Eclipse Advanced Scripting Environment (EASE)

EASE is a scripting environment for Eclipse.

It allows to create, maintain and execute script code in the context of the running Eclipse instance. Therefore such scripts may manipulate and extend the IDE itself. Loadable script modules allow to simplify usage of native Java objects and can be extended with application specific methods.

Scripts may not only automate UI tasks, they can also be integrated into toolbars and menus dynamically. This allows to customize the IDE with pure script code.

Various script engines are available, like Rhino (JavaScript), Jython/Py4J (Python) or Groovy. The extensible framework allows to add any kind of language, you could even embed your own command shell.
