Partial Application and Currying Questions
I am slowly becoming a functional programming weenie -- really cool stuff. A discussion came up on groovy-dev about how I implemented currying on closures in groovy -- it was pointed out that what I really did was partial-application.
A quick google search sort of reinforced this, but I am not sure the difference, so here is a shameless plea for explanation. Here is my current understanding (in gauche scheme):
(use rfc.http)
(use srfi-11)
(define http-get-body
(lambda (host file)
(let-values (
((response head body) (http-get host file)))
body)))
(define with-http-body
(lambda (host file func)
(func (http-get-body host file))))
(define with-ojb
(lambda (func)
(with-http-body "db.apache.org" "/ojb/index.html" func)))
(with-ojb
(lambda (body)
(display body)))
I think with-ojb is partial application as it provides two of the three arguments required by with-http-body and returns a function which takes the last. If that is the case, what is currying? Until today I thought that was currying. The wikipedia seems to say this is currying, but it seems to fit exactly the haskell definition of partial application -- and the examples on the wikipedia look very different.
Help?
