Scripting language like Groovy (or JRuby) is an ideal choice for Java developer to do quick prototyping. The biggest benefit of Eclipse support for Groovy plug-in development is that while changing the plug-in on-the-fly there's no need to start a separate Eclipse instance or restart the IDE when something was changed in the code. This would rapidly improve the speed of lightweight plug-in development.
This project aims to add ability to write plugins in JVM-based scripting language, like Groovy and JRuby. But it could be a starting point for any other JVM scripting language, like BeanShell or Jython.
The engine, codename yummy, isn't very advanced piece but it is sufficient to run a Groovy/JRuby script.
The dependencies for any specific language PDE implementation are:
- <language>.jar, e.g. groovy-all.jar
- <language>-engine.jar, e.g. groovy-engine.jar
- yummy.jar, i.e. the plug-in for any specific language will use the engine to run the scripts executed by <language>-engine.jar at the end.
The dependencies will be provided via "add nature" functionality.
Other dependencies should be attached with the scriptable plug-in, which will be developed by a user.
Plug-In Architecture Notes. When starting the "scriptable" plug-in, the extensions defined in plugin.xml should be processed by a custom handler, that will override the standardized extension processing.
The main results to be reached:
- An Eclipse extension/plug-in to (re)load (Groovy/JRuby) scripts on the fly.
- Command line console support to modify and change the program behavior interactively. This could look like in case Apache Derby ij plug-in
