Running scripts

run :: Segment r -> IO r

Run a segment.

Conduit types

text :: (r ~ (), m ~ IO) => ConduitM Text Text m r -> Segment r

Work on the stream as Text values from UTF-8.

bytes :: (a ~ ByteString, m ~ IO) => ConduitM a ByteString m r -> Segment r

Lift a conduit into a segment.

General conduits

conduit :: (a ~ ByteString, m ~ IO) => ConduitM a ByteString m r -> Segment r

Lift a conduit into a segment.

conduitEither :: (a ~ ByteString, m ~ IO) => ConduitM a (Either ByteString ByteString) m r -> Segment r

Lift a conduit into a segment, which can yield stderr.

Running processes

shell :: String -> Segment ()

Run a shell command.

proc :: String -> [String] -> Segment ()

Run a process command.

($|) :: Segment () -> Segment b -> Segment b infixl 0

Fuse two segments (either processes or conduits).
