* About This Configuration
Originally, nicknamed "Engineered Emacs," this configuration was my attempt to compete with Doom, Prelude, and Spacemacs, providing a simple yet effective setup for typical languages found in embedded engineering and data science. However, like all others, I eventually realized I want to use Emacs for more, and I can't call it a proper distribution or beginners' configuration if I include everything I want.

Therefore, I decided the best course of action was to just make it my own configuration, included with my dotfiles, and include all that I need to work efficiently instead of worrying about everyone else.

* Early Init
This is tangled to `~/.emacs.d/early-init.el` and is run, as the name
implies, earlier than the rest.

#+BEGIN_SRC emacs-lisp :tangle ~/.emacs.d/early-init.el
  ;;; early-init.el -*- lexical-binding: t; -*-
  ;; Do not edit this file! Generated by Emacs.org in .files

  ;; Got to disable package.el, we're using straight.el!

  (setq package-enable-at-startup nil)

  ;; Again, /inspired/ from Doom, ensure Engineered is running in this directory.
  (setq user-emacs-directory (expand-file-name "~/.local/emacs/")
        url-history-file (expand-file-name "url/history" user-emacs-directory))
#+END_SRC

* Startup
** Performance, Security, Tidying
Once again remnants of the framework. This was my "foundation" or "core" file,
and I pulled out the parts I thought were best and still needed.

  ;;; Security

  (setq locale-coding-system 'utf-8)
#+END_SRC

** Package Management
For my configuration, I decided to use straight.el instead of package.el. I've
heard much good about straight, so time to put that to the test.

#+BEGIN_SRC emacs-lisp
  ;; MELPA!
  (require 'package)
  (add-to-list 'package-archives '("melpa" . "https://melpa.org/packages/") t)
  (add-to-list 'package-archives '("org" . "https://orgmode.org/elpa/") t)
  (add-to-list 'package-archives '("gnu" . "https://elpa.gnu.org/packages/") t)
  (package-initialize)

  (setq load-prefer-newer t)

  (defvar bootstrap-version)
  (defvar native-comp-deferred-compilation-deny-list ())
  (let ((bootstrap-file
         (expand-file-name "straight/repos/straight.el/bootstrap.el" user-emacs-directory))
        (bootstrap-version 5))

        (goto-char (point-max))
        (eval-print-last-sexp)))
    (load bootstrap-file nil 'nomessage))
  (straight-use-package 'use-package)
  (setq straight-use-package-by-default t)
#+END_SRC

** Better Defaults and UI
Inspired from a multitude of different configs, this removes the Emacs menu bar
and other bits of the UI, and includes some limits I consider useful.

Add my name and email address as default

#+BEGIN_SRC emacs-lisp
(setq user-full-name "Daniil Rose"
      user-mail-address "daniil.rose@member.fsf.org")
#+END_SRC

Hide annoying minor modes that will always be on anyway.

#+BEGIN_SRC emacs-lisp
  (use-package diminish)
#+END_SRC

Let's get rid of the ugly UI elements that take up screen space.

#+BEGIN_SRC emacs-lisp
  (scroll-bar-mode -1)
  (tool-bar-mode   -1)
  (tooltip-mode    -1)
  (menu-bar-mode   -1)
#+END_SRC

When working with long lines, this should help with loading times and
lag.

#+BEGIN_SRC emacs-lisp
  (use-package so-long
    :config
    (global-so-long-mode 1))
#+END_SRC

When on macOS, make some tweaks to better the experience.

