Question

Groovy vs BeanShell

Asked by: rstaveley

I'm relatively new to using BeanShell, which I found was invaluable for writing quick'n'dirty scripts for a Lucene project. Groovy in scripting mode looks on the surface to be a replacement for BeanShell, but it compiles to byte code, which I guess means that it ought to be possible to make quick'n'dirty scripts a lot quicker because they do less work with Java reflection.

Is there a case for continuing with BeanShell or is Groovy simply "better"?

There is also (just to complicate things further) JRuby

http://jruby.codehaus.org/

Which has just got a compiler as well, so Ruby can be compiled to JVM bytecode

Personally, I currently use Groovy

From mayankeagle's first link:

> BeanShell the scripting language for Java and Groovy the dynamic, agile language for the JVM.

Concisely put and now I understand. It is funny that the definition caused so much upset in the comments at the bottom of the article.

From mayankeagle's second link:

> It's powerful. The ability to apply closures (unnamed blocks of code) to whole collections using commnads like Collection.each, Table.eachRow, and File.eachLine let you get a lot done in a few lines of code.

That *is* an attractive feature. I'm a big fan of inlining code to localise it so you don't have to keep flipping between modules. However, this mostly puts the spotlight on Sun's lack of foresight to provide support for closures in native Java... all eyes on Dolphin.

I'm interested to hear that TimYates is a Groovy user. I'll be lurking in this TA, hoping to get a sense of what it is like as a user, but only really out of idle curiosity. I think I'll be hanging in with BeanShell for my purposes, because my projects aren't naturally agile... and nor am I :-)

Thanks to both of you!
