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](http://man.he.net/man5/deb-version) (ex. 2:6.0-9ubuntu1)  

The implementation is based on [Debian Policy Manual](https://www.debian.org/doc/debian-policy/ch-controlfields.html#s-f-Version)

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])

})

```
