SublimeLinter-eslint

This linter plugin for SublimeLinter provides an interface to ESLint. It will be used with files that have the “javascript” syntax.

Installation

SublimeLinter 3 must be installed in order to use this plugin. If SublimeLinter 3 is not installed, please follow the instructions here.

Linter installation

Before using this plugin, you must ensure that eslint is installed on your system. To install eslint, do the following:

  1. Install Node.js (and npm on Linux).

  2. Install eslint globally by typing the following in a terminal:

    npm install -g eslint
    

    Or install eslint locally in your project folder (you must have package.json file there):

    npm init -f
    npm install eslint
    
  3. Init eslint config if you don't have any. Run in your code folder:

    eslint --init
    

    or if eslint is installed locally

    ./node_modules/.bin/eslint --init
    

Reopen your project next (or restart ST) to make sure local eslint will be used.

  1. If you are using nvm and zsh, ensure that the line to load nvm is in .zprofile and not .zshrc.

  2. If you are using zsh and oh-my-zsh, do not load the nvm plugin for oh-my-zsh.

Once eslint is installed, you must ensure it is in your system PATH so that SublimeLinter can find it. This may not be as straightforward as you think, so please read about how linter executables are located in the documentation.

Once you have installed eslint you can proceed to install the SublimeLinter-eslint plugin if it is not yet installed.

Note: This plugin requires eslint 1.0.0 or later.

Plugin installation

Please use Package Control to install the linter plugin. This will ensure that the plugin will be updated when new versions are available. If you want to install from source so you can modify the source code, you probably know what you are doing so we won’t cover that here.

To install via Package Control, do the following:

  1. Within Sublime Text, bring up the Command Palette and type install. Among the commands you should see Package Control: Install Package. If that command is not highlighted, use the keyboard or mouse to select it. There will be a pause of a few seconds while Package Control fetches the list of available plugins.

  2. When the plugin list appears, type eslint. Among the entries you should see SublimeLinter-contrib-eslint. If that entry is not highlighted, use the keyboard or mouse to select it.

Settings

For general information on how SublimeLinter works with settings, please see Settings. For information on generic linter settings, please see Linter Settings.

You can configure eslint options in the way you would from the command line, with .eslintrc files. For more information, see the eslint docs.

FAQ and Troubleshooting

What is my first step to find out what trouble I have?

Use SublimeText console and SublimeLinter debug mode.

  1. Check Tools -> SublimeLinter -> Debug Mode.
  2. Open console View -> Show Console.

Then open any JS file and run Tools -> SublimeLinter -> Lint This View. It must be an output in console after, something like that:

SublimeLinter: eslint: 1.js ['/Projects/sample/node_modules/.bin/eslint', '--format', 'compact', '--stdin', '--stdin-filename', '@'] 
I've got 'SublimeLinter: ERROR: eslint cannot locate 'eslint' in ST console when I try to use locally installed eslint.

You must have package.json file if install eslint locally. Also, restart project or ST itself after to make sure SublimeLinter uses correct eslint instance.

npm init -f
npm install eslint
Plugin still does not work or there are errors in ST console.

Update eslint instance, probably you use outdated version and SublimeLinter does not check it properly sometimes.

There are no errors in console, but plugin does nothing.

ESLint >2.0.0 does not enable any default rules and you should have config file for your code. Run in your console:

eslint --init # if eslint is global
./node_modules/.bin/eslint --init # if eslint is installed locally
I want plugin to use my .eslintignore settings.

It does it now.

For ESLint <2.0.0

Add to your SublimeLinter settings (global or per-project):

{
    "linters": {
        "eslint": {
            "args": [
                "--stdin-filename", "__RELATIVE_TO_FOLDER__"
            ]
        }
    }
}

It can limit some rules and probably cause some bugs (i.e. files in symlinked folders can be skipped).

For ESLint >=2.0.0 or if previous solution can't be applied

Duplicate ESLint ignore settings to your .sublimelinterrc file. Use double stars for correct match.

{
    "linters": {
        "eslint": {
            "excludes": [
                "**/node_modules/**",
                "**/vendor/**"
            ]
        }
    }
}
For ESLint >=2.0.0

If you use a SublimeText project and .sublime-project file is in project folder, set chdir to ${project} in your SublimeLinter settings. Warning: it can cause bugs if your project has more than one root folder.

I want not to lint files if there is no .eslintrc file in project folder (for ESLint <1.0.0).

Use --reset ESLint option, add it to your SublimeLinter global settings or project .sublimelinterrc file as below. Add --no-reset option to project .sublimelinterrc to overwrite it back.

{
    "linters": {
        "eslint": {
            "args": [
                "--reset"
            ]
        }
    }
}
I want to use global .eslintrc config.

Plugin uses the same configuration hierarchy as eslint itself, so add .eslintrc to your home directory or ancestor directory of project.

I want to use custom rules, global .eslintignore file, etc.

You can specify any CLI options of eslint with args key in SublimeLinter configs.

{
    "linters": {
        "eslint": {
            "args": [
                "--ignore-path", "~/eslint_ignore",
                "--rulesdir", "~/rules"
            ]
        }
    }
}
There is no SublimeLinter-contrib-eslint package to install in Package Control packages list.

Check if you already have it installed, please.

It's not linting for JSX.

Try changing your syntax from JSX to Babel > Javascript. (ref issue)

Contributing

If you would like to contribute enhancements or fixes, please do the following:

  1. Fork the plugin repository.
  2. Hack on a separate topic branch created from the latest master.
  3. Commit and push the topic branch.
  4. Make a pull request.
  5. Be patient. ;-)

Please note that modifications should follow these coding guidelines:

  • Indent is 4 spaces.
  • Code should pass flake8 and pep257 linters.
  • Vertical whitespace helps readability, so don’t be afraid to use it.
  • Please use descriptive variable names, so no abbreviations unless they are very well known.

Thank you for helping out!
