For those of you that haven't heard of jsonnet (like me 3 days ago), its an extension of JSON which can use logic and functions to template out data. I was exposed to it when our company upgraded our DroneCI instance to 1.0, which requires a new yaml config format. Their docs recommended using jsonnet, but for the life of me, I could not find a way to compile that jsonnet on windows. All my searches turned up instructions to brew install jsonnet, or libraries to handle the jsonnet in code. I decided to use one of those libraries (thanks @rbicker!) and create a simple CLI tool that would work across platforms.

I hope you like it, and here are the relevant links to the libraries and technologies used:
