Introduction
Emacs outshines all other editing software in approximately the same way that the noonday sun does the stars. It is not just bigger and brighter; it simply makes everything else vanish.
– Neil Stephenson, In the Beginning was the Command Line (1998)
Hello!
This is a literate configuration for Doom Emacs.
Background; or, My Emacs Story
Given that you are currently reading an Emacs config, I will assume that you already have a moderate understanding of what Emacs is and the ideas behind its configuration system. If you do not, then this section of the official Doom Emacs documentation makes for a decent introduction.
Rather than use this space to explain Emacs, I will instead use it to chronicle my history with Emacs, how I got here, and what lessons should be taken away from this experience. Don't worry, I promise it won't be long.
In The Beginning
My first brush with Emacs was in around 2019, when I installed it for use with the proof assistant language Agda. I had vaguely heard tales about its beauty and power, but I was nowhere near comfortable enough with config files and programming in general to fully appreciate its capabilities (not to mention that I was using Windows at the time). I bounced off of it pretty quickly because… well, vanilla Emacs is just kinda terrible.
A few years later in 2022, after I had moved to the more sensible OS of Arch Linux, I discovered that my preferred text editor Atom was in the process of being discontinued and began to look for a replacement. I tried Visual Studio Code for a little while, but after some serious use I became dissatisfied with how few options there were to customize it to fit my workflow.
It was at this point that I started thinking about Emacs again. By chance, I happened to stumble upon Doom Emacs, and it turned out to be exactly what I was looking for:
- Extreme flexibility
- Robust modular configuration system
- Sensible defaults
- Extensive ecosystem
As I became more comfortable with configuration via scripting, I immersed myself into the many utilities that make up the Emacs ecosystem: org-mode, calfw, calc, mu4e. I started putting more and more time into tweaking these applications to fit my needs, my files kept getting longer and longer, and eventually I fully fell off the deep end and now we're here.
TODO Literate Programming
My first Doom Emacs config was hacked together directly from the generated example config: no comments, no organization, nothing. after! and use-package! blocks were scattered about the file without rhyme or reason, making it very difficult to remember what any particular line of code was actually doing. I was able to mitigate some of this issue by categorizing my config into multiple files, but at the end of the day it was a losing battle. The config directory was at 1200 lines of code before I decided that something needed to be done.
I was considering what to do about this problem of organizational decay when I came across Tecosaur's config and learned about org-mode's literate programming support. I had been using org-mode for several months at this point and was very comfortable with it, so utilizing it to better organize my code seemed like a good idea.
confpkg
As part of their literate config, Tecosaur implemented confpkg, an embedded Emacs Lisp library that manages multiple aspects of config tangling:
- Controlling what files each code block is tangled to
- Generating package files from templates
- Automatically detecting cross-section dependencies
- Reporting profiling information on config load times
It's an incredibly impressive utility, and I highly recommend reading the section in their config on its design. I tried to read through it myself, but I don't understand half of it; it's a bizarre mixture of exploits to hook into org-mode's tangling process, self-modifying buffer shenanigans, and abuse of various features of org-babel.
Luckily, I don't need to be able to understand code in order to do what I do best: press Ctrl+C and Ctrl+V in that order. Programming!
If you're reading the raw org file instead of the published version, the code for confpkg is below. It is mostly unchanged, aside from these tweaks:
- Prevent the code from being exported
- Reorganize to get rid of superfluous noweb references
- Change the package template to contain my information
Current Issues
My mail client currently requires GPG access to sync emails, which doesn't properly work. Using the mail client requires running mbsync -a externally instead.
Org Mode
A lot of my current Org mode configuration consists of relics of previous organizational systems, including the TODO states and capture templates. I don't currently use these, as most of my Org mode use has shifted towards Org-roam, so it might be a good idea to replace these with something more useful.
Doom Modules
One of Doom Emacs's most useful features is its modular configuration system, allowing configuration code to be sectioned into modules that can be enabled or customized individually. Doom provides a full suite of prewritten modules to enable.
;;; init.el -*- lexical-binding: t; -*-
;; This file controls what Doom modules are enabled and what order they load in.

