I started with brew install go and the Go VSCode plugin.
I had to modify PATH and set GOPATH and GOROOT to make the sublime go plugin to work.
export GOROOT="$(brew --prefix golang)/libexec"
export PATH="$PATH:${GOROOT}/bin"
export GOPATH="${HOME}/.go"
As this document says, you only need to set one GOPATH. I created that using this one-time shell command, after defining GOPATH as described above:
test -d "${GOPATH}" || mkdir "${GOPATH}"

After this, I can run simple Go scripts directly in Sublime edit by usin the ⌘B key-chord.
I use my tried-and-trusted Travis CI for this repo. See the .travis.yml for the configuration.
