Golang noob here trying to create a basic standalone package.
The package code is simple and is given below:
package Utils
import (
"bufio"
"os"
)
func ReadLine() string {
scanner := bufio.NewScanner(os.Stdin)
scanner.Scan()
return scanner.Text()
}
It works as expected but I get a editor warning (I am using Jetbrains
Gogland) "Unused function 'ReadLine'". However if I change the function
name to something like Read instead of ReadLine I don't get the warning.
Can someone kindly explain why this happens?
Also, what needs to be done to get rid of this "unused function" warning
while creating standalone packages. If I understand correctly, an exposed
function in a package is supposed to be invoked by the package consumer and
is unlikely to be used inside the package itself.
A reference to the Golang documentation where these topics are explained
would be greatly appreciated.
