I hear that the summer is busiest with respect to interns, but those who can arrange it with their graduate programs ought to consider applying for an internship during the school year. I don't know what things are like now, but I found that there were plenty of other interns around to keep me company even during the fall, and Cambridge is a lovely place to spend an autumn as well.

GHCi is being too "helpful"
by Dinko Tenev 25 Jan '08

25 Jan '08

Hi everyone, When evaluating an IO monad in GHCi from the 6.6.1 distribution, the REPL tries to be a bit too smart about printing out the returned value. For example, () values are not printed: Prelude System.Directory> setCurrentDirectory "work" Prelude System.Directory> ...but String, or, as far as I can see, any other values, do get printed: Prelude System.Directory> getCurrentDirectory "/home/shinobi" Prelude System.Directory> set In my particular case, the value printed is a 250,000-element list -- waiting for the value to print out is not an option. I don't want to see the whole list at once, but do need to examine parts of it, subject it to intermediate transformations, etc. Is there any way to suppress this output and revert to the old behavior, where the value was simply bound to "it", without being printed? Thanks, D. Tenev

Network.CGI changes
by Frederik Eaton 25 Jan '08

25 Jan '08

Hello all, About two years ago, I wrote a web page for one of my projects, using Network.CGI. I chose that over WASH because it had a simple interface and I thought it would be more stable as a result. Now, Bjorn Bringert has replaced the interface with a completely different one. There is a cgi-compat, but it doesn't build with GHC 6.8.2. Does anyone know a quick way to get my web page functioning again? Is there an early version of Network.CGI (with the 'wrapper' interface) that still compiles under GHC 6.8.2? I'm a bit reluctant to convert my code to the new interface, because it will probably change completely again in a year or so, and I'd rather not have to keep revisiting my project and rewriting the web page... Anyway, I am attaching the source file. Thanks in advance, Frederik P.S. Sometimes programmers make a rule of changing the names of things when they change the interface; this makes it possible to keep the old interface alongside the new one, so code which depends on the old interface don't have to change. Is there a reason why the Haskell community does not adopt this practice? It seems that people are always saying that there is a lack of manpower in this community, perhaps that is an excellent reason to make *fewer* incompatible changes, rather than more? -- http://ofb.net/~frederik/

ghc -O
by Matthew Naylor 24 Jan '08

24 Jan '08

Hello GHC gurus, specifying "-O" or "-O2" to GHC enables various optimisations to the frontend of the compiler, but I wonder does it turn on any optimistions to the backend/code-generator that are independent of the frontend? I can imagine that knowledge such as strictness which is computed by frontend would enable optimisations in the backend, but I'm more interested in whether the backend would do anything independent (e.g. peephole optimistion, C compiler options) with "-O" but not without. Thanks, Matt.

Link failures using GHC 6.8.2 on OS X 10.1.11 (PPC)
by Robin Houston 23 Jan '08

23 Jan '08

This morning I downloaded and installed ghc-6.8.2-powerpc-apple-darwin.tar.bz2. I'm now getting link errors when I use ghc. For example, the simple program import qualified Data.IntSet as IntSet main = print $ IntSet.empty gives the errors: /usr/bin/ld: Undefined symbols: ___stginit_containerszm0zi1zi0zi1_DataziIntSet_ _containerszm0zi1zi0zi1_DataziIntSet_empty_closure _containerszm0zi1zi0zi1_DataziIntSet_zdf3_closure These symbols are defined in /usr/local/lib/ghc-6.8.2/lib/containers-0.1.0.1/libHScontainers-0.1.0.1.a, so apparently the linker is not finding this library. The same program does work in ghci, and in ghc-6.6 (which I was using previously). I've searched the list archives, and I haven't found any mention of this problem. Any help would be much appreciated! Robin

Re: Integrating editline with ghc

In short, consider a split up of the readline package into readline-basics and readline-exts (both with GPL licence). Unfortunately it is not possible to have the package readline to be the union of readline-basics and readline-exts. So readline-basic (or readline-compat) would be a duplication of a reduced readline package. For porting packages from libreadline to libedit it would be sufficient to replace readline-basics with editline (and change the licence) in *.cabal files. Packages depending on more then readline-basics cannot be ported. I'm only worried if any package maintainer would bother to change the build-depends from readline to readline-basic (if not forced to change it anyway, i.e. to readline-basic and readline-ext). Alternatively, if the interface of readline is reduced to that of readline-basic, package maintainers could hope that their package is still okay and if not (after compilation errors) add readline-ext to their build-depends. Is this really such a crazy idea? Christian

Integrating editline with ghc
by Judah Jacobson 22 Jan '08

22 Jan '08

Hi all, I have managed to build ghc using the initial release of the editline package: Hackage link: http://hackage.haskell.org/cgi-bin/hackage-scripts/package/editline-0.1 Haddock: http://code.haskell.org/editline/dist/doc/html/editline/ As I've mentioned before, there are two independent modules: - System.Console.Editline is a very basic (and experimental) interface to the native editline APIs. - System.Console.Editline.Readline contains the readline APIs provided by the editline library (mostly a cut/paste of System.Console.Readline). Currently I'm using just the latter as a drop-in replacement for System.Console.Readline in ghci. I have added a --with-editline flag to ghc's configure script, which has no effect if it's not specified, and otherwise does the following: - Throw an error (at configure time) if editline isn't present (as $hardtop/libraries/editline) - Use the editline package instead of readline when building ghc stage 2 - Use CPP to make InteractiveUI.hs (the main ghci loop) import System.Console.Editline.Readline instead of System.Console.Readline. Does that sound like the right way to handle this? If so, I'll send a darcs patch. Also, should editline be made a boot-package or an extra-package (or neither)? Thanks, -Judah

GHC 6.8.2 for mac PPC and HAppS
by manu 22 Jan '08

22 Jan '08

I've installed Christian's 6.8.2 binary on my PPC Mac at home (OS X 10.4) and wen I try to install HAppS : manu-2:~/Sites/MyProject manu$ sp ghc -isrc src/Main.hs --make --run -- http-port=5000 I get : downloading modules... <><sp: Maybe.fromJust: Nothing It's strange the same command worked totally on an Intel Mac (OSX 10.5) I've asked the HAppS mailing list and someone said : > I had this issue too... > After manually compiling GHC (i was using Debian's package) and then > recompiling sp, It has gone away.... Wonder what it was. So I wonder, to what extent is it due to my ghc install ? Thanks Emmanuel
