Dart2Js

Provide automated transcoding from Dart to Javascript.

Gemfile

gem 'ruby-dart2js'

DartJs will look for the dart2js binary in the following order:

1. DART2JS_SOURCE_PATH direct path to binary env DARTJS_SOURCE_PATH=/opt/dart-sdk/bin/dart2js
2. DART_SDK_HOME path to sdk env DART_SDK_HOME=/opt/dart-sdk
3. PATH looks for dart2js in your PATH-variable

dart_compiler = Dart2Js.new(file, options)
dart_compiler.compile
dart_compiler.get_js_content
dart_compiler.out_file

Initialization takes either dart-sourcecode directly or an instance of File as first argument and an options-hash as second argument. :dart2js_binary and :out_file may be provided with the options-hash.

dart_compiler.compile actually runs the dart2js command, the output of the run will be saved in @result and the final js stays in @out_file and may be read with dart_compiler.get_js_content.

With version 0.2.0 Dart2Js::compile now accepts a boolean argument for minifying, it's optional and true by default.
