## Go
|
|
|
|
|
|
**Go** (or **golang**) is a programming language created at Google in 2007 by Robert Griesemer, Rob Pike, and Ken Thompson. It is a compiled, statically-typed language in the tradition of Algol and C. It has garbage collection, limited structural typing, memory safety, and CSP-style concurrent programming features added. The compiler and other language tools originally developed by Google are all free and open source. Its popularity is increasing fast. It is a great choice for building web applications.

## Pre-Installations:
|
|
-----------
|
|
|
|
#### Install Golang with Homebrew:
|
|
|
|
```bash
|
|
$ brew update
|
|
$ brew install golang
|
|
```
|
|
#### When installed, try to run go version to see the installed version of Go.
|
|
|
|
### Setup the workspace:
|
|
------
|
|
|
|
##### Add Environment variables:
|
|
|
|
First, you will need to tell Go the location of your workspace.
|
|
|
|
You will add some environment variables into shell config. One of those files is located in your home directory bash_profile, bashrc or .zshrc (for Oh My Zsh Army)
|
|
|
|
```bash
|
|
$ vi .bashrc
|
|
````
|
|
|
|
then add those lines to export the required variables
|
|
|
|
#### This is actually your .bashrc file
|
|
|
|
```bash
|
|
export GOPATH=$HOME/go-workspace # don't forget to change your path correctly!
|
|
export GOROOT=/usr/local/opt/go/libexec
|
|
export PATH=$PATH:$GOPATH/bin
|
|
export PATH=$PATH:$GOROOT/bin
|
|
```
|
|
|
|
#### Create your workspace:
|
|
--------
|
|
##### Create the workspace directories tree:
|
|
```bash
|
|
$ mkdir -p $GOPATH $GOPATH/src $GOPATH/pkg $GOPATH/bin
|
|
$GOPATH/src : Where your Go projects / programs are located
|
|
$GOPATH/pkg : contains every package objects
|
|
$GOPATH/bin : The compiled binaries home
|
|
```
|
|
|
|
### Quickstart
|
|
