The image builds Lua 5.5.1 from its pinned official release commit. Luacheck runs separately on Debian's Lua 5.4 and checks the syntax shared by both versions.

The exercises use Lua's built-in assertions. To run their tests without Docker, install Lua 5.5 and run the following command from this repository.

make local-test

If another Lua version is the default, select the 5.5 interpreter explicitly.

make local-test LUA_BIN=/path/to/lua5.5

Solutions live in index.lua. The platform removes the region between -- BEGIN and -- END to prepare the learner's starter code. Function exercises keep a final return outside that region, so the tests can load and call the submitted function. Tests use the shared helper in lib/test_helper.lua through bin/test.sh. The modules exercise also includes a ready-to-use pricing.lua fixture.
