Hello Gophers! Today, we’re going to talk about the installation and setup of Go, the programming language that has been gaining popularity in recent years due to its simplicity and efficiency.
I know what you’re thinking: “Jeremy, setting up a programming language can be a real pain. Do we really need to go through this?” And the answer is: yes, you do. But don’t worry.
We’re here to guide you through every step of the way.
First things first, let’s talk about installation. The good news is that Go is easy to install, and you don’t need any special tools or software to start. Head over to the Go website, download the latest version of the Go compiler for your operating system and follow the installation instructions.
Once you have Go installed, it’s time to set up your development environment. This is where things get a little more complex, but don’t worry. We’re here to help.
If you’re using a text editor or integrated development environment (IDE), you must configure it to work with Go. Most popular text editors and IDEs have plugins or extensions that make it easy to work with Go. For example, if you’re using Visual Studio Code, you can install the Go extension from the Visual Studio Marketplace. This extension provides syntax highlighting, autocompletion, and other useful features.
If you prefer to work from the command line, you must set up your environment variables. This will tell your operating system where to find the Go tools and libraries.
The exact steps will vary depending on your operating system, but here’s an example for Linux:
Open your terminal and type the following command:
export PATH=$PATH:/usr/local/go/bin
Next, create a new directory for your Go workspace:
mkdir ~/go
Finally, set the GOPATH environment variable to point to your new workspace:
export GOPATH=~/go
And that’s it! You’re now ready to start coding in Go. To test your installation, open a new file in your text editor or IDE, and type the following code:
package main
import "fmt"
func main() {
fmt.Println("Hello, world!")
}
Save the file as hello.go, and then open your terminal and navigate to the directory where you saved the file. Type the following command to compile and run the program:
go run hello.go
You should see the message “Hello, world!” printed in your terminal.
Congratulations, you have successfully installed and set up Go! Now it’s time to start exploring the language and all the amazing things you can do with it.
Thanks for reading, and happy coding!
