;; Keys
;; Make the =ESC= key quit (most) prompts, instead of the default =C-g=.
(global-set-key (kbd "<escape>") 'keyboard-escape-quit)
;; Download [[https://github.com/justbur/emacs-which-key][which-key]], a package that displays the current incomplete keybinding input in a mini-buffer, showing available completion options.
(use-package which-key :diminish which-key-mode :custom (which-key-idle-delay dotfiles/idle) :config (which-key-mode))
;; Turn Emacs into Vim with [[https://evil.readthedocs.io/en/latest/index.html][evil-mode]], the extensible VI layer for Emacs.
(use-package evil :custom (evil-want-integration t) ;; Required for `evil-collection'. (evil-want-keybinding nil) ;; Same as above :config (evil-mode 1))
;; Unfortunately the default keybindings are *lacking*, but there is a community curated package [[https://github.com/emacs-evil/evil-collection][evil-collection]], which does a much better job implementing keybindings you would expect to find.
(use-package evil-collection :after evil :config (evil-collection-init))
;; Surround text with functions, quotations, and any other symbols using the [[https://github.com/emacs-evil/evil-surround][evil-surround]] package.
(use-package evil-surround :after evil :config (global-evil-surround-mode 1))
;; Toggle block comments using [[https://github.com/redguardtoo/evil-nerd-commenter][evil-nerd-commentor]] and =M-;=.
(use-package evil-nerd-commenter :after evil :bind ("M-;" . evilnc-comment-or-uncomment-lines))
;; Implement the *leader* key using [[https://github.com/noctuid/general.el][general.el]], letting us easily configure prefixed keybindings in a much cleaner manner than the default methods.
(use-package general :after evil :config (general-create-definer dotfiles/leader :states '(normal motion) :keymaps 'override :prefix dotfiles/leader-key :global-prefix dotfiles/leader-key-global))
;; Use [[https://github.com/abo-abo/hydra][hydra]] for transient keybindings sharing a common prefix.
(use-package hydra :defer t)
;; Help
;; Use the built-in ~describe-*~ functionality of Emacs to quickly access documentation for packages, variables, and functions. Run helper functions with =SPC h=.
;; + Packages =p=;; + Variables =v=;; + Functions =f=
(dotfiles/leader "h" '(:ignore t :which-key "Help") "hp" '(describe-package :which-key "Package") "hv" '(describe-variable :which-key "Variable") "hf" '(describe-function :which-key "Function"))
;; Files
;; For file navigation I use =dired=, included with Emacs by default. Dired feels more modern with prioritized icon fonts using [[https://github.com/domtronn/all-the-icons.el][all-the-icons]]. This makes navigation and visually parsing directories much faster, given that file types are quickly identified by their corresponding icons.
(use-package all-the-icons)
;; Integration with =dired= comes from the [[https://github.com/jtbm37/all-the-icons-dired][all-the-icons-dired]] package.
(use-package all-the-icons-dired :hook (dired-mode . all-the-icons-dired-mode))
;; When opening =dired=, I don't want to have to press =RET= twice to navigate to the current directory. Avoid this with ~dired-jump~, included in the =dired-x= package shipped with =dired= and Emacs.
(require 'dired-x)
;; By default =dired= will create a new buffer everytime you press =RET= over a directory. This leads to unwanted =dired= buffers needing closure. Avoid this behaviour with [[https://github.com/crocket/dired-single][dired-single]], reusing the same dired buffer.
;; + Move up a directory with =h=;; + Open a single buffer with =l=
(use-package dired-single :config (evil-collection-define-key 'normal 'dired-mode-map "h" 'dired-single-up-directory "l" 'dired-single-buffer))
;; Open a dired buffer with =SPC d=.
(dotfiles/leader "d" '(dired-jump :which-key "Dired"))
;; Shell
;; While not a traditional terminal emulator, =eshell= provides me with all of the functionality I expect and require from one. Some users may be wanting more, I would recommend they look into =vterm= included in the destkop module. Configure the infamous lambda prompt using [[https://github.com/zwild/eshell-prompt-extras][eshell-prompt-extras]] package.
(use-package eshell-prompt-extras :custom (eshell-highlight-prompt nil) (eshell-prefer-lisp-functions nil) (eshell-prompt-function 'epe-theme-lambda))
;; Make ~pfetch~ output as a visual command.
