I installed all the dependencies stated at the docmentation , then tried compiling the application but i was prompted with this error

@z0xyz I just got the same error. Are you trying to compile this on elementary OS 6 (Odin)?

@markstory Do you know which dependency meta/screen.h is from? I found a screen.c in Mutter (which is where all the Meta stuff is from, I think) and it has a screen-private.h. (Was wondering if they made it private in a more recent version or something.) Not sure if I’m even looking in the right place though. The joys of not knowing the frameworks and having a coffeescript-style transformation step in the middle thanks to Vala. sigh Not exactly the sort of thing you can just jump into :)

[aral]

It’s possible that this is the same issue as: elementary/gala#303

Also see: https://gist.github.com/Tireg/dcb264f755d4e83de53f44a4032a9598

(It looks like Meta.Screen was renamed to Meta.Display.)

Also possibly related: solus-project/budgie-desktop#1591

Also: https://gist.github.com/Tireg/f4c6e28258601dedb73aca517d322806

Looks like there were a metric you-know-what tonne of breaking changes in Mutter 3.30 and I can’t seem to find them documented anywhere apart from people’s patches.

I don't know the providence of that header file. This repo started off using the code from another project and that dependency was inherited. Those other issues due seem related, but my Vala knowledge is also very low.

Thanks @markstory. I’m going to keep looking into it as elementary OS is basically unusable for me with the stock task switcher.

@markstory OK, I’ve got it running on Odin but it’s Odin only. I don’t have time right now to also make it work in Hera. I’m thinking of releasing a fork that’s Odin-only and linking here for folks who are on Hera if that’s OK with you. (I also plan on trying to get the elementary OS folks to make it the default task switcher going forward.) And, of course, please feel free to work the updates back here and have a plugin that runs on both.

That is fine. Once your fork is up, I'll update the README here to point folks towards your Odin fork.

@markstory Hey Mark, Catts (Calmer Alt-Tab Task Switcher) is live!

https://github.com/small-tech/catts

(And there is a free wallpaper to download too, if you like.) :)

Also, I’ve opened a feature request on the elementary OS Gala issue tracker to hopefully get it included in elementary OS in place of the stock task switcher. If you or anyone else here would like to give that a thumbs up, I’d appreciate it :)

Lots of love + thank you for Gala Alt-Tab Plus without which Catts wouldn’t exist.

@aral sorry for the very late reply , but i hadn't check the repo after scouring the web for an alternative .

Are you trying to compile this on elementary OS 6 (Odin)?

yes, i was building it on elementary odin right after i installed it .

Hey Mark, Catts (Calmer Alt-Tab Task Switcher) is live!

i've tried to install your fork instead of gala-switch , aiming for the previous feature of this repo which was its capability of switching between the windows of the same application , but unfortunately gala continue using the aforementioned one .
edit:
i had to uninstall the previous one with ninja -C build uninstall first , before executing gala --replace &
