getting app-id on cosmic

[bashfulrobot]

Has anyone come up with a good way to get the app-id/class from a running window on Cosmic? All the tools that appear in a search are desktop-specific.

Cheers.

You can do that via a client that uses the ext-foreign-toplevel-list protocol: https://wayland.app/protocols/ext-foreign-toplevel-list-v1

There is an example cli client in our protocol repo for the (now outdated) cosmic-toplevel protocol (which was very similar): https://github.com/pop-os/cosmic-protocols/blob/main/examples/toplevel-list.rs

More code can be found in e.g. the cosmic-applets, the cosmic-launcher plugin or cosmic-workspaces.

one such client that you would be looking for could be lswt.

Run lswt to get a list of appids and titles.

@badlydrawnface funny, I came upon that one about 2 weeks ago, and had installed exactly that! It's great for this use case.
