z3.rkt: Racket bindings for Z3
We aim to provide a reasonably complete and easy-to-use implementation of Z3 on Racket. The documentation is rather incomplete right now, but here's what's working:
- Basic assertions on integers, booleans, arrays and integer lists
- Custom datatypes: only scalar datatypes supported right now
- Extracting values from generated models
- A few examples, including Sudoku, n-queens, and bounded model checking for quicksort
Check out the
examples subdirectories for examples. For a
slightly more involved example, see numbermind,
a small web app written using this library.
Important things to do:
- Better model navigation
- Assertions on other types of lists and other non-scalar datatypes
- More examples, a more comprehensive test suite
- Better debugging and printing
Pull requests are always welcome!
