Groovy And Groovy++,Are they different?

Question

i recently came to know that groovy++ have been released, what is the major difference is in Groovy and Groovy++?

Answer 1

From the groovy++ page http://code.google.com/p/groovypptest/

Groovy++ is statically typed extension of Groovy programming language. Additionally to all goodies of standard Groovy it adds a lot of functionality

• compile time checking of code
• as fast as Java performance of compiled code
• easy mixing of statically and dynamically typed code
• very powerful type inference
• tail recursion traits (interfaces with default implementation)
• extension methods (compile time categories)
• standard library of utilities for functional programming, concurrency and distributed computing (early prototype stage)

Answer 2

Groovy++ is an extension to the core Groovy 1.x language. You drop the GroovyPP.jar file into the Groovy library directory, add @Typed in front of the package keyword in your code, then run your code just as you would in core Groovy. It infers the types, AND runs faster!

Answer 3

There is a good article on what Groovy++ brings to Groovy here. It includes benchmark results, so you can see the performance difference vs. Groovy and straight Java.
