eslint-plugin-editorconfig

An ESLint plugin to enforce EditorConfig rules

Install

$ npm install --save-dev eslint eslint-plugin-editorconfig

or

$ yarn add --dev eslint eslint-plugin-editorconfig

If you use typescript-eslint, you need to install @typescript-eslint/eslint-plugin too.

$ npm install --save-dev @typescript-eslint/eslint-plugin

Usage

Like other ESLint plugins,

• add rules in the rules
• add "editorconfig" in the plugins

in your .eslintrc*

{
  // ...
  "rules": {
    "editorconfig/charset": "error",
    "editorconfig/eol-last": "error",
    "editorconfig/indent": "error",
    "editorconfig/linebreak-style": "error",
    "editorconfig/no-trailing-spaces": "error"
  },
  "plugins": [ "editorconfig" ]
}

Or you can extend plugin:editorconfig/all instead of adding rules.

{
  // ...
  "extends": [ "plugin:editorconfig/all" ],
  "plugins": [ "editorconfig" ]
}

Conflicting ESLint rules

Following rules may conflict editorconfig/* rule. It is recommended to disable them.

• eol-last
• indent
• linebreak-style
• no-trailing-spaces
• unicode-bom
• @typescript-eslint/eol-last
• @typescript-eslint/indent
• @typescript-eslint/linebreak-style
• @typescript-eslint/no-trailing-spaces
• @typescript-eslint/unicode-bom

If above rules are specified in your .eslintrc, just remove them. If they are specified in the extended config, consider adding plugin:editorconfig/noconflict to your extends.

{
  "extends": [
    "@phanect/phanective",
    "plugin:editorconfig/noconflict"
  ],
  // ...
}

If you extend plugin:editorconfig/all, the rules above are turned off too, so you don't have to add plugin:editorconfig/noconflict in addition to plugin:editorconfig/all.

Rules

Internally, eslint-plugin-editorconfig uses the existing ESLint and typescript-eslint rules to verify/fix the code. Some rules allow passing options.

All the citation in the docs is from the backend ESLint rule document otherwise noted.

| Rule | Description | Fixable | | ------------------------------------------------------------------- | --------------------------------------------------------------- | -- | | editorconfig/charset | Enforce EditorConfig rules for charset | ✅ | | editorconfig/eol-last | Enforce EditorConfig rules for the newlines at the end of files | ✅ | | editorconfig/indent | Enforce EditorConfig rules for indentation | ✅ | | editorconfig/linebreak-style | Enforce EditorConfig rules for linebreak style | ✅ | | editorconfig/no-trailing-spaces | Enforce EditorConfig rules for trailing spaces | ✅ |
