Ruby wrapper for JSHint

jshintrb

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
}

Upgrading

1. Update the latest jshint via npm or bower.
2. Replace vendor/jshintrb with the file in dist directory.
3. Commit your changes.

TODO

• add more tests
• add color reporter. Maybe colorize
• add cli. Support same options as jshint/node-jshint
