The hermit package

[ Tags: bsd3, formal-methods, language, library, optimization, program, refactoring, reflection, transformation ] [ Propose Tags ]

HERMIT uses Haskell to express semi-formal models, efficient implementations, and provide a bridging DSL to describe via stepwise refinement the connection between these models and implementations. The key transformation in the bridging DSL is the worker/wrapper transformation.

This is a pre-alpha `please give feedback' release. Shortcomings/gotchas include:

Examples can be found in the examples sub-directory.

$ cd examples/reverse

Example of running a script.
