DRK's Doom Emacs Config

TABLE OF CONTENTS   toc

ABOUT THIS CONFIG

This is my personal Doom Emacs config. Doom Emacs 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 look at my configs as "documentation". This config is a fork of DistroTube's config.

BEACON

Never lose your cursor. When you scroll, your cursor will shine! This is a global minor-mode. Turn it on everywhere with:

(beacon-mode 1)

BOOKMARKS AND BUFFERS

Doom Emacs uses 'SPC b' for keybindings related to bookmarks and buffers.

Bookmarks

Bookmarks are somewhat like registers in that they record positions you can jump to. Unlike registers, they have long names, and they persist automatically from one Emacs session to the next. The prototypical use of bookmarks is to record where you were reading in various files.

(map! :leader
      (:prefix ("b". "buffer")
       :desc "List bookmarks" "L" #'list-bookmarks
       :desc "Save current bookmarks to bookmark file" "w" #'bookmark-save))

Buffers

Regarding buffers, the text you are editing in Emacs resides in an object called a buffer. Each time you visit a file, a buffer is used to hold the file’s text. Each time you invoke Dired, a buffer is used to hold the directory listing. Ibuffer is a program that lists all of your Emacs buffers, allowing you to navigate between them and filter them.

COMMAND DESCRIPTION KEYBINDING
ibuffer Launch ibuffer SPC b i
kill-buffer Kill current buffer SPC b k
next-buffer Goto next buffer SPC b n
previous-buffer Goto previous buffer SPC b p
save-buffer Save current buffer SPC b s

Global Auto Revert

A buffer can get out of sync with respect to its visited file on disk if that file is changed by another program. To keep it up to date, you can enable Auto Revert mode by typing M-x auto-revert-mode, or you can set it to be turned on globally with 'global-auto-revert-mode'. I have also turned on Global Auto Revert on non-file buffers, which is especially useful for 'dired' buffers.

CALENDAR

Let's make a 12-month calendar available so we can have a calendar app that, when we click on time/date in xmobar, we get a nice 12-month calendar to view.

CENTAUR-TABS

To use tabs in Doom Emacs, be sure to uncomment "tabs" in Doom's init.el. Displays tabs at the top of the window similar to tabbed web browsers such as Firefox. I don't actually use tabs in Emacs. I placed this in my config to help others who may want tabs. In the default configuration of Doom Emacs, 'SPC t' is used for "toggle" keybindings, so I choose 'SPC t c' to toggle centaur-tabs. The "g" prefix for keybindings is used for a bunch of evil keybindings in Doom, but "g" plus the arrow keys were not used, so I thought I would bind those for tab navigation. But I did leave the default "g t" and "g T" intact if you prefer to use those for centaur-tabs-forward/backward.

COMMAND DESCRIPTION KEYBINDING
centaur-tabs-mode Toggle tabs globally SPC t c
centaur-tabs-local-mode Toggle tabs local display SPC t C
centaur-tabs-forward Next tab g <right> or g t
centaur-tabs-backward Previous tab g <left> or g T

                                               (kbd "g <up>")    'centaur-tabs-backward-group)

CLIPPY

Gives us a popup box with "Clippy, the paper clip". You can make him say various things by calling 'clippy-say' function. But the more useful functions of clippy are the two describe functions provided: 'clippy-describe-function' and 'clippy-describe-variable'. Hit the appropriate keybinding while the point is over a function/variable to call it. A popup with helpful clippy will appear, telling you about the function/variable (using describe-function and describe-variable respectively).

COMMAND DESCRIPTION KEYBINDING
clippy-describe-function Clippy describes function under point SPC c h f
clippy-describe-variable Clippy describes variable under point SPC c h v 
(map! :leader
      (:prefix ("c h" . "Help info from Clippy")
       :desc "Clippy describes function under point" "f" #'clippy-describe-function
       :desc "Clippy describes variable under point" "v" #'clippy-describe-variable))

DASHBOARD

Emacs Dashboard is an extensible startup screen showing you recent files, bookmarks, agenda items and an Emacs banner.