)Config Modules
Considering this is a literate config, the corresponding :config literate module is necessary. We'll also turn on some of the default config options too.
:config

I'm a big fan of the Vertico ecosystem, as it's lightweight and easy to use. Let's turn on that module, along with the icons flag because why not.
:completion
(vertico +icons)
(company +childframe)Checkers
The two most common syntax checking engines seem to be flymake and flycheck. flymake is built in to Emacs, is generally faster and currently has better support in the ecosystem, so let's use that one.
We'll also enable a dedicated spell checking module using aspell, as that seems to be the recommended option.
:checkers
(syntax +flymake +childframe)
(spell +aspell)
;;grammarUI
Most of these are either defaults that come with Doom Emacs or just recommended, but here are the highlights:

;;zigBasic Configuration
This is mostly config settings that don't belong to any particular package and aren't important enough to get their own major section.
Sensible Settings
It wouldn't be Emacs if there wasn't an endless list of config variables to change every aspect of its function!
(setq-default tab-width 2 ; 2 width tabs
delete-by-moving-to-trash t ; Delete files to trash
window-combination-resize t ; Resize windows more evenly
)
(setq compile-command "nix build"
truncate-string-ellipsis "…" ; Unicode!
shell-file-name (executable-find "bash") ; Use bash instead of fish for default shell
disabled-command-function nil ; Disabled commands are a stupid idea
password-cache-expiry nil ; Security? Never heard of it
scroll-margin 2 ; A few extra lines on each end of the window
)
(global-subword-mode 1)Thanks once again to Tecosaur for some of these settings.
Personal Information
Emacs uses this basic personal information for a few different things, mostly applications.
(setq user-full-name "Kiana Sheibani"
user-mail-address "kiana.a.sheibani@gmail.com")Authentication
I don't want my cache files to get deleted whenever I mess up my Doom install, so let's move them to somewhere more safe.
(require 'auth-source-pass)
(setq auth-sources '(password-store "~/.authinfo.gpg")
auth-source-cache-expiry nil)Aesthetics
My favorite color theme has always been Tokyo Night. I use it literally everywhere I can, and Doom Emacs is no exception.
(setq doom-theme 'doom-tokyo-night)As for font choice, Victor Mono is my preferred coding font. I also use Source Sans Pro as my sans-serif font, though that is more out of obligation than actually liking how it looks.
(setq doom-font (font-spec :family "VictorMono" :size 13)
doom-variable-pitch-font (font-spec :family "Source Sans Pro" :size 16))I'm a very big fan of how italics look in this font, so let's make more things italicized! While we're here, we'll also set doom's modified buffer font to be red instead of yellow (I like how it looks better).
(custom-set-faces!
'(font-lock-comment-face :slant italic)
'(font-lock-variable-name-face :slant italic)
'(doom-modeline-buffer-modified :weight bold :inherit (doom-modeline error)))Some other small aesthetic changes:
(setq nerd-icons-scale-factor 1.1 ; Make icons slightly larger
doom-modeline-height 24 ; Make Doom's modeline taller
display-line-numbers-type t) ; Line numbers (absolute)Bindings
Windows & Workspaces
I like using window numbers to navigate between splitscreen windows, but having to type SPC w <#> every time is annoying. Let's shorten that key sequence by 67%, and also throw in a convenient binding for switching to treemacs.
(map! :leader
;; Bind "SPC 0" to treemacs
;; Map window bindings to "SPC 1" through "SPC 9"
"w 0" #'treemacs-select-window
:desc "Select project tree window" "0" #'treemacs-select-window
:desc "Select window 1" "1" #'winum-select-window-1
:desc "Select window 2" "2" #'winum-select-window-2
:desc "Select window 3" "3" #'winum-select-window-3
:desc "Select window 4" "4" #'winum-select-window-4
:desc "Select window 5" "5" #'winum-select-window-5
:desc "Select window 6" "6" #'winum-select-window-6
:desc "Select window 7" "7" #'winum-select-window-7
:desc "Select window 8" "8" #'winum-select-window-8
:desc "Select window 9" "9" #'winum-select-window-9)
Now SPC 1 will work equivalently to SPC w 1. Efficiency!
I like to reorganize my workspaces, so we can also add bindings to change the workspace order.
(map! :leader
:desc "Move workspace left"
"TAB h" #'+workspace/swap-left
:desc "Move workspace right"
"TAB l" #'+workspace/swap-right)Leader Key
It's sometimes useful to have a universal-argument binding that doesn't go through the leader key.
(map! :map global-map
"M-u" #'universal-argument)
It's also sometimes useful to have an evil-ex binding that does go through the leader key.
(map! :leader
"w :" nil
":" #'evil-ex)Evil Macros
Seeing as it's practically the Evil Emacs version of C-g, I often end up accidentally pressing q in a non-popup buffer, which starts recording a macro. That's very annoying, and I don't use macros enough to justify that annoyance.
(map! :map evil-normal-state-map
"q" nil
"C-q" #'evil-record-macro)Creating New Projects
Whenever I want to make a new project, having to create a new directory, initialize Git, and register it with Projectile is cumbersome. A new command to do all of those steps in one go sounds like a good idea.
(defun create-new-project (dir type &optional parents)
"Create a new directory DIR and add it to the list of known projects.
