 * macOS installation info
 On macOS, I use Homebrew to install Emacs from daviderestivo/emacs-head/emacs-head@28.
 I install with ~--HEAD --with-dbus --with-cocoa --with-xwidgets --with-native-comp~.
 
 * Why I choose use-package
 - provides bind-key by default
 - is mostly just macros that wrap the needed stuff from package.el. can check that with ~macroexpand~.
 - adds a bunch of performance improvements
 * Let me know when we're at a certain version
 #+begin_src emacs-lisp
   (when (version<= "30" emacs-version)
     (message "Check out C-x w d to make windows dedicated."))
 #+end_src
 * Install from source
 Emacs 29 ships with a way to install packages from source, here's a small wrapper around it.
 
 #+begin_src emacs-lisp
   (cl-defun za/package-vc-install (&key (fetcher "github") repo name rev backend load)
     "Install a package from a remote if it's not already installed.
   This is a thin wrapper around `package-vc-install' in order to
   make non-interactive usage more ergonomic.  Takes the following
   named arguments:
 
   - FETCHER the remote where to get the package (e.g., \"gitlab\").
     If omitted, this defaults to \"github\".
 
   - REPO should be the name of the repository (e.g.,
   \"slotThe/arXiv-citation\".
 
   - NAME, REV, and BACKEND are as in `package-vc-install' (which
     see).
 
   - LOAD is optionally a subdirectory that should be added to `load-path'."
     (let* ((url (cond ((string-match-p (rx bos "http" (? ?s) "://") repo)
                        repo)
                       (t (format "https://www.%s.com/%s" fetcher repo))))
            (iname (when name (intern name)))
            (pac-name (or iname (intern (file-name-base repo))))
            (to-load (when load
                       (format "%s/%s"
                               (package-desc-dir (package-get-descriptor pac-name))
                               load))))
       (unless (package-installed-p pac-name)
         (package-vc-install url rev backend iname))
       (when load
         (unless (file-directory-p to-load)
           (user-error "Not a readable dir: %s" to-load))
         (add-to-list 'load-path to-load))
       (message "%s" pac-name)))
 #+end_src
 
 You can use this in use-package with an ~:init~ clause.
 
 * exec-path-from-shell (macOS)
 In macOS, the path is not set correctly (i.e. as it is in the terminal) in the GUI app. This fixes it.
 Not needed when using emacs-plus, because it has a custom patch for it. It also defines a [[https://github.com/d12frosted/homebrew-emacs-plus?tab=readme-ov-file#system-appearance-change][custom variable]] which hopefully should be enough to detect if we're running emacs-plus.
 
 #+begin_src emacs-lisp
   (when (and (string-equal system-type "darwin")
              (not (boundp 'ns-system-appearance-change-functions)))
     (use-package exec-path-from-shell
       :config
       (add-to-list 'exec-path-from-shell-variables "NOTMUCH_CONFIG")
       (exec-path-from-shell-initialize)))
 #+end_src
 
 * Emacs file locations
 ** Auto-Save files
 By default, auto-save files ("#file#") are placed in the same directory as the file itself.
 I want to put this all in some unified place:
 
 #+begin_src emacs-lisp
   (let ((saves-directory "~/.local/share/emacs/saves/"))
     (unless (file-directory-p saves-directory)
       (make-directory saves-directory))
     (setq auto-save-file-name-transforms
           `((".*" ,saves-directory t))))
 #+end_src
 
 ** Backup files
 By default, backup files (those with a tilde) are saved in the same directory as the currently edited file.
 This setting puts them in ~/.local/share/emacs/backups.
 
 #+begin_src emacs-lisp
   (let ((backups-directory "~/.local/share/emacs/backups"))
     (unless (file-directory-p backups-directory)
       (make-directory backups-directory))
     (setq backup-directory-alist `(("." . ,backups-directory)))
     (setq backup-by-copying t))
 #+end_src
 
 ** Custom settings file
 Both commands are necessary.
 First one tells Emacs where to save customizations.
 The second one actually loads them.
 
 #+begin_src emacs-lisp
   (setq custom-file (expand-file-name (concat user-emacs-directory "custom.el")))
   (load custom-file)
 #+end_src
 ** Delete by trash
 #+begin_src emacs-lisp
   (setq delete-by-moving-to-trash t)
   (unless (fboundp 'system-move-file-to-trash)
     (setq trash-directory "~/.Trash"))
 #+end_src
 * Daemon
 I want to have a way to kill the Emacs daemon.
 So, define a function that kills the frame, and with a prefix kills emacs.
 
