This is my second “I feel like a complete idiot” question of the week, so thank you for your patience.
How does one find an app-id, e.g., for setting up window rules in my window manager (River)? For example, if I’m using Nautilus as a file manager and I wanted to have the Nautilus Previewer window float by defining a River WM rule, I can do every bit of that trivially, other than identifying the app-id. (In this case, I believe it’s org.gnome.NautilusPreviewer, but I’m looking for a general case.) Please note this question is about Wayland and not X.
I dropped into GNOME and viewed active windows with Looking Glass (lg), but that seems like a silly workflow just to ID a window.
Okay but I am not going to make something where I have to read the sourcecode in order to get any info. Thanks anyway.
You don’t have to read the source code. You just clone the repo and run make to install it. Then just run the
lswtcommand which will show youapp-ids of any running apps.