TYPE specifies the type of project to create. It can take the following values:
- `git', which creates a new Git repository.
- `projectile', which creates a .projectile file in the project root.
- A string, which is used as a filename to create in the project root.
- A function, which is called with no arguments inside the root of the project.
When called interactively, this defaults to `git' unless a prefix arg is given.
If PARENTS is non-nil, the parents of the specified directory will also be created."
(interactive (list (read-directory-name "Create new project: ")
(if current-prefix-arg
(intern (completing-read "Project type: "
'("git" "projectile") nil t))
'git) t))
(make-directory dir parents)
(let ((default-directory dir))
(pcase type
('git
(shell-command "git init"))
('projectile
(make-empty-file ".projectile"))
((pred stringp)
(make-empty-file type))
((pred functionp)
(funcall type))))
(projectile-add-known-project dir))
(map! :leader
:desc "Create new project"
"p n" #'create-new-project)Misc.
(map! :leader
:desc "Open URL"
"s u" #'goto-address-at-point)… This is Also Here
I'm not even going to bother explaining this one. Emacs is just janky sometimes lol
(defadvice! ~/projectile-find-file (invalidate-cache &optional ff-variant)
:override #'projectile--find-file
(projectile-maybe-invalidate-cache invalidate-cache)
(let* ((project-root (projectile-acquire-root))
(file (read-file-name "Find file: " project-root project-root
(confirm-nonexistent-file-or-buffer) nil
))
(ff (or ff-variant #'find-file)))
(when file
(funcall ff (expand-file-name file project-root))
(run-hooks 'projectile-find-file-hook))))Line Wrapping
I have rather specific tastes when it comes to line wrapping. I like soft line wrapping (visual-line-mode), but I want it to be as seamless as possible.
(setq +word-wrap-fill-style 'soft ; Soft line wrapping
evil-respect-visual-line-mode t ; Respect visual line mode
)
(setq-default fill-column 90) ; More space before wrap
For some reason, telling Evil to respect soft line wrapping doesn't change the behavior of j and k, so I'll do that myself.
(after! evil
(evil-define-motion evil-next-line (count)
"Move the cursor COUNT lines down."
:type line
(let ((line-move-visual evil-respect-visual-line-mode))
(evil-line-move (or count 1))))
(evil-define-motion evil-previous-line (count)
"Move the cursor COUNT lines up."
:type line
(let ((line-move-visual evil-respect-visual-line-mode))
(evil-line-move (- (or count 1))))))When a buffer has line numbers, they can interfere with the margins and make them smaller than they need to be.
(add-hook! display-line-numbers-mode
(setq-local visual-fill-column-extra-text-width '(0 . 6))
(visual-fill-column--adjust-window))Automated Nix Builds
Some packages in this config such as treemacs, org-roam, etc. require certain tools to be in the environment. On a Nix-based system, there are a few different ways to handle this:
- Put that tool in the actual environment, e.g. in a profile. This makes sense for simple things (
ripgrep,sqlite, etc) but for more opinionated things like an instance of Python it becomes less desirable. - Build the tool and put a symlink to the output somewhere, e.g. in the HOME directory. This avoids polluting the environment, but you still have to deal with an unwieldy symlink that breaks Emacs if you accidentally delete it. This was my approach before coming up with the third option:
- Build the tool and point Emacs directly to the store path. This is the simplest solution, but requires the most complex Emacs configuration.
This section is an implementation of that third solution.
We first need a function to build a flake reference:
(defun nix-build-out-path (out &optional impure)
"Build the given flake output OUT and return the output path. Return
nil if the build fails.
If IMPURE is t, then allow impure builds."
(message "Building \"%s\" ..." out)
(require 'nix) (require 's)
(let* ((args `("build" "--no-link" "--print-out-paths"
,@(if impure "--impure") ,out))
(buffer (generate-new-buffer " *nix-process*" t))
(status (apply #'call-process nix-executable nil
(list buffer nil) nil args)))
(prog1
(when (eql status 0)
(with-current-buffer buffer
(s-trim (buffer-string))))
(kill-buffer buffer))))This works well enough if we just want to build something, but there's a problem: we haven't indicated to Nix that we want this output to stick around, so it will be deleted the next time we garbage collect. To fix this, we can write a wrapper function that also makes the output path a garbage collection root.
(defun nix-build-out-path-gcroot (name out &optional impure)
"Build the given flake output OUT, register its output path as
a garbage collection root under NAME, and return the output path.
Return nil if the build fails.
The GC root is placed under \"/nix/var/nix/gcroots/emacs/NAME\". If
a call to this function reuses the same NAME argument, then the
symlink is overwritten.
If IMPURE is t, then allow impure builds."
(when-let* ((path (nix-build-out-path out impure))
(gcdir "/nix/var/nix/gcroots/emacs")
(sym (expand-file-name name gcdir)))
(unless (equal path (file-symlink-p sym))
(make-directory (concat "/sudo::" gcdir) t)
(make-symbolic-link path (concat "/sudo::" sym) t))
path))Packages
Now that we've enabled our preferred modules and done some basic configuration, we can install and configure our packages.
Our package! declarations go in packages.el, which must not be byte-compiled:
