Hugs

Hugs is a small, portable Haskell interpreter written in C that can run on almost any machine. Hugs is best suited for use as a Haskell program development system: it features extremely fast source code interpretation, supports incremental interpretation, and offers the convenience of an interactive interpreter (allowing users to move between modules to test different parts of a program). However, as an interpreter, its runtime performance hardly matches that of programs like GHC, nhc98, or HBC. Hugs 98 complies with Haskell 98. It is available for all Unix platforms, including Linux, DOS, Windows 3.x, Win32 (Windows 95, Win32s, NT), and Macintoshes. It comes with numerous libraries, including a Win32 library, an external interface mechanism for easy interoperability with C, and the Windows version includes a graphical user interface called WinHugs. Explanations for some common Hugs error messages and their causes can be found on Simon Thompson's page.
