Hi,

I am having problems scripting the window-manager i3 with perl using AnyEvent::I3 and as I could not get any help in an i3-forum, I try my luck here...

This works:

use strict;
use AnyEvent;
use AnyEvent::I3;

my $i3 = i3();

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

$i3->command("workspace 1")->recv;
[download]

Running this changes to workspace 1.

And this also works:

use strict;
use AnyEvent;
use AnyEvent::I3;

my $i3 = i3();

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

$i3->subscribe({
                workspace => \&handle
              })->recv->{success} or die "Error subscribing to events"
+;

AE::cv->recv;


sub handle {
  my($data)=@_;

  if($data->{change} eq "empty") {
    print "empty workspace!!\n";
  }
}
[download]

Running this prints "empty workspace!!" whenever a workspace become empty.

What I want now is to combine the logic, so whenever a workspace becomes empty we change to workspace 1.

Here is my attempt:

use strict;
use AnyEvent;
use AnyEvent::I3;

my $i3 = i3();

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

$i3->subscribe({
                workspace => \&handle
              })->recv->{success} or die "Error subscribing to events"
+;

AE::cv->recv;


sub handle {
  my($data)=@_;

  if($data->{change} eq "empty") {
    print "empty workspace!!\n";
    $i3->command("workspace 1")->recv;
  }
}
[download]

However this does not work. It prints "empty workspace!!" ok, but it does not send the command, the error is:

EV: error in callback (ignoring): AnyEvent::CondVar: recursive blockin
+g wait attempted
[download]

Any ideas?

Many thanks!
