I'm Nick Wells. I write mostly Go code, mostly for the command line.

If you're looking for gosh see the utilities repository (I gave a talk about it at London Gophers)

• the gosh Go code runner - it allows you to write and run small Go programs from the command line
• various command-line tools to help you write Go code.
• a collection of Go modules. These work together and provide a lot of the functionality of gosh and the other tools
• the param package - a powerful and flexible parameter parsing package for Go
