My doom emacs configuration
* Basic Doom stuff
The provided default ~config.el~
#+begin_src emacs-lisp
;;; $DOOMDIR/config.el -*- lexical-binding: t; -*-
;; Place your private configuration here! Remember, you do not need to run 'doom
;; sync' after modifying this file!
;; Some functionality uses this to identify you, e.g. GPG configuration, email
;; clients, file templates and snippets. It is optional.
(setq user-full-name "Nathan McCarty"
user-mail-address "nathan@mccarty.io")
;; Doom exposes five (optional) variables for controlling fonts in Doom:
;;
;; - `doom-font' -- the primary font to use
;; - `doom-variable-pitch-font' -- a non-monospace font (where applicable)
;; - `doom-big-font' -- used for `doom-big-font-mode'; use this for
;; presentations or streaming.
;; - `doom-unicode-font' -- for unicode glyphs
;; - `doom-serif-font' -- for the `fixed-pitch-serif' face
;;
;; See 'C-h v doom-font' for documentation and more examples of what they
;; accept. For example:
;;
(setq doom-font (font-spec :family "FiraCode Nerd Font" :size 11 :weight 'semi-light)
doom-variable-pitch-font (font-spec :family "Fira Sans" :size 15))
;;
;; If you or Emacs can't find your font, use 'M-x describe-font' to look them
;; up, `M-x eval-region' to execute elisp code, and 'M-x doom/reload-font' to
;; refresh your font settings. If Emacs still can't find your font, it likely
;; wasn't installed correctly. Font issues are rarely Doom issues!
;; There are two ways to load a theme. Both assume the theme is installed and
;; available. You can either set `doom-theme' or manually load a theme with the
;; `load-theme' function. This is the default:
;; (setq doom-theme 'doom-solarized-dark)
(use-package! solarized-theme
:demand t
:config
(setq solarized-distinct-fringe-background t
solarized-distinct-doc-face t
solarized-scale-markdown-headlines t
solarized-scale-org-headlines t)
(load-theme 'solarized-selenized-dark t))
;; This determines the style of line numbers in effect. If set to `nil', line
;; numbers are disabled. For relative line numbers, set this to `relative'.
(setq display-line-numbers-type t)
;; If you use `org' and don't want your org files in the default location below,
;; change `org-directory'. It must be set before org loads!
(setq org-directory "~/Org/")
;; Whenever you reconfigure a package, make sure to wrap your config in an
;; `after!' block, otherwise Doom's defaults may override your settings. E.g.
;;
;; (after! PACKAGE
;; (setq x y))
;;
;; The exceptions to this rule:
;;
;; - Setting file/directory variables (like `org-directory')
;; - Setting variables which explicitly tell you to set them before their
;; package is loaded (see 'C-h v VARIABLE' to look up their documentation).
;; - Setting doom variables (which start with 'doom-' or '+').
;;
;; Here are some additional functions/macros that will help you configure Doom.
;;
;; - `load!' for loading external *.el files relative to this one
;; - `use-package!' for configuring packages
;; - `after!' for running code after a package has loaded
;; - `add-load-path!' for adding directories to the `load-path', relative to
;; this file. Emacs searches the `load-path' when you load packages with
;; `require' or `use-package'.
;; - `map!' for binding new keys
;;
;; To get information about any of these functions/macros, move the cursor over
;; the highlighted symbol at press 'K' (non-evil users must press 'C-c c k').
;; This will open documentation for it, including demos of how they are used.
;; Alternatively, use `C-h o' to look up a symbol (functions, variables, faces,
;; etc).
;;
;; You can also try 'gd' (or 'C-c c d') to jump to their definition and see how
;; they are implemented.

* Appearance and UI
** Centaur tabs
#+begin_src emacs-lisp
(after! centaur-tabs
(setq centaur-tabs-set-icons t
centaur-tabs-set-bar 'underflow
centaur-tabs-style "alternate")
(centaur-tabs-headline-match)
(centaur-tabs-group-by-projectile-project))
#+end_src
** Mixed Pitch Mode
Use mixed pitch mode in prose writing modes, to make the writing experience a bit more pleasant.
This tweak applies to:
- ~org-mode~
- ~markdown-mode~
#+begin_src emacs-lisp
(use-package! mixed-pitch
:hook
(org-mode . mixed-pitch-mode)
(markdown-mode . mixed-pitch-mode)
:config
(setq mixed-pitch-set-height t))
#+end_src
Setting ~mixed-pitch-set-height~ is required to get ~mixed-pitch-mode~ to render fonts with the correct size in doom emacs, apparently.
