PersistenceService

The Persistence service melds new IRCUsers (from post-processing new IRCEvents) with old records of themselves.

Sometimes the only bit of information about a sender (or target) embedded in an IRCEvent may be his/her nickname, even though the event before detailed everything, even including their account name. With this service we aim to complete such IRCUser entries as the union of everything we know from previous events.

It only needs part of UserAwareness for minimal bookkeeping, not the full package, so we only copy/paste the relevant bits to stay slim.

isEnabled bool isEnabled(): Introspects the current plugin, looking for a Settings-annotated struct member that has a bool annotated with Enabler, which denotes it as the bool that toggles a plugin on and off.
onEvent void onEvent(IRCEvent event): Forwards the supplied IRCEvent to IRCPluginImpl.onEventImpl.
this this(IRCPluginState state): Basic constructor for a plugin.
postprocess void postprocess(IRCEvent event): Lets a plugin modify an IRCEvent while it's begin constructed, before it's finalised and passed on to be handled.
initResources void initResources(): Writes plugin resources to disk, creating them if they don't exist.
deserialiseConfigFrom void deserialiseConfigFrom(string configFile, string[][string] missingEntries, string[][string] invalidEntries): Loads configuration for this plugin from disk.
setSettingByName bool setSettingByName(string setting, string value): Change a plugin's Settings-annotated settings struct member by their string name.
printSettings void printSettings(): Prints the plugin's Settings-annotated settings struct.
serialiseConfigInto bool serialiseConfigInto(Appender!(char[]) sink): Gathers the configuration text the plugin wants to contribute to the configuration file.
name string name(): Returns the name of the plugin. (Technically it's the name of the module.)
channelSpecificCommands IRCPlugin.CommandMetadata[string] channelSpecificCommands(string channelName): Compile a list of our a plugin's oneliner commands.
commands IRCPlugin.CommandMetadata[string] commands(): Forwards to IRCPluginImpl.commandsImpl.
