Documentation

relaunchMaster :: Maybe [String] -> IO ()

Just relaunch the master binary. We don't have any important state to worry about. (Or, like when 'relaunchWith<X>State' calls it, we're managing state on our own). It takes an argument which can optionally specify a new set of arguments. If it is given a value of Nothing, the current value of getArgs will be used.

relaunchWithTextState :: Show a => a -> Maybe [String] -> IO ()

Relaunch the master binary, but first preserve the program state so that we can use the restoreTextState functions to get it back again later.

relaunchWithBinaryState :: Binary a => a -> Maybe [String] -> IO ()

Serialize the state for later restoration with restoreBinaryState, and then relaunch the master binary.

saveTextState :: Show a => a -> IO ()

Serialize a state as text, for later loading with the restoreTextState function.

saveBinaryState :: Binary a => a -> IO ()

Serialize a state as binary data, for later loading with the restoreBinaryState function.

restoreTextState :: Read a => a -> IO a

Restore state which has been serialized through the saveTextState function. Takes a default which is returned if the state doesn't exist.

restoreBinaryState :: Binary a => a -> IO a

Restore state which has been serialized through the saveBinaryState function. Takes a default which is returned if the state doesn't exist.
