dart2es6

The Dart to ECMAScript 6 transpiler

For design doc & TODO's, see wiki page

Usage

Get dependencies with pub get then run:

./dart2es6 input_path.dart -o output_path.js

See --help for more options.

Example: Transpiling Angular change detection

AngularDart's change detection library is included in the change_detection folder as an example. The folder included here has been modified from the original with some unsupported code removed.

To transpile this example:

cd change_detection
./transpile

The output will be located in change_detection/out

Uncomment line in change_detection/transpile to transpile change detection tests as well.

Currently, change detection and its tests transpile incorrectly since some code are not supported. See design doc for more info.

Running unit tests

Install dependencies:

• Install node and npm
• Install traceur: npm install -g traceur

Then run unit tests:

mkdir -p test/out/preprocessor test/out/traceur test/out/transpiler
dart -c test/test_runner.dart

Problems?

Check environment is set correctly. See scripts/travis/setup.sh and scripts/travis/build.sh.
