libghc-iospec-dev - 0.3.1.1-3+b1 main

It consists of several modules, that give a pure specification
of functions in the IO monad:
.
Test.IOSpec.Fork: a pure specification of forkIO.
.
Test.IOSpec.IORef: a pure specification of most functions that create and
manipulate on IORefs.
.
Test.IOSpec.MVar: a pure specification of most functions that create and
manipulate and MVars.
.
Test.IOSpec.STM: a pure specification of atomically and the STM monad.
.
Test.IOSpec.Teletype: a pure specification of getChar, putChar, and
several related Prelude functions.
.
Besides these modules containing the specifications, there are a few other
important modules:
.
Test.IOSpec.Types: defines the IOSpec type and several amenities.
.
Test.IOSpec.VirtualMachine: defines a virtual machine on which to execute
pure specifications.
.
Test.IOSpec.Surrogate: a drop-in replacement for the other modules. Import
this and recompile your code once you've finished testing and debugging.
.
There are several well-documented examples included with the source
distribution.
.
This package provides a library for the Haskell programming language.
