# dwl
|
|
|
|
This is the "minimum viable product" Wayland compositor based on wlroots. It
|
|
aims to implement a Wayland compositor in the fewest lines of code possible,
|
|
while still supporting a reasonable set of features. Reading this code is the
|
|
best starting point for anyone looking to build their own Wayland compositor
|
|
based on wlroots.
|
|
|
|
|
|
## Building dwl
|
|
|
|
dwl is disconnected from the main wlroots build system, in order to make it
|
|
easier to understand the build requirements for your own Wayland compositors.
|
|
Simply install the dependencies:
|
|
|
|
- wlroots
|
|
- wayland-protocols
|
|
|
|
And run `make`.
|
|
|
|
|
|
## Running dwl
|
|
|
|
You can run dwl with `./dwl`. In an existing Wayland or X11 session,
|
|
dwl will open a Wayland or X11 window respectively to act as a virtual
|
|
display. You can then open Wayland windows by setting `WAYLAND_DISPLAY` to the
|
|
value shown in the logs. You can also run `./dwl` from a TTY.
|
|
|
|
In either case, you will likely want to specify `-s [cmd]` to run a command at
|
|
startup, such as a terminal emulator. This will be necessary to start any new
|
|
programs from within the compositor, as dwl does not support any custom
|
|
keybindings. dwl supports the following keybindings:
|
|
|
|
- `Alt+Escape`: Terminate the compositor
|
|
- `Alt+F1`: Cycle between windows
|
|
|
|
|
|
## Limitations
|
|
|
|
Notable omissions from dwl:
|
|
|
|
- HiDPI support
|
|
- Any kind of configuration, e.g. output layout
|
|
- Any protocol other than xdg-shell (e.g. layer-shell, for
|
|
panels/taskbars/etc; or Xwayland, for proxied X11 windows)
|
|
- Optional protocols, e.g. screen capture, primary selection, virtual
|
|
keyboard, etc. Most of these are plug-and-play with wlroots, but they're
|
|
omitted for brevity.
|
|
- Damage tracking, which tracks which parts of the screen are changing and
|
|
minimizes redraws accordingly.
