Welcome to my configuration! I hope you enjoy your time here :) It's not all very well documented, but I have done my best to split everything into a logical order. Perhaps in 10 years I will still be using it, but who knows.

Setting Basics

Packages

;; -*- no-byte-compile: t; -*-

Set name, org-roam-directory, etc.

Some basic settings for Emacs

(setq tab-always-indent t)

(setq user-full-name "Judah Sotomayor"
      user-mail-address "")

(package! noCtrlC
  :recipe (:host nil :type git :repo "https://git.freedomland.xyz/judahsotomayor/noctrlc"))

Theme and Font

Set the theme. Use something dark I also prefer relative line numbers because of evil mode Relative line numbers don't seem to work, because of folding in Org-mode.

(setq doom-theme 'doom-xcode)
(setq doom-font (font-spec :family "Hack Nerd Font Mono" :size 16 :weight 'medium))

(setq auto-save-default nil) ;I don't like autosaving. Let me do it myself.

Doom splash screen

I really don't like the widgets, and I think it takes longer to load so I get rid of them

(remove-hook '+doom-dashboard-functions #'doom-dashboard-widget-shortmenu)
(remove-hook '+doom-dashboard-functions #'doom-dashboard-widget-footer)

Set a sweet splash image

(setq fancy-splash-image (concat doom-private-dir "emacs.png"))

Evil configuration

I want a non-ESC way to get back to normal mode:

(map! :desc "Switch to normal mode" :i "C-c" #'evil-normal-state)
(after! org-mode (map! :desc "Delete previous character in insert mode" :i "C-h" #'evil-delete-backward-char))
(map! :desc "Increment number below or after cursor" :n "C-a" #'evil-numbers/inc-at-pt)
(map! :desc "Decrement number below or after cursor" :n "C-x" #'evil-numbers/dec-at-pt)
(map! :n "g j" #'evil-next-visual-line)
(map! :n "g k" #'evil-previous-visual-line)

Terminal setup

I like to just use bash:

(defun bash nil
  "Lauch term with /bin/bash"
  (interactive)
  (term "/bin/bash"))

(defun dash nil
  "Lauch term with /bin/dash"
  (interactive)
  (term "/bin/dash"))

(defun zsh nil
  "Lauch term with /bin/zsh"
  (interactive)
  (term "/bin/zsh"))

zsh

Shell mappings

(map! :leader (:prefix ("k" . "shell")

      :desc "Start a bash shell"
      :n "b" #'bash

      :desc "Start a dash shell"
      :n "d" #'dash

      :desc "Start a zsh shell"
      :n "z" #'zsh

      :desc "Start an elisp repl"
      :n "e" #'+emacs-lisp/open-repl

      :desc "Start a python repl"
      :n "j" #'+python/open-repl))

,#+RESULTS:

I don't like the modeline in the terminal. ,#+begin_src emacs-lisp (add-hook 'term-mode-hook 'hide-mode-line-mode)

#+end_src

Sage-math

(use-package! sage-shell-mode
  :defer)

;; Ob-sagemath supports only evaluating with a session.
(setq org-babel-default-header-args:sage '((:session . t)
                                           (:results . "output")))

;; C-c c for asynchronous evaluating (only for SageMath code blocks).
(with-eval-after-load "org"
  (define-key org-mode-map (kbd "C-c c") 'ob-sagemath-execute-async))

I like to have a shortcut for calc as well, for simpler calculations

(map! :leader
      :desc "The Emacs Calculator"
      "C" #'calc)

Beancount

FavaGTK   outdated

I want to launch favagtk more easily. Let's do that here:

(defun fava ()
  (interactive)
  (async-shell-command "flatpak run org.gnome.gitlab.johannesjh.favagtk"))
(map! :leader
 :desc "Start favagtk"
 "r b" #'fava)

Useful Functions

Get the date from the shell

I want to grab the current date and put it in the buffer. Because I sometimes use Fish or another shell, it's good to make sure bash is running the command using the

`-c`

flag.

 (defun insert-current-date () (interactive)
    (insert (string-trim (shell-command-to-string "date '+%Y-%m-%d'"))))

 (defun insert-current-date-alt () (interactive)
    (insert (string-trim (shell-command-to-string "date '+%B %d, %Y'"))))

(map! :leader (:prefix ("i" . "insert") (:prefix ("d" . "date")
      :desc "ISO 8601 (%Y-%m-%d)"
      "i" #'insert-current-date

      :desc "Month Day, Year (%B %d, %Y)"
      "m" #'insert-current-date-alt)))

insert-current-date-alt

Convert regex strings to rx

(package! xr)

(use-package! xr)

Creating Diagrams and graphs

TODO set default values using org-babel's features for that.

