Golang : Trim everything onward after a word

Putting this simple example here for my own future reference. Basically, the problem that I'm trying to solve is to get rid of the rest from from a sentence after a word.

For example, I want to get rid of everything from "abc" onward. How to do that?

BEFORE :

s := "123123123123123456abc789123123123123"

AFTER :

s := "123123123123123456"

The solution is to use strings.LastIndex() to get the position of abc and then only capture the part before the position.

 package main

 import (
  "fmt"
  "strings"
 )

 func main() {
  s := "123123123123123456abc789123123123123"

  position := strings.LastIndex(s, "abc")

  fmt.Println(s[:position])
 }

Hope this help!

Happy computing!
