Evil-leader: Leader key working in special buffers like *Message*, *Backtrace*, etc

Question

The leader key works most buffers and in other special buffers like Help but not in others. Is there a setting for having evil-leader work in all buffers? This is an example of my evil-leader configuration

(use-package evil-leader
    :ensure t
    :config
    (global-evil-leader-mode t)
    (evil-leader/set-leader "<SPC>")
    (evil-leader/set-key
        "bd" 'kill-this-buffer
        "fd" 'init-file
        "ff" 'find-file
        "fs" 'save-buffer
        "k" 'switch-to-buffer
        "xh" 'mark-whole-buffer)

Answer 1

I suggest to use general.el since evil-leader is not update since 2014.

Here is a minimal example that works in *Message* and *Backtrace*

(use-package general
  :ensure t
  :after evil
  :config
  (general-create-definer tyrant-def
    :states '(normal insert motion emacs)
    :keymaps 'override
    :prefix "SPC"
    :non-normal-prefix "M-SPC")
  (tyrant-def "" nil)

  (general-def universal-argument-map
    "SPC u" 'universal-argument-more)

  (tyrant-def
    "bd" 'kill-this-buffer
    "fd" 'init-file
    "ff" 'find-file
    "fs" 'save-buffer
    "k" 'switch-to-buffer
    "xh" 'mark-whole-buffer))
