#70: Uninformative error in do binding --------------------+------------------------------------------------------- Reporter: neil | Owner: nobody Type: defect | Status: new Priority: major | Milestone: Component: hugs | Version: 200609 Keywords: | --------------------+------------------------------------------------------- Given the program: {{{ main = do [] <- return "test" print "test" > main Program error: user error (match fails) }}} It would be nice if the message at least mentioned "do" somewhere. The only way of figuring out what going wrong in a big program is to flip to GHC. -- Ticket URL: <http://hackage.haskell.org/trac/hugs/ticket/70> Hugs <http://www.haskell.org/hugs/> Hugs 98, an interpreter for Haskell

[Hugs] #69: Pattern match error can be arbitrarily long

#69: Pattern match error can be arbitrarily long --------------------+------------------------------------------------------- Reporter: neil | Owner: nobody Type: defect | Status: new Priority: major | Milestone: Component: hugs | Version: 200609 Keywords: | --------------------+------------------------------------------------------- Given the program: test n = length val `seq` f val where val = replicate n (toEnum 12) f "" = "" > test 3 Program error: pattern match failure: f [toEnum 12,toEnum 12,toEnum 12] Unfortunately, as you bump up n (try 10,000) Hugs spits and more and more information - when the most important bit of this message is "f" - which you end up loosing. I suggest truncating pattern match errors at (say) 500 characters, or perhaps 500 characters per argument. -- Ticket URL: <http://hackage.haskell.org/trac/hugs/ticket/69> Hugs <http://www.haskell.org/hugs/> Hugs 98, an interpreter for Haskell

#66: WinHugs should have a multi-line box for listing include paths ---------------------+------------------------------------------------------ Reporter: neil | Owner: neil Type: defect | Status: new Priority: minor | Milestone: Component: winhugs | Version: 200609 Keywords: | ---------------------+------------------------------------------------------ Currently, with WinHugs you have to specify all include paths in a single box which you can't see the end of. This is bad from a user interface perspective, and very hard to use correctly. -- Ticket URL: <http://hackage.haskell.org/trac/hugs/ticket/66> Hugs <http://www.haskell.org/hugs/> Hugs 98, an interpreter for Haskell
