A Go library for parsing rpm package versions

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

For the original C implementation, see:
https://github.com/rpm-software-management/rpm/blob/master/lib/rpmvercmp.c#L16

OS: RedHat/CentOS

# Installation and Usage

Installation can be done with a normal go get:

```
$ go get github.com/knqyf263/go-rpm-version
```

## Version Parsing and Comparison

```
import "github.com/knqyf263/go-rpm-version"

v1, err := version.NewVersion("2:6.0-1")
v2, err := version.NewVersion("2:6.0-2.el6")

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

## Version Sorting

```
raw := []string{"5.3p1-112", "3.6.1p2-21.sel", "3.6.1p2-22", "5.3p1-105", "3.6.1p2-21"}
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])
})
```