 #+begin_src emacs-lisp
   (defun za/emacsclient-c-x-c-c (&optional arg)
     "If running in emacsclient, make C-x C-c exit frame, and C-u C-x C-c exit Emacs."
     (interactive "P") ; prefix arg in raw form
     (if arg
         (save-buffers-kill-emacs)
       (save-buffers-kill-terminal)))
 #+end_src
 
 Then, if I'm in an emacsclient, I want to bind C-x C-c to that function (if not, I just want the default keybinding):
 
 #+begin_src emacs-lisp
   ;; If not running in emacsclient, use the default bindings
   (if (daemonp)
       (bind-key "C-x C-c" #'za/emacsclient-c-x-c-c))
 #+end_src
 
 Furthermore, I want to set the theme correctly whenever I connect with 'emacsclient':
 
 #+begin_src emacs-lisp
   (if (daemonp)
       (add-hook 'after-make-frame-functions #'za/auto-select-theme))
 #+end_src
 * Sound support
 On macOS, you can use afplay:
 
 #+begin_src emacs-lisp
   (defun za/play-sound-file-macos (file &optional volume device)
     "Play sound using `afplay` on macOS"
     (unless (file-readable-p file)
       (user-error "File %s not readable." file))
 
     ;; the `apply` is required here because I need to build a list of arguments
     (apply 'start-process `("afplay" nil
                             "afplay"
                             ,@(if volume (list "-v" (int-to-string volume)))
                             ,file)))
 #+end_src
 
 Then redefine the play-sound-file function where needed:
 
 #+begin_src emacs-lisp
   (cond ((and (not (fboundp 'play-sound-internal))
               (eq system-type 'darwin))
          (advice-add 'play-sound-file :override #'za/play-sound-file-macos)))
 #+end_src
 * DISABLED Fix non-dbus macOS notification
 macOS version might not be compiled with dbus support; in that case you can use e.g. terminal-notifier.
 If you use the ~sender~ option, notifications don't show
 unless the app is in the background. [[https://github.com/julienXX/terminal-notifier/issues/68][See this Github issue.]]
 
 #+begin_src emacs-lisp :tangle no
   ;; on mac without dbus:
   (org-show-notification-handler
    (lambda (str) (start-process "terminal-notifier" nil (executable-find "terminal-notifier")
                                 "-title" "Timer done"
                                 "-message" str
                                 "-group" "org.gnu.Emacs"
                                 "-ignoreDnD"
                                 "-activate" "org.gnu.Emacs")))
 #+end_src
 * Custom notification functions
 #+begin_src emacs-lisp
   (defun za/notify (title message)
     "Show notification with TITLE and MESSAGE."
     (ignore-errors (require 'notifications))
     (cond ((fboundp 'ns-do-applescript)
            (ns-do-applescript
             (format "display notification \"%s\" with title \"%s\""
                     (replace-regexp-in-string "\"" "#" message)
                     (replace-regexp-in-string "\"" "#" title))))
           ((string= system-type "gnu/linux")
            (require 'notifications)
            (notifications-notify :title title :body message))
           (t (error "No notification handler defined!"))))
 
   (defun za/send-notification-interactivity-required (&rest _)
     "Notify that a function needs action."
     (za/notify "Interactivity required" "A function requires interactivity."))
 
   (defun za/notify-on-interactivity (func &rest r)
     "Send a notification whenever FUNC requires interactivity.
   Used as :around advice, calling FUNC with arguments R."
     (advice-add #'y-or-n-p :before #'za/send-notification-interactivity-required)
     (advice-add #'yes-or-no-p :before #'za/send-notification-interactivity-required)
     (advice-add #'user-error :before #'za/send-notification-interactivity-required)
     (with-demoted-errors "Error in %s" (apply func r))
     (advice-remove #'y-or-n-p #'za/send-notification-interactivity-required)
     (advice-remove #'yes-or-no-p #'za/send-notification-interactivity-required)
     (advice-remove #'user-error #'za/send-notification-interactivity-required))
 #+end_src
 
 * URLs
 #+begin_src emacs-lisp
   (defun za/browse-url-quicksilver (url &rest args)
     (call-process-shell-command (format "printf '%s' | qs -" url)))
   (setopt browse-url-handlers `((,(rx "http" (? ?s) "://") . za/browse-url-quicksilver)))
 #+end_src
 * Editing
 ** Everything is UTF-8
 #+begin_src emacs-lisp
   (set-language-environment 'utf-8)
   (setq locale-coding-system 'utf-8)
   (setq buffer-file-coding-system 'utf-8-unix)
   (set-terminal-coding-system 'utf-8)
   (set-keyboard-coding-system 'utf-8)
   (set-selection-coding-system 'utf-8)
   (prefer-coding-system 'utf-8)
 #+end_src
 ** Overwrite selection on typing
 Normally, when I select something and start typing, Emacs clears the selection, i.e. it deselects and inserts text after the cursor.
 I want to replace the selection.
 
