goenv

Create a new Go environment in the current working directory.

This will create the dirs bin, pkg and src, update $PATH to include the newly created bin dir and update $GOPATH to be the current working directory.

Why?

Using per-project dependencies removes the possibility of version conflicts between projects. If Project A requires package Xv1.0 and Project B requires package Xv2.0, but the required packages share an import name ("github.com/user/package"), it's impossible to have both dependencies installed in the same Go workspace without a headache.

One solution is to have a copy of each projects dependencies isolated from each other by modifying $PATH and $GOPATH if you switch projects.

This script makes that process of changing environment variables easier.

Installation

1. Download the script and put it on your $PATH (sometimes /usr/local/bin)

Usage

To create a new $GOPATH

1. $ mkdir new_gopath
2. $ cd new_gopath
3. $ . goenv

To update $GOPATH

1. $ cd existing_gopath
2. $ . goenv
