Golang stuff for Logan

logan-golang.el

;; this could use some improvement
;;
;; - it doesn't clean up the temp file
;; - it doesn't ensure there's a selected region
;; - etc.

(defun logan/run-selected-golang-code ()
  "run the selected code as though it is golang code"
  (interactive)
  (let ((tempfile (format "%s.go" (make-temp-file "logan-golang"))))
    (write-region (region-beginning) (region-end) tempfile)
    (compile (format "go run %s" tempfile))))

;; if you add the above function and this following line into your
;; ~/.emacs (which is a lousy way of doing things) then you can
;; highlight some code, then run "C-x g r" to "go-run this region"
(global-set-key (kbd "C-x g r") 'logan/run-selected-golang-code))

Load that code up, then in an emacs buffer, paste in this:

here is a random buffer with some crap in it

Oh hang on, let's type some  go code
package main

import "fmt"

func main() {
fmt.Println("Hello, 世界")
}

Highlight the golang code, then run M-x logan/run-selected-golang-code
