#+TITLE : Ryan's Emacs config
#+AUTHOR : Ryan Kes
#+DESCRIPTION : There are many Emacs configs, this one is mine
* About
My personal Emacs config.
** init.el
To load this config add the following to ~init.el~
#+begin_example
(org-babel-load-file
(expand-file-name
"config.org"
user-emacs-directory))
#+end_example
* Package Management
** Archives
#+begin_src emacs-lisp
(setq package-archives '(("melpa" . "https://melpa.org/packages/ ")
("org" . "https://orgmode.org/elpa/ ")
("elpa" . "https://elpa.gnu.org/packages/ ")))
(package-initialize)
(unless package-archive-contents
(package-refresh-contents))
#+end_src
** Use-Package
The ~use-package~ macro allows you to isolate package configuration in your ~.emacs~ file in a way that is both performance-oriented and, well, tidy.
#+begin_src emacs-lisp
(unless (package-installed-p 'use-package)
(package-install 'use-package))
(require 'use-package)
;; "ensure" packages by default
(setq use-package-always-ensure t)
#+end_src
** Ensure
The ~:ensure~ keyword causes the package(s) to be installed automatically if not already present on your system
#+begin_src emacs-lisp
(require 'use-package-ensure)
(setq use-package-always-ensure t)
#+end_src
* General Configuration
** User Interface
Start with minimal interface
#+begin_src emacs-lisp
(setq inhibit-startup-message t) ;; Disable startup message
(scroll-bar-mode -1) ; Disable visible scrollbar
(tool-bar-mode -1) ; Disable the toolbar
(tooltip-mode -1) ; Disable tooltips
(menu-bar-mode -1) ; Disable the menu bar
;; Set up the visible bell
(setq visible-bell t)
#+end_src
2021-05-04 18:40:43 +00:00
Enable line numbers and customize their format.
#+begin_src emacs-lisp
(column-number-mode)
(global-display-line-numbers-mode t)
#+end_src
2021-05-03 19:05:55 +00:00
** Theme
#+begin_src emacs-lisp
2021-05-04 18:40:43 +00:00
(use-package doom-themes)
(load-theme 'doom-molokai t)
2021-05-03 19:05:55 +00:00
#+end_src
** Font
#+begin_src emacs-lisp
(set-face-attribute 'default nil :font "JetBrainsMono Nerd Font")
#+end_src
** Mode Line
*** Doom Modeline
#+begin_src emacs-lisp
(use-package doom-modeline
:init (doom-modeline-mode 1)
:custom (doom-modeline-height 15))
#+end_src
* Keyboard Bindings
2021-05-04 18:40:43 +00:00
** Escape Cancels All
#+begin_src emacs-lisp
2021-05-03 19:05:55 +00:00
(global-set-key (kbd "<escape >") 'keyboard-escape-quit)
#+end_src
** Evil Mode
Evil Collection is also installed since it adds 'evil' bindings to parts of Emacs that the standard Evil package does not cover, such as: calenda, help-mode adn ibuffer.
#+begin_src emacs-lisp
(use-package evil
:init ;; tweak evil's configuration before loading it
(setq evil-want-integration t) ;; This is optional since it's already set to t by default.
(setq evil-want-keybinding nil)
(setq evil-vsplit-window-right t)
(setq evil-split-window-below t)
(evil-mode))
(use-package evil-collection
:after evil
:config
(setq evil-collection-mode-list '(dashboard dired ibuffer))
(evil-collection-init))
#+end_src
** General Keybindings
~general.el~ provides a more convenient way to bind keys in emacs for both evil and non-evil users. ~general-define-key~ allows defining multiple keys at once, implicitly wrapping key strings with (kbd ...), having named prefix key sequences (like the leader key in vim), and more.
#+begin_src emacs-lisp
(use-package general
:config
(general-evil-setup t))
#+end_src
2021-05-04 18:40:43 +00:00
** Keybinding Panel (which-key)
[[https://github.com/justbur/emacs-which-key ][which-key ]] shows an overview of what keybindings are available based on the prefix keys you entered.
#+begin_src emacs-lisp
(use-package which-key
:init (which-key-mode)
:config(setq which-key-idle-delay 0.3))
#+end_src
2021-05-03 19:05:55 +00:00
* Ivy
2021-05-04 18:40:43 +00:00
** General
2021-05-03 19:05:55 +00:00
#+begin_src emacs-lisp
(use-package ivy
:diminish
:bind (("C-s" . swiper)
:map ivy-minibuffer-map
("TAB" . ivy-alt-done)
("C-l" . ivy-alt-done)
("C-j" . ivy-next-line)
("C-k" . ivy-previous-line)
:map ivy-switch-buffer-map
("C-k" . ivy-previous-line)
("C-l" . ivy-done)
("C-d" . ivy-switch-buffer-kill)
:map ivy-reverse-i-search-map
("C-k" . ivy-previous-line)
("C-d" . ivy-reverse-i-search-kill))
:init
(ivy-mode 1)) ;; Load keybindings
#+end_src
2021-05-04 18:40:43 +00:00
** Ivy-rich
[[https://github.com/Yevgnen/ivy-rich ][ivy-rich ]] comes with rich transformers for commands from ~ivy~ and ~counsel~ .
#+begin_src emacs-lisp
(use-package ivy-rich
:after counsel
:init
(ivy-rich-mode 1))
#+end_src
** Counsel
~ivy-mode~ ensures that any Emacs command using ~completing-read-function~ uses ivy for completion.
Counsel takes this further, providing versions of common Emacs commands that are customised to make the best use of Ivy. For example, ~counsel-find-file~ has some additional keybindings. Pressing ~DEL~ will move you to the parent directory.
#+begin_src emacs-lisp
(use-package counsel
:demand t
:bind (("M-x" . counsel-M-x)
("C-x b" . counsel-ibuffer)
("C-x C-f" . counsel-find-file)
;; ("C-M-j" . counsel-switch-buffer)
("C-M-l" . counsel-imenu)
:map minibuffer-local-map
("C-r" . 'counsel-minibuffer-history))
:custom
(counsel-linux-app-format-function #'counsel-linux-app-format-function-name-only)
:config
(setq ivy-initial-inputs-alist nil)) ;; Don't start searches with ^
#+end_src
* Development
** Languages
*** Emacs Lisp
**** Helpful
[[https://github.com/Wilfred/helpful ][Helpful ]] is an alternative to the built-in Emacs help that provides much more contextual information.
#+begin_src emacs-lisp
(use-package helpful
:custom
(counsel-describe-function-function #'helpful-callable)
(counsel-describe-variable-function #'helpful-variable)
:bind
([remap describe-function] . helpful-function)
([remap describe-symbol] . helpful-symbol)
([remap describe-variable] . helpful-variable)
([remap describe-command] . helpful-command)
([remap describe-key] . helpful-key))
#+end_src
** Productivity
*** Rainbow Delimiters
#+begin_src emacs-lisp
(use-package rainbow-delimiters
:hook (prog-mode . rainbow-delimiters-mode))
#+end_src
