So this is to bring the alttab behavior to sway. Just put the alttab file in your ~/.config/sway/alttab file.
Run chmod +x ~/.config/sway/alttab.
and add the provided the provided bindsym in your sway config file.

PS: I am pretty certain that this should work with i3 as well.

Hi, thanks for this script. I was looking for this functionality for a long time.
I found some cases it doesn't work, so I consider to share you some fixes I made. Thanks

#!/usr/bin/env python3

import sys
import json
import subprocess

direction=bool(sys.argv[1] == 'next')
swaymsg = subprocess.run(['swaymsg', '-t', 'get_tree'], stdout=subprocess.PIPE)
data = json.loads(swaymsg.stdout)
current = data["nodes"][1]["current_workspace"]

for i in range(len(data["nodes"][1]["nodes"])):
    if data["nodes"][1]["nodes"][i]["name"] == current :
        workspace = i
        break

roi = data["nodes"][1]["nodes"][workspace]
temp = roi
windows = list()

def getNextWindow():

    if focus < len(windows) - 1:
        return focus+1
    else:
        return 0

def getPrevWindow():

    if focus > 0:
        return focus-1
    else:
        return len(windows)-1

def makelist(temp):

    for i in range(len(temp["nodes"])):
        if temp["nodes"][i]["name"] is None:
           makelist(temp["nodes"][i])
        else:
           windows.append(temp["nodes"][i])

def focused(temp_win):

    for i in range(len(temp_win)):
        if temp_win[i]["focused"] == True:
           return i
    
    return 9;

makelist(temp)
focus = focused(windows)

if direction:
    attr = "[con_id="+str(windows[getNextWindow()]["id"])+"]"
else:
    attr = "[con_id="+str(windows[getPrevWindow()]["id"])+"]"

sway = subprocess.run(['swaymsg', attr, 'focus'])
sys.exit(sway.returncode)

And on sway config

bindsym Mod1+tab exec ~/.config/sway/alttab next
bindsym Mod1+shift+tab exec ~/.config/sway/alttab prev

Thanks again. Have a nice day,
Alejandro

I struggled by sometimes when it doesn't work but that was because I use zsh and it parses [ ] on a 'special' way... so I reworked the way it launches swaymsg in that debug process. I also found that script doesn't work when workspaces aren't continuous, I mean, not 1,2,3,4,5,6,7 but like only 2,5,7 workspaces active. In this case your script don't switch the focus. Thanks,

I will look into these issues soon enough. if you are facing zsh issues i would suggest using bash -c in your exec command. Thank you for your suggestions, i will merge them once i figure out the issues you are facing and why. .

gorsheninmv · 2020-02-13T17:29:07Z

Hi guys! Your implementations don`t work with floating windows. I`m quite newbie in python so that my desicion isn`t perfect. But I would like to share it with you. I just modified makelist function. Hope it helps you:

def makelist(temp):

    for nodes in "floating_nodes", "nodes":
        for i in range(len(temp[nodes])):
            if temp[nodes][i]["name"] is None:
               makelist(temp[nodes][i])
            else:
               windows.append(temp[nodes][i])

Thanks for the script!

alejor · 2020-02-13T19:02:46Z

Great improvement, gorsheninmv, thanks :)

SidharthArya · 2020-02-20T18:16:29Z

@gorsheninmv , thank you for the improvement.

curiositry · 2020-05-15T02:24:52Z

I have been successfully using @alejor's version for a while. Now, after an update to sway I believe, it is giving an error for line 11:

Traceback (most recent call last):
  File "/home/[user]/.config/sway/alttab", line 11, in <module>
    current = data["nodes"][1]["current_workspace"]
KeyError: 'nodes'

SidharthArya · 2020-05-15T06:29:53Z

@curiositry, @alejor 's version work fine. I have just tested both. Feel free to post again if it doesn't work.

alejor · 2020-05-15T15:34:24Z

@curiositry, I just updated my sway to latest commit and still it works fine. So we would know more details to give you any advice, :)

curiositry · 2020-05-16T02:16:22Z

Thanks for your replies @SidharthArya and @alejor. I have updated to @SidharthArya's latest version, and it is now working. (Curiously, it didn't work until I rebooted; reloading Sway didn't suffice.)

SidharthArya · 2020-05-16T03:25:39Z

@curiositry Glad to hear it worked.

And here is an extension for a multi-monitor aware win+tab to flip workspaces open on a monitor:

RayZ0rr · 2022-04-27T20:57:32Z

Will this work in i3?

josch · 2022-12-17T06:22:51Z

There is quite some room for simplification by using the i3ipc python module:

#!/usr/bin/env python3
import i3ipc
import sys
def main():
    sway = i3ipc.Connection()
    for workspace in [ws for output in sway.get_tree().nodes for ws in output.nodes]:
        focus = workspace.find_focused()
        if focus is None:
            continue
        descendants = [d for d in workspace.descendants() if d.name is not None]
        focus = descendants.index(focus)
        focus = (focus + 1 if sys.argv[1] == "next" else focus - 1) % len(descendants)
        sway.command(f"[con_id={descendants[focus].id}] focus")
        sys.exit()
if __name__ == '__main__':
    main()

aloispichler · 2023-11-17T22:50:32Z

Does it work on hyprland as well?