;; -*- no-byte-compile: t; -*-
Everything else goes in config.el, which is managed by confpkg as outlined earlier.
Company
TODO Optimization
Bindings
When Company is active, its keybindings overshadow the default ones, meaning keys like RET no longer work. To prevent this from happening, let's rebind company-complete-selection to TAB (less useful in the middle of typing), and only allow RET to be used if Company has been explicitly interacted with.
(after! company
(let ((item `(menu-item nil company-complete-selection
:filter ,(lambda (cmd)
(when (company-explicit-action-p)
cmd)))))
(map! :map company-active-map
"RET" item
"<return>" item
"TAB" #'company-complete-selection
"<tab>" #'company-complete-selection
"S-TAB" #'company-complete-common)))Spell Correction
I've been having problems with company-ispell, mainly due to Ispell requiring a text-based dictionary (unlike Aspell, which uses a binary dictionary). So let's switch to company-spell:
(package! company-spell)(after! company-spell
(map! :map evil-insert-state-map
"C-x s" #'company-spell))
We should make sure that company-spell uses Ispell's personal dictionary too:
(after! (company-spell ispell)
(setq company-spell-args
(concat company-spell-args " -p " ispell-personal-dictionary)))Icons
The company-box front-end adds support for icons, but there aren't many providers for them, especially in text. We'll add two new icon providers:
~/company-box-icons--text, which directly targets the output ofcompany-spell~/company-box-icons--spell, which is a fallback for all text completions
;; Mark candidates from `company-spell' using a text property
(defadvice! ~/company-spell-text-property (words)
:filter-return #'company-spell-lookup-words
(dolist (word words)
(put-text-property 0 1 'spell-completion-item t word))
words)
(defun ~/company-box-icons--spell (candidate)
(when (get-text-property 0 'spell-completion-item candidate)
'Text))
(defun ~/company-box-icons--text (candidate)
(when (derived-mode-p 'text-mode) 'Text))
(after! company-box
(pushnew! company-box-icons-functions #'~/company-box-icons--text)
;; `~/company-box-icons--text' is a fallback, so it has to go at the end of
;; the list
(setq company-box-icons-functions
(append company-box-icons-functions '(~/company-box-icons--text))))Eldoc
We'll switch the default docstring handler to eldoc-documentation-compose, since that provides the most information and I don't mind the space it takes up.
(after! eldoc
(setq eldoc-documentation-strategy 'eldoc-documentation-compose))Embark
When I first learned about Embark and began to use it, I was a bit disappointed by its defaults, especially since Doom Emacs is normally great when it comes to ensuring good defaults. I eventually went ahead and looked through every aspect of Embark to see what needed to change.
Targets
Some of the targeting functions are a bit too general in what they accept. We'll adjust the expression and identifier targeters to only work in prog-mode and the "defun" targeter to only work in Emacs Lisp code.
(defun ~/embark-target-prog-mode (old-fn)
"Advise an embark target to only activate in `prog-mode'."
(when (derived-mode-p 'prog-mode) (funcall old-fn)))
(defun ~/embark-target-identifier (old-fn)
"Advise an embark target to only activate in `prog-mode' and not in `lsp-mode'."
(when (and (derived-mode-p 'prog-mode) (not (bound-and-true-p lsp-mode))) (funcall old-fn)))
(advice-add #'embark-target-expression-at-point :around #'~/embark-target-prog-mode)
(advice-add #'embark-target-identifier-at-point :around #'~/embark-target-identifier)
(after! embark
(embark-define-thingatpt-target defun emacs-lisp-mode))We'll also define a word targeter, since that case was previously handled by the identifier one.
(defun embark-target-word-at-point ()
"Target word at point."
(when (or (derived-mode-p 'text-mode 'help-mode 'Info-mode 'man-common)
(doom-point-in-comment-p))
(when-let ((bounds (bounds-of-thing-at-point 'word)))
(cons 'word (cons (buffer-substring (car bounds) (cdr bounds)) bounds)))))
(after! embark
(pushnew! embark-target-finders #'embark-target-word-at-point))LSP Integration
The provided action types related to programming only apply to Emacs Lisp code, so we'll add a new one that integrates with LSP.
(defun embark-target-lsp-symbol-at-point ()
"Target the LSP symbol at point."
(when (bound-and-true-p lsp-mode)
(require 'lsp-ui-doc)
;; Use hover request (meant for highlighting) to get the current symbol
(when-let ((bounds (lsp-ui-doc--extract-bounds
(lsp-request "textDocument/hover"
(lsp--text-document-position-params)))))
(cons 'lsp-symbol
(cons (buffer-substring (car bounds) (cdr bounds))
bounds)))))
(after! embark
(pushnew! embark-target-finders #'embark-target-lsp-symbol-at-point))Hooks
The hook embark--mark-target normally sets the mark to the end and puts the point at the beginning. This is the opposite of the usual order, so let's override it to flip the order.
(after! embark
(cl-defun embark--mark-target (&rest rest &key run bounds &allow-other-keys)
"Mark the target if its BOUNDS are known.
After marking the target, call RUN with the REST of its arguments."
(cond
((and bounds run)
(save-mark-and-excursion
(set-mark (car bounds))
(goto-char (cdr bounds))
(apply run :bounds bounds rest)))
(bounds ;; used as pre- or post-action hook
(set-mark (car bounds))
(goto-char (cdr bounds)))
(run (apply run rest)))))Actions
We'll be using a lot of new actions, so let's set their hooks.

