Setting up Vim as your Go IDE

Intro

I've been wanting to do a serious project in Go. One thing holding me back has been a my working environment. As a huge PyCharm user, I was hoping the Go IDE plugin for IntelliJ IDEA would fit my needs. However, it never felt quite right. After a previous experiment a few years ago using Vim, I knew how powerful it could be if I put in the time to make it so. Luckily there are plugins for almost anything you need to do with Go or what you would expect form and IDE. While this is no where near comprehensive, it will get you writing code, building and testing with the power you would expect from Vim.

Getting Started

I'm assuming you're coming with a clean slate. For me this was OSX so I used MacVim. There is nothing in my config files that assumes this is the case.

  nullary `bind-port!-fn` (which must return logical true on successful
