Sway can be compiled with or without systemd(-logind) and dbus. This
commit exposes that support via the global systemdSupport and
dbusSupport arguments, which are understood by many other nixpkgs
expressions and can be set globally in ~/.config/nixpkgs/config.nix.
This commit also adds a third argument, trayEnabled, which allows to
disable sway's tray. The tray requires dbusSupport and
systemdSupport.
Reviewers of this commit asked for potential use cases. There are
many of them; a very non-exhaustive list includes:
* Use of nixpkgs on operating systems which systemd does not support,
such as MacOS/Darwin, FreeBSD, OpenBSD, or Alpine Linux.
* Use of nixpkgs on *-musl platforms, which systemd does not
officially support (out-of-tree patches to support musl exist for a
few systemd versions).
* Use of sway in situations where dbus is inappropriate, such as
sway's "kiosk mode".
* High-security environments, where the additional attack surface
exposed by dbus outweighs any features it may offer.
This is a very non-exhaustive list.
This commit exposes support for compilation without systemd,
controlled by the global systemdSupport argument. This argument is
understood by many other nixpkgs expressions and can be set globally
in ~/.config/nixpkgs/config.nix.
Release notes: https://github.com/swaywm/sway/releases/tag/1.7
Notable (backward incompatible) changes:
- The default terminal changed from Alacritty to foot
Known issues:
- `swaynag` will crash when Sway 1.6.1 is still running while the Nix
package (and thus `swaynag`) is already updated to version 1.7.
- The experimental Ozone/Wayland support of Electron apps will be broken
for a while. Electron version 17 should work but the Chromium fixes
haven't yet been backported to Electron version 16.
NixOS module: programs.sway.extraPackages: The "alacritty" package was
replaced with "foot".
VM test: We switched from the OpenGL ES 2.0 renderer to Pixman. The
terminal was also changed to foot but Alacritty is still used for the
XWayland test (since foot doesn't support X11).
