  6*Note:* you do not need to run ~doom sync~ after modifying this file!

 10Here are some additional functions/macros that could help configure Doom:
 11
 12- ~load!~ for loading external ~*.el~ files relative to this one
 13- ~use-package!~ for configuring packages
 14- ~after!~ for running code after a package has loaded
 15- ~add-load-path!~ for adding directories to the ~load-path~, relative to
 16  this file. Emacs searches the ~load-path~ when loading packages with
 17  ~require~ or ~use-package~.
 18- ~map!~ for binding new keys
 19
 20To get information about any of these functions/macros, move the cursor over the
 21highlighted symbol at press ~K~ (non-evil users must press ~C-c c k~). This will
 22open documentation for it, including demos of how they're used. ~gd~ (or ~C-c c d~)
 23will also jump to their definition for viewing how they're implemented.
 24
 25First off, enable [[https://www.emacswiki.org/emacs/DynamicBindingVsLexicalBinding][lexical binding]]:
 26#+BEGIN_SRC emacs-lisp
 27;;; $DOOMDIR/config.el -*- lexical-binding: t; -*-
 28#+END_SRC
 29
 30* Identity configuration
 31Some functionality uses this to identify the user, e.g. GPG configuration, email
 32clients, file templates and snippets.
 33#+BEGIN_SRC emacs-lisp
 34(setq user-full-name "Amolith"
 35      user-mail-address "amolith@secluded.site")
 36#+END_SRC
 37
 38* UI settings
 39Doom exposes five (optional) variables for controlling fonts in Doom. Here
 40are the three important ones:
 41
 42+ ~doom-font~
 43+ ~doom-variable-pitch-font~
 44+ ~doom-big-font~ — used for ~doom-big-font-mode~; use this for
 45  presentations or streaming.
 46
 47They all accept either a font-spec, font string (~"Input Mono-12"~), or ~xlfd~
 48font string. Generally, only these two are needed:
 49#+BEGIN_SRC emacs-lisp
 50(setq doom-font (font-spec :family "Triplicate A Code" :size 16)
 51      doom-variable-pitch-font (font-spec :family "Triplicate A Code" :size 16))
 52#+END_SRC
 53
 54There are two ways to load a theme. Both assume the theme is installed and
 55available. Either set ~doom-theme~ or manually load a theme with the ~load-theme~
 56function.
 57#+BEGIN_SRC emacs-lisp
 58{{- if eq .theme_variant "dark"}}
 59(setq doom-theme 'doom-dracula)
 60{{- end }}
 61{{- if eq .theme_variant "light"}}
 62(setq doom-theme 'doom-one-light)
 63{{- end }}
 64#+END_SRC
 65
 66This determines the style of line numbers in effect. Disable line numbers by
 67setting it this to ~nil~. For relative line numbers, set this to ~relative~.
 68#+BEGIN_SRC emacs-lisp
 69(setq display-line-numbers-type t)
 70#+END_SRC
 71
 72Keep point in about the centre of the screen
 73#+BEGIN_SRC emacs-lisp
 74(use-package smooth-scrolling
 75  :ensure t
 76  :config
 77  (smooth-scrolling-mode 1)
 78  (setq smooth-scroll-margin 20))
 79#+END_SRC
 80
 81Use fancy lambdas
 82#+BEGIN_SRC emacs-lisp
 83(global-prettify-symbols-mode t)
 84#+END_SRC
 85
 86When splitting windows, I want to switch to the new one immediately. By default,
 87you have to press a few bindings. This makes that automatic.
 88#+BEGIN_SRC emacs-lisp
 89(defun amo/split-window-below-and-switch ()
 90  "Split the window horizontally, then switch to the new pane."
 91  (interactive)
 92  (split-window-below)
 93  (balance-windows)
 94  (other-window 1))
 95(defun amo/split-window-right-and-switch ()
 96  "Split the window vertically, then switch to the new pane."
 97  (interactive)
 98  (split-window-right)
 99  (balance-windows)
100  (other-window 1))
101(global-set-key (kbd "C-x 2") 'amo/split-window-below-and-switch)
102(global-set-key (kbd "C-x 3") 'amo/split-window-right-and-switch)
103#+END_SRC
104
105** LSP Settings
106#+BEGIN_SRC emacs-lisp
107(setq lsp-ui-doc-max-height 13)
108(setq lsp-ui-doc-show-with-cursor t)
109#+END_SRC
110
111* Org Mode settings
112If you use ~org~ and don't want your org files in the default location below,
113change ~org-directory~. It must be set before org loads!
114#+BEGIN_SRC emacs-lisp
115(setq org-directory "~/Org/")
116#+END_SRC
117
118Prettify bullets
119#+BEGIN_SRC emacs-lisp
120(use-package org-bullets
121  :init
122  (add-hook 'org-mode-hook 'org-bullets-mode))
123#+END_SRC
124
125Replace ellipsis with downward-pointing arrow
126#+BEGIN_SRC emacs-lisp
127(setq org-ellipsis " ⤵")
128#+END_SRC
129
130Format Org text and hide markers
131#+BEGIN_SRC emacs-lisp

143(require 'ox-beamer)
144#+END_SRC
145
146Don't ask before evaluating code blocks
147#+BEGIN_SRC emacs-lisp
148(setq org-confirm-babel-evaluate nil)
149#+END_SRC
150
151Use =htmlize= to ensure that exported code blocks use syntax highlighting.
152#+BEGIN_SRC emacs-lisp
153(use-package htmlize)
154#+END_SRC
155
156Translate regular old straight quotes to typographically-correct curly quotes
157when exporting.
158#+BEGIN_SRC emacs-lisp
159(setq org-export-with-smart-quotes t)

179(add-to-list 'auto-mode-alist '("/tmp/neomutt-*" . mail-mode))
180#+END_SRC
181
182Always use =pdflatex= when compiling LaTeX documents. I don't really have any use
183for DVIs.
184#+BEGIN_SRC emacs-lisp
185(setq TeX-PDF-mode t)
186#+END_SRC
187
188** Music
189I've taken to charting my guitar music out with [[https://www.chordpro.org][ChordPro]]. [[https://github.com/sciurius/chordpro-mode][Chordpro mode]] just
190adds a major mode for syntax highlighting and some keybinds.
191#+BEGIN_SRC emacs-lisp
192(setq auto-mode-alist (cons '("\\.cho$" . chordpro-mode) auto-mode-alist))
193(autoload 'chordpro-mode "chordpro-mode")
194#+END_SRC
195
196I use [[https://lilypond.org/][LilyPond]] for writing standard sheet music. When you install the package,
197it comes with some elisp files that Emacs needs to load and configure.
198#+BEGIN_SRC emacs-lisp
199(require 'lilypond-mode)
200(add-to-list 'auto-mode-alist '("\\.ly$" . LilyPond-mode))

218          prose-modes))
219#+END_SRC

253  (add-to-list 'exec-path path))
254#+END_SRC
255
256Look for various executables
