FunctionEx

Provides function operator extensions for .NET platform. Including function composition, partial application and pipeline operators.

NOTE: This is not a full port of the functional programming paradigm, but rather aims to provide functional manipulation primitives for .NET delegates. All features are built around extending delegates and do not introduce any new abstractions.

Core Operators

Operator Functional Concept Example Usage Mathematical Logic
Compose Backward Composition f.Compose(g)(x) $f(g(x))$
Then Forward Composition f.Then(g)(x) $g(f(x))$
Invoke Partial Application f.Invoke(a, __, c) $f'(b) = f(a, b, c)$
Apply Pipe Operator x.Apply(f) $f(x)$
Do Tee Pipe Operator x.Do(log) $log(x), x$

Prelude

Recommended for global usability:

global using XNetEx.Functions;
global using static XNetEx.Functions.CoreFunctions;
global using static XNetEx.Functions.Placeholder;

Or in *.*proj files:

  <ItemGroup>
    <Using Include="XNetEx.Functions" />
    <Using Include="XNetEx.Functions.CoreFunctions" Static="true" />
    <Using Include="XNetEx.Functions.Placeholder" Static="true" />
  </ItemGroup>

Usage

// Function composition
//   Backward composition
var not = Not;
var equals = Equals<int>;
var notEquals = not.Compose(equals);
var neResult = notEquals(1, 2); // true
//   Forward composition
var parse = (Func<string, int>)int.Parse;
var parseThenToString = parse.Then(ToString<int>);
var convertResult = parseThenToString("123"); // "123"

// Partial application
var dict = new Dictionary<int, string>();
var dictAdd = dict.Add;
var reqValue = dictAdd.Invoke(7); // By omitting rest parameters
var reqKey = dictAdd.Invoke(__, "42"); // By a placeholder
reqValue.Invoke("7");
reqKey.Invoke(42);
// dict: { [7] = "7", [42] = "42" }

// Pipeline operators
var result = "123"
    .Do(Console.WriteLine) // Apply and pass through
    .Apply(int.Parse) // Apply and pass the return value
    .Apply(value => (value, 123)) // Prepare two values as a tuple
    .Apply(Equals<int>); // Unpack tuple into binary function
// result: true
