Is there anyway to filter list_views() by workspace? Or to list all views only on a certain workspace?

I assume that this has to be accessible externally somehow because the switcher plugin is able to access it, but I'm not fluent enough in c++ to really understand how it does that, or if I could do that over IPC. Thank you for any help! I've been stuck on this for a minute and I will really appreciate any guidance

Hi, there is no magic way to compute workspaces for views. Workspaces are arranged in a grid and views can freely move between them, overlapping multiple workspaces, which is why there isn't really a single "workspace" assigned to a view. Most of the time, we use a heuristic. Compute the center point of a view, and divide it by the output resolution. As view geometry is relative to the current workspace, this would give you a rough idea on which workspace the view is, relative to the current one. Small example:

• 3x3 workspace grid, currently on workspace 1,1 (the center as indexing starts from 0)
• Output has size 1920x1080
• A view has its center point at -640, 1090
• -640/1920 = -0.333, flooring gives -1
• 1090/1080 is a bit over 1
• All in all, we can conclude view is on workspace 1+(-1)=0, so first column, and 1+1=2, so third row.

Hope this makes sense.

ohhhh I don't know how I didn't notice that last night haha. Rewording in case anyone is confused by this in the future, for my case I have a 3440x1440 display, with 3 terminals open, one on workspaces 1,0 running my editor, one on 1,1 running this experiment, and one on 1,2 running btop. I have a python script that includes:

sock = WayfireSocket()

views = []

for v in sock.list_views():
  if v["app-id"] == "kitty":
    views.append(v)

print(json.dumps(views, indent = 2))

when I run this script from the terminal on 1,1 I see my terminal running btop has a y coordinate of 1458, below my current workspace, and my terminal running an editor has a negative y coordinate placing it above my current workspace.

So if for example I want to filter for views that are entirely within the active workspace I would want to do something like

sock = WayfireSocket()

views = []

for v in sock.list_views():
  if v["geometry"]["x"] >= 0 and v["geometry"]["x"] and (v["geometry"]["x"] + v["geometry"]["width"]) <= 3440 and (v["geometry"]["y"] + v["geometry"]["height"]) <= 1440:
    views.append(v)

print(json.dumps(views, indent = 2))

thanks for the help!

Hi, This works only for the focused (output) wset-index, for multi output you need to improve to catch all wsets

from wayfire import WayfireSocket
from wayfire.extra.ipc_utils import WayfireUtils as Utils

sock = WayfireSocket()
utils = Utils(sock)

output_info = sock.get_focused_output()

o_id = output_info["id"]
o_name = output_info["name"]
ws_cfg = output_info["workspace"]

print(f"=== Output: {o_name} ===")

for ty in range(ws_cfg["grid_height"]):
    for tx in range(ws_cfg["grid_width"]):
        views = utils.list_filtered_views()
        v_in_ws = []
        
        for i in views:
            if i.get("output-id") != o_id:
                continue

            ws = utils.get_workspace_from_view(i["id"])
            if ws and ws["x"] == tx and ws["y"] == ty:
                v_in_ws.append(i)

        if v_in_ws:
            print(f"  Workspace ({tx}, {ty}):")
            for v in v_in_ws:
                print(f"    - [{v['id']}] {v.get('app-id')}: {v.get('title')}")

you can also use utils.get_views_from_active_workspace() to get views from active workspace
