How to compare two version number strings in golang

Question

I have two strings (they are actually version numbers and they could be any version numbers)

a := "1.05.00.0156"   b := "1.0.221.9289" 

I want to compare which one is bigger. How to do it in golang?

There is a nice solution from Hashicorp - https://github.com/hashicorp/go-version

import github.com/hashicorp/go-version v1, err := version.NewVersion("1.2") v2, err := version.NewVersion("1.5+metadata") // Comparison example. There is also GreaterThan, Equal, and just // a simple Compare that returns an int allowing easy >=, <=, etc. if v1.LessThan(v2) {     fmt.Printf("%s is less than %s", v1, v2) }
