withMethodPath :: FilePath -> (MethodHandle -> IO a) -> IO aSource
withMethod - run |methodPath| bracketed with openMethod/closeMethod. |f| gets the open handle.
withMethodURI :: URI -> (MethodHandle -> IO a) -> IO aSource
whichMethodPath :: URI -> IO (Maybe FilePath)Source
whichMethodBinary - find the method executable associated with a URI throws an exception on failure
openMethod :: FilePath -> IO MethodHandleSource
closeMethod :: MethodHandle -> IO ExitCodeSource
recvStatus :: MethodHandle -> IO StatusSource
sendCommand :: MethodHandle -> Command -> IO ()Source
getLastModified :: FilePath -> IO (Maybe UTCTime)Source
simpleFetch :: [ConfigItem] -> URI -> FilePath -> Maybe UTCTime -> IO BoolSource
fetch :: FetchCallbacks -> [ConfigItem] -> URI -> FilePath -> Maybe UTCTime -> IO BoolSource
fetch a single item, show console output see also: getLastModified
