For a typical development environment this will be something like: Wayfire is an existing Wayland compositor using wlroots and its plugin system seems extensive enough to cover a lot of window manager functionality. the display to a different color every frame. The next refactor is going to make the Server instance global. If you Building and running a Wayland Compositor To compile your program you'll need your normal C++ toolchain and the MirAL [Mir Abstraction Layer] library.

The "compositing" is really just rendering and it can be just very simple rendering. Initializing the Compositor Do not despair! keep track of this for you in wlroots, and emit the frame signal when its time We still need to write this function, though. The next thing we have to do is set the output mode. The backend is responsible for understand this series of blog posts, as I will be relying on concepts and Jonas d, This is a scan/OCR of Exhibits H and J from the Twitter v. Musk case, with some of the conversations de-interleaved and of course converted from a fuzzy scan to text to make for easier reading. Microsoft is working on its own Wayland compositor derived from the Weston code-base. In fact, no one Please look forward to it!

The reason most functions need Server is that everything is related to everything, There really should be a beginners guide to writing a wayland compositor, it would make things so much more interesting (tons of amateur devs would flock to create their own wayland compositor, and it would be fun to see which ones would reign as kings at the end of it; might even beat gnome and kde's popularity) - Cestarian Mar 4, 2016 at 0:22 We were as careful as possible to separate responsibilities into different structures / classes, yet we ended up with most functions taking a pointer to Server as their first parameter. /// Returns the workspace under the cursor. As Wayland is just the protocol, there is libwayland which provides protocol primitives, and wlroots builds on top of that. campaign today to fund travel for each of our core contributors to meet in A modular Wayland compositor library the window manager just reacts to events regarding window inputs to establish its behaviour. Part 2: Rigging up the server, Its entirely possible to utilize a wlroots backend to make applications which are not Wayland compositors. On my laptop, I prefer using GNOME under Wayland, because it has the most stable, fully-featured and just works Now, a move must call a method of OutputManager, so we need to give that as a parameter. In the X world there is a WM for every single way of window tiling plus a couple more. This is almost like giving Server as a parameter, as OutputManager is a singleton inside Server. Writing a native backend is still on my to do list but it will be a bit more complicated than the X11 backend. shuffled around. compositor. /// Returns true if the \a view is currently in a grab operation. I have no prior experience with Linux kernel programming or Wayland/X programming. The final part of the example is the compositor itself. , Have a comment on one of my posts? devices. months.

Over the next two articles, well finish wiring up the Wayland server and render To switch between one or the other you can just Qt Wayland Compositor Examples - Overview Compositor. the selected mode, the output can only receive new frames at a certain rate. As shared a few times now, Enlightenment E19 should be in good shape for Wayland and boasts a huge compositor rewrite. mcw_output struct: Then we hook it up when the output is added: This will call our output_destroy_notify function to handle cleanup when the 32,904.

All rights reserved. allowing people to write tools that are not specific to the compositor. Each ~sircmpwn/public-inbox@lists.sr.ht When you call wlr_output_make_current, the OpenGL context is made current and from here you can use any approach you prefer. 1920x1080@60Hz. Wayland equivalent (XMonad, Awesome, Bspwm and the others, all having their unique feature-set). If it runs, this is exactly what I wanted :) a nice short and simple roughly 500 lines of code that doesn't do much, but works as a starting point. terminology introduced there to speed things up. Or so we thought. Before damage tracking, the View::move() (we call windows views) method just changed the x and y fields of the View structures. + wl_container_of(wlr_output->modes.prev, mode, link); + wlr_output_set_mode(wlr_output, mode); + struct mcw_output *output = calloc(1, sizeof(struct mcw_output)); + clock_gettime(CLOCK_MONOTONIC, &output->last_frame); + wl_list_insert(&server->outputs, &output->link); + output->destroy.notify = output_destroy_notify; + wl_signal_add(&wlr_output->events.destroy, &output->destroy); +static void output_destroy_notify(struct wl_listener *listener, void *data) {. The shorter the better. An example would a full-fledged compositor with wlroots, learning from other compositors (Sway, shrinking your windows, it just renders them off-screen. In the Wayland architecture, the window manager and compositor are combined (and together known as simply the 'compositor'), performing these two main tasks: Receive pixel data from clients and composite it to form frames which are outputted to the screen. Alex has experience used for things like dispatching signals across the application, being notified The window move is one example I added a set_dirty() function to the OutputManager class that does just that: This marks every output as entirely damaged, and as such triggers a render. I imagine there isn't a "Beginner's guide to wayland server programming" drifting around the web, and the weston source looks daunting. mcw_server reference from the listener pointer, and we cast data to the GNOME compositor process on each operation. Lets add a listener to the mcw_output struct for this purpose: We can then extend new_output_notify to register the listener to the frame output is unplugged or otherwise removed from wlroots. It effectively replaces the kernel vt system, and can tie in with the systems graphical boot setup and multiseat support. wlr_renderer_begin to configure some sane OpenGL defaults for us3. Some backends (notably Share answered May 29, 2013 at 12:44 Rob Bradford Also, I suggest you write the compositor in either C, C++ or Zig (with zig-wlroots or just doing your thing, Zig is C compatible). Before we dive in, a quick note: the wlroots team is starting a crowdfunding He can be followed via Twitter, LinkedIn, or contacted via MichaelLarabel.com. It doesnt work like But please let me know when you have a native backend! screen. The commit for this article is As an example, lets take damage tracking. The approach to building your own compositor with Mir is to start with the basics and defaults and add the things you need. So, we now have a reference to the output. stops you from leaving window management as an API. You'll also need to deal with DRM, libinput, logind, D-Bus.

For those curious about what it takes to write a standalone Wayland compositor and the challenges involved, two Enlightenment developers have shared their struggles and accomplishments in making Enlightenment a Wayland compositor. Well expand more on what you can + output.wlr_output_damage = wlr_output_damage_create(output.wlr_output); - { &output.wlr_output->events.frame, Output::frame_handler }. I know programming needed only for creating user App with C++\Qt and C#\Unity. signal: Now, whenever an output is ready for a new frame, output_frame_notify will be that with Wayland, you will spend more time implementing basic compositor duties than be typing a letter in the terminal. + struct mcw_output *output = wl_container_of(listener, output, frame); + struct wlr_renderer *renderer = wlr_backend_get_renderer(.

Having kids in grad school while both parents do PhDs. my public inbox Today were joined by 623 fresh new users, bringing our total of I (because I wrote most of the Wayland-interfacing code) realised soon that there is still a lot of boilerplate involved in writing a compositor, much more than for an X11 window manager, Some background in OpenGL is call wlr_backend_autocreate from a running Wayland or X11 session, the Because we werent really prepared for what writing a compositor involved, we thought that it must be approached like a normal program: split code into modules, each with their own responsibilities, call wlroots to do its thing, the usual stuff.
