Data.Machine.ByteString

Sources

fromLazy :: ByteString -> Source ByteString

Transform a lazy ByteString into a Source of strict ByteString.

fromStrict :: ByteString -> Source ByteString

Use a strict ByteString as Source

fromHandle :: MonadIO m => Handle -> SourceT m ByteString

Use an Handle to create a Source of strict ByteString.

hGet :: MonadIO m => Int -> Handle -> SourceT m ByteString

Read chunks of strict ByteString of fixed size.

hGetSome :: MonadIO m => Int -> Handle -> SourceT m ByteString

Like hGet but may be returned smaller chunks if there are not enough data immediately available.

hGetNonBlocking :: MonadIO m => Int -> Handle -> SourceT m ByteString

Similar to hGet but it will never block waiting for data.

Sinks

stdin :: MonadIO m => SourceT m ByteString

Source that stream bytes from stdin

stdout :: MonadIO m => MachineT m (Is ByteString) ()

Stream data to stdout

stderr :: MonadIO m => MachineT m (Is ByteString) ()

Stream data to stderr

toHandle :: MonadIO m => Handle -> MachineT m (Is ByteString) ()

Create a Machine that stream its input to the given Handle

interact :: Process ByteString ByteString -> IO ()

Use a Process ByteString ByteString to transform the input from stdin and output to stdout

Processes

mapping :: (Word8 -> Word8) -> Process ByteString ByteString

Transform every byte of a ByteString

filtered :: (Word8 -> Bool) -> Process ByteString ByteString

Allow to pass only the bytes that satisfy the predicate

taking :: Integral n => n -> Process ByteString ByteString

Stream only the first n bytes

takingWhile :: (Word8 -> Bool) -> Process ByteString ByteString

Stream bytes until they fail the predicate

scan :: (Word8 -> Word8 -> Word8) -> Word8 -> Process ByteString ByteString

Strict left scan over the bytes

pack :: Process Word8 ByteString

Convert a stream of Bytes into a stream of strict ByteString of size equal to defaultChunkSize

unpack :: Process ByteString Word8

Convert a stream of strict ByteString into a stream of Bytes
