Build Status

Ruby wrapper for JSHint. The main difference from jshint it does not depend on Java. Instead it uses ExecJS.

Installation

jshintrb is available as ruby gem.

$ gem install jshintrb

Ensure that your environment has a JavaScript interpreter supported by ExecJS. Usually, installing therubyracer gem is the best alternative.

Usage

require 'jshintrb'

Jshintrb.lint(File.read("source.js"))
# => array of warnings

Jshintrb.report(File.read("source.js"))
# => string

Or you can use it with rake

require "jshintrb/jshinttask"
Jshintrb::JshintTask.new :jshint do |t|
  t.pattern = 'javascript/**/*.js'
  t.options = :defaults
end

When initializing Jshintrb, you can pass options

Jshintrb::Lint.new(:undef => true).lint(source)
# Or
Jshintrb.lint(source, :undef => true)

List of all available options

If you pass :defaults as option, it is the same as if you pass following

{
  :bitwise => true,
  :curly => true,
  :eqeqeq => true,
  :forin => true,
  :immed => true,
  :latedef => true,
  :newcap => true,
  :noarg => true,
  :noempty => true,
  :nonew => true,
  :plusplus => true,
  :regexp => true,
  :undef => true,
  :strict => true,
  :trailing => true,
  :browser => true
}

If you pass :jshintrc as option, .jshintrc file is loaded as option.