Configuring Dashboard 

(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 "\nKEYBINDINGS:\
\nFind file               (SPC .)     \
Open buffer list    (SPC b i)\
\nFind recent files       (SPC f r)   \
Open the eshell     (SPC e s)\
\nOpen dired file manager (SPC d d)   \
List of keybindings (SPC h b b)")
  ;;(setq dashboard-startup-banner 'logo) ;; use standard emacs logo as banner
  (setq initial-buffer-choice (lambda () (get-buffer "*dashboard*")))
  (setq dashboard-startup-banner "~/.config/doom/emacs-dash.txt")  ;; use custom image as banner
  (setq dashboard-center-content nil) ;; set to 't' for centered content
  (setq dashboard-items '((recents . 5)
                          (agenda . 5 )
                          (bookmarks . 5)
                          (projects . 5)

  (dashboard-modify-heading-icons '((recents . "file-text")
                                    (bookmarks . "book"))))

Dashboard in Emacsclient

This setting ensures that emacsclient always opens on dashboard rather than scratch.

(setq doom-fallback-buffer "*dashboard*")

DIRED

Dired is the file manager within Emacs. Below, I setup keybindings for image previews (peep-dired). Doom Emacs does not use 'SPC d' for any of its keybindings, so I've chosen the format of 'SPC d' plus 'key'.

Making deleted files go to trash can 

(setq delete-by-moving-to-trash t

DOOM THEME

Setting the theme to doom-one. To try out new themes, I set a keybinding for counsel-load-theme with 'SPC h t'.

(setq doom-theme 'doom-gruvbox)
(map! :leader
      :desc "Load new theme" "h t" #'counsel-load-theme)

EMMS

One of the media players available for Emacs is emms, which stands for Emacs Multimedia System. By default, Doom Emacs does not use 'SPC a',' so the format I use for these bindings is 'SPC a' plus 'key'.

COMMAND DESCRIPTION KEYBINDING

EMOJIS

Emojify is an Emacs extension to display emojis. It can display github style emojis like 😄 or plain ascii ones like :).

(use-package emojify
  :hook (after-init . global-emojify-mode))

ERC

ERC is a built-in Emacs IRC client.

COMMAND DESCRIPTION KEYBINDING

EVALUATE ELISP EXPRESSIONS

Changing some keybindings from their defaults to better fit with Doom Emacs, and to avoid conflicts with my window managers which sometimes use the control key in their keybindings. By default, Doom Emacs does not use 'SPC e' for anything, so I choose to use the format 'SPC e' plus 'key' for these (I also use 'SPC e' for 'eww' keybindings).

COMMAND DESCRIPTION KEYBINDING
eval-buffer Evaluate elisp in buffer SPC e b
eval-defun Evaluate the defun containing or after point SPC e d
eval-expression Evaluate an elisp expression SPC e e
eval-last-sexp Evaluate elisp expression before point SPC e l
eval-region Evaluate elisp in region SPC e r 
(map! :leader
      (:prefix ("e". "evaluate/EWW")
       :desc "Evaluate elisp in buffer" "b" #'eval-buffer
       :desc "Evaluate defun" "d" #'eval-defun

       :desc "Evaluate last sexpression" "l" #'eval-last-sexp
       :desc "Evaluate elisp in region" "r" #'eval-region))

EWW

EWW is the Emacs Web Wowser, the builtin browser in Emacs. Below I set urls to open in a specific browser (eww) with browse-url-browser-function. By default, Doom Emacs does not use 'SPC e' for anything, so I choose to use the format 'SPC e' plus 'key' for these (I also use 'SPC e' for 'eval' keybindings). I chose to use 'SPC s w' for eww-search-words because Doom Emacs uses 'SPC s' for 'search' commands.

