display relative line number in emacs.
linum-relative lets you display relative line numbers for current buffer.
If you have
emacs24 installed, simply type:
M-x package-install linum-relative
And add the following to your .emacs
Setup & Tips
The non-interactive function linum-on (which should already be built into recent GNU Emacs distributions), turns on side-bar line numbering:
and alternatively, by using command:
Relative line numbering should already be enabled by default (by installing this package), following linum-on or enabling linum-mode. One can also use the linum-relative-toggle interactive function to switch between relative and non-relative line numbering:
By default, linum-relative use linum-mode as backend, since linum-mode is based on emacs-lisp, you may have performance issue on large file.
Since linum-relative 0.6, if you also use emacs version 26.1 or above, you can setup
linum-relative-backend to make linum-relative-mode use
display-line-number-mode as backend, which is implement in C so the performance is really nice.
However some linum-relative's customize function may not work propely.
Here's how to use
display-line-number-mode as backend:
;; Use `display-line-number-mode` as linum-mode's backend for smooth performance (setq linum-relative-backend 'display-line-numbers-mode)
Return non nil when in an helm session.
Turn ON linum-relative.
Turn OFF linum-relative.
Toggle between linum-relative and linum.
