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\"

Answer 1

go-semver is a semantic versioning library for Go. It lets you parse and compare two semantic version strings.

Example:

vA := semver.New("1.2.3")
vB := semver.New("3.2.1")

fmt.Printf("%s < %s == %t\n", vA, vB, vA.LessThan(*vB))

Output:

1.2.3 < 3.2.1 == true
