# CI toolbox image for the TIC-80 pipeline's lint / minify / docs steps:
# Lua 5.4 with luacheck and ldoc preinstalled, so the pipeline does not
# run luarocks (and a C compiler install) on every run.
#
# The export step keeps using the separate TIC-80 Pro image
# (git.teletypegames.org/internal/tic80pro, built from the tic80pro-dockerfile
# repo) — this image only covers the Lua tooling around it.
#
# Build & push (the CI runner is linux/amd64):
#   docker build --platform linux/amd64 -f builder.Dockerfile \
#     -t git.teletypegames.org/internal/tic80-luatools:latest .
#   docker push git.teletypegames.org/internal/tic80-luatools:latest
