Emacs - No line numbering for empty lines

Question

I'm trying to setup line numbering in Emacs.
Linum works well, but when I open two buffers, numbering for empty lines disappears. I use Manjaro Linux. Emacs works in the terminal.

Here's screenshot.

Code from .emacs file:

(add-hook 'find-file-hook (lambda () (linum-mode 1)))

(unless window-system
  (add-hook 'linum-before-numbering-hook
    (lambda ()
      (setq-local linum-format-fmt
          (let ((w (length (number-to-string
                (count-lines (point-min) (point-max))))))
            (concat "%"(number-to-string w) "d"))))))

(defun linum-format-func (line)
  (concat
   (propertize (format linum-format-fmt line) 'face 'linum)
   (propertize " " 'face 'mode-line)))

(unless window-system
  (setq linum-format 'linum-format-func))

How can I fix it?

See: http://stackoverflow.com/a/25082664/2112489 and http://emacs.stackexchange.com/a/4179/2287 Perhaps one of them applies. — lawlist, Jul 21 '16 at 18:40

You might be able to fix this by replacing all of the above code with just
```
(global-linum-mode 1)
```
linum-mode should already do the variable-size-format thing for you. Don't know why you're reinventing the wheel.

Maybe your problem is that you're trying to string concat two propertize-d objects. You can avoid this by making your formatting like "%3d " instead of "%3d" and concatting " " later:

(add-hook 'find-file-hook (lambda () (linum-mode 1)))

(unless window-system
  (add-hook 'linum-before-numbering-hook
    (lambda ()
      (setq-local linum-format-fmt
          (let ((w (length (number-to-string
                (count-lines (point-min) (point-max))))))
            (concat "%" (number-to-string w) "d "))))))

(defun linum-format-func (line)
  (propertize (format linum-format-fmt line) 'face 'linum))

(unless window-system
  (setq linum-format 'linum-format-func))
