git-vendor
==========
A work in progress git command for managing golang vendor dependencies.

`git-vendor` is a wrapper around `git-subtree` commands for checking out and updating vendored dependencies.

`git-vendor` provides the following commands:

* `git vendor add <repository> <ref>` - add a new vendored dependency in `vendor/`
* `git vendor list` - list all current vendored dependencies, their source, and current vendored ref.
* `git vendor update <dir> <ref>` - update a vendored dependency to `<ref>`.

## Installation
Manually:

```bash
git clone https://github.com/brettlangdon/git-vendor
cd ./git-vendor
make
```

One-liner:
```bash
curl -sSL https://git.io/vz8AK | sudo bash /dev/stdin
```