Operation Hints
I like having hints that show how large the editing operation I just performed was, but the ophints module in Doom doesn't look very good to me (it gets rid of pulses and color), so I'll override it.

Snippets are an extremely versatile way of avoiding unnecessary typing, especially when writing code.
Tweaks
Allow nested snippets:
(after! yasnippet
(setq yas-triggers-in-field t))Editing Snippets
Snippets are edited by visiting their file in snippet-mode, which defines some useful keybindings for working with the snippet.
Trailing Newlines
If there are any trailing newlines in the snippet file, they will be inserted when the snippet is expanded. This may not always be desirable, so we should prevent Emacs from automatically inserting trailing newlines in these buffers.
(add-hook! snippet-mode
(setq-local require-final-newline nil))Testing
When editing a snippet, the binding C-c C-t can be used to test it in a fresh buffer. This is very useful, but with Evil it has the issue of leaving the editor in normal state, when snippets are designed to be expanded in insert state.
(defadvice! ~/yas-tryout-insert-mode (&rest _)
"Switch to Insert state when trying out a snippet."
:after #'yas-tryout-snippet
(evil-insert-state))Creating New Snippets
Doom's command to create a new snippet, +snippets/new, defines a template inside of itself purely for when creating a snippet through this command. This doesn't make much sense to me when file templates already exist as a standard system in Doom, so we'll override this function to use that.
(defadvice! ~/snippets-new (&optional all-modes)
"Use standard file template when creating a new snippet."
:override #'+snippets/new
(let* ((mode (+snippets--snippet-mode-name-completing-read all-modes))
(default-directory (+snippet--ensure-dir (expand-file-name mode +snippets-dir)))
(snippet-key (read-string "Enter a key for the snippet: "))
(snippet-file-name (expand-file-name snippet-key)))
(when (+snippets--use-snippet-file-name-p snippet-file-name)
(switch-to-buffer snippet-key)
(snippet-mode)
(erase-buffer)
(set-visited-file-name snippet-file-name)
(+file-templates--expand t))))
Since the snippet is expanded in an environment including the variable snippet-key, our template can use that to automatically fill in the key we specified.
Treemacs
Treemacs is a really useful package, but it also has a lot of defaults I don't like. Let's add a use-package! declaration to fix some of them:
(use-package! treemacs
:defer t
:init
; More accurate git status
(setq +treemacs-git-mode 'deferred
treemacs-python-executable
(if-let ((path (nix-build-out-path-gcroot
"treemacs-python" "nixpkgs#python3")))
(concat path "/bin/python")
(error "Building python for treemacs failed")))
:config
(setq ; Child-frame reading is broken (and sucks anyways)
treemacs-read-string-input 'from-minibuffer
; Make "SPC 0" work like other window select commands
treemacs-select-when-already-in-treemacs 'stay)
; Better font styling
(custom-set-faces!

