# Builds Sandspiel (https://github.com/MaxBittker/sandspiel, MIT) for the site,
# from upstream source with sandspiel.diff beside this script, which:
# - takes out posting, browsing, likes and sign-in (they need sandspiel.club's
#   servers), its ads, analytics, error reporting and offline cache;
# - lays the board and the buttons out to fit the frame the play page puts
#   it in, with the buttons in one sideways-scrolling row when the frame is
#   narrow;
# - adds window.wg for the play page: the board as bytes (to save and load)
#   and pause.
# The Rust part is built with cargo and wasm-bindgen instead of wasm-pack,
# and the page with Sandspiel's own webpack setup, with the npm packages
# pinned by package-lock.json beside this script (and the crates by
# Cargo.lock).
#
# Needs git, a Rust toolchain with the wasm32-unknown-unknown target,
# wasm-bindgen-cli 0.2.129 (cargo install wasm-bindgen-cli --version 0.2.129)
# and Node 22.
# Usage: sh build.sh [work dir]
# Writes the page (sandspiel.html and its files) next to this script. The
# .wasm and chunk names change with the source: list them in the sandspiel
# entry of src/scripts/config.ts.