(setq browse-url-browser-function 'eww-browse-url)
(map! :leader
      :desc "Search web for text between BEG/END"
      "s w" #'eww-search-words
      (:prefix ("e" . "evaluate/EWW")
       :desc "Eww web browser" "w" #'eww
       :desc "Eww reload page" "R" #'eww-reload))

FONTS

Settings related to fonts within Doom Emacs:

  • 'doom-font' – standard monospace font that is used for most things in Emacs.
  • 'doom-variable-pitch-font' – variable font which is useful in some Emacs plugins.
  • 'doom-big-font' – used in doom-big-font-mode; useful for presentations.
  • 'font-lock-comment-face' – for comments.
  • 'font-lock-keyword-face' – for keywords with special significanclike 'setq' in elisp.
(setq doom-font (font-spec :family "mononoki Nerd Font" :size 15)
      doom-variable-pitch-font (font-spec :family "mononoki Nerd Font" :size 15)
      doom-big-font (font-spec :family "mononoki Nerd Font" :size 20))
(after! doom-themes
  (setq doom-themes-enable-bold t
        doom-themes-enable-italic t))
(custom-set-faces!
  '(font-lock-comment-face :slant italic)
  '(font-lock-keyword-face :slant italic))

INSERT DATE

Some custom functions to insert the date. The function 'insert-todays-date' can be used one of three different ways: (1) just the keybinding without the universal argument prefix, (2) with one universal argument prefix, or (3) with two universal argument prefixes. The universal argument prefix is 'SPC-u' in Doom Emacs (C-u in standard GNU Emacs). The function 'insert-any-date' only outputs to one format, which is the same format as 'insert-todays-date' without a prefix.

COMMAND EXAMPLE OUTPUT KEYBINDING

IVY

Ivy is a generic completion mechanism for Emacs.

IVY-POSFRAME

Ivy-posframe is an ivy extension, which lets ivy use posframe to show its candidate menu. Some of the settings below involve:

  • ivy-posframe-display-functions-alist – sets the display position for specific programs
  • ivy-posframe-height-alist – sets the height of the list displayed for specific programs

Available functions (positions) for 'ivy-posframe-display-functions-alist'

  • ivy-posframe-display-at-frame-center
  • ivy-posframe-display-at-window-center
  • ivy-posframe-display-at-frame-bottom-left
  • ivy-posframe-display-at-window-bottom-left
  • ivy-posframe-display-at-frame-bottom-window-center
  • ivy-posframe-display-at-point
  • ivy-posframe-display-at-frame-top-center

NOTE: If the setting for 'ivy-posframe-display' is set to 'nil' (false), anything that is set to 'ivy-display-function-fallback' will just default to their normal position in Doom Emacs (usually a bottom split). However, if this is set to 't' (true), then the fallback position will be centered in the window.

(setq ivy-posframe-display-functions-alist
      '((swiper                     . ivy-posframe-display-at-point)
        (complete-symbol            . ivy-posframe-display-at-point)
        (counsel-M-x                . ivy-display-function-fallback)
        (counsel-esh-history        . ivy-posframe-display-at-window-center)

        (dmenu                      . ivy-posframe-display-at-frame-top-center)
        (nil                        . ivy-posframe-display))
      ivy-posframe-height-alist
      '((swiper . 20)
        (dmenu . 20)
        (t . 10)))
(ivy-posframe-mode 1) ; 1 enables posframe-mode, 0 disables it.

IVY KEYBINDINGS

By default, Doom Emacs does not use 'SPC v', so the format I use for these bindings is 'SPC v' plus 'key'.

(map! :leader
      (:prefix ("v" . "Ivy")
       :desc "Ivy push view" "v p" #'ivy-push-view
       :desc "Ivy switch view" "v s" #'ivy-switch-view))

LINE SETTINGS

I set comment-line to 'SPC TAB TAB' which is a rather comfortable keybinding for me on my ZSA Moonlander keyboard. The standard Emacs keybinding for comment-line is 'C-x C-;'. The other keybindings are for commands that toggle on/off various line-related settings. Doom Emacs uses 'SPC t' for "toggle" commands, so I choose 'SPC t' plus 'key' for those bindings.

