9. Go Packages Continued

Let's use our new mystrings package in hellogo.

Assignment

1

Modify hellogo's main.go

• Modify hellogo's main.go file with the below code. Don't forget to replace {REMOTE} and {USERNAME} with the values you used before.

package main

import (
	"fmt"

	"{REMOTE}/{USERNAME}/mystrings"
)

func main() {
	fmt.Println(mystrings.Reverse("hello world"))
}

2

Update hellogo's go.mod to use the local mystrings

• Follow this example to update hellogo's go.mod file to import the local version of the mystrings dependency:

module example.com/username/hellogo

go 1.25.1

replace example.com/username/mystrings v0.0.0 => ../mystrings

require example.com/username/mystrings v0.0.0

../mystrings tells go to look in the parent directory of hellogo for the mystrings sibling directory.

3

Build and run the program

• Build and run the new program:

go build
./hellogo

Run and submit the CLI tests from the root of the main package.
