Manage repos in varying version control systems with ease through a common interface.

Quick usage:

remote := "https://github.com/Masterminds/vcs"
local, _ := ioutil.TempDir("", "go-vcs")
repo, err := NewRepo(remote, local)

In this case NewRepo will detect the VCS is Git and return a GitRepo. All of the repos implement the Repo interface with a common set of features between them.

Git, SVN, Bazaar (Bzr), and Mercurial (Hg) are currently supported. They each have their own type (e.g., GitRepo) that follow a simple naming pattern. Each type implements the Repo interface and has a constructor (e.g., NewGitRepo). The constructors have the same signature as NewRepo.

• Clone or checkout a repository depending on the version control system.
• Pull updates to a repository.
• Get the currently checked out commit id.
• Checkout a commit id, branch, or tag (depending on the availability in the VCS).
• Get a list of tags and branches in the VCS.
• Check if a string value is a valid reference within the VCS.

The package golang.org/x/tools/go/vcs provides some valuable functionality for working with packages in repositories in varying source control management systems. That package, while useful and well tested, is designed with a specific purpose in mind. Our uses went beyond the scope of that package. To implement our scope we built a package that went beyond the functionality and scope of golang.org/x/tools/go/vcs.
