Opal

Build Status

Opal is a ruby to javascript source-to-source compiler. It also has an implementation of the ruby corelib.

Opal is hosted on github, and there is a Freenode IRC channel at #opal. There is also a google group for opal.

Usage

See the website, http://opalrb.org.

Running tests

Build the runtime, tests and dependencies:

rake opal

Run tests using phantom.js runner:

rake test

Alternatively, after building, you can open spec/index.html in any web browser.

Code Overview

core

The core directory holds the opal runtime and corelib implemented in ruby and javascript. These are built using rake opal, as above.

lib

The lib directory holds the opal parser/compiler used to compile ruby into javascript. It is also built ready for the browser into opal-parser.js to allow compilation in any javascript environment.

spec

  • core contains rubyspecs that apply to opal.
  • language applicable specs from rubyspec for testing language semantics
  • opal tests for extra methods/features in opal not found in standard ruby
  • lib specs for opal lib (parser, erb_parser, grammar etc)
