# CI builder image for Bevy projects: Rust toolchain with the
# wasm32-unknown-unknown target and the wasm-bindgen CLI preinstalled,
# so the pipeline's build step does not download them on every run.
#
# Debian-based (glibc) rather than alpine: the native linux binary needs
# glibc + alsa/udev dev libs (wgpu/winit), which bevy cannot build against
# musl. The windows binary is cross-compiled with mingw-w64
# (x86_64-pc-windows-gnu target). Mac is not cross-compiled here — that
# is the same osxcross story as the ebitengine mac targets.
#
# WASM_BINDGEN_VERSION must match the `wasm-bindgen` crate version pinned
# in the game repos' Cargo.toml (see README) — rebuild and retag this image
# when bumping it. The CLI is the x86_64 musl binary (static, runs on
# glibc too), so the image must be built for linux/amd64.
#
# Build & push (the CI runner is linux/amd64):
#   docker build --platform linux/amd64 -f builder.Dockerfile \
#     --build-arg WASM_BINDGEN_VERSION=0.2.100 \
#     -t git.teletypegames.org/build/bevy-builder:latest .
#   docker push git.teletypegames.org/build/bevy-builder:latest
