In order to learn D, I've worked up a port of the docopt commandline parser (original in Python http://docopt.org).
https://github.com/rwtolbert/docopt.d Since this is my first code in D, I apologize in advance for the mix if Python and C++ idioms. Since this is ported from Python, with the intention of staying compatible with future Python versions, some of that is expected, but I look for this as an chance to learn more about D. It is also a pretty useful way to write commandline interfaces. The included example that mimics the git CLI is pretty impressive. This is also my first submission as a dub project, so hopefully I got that right as well. Still needs more tests ported from Python, but it does pass the entire functional test suite for the current Python version. Regards, Bob
