traceur-rb
This gem provides a Ruby wrapper around Google Traceur.
Google Traceur
Google Traceur is a transpiler, which allows you to compile ECMAScript 6 (JS.next) features in today's browsers.
Dependencies
Google Traceur depends on Node.js. On Ubuntu, you can install Node.js with command:
sudo apt-get install nodeInstallation
Add this line to your application's Gemfile:
gem 'traceur-rb'
And then execute:
$ bundle
Or install it yourself as:
$ gem install traceur-rb
Basic Usage
You can compile a snippet of ECMAScript 6 by calling the following method:
require 'traceur'
compiled_source = Traceur.compile(es6_source, additional_compilation_flags) similarly, you can compile a file using:
require 'traceur'
compiled_source = Traceur.compile_file(path_to_es6_file, additional_compilation_flags)Configuration
traceur-rb can be configured using a Traceur.configure:
Traceur.configure do |c|
# Configure path of the node.js binary.
# By default, traceur-rb loooks for node in $PATH.
c.node_binary = "/path/to/node"
# Configure path of node_modules folder, where
# traceur is installed.
# By default, traceur-rb uses traceur version
# which comes bundled with the gem.
c.node_modules_path = "/path/to/node_modules/"
# Configure path to traceur-runtime.js, which is
# a runtime dependency of the code compiled using
# Google Traceur.
# By default, this is computed based on node_modules_path.
c.traceur_runtime_path = "/path/to/node_modules/traceur/bin/traceur-runtime.js"
# Configure the default compilation options.
# For a complete list of options available, see:
# https://github.com/google/traceur-compiler/wiki/Options-for-Compiling
c.default_compilation_options.modules = :amd
c.default_compilation_options.source_map = true
