Rule Configuration

Lint rules are configured in chant.config.ts under the lint key.

Basic Configuration

export default {
  lint: {
    rules: {
      "EVL001": "error",
      "COR004": "warning",
      "COR008": "off",
    },
  },
} satisfies ChantConfig;

Severity Levels

Severity	Effect
"error"	Fails the lint run (non-zero exit code)
"warning"	Reported but does not fail
"info"	Informational notice
"off"	Disables the rule entirely

Presets

Use extends to inherit rule configurations:

export default {
  lint: {
    extends: ["@intentius/chant/lint/presets/strict"],
    rules: {
      "COR004": "off",  // override preset
    },
  },
} satisfies ChantConfig;

Presets are resolved recursively. Local rules override inherited ones.

File-Specific Overrides

Apply different rule settings to specific file patterns:

export default {
  lint: {
    rules: { "COR004": "warning" },
    overrides: [
      {
        files: ["src/legacy/**/*.ts"],
        rules: { "COR004": "off" },
      },
    ],
  },
} satisfies ChantConfig;

Rule Options

Some rules accept an options object as the second element of a tuple:

rules: {
  "COR009": ["warning", { max: 12 }],
}
