Readme for prelude-safeenum-0.1.1.1
prelude-safeenum
================
This is a very simple package and should be easy to install. You
should be able to use any of the following standard methods to
install it.
-- With cabal-install and without the source:
$> cabal install prelude-safeenum
-- With cabal-install and with the source already:
$> cd prelude-safeenum
$> cabal install
-- Without cabal-install, but with the source already:
$> cd prelude-safeenum
$> runhaskell Setup.hs configure --user
$> runhaskell Setup.hs build
$> runhaskell Setup.hs test
$> runhaskell Setup.hs haddock --hyperlink-source
$> runhaskell Setup.hs copy
$> runhaskell Setup.hs register
The test step is optional and currently does nothing. The Haddock
step is also optional.
Portability
===========
An attempt has been made to keep this library portable; however,
it does rely on a few language extensions. All the required language
extensions are:
CPP
GeneralizedNewtypeDeriving
MagicHash -- only for GHC
Trustworthy -- only for GHC >= 7.1
The GeneralizedNewtypeDeriving extension is used for brevity in
Data.Number.CalkinWilf. If you'd like to use this package with a
compiler that does not support that extension, contact the maintainer
and it can be removed.
This package is only "Trustworthy" rather than "Safe" for two
reasons: (1) Data.Number.CalkinWilf uses GeneralizedNewtypeDeriving,
and (2) Prelude.SafeEnum imports GHC.Exts for build/foldr fusion
and for the Char instances.
