Haskell type classes and instances for converting between types Maintained by:haskell@FreeBSD.org Port Added: 12 Jan 2010 22:07:24 Also Listed In:haskell License: BSD
The "convertible" Haskell package provides a typeclass with a single
function that is designed to help convert between different types:
numeric values, dates and times, and the like.
The conversions perform bounds checking and return a pure Either value.
This means that you need not remember which specific function performs
the conversion you desire.
Also included in the package are optional instances that provide
conversion for various numeric and time types, as well as utilities for
writing your own instances.
Finally, there is a function that will raise an exception on
bounds-checking violation, or return a bare value otherwise, implemented
in terms of the safer function described above.

Reason:
GHC has been updated to version 7.0.4, and Haskell Platform to version
2011.4.0.0, and other Haskell ports are also updated to their Haskell
Platform versions or latest versions.
To update all affected ports:
# portmaster -r lang/ghc
or
# portupgrade -r lang/ghc

Reason:
GHC has been updated to version 7.0.3 and other Haskell ports are also

Bump PORTREVISION of all ports dependent on lang/ghc as during
upgrade, lang/ghc cabal package cache gets invalidated causing all
dependent ports to be reinstalled.

- Please welcome GHC 7.0.3
GHC in the ports tree has been updated to 7.0.3 and all other Haskell ports
are also updated to their corresponding Haskell Platform versions, or latest
versions.
We would like to acknowledge the support of the FreeBSD Donations Team and
Eotvos Lorand University, Faculty of Informatics who contributed to the server
that we used for testing.
We would also like to thank all the testers who tested FreeBSD Haskell ports
and provided their feedback.
PR: ports/156642
Approved by: tabthorpe (mentor)
Obtained from: FreeBSD Haskell
Introduce a new (and hopefully better) ports infrastructure for Haskell Cabal
ports which makes possible the direct translation of Cabal package
descriptions to FreeBSD ports. It promises both easier addition and
maintenance for Cabal-based ports.