* Basic Editing
** Navigation
*** Avy
More modern ace-jump-mode
Set up our key bindings
#+begin_src emacs-lisp
(after! avy
(define-key!
"C-:" 'avy-goto-char
"C-'" 'avy-goto-char-2
"M-g f" 'avy-goto-line
"M-g w" 'avy-goto-word-1
"M-g e" 'avy-goto-word-0)
(cheatsheet-add-group 'Avy
'(:key "C-:" :description "Goto Char")
'(:key "C-'" :description "Goto Char (2)")
'(:key "M-g f" :description "Goto line")
'(:key "M-g w" :description "Goto word")
'(:key "M-g e" :description "Goto word (0)")))
#+end_src
*** Swiper
Better isearch
Override old isearch
#+begin_src emacs-lisp
(after! swiper
(define-key! "C-s" 'swiper))
#+end_src
** Crux
Smarter replacements for emacs built ins, with the following in use:
- ~crux-smart-kill-line~ - Smart ~C-k~ replacement
- ~crux-top-join-line~ - ~C-c ^~ Join two lines
#+begin_src emacs-lisp
(use-package! crux
:bind (("C-k" . crux-smart-kill-line)
("C-c ^" . crux-top-join-line)))
#+end_src
** string-inflection
Automatically cycle case of names
#+begin_src emacs-lisp
(global-unset-key (kbd "C-q"))
(use-package! string-inflection
:bind (("C-q" . string-inflection-all-cycle)))
(cheatsheet-add-group 'string-inflection
'(:key "C-q" :description "Rotate case"))
#+end_src
** Smart Hungry Delete
Gobble up whitespace in a smarter way
#+begin_src emacs-lisp
(use-package! smart-hungry-delete
:bind (("M-<backspace>" . smart-hungry-delete-backward-char)))
#+end_src
** Search
*** Deadgrep
Ripgrep, but from within emacs
#+begin_src emacs-lisp
(use-package! deadgrep
:bind ("C-c s r" . deadgrep))
#+end_src
* Org Mode
Improvements to the best mode in emacs
Setup some basic cosmetic improvements
- Disable showing of emphasis markers
- Show entities as utf-8 ~test~
#+begin_src emacs-lisp
(setq org-hide-emphasis-markers t
org-pretty-entities t)
#+end_src
Setup font lock for normal (non-heading) list items, to make things a bit more pleasnt to look at
#+begin_src emacs-lisp
(font-lock-add-keywords 'org-mode
'(("^ *\\([-]\\) "
0 (prog1 () (compose-region (match-beginning 1) (match-end 1) "")))
("^ *\\([+]\\) "
0 (prog1 () (compose-region (match-beginning 1) (match-end 1) "")))))
#+end_src
** org-roam
A second brain in emacs
Here we:
- Set the roam directory to be a sub-directory of the org directory, which I have in syncthing
- Use a more informative display template, as we use ivy
- Turn on db autosync
- Setup dalies to add the time of the capture to the note
#+begin_src emacs-lisp
(use-package! org-roam
:custom
(org-roam-directory (concat org-directory "Roam/"))
(org-roam-complete-everywhere t)
:bind (("C-c r l" . org-roam-buffer-toggle)
("C-c r f" . org-roam-node-find)
("C-c r g" . org-roam-graph)
("C-c r i" . org-roam-node-insert)
("C-c r c" . org-roam-capture)
("C-c r T" . org-roam-dailies-capture-today)
("C-c r t" . org-roam-dailies-goto-today)
:map org-mode-map
("C-M-i" . completion-at-point))
:config
(setq org-roam-node-display-template (concat "${title:*} " (propertize "${tags:10}" 'face 'org-tag)))
(org-roam-db-autosync-mode)
(setq org-roam-dailies-capture-templates
'(("d" "default" entry "* %<%I:%M %p>: %?"
:if-new (file+head "%<%Y-%m-%d>.org" "#+title: %<%Y-%m-%d>\n")))))
#+end_src
* General Modes
** Magit
Further configuration for magit
*** magit-todos
Count the number of todos in the project in the ~magit-status~ buffer
#+begin_src emacs-lisp
(use-package! magit-todos
:hook (magit-mode . magit-todos-mode))
#+end_src
*** magit-delta
Use delta for git diff display
#+begin_src emacs-lisp
(use-package! magit-delta
:hook (magit-mode . magit-delta-mode))
#+end_src
*** magit-wip-mode
Stash autosaves inside of git
#+begin_src emacs-lisp
(magit-wip-mode)
#+end_src
** System integration
Various tools for interacting with the system from within emacs
*** Terminal
Doom already provides pretty nice vterm support, but lets take us a step further, using ~multi-vterm~ to provide ergonomic support for multiple terminals.
