Trash - Go ./vendor manager

Keeping the trash in your ./vendor dir to a minimum.

How to use

Make sure you're using go1.6 or later version.

  1. Download and extract latest release to your PATH. Alternatively, install or update current development version with go get -u github.com/rancher/trash.
  2. Copy vendor.conf file to your project and edit to your needs.
  3. Run trash.

vendor.conf (in your project root dir) specifies the revisions (git tags or commits, or branches - if you're drunk) of the libraries to be fetched, checked out and copied to ./vendor dir. For example:

github.com/rancher/trash

github.com/Sirupsen/logrus                      v0.8.7    https://github.com/imikushin/logrus.git
github.com/codegangsta/cli                      b5232bb
github.com/cloudfoundry-incubator/candiedyaml   5a459c2

Or, in YML format:

import:
- package: github.com/Sirupsen/logrus               # package name
  version: v0.8.7                                   # tag or commit
  repo:    https://github.com/imikushin/logrus.git  # (optional) git URL

- package: github.com/codegangsta/cli
  version: b5232bb2934f606f9f27a1305f1eea224e8e8b88

- package: github.com/cloudfoundry-incubator/candiedyaml
  version: 55a459c2d9da2b078f0725e5fb324823b2c71702

Run trash to populate ./vendor directory and remove unnecessary files. Run trash --keep to keep all checked out files in ./vendor dir.

Inspiration

I really liked glide, it's like a real package manager: specify what you need, run glide up and enjoy your updated libraries. But it didn't help with a couple problems I had:

  • All necessary library code should be vendored and checked into project repo (as imposed by the project policy)
  • Unnecessary code should be removed for great justice for smaller git checkouts and faster docker build

I'd been slightly reluctant to the idea of writing it, but apparently the world needed another package manager: "Come on, it's just going to be 300 (okay, it's ~600) lines of Go!" Thanks to @ibuildthecloud for the idea.

Help

For the world's convenience, trash can detect glide.yaml (and glide.yml, as well as trash.yaml) and use that instead of vendor.conf (and you can Force it to use any other file). Just in case, here's the program help:

$ trash -h
