Filterway

is a lightweight Wayland socket proxy that intercepts messages and filters/modifies them. You can use it for, for example, making all applications in a container have the same app_id (apply certain window decorations in certain containers).

Current features:

• Force app_id - assign all toplevels the same app_id and suppress client-originated set_app_id requests
• Dump wayland protocol traffic

How to use it

Your main compositor will have created something like /run/user/1000/wayland-0 where 1000 is your user ID.

1. Build filterway with cargo build
2. Run filterway /run/user/1000/wayland-0 /run/user/1000/wayland-filtered org.example.testid
3. Run Wayland applications or another compositor with WAYLAND_DISPLAY=wayland-filtered
