 # dwl - dwm for Wayland
 
-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:
+Join us on our IRC channel: [#dwl on Libera Chat]  
+Or on the community-maintained [Discord server].
+
+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 a maximum number of SLOC (to be determined)
 - Tied to as few external dependencies as possible
 
+## Getting Started:
 
-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.  Since wlroots provides a number of features that are more complicated to accomplish with Xlib and select extensions, dwl can be in some ways more featureful than dwm *while remaining just as simple.*  Intended default features 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].
 
-- Any features provided by dwm/Xlib: simple window borders, tags, keybindings, client rules, mouse move/resize (see below for why the built-in status bar is a possible exception)
-- Configurable multi-monitor layout support, including position and rotation
-- Configurable HiDPI/multi-DPI support
-- Wayland protocols needed for daily life in the tiling world: at a minimum, xdg-shell and layer-shell (for bars/menus).  Protocols trivially provided by wlroots may also be added.
-- XWayland support as provided by wlroots
-- Zero flickering - Wayland users naturally expect that "every frame is perfect"
-- Basic yes/no damage tracking to avoid needless redraws (if it can be done simply and has an impact on power consumption)
+### 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)
 
+dwl has the following additional dependencies if XWayland support is enabled:
+- libxcb
+- libxcb-wm
+- wlroots (compiled with X11 support)
+- Xwayland (runtime only)
 
-Other features under consideration are:
-
-- Additional Wayland compositor protocols which are trivially provided by wlroots or can be conditionally included via `config.h` settings (e.g. screen capture)
-- External bar support instead of a built-in status bar, to avoid taking a dependency on FreeType or Pango
-- Buffering of input when spawning a client so you don't have to wait for the window (use `wl_client_get_credentials` to get the PID) - would this require passing through something like dmenu?  Extension protocol?
-- More in-depth damage region tracking
-
-
-Feature *non-goals* 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
-
-
-## Building dwl
-
-dwl has only two dependencies: wlroots (git version currently required) and wayland-protocols.  Simply install these and run `make`.
+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].
 
+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.
+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.
 
+As in the dwm community, we encourage users to share patches they have
+created. Check out the [dwl-patches] repository!
 
 ## Running dwl
 
-dwl can be run as-is, with no arguments. In an existing Wayland or X11 session, this will open a window to act as a virtual display.  When run from a TTY, the Wayland server will take over the entire virtual terminal.  Clients started by dwl will have `WAYLAND_DISPLAY` set in their environment, and other clients can be started from outside the session by setting this variable accordingly.
+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. 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.
 
-You can also specify a startup program using the `-s` option.  The argument to this option will be run at startup as a shell command (using `sh -c`) and can serve a similar function to `.xinitrc`: starting a service manager or other startup applications.  Unlike `.xinitrc`, the display server will not shut down when this process terminates.  Instead, as dwl is shutting down, it will send this process a SIGTERM and wait for it to terminate (if it hasn't already).  This makes it ideal not only for initialization but also for execing into a user-level service manager like s6 or `systemd --user`.
+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. Do note that the default background color is black. This can be
+modified in `config.h`.
 
-More/less verbose output can be requested with flags as well:
+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). This makes it ideal for execing into
+a user service manager like [s6], [anopa], [runit], [dinit], or [`systemd
+--user`].
 
-* `-q`: quiet (log level WLR_SILENT)
-* `-v`: verbose (log level WLR_INFO)
-* `-d`: debug (log level WLR_DEBUG)
-
-Note: Wayland requires a valid `XDG_RUNTIME_DIR`, which is usually set up by a session manager such as `elogind` or `systemd-logind`.  If your system doesn't do this automatically, you will need to configure it prior to launching `dwl`, e.g.:
+Note: The `-s` command is run as a *child process* of dwl, which means that it
+does not have the ability to affect the environment of dwl or of any processes
+that it spawns. 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`.  If your system doesn't do this
+automatically, you will need to configure it prior to launching `dwl`, e.g.:
 
     export XDG_RUNTIME_DIR=/tmp/xdg-runtime-$(id -u)
     mkdir -p $XDG_RUNTIME_DIR
+    dwl
 
+### Status information
 
-## Known limitations and issues
+Information about selected layouts, current window title, app-id, 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:
 
-dwl is a work in progress, and it has not yet reached its feature goals in a number of ways:
+    dwl -s 'foot --server <&-'
 
