# danger-eslint

A [Danger](https://github.com/danger/danger) plugin for [eslint](http://eslint.org/).

## Installation

    $ gem install danger-eslint
    
`eslint` also needs to be installed(global or local) before you run Danger, Please check the [installation guide](http://eslint.org/docs/user-guide/getting-started)
`danger-eslint` will first try local `node_module/.bin/eslint` then the global `eslint`.

## Usage
Run lint without and configuration will do the samething as run `eslint .`  
All lint result will send as individual comment. If your are using Github, the comment will show as a inline comment directly on the violation's position if possiable.

    eslint.lint

Also, you can pass a config file or eslintignore file to danger-eslint with:

    eslint.config_file = /path/yourconfig
    eslint.ignore_file = /path/yourigonre
    eslint.lint
    
If you want to lint only new/modified files. You can achieve that with setting the `filtering` parameter to `true`.

    eslint.filtering = true
    eslint.lint

If you want to lint files with specified extension, you can set extensions to the `target_extensions` parameter.  
The default value is `['.js']`. In the case of the example below, the value will be `['.js', '.es6']`.

    eslint.target_extensions += %W(.es6)
    eslint.lint

If you want to specify eslint's bin file, you can set a bin path to the `bin_path` parameter.

    eslint.bin_path = "/hoge/node_modules/.bin/eslint"
    eslint.lint
