The original contents of `vendor` were inadvertently captured with an older version of `godep`. Here, we recapture dependencies by running the following: ``` godep restore -v cat Godeps/Godeps.json | jq -r '.Deps[].ImportPath' | xargs godep update -v ``` The newer godep makes the following changes as it captures dependencies: * Skips test files * Copies `LICENSE` / `PATENTS` files There is also an additional diff in `golang.org/x/sys/unix` that looks very similar to the diff between `master..c65f27f` in that repo, so I'm guessing that dependency was accidentally captured from master instead of the commit saved to `Godeps.json`. All in all, these changes should all be "more correct" and result in smaller diffs for any future updates made to dependencies. |

Versioning Library for Go
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.
Installation and Usage
Package documentation can be found on GoDoc.
Installation can be done with a normal go get:
$ go get github.com/hashicorp/go-version
Version Parsing and Comparison
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
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
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))
