How to I define the equivalent of this function (taken from learnyouahaskell) inside GHCi? import Data.List
Intro: While checking out snoyman\'s \"persistent\" library I found myself wanting ghci\'s (or another tool) assistance in figuring out stuff.
In test.hs, I have: doubleMe x = x + x In ghci, I type: Prelude> :l test [1 of 1] Compiling Main( test.hs, interpreted )
I\'m trying to compile this function from Learn You a Haskell for Great Good. removeNonUppercase st = [ c | c <- st, c `elem` [\'A\'..\'Z\']]
Is it possible to query the ghci for the type i开发者_Python百科t inferred for a function inside another function?This is a quick and ugly hack, but what I usually do is just use the function in the w
I\'ve been going through a Haskell tutorial recently and noticed this behaviour when trying some simple Haskell expressions in the interactive ghci shell:
I am trying to write a prop that changes a Sudoku and then checks if it\'s still valid. However, I am not sure how to use the \"oneof\"-function properly. Can you give me some hints, please?
One way to calculate 2^8 in haskell is by writing product(replicate 8 2) When trying to create a function for this, defined as follows...
I am new to Haskell, using Ghci. I have a function, called three, that I want to write as let three =\\x->(\\y->(x(x(x y))))
