Hi all,

I often find myself using python scripts that generate a lot of graphs. I'd like to create a script that will count the number of graphs in a workspace and then line them up in a grid - ie if 6 are plotted, arange them all in a 2x3 grid. I know I am going to have to script this - no problem, but the first thing I need to figure out is how to programtically cycle through all the windows in a workspace. I know how to use xprop to get the window type, but I can't seem to find something like (pseudo code):

for window in workspce; goto window; ...

of course, after goto window, you can get the type and keep track of things, etc. Just need to get started. Any help is appreciated!

wmctrl -l can list the windows starting with the window id which can be fed to xprop. There are also convenient libraries to use to interact with your shell easier

That said you might want something more i3 oriented as you it sounds like you want the windows in your workspace not all that match a criteria as you may someday have more than one workspace with matching windows.

In theory you could get all you need from i3-msg -t get_tree and use jq to process the resulting json but since you mentioned python you probably want

Thanks! I will try that. Of course, this is a "Gee-job" at work, so it might take me a little time to figure it all out, but you pointed me to some useful stuff, so I am going to give you credit for the answer :) Thanks!
