question: using python functions on lua tables about lupa

[amm0x41r]

Ok, so this seems to work:

def lua_table_to_python_obj(obj):
    if type(obj).__name__ == "_LuaTable":
        # Check if the Lua table is array-like
        keys = list(obj.keys())
        if keys == list(range(1, len(keys) + 1)):
            # Convert to Python list if keys are consecutive integers starting from 1
            return [lua_table_to_python(obj[key]) for key in keys]
        else:
            # Convert to Python dictionary otherwise
            return {key: lua_table_to_python(obj[key]) for key in obj}
    return obj

Is this truly what I'm meant to do? recursively convert tables to objects by hand? or am I missing something obvious?

I'd use lupa.lua_type(obj) == 'table', and try to avoid the list(range()), but yes, it would usually be something like this, depending on your specific needs. It's not clear that an implementation in Lupa would cover a sufficiently large number of use cases, but since users can always implement their own mapping, it might still work out.

Want to provide a PR that adds this as a method of the _LuaTable class, say, .copy_to_python()?

I'd expect that this can be made quite fast when using the Lua C-API instead of going through Lupa's Python API.
