ZLint

An opinionated linter for the Zig programming language.

Warning

This project is still very much under construction.

Features

• ZLint has its own semantic analyzer, heavily inspired by the Oxc project, that is completely separate from the Zig compiler. This means that ZLint still checks and understands code that may otherwise be ignored by Zig due to dead code elimination.
• Pretty, detailed, and easy-to-understand error messages.

Lint Rules

All lints and what they do can be found here.

Configuration

Create a zlint.json file in the same directory as build.zig. This disables all default rules, only enabling the ones you choose.

{
  "rules": {
    "no-undefined": "error",
    "homeless-try": "warn"
  }
}

Contributing
