Re: Display window line numbers

[João Paulo Labegalini de Carvalho]

Juri,

You could set `display-line-numbers' to 'absolute and run code below every time the window is scrolled up/down (e.g. with a hook):

(save-excursion

  (move-to-window-line 0)

  (setq display-line-numbers-offset

           (* -1

              (line-number-at-pos))))

Notice that if `display-line-numbers' is 'absolute and narrowing is enabled, you already get your desired behaviour.

to display line numbers relative to the window-start?
IMHO, one of the most reasonable excuses to sacrifice the screen space
for line numbers is to display only these short numbers that could be
used to jump to a line visible on the screen.  For that the quickest
key sequence is e.g. 'M-5 M-r'.

Then all possibilities will be covered by these options of
‘display-line-numbers’:

- absolute line numbers can be used by 'M-g M-g' (goto-line);
- relative line numbers - by 'C-u N C-n' and 'C-u N C-p';
- window line numbers - by 'M-r'.
