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.

   Note, socket ancillary data (required by Wayland protocol) requires unstable rust currently. If you use rustup to manage rust it should read the rust-toolchain.toml file and compile accordingly.

2. Run filterway /run/user/1000/wayland-0 /run/user/1000/wayland-filtered org.example.testid

   Run filterway --help for details.

3. Run Wayland applications or another compositor with WAYLAND_DISPLAY=wayland-filtered
