Readme for pugs-DrIFT-2.2.3.0
------------------------------------------------------------------------------
DrIFT
This package contains a source distribution of DrIFT, a tool for automatic
derivation of Haskell class instances. DrIFT was formerly known as Derive.
The current homepage is at:
<http://repetae.net/john/computer/haskell/DrIFT/>
------------------------------------------------------------------------------
Contents of this package:
- src Directory with the source files of the DrIFT tool
- example Directory with examples of using the DrIFT tool
- docs Documentation
------------------------------------------------------------------------------
If you have pulled the source from the darcs repository, you must first build
the autotools scripts by running
$ autoreconf -i
To configure and install DrIFT from source or from Hackage, you have two options.
AUTOTOOLS
You can install through the GNU Autools, like thus:
$ ./configure --prefix=<dir>
$ make install
Where <dir> is the directory in which you want to install the tool. Note that
a Haskell compiler (NHC or GHC) must be in your path. Otherwise, supply the
location of a Haskell compiler as follows:
$ ./configure --prefix=<dir> --with-hc=<Haskell compiler>
$ make install
CABAL
You can also install through Cabal, the standard Haskell packaging tool with the usual set of commands:
$ runhaskell Setup configure # optional --user --prefix=/home/user/bin
$ runhaskell Setup build
$ runhaskell Setup install # --user
(Remember, from Darcs requires autoreconf to have been run! If you are installing from Hackage, autoreconf should have already been run in the source tarball.)
------------------------------------------------------------------------------
You may optionally set the environmental variable $DERIVEPATH to the list of directories you wish to search for modules.
An example:
DERIVEPATH=/users/grad/nww/share/hugs/lib:/users/grad/nww/share/hugs/lib/hugs
to run DrIFT, simply pass the Haskell file name as an argument. You may run
'DrIFT --help' to get a summary of the various command line options
