 # dwl - dwm for Wayland
 
-Join us on our [Discord server](https://discord.gg/jJxZnrGPWN)!
+Join us on our IRC channel: [#dwl on Libera Chat]  
+Or on our [Discord server].
 
-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:
+dwl is a compact, hackable compositor for [Wayland] based on [wlroots]. It is
+intended to fill the same space in the Wayland world that dwm does in X11,
+primarily in terms of functionality, and secondarily in terms of
+philosophy. 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`
-- Limited to 2000 SLOC to promote hackability
 - Tied to as few external dependencies as possible
 
-dwl is not meant to provide every feature under the sun. Instead, like dwm, it sticks to features which are necessary, simple, and straightforward to implement given the base on which it is built. Implemented default features are:
+## Getting Started:
 
-- Any features provided by dwm/Xlib: simple window borders, tags, keybindings, client rules, mouse move/resize. Providing a built-in status bar is an exception to this goal, to avoid dependencies on font rendering and/or drawing libraries when an external bar could work well.
-- Configurable multi-monitor layout support, including position and rotation
-- Configurable HiDPI/multi-DPI support
-- Idle-inhibit protocol which lets applications such as mpv disable idle monitoring
-- Provide information to external status bars via stdout/stdin
-- Urgency hints via xdg-activate protocol
-- Support screen lockers via input-inhibitor protocol
-- Various Wayland protocols
-- XWayland support as provided by wlroots (can be enabled in `config.mk`)
-- Zero flickering - Wayland users naturally expect that "every frame is perfect"
-- Layer shell popups (used by Waybar)
-- Damage tracking provided by scenegraph API
+### **dwl branch 0.7 and releases based upon 0.7 build against [wlroots] 0.18**
 
-Features under consideration (possibly as patches) are:
+### Latest semi-stable [release]
+This is probably where you want to start. This builds against the dependent
+packages' versions currently shipping in major distributions. If your
+distribution's wlroots version is older, use an earlier dwl [release] or [0.x
+branch].
 
-- Protocols made trivial by wlroots
-- Implement the text-input and input-method protocols to support IME once ibus implements input-method v2 (see https://github.com/ibus/ibus/pull/2256 and https://github.com/djpohly/dwl/pull/12)
+### Development branch [main]
+Active development progresses on the `main` branch. The `main` branch is built
+against a late (and often changing) git commit of wlroots. While the adventurous
+are welcome to use `main`, it is a rocky road. Using `main` requires that the
+user be willing to chase git commits of wlroots. Testing development pull
+requests may involve merging unmerged pull requests in [wlroots]' git repository
+and/or git commits of wayland.
+  
+### Building dwl
+dwl has the following dependencies:
+- libinput
+- wayland
+- wlroots (compiled with the libinput backend)
+- xkbcommon
+- wayland-protocols (compile-time only)
+- pkg-config (compile-time only)
 
-Feature *non-goals* for the main codebase include:
+dwl has the following additional dependencies if XWayland support is enabled:
+- libxcb
+- libxcb-wm
+- wlroots (compiled with X11 support)
+- Xwayland (runtime only)
 
-- Client-side decoration (any more than is necessary to tell the clients not to)
-- Client-initiated window management, such as move, resize, and close, which can be done through the compositor
-- Animations and visual effects
+Install these (and their `-devel` versions if your distro has separate
+development packages) and run `make`. If you wish to build against a released
+version of wlroots (*you probably do*), use a [release] or a [0.x branch]. If
+you want to use the unstable development `main` branch, you need to use the git
+version of [wlroots].
 
-## Building dwl
-
-dwl has only two dependencies: `wlroots` and `wayland-protocols`. 
-
-Simply install these (and their `-devel` versions if your distro has separate development packages) and run `make`.  If you wish to build against a Git version of wlroots, check out the [wlroots-next branch](https://github.com/djpohly/dwl/tree/wlroots-next).
-
-To enable XWayland, you should also install xorg-xwayland and uncomment its flag in `config.mk`.
+To enable XWayland, you should uncomment its flags in `config.mk`.
 
 ## Configuration
 
-All configuration is done by editing `config.h` and recompiling, in the same manner as dwm. There is no way to separately restart the window manager in Wayland without restarting the entire display server, so any changes will take effect the next time dwl is executed.

