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
Flapjax
- Flapjax
- Flapjax is a language for functional reactive programming of AJAX web applications, whose compiler (source) is 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
Javascript
- HJS
- HJS is a Javascript parser written in Haskell. Available from HackageDB.
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
QML, a functional quantum programming language
- QML: A Functional Quantum Programming Language project
- It is implemented in Haskell.
For online material on quantum computing in general, see Quantum Computation course held by John Preskill.
HQL - HHM's Quantified Lambda
- Hernan's Quantified Lambda
- a small functional language, whose expressions can involve the use of quantifier operators
Atom
- Atom
- Atom is a small HDL that compiles conditional term rewriting systems down to Verilog RTL.
AL (Assignment Language)
It is used for teaching purposes in at the Technical University of Vienna. An inerreter implemented in Haskell is described in ALI - an AL Interpreter implemented in Haskell written by Peter Robinson.
Debuggers
- Debussy
- A declarative debugger for OBJ-like languages
