module Overcommit::Hook::PreCommit
# Runs `eslint` against any modified JavaScript files.
#
# Protip: if you have an npm script set up to run eslint, you can configure
# this hook to run eslint via your npm script by using the `command` option in
# your .overcommit.yml file. This can be useful if you have some eslint
# configuration built into your npm script that you don't want to repeat
# somewhere else. Example:
#
# EsLint:
# required_executable: 'npm'
# enabled: true
# command: ['npm', 'run', 'lint', '--', '-f', 'compact']
#
# Note: This hook supports only compact format.
#
# @see http://eslint.org/
class EsLint < Base

# example message:
# path/to/file.js: line 1, col 0, Error - Error message (ruleName)
