Applications and libraries/Compilers and interpreters

Haskell, with its support for pattern matching on data structures, generic structure traversals, and expressive type system, is popular for implementing compilers and interpreters. Here's a selection of compilers and interpreters implemented in Haskell.

Large languages

Haskell

GHC

GHC, The Glasgow Haskell Compiler, is written in Haskell

Yhc

Yhc, The York Haskell Compiler, is written in Haskell

Jhc

Jhc is a Haskell compiler which aims to produce the most efficient programs possible via whole program analysis

nhc98

A compiler for Haskell 98, written in Haskell

Ehc

The purpose of the EHC project is to provide a description of a Haskell compiler which is as understandable as possible so it can be used for education as well as research.

pH

A parallel version of Haskell from MIT.

Helium

Helium

A Haskell subset for educational purposes

Generic Haskell

Generic Haskell

An extension of Haskell that supports generic programming

Data Field Haskell

Data Field Haskell

A dialect of the functional programming language Haskell that provides an instance of data fields

Eden

Eden

A Haskell dialect for parallel programming

Chameleon

Chameleon

A Haskell-style language which implements the ideas described in a ``A Theory of Overloading``

CHR (Constraint Handling Rules)

CHR (ps)

A concurrent committed-choice constraint logic programming language, implemented using GHC's software transactional memory.

Perl

Pugs

Pugs is an implementation of Perl 6, written in Haskell. It aims to implement the full Perl6 specification.

Ruby

RType

RType is a Ruby interpreter written in Haskell

Scheme

Write Yourself a Scheme in 48 Hours

A small Scheme interpreter

Lisp

A Lisp Interpreter In Haskell

A small lisp interpreter written in Haskell

Emacs Lisp

Helisp

The beginnings of an Emacs lisp compiler/interpreter.

Epigram

Epigram

Epigram is a prototype dependently typed functional programming language

Curry

The Münster Curry Compiler

A native code compiler for the declarative multi-paradigm language Curry, written in Haskell

Bluespec

Bluespec

A compiler for a hardware description language translating a Haskell-like (but with System Verilog syntax these days) language to Verilog.

Cayenne

Cayenne

A compiler for a Haskell-like language with depedent types.

Agda

Agda

A Cayenne-like programming language and proof assistant.

PolyP

PolyP

A polytypic programming language

Forth

Harrorth

Harrorth, a Forth interpreter

Eiffel

Dynamic binding in Eiffel

A model of dynamic binding in ECMA Eiffel, in Haskell

Crouton

Crouton

Crouton is a small but fairly complete functional programming language for querying and transforming parsed manuscripts, such as the PPCME. It is intended as an alternative to Corpus Search, based on a different philosophy. It is written in (and largely based on) the very nice functional programming language Haskell using the Parsec library

Small languages

Baskell

Baskell

An interpreter for a small functional programming language. Supports strict and non-strict evaluation, and type inference. Useful for teaching purposes.

Unlambda

Unlambda.hs

An implementation of unlambda in Haskell

BF

BF.hs

An implementation of BF in Haskell

Lambda calculus

4 lambda calculus implementations

With code, by Lennart Augustsson.

LMEngine

An implementation of the untyped lambda calculus

Debuggers

Debussy

A declarative debugger for OBJ-like languages
