withMethodPath :: FilePath -> (MethodHandle -> IO a) -> IO a

withMethod - run |methodPath| bracketed with openMethod/closeMethod. |f| gets the open handle.

withMethodURI :: URI -> (MethodHandle -> IO a) -> IO a

whichMethodPath :: URI -> IO (Maybe FilePath)

whichMethodBinary - find the method executable associated with a URI throws an exception on failure

openMethod :: FilePath -> IO MethodHandle

closeMethod :: MethodHandle -> IO ExitCode

recvStatus :: MethodHandle -> IO Status

sendCommand :: MethodHandle -> Command -> IO ()

getLastModified :: FilePath -> IO (Maybe UTCTime)

simpleFetch :: [ConfigItem] -> URI -> FilePath -> Maybe UTCTime -> IO Bool

fetch :: FetchCallbacks -> [ConfigItem] -> URI -> FilePath -> Maybe UTCTime -> IO Bool

fetch a single item, show console output see also: getLastModified

emptyFetchCallbacks :: FetchCallbacks

set of callbacks which do nothing. suitable for non-interactive usage. In the case authorization is required, no credentials will be supplied and the download should abort.