COMMAND DESCRIPTION KEYBINDING
comment-line Comment or uncomment lines SPC TAB TAB
hl-line-mode Toggle line highlighting in current frame SPC t h
global-hl-line-mode Toggle line highlighting globally SPC t H
doom/toggle-line-numbers Toggle line numbers SPC t l
toggle-truncate-lines Toggle truncate lines SPC t t 
(setq display-line-numbers-type t)
(map! :leader
      :desc "Comment or uncomment lines" "TAB TAB" #'comment-line
      (:prefix ("t" . "toggle")
       :desc "Toggle line numbers" "l" #'doom/toggle-line-numbers
       :desc "Toggle line highlight in frame" "h" #'hl-line-mode
       :desc "Toggle line highlight globally" "H" #'global-hl-line-mode
       :desc "Toggle truncate lines" "t" #'toggle-truncate-lines))

MARKDOWN 

(custom-set-faces
 '(markdown-header-face ((t (:inherit font-lock-function-name-face :weight bold :family "variable-pitch"))))
 '(markdown-header-face-1 ((t (:inherit markdown-header-face :height 1.7))))
 '(markdown-header-face-2 ((t (:inherit markdown-header-face :height 1.6))))
 '(markdown-header-face-3 ((t (:inherit markdown-header-face :height 1.5))))
 '(markdown-header-face-4 ((t (:inherit markdown-header-face :height 1.4))))
 '(markdown-header-face-5 ((t (:inherit markdown-header-face :height 1.3))))
 '(markdown-header-face-6 ((t (:inherit markdown-header-face :height 1.2)))))

MINIMAP

A minimap sidebar displaying a smaller version of the current buffer on either the left or right side. It highlights the currently shown region and updates its position automatically. Be aware that this minimap program does not work in Org documents. This is not unusual though because I have tried several minimap programs and none of them can handle Org.

COMMAND DESCRIPTION KEYBINDING
minimap-mode Toggle minimap-mode SPC t m 
(setq minimap-window-location 'right)
(map! :leader
      (:prefix ("t" . "toggle")
       :desc "Toggle minimap-mode" "m" #'minimap-mode))

MODELINE

The modeline is the bottom status bar that appears in Emacs windows. For more information on what is available to configure in the Doom modeline, check out: https://github.com/seagle0128/doom-modeline

(set-face-attribute 'mode-line nil :font "mononoki Nerd Font-13")
(setq doom-modeline-height 30     ;; sets modeline height
      doom-modeline-bar-width 5   ;; sets right bar width
      doom-modeline-persp-name t  ;; adds perspective name to modeline
      doom-modeline-persp-icon t) ;; adds folder icon next to persp name

MOUSE SUPPORT

Adding mouse support in the terminal version of Emacs.

(xterm-mouse-mode 1)

NEOTREE

Neotree is a file tree viewer. When you open neotree, it jumps to the current file thanks to neo-smart-open. The neo-window-fixed-size setting makes the neotree width be adjustable. Doom Emacs had no keybindings set for neotree. Since Doom Emacs uses 'SPC t' for 'toggle' keybindings, I used 'SPC t n' for toggle-neotree.

COMMAND DESCRIPTION KEYBINDING
neotree-toggle Toggle neotree SPC t n
neotree- dir Open directory in neotree SPC d n 
(after! neotree
  (setq neo-smart-open t
        neo-window-fixed-size nil))
(after! doom-themes
  (setq doom-neotree-enable-variable-pitch t))
(map! :leader
      :desc "Toggle neotree file viewer" "t n" #'neotree-toggle
      :desc "Open directory in neotree" "d n" #'neotree-dir)

OPEN SPECIFIC FILES

Keybindings to open files that I work with all the time using the find-file command, which is the interactive file search that opens with 'C-x C-f' in GNU Emacs or 'SPC f f' in Doom Emacs. These keybindings use find-file non-interactively since we specify exactly what file to open. The format I use for these bindings is 'SPC =' plus 'key' since Doom Emacs does not use 'SPC ='.

PATH TO FILE DESCRIPTION KEYBINDING
~/Org/agenda.org Edit agenda file SPC = a

~/.config/doom/packages.el" Edit doom packages.el SPC = p

       :desc "Edit eshell profile" "p" #'(lambda () (interactive) (find-file "~/.config/doom/eshell/profile"))))

ORG MODE

I wrapped most of this block in (after! org). Without this, my settings might be evaluated too early, which will result in my settings being overwritten by Doom's defaults. I have also enabled org-journal, org-superstar and org-roam by adding (+journal +pretty +roam2) to the org section of my Doom Emacs init.el.

