So you don't think the .o files should be collected together into a library? -- Ashley Yakeley, Seattle WA

Unix Dir for .hi Import Files
by Ashley Yakeley 08 Jun '02

08 Jun '02

I'm not sure if there's any standardisation effort or intent for .hi files, or whether they are likely to remain GHC-specific for the forseeable future, but I was wondering if there should be a standard UNIX directory to put them in. For instance: /usr/share/haskell-import/Org/Org/Semantic/HBase/Basic/Trivial.hi ...much like C has "/usr/include/". -- Ashley Yakeley, Seattle WA

I've asked Warrick if he'd like to incorporate his HTTP client implementation into the hierarchical libraries, and maintain it. He's happy to do that. Does anyone have any objections or comments? The HTTP module itself can go in Network.Protocols.HTTP, and Browser maybe in Network.Protocols.HTTP.Browser. Base64 is a little more generic - perhaps FileFormat.Base64? Cheers, Simon

Module Hierarchy Question
by Ashley Yakeley 07 Jun '02

07 Jun '02

Is it wrong or discouraged to have both modules "A.B" and "A.B.C"? For instance, I want to create a number of modules: Org.Org.Semantic.HBase.Basic.Trivial Org.Org.Semantic.HBase.Basic.Logic Org.Org.Semantic.HBase.Basic.Equivalence Org.Org.Semantic.HBase.Basic.Type etc. ... and then have a single module that collects them all up: module Org.Org.Semantic.HBase.Basic ( module Org.Org.Semantic.HBase.Basic.Trivial, module Org.Org.Semantic.HBase.Basic.Logic, module Org.Org.Semantic.HBase.Basic.Equivalence, module Org.Org.Semantic.HBase.Basic.Type, etc. ) where { import Org.Org.Semantic.HBase.Basic.Trivial; import Org.Org.Semantic.HBase.Basic.Logic; import Org.Org.Semantic.HBase.Basic.Equivalence; import Org.Org.Semantic.HBase.Basic.Type; etc. } -- Ashley Yakeley, Seattle WA

Haskell HBLAS Library
by Hal Daume III 03 Jun '02

03 Jun '02

Hi All, I've just finished porting the BLAS linear algebra library to Haskell and am about to begin porting the LAPACK lin alg extensions. Currently the "package" looks very flat: HBlas.Types -- basic type HBlas.Convert -- basic conversion routines HBlas.Level1 -- BLAS level1 routines HBlas.Level2 -- BLAS level2 routines HBlas.Level3 -- BLAS level3 routines since I intend to share types between the HBlas system and the HLapack system, I intend to (shortly) make it something like: LinAlg.Types -- basic types LinAlg.Convert -- conversion LinAlg.HBlas.Level1 .Level2 .Level3 LinAlg.HLapack.and-so-on Before I do this, since changing module names is nontrivial, I was looking for some input whether this would be sufficient, or if I should make it Math.LinAlg... or something else. or Contrib.LinAlg or whatever. I don't mean to start a huge discussion; if there's a correct thing to do, and someone would tell me that, that's sufficient. Also, I'm looking for someone to help me out packaging it all up; I know very little about making makefiles, etc. The whole package is fairly complicated, since it requries BLAS to be installed, greencard to be run, the haskell to be compiled, and haddock to generate the documentation. Hopefully someone will volunteer. Finally, I've been trying to make myself document the library; you can find a somewhat recent version of the haddock docs at: http://www.isi.edu/~hdaume/HBlas but this will probably move shortly. - Hal -- Hal Daume III "Computer science is no more about computers | hdaume(a)isi.edu than astronomy is about telescopes." -Dijkstra | www.isi.edu/~hdaume

Suggestions on improvements are welcome. I tried HTTP.hs and Base64.hs a little and they seem to work well so far. I think your http library would make a useful addition to the Haskell libraries, at least as a starting point for a standard HTTP library. Jens

small patch for HsLexer.lhs in hdoc 0.8.2
by Martin Norbäck 16 May '02

16 May '02

Thanks for the new version of hdoc! I've found one bug in the HsLexer.lhs file (which was introduced with the new stuff from hsparser I think). I gets the source location all mixed up when character literals are present. It seems the same bug is present in the new Language:Haskell.Lexer so I send this to libraries(a)haskell.org as well. Even though the patch doesn't apply automatically there, it should be easy to apply by hand. The patch is attached.

I've just added support for existential quantifiers in datatype declarations. You should find that Haddock already supports universals - in fact it allows 'forall' in exactly the same places as GHC (i.e. virtually everywhere). Cheers, Simon

Using Haddock for standard libraries (was: RE: ANNOUNCE: Haddock version 0.1, a Haskell documentation tool)
by Krasimir Angelov 08 May '02

Hi Haddock is very cool idea. I like it, but I see that Haddock doesn't support existencial and universal quntified types. Is it too difficult to implement that? I want to rewrite Object I/O documentation but I need support for these features. I'll volunteer to extend Haddock if there isn't any who already work about that.
