How Can Go's `go-version` Library Efficiently Compare Version Number Strings?

Comparing Version Number Strings in Go

Determining the relative size of version numbers is a common task in software development. In Go, you can use the go-version library from HashiCorp to easily compare version strings.

The syntax for go-version is as follows:

import (
  "fmt"

  "github.com/hashicorp/go-version"
)

To compare two version strings, you can create Version objects using the NewVersion function:

v1, _ := version.NewVersion("1.05.00.0156")
v2, _ := version.NewVersion("1.0.221.9289")

You can then use the following comparison operators:

• LessThan: Returns true if v1 is less than v2.
• GreaterThan: Returns true if v1 is greater than v2.
• Equal: Returns true if v1 is equal to v2.

For example:

if v1.LessThan(v2) {
  fmt.Printf("%s is less than %s", v1, v2)
}