NOTE: I have the location of my Org directory and Roam directory in $HOME/nc/ which is a Nextcloud folder that allows me to instantly sync all of my Org work between my home computer and my office computer.

Org-export

We need ox-man for "Org eXporting" to manpage format and ox-gemini for exporting to gemtext (for the gemini protocol). NOTE: I also enable ox-publish for converting an Org site into an HTML site, but that is done in init.el (org +publish).

(use-package ox-man)

Org-publish 

(setq org-publish-use-timestamps-flag nil)
(setq org-export-with-broken-links t)

Org-auto-tangle

org-auto-tangle allows you to add the option #+auto_tangle: t in your Org file so that it automatically tangles when you save the document.

Perspective provides multiple named workspaces (or "perspectives") in Emacs, similar to having multiple desktops in window managers like Awesome and XMonad. Each perspective has its own buffer list and its own window layout, making it easy to work on many separate projects without getting lost in all the buffers. Switching to a perspective activates its window configuration, and when in a perspective, only its buffers are available (by default). Doom Emacs uses 'SPC some_key' for binding some of the perspective commands, so I used this binging format for the perspective bindings that I created..

COMMAND DESCRIPTION KEYBINDING
persp-switch Switch to perspective NAME SPC DEL
persp-switch-to-buffer Switch to buffer in perspective SPC ,
persp-next Switch to next perspective SPC ]
persp-prev Switch to previous perspective SPC [
persp-add-buffer Add a buffer to current perspective SPC +
persp-remove-by-name Remove perspective by name SPC -
+workspace/switch-to-{0-9} Switch to workspace n SPC 0-9 
(map! :leader
      :desc "Switch to perspective NAME" "DEL" #'persp-switch
      :desc "Switch to buffer in perspective" "," #'persp-switch-to-buffer
      :desc "Switch to next perspective" "]" #'persp-next
      :desc "Switch to previous perspective" "[" #'persp-prev
      :desc "Add a buffer current perspective" "+" #'persp-add-buffer
      :desc "Remove perspective by name" "-" #'persp-remove-by-name)

RAINBOW MODE

Rainbox mode displays the actual color for any hex value color. It's such a nice feature that I wanted it turned on all the time, regardless of what mode I am in. The following creates a global minor mode for rainbow-mode and enables it.

(define-globalized-minor-mode global-rainbow-mode rainbow-mode
  (lambda () (rainbow-mode 1)))
(global-rainbow-mode 1 )

REGISTERS

Emacs registers are compartments where you can save text, rectangles and positions for later use. Once you save text or a rectangle in a register, you can copy it into the buffer once or many times; once you save a position in a register, you can jump back to that position once or many times. The default GNU Emacs keybindings for these commands (with the exception of counsel-register) involves 'C-x r' followed by one or more other keys. I wanted to make this a little more user friendly, and since I am using Doom Emacs, I choose to replace the 'C-x r' part of the key chords with 'SPC r'.

COMMAND DESCRIPTION KEYBINDING
copy-to-register Copy to register SPC r c
frameset-to-register Frameset to register SPC r f
insert-register Insert contents of register SPC r i
jump-to-register Jump to register SPC r j
list-registers List registers SPC r l
number-to-register Number to register SPC r n
counsel-register Interactively choose a register SPC r r
view-register View a register SPC r v
window-configuration-to-register Window configuration to register SPC r w
increment-register Increment register SPC r +
point-to-register Point to register SPC r SPC 
(map! :leader
      (:prefix ("r" . "registers")
       :desc "Copy to register" "c" #'copy-to-register
       :desc "Frameset to register" "f" #'frameset-to-register
       :desc "Insert contents of register" "i" #'insert-register
       :desc "Jump to register" "j" #'jump-to-register
       :desc "List registers" "l" #'list-registers

       :desc "Window configuration to register" "w" #'window-configuration-to-register
       :desc "Increment register" "+" #'increment-register
       :desc "Point to register" "SPC" #'point-to-register))

SHELLS

Settings for the various shells and terminal emulators within Emacs.

