dwl is a compact, hackable compositor for Wayland based on [wlroots](https://github.com/swaywm/wlroots). It is intended to fill the same space in the Wayland world that dwm does in X11, primarily in terms of philosophy, and secondarily in terms of functionality. Like dwm, dwl is:
dwl is a compact, hackable compositor for Wayland based on [wlroots](https://gitlab.freedesktop.org/wlroots/wlroots/). It is intended to fill the same space in the Wayland world that dwm does in X11, primarily in terms of philosophy, and secondarily in terms of functionality. Like dwm, dwl is:

- Easy to understand, hack on, and extend with patches
- One C source file (or a very small number) configurable via `config.h`
