special treate for return values of require
sumneko commentedon Feb 2, 2023
File can only return one value, I will add a diagnostic about it.

ehh, well, in some environments it can return more than one, can we have a switch or something for that?
sumneko commentedon Feb 2, 2023
This is a non-standard behavior.
There are countless non-standard behaviors in the world, and I don't want to add switches to them one by one.
artemking4 commentedon Feb 2, 2023
well, this library already supports non-standard environments, like love2d and special operators like /*, //, && and ||, so why not add this? Personally, i would expect this to be a feature even in the vanilla lua, not sure if it actually supports that though.
Is it something that is hard to implement maybe?

This is why I added https://github.com/sumneko/lua-language-server/wiki/Plugins .
Besides,
/*,//are famous non-standard symbols, like I built in some famous environment definition files such aslove2d,skynet.
