Mutable arrays in Haskell 98
by José Romildo Malaquias 27 Mar '02

27 Mar '02

Hello. I would like to use muttable arrays in Haskell 98, with the GHC _and_ NHC98 compilers. By muttable arrays I mean arrays with in-place updates, as with the MArray arrays (which are not Haskell 98 conformant) found in GHC. Is such array implmentation available? Regards.

nhc98 1.12 FreeBSD Port and Packages
by Oliver Braun 20 Mar '02

20 Mar '02

Hi, I have built three FreeBSD nhc98 1.12 packages: Just the basic target: <URL:http://ist.unibw-muenchen.de/People/obraun/nhc98-1.12-basic-freebsd.tgz> Including the tracer: <URL:http://ist.unibw-muenchen.de/People/obraun/nhc98-1.12-with_tracer-freebsd.tgz> Including the tracer and the hat package for ghc: <URL:http://ist.unibw-muenchen.de/People/obraun/nhc98-1.12-with_tracer_ghc-freebsd.tgz> [The package including hat for ghc requires ghc 5.02.2 with packages going into ${PREFIX}/lib/ghc-5.02.2/imports/. The current ghc port in the FreeBSD ports tree fulfils this requirement.] Furthermore I have updated the port skeleton: <URL:http://ist.unibw-muenchen.de/People/obraun/nhc98.tgz> The update of the port has been already submitted to the FreeBSD project and is waiting for a committer to do his job.

Hat + GHC + -package util
by Jyrinx 18 Mar '02

18 Mar '02

My program uses the GetOpt module from the util package in ghc (thus I can't do this with nhc98). It builds just dandy (with ghc) with "hmake Dicedist -package util", but if I try to compile for Hat: --- snip --- [jyrinx@kryptonitespoon dicedist]$ hmake -T -hat -package util -package hat Dicedist # or any of several variations I've tried Fail: Can't find module GetOpt in . Or in standard libraries at /usr/lib/ghc-5.02.2/imports/std /usr/lib/ghc-5.02.2/imports/lang /usr/lib/ghc-5.02.2/imports/concurrent /usr/lib/ghc-5.02.2/imports/data /usr/lib/ghc-5.02.2/imports/net /usr/lib/ghc-5.02.2/imports/posix /usr/lib/ghc-5.02.2/imports/text /usr/lib/ghc-5.02.2/imports/util /usr/lib/ghc-5.02.2/imports/hssource /usr/lib/ghc-5.02.2/imports/greencard /usr/lib/ghc-5.02.2/imports/xlib /usr/lib/ghc-5.02.2/imports/HGL /usr/lib/ghc-5.02.2/imports/hat Asked for by: Dicedist.hs [Check settings of -I or -P flags?] Stop - hmake dependency error. --- snip --- This is a fresh build of nhc98; I haven't reconfigured anything except that the default compiler is ghc. What should I try next? Thanks for any suggestions! Jyrinx jyrinx_list(a)mindspring.com

ANNOUNCE: Hat 1.12
by Malcolm Wallace 15 Mar '02

15 Mar '02

------------------------------------ hat-1.12, nhc98-1.12, and hmake-3.02 ------------------------------------ We are pleased to announce a new release of Hat, the Haskell tracing (an debugging) system, together with supporting releases of the nhc98 compiler and the hmake compilation manager. This release of Hat is a major release. It incorporates new trace-browsing tools, and for the first time has support to compile programs for tracing with GHC in addition to nhc98. for information on hat: http://www.cs.york.ac.uk/fp/hat/ for information on nhc98: http://www.cs.york.ac.uk/fp/nhc98/ for information on hmake: http://www.cs.york.ac.uk/fp/hmake/ for downloads: http://www.cs.york.ac.uk/fp/nhc98/download.html (Hat and hmake are packaged together with nhc98 in a single download.) If you haven't already tried out the Hat tracing system, now is a good time to have a go! New features worth noting are: * There is a new tutorial introduction to Hat, showing how to generate program traces, how to explore them, and how they can help you to debug Haskell programs. * All the interactive trace browsing tools are implemented in Haskell, including a new, simpler, textual version of hat-trail. They all inter-operate, and use a similar command syntax. * The trace-generating machinery can now be used with GHC in addition to nhc98: just use `hmake -ghc -hat' instead of `hmake -nhc98 -T'. (However, for the moment, you still need to download and install the nhc98 distribution, even when you intend to trace programs only with GHC.) In addition there have also been many minor bugfixes to nhc98 and hmake. Bug reports should be sent to nhc-bugs(a)haskell.org. Discussion of the Hat system belongs on nhc-users(a)haskell.org. Regards, The Hat team at York
