Syntax Errors Out of the Box

[markpwns1]

Hello, all I've done is wu create 3d and copy-pasted the sample code on the readme of this repo into src/init.wu, then git cloneed the repo into src and ran wu 3d and I get syntax errors (that make no sense) out of the box:

Obviously the source code already has newlines where it says it should have them. Adding newlines where it says to add them does not fix the error. Adding commas, however, does fix the error. I'm on 64-bit Windows 10 and have tried converting files to both LF line endings and CRLF, to no avail.

Does anyone know what's going on? Or is this likely a problem with the Wu language itself?

Hi! Thank you for pointing this out. I added some quick things to implement a feature request from the Discord a while back, and somewhy did not test it en this repo.

I believe this should be a simple fix, and will look into in later tonight. A fix is on its way.

Very cool, that you're trying to implement things in Wu! - and I am sorry that it this error made it less cool.

🥂🥂

To answer your question; I believe you have discovered a bug in the actual parser, where something is triggering a check at the wrong moment.

A-tier detective work.

is this fixed yet? I still can't use lover because of this exact bug, I'm even trying to fix the files myself and send a pull request...

@ThaCuber it hasn't been fixed yet unfortunately, we've been really busy for the past couple years. I will get some spare time in a few weeks I'll patch some bugs then.

If you manage to fix it by then we'll happily accept the PR :)
