Fields

moduleSerialize :: !(Maybe (Serial st))
If the module wants its state to be saved, this function should return a Serial.
The default implementation returns Nothing.
moduleDefState :: !(LB st)
If the module maintains state, this method specifies the default state (for example in case the state can't be read from a state).
The default implementation returns an error and assumes the state is never accessed.
moduleSticky :: !Bool
Is the module sticky? Sticky modules (as well as static ones) can't be unloaded. By default, modules are not sticky.
moduleCmds :: !(ModuleT st LB [Command (ModuleT st LB)])
The commands the module listens to.
moduleInit :: !(ModuleT st LB ())
Initialize the module. The default implementation does nothing.
moduleExit :: !(ModuleT st LB ())
Finalize the module. The default implementation does nothing.
contextual :: !(String -> Cmd (ModuleT st LB) ())
Process contextual input. A plugin that implements contextual is able to respond to text not part of a normal command.
