Go Package

Suppose we want to create a simple Go project that prints “Hello world” and prints the list of the arguments passed.

Let’s create the project:

go mod init github.com/my-cli

Now, let’s create our main.go:

touch main.go

And add the content:

main.go

package main

import (
	"fmt"
	"os"
)

func main() {
	fmt.Println("Hello, World!")

	fmt.Println("\n--------Args-------")
	for _, arg := range os.Args {
		fmt.Println("- " + arg)
	}
	fmt.Println("----end of args----\n")
}

If we run this program with Go:

go run . --flag --another flag

We’ll have something like this:

Hello, World!

--------Args-------
- /var/folders/xp/ctz4hzmj66d5sz29pgpvlnjm0000gn/T/go-build715925125/b001/exe/my-cli
- --flag
- --another
- flag
----end of args----

Cool. Now, let’s release this for all platforms.
