Tutorial 03: Filename

Personally I don’t like the .py extension for CLI apps. And clik doesn’t care. So the demo app will be renamed to just todo.

Since the filename no longer has an extension, we’ll add a modeline to keep it editor-friendly. We’ll add the encoding specifier as well, since that is good practice in general:

#!bin/python
# -*- coding: utf-8; mode: python -*-

if __name__ == '__main__':
    print('Hello, world!')

Renaming and running the app should produce the same results as before:

$ mv todo.py todo
$ ./todo
Hello, world!
$

Excellent. Now we can start getting into clik proper.
