Drush version control system, to manage a variety of Drush versions and provide the ability to switch to specific versions at any time.

It has been rewritten in Google's Golang as a pilot for the core maintainer to learn a new language and see what it would hold in professional development. It wasn't intended to stick or be released however the pilot program was extremely stable and efficient and it didn't make sense not to release it.

DVM will require the following to be available in the system depending on what you're trying to do:

• composer
• unzip
• wget

There are three ways to install DVM, but if you're at all familiar with Golang these are very standardised shipping methods.

1. run go get -u github.com/fubarhouse/dvm
2. Use like any other Go binary.

1. run go get -u github.com/fubarhouse/dvm
2. Build your own Go binary using the API's from the packages downloaded.

1. Download one of the pre-compiled binaries.
2. Copy to location in $PATH environment variable.

Configurations are loaded via Viper, an example is below.

The default values are in this example and should be overriden in ~/.dvm/config.toml to suit your system.

[config]
path = "/usr/local/bin/drush"

dvm install 7.2.0

dvm uninstall 7.2.0

dvm use 7.2.0

dvm list available

dvm list installed

dvm package install registry_rebuild

dvm package list