 #+begin_src emacs-lisp
   (delete-selection-mode t)
 #+end_src
 
 ** Strip trailing whitespace
 You can show trailing whitespace by setting show-trailing-whitespace to 't'.
 But I want to automatically strip trailing whitespace.
 Luckily there's already a function for that, I just need to call it in a hook:
 
 #+begin_src emacs-lisp
   (add-hook 'before-save-hook #'delete-trailing-whitespace)
 #+end_src
 
 ** Formatting & indentation
 
 Show a tab as 8 spaces:
 
 #+begin_src emacs-lisp
   (setq-default tab-width 8)
 #+end_src
 
 Never insert tabs with indentation by default:
 
 #+begin_src emacs-lisp
   (setq-default indent-tabs-mode nil)
 #+end_src
 
 Allow switching between the two easily:
 
 #+begin_src emacs-lisp
   (defun indent-tabs ()
     (interactive)
     (setq indent-tabs-mode t))
   (defun indent-spaces ()
     (interactive)
     (setq indent-tabs-mode nil))
 #+end_src
 
 Indentation for various modes:
 
 #+begin_src emacs-lisp
   (setq-default sh-basic-offset 2
                 c-basic-offset 4)
 #+end_src
 
 ** Wrapping
 A function to toggle wrapping:
 
 #+begin_src emacs-lisp
   (defvar-local za/wrapping nil "Wrapping changes per buffer.")
 
   (defun za/toggle-wrap (&optional enable)
     "Toggle line wrapping settings. With ENABLE a positive number, enable wrapping. If ENABLE is negative or zero, disable wrapping."
     (interactive "P") ; prefix arg in raw form
 
     ;; If an argument is provided, prefix or otherwise
     (if enable
         (let ((enable (cond ((numberp enable)
                              enable)
                             ((booleanp enable)
                              (if enable 1 0))
                             ((or (listp enable) (string= "-" enable))
                              (prefix-numeric-value enable)))))
           ;; If zero or negative, we want to disable wrapping, so pretend it's currently enabled.
           ;; And vice versa.
           (cond ((<= enable 0) (setq za/wrapping t))
                 ((> enable 0) (setq za/wrapping nil)))))
 
 
     (let ((disable-wrapping (lambda ()
                               (visual-line-mode -1)
                               (toggle-truncate-lines t)))
           (enable-wrapping (lambda ()
                              (toggle-truncate-lines -1)
                              (visual-line-mode))))
 
       ;; If za/wrapping is not locally set, infer its values from the enabled modes
       (unless (boundp 'za/wrapping)
         (setq za/wrapping (and visual-line-mode
                                (not truncate-lines))))
 
       ;; Toggle wrapping based on current value
       (cond (za/wrapping
              (funcall disable-wrapping)
              (setq za/wrapping nil)
              (message "Wrapping disabled."))
             (t
              (funcall enable-wrapping)
              (setq za/wrapping t)
              (message "Wrapping enabled.")))))
 #+end_src
 
 And a keybinding to toggle wrapping:
 
 #+begin_src emacs-lisp
   (bind-key "C-c q w" #'za/toggle-wrap)
 #+end_src
 
 And fringe indicators:
 
 #+begin_src emacs-lisp
   (setopt visual-line-fringe-indicators '(left-curly-arrow right-curly-arrow))
 #+end_src
 ** Pager toggle
 M-x view-mode enables pager behavior.
 I want read-only files to automatically use pager mode:
 
 #+begin_src emacs-lisp
   (setq view-read-only t)
 #+end_src
 ** Prefer newer file loading
 #+begin_src emacs-lisp
   (setq load-prefer-newer t)
 #+end_src
 
 ** Automatically find tags file
 When opening a file in a git repo, try to discover the etags file:
 
 #+begin_src emacs-lisp
   (defun current-tags-file ()
     "Get current tags file"
     (let* ((tagspath ".git/etags")
            (git-root (locate-dominating-file (buffer-file-name) tagspath)))
       (if git-root
           (expand-file-name tagspath git-root))))
 
   (setq default-tags-table-function #'current-tags-file)
 #+end_src
 
 There's probably a better way to write this. I need to ask Reddit for feedback at some point.
 
 ** End sentences with one space
 Emacs uses the rather old-fashioned convention of treating a period followed by double spaces as end of sentence. However, it is more common these days to end sentences with a period followed by a single space.
 
