IPC::Messaging - process handling and message passing, Erlang style
This document describes IPC::Messaging version 0.01_14.
use IPC::Messaging; # Process creation my $proc = spawn { receive { got ping => then { print "$$: got ping from $_\n"; $_->pong; }; }; }; # Message sending $proc->ping; # Message matching receive { # matching message name got somemsg => then { }; # matching message name and sender got pong => $proc => then { }; # matching message name and content got msg => x => 1 => then { }; # matching with a custom filter got msg => \&is_something => then { }; # matching any message got _ => then { my ($message, $message_data, $from) = @_; print "$$: got $message from $from\n"; # $_ is the same as $from: print "$$: got $_[0] from $_\n"; }; after 2 => then { print "$$: timeout\n"; }; }; # TCP via message matching IPC::Messaging->tcp_server(1111); while (1) { receive { got tcp_connect => then { print "connect from $_[1]->{from}\n"; print $_ "hi\n"; }; got tcp_data => then { print "got data: $_[1]->{data}\n"; }; got tcp_disconnect => then { print "disconnect from $_[1]->{from}\n"; }; }; }
This is a preliminary development version, and as such it is extremely poorly documented.
Perl 5.8.4 or above, B::Generate, Module::Load::Conditional.
This module, in all likelihood, will only work on Unix-like operating systems.
No bugs known. The API is a moving target. To be useful, reads from sockets in form of messages must be supported to a greater degree than they are now.
