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

getLastModified :: FilePath -> IO (Maybe UTCTime) 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

Constructors FetchCallbacks logCB :: Message -> IO () statusCB :: URI -> Message -> IO () uriStartCB :: URI -> Maybe Integer -> Maybe UTCTime -> Maybe Integer -> IO () uriDoneCB :: URI -> Maybe Integer -> Maybe UTCTime -> Maybe Integer -> Maybe FilePath -> Hashes -> Bool -> IO () uriFailureCB :: URI -> Message -> IO () generalFailureCB :: Message -> IO () authorizationRequiredCB :: Site -> IO (Maybe (User, Password)) mediaFailureCB :: Media -> Drive -> IO () debugCB :: String -> IO ()

emptyFetchCallbacks :: FetchCallbacks Source

cliFetchCallbacks :: FetchCallbacks Source

data Command Source

Constructors URIAcquire URI FilePath (Maybe UTCTime) Configuration [ConfigItem] AuthorizationCredentials Site User Password MediaChanged Media (Maybe Bool)

data Status Source
