Install

npm install --save-dev commitlint-plugin-function-rules @commitlint/cli @commitlint/config-conventional

Usage

Use this plugin in your project's commitlint configuration by specifying it as item in the plugins array. All rules have same name as rules that are available in commitlint, but with the function-rules prefix. The example commitlint.config.js, or commitlint.config.cjs if the package is an ES module, shows the usage of a function rule.

Note The available rules are the same as in commitlint, so it is recommended to disable the commitlint rule when specifying a function rule to avoid undefined behaviour.

module.exports = {
  extends: ['@commitlint/config-conventional'],
  plugins: ['commitlint-plugin-function-rules'],
  rules: {
    'header-max-length': [0], // level: disabled
    'function-rules/header-max-length': [
      2, // level: error
      'always',
      (parsed) => {
        // Allow longer headers for commits with "deps" scope.
        if (parsed.scope === 'deps' && parsed.header.length <= 200) {
          return [true];
        }
        return [false, 'deps header must not be longer than 200 characters'];
      },
    ],
  },
};
