Goenv – Go Environment Manager

To briefly explain what Goenv is, I will assume you have previously worked with Python. Basically it’s what Virtualenv is for Python. Goenv (and it’s wrapper goof) creates a folder for a new project and set the $GOPATH env variable to that folder path. At this point every time you do go get, the libraries will be installed in that specific $GOPATH.

It’s very important to use separate $GOPATH for each project, because this allow us to use different library versions for each project and avoid version conflicts.

Installation

Goenv is now installed, we will now install its wrapper goof:

Edit .bashrc (or .zshrc if you use zsh) and append these lines:

How to use it

To create a new go environment use make:

To exit the go environment use deactivate:

To use an environment use workon:

To show available environments use show:

Goenv itself is not enough to manage Go packages. It would be like using Virtualenv only and not using pip and requirements. In a future post I will explain how to use Godep.
