Kinet is a library for C# that provides useful data structures and algorithms for general purpose programming. It is somewhat inspired by the Functional Java project and the Haskell programming language.

Compilable Usage Examples

• Generating lazy immutable ranges using Enumerators

• Fibonacci using lazy evaluation

• LINQ comprehensions over Func using extension methods

• LINQ comprehensions over an immutable List

• Many Monoids and their operations

The List monad using LINQ

var a = List<int>.list(1, 3, 5, 5, 100, 671392);   
var b = from i in a select i * 10;
var c = from i in a
        from j in List<string>.list("a", "b", "c")
        select Tuple2<int, string>.tuple2(i, j);
var d = from i in c
        where i.a > 10 || i.b == "b"
        select i;

var si = Show<int>.AnyShow();
var se = si.IEnumerableShow;
var ste = si.Tuple2Show<string>(Show<string>.AnyShow()).IEnumerableShow;
   
/*
[1,3,5,5,100,671392]
[10,30,50,50,1000,6713920]
[(1,a),(1,b),(1,c),(3,a),(3,b),(3,c),(5,a),(5,b),(5,c),(5,a),(5,b),(5,c),(100,a),(100,b),(100,c),(671392,a),(671392,b),(671392,c)]
[(1,b),(3,b),(5,b),(5,b),(100,a),(100,b),(100,c),(671392,a),(671392,b),(671392,c)]
*/ 
se.Println(a);
se.Println(b);
ste.Println(c);
ste.Println(d);

The Func monad using LINQ

Func<int, bool> t = n => n > 10;
Func<int, string> u = n => (n - 1).ToString();
Func<int, string> v = n => (n * 5).ToString();

var a = from tt in t
        from uu in u
        from vv in v
        select tt ? uu : vv;
var b = from k in List<int>.list(9, 10, 11, 5, 20)
        select a(k);

var s = Show<string>.AnyShow().IEnumerableShow;
// [45,50,10,25,19]
s.Println(b);
