GHC plays fast and looose with the Haskell 2010 prelude. Two examples: GHC drops Eq from the context of class Num. GHC introduces class Applicative. You will stumble over such discrepancies if you try to write or read GHC code as if it were Haskell 2010. Doug >From simonpj(a)microsoft.com Fri Jul 6 10:46:41 2018 > | ghc/ghci. It's lightweight and its language is properly documented (in the > | Haskell 98 report), neither of which can be said of ghc. > I think that’s a little unfair to GHC 😊. If you don't give any language extension flags you get Haskell 98 -- or nowadays Haskell 2010. > Simon

needing some Hugs
by Anthony Clayden 05 Jul '18

> > Is anybody still listening here? I see the Hugs source distro is still around - vintage 2006, and there's somebody curated it on github. I'm particularly looking for a version with TRex, but the github-curated version doesn't seem to include that(?) Can anybody comment on how easy it is to compile Hugs (on Windows), compared to compiling GHC? The instructions for Hugs make out it's reasonably easy, whereas the instructions for GHC seem to be fraught with gotchas. But perhaps Hugs has as many gotchas, just not documented(?) My impression from discussion forums when Hugs was still active, is that Hugs source was easier to hack if you wanted to experiment with changes to the language(?) What seems sad these days is that GHC is so monstrous and formidable, hardly anybody builds experimental extensions to Haskell. Thank you AntC

Re: [Hugs-users] installation of haskell stopped software cure 14.09 from working through its own glut32.dll

Hi Stefan, What software were you installing? Note that both Yhc and Hugs are mostly dead. The recommended way to install Haskell is via the Haskell Platform https://www.haskell.org/platform/ Thanks, Neil On Saturday, 18 October 2014, Stefan Ludwig <dipl-ing.ludwig(a)web.de> wrote: > Hi, > > a software that claims hereself as purely functional should not cause > malfunctions in other software!!! > > after installing haskell it took me some hours to find out that haskells > glut32.dll created a conflict > with cura 14.09 and older versions > > DAMM IT!!! > > The haskell community is claiming to be high productive and secure. > I can't share this !! > > Hope the receiver of this message is forwarding to the responsible person > > best regards > > Stefan > >

Why does putStrln "" produce two newlines in hugs, but one in ghci? Doug McIlroy

[ann] hugs on JVM
by Szymon Jachim 03 Apr '11

03 Apr '11

Just a small announcement about a nice toy that I've put online. Hugs 98 compiled to a Java class: http://code.google.com/p/jhugs/ Next step will be to run it on a Android based phone. Another nice thing thing would be to create a JSR 223 ScriptEngine. This would allow to script Java existing business classes with Haskell. Szymon

the standard function enumFrom
by Paqui Lucio 25 Oct '10

25 Oct '10

Hi, Given the following enumerated type (as an example) data P = A | B | C | D | E deriving (Show,Enum) and the Prelude definition: enumFrom x = map toEnum [ fromEnum x ..] I guess that the two expressions 1) (map toEnum [ fromEnum A ..]) :: [P] 2) enumFrom A should produces the same result, say [A,B,C,D,E] :: [P] However, the expression 1) produces an error as a consequence of trying to apply toEnum to the number 5. ¿Why the expression 2) doesn't not produce the same error? ¿Does Hugs not apply the definition in the Prelude for evaluating the expression 2)? There should be something that I'm missing in this computation. Some hints?
