Wrap +Text.Regex.Posix -regex-posix
WrapAround helps you perform calculations involving points on a finite, unbounded plane, in which objects that move across one edge of the map appear on the other. Add points, calculate distance, and so forth without worrying about the edge cases and frustrating math mistakes.
Buildwrapper is an alternative to scion. It provides services to configure, build and give information on source files to help IDEs manage Haskell projects. You can use buildwrapper to build project and retrieve errors, get outline for each module source, get the type of something inside a source file, get lexer tokens, etc. Buildwrapper is used in the EclipseFP project (Eclipse plugins for Haskell development)

This package allows you to invoke a function on one monadic type passing it an argument of a different monadic type. The canonical example is using a function such as finally or bracket to ensure cleanup is run regardless of any exceptions thrown by a computation such as x :: ReaderT MyConfig IO b. If x uses the ReaderT function ask, it cannot be re-written to run in the IO monad, and hence cannot be executed with a construction like lift (x ``finally`` cleanup). Instead, you must use the wrap method, provided by module Control.Monad.Wrap in this package.
This package contains several other modules: Control.Monad.WrapIO wraps an IO action through multiple monad transformers. Control.Monad.WrapBase generalizes the concept to other base monads besides IO. Control.Monad.MultiWrap implements mwrap, a method that behaves like wrap but allows wrapping through multiple nested layers of monad transformer. The module Control.Monad.MultiLift provides mlift, a version of lift that similarly lifts through multiple nested monad transformers.
Since this library was first released, an alternate approach was introduced by the monad-control package. monad-control is now the standard. However, this package, monad-wrap, stands as an example of accomplishing similar goals with fewer language extensions and less complexity. In particular, monad-wrap does not use RankNTypes or TypeFamilies, both required by monad-control. Moreover, monad-wrap is much smaller--no MonadWrap method requires more than one line of code. Both monad-wrap and monad-control require UndecidableInstances, but Control.Monad.Wrap itself does not require that extension, only the other modules.
Provides MonadIOUnwrappable instances for monad transformer stacks that can be run in the IO monad, with the result converted back to the monadic type. This package also includes some utilities built using MonadIOUnwrappable, such as a bracket implementation that works with MonadIO even on stacks containing one or more ErrorT transformers
Light opencl wrappers, a fork of the OpenCLRaw package.
Provides simple haskell functions to call external source code management systems. Currently git and SVN are supported.
Builds on the Win32-services package, providing a simple wrapper for turning a long-running process into a Windows service.
