# go-deb-version
[](https://travis-ci.org/knqyf263/go-deb-version)
[](https://coveralls.io/github/knqyf263/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](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])
})
```
