What4.Solver.Yices

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

This is a tag used to indicate that a WriterConn is a connection to a specific Yices process.

eval :: WriterConn t Connection -> Term Connection -> IO ()

push :: SMTReadWriter solver => SolverProcess scope solver -> IO ()

data HandleReader

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

Create a new handle reader for reading the given handle.
