GVM provides an interface to manage Go versions.

• Install/Uninstall Go versions with gvm install [tag] where tag is "60.3", "go1", "weekly.2011-11-08", or "tip"
• List added/removed files in GOROOT with gvm diff
• Manage GOPATHs with gvm pkgset [create/use/delete] [name]. Use --local as name to manage repository under local path (/path/to/repo/.gvm_local).
• List latest release tags with gvm listall. Use --all to list weekly as well.
• Cache a clean copy of the latest Go source for multiple version installs.

When we started developing in Go mismatched dependencies and API changes plauged our build process and made it extremely difficult to merge with other peoples changes.

After nuking my entire GOROOT several times and rebuilding I decided to come up with a tool to oversee the process. It eventually evolved into what gvm is today.

To install:

bash < <(curl -s https://raw.github.com/moovweb/gvm/master/binscripts/gvm-installer)

gvm install go1
gvm use go1 [--default]

Once this is done Go will be in the path and ready to use. $GOROOT and $GOPATH are set automatically.

To list all installed Go versions (The current version is prefixed with "=>"):

gvm list

To completely remove gvm and all installed Go versions and packages:

gvm implode
