The Evolution of Finger: configuration of the finger service

Introduction

This is the eleventh part of the Twisted tutorial :doc:`Twisted from Scratch, or The Evolution of Finger <index>` .

In this part, we make it easier for non-programmers to configure a finger server. Plugins are discussed further in the :doc:`Twisted Plugin System <../plugin>` howto. Writing twistd plugins is covered in :doc:`Writing a twistd Plugin <../tap>`, and .tac applications are covered in :doc:`Using the Twisted Application Framework <../application>`.

Plugins

So far, the user had to be somewhat of a programmer to be able to configure stuff. Maybe we can eliminate even that? Move old code to finger/__init__.py and...

Full source code for finger module here:

:download:`finger.py <listings/finger/finger/finger.py>`

.. literalinclude:: listings/finger/finger/finger.py

:download:`tap.py <listings/finger/finger/tap.py>`

.. literalinclude:: listings/finger/finger/tap.py

And register it all:

:download:`finger_tutorial.py <listings/finger/twisted/plugins/finger_tutorial.py>`

.. literalinclude:: listings/finger/twisted/plugins/finger_tutorial.py

Note that the second argument to :py:class:`ServiceMaker <twisted.application.service.ServiceMaker>` ,``finger.tap`` , is a reference to a module (finger/tap.py ), not to a filename.

And now, the following works

% sudo twistd -n finger --file=/etc/users --ircnick=fingerbot
