adds queries for highglights and more

[y0m0]

Hi, first of all thanks a lot for the amazing work with the al plugin for treesitter.
Finally I can try to have a fully working AL setup for neovim in combination with al.nvim
With that said the al.nvim project included the queries which were missing from this repo, but in my opinion it's more natural for them to be part of the al treesitter.

I added queries for:

• highlights
• locals
• folds (not fully working yet)
• indents (not fully working yet)

Here's the healthcheck for treesitter:

And here's how the highlight works for an .al file in neovim:

Code Review: Query Files for Editor Integration

Thanks for this contribution! Adding query files significantly improves editor support for AL. The coverage is comprehensive and the documentation within the files is excellent.

✅ What's Good

• Comprehensive coverage - All AL object types, sections, and constructs are covered
• Well-documented - Clear section headers and explanatory comments
• Scanner fix - Replacing GCC statement expressions (({ })) with match_keyword_case_insensitive() improves portability (MSVC compatibility)
• README updates - Good documentation of the new query files

⚠️ Issues to Address

1. Keyword captures are too broad (High Priority)

Many patterns capture entire nodes instead of specific keyword tokens:

; Current - highlights entire declaration including body
(table_declaration) @keyword
(if_statement) @keyword.control

; Should be - highlights only the keyword token
(table_declaration "table" @keyword)
(if_statement "if" @keyword.control)
(if_statement "then" @keyword.control)
(if_statement "else" @keyword.control)

This affects most entries in the "KEYWORDS" sections of highlights.scm.

2. Conflicting indent rules (Medium Priority)

indents.scm has three different captures for }:

"}" @indent_end
"}" @dedent
"}" @outdent

Most editors expect only one pattern. Recommend keeping just @indent / @dedent (nvim-treesitter convention).

3. package-lock.json regression (Medium Priority)

The PR downgrades tree-sitter-cli from 0.24.4 to 0.24.3. This appears unintentional - please revert.

4. AL scoping semantics (Low Priority)

In locals.scm:

(code_block) @local.scope
(if_statement) @local.scope

AL has procedure-level variable scoping, not block scoping. Variables in a var section are visible throughout the entire procedure. This could cause incorrect scope highlighting, though it may be acceptable for initial implementation.

5. README test count (Low Priority)

README says "1,198 tests" but current count is 1,194. Minor, but worth correcting.

💡 Suggestions

1. Consider adding a few test .al files with expected highlighting to catch regressions
2. For the "not fully working" folds/indents, consider adding TODO comments noting specific issues

Verdict

This is a valuable addition! The main blocker is the overly broad keyword captures which will cause entire code blocks to be highlighted as keywords. Once that's fixed, this should be good to merge.

Happy to help test or review a follow-up commit!