 Let a period followed by a single space be treated as end of sentence:
 
 #+begin_src emacs-lisp
   (setopt sentence-end-double-space nil)
 #+end_src
 * Keybindings
 ** Expansion/completion
 Use hippie expand instead of dabbrev-expand:
 
 #+begin_src emacs-lisp
   (bind-key "M-/" #'hippie-expand)
 #+end_src
 
 ** Zap up to char
 It's more useful for me to be able to delete up to a character instead of to and including a character:
 
 #+begin_src emacs-lisp
   (defun za/zap-up-to-char-icase ()
     "Ignore case for zap-up-to-char"
     (interactive)
     (let ((case-fold-search nil))
       (call-interactively #'zap-up-to-char)))
   (bind-key "M-z" #'za/zap-up-to-char-icase)
 #+end_src
 
 ** Forward-word and forward-to-word
 Change M-f to stop at the start of the word:
 
 #+begin_src emacs-lisp
   (bind-key "M-f" #'forward-to-word)
 #+end_src
 
 Bind ESC M-f to the old functionality of M-f (stop at end of word)
 
 #+begin_src emacs-lisp
   (bind-key "ESC M-f" #'forward-word)
 #+end_src
 
 ** Rectangle insert string
 #+begin_src emacs-lisp
   (bind-key "C-x r I" #'string-insert-rectangle)
   (bind-key "C-x r R" #'replace-rectangle)
 #+end_src
 
 ** Toggle auto-revert-mode
 Sometimes I want to toggle auto reverting (or autoread) of buffer:
 
 #+begin_src emacs-lisp
   (bind-key "C-c q a" #'auto-revert-mode)
 #+end_src
 ** Fast access to view-mode (pager)
 I want to bind view-mode to a key for easy access:
 
 #+begin_src emacs-lisp
   (bind-key "C-c q r" 'view-mode)
 #+end_src
 
 ** Kill this buffer
 I like to be able to kill a buffer instantly:
 
 #+begin_src emacs-lisp
   (bind-key "s-<backspace>" 'kill-current-buffer)
 #+end_src
 
 ** Delete this file (and kill the buffer)
 #+begin_src emacs-lisp
   (defun za/delete-this-file ()
     "Kill the current buffer and delete its associated file."
     (interactive)
     (let ((fname (buffer-file-name))
           (buf (current-buffer)))
       (unless (and fname (file-exists-p fname))
         (user-error "Buffer has no associated file."))
 
       (unless (yes-or-no-p (format "Really delete %s and its buffer?" fname))
         (user-error "User cancelled."))
 
       (delete-file fname 'trash-if-enabled)
       (kill-buffer buf)
       (message "Deleted %s and killed its buffer." fname)))
 
   (bind-key "C-c s-<backspace>" #'za/delete-this-file)
 #+end_src
 
 ** Toggle fullscreen
 I'll use the keybinding that's standard on macOS:
 
 #+begin_src emacs-lisp
   (bind-key "C-s-f" #'toggle-frame-fullscreen)
 #+end_src
 
 ** Sexp manipulation
 When I write lisp, sometimes I want to switch two sexps (e.g. ~(one) (two)~ → ~(two) (one)~), so a key binding is nice for that:
 
 #+begin_src emacs-lisp
   (bind-key "C-S-t" #'transpose-sexps)
 #+end_src
 
 Also, to raise a sexp (e.g. ~(one (two))~ → ~(two)~):
 
 #+begin_src emacs-lisp
   (bind-key "C-S-u" #'raise-sexp)
 #+end_src
 
 ** Dedicated windows
 Sometimes I want to avoid Emacs overriding a window's contents.
 So I create a keybinding to toggle dedicated on a window:
 
 #+begin_src emacs-lisp
   (defun za/toggle-window-dedicated-p ()
     "Toggle set-window-dedicated-p on current window"
     (interactive)
     (cond ((window-dedicated-p (selected-window))
            (set-window-dedicated-p (selected-window) nil)
            (message "Window no longer dedicated"))
           (t
            (set-window-dedicated-p (selected-window) t)
            (message "Window marked as dedicated"))))
 
   (bind-key "C-x 9" #'za/toggle-window-dedicated-p)
 
 #+end_src
 
 ** Rotate windows horizontal ↔ vertical
 #+begin_src emacs-lisp
   (defun za/rotate-windows ()
     (interactive)
     (if (= (count-windows) 2)
         (let* ((this-win-buffer (window-buffer))
                (next-win-buffer (window-buffer (next-window)))
                (this-win-edges (window-edges (selected-window)))
                (next-win-edges (window-edges (next-window)))
                (this-win-2nd (not (and (<= (car this-win-edges)
                                            (car next-win-edges))
                                        (<= (cadr this-win-edges)
                                            (cadr next-win-edges)))))
                (splitter
                 (if (= (car this-win-edges)
                        (car (window-edges (next-window))))
                     'split-window-horizontally
                   'split-window-vertically)))
           (delete-other-windows)
           (let ((first-win (selected-window)))
             (funcall splitter)
             (if this-win-2nd (other-window 1))
             (set-window-buffer (selected-window) this-win-buffer)
             (set-window-buffer (next-window) next-win-buffer)
             (select-window first-win)
             (if this-win-2nd (other-window 1))))))
 #+end_src
 
 #+begin_src emacs-lisp
   (bind-key "C-x 7" #'za/rotate-windows)
 #+end_src
 
 ** Open line like in Vim
 I prefer to open-line the way o/O works in Vim:
 
 #+begin_src emacs-lisp
   ;; Autoindent open-*-lines
   (defvar za/open-line-newline-and-indent t
     "Modify the behavior of the open-*-line functions to cause them to autoindent.")
 
