How to make `max-attributes-per-line` work only when over maximum line length

See original GitHub issue

Tell us about your environment

ESLint Version: 4.16.0
eslint-plugin-vue Version: 4.2.0
Node Version: 9.2.0

Please show your full configuration:

.eslintrc.js

module.exports = {
  extends: [
    'standard',
    'plugin:vue/recommended',
    'prettier',
  ],
  plugins: ['prettier'],
  parserOptions: {
    parser: 'babel-eslint',
    sourceType: 'module',
  },
  env: {
    browser: true,
    jest: true,
  },
  rules: {
    'prettier/prettier': 'error',

    // allow debugger during development
    'no-debugger': process.env.NODE_ENV === 'production' ? ['error'] : ['warn'],

    'no-param-reassign': ['error', { props: false }],

    'vue/html-closing-bracket-newline': [
      'error',
      {
        singleline: 'never',
        multiline: 'always',
      },
    ],

    'vue/html-closing-bracket-spacing': [
      'error',
      {
        startTag: 'never',
        endTag: 'never',
        selfClosingTag: 'always',
      },
    ],
  },
}

What did you do? Please include the actual source code causing the issue.

<MyComponent lorem="1" ipsum="2" />

<MyComponent lorem="1" ipsum="2" @click="longlonglonglonglonglongFunctionName" @change="longlonglonglonglonglongFunctionName2" />

What did you expect to happen? What i want is max-attributes-per-line rule should be available only when over maximum line length option, like printWidth defined in prettier.

For example, I set printWidth: 80 in prettier:

<MyComponent lorem="1"  ipsum="2" />

<MyComponent 
  lorem="1"
  ipsum="2"
  @click="longlonglonglonglonglongFunctionName" 
  @change="longlonglonglonglonglongFunctionName2"
/>

What actually happened? Please include the actual, raw output from ESLint.

As the default value of multilple option in max-attributes-per-line rule is 1, so the output will be:

<MyComponent
  lorem="1"
  ipsum="2"
/>

<MyComponent 
  lorem="1"
  ipsum="2"
  @click="longlonglonglonglonglongFunctionName" 
  @change="longlonglonglonglonglongFunctionName2"
/>
