How to show/hide dock programatically instead of toggling?

[karamanliev]

I made a script to show the dock when there are no windows after workspace change and to make it in -d (autohide) mode when there are windows on the workspace.

Unfortunately I can't find a way to do it currently because I can't find a way to do it, because there is an option only to toggle it.

Also, is it possible to show the dock on every monitor? I tried launching multiple instances but it didn't work.

Am I missing something?

You are right. We have no way to turn on/off specifically, just USR1 to toggle.

[karamanliev]

I treid to implement an "intelligent" dock, using hyprland's IPC socket in bash. It kind of works, but it's getting complex, because of no real on/off state. Now I have to do it for multiple monitors & workspaces with floating windows only 🤣

A future update to have this feature will be very appreciated. I haven't used Go, but I might try to do a PR if I have some more free time. Thanks for the great software!

[nwg-piotr]

The hardest part is to decide which signals to use for show and hide, as we need to leave USR1 as is, to avoid breaking users' configs. The code itself would be easy.

[karamanliev]

I currently implemented it for workspace, openwindow, closewindow, activespecial and focusedmon, but there might be more like changefloatingmode and movewindow.

[nwg-piotr]

Maybe, instead of external scripting, it would make sense to add such behaviour as a dock option?

[karamanliev]

Oh, it would be awesome!

[nwg-piotr]

Make a list which event should trigger which action, e.g.:

openwindow - hide
closewindow - show
(...)

and so on, and I'll try to do so.

[karamanliev]

I'm not sure if it would be that simple. In my opinion, active workspace window count and maybe window positions should be tracked on different signals. And then, depending on the result the dock should be hidden or shown.

[nwg-piotr]

Well, maybe it makes more sense to leave it for an external script. I can imagine dozen of issues submitted by people who want stuff to work differently.

[karamanliev]

Yeah, you're right. Just a simple nwg-dock-hyprland --show / nwg-dock-hyprland --hide switch would suffice. This would not disrupt the current toggle behaviour.

A bonus would be, if it's possible to add something like --show -o monitorID to force showing on a specified display. This currently works with -d. The dock shows on the display where you hover the hotspot.

[nwg-piotr]

I'll stick to signals. In addition to the current USR1 for Toggle, I'll make:

• SIGRTMIN+1 for Toggle (USR1 will be deprecated from now on),
• SIGRTMIN+2 for Show,
• SIGRTMIN+3 for Hide.

Basic code is ready.

A bonus would be (...)

This would be difficult, if even possible.

[nwg-piotr]

@karamanliev Would you mind sharing your script, when adjusted to the latest changes? We could add it to the repo.

[maarutan]

I can't wait to see your script ;))))

[karamanliev]

Basically works perfect on a single monitor with -d and -r and on multiple monitors with -r. If anyone has any ideas how to make it work, please do. I think the process should be killed and started again and something like a debounce ot throttle should be added so it doesn't run multiple times if switching very fast between monitors. I'm not good at bash 🤣

Maybe I will just create a custom hotspot for myself that just toggles the dock on mouse enter / mouse leave.

There's also no event to track when a window has ended moving or something to be able to hide it if you move a floating window with mouse.

I've only tested with dock on bottom, but I guess it'll be almost the same on the sides/top. Instead window X size and pos should be tracked and maybe the free_space calculation should change a bit.

Hacky, but it does the job. Multi monitor "intelligent" dock on active screen works perfect this way. I'd really like it if there was a native way to do it from nwg-dock-hyprland.

Pay attention to the fact, that you are unable to run multiple instances of the program. Depending on the arguments in use, it'll behave differently, but 2 instances should be impossible in any case.

Yep, it almost worked when relaunching with pkill -f nwg-dock-hyprland when switching between monitors, but it was not perfect. I'll revisit it tomorrow, when I have some free time.

[maarutan]

The script doesn't work for me, can you tell me in detail how to run it?

[karamanliev]

just chmod +x path/to/script.sh, then exec-once = path/to/script.sh in your hyprland config.

Also check the INITIAL_LAUNCH_FLAGS and change them accordingly to suit your needs.

Try to run it in your terminal first. And tell me if you're getting any errors.

At the same time, autoHide does not work for me when aiming at a hot spot

Change -r with -d for autohide

[maarutan]

I already have it at -d

lol, remove -notooltips. I forked the repo and built a binary for myself with it.

Sorry, my bad, forgot to remove it from the script.

[maarutan]

lol thanks for the script ^^

I'm sorry, but how did you style the application launcher???

my app launcher is orange i want to change it to white or purple

It's in the README. Use -ico and provide path for your own icon.