'((treemacs-git-added-face
treemacs-git-modified-face

treemacs-git-conflict-face) :inherit treemacs-file-face)
; Better colors
`(treemacs-git-ignored-face
:foreground ,(doom-color 'base1) :slant italic :inherit treemacs-file-face)
`(treemacs-git-untracked-face
:foreground ,(doom-color 'base1) :inherit treemacs-file-face)
'(treemacs-async-loading-face

(treemacs-hide-gitignored-files-mode) ; Hide git-ignored files by default
(treemacs-fringe-indicator-mode -1) ; No fringe indicator
(treemacs-resize-icons 16) ; Make icons smaller
)Project Integration
I often accidentally open the project tree before I've even selected a project, which I don't want because it messes up treemacs-projectile. Let's fix that problem:
(defun ~/treemacs-restrict (&rest _)
(unless (doom-project-p)
(user-error "Must be in a project to open project tree")))
(advice-add #'treemacs-select-window :before #'~/treemacs-restrict)
(advice-add #'+treemacs/toggle :before #'~/treemacs-restrict)When I do have a project open, Treemacs is flexible and allows you to open directories other than that project. This would be great and convenient if it weren't for the fact that it doesn't do so very well, often opening the wrong directories entirely. This convenience function ensures that only the project directory is open.
(defun ~/treemacs-fix-project ()
"Modify the current `treemacs' workspace to only include the current project."
(interactive)
(require 'treemacs)
(let* ((name (concat "Perspective " (doom-project-name)))
(project (treemacs-project->create!
:name (doom-project-name)
:path (directory-file-name (doom-project-root))
:path-status 'local-readable :is-disabled? nil))
(workspace (treemacs-workspace->create!
:name name :projects (list project) :is-disabled? nil)))
;; Only rebuild workspace if it doesn't have the structure we expect
(unless (equal (treemacs-current-workspace) workspace)
(setq treemacs--workspaces
(append (remove-if (lambda (w)
(string= (treemacs-workspace->name w) name)
treemacs--workspaces)
(list workspace))))
(treemacs-do-switch-workspace workspace)
(treemacs--invalidate-buffer-project-cache)
(treemacs--rerender-after-workspace-change))))VTerm
Set vterm to use fish as its shell:
(after! vterm
(setq-default vterm-shell (executable-find "fish")))Applications
Calculator
Emacs Calc is the best calculator I've ever used, and given the fact that it's an RPN calculator, that's saying something.
Leader Key Bindings
Typing C-x * every time I want to use Calc (very often) is annoying.
(map! :leader
:prefix ("#" . "calc")

