Zig grammar for tree-sitter

Showcase
1

tree-sitter-zig:

I was thinking about creating a tree-sitter grammar for zig before the college semester starts but it takes more time than a thought (3 weeks), not even full released yet.

I did some progress because of Programming Languages cource; Improved on emacs and jj-vcs, got mad a moment but worth it . Want to learn forgejo workflow now

There is already a grammar for zig, perhaps you overlooked it: tree-sitter-zig/grammar.js at master · tree-sitter-grammars/tree-sitter-zig · GitHub

There is a list of them on https://github.com/tree-sitter/tree-sitter/wiki/List-of-parsers, this one is more similar to mine. It even got great pull requests, but they aren’t merged.

I think I can learn from them to improve my implementation, that’s good

I can now parse every .zig/.zon on zig source code excluding:

  • some on test/cases/compile_errors
  • doc/langref/var_must_be_initialized.zig
  • doc/langref/tldoc_comments.zig
  • doc/langref/unattached_doc-comment.zig

Tested some repos and the only thing I have found was a ambiguity on index expressions with range, block expression and sentinel like: const a = b[0.. blk: { break :blk 1; } :0];

Changed repo to github for workflows;

Parsed the following projects:

As a side note, codeberg has CI/actions which are pretty similar to GitHub. You need to apply for it but since your project is GPL it’s likely to get auto approved.