Vterm really doesn't like being installed through emacs on nix, so proper support for it in my setup requires installing it through nix like so:
#+begin_src nix :tangle no
let emacsPackage = (emacsPackagesFor emacs).emacsWithPackages (epgks: with epkgs; [
vterm
]);
in
{
environment.systemPackages = [
emacsPackage
];
}
#+end_src
**** [[https://github.com/suonlight/multi-vterm][multi-vterm]]
Add ergonomic support for multiple vterm terminals
#+begin_src emacs-lisp
(use-package! multi-vterm
:bind (("C-c o M" . multi-vterm)
("C-c o m" . multi-vterm-project)))
#+end_src
* Programming
** General Editing
*** Sepraedit
Edit indirect for comments
Set the default mode to github flavored markdown, turn on smart use of fill column, and bind to the normal edit-indirect keybinding.
#+begin_src emacs-lisp
(use-package! separedit
:bind
(:map prog-mode-map
("C-c '" . separedit))
:config
(setq separedit-default-mode 'gfm-mode
separedit-continue-fill-column t))
#+end_src
** LSP Mode
Custom configuration for lsp-mode
*** LSP UI
Turn on the UI features we want
**** Sideline
Show as much as possible in the sideline
#+begin_src emacs-lisp
(after! lsp-ui
(setq lsp-ui-sideline-show-diagnostics t
lsp-ui-sideline-show-hover t
lsp-ui-sideline-show-code-actions t))
#+end_src
**** Peeking
Turn on peeking, and show us the directory as well
#+begin_src emacs-lisp
(after! lsp-ui
(setq lsp-ui-peek-enable t
lsp-ui-peek-show-directory t))
#+end_src
**** Documentation
Show the documentation in a popup frame in the top right corner
#+begin_src emacs-lisp
(after! lsp-ui
(setq lsp-ui-doc-enable t
lsp-ui-doc-position 'top
lsp-ui-doc-show-with-cursor t))
#+end_src
** Rust
Configuration specific for rust
*** LSP Tweaks
Most of these are defaults, but I like having them explicit for my sanity
#+begin_src emacs-lisp
(after! lsp-mode
(setq lsp-auto-configure t
lsp-lens-enable t
lsp-rust-analyzer-cargo-watch-command "clippy"
lsp-rust-analyzer-cargo-watch-args ["--all-features"]
lsp-rust-analyzer-experimental-proc-attr-macros t
lsp-rust-analyzer-proc-macro-enable t
lsp-rust-analyzer-use-rustc-wrapper-for-build-scripts t
lsp-rust-analyzer-import-enforce-granularity t))
#+end_src
* Composition
Modes for handling plain text and prose
** Markdown
Everybody's favorite markup format
*** Markdown mode
Make the following configuration tweaks to result in a better markdown experience:
- Use a variable pitch font (this is prose after all)
- Turn on header scaling
- Default to gfm mode for readmes
- Turn on auto-fill mode
- Hide mark up
- Fontify code blocks with the language's native mode
The goal here is to create a more pretty and fluid composition environment for prose, closer to what you would get in a word processor, but without the horrors of wysiwyg.
#+begin_src emacs-lisp
(use-package! markdown-mode
:mode ("README\\.md" . gfm-mode)
:hook (markdown-mode . variable-pitch-mode)
(markdown-mode . auto-fill-mode)
:config
(setq markdown-header-scaling t
markdown-hide-markup t
markdown-fontify-code-blocks-natively t))
#+end_src
*** Grip mode
Provide a live, rendered preview when editing markdown readmes using [[https://github.com/joeyespo/grip][grip]].
#+begin_src emacs-lisp
(use-package! grip-mode
:bind (:map markdown-mode-command-map
("g" . grip-mode)))
#+end_src
* Applications
Emacs is good for more than just editing text
** RSS
Use ~elfeed~ for RSS. Doom provides most of the configuration, but we'll make a few minor tweaks:
- Automatically update the feed when opening elfeed
- Set default filter to only show unread posts
- Put the elfeed directory in the org dir (I have it in syncthing)
- Create a global keybinding for elfeed (~C-x w~)
#+begin_src emacs-lisp
(use-package! elfeed
:hook (elfeed-search-mode . elfeed-update)
:bind ("C-x w" . elfeed)
:config
(setq elfeed-search-filter "@2-weeks-ago +unread"
elfeed-db-directory (concat org-directory "elfeed/db/")
elfeed-enclosure-default-dir (concat org-directory "elfeed/enclosures/"))
(make-directory elfeed-db-directory t))
#+end_src
