Documentation
checkSat :: SMTExpr Bool -> IO Bool Source #
checkSat expr launches Z3, to checks satisfiability of expr, terminating Z3
afterwards. Just a utility wrapper for checkSat'
checkSat' :: (Handle, Handle) -> SMTExpr Bool -> IO Bool Source #
checkSat' handles expr checks satisfiability of expr in an instantiated SMT solver.
This is wrapped in a push / pop, so it does not change the SMT environment
getModel :: Handle -> IO () Source #
getModel instructs an instantiated SMT solver to produce its model.
killZ3 :: SolverHandle -> IO () Source #
Kills the Z3 instance by closing the standard input stream
spawnZ3 :: IO SolverHandle Source #
Instantiates a Z3 instance, returning the solver handle for interaction
smtAdd :: [SMTExpr Int] -> SMTExpr Int Source #
Returns an SMT expression that adds all elements in the list. If the list is empty,
returns Const 0.
smtAnd :: SMTExpr Bool -> SMTExpr Bool -> SMTExpr Bool Source #
`smtAnd t u` returns an smt expression representing \( t \land u \).
smtGTE :: SMTExpr Int -> SMTExpr Int -> SMTExpr Bool Source #
`smtGTE t u` returns an SMT expression \( t \geqslant u \). If t == u, returns smtTrue.
withZ3 :: MonadIO m => (SolverHandle -> m b) -> m b Source #
withZ3 f instantiates a Z3 instance, runs f with that instance,
and then closes the instance and returns the result
type SolverHandle = (Handle, Handle) Source #
The handle (stdIn, stdOut) used for interacting with Z3
SMTLib expressions
