ECHint

Quick validation of files with EditorConfig.

Install

The easiest way to use ECHint to check your code is to install it globally as a Node command line program. To do so, simply run the following command in your terminal (flag -g installs echint globally on your system, omit it if you want to install in the current working directory):

npm install --only=production --save --global echint

After you've done that you should be able to use the echint CLI. The simplest use case would be checking all files in the current working directory:

$ echint
Error: some files did not pass EditorConfig validation:
  src/index.js:97 Expected a newline at the end of the file.
  src/path/data.json:2 Unexpected tabs found.

You can optionally pass one or more paths using the glob pattern:

$ echint *.js docs/**/*.md

How do I ignore files?

The path node_modules/** and hidden files/folders (beginning with .) are automatically excluded when looking for files to check.

Sometimes you need to ignore additional folders or specific minified files. To do that, add a echint.ignore property to package.json:

"echint": {
  "ignore": [
    "**/out/**",
    "**/build/**"
  ]
}

Can I use a sharable configuration?

Yes, you may prefer to check your code against a centralized .editorconfig. To do that, add a echint.extends property to package.json:

"echint": {
  "extends": "echint-config-some-config"
}

echint will use the main property or .editorconfig file from that package as the configuration. The echint-config- prefix will be added automatically if it is not already present.

use your ENV

echint uses dotenv to load the following environment config values:

name	type	description
ECHINT_CONFIG	string	path to .editorconfig file
ECHINT_IGNORE	string	pattern of files to ignore
ECHINT_PATTERN	string	pattern of file to process
ECHINT_READ_PACKAGE	string	read additional options from package.json ("true", "false")

you can create a local .env or .env.[NODE_ENV] file to modify echint's default behavior (where NODE_ENV is the name of your environment), or you can test this directly from the shell:

$ ECHINT_CONFIG=**/* echint *.js docs/**/*.md

include in your tests

1. Add it to package.json

{
  "name": "my-cool-package",
  "devDependencies": {
    "echint": "^1.0.0"
  },
  "scripts": {
    "test": "echint && node my-tests.js"
  }
}

1. Validate all files automatically when you run npm test

$ npm test
Error: some files did not pass EditorConfig validation:
  src/index.js:97 Expected a newline at the end of the file.
  src/path/data.json:2 Unexpected tabs found.

1. Never deal with inconsistencies in a pull request again!

API

echint()

validate everything in current directory

echint(files, [, options [, callback]]])

returns true | false

Parameters

name	type	description	required	default
files	mixed	manually defined list of files to process	no	**/*
options	mixed	see options	no
callback	mixed	see callback	no	undefined

Options

name	type	description	required	default
config	string	path to .editorconfig file	no	**/*
ignore	array	array of files & patterns to ignore	no	['coverage/**', 'node_modules/**', 'bower_components/**', '**[.jpg,.png,.gif,.ico]
pattern	string	pattern of file to process	no	**/*
readPackage	boolean	read additional options from package.json	no	true

Callback

pass a callback with the following signature:

function (errors, result) {
  /* typeof errors === 'object' */
  /* typeof result === 'boolean' */
 
  /*
    errors = {
      fileName: {
        lineNumber: [
          error details
        ]
      }
    }
  */
}

Examples

  config: 'path/to/.editorconfig'
}
 
function done (errors, valid) {
  if (!valid) {
    console.log(errors)
  }
}
 
// with defaults
