I've come to prefer using a light theme during the day, and a dark theme at night. Using a dark theme with daylight leads to cranking up the screen brightness, which hurts my eyes more than using the light theme.

Set my light and dark themes:

(setq my/light-theme doom-theme
      my/dark-theme 'doom-one)

Function to toggle between the two easily:

(defun my/toggle-dark-theme ()
  (interactive)
  (if (eq my/dark-theme doom-theme)
      (load-theme my/light-theme t)
    (load-theme my/dark-theme t)))

Bind this to SPC t d:

(map! :leader
      (:prefix-map ("t" . "toggle")
       :desc "Dark theme" "d" #'my/toggle-dark-theme))

Font

Doom exposes five (optional) variables for controlling fonts in Doom. Here are the three important ones:

doom-font
doom-variable-pitch-font
doom-big-font – used for doom-big-font-mode; use this for presentations or streaming.

They all accept either a font-spec, font string (Input Mono-12), or xlfd font string. You generally only need these two:

(setq doom-font
      (font-spec :family "Input Mono Narrow" :size 12 :style 'regular))

Line numbers

Possible values of display-line-numbers-type are nil, t, and 'relative.

(setq display-line-numbers-type nil)

Battery indicator

I'm on a laptop, so let's display my battery in the modeline:

(display-battery-mode 1)

Programming

Smart parens

Disable smart parens because half of the time it doesn't do what I want:

(remove-hook 'doom-first-buffer-hook #'smartparens-global-mode)

Rust

By default rustic-mode uses rls, I want to use rust-analyzer instead.

(setq rustic-lsp-server 'rust-analyzer)

I don't want to enable format-on-save globally in Doom, but having it in rust is nice.

(after! rustic
  (setq rustic-format-trigger 'nil))

rustfmt limits lines to 100 characters, let's display it correctly.

(add-hook! rustic-mode
  (set-fill-column 100))

C/C++

Default style

Setup the default format for C/C++ editing.

(add-hook! (c-mode c++-mode)
  (setq c-default-style "gnu")
  (setq c-basic-offset 2))

Flycheck

Flycheck never works well for C / C++ without configuration or a CMake build system. Let's disable it.

(after! flycheck
  (setq flycheck-global-modes '(not c-mode c++-mode)))

Org mode

Appearance

Disable fancy stars

(remove-hook 'org-mode-hook #'org-superstar-mode)

Don't hide leading stars

Currently doesn't work due to hlissner/doom-emacs#3076

(after! org
  (setq org-hide-leading-stars nil
        org-startup-indented nil
        org-adapt-indentation nil))

Fancier ellipsis indicator

(setq org-ellipsis " ▼ ")

Agenda setup

Default task keywords

Here are the keywords I'm using to track task progress. I'm also making use of some automatic state changes.

keyword	meaning
`TODO`	Self explanatory
`DONE`	This task is finished, no longer displayed in the agenda
`CANCELLED`	This task isn't finished but is no longer relevant

(after! org
  (setq org-todo-keywords
        '((sequence
           "TODO(t)"
           "|"
           "DONE(d!)"
           "CANCELLED(c@/!)")
          (sequence
           "[ ](T)"
           "|"
           "[X](D)"))))

Org capture setup

Of course I also need to setup capture templates:

The first one just prompts me for a new task to add to my inbox, I can then refile them where I want later.

The second one exists because I like to keep a separate list of articles / papers / books to read.

(after! org
  (setq org-capture-templates
        '(("t" "New entry" entry (file "inbox.org")
           "* TODO %?")
          ("T" "Task" entry (file "tasks.org")
           "* TODO %?")
          ("r" "Reading" entry (file "reading.org")
           "* TODO %x"
           :immediate-finish t)
          ("w" "Watching" entry (file "watching.org")
           "* TODO %x"
           :immediate-finish t))))

I also change the default Doom binding for #'org-capture to be SPC x instead of SPC X. Also need to rebind what was previously bound to SPC x, to SPC X.

(map! :leader
      :desc "Org Capture"           "x" #'org-capture
      :desc "Pop up scratch buffer" "X" #'doom/open-scratch-buffer)

Main agenda view

All these tasks, once captured, are then centralized in my agenda view.

I'm using multiple categories to organize tasks, depending on their triage / status (inspired by https://blog.jethro.dev/posts/org_mode_workflow_preview/).

