PackageManagementTools.md

This page contains a list of tools for managing Go packages and their dependencies (vendoring). The tools are divided into categories based on their approach to version management.

To see popularity of these tools, click [here](https://github.com/blindpirate/report-of-build-tools-for-java-and-golang).

## dep tool

[dep](https://github.com/golang/dep), will be the *official* dependency tool. It is currently being implemented, in pre-alpha state and should be used with caution as "Lots of functionality is knowingly missing or broken".

## GO15VENDOREXPERIMENT

As of [June 19th, 2015](https://groups.google.com/d/msg/golang-dev/74zjMON9glU/EOKSoaL5p8wJ), the Go toolchain includes an experimental vendoring flag, `GO15VENDOREXPERIMENT`. This is now part of the Go 1.5 release and represents the Go team's recommended approach to vendoring dependencies. You can read more about how this environment variable works in the [Go 1.5 documentation](https://golang.org/cmd/go/#hdr-Vendor_Directories) and the [original design document](https://docs.google.com/document/d/1Bz5-UB7g2uPBdOx-rw5t9MxJwkfpx90cqG9AFL0JAYo/view). For a more detailed explanation, check out [this post](https://medium.com/@freeformz/go-1-5-s-vendor-experiment-fd3e830f52c3) by [@freeformz](https://twitter.com/freeformz) or [this short explainer](http://engineeredweb.com/blog/2015/go-1.5-vendor-handling/) from Engineered Web.

Go 1.6 release makes this behaviour the default, so you no longer need to have `GO15VENDOREXPERIMENT` set. Go 1.7 makes this a standard feature and removes support for this flag.

Tools supporting this feature include:

 * [dep](https://github.com/golang/dep)
 * [manul](https://github.com/kovetskiy/manul) - Vendor packages using git submodules.
 * [Godep](https://github.com/tools/godep)
 * [Govendor](https://github.com/kardianos/govendor)
 * [godm](https://github.com/hectorj/godm)
 * [vexp](https://github.com/kr/vexp)
 * [gv](https://github.com/forestgiant/gv)
 * [gvt](https://github.com/FiloSottile/gvt) - Recursively retrieve and vendor packages.
 * [govend](https://github.com/govend/govend) - Manage dependencies like `go get` but for `/vendor`.  
 * [Glide](https://github.com/Masterminds/glide) - Manage packages like composer, npm, bundler, or other languages.
 * [Vendetta](https://github.com/dpw/vendetta)
 * [trash](https://github.com/rancher/trash)
 * [gsv](https://github.com/toxeus/gsv)
 * [gom](https://github.com/mattn/gom)

## Pkg copy, built using GOPATH modification, supports fetching specific version

Copy packages locally. When building modify the GOPATH or use the GO 1.5 `GO15VENDOREXPERIMENT` to reference the local package store. Not only records specific version, but also fetches specific version.

## Revision Locking

Package source control versions are recorded. Versions are updated into the GOPATH package tree.
Requires switching GOPATH for every project.

## Pkg copy with import path re-write (As of Go 1.5, this is no longer the recommended practice)

Vendoring with import path rewriting takes the 3rd party source code that is referenced in your project and makes a copy of that code inside a new folder within the project. It re-writes the import paths so there is a single copy of all packages. GOPATH is not modified at any time.

## Import Proxies
Import Proxies act as a man in the middle between the Go tool and the VCS. It parses the data stream while the repository is being cloned.

## Go Version Managers
Go Version Managers allow you to have multiple versions of Go installed on your machine. It allows you to switch between those versions.
