Awesome! The samples now work. Thanks so much for your help. -deech On Fri, Nov 11, 2011 at 11:14 PM, wrote: > > > The reason I commented out the Data.HList.TypeEqO was because I > > couldn't find it. > > My apologies!

Re: [Haskell-cafe] Label macro expansion bug In HList.
Thanks for updating the Cabal file. The reason I commented out the Data.HList.TypeEqO was because I couldn't find it. I grepped the HList source tree for it and I found references to it only in the following places: ./Data/HList/RecordD.hs:import Data.HList.TypeEqO ./examples/TIPTransform.hs:import Data.HList.TypeEqO ./examples/MainGhcGeneric1.hs: module Data.HList.TypeEqO, ./examples/MainGhcGeneric1.hs:import Data.HList.TypeEqO ./examples/MainPatternMatch.hs:import Data.HList.TypeEqO ./examples/TIPTransformM.hs:import Data.HList.TypeEqO ./HList.cabal: Data.HList.HListPrelude, Data.HList.TypeEqO, I couldn't find it on Hoogle or Hayoo either. Am I missing something? -deech On Fri, Nov 11, 2011 at 10:25 PM, wrote: > > > I have verified that the issue with the "makeLabels" function goes away > if > > I install 7.0.4. > > I'm glad to hear that.

Quite likely the reason was the Data.HList.TypeEqO import that you have commented out. Data.HList.TypeEqO is really needed. I have pushed the changed HList.cabal.

Re: [Haskell-cafe] Label macro expansion bug In HList.
I have verified that the issue with the "makeLabels" function goes away if I install 7.0.4. I got an extremely large error (~ 5000 lines) when loading "OCamlTutorial.hs". When I've parsed through it, I'll post back. Sorry for the confusion. -deech On Fri, Nov 11, 2011 at 1:33 PM, aditya siram wrote: > I also have the same issue with OOHaskell after pulling from > http://code.haskell.org/OOHaskell.

Re: [Haskell-cafe] Label macro expansion bug In HList.
I also have the same issue with OOHaskell after pulling from http://code.haskell.org/OOHaskell. After loading GHCI I did: > :l ../samples/OCamlTutorial.hs ../samples/OCamlTutorial.hs:97:3: Multiple declarations of `foo' Declared at: ../samples/OCamlTutorial.hs:53:1 ../samples/OCamlTutorial.hs:97:3 Failed, modules loaded: OOHaskell, Dynamic, Print, DeepNarrow, Nominal, New. Also in the beginning I was unable to load lib/OOHaskell.hs into GHCI because it tried to import a module that was no-longer exported by HList "Data.HList.TypeEq0". When I commented out that line, it loaded fine into GHCI. -deech On Fri, Nov 11, 2011 at 1:20 PM, aditya siram wrote: > I just pulled the latest version of HList : > > darcs clone http://code.haskell.org/HList > > I compiled it with GHC 7.2.1 and I am still running into the same issue > the "makeLabels" function: > > runQ (makeLabels ["test1","test2"]) >>= putStrLn . pprint > > data Foo_0 deriving (Data.Typeable.Internal.Typeable) > foo_1 = Data.HList.FakePrelude.proxy :: Data.HList.FakePrelude.Proxy Foo_0 > data Foo_2 deriving (Data.Typeable.Internal.Typeable) > foo_3 = Data.HList.FakePrelude.proxy :: Data.HList.FakePrelude.Proxy Foo_2 > > Also the cabal file that is currently at the tip of the repository > includes some of the files that have been moved into the "obsolete" > directory.

Re: [Haskell-cafe] Label macro expansion bug In HList.
I just pulled the latest version of HList : > darcs clone http://code.haskell.org/HList I compiled it with GHC 7.2.1 and I am still running into the same issue the "makeLabels" function: > runQ (makeLabels ["test1","test2"]) >>= putStrLn . pprint data Foo_0 deriving (Data.Typeable.Internal.Typeable) foo_1 = Data.HList.FakePrelude.proxy :: Data.HList.FakePrelude.Proxy Foo_0 data Foo_2 deriving (Data.Typeable.Internal.Typeable) foo_3 = Data.HList.FakePrelude.proxy :: Data.HList.FakePrelude.Proxy Foo_2 Also the cabal file that is currently at the tip of the repository includes some of the files that have been moved into the "obsolete" directory. I have attached an updated HList.cabal file that seems to work on my machine.

Re: [Haskell-cafe] Label macro expansion bug In HList.
I believe this is the case of OOHaskell gotten a bit out of sync with HList and GHC. Please use the latest code bases http://code.haskell.org/HList http://code.haskell.org/OOHaskell OCamlTutorial and all other OOHaskell code should work (with GHC 7.0.4). ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
[Haskell-cafe] Label macro expansion bug In HList.
Hi all, I am exploring OOHaskell and ran into some compilation issues with some of the samples. I hope this is the right place to report it. For example "OCamlTutorial.hs" generates the following error: ../samples/OCamlTutorial.hs:98:3: Multiple declarations of `foo' Declared at: ../samples/OCamlTutorial.hs:54:1 ../samples/OCamlTutorial.hs:98:3 Failed, modules loaded: OOHaskell, Dynamic, Print, DeepNarrow, Nominal, New. This is happening because the "label" macro on line 98: $(label "varX") doesn't expand correctly and clashes with the "foo" function on line 54: foo f = f # field1 The "label" function is found in the Data.HList.MakeLabels module and should work this way according to the docs: > runQ (label "test") >>= putStrLn . pprint data Test deriving (Data.Typeable.Internal.Typeable) test = Data.HList.FakePrelude.proxy :: Data.HList.FakePrelude.Proxy Test But I get: data Foo_0 deriving (Data.Typeable.Internal.Typeable) foo_1 = Data.HList.FakePrelude.proxy :: Data.HList.FakePrelude.Proxy Foo_0 This still doesn't cleanly explain why "OCamlTutorial.hs" is failing since it seems to be generating unique datatypes and functions by suffixing them with a number, but it seems to point to the problem. I'm hoping someone who knows HList better might understand it better. Thanks, -deech ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
