# Versioning Library for Go
[](https://godoc.org/github.com/hashicorp/go-version)
go-version is a library for parsing versions and version constraints,
and verifying versions against a set of constraints. go-version
can sort a collection of versions properly, handles prerelease/beta
versions, can increment versions, etc.
Versions used with go-version must follow [SemVer](http://semver.org/).
## Installation and Usage
Package documentation can be found on
[GoDoc](http://godoc.org/github.com/hashicorp/go-version).
Installation can be done with a normal `go get`:
```
$ go get github.com/hashicorp/go-version
```
#### Version Parsing and Comparison
```go
v1, err := version.NewVersion("1.2")
v2, err := version.NewVersion("1.5+metadata")
// Comparison example. There is also GreaterThan, Equal, and just
// a simple Compare that returns an int allowing easy >=, <=, etc.
if v1.LessThan(v2) {
fmt.Printf("%s is less than %s", v1, v2)
}
```
#### Version Constraints
```go
v1, err := version.NewVersion("1.2")
// Constraints example.
constraints, err := version.NewConstraint(">= 1.0, < 1.4")
if constraints.Check(v1) {
fmt.Printf("%s satisfies constraints %s", v1, constraints)
}
```
#### Version Sorting
```go
versionsRaw := []string{"1.1", "0.7.1", "1.4-beta", "1.4", "2"}
versions := make([]*version.Version, len(versionsRaw))
for i, raw := range versionsRaw {
v, _ := version.NewVersion(raw)
versions[i] = v
}
// After this, the versions are properly sorted
sort.Sort(version.Collection(versions))
```
