2018-03-15 · A lambda calculus interpreter in Haskell. A few days ago, I wrote an interpreter for a small imperative language in Haskell. Today I wrote an interpreter for one of the smallest functional languages: the lambda calculus. It’s small enough to show you the whole thing in one go. Here’s Main.hs:

Lambdakalkyl är ett formellt system som skapades för att undersöka funktioner och rekursion. Lambdakalkyl utvecklades på 1930-talet av Alonzo Church, men fick sitt genombrott först efter 1969 då Dana Scott tagit fram den första konsistenta matematiska modellen för lambdakalkyl. Formella teorier för semantik i programspråk som baserades på lambdakalkyl hade innan dess ansetts som defekta då inga konsistenta matematiska modeller fanns. Lambdakalkylen är den matematiska grunden lambda calculus noun + grammatik (computing theory) Any of a family of functionally complete algebraic systems in which lambda expressions are evaluated according to a fixed set of rules to produce values, which may themselves be lambda expressions.

Example The Lambda Calculus has been invented at roughly the same time as the Turing Machine (mid-1930ies), by Alonzo Church. Don’t be intimidated by the word “calculus”! It does not have any complicated formulae or operations.

The Lambda calculus is an abstract mathematical theory of computation, involving λ \lambda λ functions. The lambda calculus can be thought of as the theoretical foundation of …

Lambda calculus terms can be viewed as a kind of binary tree.

Another basic operation often assumed in the lambda calculus is eta reduction/expansion, which consists of identifying a function, f f with the lambda abstraction (λ x. f x) (\lambda x. f x) which does nothing other than apply f f to its argument. Lambda calculus was invented by the mathematician Alonzo Church in the 1930s, and is what is known as a ‘computational model’.
