Cage: a Wayland kiosk

This is Cage, a Wayland kiosk. A kiosk runs a single, maximized application.

User input such as moving, resizing, minimizing and unmaximizing windows is ignored. Dialogs are supported, although they too cannot be resized nor moved. Instead, dialogs are simply centered on the screen. There is no configuration for Cage. When the application is closed, Cage closes as well.

Cage supports a single, static output. It does not support hotplugging nor rotation. Input-wise, Cage supports pointer input, keyboard input and (soon) touch input. Copy and paste works as well.

Cage does not support Xwayland, nor any protocols other than xdg-shell. That is, there is no support for panels, virtual keyboards, screen capture, primary selection, etc. Open a PR if you want to see support for some of these; they can likely be added without much work. Cage fulfills my needs in its current state.

Notable omissions from Cage, to be added in a future version:

Damage tracking, which tracks which parts of the screen are changing and minimizes redraws accordingly.
HiDPI support.

Building and running Cage

You can build Cage by simply running make. It requires wayland, wlroots and xkbcommon to be installed.

You can run Cage by running ./cage APPLICATION. If you run it from within an existing X11 or Wayland session, wlroots will open a virtual output as a window in your existing session. If you run it at a TTY, it'll run with the KMS+DRM backend. In debug mode (make debug), press Alt+Esc to quit.

Cage is based on the annotated source of TinyWL.
