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)](https://archlinux.org/pacman/vercmp.8.html), [this implementation](https://gitlab.archlinux.org/pacman/pacman/-/blob/master/lib/libalpm/version.c#L219-260)

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])

})

```
