This question here is related to Haskell Input Return Tuple I wonder how we can passes the input from monad IO to another function in order to do some computation.
I\'m reading the book Real-world functional programming by Tomas Petricek and Jon Skeet and I\'m having a hard time digesting the section on computation expressions1) (aka monads).
The following simple function applies a given monadic function iteratively until it hits a Nothing, at which point it returns the last non-Nothing value. It does what I need, and I understand how it w
I\'m working on a codebase ported from Objective C to Java. There are several usages of method chaining without nullchecks
How can I issue multiple calls to SDL.pollEvent :: IO Event until the output is SDL.NoEvent and collect all the results into a list?
I don\'t understand the exact algebra and theory behind Haskell\'s monads.However, when I think about functional programming in general I get the impression that state would be modelled by taking an i
First of all, it\'sgreat.However, I came across a situation where my benchmarks turned up weird results.I am new to Haskell, and this is first time I\'ve gotten my hands dirty with mutable arrays and
In my area of business - back office IT for a financial institution - it is very common for a software component to carry a global configuration around, to log its progress, to have some kind of error

I\'m trying to create a monad transformer for a future project, but unfortunately, my implementation of the Monad typeclasse\'s (>>=) function doesn\'t work.
