Version Parsing and Comparison

import "github.com/knqyf263/go-apk-version"

v1, err := version.NewVersion("1.2.3")
v2, err := version.NewVersion("1.2.3-r1")

// Comparison example. You can use GreaterThan and Equal as well.
if v1.LessThan(v2) {
    fmt.Printf("%s is less than %s", v1, v2)
}

Version Sorting

raw := []string{"1.2.3", "1.2.3_alpha1", "1.2.3-r1", "1.2.4", "1.0_p9-r0"}
vs := make([]version.Version, len(raw))
for i, r := range raw {
	v, _ := version.NewVersion(r)
	vs[i] = v
}

sort.Slice(vs, func(i, j int) bool {
	return vs[i].LessThan(vs[j])
})
