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.

The Elements of Programming Style

The following rules of programming style are excerpted from the book "The Elements of Programming Style" by Kernighan and Plauger, published by McGraw Hill. Here is quote from the book: "To paraphrase an observation in The Elements of Style by Strunk and White, the rules of programming style, like those of English, are sometimes broken, even by the best writers. When a rule is broken, however, you will usually find in the program some compensating merit, attained at the cost of the violation. Unless you are certain of doing as well, you will probably do best to follow the rules."

#Model 

@user.should have(1).error_on(:username) # Checks whether there is an error in username 
@user.errors[:username].should include("can't be blank")  # check for the error message 

#Rendering
response.should render_template(:index)

#Redirecting 
response.should redirect_to(movies_path)

Preface

Below are the steps I took to install ffmpeg, ffmpegthumbnailer, and heroku to use with carrierwave-video and carrierwave-video-thumbnailer gems on my heroku app. I found there was no documentation to do exactly this, so I hope this is helpful for other people (and will save them the countless hours it took me to finally get it to work)

• carrierwave-video gem: https://github.com/rheaton/carrierwave-video
• carrierwave-video-thumbnailer gem: https://github.com/evrone/carrierwave-video-thumbnailer

These are the libraries you will end up installing to get all of this to work.
