How to change lua version? (actual problem: linter disabling)

Questions
#1

i updated the engine to 1.9.1, and now my game won’t compile because i was using features that aren’t in the (now) packaged lua version.

Lua 5.1 does not support this grammar.(Supported in Lua 5.2/Lua 5.3/Lua 5.4/LuaJIT, current is Lua 5.1.)

#2

We have no way to change the Lua version. LuaJIT is our main library, and it’s Lua 5.1 compatible (while it does have a tiny amount of newer features)

#3

well in such a case it’s an undocumented breaking change

#4

I don’t think it’s undocumented:

However, it’s unfortunate that we previously haven’t been able to verify builds more correctly as we do now. We do consider this a bug fix after all (i.e. to correctly point out the code issue)

#5

i mean between the release notes of 1.8.1 and 1.9.1 there’s no mention of a change in lua version

#6

Yeah, we haven’t changed version?

We’ve added more linting tools that help highlight issues.

#7

then why doesn’t my code compile in 1.9.1?

#8

Do you know more specifically what in your code isn’t working? Any particular keyword or construct?

As I mentioned above, the linting tools have been added to highlight compatibility issues.
You can try disabling it in the preferences:

goto, a cheifly >=5.2/JIT thing

#11

ok. This makes it compile.
Thank you.
