This is an alternative build system that delegates everything to the make
program. All the commands just end up calling make
with appropriate
arguments. The intention was to allow preexisting packages that used
makefiles to be wrapped into Cabal packages. In practice essentially all
such packages were converted over to the "Simple" build system instead.
Consequently this module is not used much and it certainly only sees cursory
maintenance and no testing. Perhaps at some point we should stop pretending
that it works.
Uses the parsed command-line from Distribution.Simple.Setup in order to build Haskell tools using a back-end build system based on make. Obviously we assume that there is a configure script, and that after the ConfigCmd has been run, there is a Makefile. Further assumptions:
- ConfigCmd
- We assume the configure script accepts
--with-hc
,--with-hc-pkg
,--prefix
,--bindir
,--libdir
,--libexecdir
,--datadir
. - BuildCmd
- We assume that the default Makefile target will build everything.
- InstallCmd
- We assume there is an
install
target. Note that we assume that this does *not* register the package! - CopyCmd
- We assume there is a
copy
target, and a variable$(destdir)
. Thecopy
target should probably just invokemake install
recursively (e.g.$(MAKE) install prefix=$(destdir)/$(prefix) bindir=$(destdir)/$(bindir)
. The reason we can't invokemake install
directly here is that we don't know the value of$(prefix)
. - SDistCmd
- We assume there is a
dist
target. - RegisterCmd
- We assume there is a
register
target and a variable$(user)
. - UnregisterCmd
- We assume there is an
unregister
target. - HaddockCmd
- We assume there is a
docs
ordoc
target.

data Version :: *
A Version
represents the version of a software entity.
An instance of Eq
is provided, which implements exact equality
modulo reordering of the tags in the versionTags
field.
An instance of Ord
is also provided, which gives lexicographic
ordering on the versionBranch
fields (i.e. 2.1 > 2.0, 1.2.3 > 1.2.2,
etc.). This is expected to be sufficient for many uses, but note that
you may need to use a more specific ordering for your versioning
scheme. For example, some versioning schemes may include pre-releases
which have tags "pre1"
, "pre2"
, and so on, and these would need to
be taken into account when determining ordering. In some cases, date
ordering may be more appropriate, so the application would have to
look for date
tags in the versionTags
field and compare those.
The bottom line is, don't always assume that compare
and other Ord
operations are the right thing for every Version
.
Similarly, concrete representations of versions may differ. One
possible concrete representation is provided (see showVersion
and
parseVersion
), but depending on the application a different concrete
representation may be more appropriate.
