Parsing functions
Arguments
| :: MonadFail m | |
| => [String] | |
| -> m (String, Group) | The result, a tuple of group UUID and group object |
Load a group from a field list.
Arguments
| :: MonadFail m | |
| => NameAssoc | Association list with current groups |
| -> [String] | Input data as a list of fields |
| -> m (String, Node) | The result, a tuple o node name and node object |
Load a node from a field list.
Arguments
| :: NameAssoc | Association list with the current nodes |
| -> [String] | Input data as a list of fields |
| -> Result (String, Instance) | A tuple of instance name and the instance object |
Load an instance from a field list.
loadMinMaxISpecs :: String -> String -> String -> Result MinMaxISpecs Source #
Load a single min/max ISpec pair
breakISpecsPairs :: String -> [String] -> Result [(String, String)] Source #
Break a list of ispecs strings into a list of (min/max) ispecs pairs
loadMultipleMinMaxISpecs :: String -> [String] -> Result [MinMaxISpecs] Source #
Load a list of min/max ispecs pairs
loadIPolicy :: [String] -> Result (String, IPolicy) Source #
Loads an ipolicy from a field list.
loadAllIPolicies :: List -> [String] -> Result (IPolicy, List) Source #
Loads all policies from the policy section
Arguments
| :: (MonadFail m, Element a) | |
| => [String] | Input data, as a list of lines |
| -> ([String] -> m (String, a)) | Conversion function |
| -> m (NameAssoc, Container a) | A tuple of an association list (name to object) and a set as used in Ganeti.HTools.Container |
Convert newline and delimiter-separated text.
This function converts a text in tabular format as generated by
gnt-instance list and gnt-node list to a list of objects using
a supplied conversion function.
Arguments
| :: String | Path to the text file |
| -> IO String | Contents of the file |
Load the cluser data from disk.
This is an alias to readFile just for consistency with the other
modules.
Arguments
| :: String | Text data |
| -> Result ClusterData |
Builds the cluster data from text input.
Arguments
| :: String | Path to the text file |
| -> IO (Result ClusterData) |
Top level function for data loading.
