Description
SMTWriter interface for Yices, using the Yices-specific input language. This language shares many features with SMTLib2, but is not quite compatible.

Low-level interface
data Connection Source #
This is a tag used to indicate that a WriterConn is a connection
to a specific Yices process.
Instances
Arguments
| :: OutputStream Text | |
| -> InputStream Text | |
| -> (IORef (Maybe Int) -> AcknowledgementAction t Connection) | |
| -> ProblemFeatures | Indicates the problem features to support. |
| -> Integer | |
| -> SymbolVarBimap t | |
| -> IO (WriterConn t Connection) |
assume :: SMTWriter h => WriterConn t h -> BoolExpr t -> IO () Source #
Write assume formula predicates for asserting predicate holds.
sendCheck :: WriterConn t Connection -> IO () Source #
Send a check command to Yices.
sendCheckExistsForall :: WriterConn t Connection -> IO () Source #
eval :: WriterConn t Connection -> Term Connection -> IO () Source #
push :: SMTReadWriter solver => SolverProcess scope solver -> IO () Source #
Push a new solver assumption frame.
pop :: SMTReadWriter solver => SolverProcess scope solver -> IO () Source #
Pop a previous solver assumption frame.
inNewFrame :: (MonadIO m, MonadMask m, SMTReadWriter solver) => SolverProcess scope solver -> m a -> m a Source #
Perform an action in the scope of a solver assumption frame.
setParam :: WriterConn t Connection -> ConfigValue -> IO () Source #
setYicesParams :: WriterConn t Connection -> Config -> IO () Source #
data HandleReader Source #
Wrapper to help with reading from another process's standard out and stderr.
We want to be able to read from another process's stderr and stdout without
causing the process to stall because stdout or stderr becomes full. This
data type will read from either of the handles, and buffer as much data
as needed in the queue. It then provides a line-based method for reading
that data as strict bytestrings.
startHandleReader :: Handle -> Maybe (OutputStream Text) -> IO HandleReader Source #
Create a new handle reader for reading the given handle.
assertForall :: WriterConn t Connection -> [(Text, YicesType)] -> Expr -> IO () Source #
data YicesException Source #
Exceptions that can occur when reading responses from Yices
