/prog/ - how do i shot arrow???

Name: Anonymous 2007-02-03 12:27

*** ??? &&&

Nah, just kidding, I kinda get them.

liftA2 :: (Arrow a) => (b -> c -> d) -> a e b -> a e c -> a e d

liftA2 p f g = f &&& g >>> (arr . uncurry) p



split :: Eq a => a -> [a] -> [[a]]

split _ [] = []

split d l  =

  ((dropWhile (== d)) ^>> (liftA2 (:) (takeArrow d) (dropArrow d >>^ (split d)))) l

  where

  takeArrow d = arr . takeWhile $ (/= d)

  dropArrow d = arr . dropWhile $ (/= d)

I wonder if this is what they are supposed to be used for though ;) And I realized that functions are actually arrows already after writing this :/

and what happens in one week, when no one understands what kind of crap you wrote? and you forgot too why it was written?

The autistic one would be you, actually. It should be pretty obvious that the op is just experimenting.

show me one line of Haskell which is not an experiment at someone's showing his e-penis...

Experimenting? What I posted in >>1 is production code! And I can still read it, hours after I wrote it.

Do a barrel roll!

import Control.Arrow

split :: Eq a => a -> [a] -> [[a]]
split d =
    barrelRoll ((fmap fst . takeWhile (/=([],[])) . snd) &&&
      (uncurry (:) . (uncurry (***)
      ((id &&& (fmap . (flip (.) snd)))
   ((break (== d)) . (dropWhile (== d)))))))
    where
      barrelRoll = loop

I would fire you from my team if you wrote this kind of crap as "production" code.

Well, you Sir, are the winnar :X

I've got to study for a couple days to get this.

So tell me, what's the real point of having arrows? It seems to me like it's just an overcomplicated and over-syntax'd wrapper to make functions look like monads. Which is kinda something we already have a special syntax for, right?

Maybe I'm just not getting it. On the other hand, I haven't seen any arrow instances that weren't functions, either!

They can do everything monads can do, and more ;) (I don't really know what monads can do though)

Arrows are useful for showing directions.

After class I start following the her in a totally not-stalker-y way. She somehow eludes me, and I end up at some festival thing where I play some scavenger hunt game which consisted of finding candy in tall grass. And then I woke up.

i'm going to guess the bugs in the expansion extend to the routes, too. this route is suppossed to be really easy (it's similar to the route in "The Dungeon of Dreams and Magic" that had nothing but Nazrin's in it), yet as far as i can tell it never ends and frequently throws Monster Rooms filled with high level monsters.
