# Versioning Library for Go
|
|
[](https://travis-ci.org/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))
|
|
```
|
|