  • 'shell-file-name' – sets the shell to be used in M-x shell, M-x term, M-x ansi-term and M-x vterm.
  • 'eshell-aliases-file' – sets an aliases file for the eshell.
(setq shell-file-name "/bin/bash"
      vterm-max-scrollback 5000)
(setq eshell-rc-script "~/.config/doom/eshell/profile"
      eshell-aliases-file "~/.config/doom/eshell/aliases"
      eshell-history-size 5000
      eshell-buffer-maximum-lines 5000
      eshell-hist-ignoredups t
      eshell-scroll-to-bottom-on-input t
      eshell-destroy-buffer-when-process-dies t
      eshell-visual-commands'("bash" "fish" "htop" "ssh" "top" "zsh"))
(map! :leader
      :desc "Eshell" "e s" #'eshell
      :desc "Eshell popup toggle" "e t" #'+eshell/toggle
      :desc "Counsel eshell history" "e h" #'counsel-esh-history
      :desc "Vterm popup toggle" "v t" #'+vterm/toggle)

SPLITS

I set splits to default to opening on the right using 'prefer-horizontal-split'. I set a keybinding for 'clone-indirect-buffer-other-window' for when I want to have the same document in two splits. The text of the indirect buffer is always identical to the text of its base buffer; changes made by editing either one are visible immediately in the other. But in all other respects, the indirect buffer and its base buffer are completely separate. For example, I can fold one split but other will be unfolded.

(defun prefer-horizontal-split ()
  (set-variable 'split-height-threshold nil t)
  (set-variable 'split-width-threshold 40 t)) ; make this as low as needed
(add-hook 'markdown-mode-hook 'prefer-horizontal-split)
(map! :leader
      :desc "Clone indirect buffer other window" "b c" #'clone-indirect-buffer-other-window)

WINNER MODE

Winner mode has been included with GNU Emacs since version 20. This is a global minor mode and, when activated, it allows you to “undo” (and “redo”) changes in the window configuration with the key commands 'SCP w <left>' and 'SPC w <right>'.

(map! :leader
      (:prefix ("w" . "window")
       :desc "Winner redo" "<right>" #'winner-redo
       :desc "Winner undo" "<left>" #'winner-undo))

ZAP TO CHAR

Emacs provides a 'zap-to-char' command that kills from the current point to a character. It is bound to 'M-z' in standard GNU Emacs but since Doom Emacs uses 'SPC' as its leader key and does not have 'SPC z' binded to anything, it just makes since to use it for 'zap-to-char'. Note that 'zap-to-char' can be used with the universal argument 'SPC u' to modify its behavior. Examples of 'zap-to-char' usage are listed in the table below:

KEYBINDING WHAT IS DOES
SPC z e deletes all chars to the next occurrence of 'e'
SPC u 2 SPC z e deletes all chars to the second occurrence of 'e'
SPC u - SPC z e deletes all chars to the previous occurrence of 'e'
SPC u -2 SPC z e deletes all chars to the fourth previous occurrence of 'e'
SPC u 1 0 0 SPC u SPC z e deletes all chars to the 100th occurrence of 'e'

TIP: The universal argument (SPC u) can only take a single integer by default. If you need to use a multi-digit number (like 100 in the last example in the table above), then you must terminate the universal argument with another 'SPC u' after typing the number.

'zap-up-to-char' is an alternative command that does not zap the char specified. It is binded to 'SPC Z'. It can also be used in conjunction with the universal argument 'SPC u' in similar fashion to the the 'zap-to-char' examples above.

NOTE: Vim (evil mode) has similar functionality builtin. You can delete to the next occurrence of 'e' by using 'dte' in normal. To delete to the next occurrence of 'e' including the 'e', then you would use 'dfe'. And you can modify 'dt' and 'df' by prefixing them with numbers, so '2dte' would delete to the second occurrence of 'e'.

(map! :leader
      :desc "Zap to char" "z" #'zap-to-char
      :desc "Zap up to char" "Z" #'zap-up-to-char)
