How to have both fixed linum and relative linum?

Question

I installed linum relative with this. But installing this replaced my fixed linum. I want to have both fixed line number and relative line number as well. How can I do this?

Answer 1

The following links linum wiki and stackoverflow similar issue help me to reach a solution with the following code :

(require 'linum) 
(add-hook 'prog-mode-hook 'linum-mode)
(defvar my-linum-format-string "%3d")

(add-hook 'linum-before-numbering-hook 'my-linum-get-format-string)

(defun my-linum-get-format-string ()
  (let* ((width (1+ (length (number-to-string
                             (count-lines (point-min) (point-max))))))
         (format (concat "%d (%" (number-to-string width) "d)")))
    (setq my-linum-format-string format)))

(defvar my-linum-current-line-number 0)

(setq linum-format 'my-linum-relative-line-numbers)

(defun my-linum-relative-line-numbers (line-number)
  (let ((offset (- line-number my-linum-current-line-number))
        (current (line-number-at-pos)))
    (propertize (format my-linum-format-string current offset) 'face 'linum)))

(defadvice linum-update (around my-linum-update)
  (let ((my-linum-current-line-number (line-number-at-pos)))
    ad-do-it))
(ad-activate 'linum-update)

It will show in the right column the absolute number of the line and in parenthesis the relative number in regard to the current line.

izkons's comment above seems like an answer to me...

I just use https://github.com/scottjad/linum-relativenumber which does it all. – izkon

Some caveat's about this solution:

• This modifies linum settings so might not respect customizations
• This might require a restart or a bunch of fiddling to switch off disable relative line numbers while keeping absolute line numbers.

Do you want to have them both running? Toggle?

You can try this package https://github.com/coldnew/linum-relative

And then I think you can toggle it

M-x linum-relative-toggle
