루비를 하스켈 처럼 짜기
수, 2006-10-25 17:03 — wookay
루비로 작성하는 하스칼 스타일 코드를
만들어 보고 있습니다
아래는 전혀 루비스럽지 않은 코드처럼 보이지만
잘 돌아갑니다.
$DEBUG = true
require 'haskell_style'
length [1,2,3]
length ['a','b','c']
length [[1],[],[2,3,4]]
length "def"
head [1,2,5]
tail ['a','b','c']
areaRect 5, 8
areaSquare 6
simple 3, 9, 5
multSumByFive 1, 2
fold :+, 0, [1, 2, 3]
fold :*, 1, [1, 2, 3]
listSum 1,2
reverse 1,2,5
zip [1,2,3], [4,5,6]
take 3, [0, 1..5]
drop 3, [0, 1..5]
map :abs, [-1,-3,4,-12]
map :reverse, ["abc","cda","1234"]
map :odd?, 1..9
map lambda {|x| 3*x.to_f + x/4.to_f }, [1,2,3,4]
haskell_style.rb는 구글 닥스에 올려두었습니다

사실 이거는 대충 흉내만 내는 정도이고
루비 쪽에는 Prelude Ruby란게 있으니까 참고하시길 바랍니다
A library of Haskell-style operations in Ruby with the goal of enabling higher-order functions and monads.

이상 순수하지 않은 함수형 언어 루비 였습니다 ^^:;
