TLDR: I made a gem, required_arg which offers a workflow for requiring keyword arguments in Ruby 2.0.0, which doesn’t support them on the language level.

Why would you write this:

Last month, we looked at Ruby operators, and I complained about how I wish I could define my own operators. Today I’m looking at them a little more, and thinking about how Ruby handles expressions made up of multiple operations.

I like that you or I can write command line utilities in any language, name it git-butterfly, or whatever you want, and then run it as though it were an official part of the git tool, as git butterfly.

A while back I saw this cool blog post: Stay up to date with the latest github pages gem by Parker Moore, who maintains Jekyll. Jekyll is the static site tool that powers github pages, but github pages doesn’t necessarily use the latest version of Jekyll. If you’re deploying your website to github pages, you probably want to make sure your local Jekyll server behaves in the same way as the Jekyll that runs on github pages.