"r" #'calc-embedded-update-formula

"`" #'calc-embedded-edit))
For the grab-region command, I think it makes sense to have it check whether your selection is a rectangle (C-v):
(defun ~/calc-grab-region (top bot &optional arg)
"Perform either `calc-grab-region' or `calc-grab-rectangle' depending on
what type of visual state is currently active."
(interactive "r\nP")
(if (eq (evil-visual-type) 'block)
(calc-grab-rectangle top bot arg)
(calc-grab-region top bot arg)))Evil Bindings
I want to have vim keybindings in Calc, so let's enable the evil-collection module for it. I haven't found a better way to do this than to edit the relevant variable in init.el:
;; Enable evil-collection-calc
(setq +evil-collection-disabled-list
'(anaconda-mode
buff-menu
comint
company
custom
eldoc
elisp-mode
ert
free-keys
helm
help
indent
image
kotlin-mode
outline
replace
shortdoc
simple
slime
lispy))
Let's also rebind some keys. Preserving evil's [ and ] bindings doesn't make sense to me, and C-r makes more sense as a redo binding than D D.
(defadvice! ~/evil-collection-calc-bindings ()
:after #'evil-collection-calc-setup
(map! :map calc-mode-map
:n "C-r" #'calc-redo
:n "[" #'calc-begin-vector
:n "]" #'calc-end-vector))Appearance
Calc doesn't use faces to show selections by default, which I think is rather strange.
(after! calc
(setq calc-highlight-selections-with-faces t
calc-show-selections nil)
(custom-set-faces!
`(calc-selected-face :weight extra-bold :foreground ,(doom-color 'highlight))

Emacs Everywhere is a great idea. Unfortunately, the default package on MELPA uses X-based window commands, while I use Hyprland, which is Wayland-based. To fix this issue, we need to override some of the package's variables and functions.

)
;; Move to right side

I love org-mode. In fact, I love it so much that I'm willing to give it its own top-level section in this config! Its power and flexibility are unmatched by any other productivity/organization tool I've ever used. Much like Emacs itself, all alternatives simply vanish.
Unfortunately, with that power comes a lot of configuration work up-front. It was completely worth it for me when I made it out the other end, but that doesn't mean everyone would have the time or patience to make it work.

Convenience
There are a few useful functions Doom doesn't bind by default, so let's add them for convenience.
(map! :after org
:map org-mode-map
:localleader
"N" #'org-num-mode
"C" #'org-columns
"p" #'org-priority ; Remove extraneous commands
"c D" #'org-clock-display
"m b f" #'org-table-eval-formula
"m b F" #'org-table-edit-formulas
;; Map babel commands into localleader
:desc "babel"
"v" (lookup-key org-mode-map (kbd "C-c C-v")))YASnippet
By default, snippet expansion doesn't work in Org mode; when TAB is pressed to move to the next placeholder, headline visibility cycling is triggered instead. This is because in org-mode-map TAB is unconditionally bound to org-cycle, and for some reason this has a higher precedence than YAS's keymaps.
While this is a complex problem, the solution is actually rather simple: just remove the org-mode-map binding. The org-cycle command will still be triggered on TAB when in normal mode, as it is bound in evil-org-mode-map, but when in insert mode (as one generally is during snippet expansion) the binding will fall through both maps and be handled by YASnippet.
(map! :after org
:map org-mode-map
"TAB" nil
"<tab>" nil)
This also means we don't need org-cycle to emulate indentation, which is nice.
Appearance
When marking text for *emphasis*, Org mode normally only allows emphasized sections to span 2 lines. This strikes me as needlessly limited, so let's bump up that number to 20 lines.
(after! org
(setf (nth 4 org-emphasis-regexp-components) 20))Project Links
It's sometimes nice to be able to click a link in an Org file that takes me to one of my projects.
(defun org-projectile-follow (path _)
"Open a projectile link to PATH."
(projectile-switch-project-by-name path))
(defun org-projectile-completion (&optional arg)
(let ((project (completing-read "Project: " projectile-known-projects nil 'confirm)))
(concat "projectile:" project)))
(after! org
(org-link-set-parameters "projectile"
:follow #'org-projectile-follow
:complete #'org-projectile-completion))Enhancements
Export Directory
Org mode by default exports to the same directory the org-mode file is in. This is inconvenient for me, as I use a lot of subdirectories. To fix this, we can advise the function org-export-output-file-name.
(defvar org-export-dir (expand-file-name "export/" org-directory)
"The directory to export Org mode files to.
If nil, then `default-directory' for the org buffer is used.")
(defadvice! ~/modify-org-export-dir (orig-fn extension &optional subtreep pub-dir)
:around #'org-export-output-file-name
(unless pub-dir
(setq pub-dir org-export-dir))
(unless (file-directory-p pub-dir)
(make-directory pub-dir t))
(funcall orig-fn extension subtreep pub-dir))Todo Date Overriding
My attention span being what it is, I often forget to update TODO entries in my Org files until long after the task has been completed. I rely heavily on tracking TODOs through timestamps, so it would be nice to have a command to override the date. To do this, we can create a new variable org-todo-time that will specify the time to update TODOs with.
(defvar org-todo-time nil
"The time to use when updating TODO entries.
If nil, then use the current time.")
(defadvice! ~/org-override-time (old-fn)
"Use `org-todo-time' as the current time if it is specified."
:around #'org-current-effective-time
(or org-todo-time (funcall old-fn)))
We can then define and bind alternate versions of org-todo and org-agenda-todo that allow us to pick the time to set.
(defmacro ~/org-wrap-todo (fn)
"Wrap a command to set `org-todo-time'."
(let ((new-fn (intern (format "%s-date" fn))))
`(defun ,new-fn (&optional arg)
,(format "Call `%s', but allow the user to pick a time first." fn)
(interactive "P")
(let ((org-todo-time (org-read-date t t)))
(,fn arg)))))

