<p><strong><a href="http://github.com/simonw/optfunc">optfunc</a></strong></p> Command line parsing libraries in Python such as optparse frustrate me because I can never remember how to use them without consulting the manual. optfunc is a new experimental interface to optparse which works by introspecting a function definition (including its arguments and their default values) and using that to construct a command line argument parser. Feedback and suggestions welcome! <p>Tags: <a href="https://simonwillison.net/tags/cli">cli</a>, <a href="https://simonwillison.net/tags/github">github</a>, <a href="https://simonwillison.net/tags/introspection">introspection</a>, <a href="https://simonwillison.net/tags/optfunc">optfunc</a>, <a href="https://simonwillison.net/tags/optparse">optparse</a>, <a href="https://simonwillison.net/tags/projects">projects</a>, <a href="https://simonwillison.net/tags/python">python</a></p>