Securing Sensitive Files

Age.el

(package! age)

Config

(use-package! age
  :ensure t
  :demand t
  :custom
  (age-program "age")
  (age-default-identity "~/.age/personal")
  (age-default-recipient "~/.age/personal.pub")
  :config
  (age-file-enable))

Preprocessor

This preprocessor script allows me to use Ripgrep with Age to filter agenda files. You can see the configuration for that in this section.

#!/usr/bin/env zsh

case "$1" in
*.age)
    # The -s flag ensures that the file is non-empty.
    if [ -s "$1" ]; then
        exec /usr/bin/age --decrypt -i ~/.age/personal $1
    else
        exec cat
    fi
    ;;
*)
    ;;
esac

Org-mode security settings

These mostly concern limiting evaluation of code-blocks without confirmation. The final two lines concern local variables, which may try to evaluate code.

Emacs has better default values now, so it will ask to evaluate local variables.

(setq org-confirm-babel-evaluate t)
(setq org-link-shell-confirm-function 'yes-or-no-p)
(setq org-link-elisp-confirm-function 'yes-or-no-p)
(setq enable-local-variables t)
(setq enable-local-eval 'maybe)

maybe

    (setq templates/post-capture-props "#+date: [%<%Y-%m-%d %a>]\n#+lastmod:\n#+categories[]:\n#+tags[]:\n#+images[]: ")
    (setq templates/post-capture-title "#+TITLE: ${title}\n")
    (setq templates/post-capture-template (concat templates/post-capture-title templates/post-capture-props))

Org-mode for a great todo list

Making the Agenda features more efficient

Using ripgrep we can automatically narrow org-agenda files.

Finding Files with Ripgrep

This piece of code will allow us to capture all the agenda files using the preprocessor we wrote here

rg --type-add 'aorg:*.org.age' \
    -torg -taorg \
    --pre ~/age-preprocessor.zsh --pre-glob '*.age' -l TODO /home/user/org

Now, of course, this code is not useful as it is–after all, we can't tangle a .sh script into /judahsotomayor/doom/src/commit/941712eb6f5f015a9544d8304212619cd6f3c57b/config.el.

Adding results to agenda files

The rubber hits the road here. I'll call that shell command to set the agenda files correctly.

(defun set-org-agenda-files-ripgrep ()
    (setq org-agenda-files (split-string (shell-command-to-string "rg --type-add \'aorg:*.org.age\' -torg -taorg --pre ~/age-preprocessor.zsh --pre-glob \'*.age\' -l TODO /home/user/org ")))
    (setq org-agenda-files (remove "/home/user/org/archive.sec.org.age" org-agenda-files)))

set-org-agenda-files-ripgrep

And then we want to call this before building the agenda:

(add-hook 'org-agenda-mode-hook 'set-org-agenda-files-ripgrep)

Filtering the agenda

I don't want scheduled items to duplicate if the deadline is up.

(after! org
  (setq org-agenda-skip-scheduled-if-deadline-is-shown t))
;(setq org-agenda-start-day "-8d")
;(setq org-agenda-span 9)
;(setq org-agenda-todo-ignore-deadlines 'far)
;(setq org-agenda-tags-todo-honor-ignore-options t))

t

Basic settings

(setq org-log-done 'time)
(after! org
  (setq org-log-done 'time)
  (setq org-archive-location "~/10-19-personal-projects/11-zettelkasten/archive.sec.org.age")
  (setq org-hide-emphasis-markers nil))
(setq org-directory "~/10-19-personal-projects/11-zettelkasten/")
(setq org-roam-directory org-directory)

~/org/

Keymap

(map!
 :map org-agenda-keymap
 "j" #'evil-next-line
 "k" #'evil-previous-line)
(map!
 :map org-super-agenda-header-map
 "j" #'evil-next-line
 "k" #'evil-previous-line)

Appearances

Images Preferences

We want to show images when loading a file, and also after evaluating code blocks.

(setq org-startup-with-inline-images t)

;; Show images after evaluating code blocks.
(add-hook 'org-babel-after-execute-hook 'org-display-inline-images)

Org-super-agenda

Super-agenda allows many nice configurations to the agenda buffer.

(package! org-super-agenda)

Is it working now? It sure seems to be, so IDK what was up with it earlier.

(use-package! org-super-agenda
  :after org-roam
  :config (org-super-agenda-mode))

Configure the Super Agenda to neatly organize everything.

(setq org-super-agenda-groups
       '(;; Each group has an implicit boolean OR operator between its selectors.

