This configuration of Emacs is highly opinionated.

Basics

My identity. Used in a handful of places in Emacs to pre-populate authorship and such.

(setq user-full-name "Colin Powell"
      user-mail-address "colin@unbl.ink")

From a friend at Discord

(setq ivy-read-action-function #'ivy-hydra-read-action)

User interface

Fonts and themes

I change my default theme almost as often as the weather. I tend to revert back to Doom One most of the time, but I like the Kaolin themes, as well as Nimbus for it's retro charm. Nimbus just doesn't look great when I'm tired though.

(setq doom-theme 'doom-homage-black
      doom-font (font-spec :family "Iosevka" :size 14 :weight 'regular)
      doom-big-font (font-spec :family "Iosevka" :size 18)
      doom-variable-pitch-font (font-spec :family "Overpass" :size 16))

Borders

Barring the unfortunate end of X11 development and my eventual transition to Wayland and sway, you can pry i3wm from my cold, dead hands. One problem, however is that when you're trying your best to rice up i3, Emacs needs a padded border.

;; Applies to current frame
(set-frame-parameter nil 'internal-border-width 10) ; applies to the current frame
;; If we create new frames (via emacsclient) this will do the trick
(add-to-list 'default-frame-alist '(internal-border-width . 10))

Fringe

(nyan-mode) ;; progress in the form of a rainbow cat.
(add-hook 'after-init-hook #'global-emojify-mode) ;; emojis?!
(add-hook 'prog-mode-hook #'goto-address-mode)  ;; linify links!

Keybindings

        :desc "Search all the things"   "g" #'deadgrep))

Weather

Wttrin is a pretty funny way to check weather. I like that you can copy and paste fun a ASCII representations of the day's weather. It's not terribly accurate though.

(setq wttrin-default-cities '("Castine, ME" "San Francisco" "Thessaloniki"))
(setq wttrin-default-accept-language '("Accept-Language" . "en-US"))

(map!
 (:leader
   (:prefix "o"
    :desc "(W)eather" "W" #'wttrin)))

Music

Right now, just make sure I can connect to my local Mopidy server via MPDel.

(setq libmpdel-hostname "mpd.unbl.ink")

(defun mpdel-playlist-play ()
  "Start playing the song at point."
  (interactive)
  (if (derived-mode-p 'mpdel-playlist-current-playlist-mode)
      (libmpdel-play-song (navigel-entity-at-point))
    (mpdel-core-insert-current-playlist)))

(map! :leader
      (:prefix "-"
        :desc "MPD Open playlist"       "-" #'mpdel-playlist-open
        :desc "MPD Remove at point"     "d" #'mpdel-playlist-delete
        :desc "MPD Start at point"      "s" #'mpdel-playlist-play
        :desc "MPD Next track"          "n" #'libmpdel-playback-next
        :desc "MPD Previous track"      "p" #'libmpdel-playback-previous))

RSS

Here we’re going to use TinyTinyRSS as a backend store for our RSS feeds.

(setq elfeed-protocol-ttrss-maxsize 100) ;; bigger than 200 is invalid
(setq elfeed-feeds '("ttrss+https://powellc:hT7nPKAHa^fYwXZ*@reader.unbl.ink"))

(setq elfeed-log-level 'debug)
(elfeed-protocol-enable)

;; Schedule feed update for every 15 minutes
(run-at-time "30 min" nil 'elfeed-update)

Then wel’ll setup some nice defaults and font settings for viewing feeds in Elfeed.

(setq elfeed-search-filter "@2-days-ago +unread")
(defun elfeed-search-format-date (date)
  (format-time-string "%Y-%m-%d %H:%M" (seconds-to-time date)))

; Serif font in Elfeed
(add-hook! 'elfeed-mode-hook 'variable-pitch-mode)
(add-hook! 'elfeed-show-mode-hook (text-scale-set 1.2))

Formatting

Here we define the opposite function to fill-paragraph and then map it to Meta-z, which helps when undoing fill paragraph moves.

(defun unfill-paragraph ()
  "Takes a multi-line paragraph and makes it into a single line of text."
  (interactive)
  (let ((fill-column (point-max)))
    (fill-paragraph nil)))

(define-key global-map "\M-z" 'unfill-paragraph)

PlantUML is pretty fantastic. This enables a mode for editing plantuml files in Emacs.