   (defun za/open-line (prefix)
     "Open line like `o`/`O` in Vim. Negative prefix for line above, positive for below."
     (interactive "p")
     (cond ((< prefix 0)
            (beginning-of-line)
            (open-line (abs prefix)))

 ** Theme
 Icons required for some parts of the doom theme:
 
 #+begin_src emacs-lisp
   (use-package all-the-icons)
 #+end_src
 
 Load Doom Emacs themes:
 
 #+begin_src emacs-lisp
   (use-package doom-themes
     :config
     ;; Global settings (defaults)
     (setq doom-themes-enable-bold t    ; if nil, bold is universally disabled
           doom-themes-enable-italic t) ; if nil, italics is universally disabled
 
     ;; Enable flashing mode-line on errors
     (doom-themes-visual-bell-config)
 
     ;; Corrects (and improves) org-mode's native fontification.
     (doom-themes-org-config))
 #+end_src
 
 Define the themes I want:
 
 #+begin_src emacs-lisp
   (defconst za/dark-theme-name 'doom-one "A symbol representing the name of the dark theme I use.")
   (defconst za/light-theme-name 'jokull "A symbol representing the name of the light theme I use.")
   ;; I used to use doom-acario-light before writing my own theme
 
   (defun za/dark-theme ()
     "Switch to dark theme"
     (interactive)
     (mapc #'disable-theme custom-enabled-themes)
     (load-theme za/dark-theme-name t)
     (add-hook 'pdf-view-mode-hook #'pdf-view-midnight-minor-mode))
 
   (defun za/light-theme ()
     "Switch to light theme"
     (interactive)
     (mapc #'disable-theme custom-enabled-themes)
     (load-theme za/light-theme-name t)
     (remove-hook 'pdf-view-mode-hook #'pdf-view-midnight-minor-mode))
 #+end_src
 
 Change theme depending on the current system theme.
 The way I check for dark mode is defined in 'dark-mode-p'; currently I use the presence of the ~/.config/dark-theme file to indicate when dark theme is set.
 I quote the call to ~file-exists-p~ because I want to evaluate it on-demand, not immediately.
 A function ending in '-p' is a predicate, i.e. returns true or false.
 If calling a function that's in a variable, you have to use 'funcall'.
 To evaluate a quoted form, use 'eval'.
 
 #+begin_src emacs-lisp
   (defun za/auto-select-theme (&rest _)
     "Automatically select dark/light theme based on presence of ~/.config/dark-theme"
     (let ((dark-mode-p '(file-exists-p "~/.config/dark-theme")))
       (if (eval dark-mode-p)
           (za/dark-theme)
         (za/light-theme))))
 
   (za/auto-select-theme)
 #+end_src
 
 ** Font
 I want Menlo, size 12:
 
 #+begin_src emacs-lisp
   (add-to-list 'default-frame-alist '(font . "Menlo-13"))
   (custom-set-faces
    ; height = pt * 10
    '(fixed-pitch ((t (:family "Menlo" :height 130))))
    '(variable-pitch ((t (:family "ETBembo" :height 140))))
    '(org-block ((t (:inherit fixed-pitch))))
    '(org-table ((t (:foreground "#0087af" :inherit fixed-pitch))))
    '(org-indent ((t (:inherit (org-hide fixed-pitch))))))
 
   (set-face-font 'fixed-pitch "Menlo-13")
   (set-face-font 'variable-pitch "ETBembo-14")
 #+end_src
 
 I like nicer list bullets:
 
 #+begin_src emacs-lisp
   (font-lock-add-keywords
    'org-mode
    `((,(rx bol (* blank) (group ?-) " ")  ; list regexp
       1                                   ; first match
       '(face nil display "•"))))          ; replace with bullet point, keep same face
 #+end_src
 ** Cursor
 The default box cursor isn't really accurate, because the cursor is actually between letters, not on a letter.
 So, I want a bar instead of a box:
 
 #+begin_src emacs-lisp
   (setq-default cursor-type '(bar . 4)
                 cursor-in-non-selected-windows 'hollow)
 #+end_src
 
 (I use ~setq-default~ here because cursor-type is automatically buffer-local when it's set)
 
 And enable cursorline:
 
 #+begin_src emacs-lisp
   (global-hl-line-mode)
 #+end_src
 
 And visualize tab characters by stretching the cursor:
 
 #+begin_src emacs-lisp
   (setq-default x-stretch-cursor t)
 #+end_src
 ** Matching parentheses
 Don't add a delay to show matching parenthesis.
 Must come before show-paren-mode enable.
 
