problem with compiling function with empty body

[umegaya]

hi, I think there is great possibility for luajit-lang-toolkit. thank you for your great work :D I try to use luajit-lang-toolkit to implement some programming languages. but when I generate lua AST which expresses the lua function with empty body, I got error.

with further investigation I reproduce same problem with following simple lua source.

is it known problem or I was missing something about limitation of luajit-lang-toolkit?

regards.

Hi, thank you for reporting that, it is now fixed in the master branch with commit

https://github.com/franko/luajit-lang-toolkit/commit/838b951f65899330a6b707cde96582b5f795abe3

I've also added a specific test for this case in the test suite. You may interested to know that you can run the test suite with:

python tests/test-output.py

and

python tests/test-bytecode.py
