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]
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.

Background

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.

Installing

To install:

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

Installing Go

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.

You are now ready to create and use packages built using gpkg. Instructions can be found at http://github.com/moovweb/gpkg

List Go Versions

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

gvm list

Uninstalling

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

gvm implode

If that doesn't work see the troubleshooting steps at the bottom of this page.
