Various Paths

ghcLibDir :: FilePath Source #

Obtaining the directory for ghc system libraries.

ghcModExecutable :: IO FilePath Source #

Returns the path to the currently running ghc-mod executable. With ghc<7.6 this is a guess but >=7.6 uses getExecutablePath.

Logging

Logged messages are returned as String. Right is success and Left is failure.

Set DynFlags equivalent to "-Wall".

Monad utilities

runGhcModT' :: IOish m => GhcModEnv -> GhcModState -> GhcModT m a -> GmOutT m (Either GhcModError (a, GhcModState), GhcModLog) Source #

Run a computation inside GhcModT providing the RWST environment and initial state. This is a low level function, use it only if you know what to do with GhcModEnv and GhcModState.

You should probably look at runGhcModT instead.

hoistGhcModT :: IOish m => (Either GhcModError a, GhcModLog) -> GhcModT m a Source #

hoistGhcModT result. Embed a GhcModT computation's result into a GhcModT computation. Note that if the computation that returned result modified the state part of GhcModT this cannot be restored.

runGmlT :: IOish m => [Either FilePath ModuleName] -> GmlT m a -> GhcModT m a Source #

Run a GmlT action (i.e. a function in the GhcMonad) in the context of certain files or modules

runGmlT' :: IOish m => [Either FilePath ModuleName] -> (forall gm. GhcMonad gm => DynFlags -> gm DynFlags) -> GmlT m a -> GhcModT m a Source #

Run a GmlT action (i.e. a function in the GhcMonad) in the context of certain files or modules, with updated GHC flags

gmlGetSession :: (MonadIO m, MonadBaseControl IO m) => GmlT m HscEnv Source #

Get the underlying GHC session

gmlSetSession :: (MonadIO m, MonadBaseControl IO m) => HscEnv -> GmlT m () Source #

Set the underlying GHC session

loadTargets :: IOish m => [GHCOption] -> [FilePath] -> GmlT m () Source #

Set the files as targets and load them.
