python-lua's Issues

in operator can be used in list and dicts, not just lists

According to this :

python-lua/pythonlua/luainit.lua

Line 388 in 5e61488

function operator_in(item, items)

It only checks if it's a list, but you could use in in python even for hashtables, then you would need in lua just to do

if dict[key] then

python code being

if key in dict

This project is great! But why the performance is still better on native python?

Hello, I am originally a Python enthusiast but after some point my clients can't keep up with Python's performance. So I was at an adventure for searching transpilers/translator or a even a language that have similar syntax (because that's what make python great, our team have a great consulting performance even sometimes we code in front of our clients, but not computing performance surely). And now we actually have already found a working transpiler called Rapydscript (python to JS), but still we want more. Lua is now one of the most stable language to be ran on WebAssembly. And then I search for python to Lua transpiler/translator and found your project which is awesome. But on our simple benchmarks Lua is not that faster compared to Python 3 even sometimes slower. And that's even the luajit, the native lua interpreter is 3x slower. Do you have any insights on this?

Ignoring things not defined

This is a very interesting project, Dmitrii!

Is there a way to make the translator ignore things missing in the code and generate a translation anyway?

I wanted to code in Python the use of functions from binary Lua modules (C Lib), and then after translating they would of course be executed and loaded by Lua. But I get errors saying that this or that "is not defined" and the import will also try to locate a local Python script, so the compilation fails

Tests failures

I ran the tests on Python 3.6 & 3.8 and seven of the tests seem to have failures: simple_math (minor), unaryop, listdict, variables (minor), comprehensions, continue, for

Did you ever have decent programming lessons before releasing this rubbish?

You can't convert python to lua by inserting the keyword "local" in front of each line of code.

Try to convert this one and you'll see:
https://github.com/Broham/suncalcPy/blob/master/suncalc.py

Good free advice from me: delete this project, take a decent programming course and then try again.

PyPI

The package name in setup.py does not appear to be registered on PyPI https://pypi.org/project/pythonlua/

Unable to run using python-lua

I have installed it with success but my system does not recognize the command python-lua.

I am on Ubuntu.

This is a very useful project, eager to use it.

Thanks a lot !
