cassowary-java

Cassowary-java is a pure Java implementation of the Cassowary constraint-solving algorithm.

Cassowary is the algorithm that forms the core of the OS X and iOS visual layout mechanism.

Quickstart

The easiest way to use Cassowary in you Java project is using Gradle. Just add the JCentre Maven repository url to your project's build.gradle:

repositories {
    jcenter()
}

Then add the Cassowary dependency:

dependencies {
    compile "org.pybee:cassowary:0.0.1"
}

Building cassowary-java

Gradle can also be used to manage the build and release of Cassowary-java. To build the Cassowary release jar file, run:

./gradlew build

This will also run the test suite. Assuming everything works, you can publish to a Maven repository. Make sure you have a gradle.properties file in the root directory of the project; it should contain the following:

bintray_user=<your bintray username>
bintray_api_key=<your bintray API key>

If this file is correct, you can publish using:

./gradlew bintrayUpload

Community

Cassowary-java is part of the BeeWare suite. You can talk to the community through:

• @pybeeware on Twitter
• The BeeWare Users Mailing list, for questions about how to use the BeeWare suite.
• The BeeWare Developers Mailing list, for discussing the development of new features in the BeeWare suite, and ideas for new tools for the suite.

The Cassowary community also has a mailing list; it provides more general assistance regarding the Cassowary algorithm itself.

Acknowledgements

The Cassowary implementation is a fork of the original Java library published by Greg J. Badros.

The Cassowary code has been updated to be compliant with Java 1.4+, removes and simplifies certain features, and applies a consistent coding style guide.