(map! :mode evil-org-agenda-mode

:m "T" #'org-agenda-todo-date)Tags
Org mode offers a useful tag hierarchy system, configured via org-tag-alist. We'll be using org-tag-persistent-alist instead so that our tag hierarchy can't be overwritten.
(defvar classes-mwf '()
"Classes that belong under the :MWF: tag.")
(defvar classes-tr '()
"Classes that belong under the :TR: tag.")
(defvar classes-online '()
"Classes that belong under the :Online: tag.")

When I started out using Org mode, I just used vanilla Org files to manage my notes. This worked, but as my notes grew more and more I've begun to increasingly rely on Org-roam to more systematically manage my organization.
Concept
Org-roam is inspired by Roam Research, and like that tool it is based on the Zettelkasten (slip-box) note-taking method. In the Zettelkasten method, notes and concepts are separated into small chunks (called "nodes" in Org-roam terminology). These notes can live freely in any file on your system, and are linked to each other through ID links, leading to a freer note system that isn't tied to any particular organizational structure or hierarchy.
Task Management
In my use of Org-roam for task management, I divide nodes into a few different categories:
- Areas, which represent continual areas of your life to organize and plan;
- Goals, short- or long-term, things that can be completed;
- Tasks, which are one-time and contribute to goals or areas.
Areas are stored as subnodes of the Areas file node, and likewise for goals. They also have the :area: and :goal: tags respectively. A task is a node that is a TODO entry that links to an area or a goal. We can thus check for if a node is a task by checking if the node links to a :area: or :goal: tagged node.
(defun ~/org-roam-get-linked-nodes (node tag)
"Return the nodes that NODE links to that are tagged with TAG."
(let* ((response (org-roam-db-query [:select :distinct [dest]
:from links
:where (= source $s1)
:and (= type "id")
:group :by dest]
(org-roam-node-id node)))

(--keep (let ((node (org-roam-node-from-id it)))
(when (-contains? (org-roam-node-tags node) tag)

The unlinked references section is turned off by default for performance reasons, but I've never had any serious issues with it. Let's turn that on, and also make sure backlinks are unique.

Creating new nodes should be quick and easy, so we should stick to one template to avoid the hassle of choosing.
(defun org-roam-node-file-maybe (node &optional dir)
"Get file name from NODE, or return a default filename in directory DIR."
(unless dir (setq dir org-roam-directory))

The Org agenda is a very nice feature, but by default it doesn't really provide enough customization to fit my needs. I like to have nice categories to make parsing my todos easier, so we'll use org-super-agenda:

The org-agenda dispatcher is occasionally useful, but most of the time when I want to open my agenda, it's to see my "preferred" view.

Org mode has a very robust system for specifying citations, one which is taken advantage of by the package citar.

Despite Emacs being my editor of choice for programming, I don't actually have a lot of configuration for programming languages. I suppose that this is because language packages tend to not need much configuration, as the bounds of what a language mode needs to do are typically defined by the language itself.
