go-deb-version

A Go library for parsing package versions

go-deb-version is a library for parsing and comparing versions

Versions used with go-deb-version must follow deb-version (ex. 2:6.0-9ubuntu1)
The implementation is based on Debian Policy Manual

OS: Debian, Ubnutu

Installation and Usage

Installation can be done with a normal go get:

$ go get github.com/knqyf263/go-deb-version

Version Parsing and Comparison

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

v1, err := version.NewVersion("2:6.0-9")
v2, err := version.NewVersion("2:6.0-9ubuntu1")

// Comparison example. There is also GreaterThan, Equal.
if v1.LessThan(v2) {
    fmt.Printf("%s is less than %s", v1, v2)
}

Version Sorting

raw := []string{"7.4.052-1ubuntu3.1", "7.4.052-1ubuntu3", "7.1-022+1ubuntu1", "7.1.291-1", "7.3.000+hg~ee53a39d5896-1"}
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])
})
