Hugs

From Wikipedia, the free encyclopedia

This article is about the Haskell interpreter. For the affectionate physical gesture, see Hug.

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.[1] 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 specification[2] in several minor ways.[3] 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.[4]
