Call a function from another package in Go

Question

I have two files main.go which is under package main, and another file with some functions in the package called functions.

My question is:

Answer 1

you can write

import(
  functions "./functions" 
)
func main(){
  c:= functions.getValue() <-
}

If you write in gopath write this import functions "MyProj/functions" or if you are working with Docker
