PUT THIS IN YOUR INIT.EL I don't want to use init.el to config Emacs. I want to use an org file to config Emacs because I like literate configs with lots of comments. The following code block should be your init.el. This tells init.el to use the source code blocks from this file (config.org). #+begin_example (org-babel-load-file (expand-file-name "config.org" user-emacs-directory)) #+end_example * ABOUT THIS CONFIG This is my personal Emacs config. I patterned my config to mimic Doom Emacs, which is a distribution of Emacs that uses the "evil" keybindings (Vim keybindings) and includes a number of nice extensions and a bit of configuration out of the box. I am maintaining this config not just for myself, but also for those that want to explore some of what is possible with Emacs. I will add a lot of examples of plugins and settings, some of them I may not even use personally. I do this because many people following me on YouTube and Odysee look at my configs as "documentation". * A FEW PROGRAMS TO LOAD FIRST The order in which the various Emacs modules load is very important. So the very first code block is going to contain essential modules that many other modules will depend on later in this config. ** Setup Package.el To Work With MELPA #+begin_src emacs-lisp (require 'package) (add-to-list 'package-archives '("melpa" . "https://melpa.org/packages/")) (package-refresh-contents) (package-initialize) #+end_src ** Use-Package Install use-package and enable ':ensure t' globally. The ':ensure' keyword causes the package(s) within use-package statements to be installed automatically if not already present on your system. To avoid having to add ':ensure t' to every use-package statement in this config, I set 'use-package-always-ensure'. #+begin_src emacs-lisp (unless (package-installed-p 'use-package) (package-install 'use-package)) (setq use-package-always-ensure t) #+end_src ** Evil Mode Evil is an extensible 'vi' layer for Emacs. It emulates the main features of Vim, and provides facilities for writing custom extensions. 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)) (use-package evil-tutor) #+end_src ** General Keybindings General.el allows us to set keybindings. As a longtime Doom Emacs user, I have grown accustomed to using SPC as the prefix key. General makes setting keybindings (especially with SPC) much easier. All of the keybindings we set later in the config depend on general being loaded. #+begin_src emacs-lisp (use-package general :config (general-evil-setup t)) #+end_src * ALL THE ICONS This is an icon set that can be used with dashboard, dired, ibuffer and other Emacs programs. #+begin_src emacs-lisp (use-package all-the-icons) #+end_src * BUFFERS AND BOOKMARKS #+begin_src emacs-lisp (nvmap :prefix "SPC" "b b" '(ibuffer :which-key "Ibuffer") "b c" '(clone-indirect-buffer-other-window :which-key "Clone indirect buffer other window") "b k" '(kill-current-buffer :which-key "Kill current buffer") "b n" '(next-buffer :which-key "Next buffer") "b p" '(previous-buffer :which-key "Previous buffer") "b B" '(ibuffer-list-buffers :which-key "Ibuffer list buffers") "b K" '(kill-buffer :which-key "Kill buffer")) #+end_src * DASHBOARD Emacs Dashboard is an extensible startup screen showing you recent files, bookmarks, agenda items and an Emacs banner. ** Configuring Dashboard #+begin_src emacs-lisp (use-package dashboard :init ;; tweak dashboard config before loading it (setq dashboard-set-heading-icons t) (setq dashboard-set-file-icons t) (setq dashboard-banner-logo-title "Emacs Is More Than A Text Editor!") ;;(setq dashboard-startup-banner 'logo) ;; use standard emacs logo as banner (setq dashboard-startup-banner "~/.emacs.d/emacs-dash.png") ;; use custom image as banner (setq dashboard-center-content nil) ;; set to 't' for centered content (setq dashboard-items '((recents . 5) (agenda . 5 ) (bookmarks . 3) (projects . 3) (registers . 3))) :config (dashboard-setup-startup-hook) (dashboard-modify-heading-icons '((recents .

The following line removes the annoying '^' in things like counsel-M-x and other ivy/counsel prompts.

NeoTree provides following themes: classic, ascii, arrow, icons, and nerd. Theme can be configed by setting "two" themes for neo-theme: one for the GUI and one for the terminal.
