The Nottingham and Yale Haskell interpreter and programming environment. Nottingham and Yale are pleased to announce a new release of Hugs, a Haskell interpreter and programming environment for developing cool Haskell programs. Sources and binaries are freely available by anonymous FTP and on the World-Wide Web. This release is largely conformant with Haskell 1.4, including monad and record syntax, newtypes, strictness annotations, and modules. In addition, it comes packaged with the libraries defined in the most recent version of the Haskell Library Report and with extension libraries which are compatible with GHC 3.0. Hugs is best used as a Haskell program development system: it boasts extremely fast compilation, supports incremental compilation, and has the convenience of an interactive interpreter (within which one can move from module to module to test different portions of a program). However, being an interpreter, it does not nearly match the run-time performance of, for example, GHC or HBC. We keep the latest information about Hugs (including a known bug list and porting information) at http://www.haskell.org/hugs.
