afifmohammed / FreeIOMonad.cs

Created June 14, 2018 13:32 — forked from dadhi/FreeIOMonad.cs

Example of Free IO monad in pure C# with separated re-usable monad implementation

	/*
	Modified from the original https://gist.github.com/louthy/524fbe8965d3a2aae1b576cdd8e971e4

	- removed dependency on [language-ext](https://github.com/louthy/language-ext)
	- separated monadic boilerplate, so you may concentrate on describing the operations and interpretation of the program
	- removed `IO<A>.Faulted` to simplify the examples. It can be added back in straightforward manner.

This is an example of using the Reader Monad for Dependency Injection using LINQ in C#. I learned about this from Tony Morris and Rúnar Bjarnason's video here: http://www.youtube.com/watch?v=ECPGTUa1WAI To figure out the (slightly weird) SelectMany peculiarities I found http://mikehadlow.blogspot.com/2011/01/monads-in-c-4-linq-loves-monads.html

	public static class ReaderMonadExt
	{
	public static Func<T, C> SelectMany<T, A, B, C>(this Func<T, A> t_a, Func<A, Func<T, B>> a_t_b, Func<A, B, C> ab_c)
	{
	return t =>
	{
	var a = t_a(t);
	return ab_c(a, a_t_b(a)(t));
	};
	}

	C# does not have proper sum types. They must be emulated.

	This data type is one of 4 possible values:
	- WriteOut, being a pair of a string and A
	- WriteErr, being a pair of a string and A
	- readLine, being a function from string to A
