# Documentation

type TPipelineClass (f :: Type -> Type) (m :: Type -> Type) = (Functor m, MonadIO m, Applicative m, Monad m, MonadUse f m) #

class MonadUse (f :: k -> Type) (m :: k -> Type) where #

Lift a `f` action into an `m` action.

Methods

use :: forall (a :: k). f a -> m a #

data PipeEnv #

Constructors

Fields stop_phase :: StopPhase Stop just after this phase src_filename :: String basename of original input source src_basename :: String basename of original input source src_suffix :: String its extension start_phase :: Phase output_spec :: PipelineOutput says where to put the pipeline output

data PipelineOutput #

Constructors

Temporary TempFileLifetime | Output should be to a temporary file: we're going to run more compilation steps on this output later.
Persistent | We want a persistent file, i.e. a file in the current directory derived from the input filename, but with the appropriate extension. eg. in "ghc -c Foo.hs" the output goes into ./Foo.o.
SpecificFile | The output must go into the specific outputFile in DynFlags. We don't store the filename in the constructor as it changes when doing -dynamic-too.
NoOutputFile | No output should be created, like in Interpreter or NoBackend.
