go-pacman-version

A Go library for parsing pacman package versions

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

The implementation is based on vercmp(8), this implementation

OS: Arch Linux

Installation and Usage

Installation can be done with a normal go get:

$ go get github.com/MaineK00n/go-pacman-version

Version Parsing and Comparison

import version "github.com/MaineK00n/go-pacman-version"

v1, err := version.NewVersion("5.1.004-1")
v2, err := version.NewVersion("5.1.008-1")

// 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{"5.1.008-1", "5.1.0-2", "5.1.004-1", "5.1.0-1"}
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])
})