 #+begin_src emacs-lisp
   (setq show-paren-delay 0)
 #+end_src
 
 Show matching parentheses:
 
 #+begin_src emacs-lisp
   (show-paren-mode t)
 #+end_src
 ** Line numbers
 Relative line numbers:
 
 #+begin_src emacs-lisp
   (setq display-line-numbers-type 'relative)
   (global-display-line-numbers-mode)
 #+end_src
 
 Function to hide them:
 
 #+begin_src emacs-lisp
   (defun za/hide-line-numbers ()
     "Hide line numbers"
     (display-line-numbers-mode 0))
 #+end_src
 Don't display them in specific modes.  For each of the modes in
 'mode-hooks', add a function to hide line numbers when the mode
 activates (which triggers the 'mode'-hook).
 
 #+begin_src emacs-lisp
   (let ((mode-hooks '(doc-view-mode-hook vterm-mode-hook mpc-status-mode-hook mpc-tagbrowser-mode-hook)))
     (mapc
      (lambda (mode-name)
        (add-hook mode-name #'za/hide-line-numbers))
      mode-hooks))
 #+end_src
 ** Modeline
 I want to show the time and date in the modeline:
 
 #+begin_src emacs-lisp
   (setq display-time-day-and-date t           ; also the date
         display-time-default-load-average nil ; don't show load average
         display-time-format "%I:%M%p %e %b (%a)")   ; "HR:MIN(AM/PM) day-of-month Month (Day)"
   (display-time-mode 1)                  ; enable time mode
 #+end_src
 
 And to set the modeline format:
 
 #+begin_src emacs-lisp
   (setq-default mode-line-format '("%e" mode-line-front-space mode-line-mule-info mode-line-client mode-line-modified mode-line-remote mode-line-frame-identification mode-line-buffer-identification "   " mode-line-position
                                    (vc-mode vc-mode)
                                    "  " mode-line-modes mode-line-misc-info mode-line-end-spaces))
 #+end_src
 
 I want to hide certain modes from the modeline.
 For that, ~delight~ is a useful package; unlike ~diminish~, it can also change the display of /major/ modes (~diminish~ only does minor modes).
 
 #+begin_src emacs-lisp
     (use-package delight
       :config
       (delight 'visual-line-mode " ↩" 'simple)
       (delight 'auto-revert-mode " AR" 'autorevert)
       (delight 'abbrev-mode " Abv" 'abbrev))
 #+end_src
 ** Transparent title bar
 #+begin_src emacs-lisp
   (add-to-list 'default-frame-alist '(ns-transparent-titlebar . t))
 #+end_src
 ** Frame title
 #+begin_src emacs-lisp
   (setopt frame-title-format "%F--%b-[%f]--%Z")
 #+end_src
 
 ** Tab bar
 Only show tab bar if there's more than 1 tab:
 
 #+begin_src emacs-lisp
   (setq tab-bar-show 1)
 #+end_src
 ** Buffer displaying
 
 So, this is a bit hard to grok. But basically the alist contains a
 regular expression to match a buffer name, then a list of functions to
 use in order for displaying the list, and then options for those functions (each of which is an alist).
 
 #+begin_src emacs-lisp

 And a way to toggle those side windows:
 
 #+begin_src emacs-lisp
   (bind-key "C-c W" #'window-toggle-side-windows)
 #+end_src
 
 ** Eldoc
 When editing Elisp and other supported major-modes, Eldoc will display useful information about the construct at point in the echo area.
 
 #+begin_src emacs-lisp

     :delight
     :config
     (global-eldoc-mode 1))
 #+end_src
 
 ** Pulse line
 When you switch windows, Emacs can flash the cursor briefly to guide your eyes; I like that.
 Set some options for pulsing:
 
 #+begin_src emacs-lisp
   (setq pulse-iterations 10)
   (setq pulse-delay 0.05)
 #+end_src
 
 Define the pulse function:
 
 #+begin_src emacs-lisp
   (defun pulse-line (&rest _)
     "Pulse the current line."
     (pulse-momentary-highlight-one-line (point)))
 #+end_src
 
 Run it in certain cases: scrolling up/down, recentering, switching windows.
 'dolist' binds 'command' to each value in the list in turn, and runs the body.
 'advice-add' makes the pulse-line function run after 'command'.
 
 #+begin_src emacs-lisp
   (dolist (command '(scroll-up-command scroll-down-command recenter-top-bottom other-window))
     (advice-add command :after #'pulse-line))
 #+end_src
 
 And set the pulse color:
 
 #+begin_src emacs-lisp
   (custom-set-faces '(pulse-highlight-start-face ((t (:background "CadetBlue2")))))
 #+end_src
 
 ** Enable all commands
 By default, Emacs disables some commands.
 I want to have these enabled so I don't get a prompt whenever I try to use a disabled command.
 
