[![Build Status](https://travis-ci.org/binary-com/perl-pubnub-pubsub.svg?branch=master)](https://travis-ci.org/binary-com/perl-pubnub-pubsub) [![Coverage Status](https://coveralls.io/repos/binary-com/perl-pubnub-pubsub/badge.png?branch=master)](https://coveralls.io/r/binary-com/perl-pubnub-pubsub?branch=master) [![Gitter chat](https://badges.gitter.im/binary-com/perl-pubnub-pubsub.png)](https://gitter.im/binary-com/perl-pubnub-pubsub) # NAME PubNub::PubSub - Perl library for rapid publishing of messages on PubNub.com # SYNOPSIS use PubNub::PubSub; my $pubnub = PubNub::PubSub->new( pub_key => 'demo', # only required for publish sub_key => 'demo', channel => 'sandbox', ); # publish $pubnub->publish({ messages => ['message1', 'message2'], callback => sub { my ($res) = @_; # $res is a L say $res->code; # 200 say Dumper(\$res->json); # [1,"Sent","14108733777591385"] } }); $pubnub->publish({ channel => 'sandbox2', # optional, if not applied, the one in ->new will be used. messages => ['message3', 'message4'] }); # subscribe $pubnub->subscribe({ callback => sub { my (@messages) = @_; foreach my $msg (@messages) { print "# Got message: $msg\n"; } return 1; # 1 to continue, 0 to stop } }); # DESCRIPTION PubNub::PubSub is Perl library for rapid publishing of messages on PubNub.com based on [Mojo::UserAgent](https://metacpan.org/pod/Mojo::UserAgent) perl clone of [https://gist.github.com/stephenlb/9496723#pubnub-http-pipelining](https://gist.github.com/stephenlb/9496723#pubnub-http-pipelining) For a rough test: - run perl examples/subscribe.pl in one terminal (or luanch may terminals with subscribe.pl) - run perl examples/publish.pl in another terminal (you'll see all subscribe terminals will get messages.) # METHOD ## new - pub\_key optional, default pub\_key for publish - sub\_key optional, default sub\_key for all methods - channel optional, default channel for all methods - publish\_callback optional. default callback for publish - debug set ENV MOJO\_USERAGENT\_DEBUG to debug ## subscribe subscribe channel to listen for the messages. $pubnub->subscribe({ callback => sub { my (@messages) = @_; foreach my $msg (@messages) { print "# Got message: $msg\n"; } return 1; # 1 to continue, 0 to stop } }); return 0 to stop ## publish publish messages to channel $pubnub->publish({ messages => ['message1', 'message2'], callback => sub { my ($res) = @_; # $res is a L say $res->code; # 200 say Dumper(\$res->json); # [1,"Sent","14108733777591385"] } }); $pubnub->publish({ channel => 'sandbox2', # optional, if not applied, the one in ->new will be used. messages => ['message3', 'message4'] }); Note if you need shared callback, please pass it when do ->new with **publish\_callback**. new Parameters specifically for **Publish V2 ONLY** - ortt - Origination TimeToken where "r" = DOMAIN and "t" = TIMETOKEN - meta - any JSON payload - intended as a safe and unencrypted payload - ear - Eat At Read (read once) - seqn - Sequence Number - for Guaranteed Delivery/Ordering We'll first try to read from **messages**, if not specified, fall back to the same level as messages. eg: $pubnub->publish({ messages => [ { message => 'test message.', ortt => { "r" => 13, "t" => "13978641831137500" }, meta => { "stuff" => [] }, ear => 'True', seqn => 12345, }, { ... } ] }); ## if you have common part, you can specified as the same level as messages $pubnub->publish({ messages => [ { message => 'test message.', ortt => { "r" => 13, "t" => "13978641831137500" }, seqn => 12345, }, { ... } ], meta => { "stuff" => [] }, ear => 'True', }); ## history fetches historical messages of a channel - sub\_key optional, default will use the one passed to ->new - channel optional, default will use the one passed to ->new - count Specifies the number of historical messages to return. The Default is 100. - reverse Setting to true will traverse the time line in reverse starting with the newest message first. Default is false. If both start and end arguments are provided, reverse is ignored and messages are returned starting with the newest message. - start Time token delimiting the start of time slice (exclusive) to pull messages from. - end Time token delimiting the end of time slice (inclusive) to pull messages from. Sample code: my $history = $pubnub->history({ count => 20, reverse => "false" }); # $history is [["message1", "message2", ... ],"Start Time Token","End Time Token"] for example, to fetch all the rows in history my $history = $pubnub->history({ reverse => "true", }); while (1) { print Dumper(\$history); last unless @{$history->[0]}; # no messages sleep 1; $history = $pubnub->history({ reverse => "true", start => $history->[2] }); } # GITHUB [https://github.com/binary-com/perl-pubnub-pubsub](https://github.com/binary-com/perl-pubnub-pubsub) # AUTHOR Binary.com # LICENSE AND COPYRIGHT Copyright 2014- binary.com.
