This plugin displays a hello message both on the status bar of the PyJAMAS window and in the terminal.

from pyjamas.rplugins.base import PJSPluginABC

# PyJAMAS plugins inherit from the abstract class
# pyjamas.rplugins.base.PJSPluginABC,
# and must implement name and run methods.
class PJSPlugin(PJSPluginABC):
    # This method returns the name of the menu item used to
    # launch the plugin.
    def name(self) -> str:
        return "Sample plugin"

    # This method implements the functionality of the plugin.
    def run(self, parameters: dict) -> bool:
        print("Hello my friends!")
        self.pjs.statusbar.showMessage("Hello my friends!")

        return True
