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
"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. "AnyEvent::I3" will automatically figure it out by querying the running i3 instance on the current DISPLAY which is almost always what you want.

if ($i3->connect->recv) { say "Connected to i3"; }
my %callbacks = ( workspace => sub { say "Workspaces changed" } ); if ($i3->subscribe(\%callbacks)->recv->{success}) { say "Successfully subscribed"; }
The special callback with name "_error" is called when the connection to i3 is killed (because of a crash, exit or restart of i3 most likely). You can use it to print an appropriate message and exit cleanly or to try to reconnect.
my %callbacks = ( _error => sub { my ($msg) = @_; say "I am sorry. I am so sorry: $msg"; exit 1; } ); $i3->subscribe(\%callbacks)->recv;
my $reply = $i3->message(TYPE_COMMAND, "reload")->recv; if ($reply->{success}) { say "Configuration successfully reloaded"; }
my $ws = i3->get_workspaces->recv; say Dumper($ws);
my $outs = i3->get_outputs->recv; say Dumper($outs);
my $tree = i3->get_tree->recv; say Dumper($tree);
my $marks = i3->get_marks->recv; say Dumper($marks);
my $config = i3->get_bar_config($id)->recv; say Dumper($config);
my $version = i3->get_version()->recv; say "major: " . $version->{major} . ", minor = " . $version->{minor};
my $reply = i3->command("reload")->recv; die "command failed" unless $reply->{success};