 ## Running dwl
 
-dwl can be run on any of the backends supported by wlroots. This means you can run it as a separate window inside either an X11 or Wayland session, as well as directly from a VT console. Depending on your distro's setup, you may need to add your user to the `video` and `input` groups before you can run dwl on a VT.

+add your user to the `video` and `input` groups before you can run dwl on a
+VT. If you are using `elogind` or `systemd-logind` you need to install polkit;
+otherwise you need to add yourself in the `seat` group and enable/start the
+seatd daemon.
 
-When dwl is run with no arguments, it will launch the server and begin handling any shortcuts configured in `config.h`. There is no status bar or other decoration initially; these are instead clients that can be run within the Wayland session.

+decoration initially; these are instead clients that can be run within the
+Wayland session. Do note that the default background color is black. This can be
+modified in `config.h`.
 
-If you would like to run a script or command automatically at startup, you can specify the command using the `-s` option. This command will be executed as a shell command using `/bin/sh -c`.  It serves a similar function to `.xinitrc`, but differs in that the display server will not shut down when this process terminates. Instead, dwl will send this process a SIGTERM at shutdown and wait for it to terminate (if it hasn't already).

If you need to set environment variables that affect the entire dwl session, these must be set prior to running dwl.  For example, Wayland requires a valid `XDG_RUNTIME_DIR`, which is usually set up by a session manager such as `elogind` or `systemd-logind`.

 ### Status information
 
-Information about selected layouts, current window title, and selected/occupied/urgent tags is written to the stdin of the `-s` command (see the `printstatus()` function for details).  This information can be used to populate an external status bar with a script that parses the information.  Failing to read this information will cause dwl to block, so if you do want to run a startup command that does not consume the status information, you can close standard input with the `<&-` shell redirection, for example:

-## IRC channel
+## Background
 
-dwl's IRC channel is #dwl on irc.libera.chat.
+dwl is not meant to provide every feature under the sun. Instead, like dwm, it
+sticks to features which are necessary, simple, and straightforward to implement
+given the base on which it is built. Implemented default features are:
+
+- Any features provided by dwm/Xlib: simple window borders, tags, keybindings,
+  client rules, mouse move/resize. Providing a built-in status bar is an
+  exception to this goal, to avoid dependencies on font rendering and/or drawing
+  libraries when an external bar could work well.
+- Configurable multi-monitor layout support, including position and rotation
+- Configurable HiDPI/multi-DPI support
+- Idle-inhibit protocol which lets applications such as mpv disable idle
+  monitoring
+- Provide information to external status bars via stdout/stdin
+- Urgency hints via xdg-activate protocol
+- Support screen lockers via ext-session-lock-v1 protocol
+- Various Wayland protocols
+- XWayland support as provided by wlroots (can be enabled in `config.mk`)
+- Zero flickering - Wayland users naturally expect that "every frame is perfect"
+- Layer shell popups (used by Waybar)
+- Damage tracking provided by scenegraph API
+
+Given the Wayland architecture, dwl has to implement features from dwm **and**
+the xorg-server. Because of this, it is impossible to maintain the original
+project goal of 2000 SLOC and have a reasonably complete compositor with
+features comparable to dwm. However, this does not mean that the code will grow
+indiscriminately. We will try to keep the code as small as possible.
+
+Features under consideration (possibly as patches) are:
+
+- Protocols made trivial by wlroots
+- Implement the text-input and input-method protocols to support IME once ibus
+  implements input-method v2 (see https://github.com/ibus/ibus/pull/2256 and
+  https://codeberg.org/dwl/dwl/pulls/235)
+
+Feature *non-goals* for the main codebase include:
+
+- Client-side decoration (any more than is necessary to tell the clients not to)
+- Client-initiated window management, such as move, resize, and close, which can
+  be done through the compositor
+- Animations and visual effects

+  <description summary="Control power management modes of outputs">
+    This protocol allows clients to control power management modes
+    of outputs that are currently part of the compositor space. The
+    intent is to allow special clients like desktop shells to power
+    down outputs when the system is idle.
+
+    To modify outputs not currently part of the compositor space see
+    wlr-output-management.
+
+    Warning! The protocol described in this file is experimental and
+    backward incompatible changes may be made. Backward compatible changes
+    may be added together with the corresponding interface version bump.
+    Backward incompatible changes are done by bumping the version number in
+    the protocol and interface names and resetting the interface version.
+    Once the protocol is to be declared stable, the 'z' prefix and the
+    version number in the protocol and interface names are removed and the
+    interface version number is reset.
