Evil: How to add keybinding for changing buffers?

Question

With Evil mode, :bn shows the next buffer, and :bp shows the previous buffer. I wish to define a custom keybinding where <Space>n shows the next buffer, and <Space>p shows the previous buffer.

In Vim, this can be accomplished using:

nnoremap <leader>n :bnext<cr>
nnoremap <leader>p :bprevious<cr>

where <leader> is Space.

How can I define these keybindings for Evil mode?

Answer 1

I have something like this in my config, inspired by spacemacs:

(use-package evil
  :init
  (use-package evil-leader
    :commands (evil-leader-mode global-evil-leader-mode)
    :demand
    :config
    (evil-leader/set-leader "SPC")
    (global-evil-leader-mode t))
  :config
  (evil-mode 1))

(evil-leader/set-key
  "bn" 'next-buffer
  "bp" 'previous-buffer)

this requires to type SPC b n or SPC b p, which I recommend becasue it makes more room for other bindings,

but you can remove the bs in the last two lines there, if you prefer the shorter binding.
