Hugs is obsolete and unmaintained, so you are unlikely to find that anywhere.

ghc compiles, where Hugs is an interpreter, so it does not come with Prelude source.

Thanks for that. But I think that HUGS also has a Prelude.hs . After doing a bit of searching, I found it and posting it for reference : Prelude.hs is found in /USR/LIB/HUGS/PACKAGES/BASE/PRELUDE.HS for ubuntu and debian based distros. _____________________ Yours Truly, Debdut Karmakar Links: ------ [1] http://lambda.haskell.org/platform/doc/current/ghc-doc/libraries/haskell2010...

The Hugs Prelude is/was nice and simple -- self-contained, no compiler pragmas -- which is why you're encouraged to read it in the Haskell Road book...I think the idea is to convey that the student could have written it themselves, including things that are primitive in other languages, with no magic required. http://ogi.altocumulus.org/~hallgren/Programatica/tools/hi/libs/HugsLibrarie...