#+BEGIN_SRC emacs-lisp
(when IS-MAC
  ;; Switch keys around, since it's easier to hit Command
  (setq mac-option-key-is-meta nil
        mac-command-key-is-meta t
        mac-command-modifier 'meta
        mac-option-modifier 'super)

  ;; Use spotlight as search
  (setq locate-command "mdfind")

  ;; Curse Lion and its sudden but inevitable fullscreen mode!
  ;; NOTE Meaningless to railwaycat's emacs-mac build
  (setq ns-use-native-fullscreen nil)

  ;; Visit files opened outside of Emacs in existing frame, not a new one
  (setq ns-pop-up-frames nil)

  ;; sane trackpad/mouse scroll settings
  (setq mac-redisplay-dont-reset-vscroll t
        mac-mouse-wheel-smooth-scroll nil)

  ;; Sets `ns-transparent-titlebar' and `ns-appearance' frame parameters so window
  ;; borders will match the enabled theme.
  (and (or (daemonp)
           (display-graphic-p))
       (require 'ns-auto-titlebar nil t)
       (ns-auto-titlebar-mode +1))

  ;; Integrate with Keychain
  (add-to-list 'auth-sources 'macos-keychain-internet)
  (add-to-list 'auth-sources 'macos-keychain-generic)

  ;; Delete files to trash
  (use-package osx-trash
    :init
    (setq delete-by-moving-to-trash t)
    (and IS-MAC
         (not (fboundp 'system-move-file-to-trash))
         (defalias #'system-move-file-to-trash #'osx-trash-move-file-to-trash))))
#+END_SRC

Add programs to path on macOS.

#+BEGIN_SRC emacs-lisp
  (when IS-MAC
    (use-package exec-path-from-shell
      :init
      (exec-path-from-shell-initialize)))
#+END_SRC

Highlight selected regions ala Vim.

#+BEGIN_SRC emacs-lisp
(use-package volatile-highlights
  :hook (after-init . volatile-highlights-mode))
#+END_SRC

The most common protocol I use TRAMP for is ssh, so might as well make
that default. Also allow me to reopen a file as root automatically.

#+BEGIN_SRC emacs-lisp
  (setq tramp-default-method "ssh")

  (use-package auto-sudoedit
    :diminish auto-sudoedit-mode
    :config
    (auto-sudoedit-mode 1))
#+END_SRC

Another supposed performance boost, I do not need VC checking every
time I open a file, and I usually use Magit anyway.

#+BEGIN_SRC emacs-lisp
  (remove-hook 'find-file-hooks 'vc-find-file-hook)
  (setq vc-follow-symlinks t)
#+END_SRC

I prefer to have a little message in scratch and keep it in fundamental mode.

#+BEGIN_SRC emacs-lisp
  (setq initial-scratch-message "Welcome to Engineered Emacs!")
  (setq initial-major-mode 'fundamental-mode)
#+END_SRC

I absolutely hate the bell, please shut up.

#+BEGIN_SRC emacs-lisp
  (setq ring-bell-function 'ignore)
#+END_SRC

Tabs are for monsters, this is not up for debate.

#+BEGIN_SRC emacs-lisp
  (setq-default indent-tabs-mode nil)
  (setq-default tab-width 2)
#+END_SRC

Some other nice changes: files to trash, stretch cursor on glyph, and
undo limit increase.

#+BEGIN_SRC emacs-lisp
  (setq-default
   window-combination-resize t
   delete-by-moving-to-trash t
   x-stretch-cursor t)

  (setq undo-limit 80000000
        auto-save-default nil
        truncate-string-ellipsis "…"
        scroll-margin 20)
#+END_SRC

Iterating through CamelCase words is quite nice, especially in JVM
langs.

#+BEGIN_SRC emacs-lisp
  (with-eval-after-load 'subword
    (diminish 'subword-mode))
  (global-subword-mode 1)
#+END_SRC

Allow me to pop multiple times when jumping back to a mark.

#+BEGIN_SRC emacs-lisp
  (setq set-mark-command-repeat-pop t)
#+END_SRC

Always update files on change globally.

#+BEGIN_SRC emacs-lisp
  (setq global-auto-revert-non-file-buffers t)
  (global-auto-revert-mode 1)
#+END_SRC

I don't really need line numbers.

#+BEGIN_SRC emacs-lisp
(line-number-mode nil)
#+END_SRC

Update that load path.

#+BEGIN_SRC emacs-lisp
(add-to-list 'load-path "~/.emacs.d/lisp/")
#+END_SRC

Scroll one line at a time with the keyboard.

