Sway 1.5 custom environment release using Wayland

Prepared compositing manager release sway 1.5, built using the Wayland protocol and fully compatible with the tiled window manager i3 and panel i3bar. The project code is written in C language and spreads under the MIT license. The project is intended for use on Linux and FreeBSD.

Compatibility with i3 is provided at the level of commands, configuration files and IPC, which allows Sway to be used as a transparent replacement for i3, using Wayland instead of X11. Sway allows you to place windows on the screen not spatially, but logically. Windows are laid out in a grid that makes optimal use of screen space and allows you to quickly manipulate windows using only the keyboard.

For the arrangement of a full-fledged user environment, related components are offered: we ate (background process with KDE idle protocol implementation), swaylock (screen saver) mako (notification manager), makeup (create screenshots) slurps (selection of an area on the screen), wf-recorder (video capture), waybar (app bar), virtboard (screen keyboard), wl-clipboard (work with clipboard), wallutils (desktop wallpaper management).

Sway develops as a modular project built on top of a library wlroots, which contains all the basic primitives for organizing the work of the composite manager. Wlroots includes backends for
abstraction of screen access, input devices, rendering without direct access to OpenGL, interaction with KMS / DRM, libinput, Wayland and X11 (a layer is provided for running X11 applications based on Xwayland). In addition to Sway, the wlroots library is also actively used in other projectsIncluding freem5 и Cage. In addition to C/C++, bindings have been developed for Scheme, Common Lisp, Go, Haskell, OCaml, Python, and Rust.

In the new release:

• Added the ability to dynamically organize output on systems without a monitor (headless) using the create_output command (can be used to organize remote access to the worker via WayVNC).
• Through Wayland protocols input-method and text-input support for input method editors (IMEs) has been implemented.
• Provided the ability to enable adaptive synchronization (VRR, Variable Refresh Rate) to reduce image judder in games.
• Added support for the viewporter protocol to improve the performance and quality of older games.
• Virtualization systems and remote access to the desktop are given the ability to intercept keyboard combinations.
• Protocol support added wlr-foreign-toplevel-management, allowing you to connect your own panels and window switches.
