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

Fields

emptyFetchCallbacks :: FetchCallbacks Source
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.
