2. I am looking for a parser, but I don't know Haskell parsers. Is Parsec a good choice? Parsec is definitely a good choice, but beware that it parses the whole input before returning, thus it may consume a huge batch of memory. As CSV is a line oriented format, you should make your

Hi Michal, Maybe you should use accumArray to get your histogram. accumArray :: Ix a = (b - c - b) - b - (a,a) - [(a,c)] - Array a b This functions takes a function to combine elements with the same index a, an initial element b, and the range of indices (a,a). We can now write a

Hi all, There exist a really neat solution to this. I think that it is pioneered by Doaitse Swierstra and Luc Duponcheel in their parser combinators: http://www.cs.uu.nl/~doaitse/Papers/1996/LL1.pdf I'm trying out some combinatorial parsers, and I ran into a slightly inelegant
