Ynot is a free and open-source scripting language that allows you to easily read and write scripts.
You won't need to compile anymore. Also, you can run Ynot on all major platforms.
Furthermore, the scripts can directly use all the Java SE API (swing, sound, etc).
Ynot is written in Java and built around the RDC principle.
Detailed instructions on how to install and use the Ynot utility on your Mac are available HERE.
Ynot is cross-platform and it works on Mac OS X, Windows and Linux. Binaries for the Windows and Linux platforms are available on the project's homepage.
