Go Scratch Mode

This is a little package for experimenting with Go code without having to use the Go Playground. Usage is simple: just write the code you want to play around with, C-c C-c, and then the program's stdout will be printed to the message area. Processes have 3 seconds (by default) to finish.

Caveats

• Unlike the Go playground, there's no sandboxing, so you can destroy your system if you try hard enough.
• godoc and godef functions don't work (since they want you to be visiting a file).
• Your go-mode hooks will run, and some minor modes don't like running without a file. company-go is an example; if you're running into problems, you might try something like the following:

(defun my-go-hook ()
  (when buffer-file-name
    (setq-local company-backends '(company-go))))

(add-hook 'go-mode-hook #'my-go-hook)
