# Documentation

data Message a where Source #

A `Message a` is a message that returns a value of type `a`. These are requests sent from GHC to the server.

Constructors

Shutdown :: Message () | Exit the iserv process
RtsRevertCAFs :: Message () |
InitLinker :: Message () |
LookupSymbol :: String -> Message (Maybe (RemotePtr ())) |
LookupClosure :: String -> Message (Maybe HValueRef) |
LoadDLL :: String -> Message (Maybe String) |
LoadArchive :: String -> Message () |
LoadObj :: String -> Message () |
UnloadObj :: String -> Message () |
AddLibrarySearchPath :: String -> Message (RemotePtr ()) |
RemoveLibrarySearchPath :: RemotePtr () -> Message Bool |
ResolveObjs :: Message Bool |
FindSystemLibrary :: String -> Message (Maybe String) |
CreateBCOs :: [ByteString] -> Message [HValueRef] | Create a set of BCO objects, and return HValueRefs to them Note: Each ByteString contains a Binary-encoded [ResolvedBCO], not a ResolvedBCO. The list is to allow us to serialise the ResolvedBCOs in parallel. See `createBCOs` in compilerghciGHCi.hsc.
FreeHValueRefs :: [HValueRef] -> Message () | Release `HValueRef`s
AddSptEntry :: Fingerprint -> HValueRef -> Message () | Add entries to the Static Pointer Table
MallocData :: ByteString -> Message (RemotePtr ()) | Malloc some data and return a `RemotePtr` to it
MallocStrings :: [ByteString] -> Message [RemotePtr ()] |
PrepFFI :: FFIConv -> [FFIType] -> FFIType -> Message (RemotePtr C_ffi_cif) | Calls `prepareForeignCall`
FreeFFI :: RemotePtr C_ffi_cif -> Message () | Free data previously created by `PrepFFI`
MkConInfoTable :: Int -> Int -> Int -> Int -> ByteString -> Message (RemotePtr StgInfoTable) | Create an info table for a constructor
EvalStmt :: EvalOpts -> EvalExpr HValueRef -> Message (EvalStatus [HValueRef]) | Evaluate a statement
ResumeStmt :: EvalOpts -> RemoteRef (ResumeContext [HValueRef]) -> Message (EvalStatus [HValueRef]) | Resume evaluation of a statement after a breakpoint
AbandonStmt :: RemoteRef (ResumeContext [HValueRef]) -> Message () | Abandon evaluation of a statement after a breakpoint
EvalString :: HValueRef -> Message (EvalResult String) | Evaluate something of type `IO String`
EvalStringToString :: HValueRef -> String -> Message (EvalResult String) | Evaluate something of type `String -> IO String`
EvalIO :: HValueRef -> Message (EvalResult ()) | Evaluate something of type `IO ()`
MkCostCentres :: String -> [(String, String)] -> Message [RemotePtr CostCentre] | Create a set of CostCentres with the same module name
CostCentreStackInfo :: RemotePtr CostCentreStack -> Message [String] | Show a `CostCentreStack` as a `[String]`
NewBreakArray :: Int -> Message (RemoteRef BreakArray) | Create a new array of breakpoint flags
EnableBreakpoint :: RemoteRef BreakArray -> Int -> Bool -> Message () | Enable a breakpoint
BreakpointStatus :: RemoteRef BreakArray -> Int -> Message Bool | Query the status of a breakpoint (True = enabled)
GetBreakpointVar :: HValueRef -> Int -> Message (Maybe HValueRef) | Get a reference to a free variable at a breakpoint
StartTH :: Message (RemoteRef (IORef QState)) | Start a new TH module, return a state token that should be
RunTH :: RemoteRef (IORef QState) -> HValueRef -> THResultType -> Maybe Loc -> Message (QResult ByteString) | Evaluate a TH computation. Returns a ByteString, because we have to force the result before returning it to ensure there are no errors lurking in it. The TH types don't have NFData instances, and even if they did, we have to serialize the value anyway, so we might as well serialize it to force it.
RunModFinalizers :: RemoteRef (IORef QState) -> [RemoteRef (Q ())] -> Message (QResult ()) | Run the given mod finalizers.
GetClosure :: HValueRef -> Message (GenClosure HValueRef) | Remote interface to GHC.Exts.Heap.getClosureData. This is used by the GHCi debugger to inspect values in the heap for :print and type reconstruction.
Seq :: HValueRef -> Message (EvalResult ()) | Evaluate something. This is used to support :force in GHCi.

data EvalExpr a Source #

We can pass simple expressions to EvalStmt, consisting of values and application. This allows us to wrap the statement to be executed in another function, which is used by GHCi to implement :set args and :set prog. It might be worthwhile to extend this little language in the future.
