Running scripts
Conduit types
text :: forall r (m :: Type -> Type). (r ~ (), MonadThrow m) => ConduitT Text Text m r -> Segment m r Source #
Work on the stream as Text values from UTF-8.
bytes :: forall a (m :: Type -> Type) r. (a ~ ByteString, Monad m) => ConduitT a ByteString m r -> Segment m r Source #
Lift a conduit into a segment.
General conduits
conduit :: forall a (m :: Type -> Type) r. (a ~ ByteString, Monad m) => ConduitT a ByteString m r -> Segment m r Source #
Lift a conduit into a segment.
conduitEither :: forall a (m :: Type -> Type) r. (a ~ ByteString, Monad m) => ConduitT a (Either ByteString ByteString) m r -> Segment m r Source #
Lift a conduit into a segment, which can yield stderr.
Running processes
shell :: forall (m :: Type -> Type). MonadIO m => String -> Segment m () Source #
Run a shell command.
proc :: forall (m :: Type -> Type). MonadIO m => String -> [String] -> Segment m () Source #
Run a process command.
($|) :: forall (m :: Type -> Type) b. MonadUnliftIO m => Segment m () -> Segment m b -> Segment m b infixl 0 Source #
Fuse two segments (either processes or conduits).
data Segment (m :: Type -> Type) r Source #
A pipeable segment. Either a conduit or a process.
