Doom Emacs Configuration File

Execute doom sync after modifying this file to tangle it to config.el.

The following block of comments is from the default configuration.

;;; $DOOMDIR/config.el -*- lexical-binding: t; -*-

;; Place your private configuration here! Remember, you do not need to run 'doom
;; sync' after modifying this file!

;; Whenever you reconfigure a package, make sure to wrap your config in an
;; `after!' block, otherwise Doom's defaults may override your settings. E.g.
;;
;;   (after! PACKAGE
;;     (setq x y))
;;
;; The exceptions to this rule:
;;
;;   - Setting file/directory variables (like `org-directory')
;;   - Setting variables which explicitly tell you to set them before their
;;     package is loaded (see 'C-h v VARIABLE' to look up their documentation).
;;   - Setting doom variables (which start with 'doom-' or '+').
;;
;; Here are some additional functions/macros that will help you configure Doom.
;;
;; - `load!' for loading external *.el files relative to this one
;; - `use-package!' for configuring packages
;; - `after!' for running code after a package has loaded
;; - `add-load-path!' for adding directories to the `load-path', relative to
;;   this file. Emacs searches the `load-path' when you load packages with
;;   `require' or `use-package'.
;; - `map!' for binding new keys
;;
;; To get information about any of these functions/macros, move the cursor over
;; the highlighted symbol at press 'K' (non-evil users must press 'C-c c k').
;; This will open documentation for it, including demos of how they are used.
;; Alternatively, use `C-h o' to look up a symbol (functions, variables, faces,
;; etc).
;;
;; You can also try 'gd' (or 'C-c c d') to jump to their definition and see how
;; they are implemented.

User specific settings

Some functionality uses this to identify you, e.g. GPG configuration, email clients, file templates and snippets. It is optional. This could be changed to rely on system environment variables.

(setq
	user-full-name "Leni Ven"
	user-mail-address "leniv@stanford.edu")

If you use org and don't want your org files in the default location below, change org-directory. It must be set before org loads!

(setq org-directory "~/org/")

Key Bindings

Modifications to the default key bindings

(setq doom-localleader-key ",") ; Spacemacs like comma major mode
(map! :leader ; "SPC b 0" kills window and buffer
      :desc "Kill buffer and window"
      "b 0" #'kill-buffer-and-window)
(map! :leader ; "SPC :" executes command
      :desc "Execute shell command"
      "!" #'shell-command)
(map! :leader ; "SPC SPC" becomes M-x
      :desc "Execute extended command (emacs M-x)"
      "SPC" #'execute-extended-command)
(map! :leader ; "SPC :" becomes M-:
      :desc "Evaluate expression (emacs M-:)"
      ":" #'eval-expression)
(after! magit
	(map! :localleader
		(:map git-commit-mode-map
		"c" #'with-editor-finish)
		(:map git-commit-mode-map
		"q" #'with-editor-cancel)
	))
(after! org
	(map! :localleader
		(:map org-mode-map
		"X" #'org-latex-preview)
	))

Font settings

Doom exposes five (optional) variables for controlling fonts in Doom:

  • doom-font the primary font to use
  • doom-variable-pitch-font a non-monospace font (where applicable)
  • doom-big-font used for doom-big-font-mode; use this for presentations or streaming.
  • doom-unicode-font for unicode glyphs
  • doom-serif-font for the fixed-pitch-serif face

See C-h v doom-font for documentation and more examples of what they accept.

If you or Emacs can't find your font, use M-x describe-font to look them up, M-x eval-region to execute ELisp code, and M-x doom/reload-font to refresh your font settings. If Emacs still can't find your font, it likely wasn't installed correctly. Font issues are rarely Doom issues!

There are two ways to load a theme. Both assume the theme is installed and available. You can either set doom-theme or manually load a theme with the load-theme function.

(setq
	default-font "Source Code Pro"
	default-font-size 14.0
	doom-font (font-spec
		:family default-font
		:size default-font-size
		:weight 'semi-light)
	doom-variable-pitch-font (font-spec
		:family default-font
		:size (+ default-font-size 1.0))
	doom-unicode-font (font-spec
		:family default-font
		:size default-font-size)
	doom-theme 'doom-lantern)

Display and Indentation Styles

Line numbers

This determines the style of line numbers in effect. If set to nil, line numbers are disabled. For relative line numbers, set this to relative.

(setq display-line-numbers-type 'relative)
(global-display-line-numbers-mode)

Whitespace mode

(use-package! whitespace
	:config
	(setq
		whitespace-style '(face tabs tab-mark spaces space-mark trailing newline newline-mark)
		whitespace-line-column 80
		whitespace-display-mappings
		'(
			(space-mark 32 [183] [46]) ; 32 SPACE 「 」, 183 MIDDLE DOT 「·」, 46 FULL STOP 「.」
			(newline-mark 10 [172 10]) ; 10 LINE FEED, 172 Not Sign「¬」
			(tab-mark 9 [10141 9] [92 9]) ; 9 TAB, 10141 Triangle-headed rightwards arrow 「➝」
		))
	(global-whitespace-mode +1)
	)

	Item 1 continued. 1 level of indentation.
\item

Package Loading

These packages are loaded into packages.el. The following comments are provided by default.

;; -*- no-byte-compile: t; -*-
;;; $DOOMDIR/packages.el

;; To install a package with Doom you must declare them here and run 'doom sync'
;; on the command line, then restart Emacs for the changes to take effect -- or
;; use 'M-x doom/reload'.


;; To install SOME-PACKAGE from MELPA, ELPA or emacsmirror:
;(package! some-package)

;; To install a package directly from a remote git repo, you must specify a
;; `:recipe'. You'll find documentation on what `:recipe' accepts here:
;; https://github.com/radian-software/straight.el#the-recipe-format
;(package! another-package
;  :recipe (:host github :repo "username/repo"))

;; If the package you are trying to install does not contain a PACKAGENAME.el
;; file, or is located in a subdirectory of the repo, you'll need to specify
;; `:files' in the `:recipe':
;(package! this-package
;  :recipe (:host github :repo "username/repo"
;           :files ("some-file.el" "src/lisp/*.el")))

;; If you'd like to disable a package included with Doom, you can do so here
;; with the `:disable' property:
;(package! builtin-package :disable t)

;; You can override the recipe of a built in package without having to specify
;; all the properties for `:recipe'. These will inherit the rest of its recipe
;; from Doom or MELPA/ELPA/Emacsmirror:
;(package! builtin-package :recipe (:nonrecursive t))
;(package! builtin-package-2 :recipe (:repo "myfork/package"))

;; Specify a `:branch' to install a package from a particular branch or tag.
;; This is required for some packages whose default branch isn't 'master' (which
;; our package manager can't deal with; see radian-software/straight.el#279)
;(package! builtin-package :recipe (:branch "develop"))

;; Use `:pin' to specify a particular commit to install.
;(package! builtin-package :pin "1a2b3c4d5e")


;; Doom's packages are pinned to a specific commit and updated from release to
;; release. The `unpin!' macro allows you to unpin single packages...
;(unpin! pinned-package)
;; ...or multiple packages
;(unpin! pinned-package another-pinned-package)
;; ...Or *all* packages (NOT RECOMMENDED; will likely break things)
;(unpin! t)
(package! whitespace)
(package! smart-tabs-mode)
