Golang : Read until certain character to break for loop

Encounter a situation where I need to tell the editor that is time to save the input and exit while working on the previous tutorial to show how to create a simple text based editor to accept screen input and save the content directly into a file.

Basically, I need to tell the program when to stop scanning or reading from the input source and break the for loop.

To do that... just intercept input from scanner.Text() and if it matches the criteria, break the for loop.

Code fragment from https://www.socketloop.com/tutorials/golang-text-file-editor-accept-input-from-screen-and-save-to-file

 var userInput []string
 scanner := bufio.NewScanner(os.Stdin)

 for scanner.Scan() {
 line := scanner.Text()
 if line == "." {
 break // to stop writing enter . (period) and press enter
 userInput = append(userInput, line+"\n")
