_args => {
        tags => { foos => 'bars' },
        db_file => 'some_file.db',
    },
    options => {
        debug => 1,
        trace => 1,
        # POE::Session arguments for the component
    },
    debug => 1, # output some debug info
);

The spawn method returns a POE::Component::CPAN::LinksToDocs::No404s::Remember object. It takes a few arguments, all of which are optional. The possible arguments are as follows:

alias

POE::Component::CPAN::LinksToDocs::No404s::Remember->spawn(
    alias => 'linker'
);

Optional. Specifies a POE Kernel alias for the component.

obj_args

POE::Component::CPAN::LinksToDocs::No404s::Remember->spawn(
    obj_args => {
        tags => { foos => 'bars', },
        db_file => 'some_file.db',
    },
);

The obj_args argument takes a hashref as a value which will be dereferenced directly into CPAN::LinksToDocs::No404s::Remember constructor. See documentation for the constructor of CPAN::LinksToDocs::No404s::Remember module for possible arguments this hashref can contain.

options

my $poco = POE::Component::CPAN::LinksToDocs::No404s::Remember->spawn(
    options => {
        trace => 1,
        default => 1,
    },
);

Optional. A hashref of POE Session options to pass to the component's session.

debug

my $poco = POE::Component::CPAN::LinksToDocs::No404s::Remember->spawn(
    debug => 1
);

When set to a true value turns on output of debug messages. Defaults to: 0.

METHODS

$poco->link_for( {
        event => 'event_for_output',
        tags  => 'map,RE,Acme::BabyEater,POE',
        _blah => 'pooh!',
        session => 'other',
    }
);

Takes a hashref as an argument, does not return a sensible return value. See link_for event's description for more information.

session_id

my $poco_id = $poco->session_id;

Takes no arguments. Returns component's session ID.

shutdown

$poco->shutdown;

Takes no arguments. Shuts down the component.

ACCEPTED EVENTS

$poe_kernel->post( linker => link_for => {
        event   => 'event_for_output',
        tags    => 'map,RE,Acme::BabyEater,POE',
        _blah   => 'pooh!',
        session => 'other',
    }
);

Instructs the component to fetch some docs for the tags or module names you specify. Takes a hashref as an argument, the possible keys/value of that hashref are as follows:

event

{ event => 'results_event', }

Mandatory. Specifies the name of the event to emit when results are ready. See OUTPUT section for more information.

tags

{ tags => 'map,RE,Acme::BabyEater,POE' }

Mandatory. Takes a scalar string containing comma separated predefined tags or module names. For list of predefined tags see CPAN::LinksToDocs.

session

{ session => 'other' }

{ session => $other_session_reference }

{ session => $other_session_ID }

Optional. Takes either an alias, reference or an ID of an alternative session to send output to.

user defined

{
    _user    => 'random',
    _another => 'more',
}

Optional. Any keys starting with _ (underscore) will not affect the component and will be passed back in the result intact.

shutdown

$poe_kernel->post( linker => 'shutdown' );

Takes no arguments. Tells the component to shut itself down.

OUTPUT

$VAR1 = {
    'response' => [
        'http://perldoc.perl.org/functions/map.html',
        'http://perldoc.perl.org/functions/grep.html',
        'http://search.cpan.org/perldoc?Acme::BabyEater',
        'Not found'
    ],
    'tags' => 'map,grep,Acme::BabyEater,Zoffer',
    '_user' => 'foos',
};

The event handler set up to handle the event which you've specified in the event argument to link_for() method/event will recieve input in the $_[ARG0] in a form of a hashref. The possible keys/value of that hashref are as follows:

response

{
    'response' => [
        'http://perldoc.perl.org/functions/map.html',
        'http://perldoc.perl.org/functions/grep.html',
        'http://search.cpan.org/perldoc?Acme::BabyEater',
        'Not found'
    ],
}

The response key will contain a (possibly empty) arrayref of links to documentation. This is the same arrayref that you would get from CPAN::LinksToDocs::No404s::Remember's link_for() method. See documentation for CPAN::LinksToDocs::No404s::Remember module for more information.

tags

{ 'tags' => 'map,grep,Acme::BabyEater,Zoffer', }

The tags key will contain whatever you've passed in tags argument to link_for() method/event.

user defined

{ '_blah' => 'foos' }

Any arguments beginning with _ (underscore) passed into the link_for() event/method will be present intact in the result.
