The official Go code repository uses mercurial, but a reasonably
|
|
up-to-date git mirror is available at https://github.com/tav/go.git.
|
|
To use the git mirror for Go builds, use the --use-git-head option.
|
|
|
|
In order to use Go, set the following in your ~/.profile:
|
|
|
|
export GOROOT=`brew --prefix go`
|
|
export GOBIN=#{HOMEBREW_PREFIX}/bin
|
|
export GOARCH=#{which_arch}
|
|
export GOOS=darwin
|
|
|
|
Presumably at some point the Go developers won't require us to
|
|
mutilate our shell environments in order to compile Go code...