 #+begin_src emacs-lisp
   (setq disabled-command-function nil)
 #+end_src
 ** More extensive apropos
 #+begin_src emacs-lisp

 #+end_src
 ** Enable recursive minibuffers
 #+begin_src emacs-lisp
   (setq enable-recursive-minibuffers t
         minibuffer-depth-indicate-mode t)
 #+end_src
 ** View webp and other formats
 Emacs handles common image formats internally, but for stuff like webp, you need an external converter:
 
 #+begin_src emacs-lisp
   (setq image-use-external-converter t)
 #+end_src
 
 You also need imagemagick installed.

 *** Todo & custom agenda views
 Todo keywords based on the GTD system (pipe separates incomplete from complete).
 Apart from the logging-on-done configured [[*Logging][below]], I also want to log a note & timestamp when I start waiting on something.

 +I decided that projects will not be TODO items, but their progress will be tracked with a progress cookie ([x/y]). This function converts an item to a project: it adds a PROJECT tag, sets the progress indicator to count all checkboxes in sub-items (only TODO items), and removes any existing TODO keywords. Finally, PROJECT tags shouldn't be inherited (i.e. subtasks shouldn't be marked as projects).+
 In the end, I want NEXT items that are part of a project to be shown as such (so inherit that PROJECT tag), but projects themselves will have a PROJ todo keyword.
 This function converts an item to a project.

 Define a function to skip items if they're part of a project (i.e. one of their parents has a "PROJECT" tag).
 +The problem is, the "PROJECT" tag isn't inherited. So, we temporarily disable excluding from inheritance, just for the ~org-get-tags~ call. Then check if "PROJECT" is one of the tags.+ That tag is now inherited.

 *** Automatically mark next project item as NEXT

 *** Logging for tasks
 I want to log into the LOGBOOK drawer (useful when I want to take quick notes):
 
 #+begin_src emacs-lisp
   (setq org-log-into-drawer "LOGBOOK")
 #+end_src
 
 I also want to log when I finish a task (useful for archiving).
 Furthermore, when I'm done, I want to add a note (any important
 workarounds/tips). And when I reschedule, I want to know the reason.
 I can disable logging on state change for a specific task by adding ~:LOGGING: nil~ to the ~:PROPERTIES:~ drawer.
 
 #+begin_src emacs-lisp
   (setq org-log-done 'time
         org-log-reschedule 'note)
 #+end_src
 
 I want to hide drawers on startup. This variable has options:
 - 'overview': Top-level headlines only.
 - 'content': All headlines.
 - 'showall': No folding on any entry.
 - 'show2levels: Headline levels 1-2.
 - 'show3levels: Headline levels 1-3.
 - 'show4levels: Headline levels 1-4.
 - 'show5levels: Headline levels 1-5.
 - 'showeverything: Show even drawer contents.
 
 #+begin_src emacs-lisp
   (setq org-startup-folded 'content)
 #+end_src
 
 *** Task ordering
 Some tasks should be ordered, i.e. they should be done in steps.
 Those have the ~:ORDERED: t~ setting in ~:PROPERTIES:~, and it should be enforced:
 
 #+begin_src emacs-lisp
   (setq org-enforce-todo-dependencies t)
 #+end_src
 
 Furthermore, tasks that are ordered and can't be done yet because of previous steps should be dimmed in the agenda:
 
 #+begin_src emacs-lisp
   (setq org-agenda-dim-blocked-tasks t)
 #+end_src
 
 I might also want to set ~org-enforce-todo-checkbox-dependencies~, but not convinced on that one yet.
 
 *** Time tracking & effort
 Time tracking should be done in its own drawer:
 
 #+begin_src emacs-lisp
   (setq org-clock-into-drawer "CLOCK")
 #+end_src
 
 And to customize how clock tables work:
 
 #+begin_src emacs-lisp
   (setq org-clocktable-defaults '(:lang "en" :scope agenda-with-archives  :wstart 1 :mstart 1 :compact t :maxlevel nil))
   (setq org-agenda-clockreport-parameter-plist '(:link t :maxlevel nil))
 #+end_src
 
 I want to set effort in hours:minutes:
 
 #+begin_src emacs-lisp
   (add-to-list 'org-global-properties '("Effort_ALL" . "0:05 0:10 0:15 0:20 0:30 0:45 1:00 1:30 2:00 4:00 6:00 8:00"))
 #+end_src
 
 I want column view to look like this:

 |--------------+-----------+------+---------------------+--------------------------------|
 | todo keyword | task name | tags | sum of clock        | sum of estimated time          |

 *** Priorities: how important something is
 I usually have a lot of 'next' actions, so I prefer 4 priority levels instead of the default 3: A (urgent, ASAP), B (important),  C (if you have nothing else, do this), D (do in free time):
 
