Here’s a short tutorial to help you get started with Go (aka Golang):
- Install Go: Go can be downloaded and installed from the official website. Once installed, you can verify your installation by running the “go version” command in your terminal.
- Set up your workspace: Go uses a specific directory structure for your code, known as a workspace. Within your workspace, you should create a directory called “src” to store your source code, and a directory called “bin” to store the compiled executable files. You can set up your workspace by creating these directories and setting the GOPATH environment variable to the root directory of your workspace.
- Write your first program: Create a new file in the “src” directory and call it “hello.go”. In this file, type the following code:
goCopy codepackage main
import "fmt"
func main() {
fmt.Println("Hello, World!")
}
This program uses the “fmt” package to print a greeting to the console. The “main” function is the entry point of the program, and is executed when the program is run.
- Build and run your program: In your terminal, navigate to the directory containing “hello.go”. To build the program, run the command “go build”. This will compile the program and create an executable file in the “bin” directory. To run the program, simply run the executable file with the command “./hello”.
- Learn more about Go: Go has many features and libraries that make it a powerful language for a wide range of applications. Some key areas to explore include concurrency, networking, and web development. The official Go website has many resources for learning more about the language, including documentation, tutorials, and examples.
By following these steps, you can quickly get up and running with Go and start exploring its powerful features and benefits. Whether you’re a beginner or an experienced programmer, Go is a language that is well worth learning and using for your next project.
