Data.SBV.Trans.Control

Description

More generalized alternative to Data.SBV.Control for advanced client use

Synopsis

User queries

class MonadIO m => ExtractIO m where Source #

Monads which support IO operations and can extract all IO behavior for interoperation with functions like catches, which takes an IO action in negative position. This function can not be implemented for transformers like ReaderT r or StateT s, whose resultant IO actions are a function of some environment or state.

Methods

extractIO :: m a -> IO (m a) Source #

Law: the m a yielded by IO is pure with respect to IO.

Checking satisfiability

Result of a checkSat or checkSatAssuming call.

Constructors

Unsat

Unsatisfiable: No model is available. Unsat cores might be obtained via getUnsatCore.

Unk

Unknown: Use getUnknownReason to obtain an explanation why this might be the case.

Constructing assignments

(|->) :: SymVal a => SBV a -> a -> Assignment infix 1 Source #

Make an assignment. The type Assignment is abstract, the result is typically passed to mkSMTResult:

 mkSMTResult [ a |-> 332
             , b |-> 2.3
             , c |-> True
             ]

End users should use getModel for automatically constructing models from the current solver state. However, an explicit Assignment might be handy in complex scenarios where a model needs to be created manually.

Terminating the query

mkSMTResult :: (MonadIO m, MonadQuery m) => [Assignment] -> m SMTResult Source #

Generalization of mkSMTResult NB. This function does not allow users to create interpretations for UI-Funs. But that's probably not a good idea anyhow. Also, if you use the validateModel or optimizeValidateConstraints features, SBV will fail on models returned via this function.

exit :: (MonadIO m, MonadQuery m) => m () Source #

Generalization of exit

Controlling the solver behavior

ignoreExitCode :: SMTConfig -> Bool Source #

If true, we shall ignore the exit code upon exit. Otherwise we require ExitSuccess.

Generalization of timeout

Miscellaneous

queryDebug :: (MonadIO m, MonadQuery m) => [String] -> m () Source #

Generalization of queryDebug

echo :: (MonadIO m, MonadQuery m) => String -> m () Source #

Generalization of echo

io :: MonadIO m => IO a -> m a Source #

Generalization of io

Solver options

data SMTOption Source #

Option values that can be set in the solver, following the SMTLib specification http://smtlib.cs.uiowa.edu/language.shtml.

Note that not all solvers may support all of these!

Furthermore, SBV doesn't support the following options allowed by SMTLib.

  • :interactive-mode (Deprecated in SMTLib, use ProduceAssertions instead.)
  • :print-success (SBV critically needs this to be True in query mode.)
  • :produce-models (SBV always sets this option so it can extract models.)
  • :regular-output-channel (SBV always requires regular output to come on stdout for query purposes.)
  • :global-declarations (SBV always uses global declarations since definitions are accumulative.)

Note that SetLogic and SetInfo are, strictly speaking, not SMTLib options. However, we treat it as such here uniformly, as it fits better with how options work.