;; PlantUML is awesome for quick diagrams
(add-to-list 'auto-mode-alist '("\\.plantuml\\'" . plantuml-mode))

Handy clock to look up what timezone my co-workers are in!

;; Timezone location strings at http://worldtime.io
(setq display-time-world-list '(("America/Los_Angeles" "San Francisco")
                                ("America/Tegucigalpa" "Tegucigalpa")
                                ("America/New_York" "New York")
                                ("Europe/London" "London")
                                ("Europe/Warsaw" "Warsaw")
                                ("Europe/Kiev" "Lviv")))

Vale linter, a more up to date proselint!

How I went about installing Vale

(flycheck-define-checker vale
  "A checker for prose"
  :command ("vale" "--output" "line"
            source)
  :standard-input nil
  :error-patterns
  ((error line-start (file-name) ":" line ":" column ":" (id (one-or-more (not (any ":")))) ":" (message) line-end))
  :modes (markdown-mode org-mode text-mode)
  )
(add-to-list 'flycheck-checkers 'vale 'append)

(setq +format-on-save-enabled-modes
      '(not emacs-lisp-mode  ; elisp's mechanisms are good enough
            sql-mode         ; sqlformat is currently broken
            tex-mode         ; latexindent is broken
            org-mode
            latex-mode))

Org-mode

Basic configuration

A handful of mods here clean up org mode. Line numbers don’t mean much when you’re folding and unfolding all the time. I also really enjoy the typography of a serif font when I’m writing a lot of words.

(add-hook 'org-mode-hook #'doom-disable-line-numbers-h)

(after! org
  (setq org-directory (expand-file-name "~/var/org/")
        org-agenda-files (file-expand-wildcards "~/var/org/2020-*")
        org-pretty-entities t
        org-agenda-dim-blocked-tasks nil
        org-log-done 'time
        org-hide-emphasis-markers t
        org-fontify-whole-heading-line t
        org-fontify-done-headline t
        org-fontify-quote-and-verse-blocks t
        org-ellipsis "…"
        org-image-actual-width '(600)
        org-protocol-default-template-key "l"
        org-capture-templates
        '(("i" "Send to inbox" entry (file "~/var/org/inbox.org")
           "* TODO %?\n")
          ("l" "Link" entry (file "~/var/org/inbox.org")
           "* TODO %a\n %?\n %i"))
        org-todo-keywords
        '((sequence "TODO(t)" "NEXT(n)" "MAYBE(m)" "|" "DONE(d)" "WONTDO(w)"))
        org-modules '(ol-eshell
                      ol-notmuch
                      ob-eval
                      ob-exp
                      ob-http
                      org-id)))

;; Don’t display git gutter in org mode
;; With tree folding, it's pretty much useless
(after! git-gutter
  (setq git-gutter:disabled-modes '(org-mode image-mode)))

;; Refiling
(setq org-refile-targets '(("~/var/org/inbox.org" :maxlevel . 9)))
(setq org-outline-path-complete-in-steps nil)         ; Refile in a single go
(setq org-refile-use-outline-path t)                  ; Show full paths for refiling

Key bindings

I add only two custom mappings to the default org mode maps, a shortcut to my Inbox file and a quick way to save all open org mode files.

(setq +inbox-file "~/var/org/inbox.org")
(defun +open-inbox-file ()
  (interactive)
  "Opens the inbox file"
  (find-file +inbox-file))

(map!
 :leader
   :desc "Open inbox" "I" #'+open-inbox-file
   :desc "Save all org buffers" "A" #'org-save-all-org-buffers)

Agenda configuration

(setq org-agenda-span 3
      org-agenda-start-day "1d")
(defun +show-agenda ()
  (interactive)
  (delete-other-windows)
  (with-popup-rules! nil
    (org-agenda-list)
    (calendar))
  (other-window 1)
  (split-window-vertically)
  (other-window 1)
  (find-file +todo-file))

Org-roam

I am absolutely in love with Org-roam. Everything about it makes taking notes easier. I just need to level up with Zettels and web publishing of my notes.

