Test.IOSpec Version 1.0
I'm pleased to announce the first release of the Test.IOSpec library, that provides a pure specification of some functions in the IO monad. This may be of interest to anyone who wants to debug, reason about, analyse, or test impure code.
Essentially, by importing libraries from IOSpec you can the same code you would normally write in the IO monad. Once you're satisfied that your functions are reasonably well-behaved, you can remove the Test.IOSpec import and replace it with the "real" functions instead.
Website: www.cs.nott.ac.uk/~wss/repos/IOSpec Darcs: darcs get www.cs.nott.ac.uk/~wss/repos/IOSpec Tarball: www.cs.nott.ac.uk/~wss/repos/IOSpec/dist/IOSpec-0.1.tar.gz Haddock: www.cs.nott.ac.uk/~wss/repos/IOSpec/dist/doc/html
Several examples are included with the sources.
At the moment, the library consists of the following modules:
* Test.IOSpec.Teletype: a specification of getChar and putChar. * Test.IOSpec.IORef: a specification of most functions on IORefs. * Test.IOSpec.Concurrent: specification of forkIO and MVars.
As an added feature, running concurrent code using Test.IOSpec.Concurrent will detect deadlocks, instead of looping indefinitely.
Future work includes:
* Improving the interface, making it easier to combine functions from different modules. * Adding more functionality: STM and weak pointers seem likely candidates.
If you have any questions, comments, or feedback, please do get in touch.
