Depends on zigtools/zls#2594

Thanks! I'll take a look once ZLS is updated

zig build lint currently seems to pick up integration-tests/zig-pkg (which contains dependencies as of https://codeberg.org/ziglang/zig/pulls/31121) as files to be linted 🤔

[KurtWagner]

Oh https://codeberg.org/ziglang/zig/pulls/31121 is a nice change (I'm one of those people who vendors dependencies in projects).

I'm thinking we'd want to always exclude linting zig-pkg/ files so files.isLintableFilePath would need to be updated to also exclude zig-pkg/ files.

Going to approve and merge this in as it's a step forward and we can fix other master breaking changes in followups. Thanks for your contribution