         (:name "Calendar"
                 :and (:todo nil :not (:scheduled (before "2024-03-17")) :not (:deadline (before "2024-03-17")))
                 :order 10)

         (:name "Today"  ; Optionally specify section name
          :time-grid t  ; Items that appear on the time grid
          :todo "TODAY")  ; Items that have this TODO keyword

         (:name "Important"
          ;; Single arguments given alone

          :priority<= "A")
         (:name "Active Projects"
          :and (:todo "PROJ"
                :not (:scheduled (after "2024-03-17"))
                :deadline (after "2024-03-17")))

         (:name "School"
          :tag "school" )

         ;; Set order of multiple groups at once
         (:order-multi (2 (:name "Shopping in town"
                           ;; Boolean AND group matches items that match all subgroups
                           :and (:tag "shopping" :tag "@town"))
                          (:name "Food-related"
                           ;; Multiple args given in list with implicit OR
                           :tag ("food" "dinner"))
                          (:name "Habits"

                           ;; Regexps match case-insensitively on the entire entry
                           :and (:regexp ("space" "NASA")
                                 ;; Boolean NOT also has implicit OR between selectors
                                 :not (:regexp "moon" :tag "planet")))))
         ;; Groups supply their own section names when none are given

         (:todo ("SOMEDAY" "TO-READ" "CHECK" "TO-WATCH" "WATCHING")
          ;; Show this group at the end of the agenda (since it has the
          ;; highest number). If you specified this group last, items
          ;; with these todo keywords that e.g. have priority A would be
          ;; displayed in that group instead, because items are grouped
          ;; out in the order the groups are listed.
          :order 9)
         (:priority<= "B"
          ;; Show this section after "Today" and "Important", because
          ;; their order is unspecified, defaulting to 0. Sections
          ;; are displayed lowest-number-first.
          :order 1)))

org-edna

(package! org-edna)

Edna allows better dependency handling for todos and the like.

(use-package! org-edna)

Anki editing in org-mode

Anki editor is a good one for large cards that need high complexity.

(package! anki-editor)

inline-anki

Inline anki is far better for small cards, and where it is best to maintain a single source of truth.

(package! asyncloop)
(package! inline-aki
         :recipe (:host github :repo "meedstrom/inline-anki"))

(setq inline-anki-note-type "Katex and Markdown Cloze")
(setq inline-anki-use-tags t)

Inline Anki symbol

By default, Inline-anki uses underscore to specify the card type. This is okay, but I'd rather find something that isn't already used.

(add-to-list 'org-emphasis-alist '("." nil))
(setq inline-anki-emphasis-type "_")

Automatic Citations with citar and org-cite

Citar is a sweet little package for managing citations. We want a general bibliography file, a styles directory, and a default set of styles.

Citar setup

First of all, we must configure citar.

(package! citar-org-roam)

(use-package! citar
  :custom
  (citar-bibliography "~/10-19-personal-projects/11-zettelkasten/references.bib")
  (citar-file-note-extensions '(".org"))
  (org-cite-global-bibliography '("~/10-19-personal-projects/11-zettelkasten/references.bib"))

  (org-cite-csl-styles-dir
   (expand-file-name "~/Zotero/styles/"))
  (org-cite-export-processors
   '((t . (csl "apa.csl")) ))

  :hook
  (LaTeX-mode . citar-capf-setup)
  (org-mode . citar-capf-setup))

Icons for some prettification

    (setq citar-indicator-files-icons
      (citar-indicator-create
       :symbol (nerd-icons-faicon
                "nf-fa-file_o"
                :face 'nerd-icons-green
                :v-adjust -0.1)
       :function #'citar-has-files
       :padding "  " ; need this because the default padding is too low for these icons
       :tag "has:files"))

Zettelkasten environment with org-roam

Org-roam enables features essential to a Zettelkasten such as inter-ID linking.

(use-package! org-roam
  :after md-roam)

I use several capture templates to make it easy to get notes into my various sections. I only use Markdown in the team wiki, so I have it set to that. I also have a capture template form my /judahsotomayor/doom/src/commit/941712eb6f5f015a9544d8304212619cd6f3c57b/Website

Keybinds

Org-roam has many commands, of which I have bound the most important below. This entails creating a local leader. I use r for this purpose. It is close and goes well with roam.

                :desc "Search for a node in org-roam files"
                "f" #'org-roam-node-find

                :desc "Insert the link to a node from org-roam"
                "i" #'org-roam-node-insert

                :desc "Rescan org-roam files and add new nodes to database"

• Gantt diagrams

There's other kinds too. The package on ELPA is perfect. Needs no config, fits right in with Babel.