 #+begin_src emacs-lisp
   (setq org-priority-highest ?A
         org-priority-lowest ?D
         org-priority-default ?C)
 #+end_src
 
 Faces for priorities in agenda:
 
 #+begin_src emacs-lisp
   (setq org-priority-faces `((?A . (:foreground ,(face-foreground 'error)))
                              (?B . (:foreground ,(face-foreground 'org-todo)))
                              (?C . (:foreground ,(face-foreground 'font-lock-constant-face) :weight semi-light))
                              (?D . (:foreground ,(face-foreground 'font-lock-string-face) :slant italic :weight light))))
 #+end_src
 
 And to be able to bulk-set priorities in agenda:
 
 #+begin_src emacs-lisp
   (setq org-agenda-bulk-custom-functions '((?P (lambda nil (org-agenda-priority 'set)))))
 #+end_src

 *** org publishing
 I decided, after trying many different things, to settle on org-publish.
 
 #+begin_src emacs-lisp
   (defconst za/org-roam-top-name "Top" "The name of the top-level Org-roam node.")
   (defun za/org-roam-sitemap-function (title list)
     "Customized function to generate sitemap for org-roam, almost the same as `org-publish-sitemap-default`."
     (concat "#+TITLE: " title "\n\n"
             (format "[[file:%s][%s]]\n\n"
                     (file-name-nondirectory (org-roam-node-file
                                              (org-roam-node-from-title-or-alias za/org-roam-top-name)))
                     "Click here for entrypoint.")))
   ;; (org-list-to-org list)))  <-- this is taken care of by Zola
 
 #+end_src
 
 To make this work with Zola, I need to export Github-flavored markdown (fenced code blocks with language):
 
 #+begin_src emacs-lisp
   (require 'ox-publish)
   (require 'ox-md)
 
   (use-package ox-gfm
     :init
     (with-eval-after-load 'org (require 'ox-gfm)))
 #+end_src
 
 First difficulty: Zola needs front matter with ~+++...+++~.
 The default Markdown backend doesn't provide that, so need to customize it by advising the default ~org-md-template~.
 
 #+begin_src emacs-lisp
   (defun za/org-md-template-zola (contents info)
     "Markdown template compatible with Zola (generates the necessary front matter from CONTENTS and INFO)."
     (let ((title (org-md-plain-text (org-element-interpret-data (plist-get info :title)) info)))
       (concat "+++\n"
               (format "title = \"%s\"\n" (string-replace "\"" "'" title))
 
               ;; If the note contains a math org-roam tag
               (when (member "math" (plist-get info :filetags))
                 "template = \"page-math.html\"\n")
 
               "+++\n"
               (format "# %s\n" title)
               contents)))
 #+end_src
 
 Second difficulty: links need to be reformatted and changed for static data (like images).
 This function filters the return value of ~org-md-link~.
 
 #+begin_src emacs-lisp
   (defun za/org-md-link-zola (linkstr)
     "A filter function for the return value of
           `org-md-link` (LINKSTR) to generate a link compatible with Zola."
     (cond ((string-match-p (rx ".md") linkstr)
            (string-replace "](" "](@/org-roam/" linkstr))
           ((string-match-p (rx "](" (? (* alnum) "://") "/") linkstr)
            (replace-regexp-in-string (rx "](" (? (* alnum) "://") "/" (* any) "/org-roam/data") "](/org-roam-data" linkstr))
           (t linkstr)))
 #+end_src
 
 A wrapper to set the right image link:
 
 #+begin_src emacs-lisp
   (defun za/org-html--format-image (args)
     "Modify source image link to work with my Org roam setup"
     (let ((source (nth 0 args))
           (_attributes (nth 1 args))
           (_info (nth 2 args)))
       (list (replace-regexp-in-string (rx bos "data/") "/org-roam-data/" source)
             _attributes
             _info)))
 #+end_src
 
 And here's the custom publish function that adds/removes the necessary advice:
 
 #+begin_src emacs-lisp
   (defun za/org-gfm-publish-to-gfm-zola (plist filename pub-dir)
     "Run `org-gfm-publish-to-gfm`, advising the necessary

 *** org-caldav
 This lets me sync my Org agenda to my CalDAV server.
 The main reason is because Orgzly doesn't have a calendar view and can't (yet) search for events on a specific day, so if someone asks "are you free on that day", it's a bit hard for me to answer if I don't have my computer with me.
 This way, I can just check my calendar.

 An alternative to the built-in Emacs help that provides much more contextual information.
 I use counsel, so I use the keybindings in [[*counsel + ivy + swiper]].
 I just augment the functions counsel uses.
 Also, counsel doesn't provide some keybindings that I can get from helpful.

 In a new version of use-package, I can use the :vc keyword, so check for when that's available.
