I am developing a game and chose Happstack for the persistence part. I find it quite easy to use, i made a quick example for myself to understand it:
It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical andcannot be reasonably answered in its current form. For help clari
I know you suppose to think differently in Haskell, but c开发者_如何学Pythonan someone give me a quick answer on how to iterate over a list or nested list and print out a character based on the value
First attempt It\'s difficult to make this question pithy, but to provide a minimal example, suppose I have this type:
I\'ve written a merge sort in Haskell, it works when using numbers but not with words, and I thought it would. I just get \"Not in scope\" when using words and letters. What am I doing wrong?
i read on Andrew Birkett’s blog Applicative arrows for XML &&& return to pure that we could mix arrows and applicative functors.
I have a list of tuples that look like this. [ [(1,True),(2,True)] , [(3,False),(4,False),(5,False)] ]
It\'s possible to use the Scheme primitive read, which cons开发者_开发问答umes a stream of characters and outputs an s-expression (sexpr).
I have a question about recursive data structures in Haskell (language thatI\'m currently trying to learn).
I\'m working on a function that can count the number of operators used in an expression. My code is as follows:
