honza.kuzel/Haskell.Preludev1.0.0

The well-tested analogy for part of very usefull Haskell's basic functions library created in C#. Implemented: Abs Map Foldr Foldr1 Foldl Foldl1 Head Tail All And Or Chr Ord Break Span Concat ConcatMap Const Not DigitToInt Drop Even DropWhile Elem Any Filter Flip Fst Snd GCD ID Init Iterate Last LCM Length Lines Max Min Maximum Minimum NotElem Null Odd Repeat Replicate Take Reverse Show Sort SplitAt TakeWhile ToUpper IsUpper ToLower IsLower Unlines Until Unwords Words Zip ZipWith Atan Compare Cos Div Error Exp Floor FromIntegral IsAlpha IsDigit IsSpace Log Mod Product Rem Quot Sin Sum Truncate Implemented like: Extensions - the most significant param is extended and, of course, the first one (usually the enumerator of something) Changes: Error does not return a type Compare returns same value as CompareTo (-1, 0, 1) instead Eq enum (LT, EQ, GT) FromIntegral just casting int to double Print and PutStr have additional parameter StringBuilder which return after write Implementation details: The mathematical functions like sin, cos, .. are easyilly implemented using System.Math and was not tested The class use nothing more then System library and Ienumerable interface The numerict functions are supported only for int and double (Sum, Product) Not implemented: pred succ undefined operators - it is not posible define or redefine properly (you have to use standard C# operators) Use only these functions can be useful for production code or like exercise for work with functions and composition of functions, but a lot of from prelude has been already implemented in System.Linq.