#+BEGIN_SRC emacs-lisp
(setq scroll-step 1)
#+END_SRC

I don't feel like writing the whole word!

#+BEGIN_SRC emacs-lisp
(defalias 'yes-or-no-p 'y-or-n-p)
#+END_SRC

Helps clean up some more.

#+BEGIN_SRC emacs-lisp
(setq backup-directory-alist '(("." . "~/.emacs.d/backup"))
      backup-by-copying t    ; Don't delink hardlinks
      version-control t      ; Use version numbers on backups
      delete-old-versions t  ; Automatically delete excess backups
      kept-new-versions 20   ; how many of the newest versions to keep
      kept-old-versions 5)
#+END_SRC

Ew, trailing whitespace

#+BEGIN_SRC emacs-lisp
(add-hook 'before-save-hook 'delete-trailing-whitespace)
#+END_SRC

I love the Jetbrains Mono font, make sure you have it installed or change
this font name! And if we're talking about fonts, you gotta have
emojis.

Also, set the default Emacs window to the size I like on my MacBook.

#+BEGIN_SRC emacs-lisp
(add-to-list 'default-frame-alist '(font . "JetBrainsMono Nerd Font"))
(use-package emojify
  :hook (after-init . global-emojify-mode)
  :custom
  (emojify-set-emoji-style 'unicode)
  :commands emojify-mode)
#+END_SRC

Improve text scaling.

#+BEGIN_SRC emacs-lisp
(use-package default-text-scale
  :defer 1
  :config
  (default-text-scale-mode))
#+END_SRC

The normal auto-save mode annoys me, but I've found super-save to be
useful.

#+BEGIN_SRC emacs-lisp
(use-package super-save
  :defer 1
  :diminish super-save-mode
  :config
  (super-save-mode +1)
  (setq super-save-auto-save-when-idle t))
#+END_SRC

Buffer placement can be strange in default Emacs, so let's improve
that.

#+BEGIN_SRC emacs-lisp
(setq display-buffer-base-action
      '(display-buffer-reuse-mode-window
        display-buffer-reuse-window
        display-buffer-same-window))

;; If a popup does happen, don't resize windows to be equal-sized
(setq even-window-sizes nil)
#+END_SRC

Dired is my favourite file manager, but it can be improved even more
with various packages.

Icons in Dired! And previews!

#+BEGIN_SRC emacs-lisp
(use-package all-the-icons-dired)
(use-package peep-dired)

(add-hook 'dired-mode-hook 'all-the-icons-dired-mode)
#+END_SRC

Tree view is also quite nice to have.

#+BEGIN_SRC emacs-lisp
(use-package dired-subtree
  :bind (:map dired-mode-map
              ("i" . dired-subtree-insert)
              (";" . dired-subtree-remove)))
#+END_SRC

Copy and paste files in Dired, making it feel even more like a GUI
file manager.

#+BEGIN_SRC emacs-lisp
(use-package dired-ranger
  :bind (:map dired-mode-map
              ("W" . dired-ranger-copy)
              ("X" . dired-ranger-move)
              ("Y" . dired-ranger-paste)))
#+END_SRC

Auto revert Dired as well, to ensure the latest information is
present.

#+BEGIN_SRC emacs-lisp
(add-hook 'dired-mode-hook 'auto-revert-mode)
#+END_SRC

With dired-open plugin, you can launch external programs for certain
extensions. For example, I set all .png files to open in 'sxiv' and
all .mp4 files to open in 'mpv'.

#+BEGIN_SRC emacs-lisp
(setq dired-open-extensions '(("gif" . "sxiv")
                              ("jpg" . "sxiv")
                              ("png" . "sxiv")
                              ("mkv" . "mpv")
                              ("mp4" . "mpv")))
#+END_SRC

** Evil (Sometimes)
Evil is the extensible vi layer for Emacs. When I'm in the mood for
(n)vi(m) keybindings, I use Evil, and this allows me to quickly switch
them on or off.

