Contributing to Sky Engine

Getting the code

To get the code:

• Fork https://github.com/domokit/sky_engine into your own GitHub account.
• Download depot_tools and make sure it is in your path.
• Create a .gclient file in an empty directory with the following contents:

solutions = [
  {
    "managed": False,
    "name": "src",
    "url": "git@github.com:<your_name_here>/sky_engine.git",
    "custom_deps": {},
    "deps_file": "DEPS",
    "safesync_url": "",
  },
]
target_os = ["android"]

• svn ls https://dart.googlecode.com/ and accept the certificate permanently.
• gclient sync
• cd src
• git remote add upstream git@github.com:domokit/sky_engine.git

Building the code

Currently we support building for an Android target and for a headless Linux target.

Android

• (Only the first time) ./build/install-build-deps-android.sh
• (Only the first time) ./tools/android/download_android_tools.py
• ./sky/tools/gn --android
• ninja -C out/android_Debug
• ./sky/tools/shelldb start out/android_Debug/ sky/sdk/example/hello_world/lib/main.dart

Linux

• (Only the first time) ./build/install-build-deps.sh
• ./sky/tools/gn
• ninja -C out/Debug
• ./out/Debug/sky_shell --package-root=out/Debug/gen/dart-pkg/packages sky/sdk/example/hello_world/lib/main.dart Note: Because Linux is headless, you won't see any UI. You can use print to generate console output or you can interact with the DartVM via observatory at http://localhost:8181/.

Contributing code

The Sky engine repository gladly accepts contributions via GitHub pull requests:

• git fetch upstream
• git checkout upstream/master -b name_of_your_branch
• Hack away
• git commit -a
• git push origin name_of_your_branch
• git pull-request (if you are using Hub) or go to https://github.com/<your_name_here>/sky_engine and click the “Compare & pull request” button

You must complete the Contributor License Agreement. You can do this online, and it only takes a minute. If you‘ve never submitted code before, you must add your (or your organization’s) name and contact info to the AUTHORS file.

Running tests

Tests are only supported on Linux currently.

• sky/tools/test_sky --debug
  • This runs the tests against //out/Debug. If you want to run against //out/Release, omit the --debug flag.
