jaskell - Java Haskell pure functional programming language.
- Description:
There are already many cool scripting languages in jvm.
Jython, JRuby, Groovy etc. They are all excellent and very
practical scripting languages. Why yet another scripting
language?
Well. Jaskell is designed not to be a better language, but
a different one.
1. Most of the current scripting languages are Object-Oriented.
Though they more or less have functional tastes (Ruby's
sexy closure, for example), the heart of them are still
Object-Oriented. One of the most important essenses of
functional programming (combinators) is yet to be brought
into Java.
2. Jaskell brings with it higher order function, function
currying, pattern match and monadic combinator support.
3. Monadic combinator is ideal for designing Domain Specifi
Language. It is relatively easy to tailor Jaskell runtime
to make domain specific syntax look like simple atomic
statements. See Neptune for a real example.
4. Jaskell bridges nicely between functional interpreter and
Java. In fact, Jaskell is nothing but a Java library that
passes Java objects in and out of the interpreter.
