/prog/ - Haskell has better libraries than CL

_{They're standardized too!}

Too bad it's DEAD as fuck.

Compared to a language that hasn't been updated for at least 15 years?

Yes, and C++ has even more/better libraries. Is C++ better than Haskell? No.

I'd disagree that the C++ libs are better, however that isn't in the scope of this post. Haskell vs. Sepples library-wise doesn't compare to Haskell vs. CL library-wise. CL's libs are just a non-standard pile of shit.

if only the Haskell libraries were used for anything

What does ``non-standard pile of shit'' mean? A lot of them have standards behind them or proper documentation. There are some bad libs, but there are enough good ones. I'm mostly fine with CL's library situation. I almost always find what I need and the code that I write is portable.

Indeed. Sad world.

I never knew /prog/ was an abbreviation for BULLSHIT

Because it's not. It's ``ABSTRACT BULLSHITE'', that you will ^never _comprehend.

Lisp



yoba N -> keep {N->all N%?!=0 [2..N/2]} [1..N] | sum

Haskell



import Control.Monad

import Control.Monad.ST

 

import Data.Array.ST

 

import Data.STRef

 

yoba maxPr = runST $ do sum   <- newSTRef  0

                        items <- newArray (2, maxPr) True :: ST s (STUArray s Integer Bool)

 

                        let limit = truncate $ sqrt $ fromIntegral maxPr

 

                        let incSum = (modifySTRef sum) . (+)

 

 

                        [2.. limit] `forM_` \index -> readArray items index

                            >>= when `flip` do forM_ [index * index, index * index + index .. maxPr] $ writeArray items `flip` False

 

                        [2.. maxPr] `forM_` \index -> readArray items index

                            >>= when `flip` do incSum index

 

                        readSTRef sum
