go-semver is a semantic versioning library for Go. It lets you parse and compare two semantic version strings.
vA, err := semver.NewVersion("1.2.3")
vB, err := semver.NewVersion("3.2.1")
fmt.Printf("%s < %s == %t\n", vA, vB, vA.LessThan(*vB))
$ go run example.go 1.2.3 3.2.1
1.2.3 < 3.2.1 == true
$ go run example.go 5.2.3 3.2.1
5.2.3 < 3.2.1 == false
- Richer comparision operations
