* Keybinding Managers
|
||
** Which-key
|
||
Which key is, I think, one of my favorite quality of life package.
|
||
When you begin a keybind, Emacs will show you all keybinds you can
|
||
follow the first one with in order to form a full keychord. Very
|
||
useful when you have a lot of keybinds and don’t remember exactly what
|
||
is what.
|
||
#+begin_src emacs-lisp
|
||
(use-package which-key
|
||
:straight (:build t)
|
||
:defer t
|
||
:init (which-key-mode)
|
||
:diminish which-key-mode
|
||
:config
|
||
(setq which-key-idle-delay 1))
|
||
#+end_src
|
||
|
||
** General
|
||
General is an awesome package for managing keybindings. Not only is it
|
||
oriented towards keychords by default (which I love), but it also
|
||
provides some integration with evil so that we can declare keybindings
|
||
for certain states only! This is a perfect replacement for ~define-key~,
|
||
~evil-define-key~, and any other function for defining keychords. And it
|
||
is also possible to declare a prefix for my keybindings! By default,
|
||
all keybinds will be prefixed with ~SPC~ and keybinds related to a
|
||
specific mode (often major modes) will be prefixed by a comma ~,~ (and
|
||
by ~C-SPC~ and ~M-m~ respectively when in ~insert-mode~ or ~emacs-mode~). You
|
||
can still feel some influence from my Spacemacs years here.
|
||
#+begin_src emacs-lisp
|
||
(use-package general
|
||
:straight (:build t)
|
||
:init
|
||
(general-auto-unbind-keys)
|
||
:config
|
||
(general-create-definer phundrak/undefine

|
||
:states '(normal))
|

|
||
:states '(normal insert visual emacs)
|
||
:keymaps 'override
|
||
:prefix "SPC"
|
||
:global-prefix "C-SPC")
|
||
(general-create-definer phundrak/major-leader-key
|
||
:states '(normal insert visual emacs)
|
||
:keymaps 'override
|
||
:prefix ","
|
||
:global-prefix "M-m"))
|
||
#+end_src
|
||
|
||
** Evil
|
||
Evil emulates most of vim’s keybinds, because let’s be honest here,
|
||
they are much more comfortable than Emacs’.
|
||
#+begin_src emacs-lisp
|
||
(use-package evil
|
||
:straight (:build t)
|
||
:after (general)
|
||
:init
|
||
(setq evil-want-integration t
|
||
evil-want-keybinding nil
|
||
evil-want-C-u-scroll t
|
||
evil-want-C-i-jump nil)
|
||
(require 'evil-vars)
|
||
:config
|
||
<<evil-undefine-keys>>
|
||
<<evil-bepo>>
|
||
(evil-mode 1)
|
||
(setq evil-want-fine-undo t) ; more granular undo with evil
|
||
(evil-set-initial-state 'messages-buffer-mode 'normal)
|
||
(evil-set-initial-state 'dashboard-mode 'normal))
|
||
#+end_src
|
||
|
||
I want to undefine some default keybinds of Evil because it does not
|
||
match my workflow. Namely, I use the space key and the comma as
|
||
leaders for my keybinds, and I’m way too used to Emacs’ ~C-t~, ~C-a~, ~C-e~,
|
||
and ~C-y~.
|
||
#+name: evil-undefine-keys
|
||
#+begin_src emacs-lisp :tangle no
|
||
(evil-global-set-key 'motion "t" 'evil-next-visual-line)
|
||
(evil-global-set-key 'motion "s" 'evil-previous-visual-line)
|
||
|
||
(general-define-key
|
||
:keymaps 'evil-motion-state-map
|
||
"SPC" nil
|
||
"," nil)
|
||
(general-define-key
|
||
:keymaps 'evil-insert-state-map
|
||
"C-t" nil)
|
||
(general-define-key
|
||
:keymaps 'evil-insert-state-map
|
||
"U" nil
|
||
"C-a" nil
|
||
"C-y" nil
|
||
"C-e" nil)
|
||
#+end_src
|
||
|
||
Something else that really bugs me is I use the bépo layout, which is
|
||
not at all like the qwerty layout. For instance, ~hjkl~ becomes ~ctsr~.
|
||
Thus, I need some bépo-specific changes.
|
||
#+name: evil-bepo
|
||
#+begin_src emacs-lisp :tangle no
|
||
(dolist (key '("c" "C" "t" "T" "s" "S" "r" "R" "h" "H" "j" "J" "k" "K" "l" "L"))
|
||
(general-define-key :states 'normal key nil))
|
||
|
||
(general-define-key
|
||
:states 'motion
|
||
"h" 'evil-replace
|
||
"H" 'evil-replace-state
|
||
"j" 'evil-find-char-to
|
||
"J" 'evil-find-char-to-backward
|
||
"k" 'evil-substitute
|
||
"K" 'evil-smart-doc-lookup
|
||
"l" 'evil-change
|
||
"L" 'evil-change-line
|
||
|
||
"c" 'evil-backward-char
|
||
"C" 'evil-window-top
|
||
"t" 'evil-next-visual-line
|
||
"T" 'evil-join
|
||
"s" 'evil-previous-visual-line
|
||
"S" 'evil-lookup
|
||
"r" 'evil-forward-char
|
||
"R" 'evil-window-bottom)
|
||
#+end_src
|
||
|
||
This package enables and integrates Evil into a lot of different
|
||
modes, such as org-mode, dired, mu4e, etc. Again, I need some
|
||
additional code compared to most people due to the bépo layout.
|
||
#+begin_src emacs-lisp
|
||
(use-package evil-collection
|
||
:after evil
|
||
:straight (:build t)
|
||
:config
|
||
;; bépo conversion
|
||
(defun my/bépo-rotate-evil-collection (_mode mode-keymaps &rest _rest)
|
||
(evil-collection-translate-key 'normal mode-keymaps
|
||
;; bépo ctsr is qwerty hjkl
|
||
"c" "h"
|
||
"t" "j"
|
||
"s" "k"
|
||
"r" "l"
|
||
;; add back ctsr
|
||
"h" "c"
|
||
"j" "t"
|
||
"k" "s"
|
||
"l" "r"))
|
||
(add-hook 'evil-collection-setup-hook #'my/bépo-rotate-evil-collection)
|
||
(evil-collection-init))
|
||
#+end_src
|
||
|
||
** Hydra
|
||
[[https://github.com/abo-abo/hydra][Hydra]] is a simple menu creator for keybindings.
|

#+begin_src emacs-lisp

(use-package hydra

:straight (:build t)
|

:defer t)
|

#+end_src
