Step 1 — Creating a simple Go program ///////////////////////////////////// └$ mkdir hello └$ cd hello
When importing packages, you have to manage the dependencies through the code’s own module. You can do this by creating a go.mod file with the go mod init command:
└$ go mod init hello (e ele "esta" na pasta hello)
Next, create a Hello, World! Go file in your preferred text editor: Add the following text into your hello.go file:
package main
import "fmt"
func main() { fmt.Println("Hello, World!") }
Test your code to check that it prints the Hello, World! greeting: └$ go run . // só tem este na pasta ... // only have "hello.go" in the directory
Output: Hello, World!
Step 2 — Building an Executable /////////////////////////////// The go run command ran the code for your “Hello, World!” program, but you may want to build your program into a binary to run anywhere on your system, not just from the source. The go build command builds executables.
└$ go build hello
