You need to install LuvvieScript and all its dependencies, obviously.
And you should read about the toolchain carefully.
Then got into
test/not_passing/src/ and have a good nosey around. Find a test you want to make pass and copy it into
You can use the erlang module
test_utils.erl to help you make a unit test in
to_js_ast.erl for that.
Then it is a matter of making and running the tests:
./build.sh rebar compile rebar make_tests rebar ct skip_deps=true
It will crash and burn (obviously, other wise the test would already be in
test/passing/src. But once you fix that, commit, get yer t-shirt, and move onto the next test.
