Hugs 98 +provides an almost complete implementation of Haskell 98, including: - 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. +* Lazy evaluation, higher order functions, and pattern matching. +* A wide range of built-in types, from characters to bignums, and lists + to functions, with comprehensive facilities for defining new datatypes + and type synonyms. +* An advanced polymorphic type system with type and constructor class + overloading. +* All of the features of the Haskell 98 expression and pattern syntax + including lambda, case, conditional and let expressions, list + comprehensions, do-notation, operator sections, and wildcard, + irrefutable and `as' patterns. +* An implementation of the Haskell 98 primitives for monadic I/O, with + support for simple interactive programs, access to text files, + handle-based I/O, and exception handling. +* An almost complete implementation of the Haskell module system. + Hugs 98 also supports a number of advanced and experimental extensions + including multi-parameter classes, extensible records, rank-2 + polymorphism, existentials, scoped type variables, and restricted + type synonyms. |
