this leads to a few problems:

   * The tools are not always identical in functionality.

   * The tools fight for a global generic name like "/usr/bin/runhaskell".

These problems are not new and not unique to Haskell implementations, so for
*nix-based system there is a tool called update-alternatives which handles
those cases. The idea is as follows:

   * Each program/man page/etc. installs itself with a very specific name
     like /usr/bin/hsc2hs-ghc or /usr/share/man/man1/lua5.1.1.gz, so nothing
     clashes.

   * The (un-)installation scripts call update-alternatives to notify the
     system about new alternatives for a generic tool/manpage/etc.

   * Alternatives can be grouped together ("link groups"), so e.g. switching
     from Sun's Java to Kaffe switches compiler, JRE, manpages etc. together.
     Alas, this doesn't work well with the Haskell implementations yet,
     because they come with different sets of tools (in addition to runFOO):

       GHC:  hsc2hs
       Hugs: hsc2hs, cpphs
       nhc:  cpphs

     Either these tools should be disentangled fromt the Haskell
     implementations or all implementations should offer the same set.
     Opinions and recommendations on this topic are highly welcome.

   * This mechanism can be used to easily switch between several versions of
     the same implementation, too, but we are not yet fully prepared for that.

As a first step, GHC now installs hsc2hs as 'hsc2hs-ghc' and does *not*
install runhaskell directly anymore, only runghc. hsc2hs and runhaskell are
created via update-alternatives now. What is currently missing is a mechanism
for platforms like Windows and probably Mac OS X.

12 years agoMake the type-defaulting in GHCi use () as the first default type
simonpj@microsoft.com [Thu, 15 Mar 2007 14:28:12 +0000 (14:28 +0000)] 
Make the type-defaulting in GHCi use () as the first default type

See Trac #1200

This is a somewhat experimental fix.  I'm not sure we want it in 6.6.1

The idea is explained in Note [Default unitTy] in TcSimplify.  In
interative mode (or with -fextended-default-rules) we add () as the
first type we try when defaulting.  This has very little real impact,
except in the following case.  Consider:
Text.Printf.printf "hello"
This has type (forall a. IO a); it prints "hello", and returns
'undefined'.  We don't want the GHCi repl loop to try to print that
'undefined'.  The neatest thing is to default the 'a' to (), rather
than to Integer (which is what would otherwise happen; and then GHCi
doesn't attempt to print the ().  So in interactive mode, we add () to
the list of defaulting types.

Added support for parallel builds

With this patch, one can define the degree of build parallelism via a 'jobs'
rpm variable. A comfortable way to use this is having a ~/.rpmmacros file with
a line like:

   %jobs 2

Alternatively, one could use a '--define "jobs 2"' command line flag for
rpmbuild. On a Core 2 Duo using 2 jobs brings down the time for a full build
including extralibs from 36m to 27m. If 'jobs' is not defined, a normal
sequential build is done, following the usual conventions on e.g. openSUSE.
