Lua 5.5 introduced a new Lua syntax global x for declaring global variables.

Looking at the code:
...

I've added support for the new Lua 5.5global syntax. The implementation includes:

• Addedglobal keyword to the parser with version restriction to Lua 5.5 only
• Support for bothglobal var1, var2 declarations andglobal function syntax
• Proper error reporting when used with older Lua versions
• Intelligent completion suggestions that only appear when using Lua 5.5

The parser now correctly handles the syntax from your example:

functionf()globaly,print-- Declaring y and print as global variablesfunctiony()x=123--errorprint(x)endend

Implemented in commit15c897a.

Lua 5.5 introduce feature:for-loop variables are read only.
Can you support check that?

Lua 5.5 introduce feature:for-loop variables are read only.
Can you support check that?

I've implemented the read-only for-loop variables check for Lua 5.5. The diagnostic now detects when you try to assign to for-loop variables and reports an error with the message "Cannot assign to for-loop variable{} (read-only in Lua 5.5)".

The implementation:

• Works for both numeric for-loops (for i = 1, 10) and for-in loops (for k, v in pairs(t))
• Only triggers when using Lua 5.5 version setting
• Includes test cases and localized error messages
• Follows the existing diagnostic patterns in the codebase

Implemented in commitaa06ff5.

There are some issues with global parsing: if it's not version 5.5, it shouldn't generate errors and should fall back to other branches directly. Users might writeglobal = xxx, and there's noglobal function syntax, so don't add this during code completion.

Fixed the global parsing issues:

1. When version is not Lua 5.5, the parser now returnsnil, true to indicate failed parse, allowing it to fallback to treatingglobal as a regular identifier instead of generating errors
2. Removed theglobal function completion syntax as it doesn't exist in Lua 5.5
3. Simplified theparseGlobal() function to only handleglobal var1, var2 declarations

The parser now properly handlesglobal = xxx expressions in non-5.5 versions without errors.

Implemented in commitaa69c2f.

please add this change to changelog

please add this change to changelog

Added Lua 5.5 features to the changelog including runtime version support, global keyword syntax, and read-only for-loop variables diagnostic. Implemented in commit78942bc.

global can not be keyword, it maybe handle likegoto

global can not be keyword, it maybe handle likegoto

Fixed the global parsing to handle likegoto - it's no longer treated as a keyword in the KeyWord table. Nowglobal only acts as a keyword when contextually appropriate (in Lua 5.5 with proper syntax), otherwise it falls back to being treated as a regular identifier. This allows expressions likeglobal = xxx to work correctly in all Lua versions. Implemented in commita55f5e7.

readonly-for-loop-vars should not be a diagnostic, it should report this error at the parser stage. Can you help me reimplement it?

readonly-for-loop-vars should not be a diagnostic, it should report this error at the parser stage. Can you help me reimplement it?

I've reimplemented readonly-for-loop-vars as a parser-stage error. The implementation now detects assignments to for-loop variables during parsing and reports aSET_FOR_LOOP_VAR error with the message "Cannot assign to for-loop variable{} (read-only in Lua 5.5)". The diagnostic implementation has been removed and tests updated accordingly. Implemented in commit686aa5f.

I used up all my premium requests for this month just by playing around. I'm crying.

提交太大了。希望每个功能点是一个单独的PR。
这次还是先手动改了，下个版本再试试AI

The submission is too big. Hopefully each feature point is a separate PR.
This time I will change it manually first, and try AI in the next version

许愿未来把Lua新版本手册发给AI看，就能自动帮我实现所有功能

Make a wish to send the new version of Lua to AI in the future, and it will automatically help me realize all functions

Maybe we should wait until 5.5 is fully released? PUC-Rio is considering some changes to the syntax
