;;;; sand.flan's other half: N frames, no window, hash the grid.

;;;;
|
|
;;;; This is the version CI runs on native *and* wasm32, and it imports
|
|
;;;; sand.flan itself — window, raylib bindings, dev agent and all. It builds
|
|
;;;; for wasm32 anyway because the link follows what the program reaches:
|
|
;;;; nothing here calls into raylib, so no shim is compiled and no -lraylib is
|
|
;;;; passed, and the front-end's own functions are never emitted. sand.flan's
|
|
;;;; main is not exported, so the only main is this one.
|
|
;;;;
|
|
;;;; A package is a directory, except when it is a single .flan file named
|
|
;;;; outright — which is this, because sand.flan shares the repository root
|
|
;;;; with three other loose programs.
|
|
;;;;
|
|
;;;; The hash is a regression test only because the sequence is reproducible:
|
|
;;;; rand is a seeded PRNG written in Flan, so the same seed gives the same
|
|
;;;; grains in the same places on both targets (plan.org, RNG is ours).
