NAME ^

WWW::Pastebin::PastebinCom::Retrieve - retrieve pastes from http://pastebin.com/ website

SYNOPSIS ^

    use strict;
    use warnings;

    use lib '../lib';
    use WWW::Pastebin::PastebinCom::Retrieve;

    die "Usage: perl retrieve.pl <paste_ID_or_URI>\n"
        unless @ARGV;

    my $Paste = shift;

    my $paster = WWW::Pastebin::PastebinCom::Retrieve->new;

    my $results_ref = $paster->retrieve( $Paste )
        or die $paster->error;

    printf "Paste content is:\n%s\nPasted by %s on %s\n",
            @$results_ref{ qw(content name posted_on) };

DESCRIPTION ^

The module provides interface to retrieve pastes from http://pastebin.com/ website via Perl.

CONSTRUCTOR ^

new

    my $paster = WWW::Pastebin::PastebinCom::Retrieve->new;

    my $paster = WWW::Pastebin::PastebinCom::Retrieve->new(
        timeout => 10,
    );

    my $paster = WWW::Pastebin::PastebinCom::Retrieve->new(
        ua => LWP::UserAgent->new(
            timeout => 10,
            agent   => 'PasterUA',
        ),
    );

Constructs and returns a brand new juicy WWW::Pastebin::PastebinCom::Retrieve object. Takes two arguments, both are optional. Possible arguments are as follows:

timeout

    ->new( timeout => 10 );

Optional. Specifies the timeout argument of LWP::UserAgent's constructor, which is used for retrieving. Defaults to: 30 seconds.

ua

    ->new( ua => LWP::UserAgent->new( agent => 'Foos!' ) );

Optional. If the timeout argument is not enough for your needs of mutilating the LWP::UserAgent object used for retrieving, feel free to specify the ua argument which takes an LWP::UserAgent object as a value. Note: the timeout argument to the constructor will not do anything if you specify the ua argument as well. Defaults to: plain boring default LWP::UserAgent object with timeout argument set to whatever WWW::Pastebin::PastebinCom::Retrieve's timeout argument is set to as well as agent argument is set to mimic Firefox.

METHODS ^

retrieve

    my $results_ref = $paster->retrieve('http://pastebin.com/f525c4cec')
        or die $paster->error;

    my $results_ref = $paster->retrieve('f525c4cec')
        or die $paster->error;

Instructs the object to retrieve a paste specified in the argument. Takes one mandatory argument which can be either a full URI to the paste you want to retrieve or just its ID. On failure returns either undef or an empty list depending on the context and the reason for the error will be available via error() method. On success returns a hashref with the following keys/values:

    $VAR1 = {
        'lang' => 'Perl',
        'posted_on' => 'Sat 22 Mar 16:07',
        'content' => 'blah blah content of the paste',
        'name' => 'Zoffix'
    };

content

    { 'content' => 'blah blah content of the paste', }

The content key will contain the actual content of the paste. See also content() method which is overloaded for this class.

lang

    { 'lang' => 'Perl' }

The lang key will contain the (computer) language of the paste (as specified by the person who pasted it)

posted_on

    { 'posted_on' => 'Sat 22 Mar 16:07', }

The posted_on key will contain the date/time when the paste was created.

name

    { 'name' => 'Zoffix' }

The name key will contain the name of the person who created the paste.

error

    $paster->retrieve('http://pastebin.com/f525c4cec')
        or die $paster->error;

On failure retrieve() returns either undef or an empty list depending on the context and the reason for the error will be available via error() method. Takes no arguments, returns an error message explaining the failure.

id

    my $paste_id = $paster->id;

Must be called after a successful call to retrieve(). Takes no arguments, returns a paste ID number of the last retrieved paste irrelevant of whether an ID or a URI was given to retrieve()

uri

    my $paste_uri = $paster->uri;

Must be called after a successful call to retrieve(). Takes no arguments, returns a URI object with the URI pointing to the last retrieved paste irrelevant of whether an ID or a URI was given to retrieve()

results

    my $last_results_ref = $paster->results;

Must be called after a successful call to retrieve(). Takes no arguments, returns the exact same hashref the last call to retrieve() returned. See retrieve() method for more information.

content

    my $paste_content = $paster->content;

    print "Paste content is:\n$paster\n";

Must be called after a successful call to retrieve(). Takes no arguments, returns the actual content of the paste. Note: this method is overloaded for this module for interpolation. Thus you can simply interpolate the object in a string to get the contents of the paste.

ua

    my $old_LWP_UA_obj = $paster->ua;

    $paster->ua( LWP::UserAgent->new( timeout => 10, agent => 'foos' );

Returns a currently used LWP::UserAgent object used for retrieving pastes. Takes one optional argument which must be an LWP::UserAgent object, and the object you specify will be used in any subsequent calls to retrieve().