(after! org-agenda
  (setq org-agenda-custom-commands
        '((" " "Agenda"
           ((agenda ""
                    ((org-agenda-span 'day)
                     (org-agenda-start-day nil)
                     (org-deadline-warning-days 365)))
            (todo "TODO"
                  ((org-agenda-overriding-header "Triage")
                   (org-agenda-files '("~/org/inbox.org"))))
            (todo "TODO"
                  ((org-agenda-overriding-header "School")
                   (org-agenda-files '(
                                       "~/org/image.org"
                                       "~/org/rdi.org"
                                       ))
                   (org-agenda-skip-function '(org-agenda-skip-entry-if 'deadline
                                                                        'scheduled))))
            (todo "TODO"
                  ((org-agenda-overriding-header "Assistant")
                   (org-agenda-files '("~/org/assistant.org"))
                   (org-agenda-skip-function '(org-agenda-skip-entry-if 'deadline
                                                                        'scheduled))))
            (todo "TODO"
                  ((org-agenda-overriding-header "Tasks")
                   (org-agenda-files '("~/org/tasks.org"))
                   (org-agenda-skip-function '(org-agenda-skip-entry-if 'deadline
                                                                        'scheduled))))
            (todo "TODO"
                  ((org-agenda-files '("~/org/watching.org"))
                   (org-agenda-overriding-header "To Watch")))
            (todo "TODO"
                  ((org-agenda-files '("~/org/reading.org"))
                   (org-agenda-overriding-header "To Read")))
            (todo "TODO"
                  ((org-agenda-files '("~/org/notes.org"))
                   (org-agenda-overriding-header "Note Taking")))
            (todo "TODO"
                  ((org-agenda-files '("~/org/project.org"))
                   (org-agenda-overriding-header "Personal projects")))
            )))))

I want the default agenda view to be a weekly view, with a log of what I've done during the day.

(after! org-agenda
  (setq org-agenda-span 'week)
  (setq org-agenda-start-on-weekday 1)
  (setq org-agenda-start-with-log-mode '(clock)))

I also remove the block separators in the agenda view:

(after! org-agenda
  (setq org-agenda-block-separator ""))

Habits

Let's enable the org-habit module:

(add-to-list 'org-modules 'org-habit)

Save all org buffers shortcut

By default bound to C-x C-s, rebind it to SPC m s in org-agenda-mode :

(map! :after org-agenda
      :map org-agenda-mode-map
      :localleader
      "s" #'org-save-all-org-buffers)

Org IDs

Org can link to entries using UUIDs, but we need the module to be loaded for links to work:

(add-to-list 'org-modules 'org-id)

Roam

Setup for org-roam.

Roam Directory

First, set a directory where org-roam will index things.

(setq org-roam-directory (expand-file-name "notes/" org-directory))

Graph browser

Instruct org-roam to use firefox-developer-edition to open the graph:

(setq org-roam-graph-viewer (executable-find "firefox-developer-edition"))

Roam link font face

Change link color for org-roam links, to distinguish them from standard Org links:

(after! org-roam
  (set-face-attribute 'org-roam-link nil :foreground "#FF8860"))

Roam capture template

Customize the capture templates:

the first one is the default one, I just removed the timestamp from the file title.
the second one I use to create new entries about website links, blog posts, articles… The %x in the template is replaced by the content of my X clipboard, so I just have to copy the website URL before capturing it.

(after! org-roam
  (setq org-roam-capture-templates
        '(("d" "default" plain (function org-roam-capture--get-point)
           "%?"
           :file-name "${slug}"
           :head "#+TITLE: ${title}\n"
           :unnarrowed t)
          ("i" "instant" plain (function org-roam-capture--get-point)
           "%?"
           :file-name "${slug}"
           :head "#+TITLE: ${title}\n"
           :unnarrowed t
           :immediate-finish t)
          ("w" "website" plain (function org-roam-capture--get-point)
           ""
           :file-name "websites/${slug}"
           :head "#+TITLE: ${title}\n#+ROAM_KEY: %x\n"
           :unnarrowed t)
          ("p" "paper" plain (function org-roam-capture--get-point)
           "%?"
           :file-name "papers/${slug}"
           :head "#+TITLE: ${title}\n"
           :unnarrowed t))))

Roam daily capture templates

Also setup daily captures templates, mainly used to store them in a journal/ directory instead of at the root.

(after! org-roam
  (setq org-roam-dailies-capture-templates
        '(("d" "daily" plain (function org-roam-capture--get-point)
           ""
           :immediate-finish t
           :file-name "journal/%<%Y-%m-%d>"
           :head "#+TITLE: %<%Y-%m-%d>"))))

Org Roam Server

org-roam-server provides a fancy JS interface to visualize the graph. Just needs to be loaded, along with its dependency simple-httpd.

(use-package! simple-httpd)
(use-package! org-roam-server)

Export backends

Sometimes I need to export an Org subtree to a file, which is quite easy with the org export backend. It doesn't seem to be enabled by default, so let's add it to the list:

(after! org
  (add-to-list 'org-export-backends 'org))

Doom specific

Doom replaces the default tab behavior on headings, this restores the default one. Taken from here.

(after! evil-org
  (remove-hook 'org-tab-first-hook #'+org-cycle-only-current-subtree-h))
