Hugs

Hugs (Haskell User's Gofer System) (also Hugs 98) is a bytecode interpreter for the functional programming language Haskell. Hugs is the successor to Gofer, and was originally derived from Gofer version 2.30b.cite web|url=http://cvs.haskell.org/Hugs/pages/users_guide/faq.html|title=Frequently Asked Questions about Hugs|accessdate=2006-08-04] It comes with a simple graphics library. As a complete Haskell implementation that is portable and simple to install, Hugs is often recommended for new Haskell users.

Hugs deviates from the Haskell 98 specificationcite web|url=http://haskell.org/onlinereport/|title=Haskell 98 Language and Libraries: The Revised Report|accessdate=2006-08-03|year=2002|month=December|author=Simon Peyton Jones (editor)|authorlink=Simon Peyton Jones] in several minor ways. [cite web|url=http://cvs.haskell.org/Hugs/pages/users_guide/haskell98.html#BUGS-HASKELL98|title=Haskell 98 non-compliance|work=The Hugs 98 User's Guide|accessdate=2006-08-04] For example, Hugs does not support mutually recursive modules.

The Hugs prompt (a Haskell REPL) accepts expressions for evaluation, but not module, type or function definitions. Hugs can load Haskell modules at start-up. [cite web|url=http://cvs.haskell.org/Hugs/pages/users_guide/module-commands.html
