I’m using go-mode and needed the following script to correctly guess my GOPATH:

(defun go-set-project-with-guard ()
  (let* ((g (go-guess-gopath))
          (d (concat (getenv "HOME") "/src/golang"))
          (r (concat (getenv "HOME") "/src:"))
          (has-match (string-match r g)))

    (if (not (eq 0 has-match))
        (setenv "GOPATH" d)
        (setenv "GOPATH" g))))

(eval-after-load 'go-mode
  '(add-hook 'go-mode-hook 'go-set-project-with-guard))

The problem with using go-mode’s script was that my default path for code is ~/src. Which means that go-guess-gopath will recurse up to the top of that path rather than remaining at ~/src/golang.

So I wrapped the script with my own fn to check if script returns incorrect pathing, and set it correctly if so.

PS - I’d prefer to use apply-partially here for concat '(getenv "HOME")' but didn’t get it working in 10 min and figured my time was better spent posting this blog entry.

Here’s the second installment, briefly covering installing RVM and an approachable text editor (Sublime Text 2). I advocate for focusing learning on one area at a time which means learn Ruby rather than starting to learn Ruby and VIM at the same time. (Learn VIM or EMACS once you’re further along with the language itself and see it as a long term investment in your productivity and happiness as a code crafter).
