.SH NAME
AnyEvent::Impl::Irssi \- AnyEvent adaptor for Irssi
.SH SYNOPSIS
.IX Header "SYNOPSIS"
.Vb 1
\&   use AnyEvent;
\&  
\&   # this module gets loaded automatically when running under irssi
.Ve
.SH DESCRIPTION
.IX Header "DESCRIPTION"
This module provides transparent support for AnyEvent. You don\*(Aqt have to
do anything to make Irssi scripts work with AnyEvent.
.PP
Limitations of this backend and implementation details:
.IP \(bu 4
This backend does not support blocking waits.
.Sp
That means you must set a callback on any condvars, or otherwise make sure
to never call \f(CW\*(C`recv\*(C'\fR on a condvar that hasn\*(Aqt been signalled yet.
.IP \(bu 4
Child exits will be handled by AnyEvent.
.Sp
AnyEvent will take over child handling, as Irssi only polls for children
once/second and cannot handle unspecific child watchers.
.Sp
This \fIshould\fR have no negative effect, as AnyEvent will emit a pidwait
signal just like irssi itself would.
.IP \(bu 4
Artificial timer delays.
.Sp
Irssi artificially enforces timers to have at least a 10ms delay (by
croaking, even).
.Sp
This means that some applications will be limited to a rate of 100Hz (for
example, Coro::AnyEvent thread scheduling).
.IP \(bu 4
Irssi leaks memory like hell.
.Sp
Yeah.
.PP
Apart from that, documentation is notoriously wrong (e.g. file handles
are not supported by \f(CW\*(C`input_add\*(C'\fR, contrary to documentation), hooking
into irssi has to be done in... weird... ways, but otherwise, Irssi is
surprisingly full\-featured (for basically being a hack).
