=head1 NAME

AnyEvent::I3 - communicate with the i3 window manager

=cut

our $VERSION = '0.19';

=head1 VERSION

Version 0.19

=head1 SYNOPSIS

This module connects to the i3 window manager using the UNIX socket based
IPC interface it provides (if enabled in the configuration file). You can
then subscribe to events or send messages and receive their replies.

    use AnyEvent::I3 qw(:all);

    my $i3 = i3();

    $i3->connect->recv or die "Error connecting";
    say "Connected to i3";

    my $workspaces = $i3->message(TYPE_GET_WORKSPACES)->recv;
    say "Currently, you use " . @{$workspaces} . " workspaces";

...or, using the sugar methods:

    use AnyEvent::I3;

    my $workspaces = i3->get_workspaces->recv;
    say "Currently, you use " . @{$workspaces} . " workspaces";

A somewhat more involved example which dumps the i3 layout tree whenever there
is a workspace event:

    use Data::Dumper;
    use AnyEvent;
    use AnyEvent::I3;

    my $i3 = i3();

    $i3->connect->recv or die "Error connecting to i3";

    $i3->subscribe({
        workspace => sub {
            $i3->get_tree->cb(sub {
                my ($tree) = @_;
                say "tree: " . Dumper($tree);
            });
        }
    })->recv->{success} or die "Error subscribing to events";

    AE::cv->recv

=head1 EXPORT

=head2 $i3 = i3([ $path ]);

Creates a new C<AnyEvent::I3> object and returns it.

C<path> is an optional path of the UNIX socket to connect to. It is strongly
advised to NOT specify this unless you're absolutely sure you need it.
C<AnyEvent::I3> will automatically figure it out by querying the running i3
instance on the current DISPLAY which is almost always what you want.
