Use The %q Verb When Debugging In Go

I’m working on my twitter CLI and as I was writing a function to format the tweet I remembered something I picked up last week. After a quick search in my notes I remembered to use the %q with printf.

slice := []string{feed.Items[0].Title, feed.Items[0].Link}
result := strings.Join(slice, "\n")
fmt.Printf("Testing printf %q", result)

This is very useful when formatting output. Now I can actually see whether it is inserting the new line characters correctly:

Testing printf "I Made My First Tweet Using My Go Program\nhttps://mischavandenburg.com/zet/go-first-tweet/"I Made My First Tweet Using My Go Program

This can be harder to see when printing the variable using fmt.Println or using the %v verb with Printf.
