I just started using emacs with Evil mode. In my .vimrc file I had the following:
nnoremap ; :
nnoremap : ;
What would I put in my .emacs file to achieve the same thing in emacs evil mode?
This'll do it:
(define-key evil-motion-state-map ";" #'evil-ex)
(define-key evil-motion-state-map ":" #'evil-repeat-find-char)
Place it anywhere after you've loaded evil-mode.
EDIT: You can also use evil-define-key / evil-define-key*:
(evil-define-key* 'motion 'global
";" #'evil-ex
":" #'evil-repeat-find-char)
The difference between evil-define-key and evil-define-key* is the latter will defer the keybinds under the motion keymap is available (if it isn't already).
You can find documentation on the function with M-x describe-function RET evil-define-key* or C-hf describe-function RET.
