eselect go

Manage multiple Go versions using Gentoo's eselect.

Usage

This tool is intended for use in the CoreOS SDK in order to support packages or architectures that cannot upgrade to the same Go version all at the same time. Gentoo doesn't support this use case.

Go is expected to be installed to /usr/lib/go1.5, /usr/lib/go1.6, etc. The go and gofmt binaries /usr/bin are actually wrappers and select which version to execute based on the EGO environment variable, the selection made by eselect go, or the latest version found.

$ eselect go
Usage: eselect go <action> <options>

Standard actions:
  help                      Display help text
  usage                     Display usage information
  version                   Display version information

Extra actions:
  list                      List installed Go versions
  set <target>              Set main active Go version
  show                      Show main active Go version
  update                    Switch to the latest Go version
    --if-unset                Do not override existing selection
    --ignore SLOT             Ignore SLOT when setting symlinks

Switch the default Go version:

$ eselect go set go1.6
$ go version
go version go1.6.3 linux/amd64

Override the default in the environment:

$ export EGO=go1.5
$ go version
go version go1.5.3 linux/amd64
