guix/run-wayland-game.scm

1;; Runtime packages for a game with sound (sigil-desktop + sigil-graphics +

2;; sigil-audio) as a native Wayland client on Guix:

3;;

4;; guix shell --pure -m guix/run-wayland-game.scm -- ./build/release/bin/<game>

5;;

6;; run-wayland.scm's three (mesa, wayland, libxkbcommon) plus the audio

7;; backend library miniaudio loads first on Linux:

8;;

9;; pulseaudio libpulse.so.0, the client library; on a PipeWire desktop

10;; the server is pipewire-pulse, PULSE_SINK picks the sink,

11;; and no configuration file is needed. Adds 187 MiB to the

12;; closure (`guix size`: 747.5 MiB against 560.1 MiB).

13;;

14;; The smaller alternative is alsa-lib (libasound.so.2, 3 MiB more): the

15;; ALSA backend then goes through the machine's ALSA configuration, which

16;; on a PipeWire desktop means the pipewire ALSA plugin and its

17;; /etc/alsa/conf.d entries, not something a pure shell brings along; a

18;; misconfigured ALSA route can also open a hardware device directly and

19;; bypass PULSE_SINK. Measured here with pulseaudio only (Crash The Stack,

20;; 2026-09-20: window on a headless sway, stream on the worker-null sink,

21;; LD_LIBRARY_PATH empty). A game's NEEDED list with sigil-graphics 0.11.4

22;; and sigil-audio 0.12.2 is libm, libc and the loader, so nothing else is

23;; resolved before main.
