Does setfenv still work or do I need to switch to _ENV?

troysandal · July 17

I'm trying to debug what's wrong with my app and noticed that the wax library I'm using still uses setfenv which the Gideros docs say is deprecated. Before I start changing a bunch of code around, my question is, does this still work?

If you look at this line of code you'll see it calls the method waxClass which in turn calls setfenv(2, class._M). It passes 2 which means it's replacing the environment of caller which is the module being loaded. I'm not sure yet how to port this to use _ENV. If setfenv is still working then maybe I don't have to?

Would love an expert opinion, couldn't find anything searching Google. Thanks in advance.

According to luau docs (https://luau.org/library#global-functions), setfenv is still supported.

Thank you, that reduces my problem surface area.

Update - While the setfenv() is still supported in Luau it has dropped support for Userdata types. Here's the Luau implementation and here is the Lua 5.1 implementation (that I was depending on).

FYI I'm trying to get Wax working again on both Lua 5.x and Luau so I can get my game back up and running. It depended heavily on Wax and it's been quite a journey. You can see my progress so far here and here and here.

@troysandal I’m also a big fan of WAX and really enjoy using it because of its simplicity and the ability to call native iOS libraries and SDKs. If you have any updates, please share them, and if you need testing on iOS I’d be glad to help. That way I can also revisit setting up a Gideros + WAX project to call native iOS functions.
