luacheck.yml

# ATTENTION
#
# This is *not* a typical luacheck workflow! Do not copy this to other projects!
# Instead of installing luacheck from somewhere and using it on a code base,
# we're actually building and running the current HEAD version on ourselves:
# basically this is a combination bootstrap test and dogfooding. The upshot is
# that we check both that everything works (and end-to-end test) and that the
# current codebase lints against itself. This ensures we can fix a bug or make
# a breaking change in luacheck without being blocked by our own CI using a
# different luacheck verision.
#
# See the README.md file for examples suitable for use in other projects.
