Emacs compile ignoring compile-command variable

Question

Initially, I had the following defined in my .emacs.d/init.el

(defun go-mode-setup ()
  (setq compile-command "go build -v && go test -v && go vet && golint")
  (define-key go-mode-map (kbd "C-c C-c") 'compile)
  )

While in go-mode, everything else seemed to work fine, but his did not seem to set or respect my Cc Cc command, instead producing

C-c C-c is undefined.

So, I added an explicit hook:

(add-hook 'go-mode-hook (lambda () (define-key go-mode-map (kbd "C-c C-c") 'compile)))

This now respects my Cc Cc kbd shortcut, but still ignores the compile-command I set. Unfortunately, it seems to compile the entire folder rather than just the main.go file I am working on.

Compile command: make -k 

How can I set Cc Cc to use the compile-command I set?

Answer 1

Your code works for me. The only thing missing is an add-hook . You probably want to set the compile-command to be buffer-local as well.

Here's my code that definitely works:

(defun jpk/go-mode-hook ()
  (make-local-variable 'compile-command)
  (setq compile-command "go build -v")
  (define-key go-mode-map (kbd "C-c C-c") #'compile))
(add-hook 'go-mode-hook #'jpk/go-mode-hook)

I strongly recommend against redefining compile like in @jdc's answer. If you must define your own command, do it with a different name.

You may want to check out the multi-compile package, it allows you to set multiple compile commands (optionally major-mode specific).

This should work:

(add-hook 'go-mode-hook (lambda ()
  (defun compile ()
    (setq compile-command "go build -v && go test -v && go vet && golint"))
  (define-key go-mode-map (kbd "C-c C-c") 'compile)))
