GoLang Packages How-To

Short and sweet tutorial on importing local packages

Create a folder, now inside of it run

go mod init mempool

next

mkdir -p maths/rands

now

touch maths/abs.go maths/rands/fermat.go run.go

you should have this

Populate your abs.go with this

package maths
import (
    "fmt"
)
func HelloWorld() {
    fmt.Println("Hello World");
}

Smack this into your fermat.go

package rands
import "mempool/maths"
func Main() {
    maths.HelloWorld();
}

finally, your run.go looks like this

package main
import "mempool/maths/rands"
func main() {
    rands.Main();
}

now, run go run . in the root directory. Well done!
