This commits completely refactors wlr_gtk_primary_selection. The goal is to remove gtk-primary-selection state from the seat and better handle inert resources where it makes sense. wlr_seat_client.primary_selection_devices has been removed and replaced by wlr_gtk_primary_selection_device. This allows us to make offers inert when the current selection is replaced. wlr_seat_set_primary_selection has been removed because it relied on wlr_seat instead of wlr_gtk_primary_selection_device_manager. A new function, wlr_gtk_primary_selection_device_manager_set_selection (candidate for the longest function name in wlroots) has been added. It doesn't take a serial anymore as serial checking only makes sense for set_selection requests coming from Wayland clients (serial checking is now done in the Wayland interface implementation). Since wlr_gtk_primary_selection_device_manager is now required to set the selection, a new function wlr_xwayland_set_gtk_primary_selection_device_manager (candidate number two for longest function name) has been added. Devices are now made inert when the seat goes away. Future work includes removing the last primary selection bits from the seat, mainly wlr_seat.primary_selection_source and wlr_seat.events.primary_selection, replacing those with new fields in wlr_gtk_primary_selection_device. Or maybe we could keep those in the seat and replace them with a re-usable interface (for future zwp_primary_selection_v1 support). We need to think how we'll sync these three protocols (GTK, X11 and wayland-protocols). See https://github.com/swaywm/wlroots/issues/1388 |

wlroots
Pluggable, composable, unopinionated modules for building a Wayland compositor; or about 50,000 lines of code you were going to write anyway.
- wlroots provides backends that abstract the underlying display and input hardware, including KMS/DRM, libinput, Wayland, X11, and headless backends, plus any custom backends you choose to write, which can all be created or destroyed at runtime and used in concert with each other.
- wlroots provides unopinionated, mostly standalone implementations of many Wayland interfaces, both from wayland.xml and various protocol extensions. We also promote the standardization of portable extensions across many compositors.
- wlroots provides several powerful, standalone, and optional tools that implement components common to many compositors, such as the arrangement of outputs in physical space.
- wlroots provides an Xwayland abstraction that allows you to have excellent Xwayland support without worrying about writing your own X11 window manager on top of writing your compositor.
- wlroots provides a renderer abstraction that simple compositors can use to avoid writing GL code directly, but which steps out of the way when your needs demand custom rendering code.
wlroots implements a huge variety of Wayland compositor features and implements them right, so you can focus on the features that make your compositor unique. By using wlroots, you get high performance, excellent hardware compatibility, broad support for many wayland interfaces, and comfortable development tools - or any subset of these features you like, because all of them work independently of one another and freely compose with anything you want to implement yourself.
Check out our wiki to get started with wlroots.
wlroots is developed under the direction of the sway project. A variety of wrapper libraries are available for using it with your favorite programming language.
Building
Install dependencies:
- meson
- wayland
- wayland-protocols
- EGL
- GLESv2
- libdrm
- GBM
- libinput
- xkbcommon
- udev
- pixman
- systemd (optional, for logind support)
- elogind (optional, for logind support on systems without systemd)
- libcap (optional, for capability support)
If you choose to enable X11 support:
- xcb
- xcb-composite
- xcb-xfixes
- xcb-xinput
- xcb-image
- xcb-render
- x11-xcb
- xcb-errors (optional, for improved error reporting)
- x11-icccm (optional, for improved Xwayland introspection)
Run these commands:
meson build
ninja -C build
Install like so:
sudo ninja -C build install
Running the test compositor
wlroots comes with a test compositor called rootston, which demonstrates the features of the library and is used as a testbed for the development of the library. It may also be useful as a reference for understanding how to use various wlroots features, but it's not considered a production-quality codebase and is not designed for daily use.
If you followed the build instructions above the rootston executable can be
found at ./build/rootston/rootston. To use it, refer to the example config at
./rootston/rootston.ini.example
and place a config file of your own at rootston.ini in the working directory
(or in an arbitrary location via rootston -C). Other options are available,
refer to rootston -h.
