# `emit` (`event,` `**extra`)

- Method of Plugin

This method can be used to emit an event that other plugins can hook. The event name is prefixed with the plugin ID.

## Example

    from lektor.pluginsystem import Plugin

    class MyPlugin(Plugin):

        def on_setup_env(self, **extra):
            self.emit('setup', foo=42)

Another plugin can then hook this:

    from lektor.pluginsystem import Plugin

    class MyPlugin(Plugin):

        def on_my_plugin_setup(self, foo, **extra):
            print('got %s' % foo)

(This assumes the plugin id is set to `my-plugin` in `setup.py`)
