从Go中的另一个包调用函数

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: How can I call a function from package main?

File 1: main.go (located in MyProj/main.go)

package main

import "fmt"
import "functions" // I dont have problem creating the reference here

func main(){
    c:= functions.getValue() // <---- this is I want to do
}

File 2: functions.go (located in MyProj/functions/functions.go)

package functions

func getValue() string{
    return "Hello from this another package"
}

Answer 1

You import the package by its import path, and reference all its exported symbols (those starting with a capital letter) through the package name, like so:

import "MyProj/functions"

functions.GetValue()
