# wlroots
|
|
|
|
|
|
|
|
|
|
Pluggable, composable, unopinionated modules for building a [Wayland]
|
|
|
|
|
compositor; or about 60,000 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.

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.
