Story: Writing Scripts with Go

This is a story about how I tried to use Go for scripting. In this story, I’ll discuss the need for a Go script, how we would expect it to behave and the possible implementations; During the discussion I’ll deep dive to scripts, shells, and shebangs. Finally, we’ll discuss solutions that will make Go scripts work.

Why Go is good for scripting?

While python and bash are popular scripting languages, C, C++ and Java are not used for scripts at all, and some languages are somewhere in between.

Redux Chaos Monkey

This is a proof of concept which allows you to replay system events in a random order each time to make sure your UI can tolerate variable states.

I'm not sure if this is worthy of its on open source project with additional features like changing play back time, whitelisting/blacklisting actions etc but figured I'd put this out there to see if it piques anyones interest.

See a video of this in action here: [https://www.youtube.com/watch?v=wkoukONfwmA](Video on YouTube).
