name	add-wizard-handler
description	Configures @WizardHandler annotation for wizard flows. Use when creating a new wizard, setting wizard triggers, scope, or state managers for the telegram-bot library.

Add Wizard Handler

Structure

Annotate an object or class with @WizardHandler. Nest WizardStep objects inside. KSP generates WizardActivity; no manual Activity class.

@WizardHandler(trigger = ["/start"])
object MyWizard {
    object NameStep : WizardStep(isInitial = true) { ... }
    object AgeStep : WizardStep { ... }
}

Parameters

Parameter	Purpose	Default
trigger	Commands that start the wizard	Required
scope	Update types to check for trigger	[UpdateType.MESSAGE]
stateManagers	State manager classes for step storage	MapStringStateManager, MapIntStateManager, MapLongStateManager

Trigger

• trigger = ["/start"] — single command
• trigger = ["/start", "/register"] — multiple commands

Scope

• scope = [UpdateType.MESSAGE] — commands in messages (default)
• scope = [UpdateType.CALLBACK_QUERY] — button-triggered wizard

State Managers

KSP matches each step's store() return type to a state manager:

• String? → MapStringStateManager
• Int? → MapIntStateManager
• Long? → MapLongStateManager

Override per step with @WizardHandler.StateManager:

@WizardHandler(trigger = ["/start"], stateManagers = [CustomStateManager::class])
object MyWizard {
    object NameStep : WizardStep { ... }

    @WizardHandler.StateManager(OtherStateManager::class)
    object AgeStep : WizardStep { ... }
}