-- A window's texture is scaled for its "home" monitor only (noticeable when window sits across a monitor boundary)
-- XWayland support is new and could use testing
-- Urgent/attention/focus-request ([not yet supported](https://gitlab.freedesktop.org/wayland/wayland-protocols/-/merge_requests/9) by xdg-shell protocol)
-- Statusbar support (built-in or external)
-- layer-shell
-- Damage tracking
-- Fullscreen/fixed windows (or whatever the Wayland analogues are)
+If your startup command is a shell script, you can achieve the same inside the
+script with the line
 
+    exec <&-
+

+
+## Background
+
+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

-dwl began by extending the TinyWL example provided (CC0) by the sway/wlroots developers.  This was made possible in many cases by looking at how sway accomplished something, then trying to do the same in as suckless a way as possible.  Speaking of which, many thanks to suckless.org and the dwm developers and community for the inspiration.

+.Nm
+.Op Fl v
+.Op Fl d
+.Op Fl s Ar startup command
+.Sh DESCRIPTION
+.Nm
+is a Wayland compositor based on wlroots.
+It is intended to fill the same space in the Wayland world that
+.Nm dwm
+does for X11.
+.Pp
+When given the
+.Fl v
+option,
+.Nm
+writes its name and version to standard error and exits unsuccessfully.
+.Pp
+When given the
+.Fl d
+option,
+.Nm
+enables full wlroots logging, including debug information.
+.Pp
+When given the
+.Fl s
+option,
+.Nm
+starts a shell process running
+.Ar command
+when starting.
+When stopping, it sends
+.Dv SIGTERM
+to the child process and waits for it to exit.
+.Pp
+Users are encouraged to customize
+.Nm
+by editing the sources, in particular
+.Pa config.h .
+The default key bindings are as follows:

+        surface indicates that it would like to be moved to avoid occluding
+        surfaces with a positive exclusive zone. If set to -1, the surface
+        indicates that it would not like to be moved to accommodate for other
+        surfaces, and the compositor should extend it all the way to the edges
+        it is anchored to.
+
+        For example, a panel might set its exclusive zone to 10, so that
+        maximized shell surfaces are not shown on top of it. A notification
+        might set its exclusive zone to 0, so that it is moved to avoid
+        occluding the panel, but shell surfaces are shown underneath it. A
+        wallpaper or lock screen might set their exclusive zone to -1, so that
+        they stretch below or over the panel.
+
+        The default value is 0.
+

+        Types of keyboard interaction possible for layer shell surfaces. The
+        rationale for this is twofold: (1) some applications are not interested
+        in keyboard events and not allowing them to be focused can improve the
+        desktop experience; (2) some applications will want to take exclusive
+        keyboard focus.

+
+      <entry name="none" value="0">
+        <description summary="no keyboard focus is possible">
+          This value indicates that this surface is not interested in keyboard
+          events and the compositor should never assign it the keyboard focus.
+
+          This is the default value, set for newly created layer shell surfaces.
+
+          This is useful for e.g. desktop widgets that display information or
+          only have interaction with non-keyboard input devices.

+          Request exclusive keyboard focus if this surface is above the shell surface layer.
+
+          For the top and overlay layers, the seat will always give
+          exclusive keyboard focus to the top-most layer which has keyboard
+          interactivity set to exclusive. If this layer contains multiple
+          surfaces with keyboard interactivity set to exclusive, the compositor
+          determines the one receiving keyboard events in an implementation-
+          defined manner. In this case, no guarantee is made when this surface
+          will receive keyboard focus (if ever).
+
+          For the bottom and background layers, the compositor is allowed to use
+          normal focus semantics.
+
+          This setting is mainly intended for applications that need to ensure
+          they receive all keyboard events, such as a lock screen or a password
+          prompt.

+        <description summary="request regular keyboard focus semantics">
+          This requests the compositor to allow this surface to be focused and
+          unfocused by the user in an implementation-defined manner. The user
+          should be able to unfocus this surface even regardless of the layer
+          it is on.
+
+          Typically, the compositor will want to use its normal mechanism to
+          manage keyboard focus between layer shell surfaces with this setting
+          and regular toplevels on the desktop layer (e.g. click to focus).
+          Nevertheless, it is possible for a compositor to require a special
+          interaction to focus or unfocus layer shell surfaces (e.g. requiring
+          a click even if focus follows the mouse normally, or providing a
+          keybinding to switch focus between layers).
+
+          This setting is mainly intended for desktop shell components (e.g.
+          panels) that allow keyboard interaction. Using this option can allow
+          implementing a desktop shell that can be fully usable without the
+          mouse.
