pyi_hooksample/ __init__.py - Hook sample package

This is a trivial package, which contains a hidden import and depends on a data file. For these reasons, this library needs PyInstaller hooks in order to be frozen properly by PyInstaller.

 
import pkgutil
import importlib

__version__ = "0.1"
__all__ = ["do_import", "print_message"]
 

do_import

Uses importlib to import the _hidden.py - A hidden import module. Since PyInstaller only performs static analysis, it cannot detect this import.

def do_import():

Direct use of __import__() is discouraged in favor of importlib.import_module().

    importlib.import_module('._hidden', __name__)
 

print_message

Relies on a data file to work correctly. PyInstaller must be instructed to include this file when freezing for the program to run correctly.

def print_message():
    msg = pkgutil.get_data(__name__, 'message.txt').decode().rstrip()
    print("Message from ", __name__, ": ", msg, sep="")
