I normally use zsh but I tried it both for zsh and bash and got the same error...

The output I got:

DP-2:1:1:
DP-4:3:3:

I used icons in my ws names, which is not displaying on GitHub, bu shows like this for me.

Maybe that's the issue? Also somehow my only two monitors are named DP-2 and DP-4...

I meant what shell /bin/sh points to you can see which it is with realpath /bin/sh

yeah thats the issue

Can you reference them by there number, for example does this put focus on your chrome workspace ?
i3-msg -- workspace --no-auto-back-and-forth "1"

If yes then just change screen, workspace = l.strip().split(':') to screen, workspace = l.strip().split(':')[:2]

If it works then I will add it to the gist.

Let me see. The original script this is forked from did not give me that error.

@Zackhardtoname it should work now ! thanks for your feedback, I keep my workspaces named with numbers so I never ran into this issue.
The problem here was that you have : in your workspace name and that's the symbol I use to split.

That wouldn't and didn't work because somehow i3 treats ws "3" and "3:" differently.
This works: screen, workspace = l.strip().split(':', maxsplit=1)

Thank you so much! I should have dug this more myself

Hi
I grabbed your script thinking that it would manage my special naming convention

set $workspace1 "1 "
set $workspace2 "2 "
set $workspace3 "3 "
set $workspace4 "4 "
set $workspace5 "5 "
set $workspace6 "6 "
set $workspace7 "7 "
set $workspace8 "8 "
set $workspace9 "9 "
set $workspace10 "10 "

Unfortunately, it doesn't, because of the spaces. Had to change the names changing spaces with underscores.
Not as pretty but it works.

Do you think there's a way to handle spaces in workspaces names ?

Regards

I just wanted to say thank you: I can't imagine how long it would have taken me to figure this out.
