Wayland + +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]. 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` +- Tied to as few external dependencies as possible + +## Getting Started: + +### **dwl branch 0.7 and releases based upon 0.7 build against [wlroots] 0.18** + +### 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]. + +### 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) + +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. + +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 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. + +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`. + +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`]. + +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 + +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 -s 'foot --server <&-' + +If your startup command is a shell script, you can achieve the same inside the +script with the line + + exec <&- + +To get a list of status bars that work with dwl consult our [wiki]. + +## Replacements for X applications + +You can find a [list of useful resources on our wiki]. + +## 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 + +## Acknowledgements + +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. + +Many thanks to suckless.org and the dwm developers and community for the +inspiration, and to the various contributors to the project, including: + +- **Devin J.

Generally this will be the one that the user most + recently interacted with. + + Clients can specify a namespace that defines the purpose of the layer + surface. + + + + + + + + + + + + + + + + + These values indicate which layers a surface can be rendered in. They + are ordered by z depth, bottom-most first. Traditional shell surfaces + will typically be rendered between the bottom and top layers. + Fullscreen shell surfaces are typically rendered at the top layer. + Multiple surfaces can share a single layer, and ordering within a + single layer is undefined. + + + + + + + + + + + + + This request indicates that the client will not use the layer_shell + object any more. Objects that have been created through this instance + are not affected. + + + + + + + An interface that may be implemented by a wl_surface, for surfaces that + are designed to be rendered as a layer of a stacked desktop-like + environment. + + Layer surface state (layer, size, anchor, exclusive zone, + margin, interactivity) is double-buffered, and will be applied at the + time wl_surface.commit of the corresponding wl_surface is called. + + Attaching a null buffer to a layer surface unmaps it. + + Unmapping a layer_surface means that the surface cannot be shown by the + compositor until it is explicitly mapped again. The layer_surface + returns to the state it had right after layer_shell.get_layer_surface. + The client can re-map the surface by performing a commit without any + buffer attached, waiting for a configure event and handling it as usual. + + + + + Sets the size of the surface in surface-local coordinates. The + compositor will display the surface centered with respect to its + anchors. + + If you pass 0 for either value, the compositor will assign it and + inform you of the assignment in the configure event. You must set your + anchor to opposite edges in the dimensions you omit; not doing so is a + protocol error. Both values are 0 by default. + + Size is double-buffered, see wl_surface.commit. + + + + + + + + Requests that the compositor anchor the surface to the specified edges + and corners. If two orthogonal edges are specified (e.g. 'top' and + 'left'), then the anchor point will be the intersection of the edges + (e.g. the top left corner of the output); otherwise the anchor point + will be centered on that edge, or in the center if none is specified. + + Anchor is double-buffered, see wl_surface.commit. + + + + + + + Requests that the compositor avoids occluding an area with other + surfaces. The compositor's use of this information is + implementation-dependent - do not assume that this region will not + actually be occluded. + + A positive value is only meaningful if the surface is anchored to one + edge or an edge and both perpendicular edges. If the surface is not + anchored, anchored to only two perpendicular edges (a corner), anchored + to only two parallel edges or anchored to all edges, a positive value + will be treated the same as zero. + + A positive zone is the distance from the edge in surface-local + coordinates to consider exclusive. + + Surfaces that do not wish to have an exclusive zone may instead specify + how they should interact with surfaces that do. If set to zero, the + 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. + + Exclusive zone is double-buffered, see wl_surface.commit. + + + + + + + Requests that the surface be placed some distance away from the anchor + point on the output, in surface-local coordinates. Setting this value + for edges you are not anchored to has no effect. + + The exclusive zone includes the margin. + + Margin is double-buffered, see wl_surface.commit. + + + + + + + + + + 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. + + + + + 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. + + + + + 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. + + + + + + + Set how keyboard events are delivered to this surface. By default, + layer shell surfaces do not receive keyboard events; this request can + be used to change this. + + This setting is inherited by child surfaces set by the get_popup + request. + + Layer surfaces receive pointer, touch, and tablet events normally. If + you do not want to receive them, set the input region on your surface + to an empty region. + + Keyboard interactivity is double-buffered, see wl_surface.commit. + + + + + + + This assigns an xdg_popup's parent to this layer_surface. This popup + should have been created via xdg_surface::get_popup with the parent set + to NULL, and this request must be invoked before committing the popup's + initial state. + + See the documentation of xdg_popup for more details about what an + xdg_popup is and how it is used. + + + + + + + When a configure event is received, if a client commits the + surface in response to the configure event, then the client + must make an ack_configure request sometime before the commit + request, passing along the serial of the configure event. + + If the client receives multiple configure events before it + can respond to one, it only has to ack the last configure event. + + A client is not required to commit immediately after sending + an ack_configure request - it may even ack_configure several times + before its next surface commit. + + A client may send multiple ack_configure requests before committing, but + only the last request sent before a commit indicates which configure + event the client really is responding to. + + + + + + + This request destroys the layer surface. + + + + + + The configure event asks the client to resize its surface. + + Clients should arrange their surface for the new states, and then send + an ack_configure request with the serial sent in this configure event at + some point before committing the new surface. + + The client is free to dismiss all but the last configure event it + received. + + The width and height arguments specify the size of the window in + surface-local coordinates. + + The size is a hint, in the sense that the client is free to ignore it if + it doesn't resize, pick a smaller size (to satisfy aspect ratio or + resize in steps of NxM pixels). If the client picks a smaller size and + is anchored to two opposite anchors (e.g. 'top' and 'bottom'), the + surface will be centered on this axis. + + If the width or height arguments are zero, it means the client should + decide its own window dimension. + + + + + + + + + The closed event is sent by the compositor when the surface will no + longer be shown. The output may have been destroyed or the user may + have asked for it to be removed. Further changes to the surface will be + ignored. The client should destroy the resource after receiving this + event, and create a new surface if they so choose. + + + + + + + + + + + + + + + + + + + + + + Change the layer that the surface is rendered on. + + Layer is double-buffered, see wl_surface.commit. + + + + + diff --git a/protocols/wlr-output-power-management-unstable-v1.xml b/protocols/wlr-output-power-management-unstable-v1.xml new file mode 100644 index 0000000..a977839 --- /dev/null +++ b/protocols/wlr-output-power-management-unstable-v1.xml @@ -0,0 +1,128 @@ + + + + Copyright © 2019 Purism SPC + + Permission is hereby granted, free of charge, to any person obtaining a + copy of this software and associated documentation files (the "Software"), + to deal in the Software without restriction, including without limitation + the rights to use, copy, modify, merge, publish, distribute, sublicense, + and/or sell copies of the Software, and to permit persons to whom the + Software is furnished to do so, subject to the following conditions: + + The above copyright notice and this permission notice (including the next + paragraph) shall be included in all copies or substantial portions of the + Software. + + THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR + IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, + FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
