Sorry the screencast is not clear. I wrote a shell script to check how it works this time. (You don't have to check it)

The -L is working as expected "unconditionally alternating between target and ORIGIN".

As I was working on this shell script, I noticed that they all had the expected "unconditionally alternate between target and ORIGIN" behavior this time when auto_nop_delay = 200 was enabled.

However, when I use -L, I don't have to consider whether the switching interval is less than auto_nop_delay or not, and the result is always the same, which is more convenient for me.

I will continue to check these behaviors as I use it.

Thanks for your kind implementation.

In the following, LRU seems to be included in the switch destination. How can I switch only between MARK and ORIGIN?

swayr switch-to-mark-or-urgent-or-lru-window --skip-lru-if-current-doesnt-match               MARK || foot --app-id='APP'
swayr switch-to-mark-or-urgent-or-lru-window --skip-lru-if-current-doesnt-match --skip-origin MARK || foot --app-id='APP'

Thanks. I tested the following.

$ pacman -Q swayr-git
swayr-git r431.ec73a59-1
$

test.conf

for_window [app_id="APP"] mark "MARK"

set $mode_test "Test6[*]?"
mode $mode_test {

    bindsym a exec swayr switch-to-mark-or-urgent-or-lru-window      --skip-lru-if-current-doesnt-match --skip-lru MARK                || foot --app-id='APP'

    bindsym c exec swayr switch-to-app-or-urgent-or-lru-window       --skip-lru-if-current-doesnt-match --skip-lru APP                 || foot --app-id='APP'
    bindsym d exec swayr switch-to-app-or-urgent-or-lru-window       -L                                 --skip-lru APP                 || foot --app-id='APP'
    bindsym e exec swayr switch-to-matching-or-urgent-or-lru-window  --skip-lru-if-current-doesnt-match --skip-lru '[con_mark="MARK"]' || foot --app-id='APP'
    bindsym f exec swayr switch-to-matching-or-urgent-or-lru-window  -L                                 --skip-lru '[app_name="APP"]'  || foot --app-id='APP'
    bindsym g exec swayr switch-to-matching-or-urgent-or-lru-window  -L                                 --skip-lru '[app_id="APP"]'    || foot --app-id='APP'

    bindsym z exec foot --app-id='APP'
    # back to normal: Escape
    bindsym Escape mode "default"
}
bindsym $mod+t mode $mode_test

It seems that if I do a,b,e when MARK has focus, I can't switch.

Sorry if I misunderstood something.

I think the current behavior is correct for swayr's specification, but when I want to switch unconditionally and alternately between a target for which the user has specified app_id and mark, and the window that has the previous focus, I have to make the script do the following conditional branching.

e.g. If the target is focused, swayr switch-to-urgent-or-lru-window is executed. Otherwise, execute swayr switch-to-app-or-urgent-or-lru-window $app_id_or_class --skip-lru --skip-origin.

That may not be a problem, but it seems a bit frustrating not to be able to use that usage by default.

What is the lockin_delay,auto_nop_delay,seq_inhibit in your config? My ~/.config/swayr/config.toml is below in default state.

[focus]
lockin_delay = 750

[misc]
seq_inhibit = false

https://streamable.com/y11shc

I think so.

$ pacman -Q swayr-git
swayr-git r427.6c56b3f-1
$

When there are three different windows - mark, current, and one previous focus - I want only mark and current to switch repeatedly.

Sorry if I didn't communicate it well. I would like something that satisfies the following

• When the current window is MARK-foot, I want to switch alternately between only a single LRU (one previously focused window) and only MARK-foot.
• When the current window is not MARK-foot, I want to switch alternately between only MARK-foot and the only current window.

Thanks, I have run Test1-4.

$ pacman -Q swayr-git
swayr-git r427.6c56b3f-1
$

It may be a problem with my usage, but I was curious about something.

Here is what I want to do: "I want to be able to switch alternately between the window to be marked at any time and the window that is currently or one focus ago."

With the following settings, a,b will cause the LRU to intervene between origin and the mark target. It seems that c cannot switch anywhere because the mark target is origin.

screencast: https://streamable.com/0hm3tb

for_window [app_id="MARK"] mark "MARK"

set $mode_test "Test5[*]?"
mode $mode_test {

    bindsym a exec swayr switch-to-mark-or-urgent-or-lru-window --skip-origin MARK  || foot --app-id='MARK'
    bindsym b exec swayr switch-to-mark-or-urgent-or-lru-window               MARK  || foot --app-id='MARK'
    bindsym c exec swayr switch-to-mark-or-urgent-or-lru-window --skip-lru    MARK  || foot --app-id='MARK'

    # back to normal: Escape
    bindsym Escape mode "default"
}
bindsym $mod+t mode $mode_test

Is there any way to fix this?

I probably found a case where there is a target but non-zero exit. I think this should be a 0 exit because the target exists.
