Introduction

Before you can start programming in Go, you need to set up your development environment. In this guide, we'll walk you through the process of installing Go, configuring your workspace, and getting ready to write and run Go code.


Installing Go

The first step is to install the Go programming language on your system. You can download the latest Go distribution for your operating system from the official Go website.

                            <!-- Sample code for installing Go on Linux -->
                $ wget https://golang.org/dl/go1.17.2.linux-amd64.tar.gz
                $ tar -C /usr/local -xzf go1.17.2.linux-amd64.tar.gz
                $ export PATH=$PATH:/usr/local/go/bin

After installation, verify that Go is correctly installed by running:

                            $ go version

Configuring Your Workspace

Go uses a specific directory structure for your workspace. By default, your workspace is located at $HOME/go. Within this directory, you should organize your code in a specific way:

                            go/
                ├── bin/         # Compiled binaries
                ├── pkg/         # Package objects
                └── src/         # Go source code

You can set your Go workspace by defining the GOPATH environment variable:

                            export GOPATH=$HOME/go

Your First Go Program

Let's create a simple "Hello, World!" program to ensure your Go environment is correctly set up. Create a file named hello.go with the following content:

                            package main
                import "fmt"
                func main() {
                    fmt.Println("Hello, Go!")
                }

You can compile and run this program using the following commands:

                            $ go build hello.go
                $ ./hello

If you see "Hello, Go!" printed on your screen, your Go development environment is set up correctly.


Choosing a Code Editor

Go can be developed with a variety of code editors and integrated development environments (IDEs). Some popular choices include Visual Studio Code with the Go extension, GoLand, and Atom. Choose an editor that suits your preferences and provides Go-specific tools and features.
