Support CfxLua #338

mdxwzl · 2025-02-09T02:25:07Z

Implemented CFX Lua as a feature flag - cfxlua
- Compound Operators: +=, -=, *=, /=, <<=, >>=, &=, |=, and ^=
- Safe Navigation e.g. t?.x?.y == nil
- In Unpacking e.g. local a, b, c = t is equivalent to local a, b, c = t.a, t.b, t.c
- Set Constructors e.g. t = { .x, .y } is equivalent to t = { x = true, y = true }
- C-Style Comments (single & multiline) e.g. /* comment */
- Compile Time Jenkins' Hashes e.g. `Hello, World!` -> 1395890823

Some of the tests dont pass in the workflow, I'll look into it tmrw

mdxwzl · 2025-02-10T08:37:35Z

Would be glad if someone can look over it. I tested the workflows locally with Docker, and it keeps changing up the bytes, line & character values in the AST. Somehow, they are not the same in the workflow environment as on my Windows machine.

Test should run now

JohnnyMorganz

Thanks for this! I had an initial look - I haven't looked deep into the parser / tokenizer changes yet, I will do this in a follow up

Can we re-export the types here? To reduce the breaking change on downstream users

+    CaretEqual(TokenReference),

Should these be gated via cfg(feature = "luau") flags if they are only available in luau?

Some with the below for CfxLua

+    LeftShift(TokenReference),
+    RightShift(TokenReference),
+    BitwiseAndAssignment(TokenReference),
+    BitwiseOrAssignment(TokenReference),


To align with the other options. We try to make the names represent the characters rather than the logic, since in future >>= could mean something other than right shift operator for a different Lua dialect

Suggested change

LeftShift(TokenReference),

RightShift(TokenReference),

BitwiseAndAssignment(TokenReference),

BitwiseOrAssignment(TokenReference),

DoubleLessThanEqual(TokenReference),

DoubleGreaterThanEqual(TokenReference),

AmpersandEqual(TokenReference),

PipeEqual(TokenReference),

Since cfxlua already extends lua54, we don't need to change this config since lua54 should always be enabled

I don't quite understand this condition.

We can remove the visit_compound_assignment from the Luau section above and then use any

Looks like this was introduced by your IDE.

You should reference it through ast::Var instead, which is already exported
