Script

The orca.script module exposes ScriptPluginCapabilityBase for plugins that run from the Plugins dialog.

Base class	get_type() returns	Required methods	Invoked by
orca.script.ScriptPluginCapabilityBase	Script	get_name(), execute(self) -> ExecutionResult	the Plugins dialog -> Run action

Lifecycle hooks on_load() / on_unload() are optional and available on every capability (defaults do nothing).

Important

ScriptPluginCapabilityBase.execute() runs on the main/UI thread: live host handles are safe to read for the whole call and orca.host.ui dialogs open inline, but a slow execute() freezes the UI. Keep it quick; offload heavy work to your own threading.Thread (which must not touch the model) and surface results through a create_window panel.

Minimal Shape

import orca

class HelloScript(orca.script.ScriptPluginCapabilityBase):
    def get_name(self):
        return "Hello Script"

    def execute(self):
        return orca.ExecutionResult.success("Hello from a script plugin")
