Description

Running TH splices

Synopsis

startTH :: IO (RemoteRef (IORef QState))
runModFinalizerRefs :: Pipe -> RemoteRef (IORef QState) -> [RemoteRef (Q ())] -> IO ()
runTH :: Pipe -> RemoteRef (IORef QState) -> HValueRef -> THResultType -> Maybe Loc -> IO ByteString
data GHCiQException = GHCiQException QState String

Documentation

startTH :: IO (RemoteRef (IORef QState)) Source #

The implementation of the StartTH message: create a new IORef QState, and return a RemoteRef to it.

runModFinalizerRefs :: Pipe -> RemoteRef (IORef QState) -> [RemoteRef (Q ())] -> IO () Source #

Runs the mod finalizers.

The references must be created on the caller process.

Arguments

:: Pipe

-> RemoteRef (IORef QState)

The TH state, created by startTH

The splice to run

-> THResultType

What kind of splice it is

The source location

-> IO ByteString

Returns an (encoded) result that depends on the THResultType

The implementation of the RunTH message

data GHCiQException Source #

The exception thrown by "fail" in the GHCiQ monad

Constructors

GHCiQException QState String
