Racket bindings for Z3

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 tests and 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!

Please see the Downloads section for a downloadable copy of the paper we submitted to TFP'12.

Installing

z3.rkt requires Z3 4.0, which you can download for your platform from the Microsoft Research site. We work on Windows, Mac and Linux. You need to copy or create a symlink to z3.dll, libz3.so or libz3.dylib in this directory.
