Documentation

filePrefix :: String Source

File method prefix.

getUrl :: Monad m => String -> IO (m String) Source

Read an URL via curl and return the body if successful.

ioErrToResult :: IO a -> IO (Result a) Source

Helper to convert I/O errors in Bad values.

formatHost :: String -> String Source

Append the default port if not passed in.

getInstances :: NameAssoc -> String -> Result [(String, Instance)] Source

Parse a instance list in JSON format.

getNodes :: NameAssoc -> String -> Result [(String, Node)] Source

Parse a node list in JSON format.

getGroups :: String -> Result [(String, Group)] Source

Parse a group list in JSON format.

parseInstance :: NameAssoc -> JSRecord -> Result (String, Instance) Source

Construct an instance from a JSON object.

parseNode :: NameAssoc -> JSRecord -> Result (String, Node) Source

Construct a node from a JSON object.

parseGroup :: JSRecord -> Result (String, Group) Source

Construct a group from a JSON object.

parseCluster :: JSObject JSValue -> Result ([String], IPolicy) Source

Parse cluster data from the info resource.

readDataHttp Source

:: String Cluster or URL to use as source -> IO (Result String, Result String, Result String, Result String) Loads the raw cluster data from an URL.

readDataFile Source

:: String Path to the directory containing the files -> IO (Result String, Result String, Result String, Result String) Loads the raw cluster data from the filesystem.

readData Source

:: String URL to use as source -> IO (Result String, Result String, Result String, Result String) Loads data via either readDataFile or readDataHttp.

parseData :: (Result String, Result String, Result String, Result String) -> Result ClusterData Source

Builds the cluster data from the raw Rapi content.

loadData Source

:: String Cluster or URL to use as source -> IO (Result ClusterData) Top level function for data loading.