(setq org-roam-directory "~/var/org/")
(setq org-roam-dailies-directory "")

(setq org-roam-dailies-capture-templates
      '(("d" "default" entry
         #'org-roam-capture--get-point
         "* %?"
         :file-name "%<%Y-%m-%d>"
         :head "#+title: %<%Y-%m-%d>\n\n")))

/

Org-fc

Trying a new space-repetition framework.

(setq org-fc-directories "~/var/org/")
(require 'org-fc-hydra)

Novel

Reading novels in Emacs, how novel!

(require 'justify-kp)
;(setq nov-text-width t)
(setq nov-text-width 100)

(defun my-nov-window-configuration-change-hook ()
  (my-nov-post-html-render-hook)
  (remove-hook 'window-configuration-change-hook
               'my-nov-window-configuration-change-hook
               t))

(defun my-nov-post-html-render-hook ()
  (if (get-buffer-window)
      (let ((max-width (pj-line-width))
            buffer-read-only)
        (save-excursion
          (goto-char (point-min))
          (while (not (eobp))
            (when (not (looking-at "^[[:space:]]*$"))
              (goto-char (line-end-position))
              (when (> (shr-pixel-column) max-width)
                (goto-char (line-beginning-position))
                (pj-justify)))
            (forward-line 1))))
    (add-hook 'window-configuration-change-hook
              'my-nov-window-configuration-change-hook
              nil t)))
(add-hook 'nov-post-html-render-hook 'my-nov-post-html-render-hook)

(defun my-nov-font-setup ()
  (face-remap-add-relative 'variable-pitch :family "Noto Serif Regular"
                                           :height 1.0
                                           :size 16))
(add-hook 'nov-mode-hook 'my-nov-font-setup)
(add-to-list 'auto-mode-alist '("\\.epub\\'" . nov-mode))

;(add-hook 'nov-mode-hook 'variable-pitch-mode)

Mail

Basics

I use notmuch to read and write email from within Emacs.

Here, we'll plan to use w3m to parse HTML email. You do have to make sure w3m is somehow installed on your machine.

(setq mm-text-html-renderer 'w3m)
(setq w3m-fill-column 88)

A few nice to haves for messages. First we kill email message buffers when they are closed. Then we set our auto save directory and generic message directory.

(setq message-kill-buffer-on-exit t)
(setq message-auto-save-directory "~/Mail/colin@unbl.ink/Drafts/")
(setq message-directory "~/Mail/colin@unbl.ink/")

We'll use `msmtp` to send our email. Again, make sure this is installed.

;; sendmail-program "/usr/local/bin/msmtpq" <--- this doesn't work as advertised right now
(setq send-mail-function 'sendmail-send-it
      sendmail-program "/usr/local/bin/msmtp"
      mail-specify-envelope-from t
      message-sendmail-f-is-evil t
      message-sendmail-envelope-from 'header
      message-sendmail-extra-arguments '("--read-envelope-from")
      mail-envelope-from 'header)

Set our custom saved searches so we can conveniently jump to different mail views.

(setq notmuch-saved-searches '((:name "inbox" :query "tag:inbox" :key "i")
                               (:name "unread" :query "tag:inbox and tag:unread" :key "u")
                               (:name "jira" :query "tag:jira and date:yesterday..today" :key "j")
                               (:name "github" :query "tag:github and date:yesterday..today" :key "g")))

We want to make sure notmuch opens in a full window

(after! notmuch
  (set-popup-rule! "^\\*notmuch*" :ignore t)
  )

Keybindings

(map! :leader
   (:prefix "e"
     :desc "(s)end queued mail" "s" #'smtpmail-send-queued-mail

Eshell

Handful of fun aliases to make working in Eshell almost like a real shell :smile:

   "gl"    "(call-interactively 'magit-log-current)"
   "gs"    "magit-status"
   "gc"    "magit-commit"))

Coding

LSP doesn't like big projects and I can't blame it. This forces it to index huge projects without warning us everytime.

(after! lsp
  (setq lsp-file-watch-threshold nil))

Mastodon

There's gotta be a way to get the token out of password-store for this.

(setq mastodon-instance-url "https://mastodon.technology")

(map! :leader
      (:prefix "="
        :desc "Open mastodon"                "=" #'mastodon
