-- | Mongrel2 Handler Library
--   
--   Mongrel2 Handler Library. This handler library requires that the
--   Mongrel2 server is set up to use the <a>tnetstring</a> protocol.
@package mongrel2-handler
@version 0.3.1

module Mongrel2
data Handler
data ConnectedHandler

-- | Create a new handler. <tt>mkHandler pullFromAddress publishToAddress
--   id</tt> creates a handler which pulls requests from
--   <tt>fromAddress</tt> and publishes replies to <tt>publishAddress</tt>.
mkHandler :: String -> String -> Maybe String -> Handler

-- | Run an IO action with a connected handler.
withConnectedHandler :: Handler -> (ConnectedHandler -> IO a) -> IO a

-- | Receive a parsed request from the Mongrel2 server. Blocks until a
--   message is received. The Mongrel2 server will signal a client
--   disconnect by sending a Request with method <tt>JSON</tt> and a
--   request body containing a JSON object with a key <tt>type</tt>
--   containing the value <tt>disconnect</tt>. No response should be sent
--   for such a request.
receiveRequest :: ConnectedHandler -> IO (Connection, Request)

-- | Send a reply to the Mongrel2 server.
sendReply :: ConnectedHandler -> UUID -> [ClientID] -> Builder -> IO ()

-- | Build a HTTP response.
buildResponse :: Status -> ResponseHeaders -> ByteString -> Builder

-- | Client identifier from Mongrel2. This identifies the currently
--   connected client uniquely.
type ClientID = Int64

-- | Connection information.
data Connection
Connection :: UUID -> ClientID -> Connection

-- | UUID of the connected Mongrel2 server.
connServerUUID :: Connection -> UUID

-- | ID of the connected client browser.
connClientID :: Connection -> ClientID

-- | Request information.
data Request
Request :: [Text] -> Query -> ByteString -> Either Ascii StdMethod -> Maybe HttpVersion -> RequestHeaders -> ByteString -> Request

-- | Request path
reqPath :: Request -> [Text]

-- | Query part of the request
reqQuery :: Request -> Query

-- | Raw request path including query part.
reqRawPath :: Request -> ByteString

-- | Request method (GET, POST, etc.)
reqMethod :: Request -> Either Ascii StdMethod

-- | HTTP version
reqVersion :: Request -> Maybe HttpVersion

-- | Request headers
reqHeaders :: Request -> RequestHeaders

-- | Request body.
reqBody :: Request -> ByteString

-- | UUID for communicating with Mongrel2.
