# Nulang compiler image - minimal binary with the WASM backend only.
#
# Used by nulang-cloud's nlc-deploy image as the NULANG_BIN compiler for the
# direct-upload Nulang source path (`compile_nulang` invokes
# `nulang --backend wasm --out <out> <input.nula>`). Built without the
# python/sqlite/lsp/ai-runtime features so the image stays small and has no
# Python runtime dependency.
#
# Build: docker build -f Dockerfile.compiler -t nulang .
