RFC: hyperlinks in Haddock docs
by Simon Marlow 22 Feb '05

22 Feb '05

I'm making some changes to the way Haddock creates links, and I'd like to solicit comments on possible alternatives. The existing approach is for each non-locally-defined identifier in the current module, we hyperlink to a module that it was imported from, and that (a) actually documents the identifer, and (b) isn't hidden. There are some problems with the existing approach. It doesn't cope well with instances: instances might refer to types/classes not below the current module in the hierarchy. Also you might import an entity from a "hidden" module, but actually want to hyperlink to another module in the hierarchy, not below the current one. Hyperlinking in the documentation doesn't follow the module import hierarchy, and nor should it. So the new approach is to try to build up a global table of the "best" destinations to link to for each entity. The question is how to determine "best". Here's my first stab: - A is better than B if A directly or indirectly imports B But this isn't quite good enough: for example the Prelude re-exports a lot of stuff, but when linking Maybe for example, we probably want to link to Data.Maybe.Maybe rather than Prelude.Maybe. But the Prelude is the right place to get Int and String from. I don't particularly want the programmer to have to say for each entity where the best place to get it from is, much better would be to have a per-module flag that says "this module is a good/bad link destination". Perhaps we actually want to give an integer priority in each module. Thoughts? Better ideas? Cheers, Simon

No doubt we'd have to add a million quotes to the build system to fix this; it's not going to happen any time soon. "don't do that" Cheers, Simon

I need it at least because FreeBSD 4.x still uses gcc 2.95, > and AFAIK quite a few folks are still using that platform. I've put in a workaround for this problem, which will show up in tonight's STABLE snapshot. It works for me on FreeBSD 4.11 with gcc 2.95.4. Cheers, Simon

Configuring in directories with spaces fails in ghc6.4
by Anders Höckersten 22 Feb '05

22 Feb '05

Hi, It seems the ghc 6.4 release candidates' configure scripts fail if you run them in a directory structure containing a space. In my case, being in /home/chucky/My Downloads fails with: configure: creating ./config.status config.status: creating ghc.spec config.status: creating VERSION config.status: creating docs/users_guide/ug-book.xml config.status: creating mk/config.mk config.status: creating mk/version.mk ./configure: line 20341: cd: /home/chucky/My: No such file or directory This is on amd64 linux. Cheers, Anders

RE: gcc rc 6.4 compilation error report on Mac OS X
by Simon Marlow 21 Feb '05

Actually, this looks like the same error that Judah Jacobson encountered. Try removing ghc/includes/ghcplatform.h, re-make in ghc/includes, and continue with the build.

Hi, with the following definitions {-# OPTIONS -fglasgow-exts #-} data a :++: b class a :--: b ghci prints the infix type(classe)s as prefix: *Main> :i :++: data :++: a b -- Defined at foo.hs:2:7 *Main> :i :--: class :--: a b where -- Defined at foo.hs:3:8 or (a "real-world" example): *Main> :t fac (One:@Zero:@Zero) fac (One:@Zero:@Zero) :: :@ (:@ (:@ (:@ One One) Zero) Zero) Zero Is this a bug, a feature or just Not Implemented Yet(TM)? Groeten, Remi P.S. Are infix class-names a documented extension at all? -- Nobody can be exactly like me. Even I have trouble doing it.
