husk Scheme

husk is a dialect of Scheme written in Haskell that adheres to the R5RS standard. Advanced R5RS features are provided including continuations, hygienic macros, and a full numeric tower.

husk may be used as either a stand-alone interpreter or as an extension language within a larger Haskell application. By closely following the R5RS standard, the intent is to develop a Scheme that is as compatible as possible with other R5RS Schemes. husk is mature enough for use in production applications, however it is not optimized for performance-critical applications.

Scheme is one of two main dialects of Lisp. Scheme follows a minimalist design philosophy: the core language consists of a small number of fundamental forms which may be used to implement other built-in forms. Scheme is an excellent language for writing small, elegant programs, and may also be used to write scripts or embed scripting functionality within a larger application.


The Glasgow Haskell Compiler (GHC) is required to build, install, and run husk. All recent versions of GHC are supported, including 6.10, 7.0, 7.2, and 7.4. The easiest way to get GHC is via the Haskell Platform.

husk has been tested on Windows, Linux, and FreeBSD.

husk may be installed using cabal:

cabal update
cabal install husk-scheme