#+BEGIN_SRC emacs-lisp
(setq catster/use-evil nil)

(when catster/use-evil
   (require 'catsters-evil))
#+END_SRC

** Theme and Modeline
By default, Engineered Emacs uses ~smart-mode-line~, and Atom One Dark Pro
as the color theme. I think this strikes a good balance of usefulness and
readability.

#+BEGIN_SRC emacs-lisp
(use-package atom-one-dark-theme
  :config
  (load-theme 'atom-one-dark t))
(use-package all-the-icons)
#+END_SRC

I'm still not sold on the Doom modeline, but I'm willing to try it
again.

#+BEGIN_SRC emacs-lisp
(setq catster/use-doom-ml t)

(when catster/use-doom-ml
  (use-package doom-modeline
    :custom
    (doom-modeline-major-mode-icon t)
    (doom-modeline-minor-modes nil)
    :hook (after-init . doom-modeline-mode)))

(unless catster/use-doom-ml
  (use-package smart-mode-line-atom-one-dark-theme)
  (use-package smart-mode-line
    :after smart-mode-line-atom-one-dark-theme
    :init
    (setq sml/theme 'atom-one-dark)
    (setq sml/no-confirm-load-theme t)
    :config
    (sml/setup)))
#+END_SRC

Anzu shows you what result you are on out of n when searching, ala
Vim. Not the most useful since I use Consult and friends.

#+BEGIN_SRC emacs-lisp
(use-package anzu
  :init
  (global-anzu-mode))
#+END_SRC

** PGP
Let's handle encryption with Emacs as well.

#+BEGIN_SRC emacs-lisp
;; Don't bring up key recipient dialogue.
(require 'epa-file)
(setq epa-file-select-keys 1)
(setq epa-file-encrypt-to '("<daniil.rose@member.fsf.org>"))

;; Increase the password cache expiry time, technically doesn't do anything for GPG2
(setq password-cache-expiry (* 60 15))

;; Fix EasyPG error.
;; From https://colinxy.github.io/software-installation/2016/09/24/emacs25-easypg-issue.html.
(defvar epa-pinentry-mode)
(setq epa-pinentry-mode 'loopback)
#+END_SRC

Oh, and why use those GUI popups for the password?

#+BEGIN_SRC emacs-lisp
  (use-package pinentry)
  (setf epg-pinentry-mode 'loopback)
  (defun pinentry-emacs (desc prompt ok error)
     (let ((str (read-passwd
                 (concat (replace-regexp-in-string "%22" "\""
                                                   (replace-regexp-in-string "%0A" "\n" desc)) prompt ": "))))
       str))
#+END_SRC

* Advanced Configuration
** Vertico & Friends
I've recently been trying out ~vertico.el~, because it seems
faster/more efficient than Ivy/Company, and because it's trendy right
now :D.

After a little while of playing with Vertico, I definitely will keep
it. It is significantly faster than Ivy, and does what I want a
completion engine to do!

*** Vertico
The minimal completion engine.

#+BEGIN_SRC emacs-lisp

** Email
Now, let's add mu4e. I keep this account file in a different location,
but you can easily learn to do this with the great Reddit post "mu4e
for Dummies." I keep my settings in a directory in ~.emacs.d~ called
~mu4e~.

I am currently in the process of attempting to convert from smtpmail

Emacs slow downs when sending mail (which in combination with pgtk and

* Language Support
Plenty of features and things to improve here, from adding languages to
flycheck to lsp.

** Convenient Features
Things that are really nice to have, but I'm not sure which category they would go in.

Format on save is awesome!

#+BEGIN_SRC emacs-lisp

Compile various code and scroll output.

#+BEGIN_SRC emacs-lisp

#+END_SRC

Makes code easier to read, and specifically on these, as I do not want rainbow to conflict with parinfer in Lisp

LSP is quite amazing, and has come /so/ far in Emacs! DAP is also

** Languages
The meat and potatoes of this section. Includes all the above
mentioned languages! Technically, my "four" most used are Rust,
Python, C/C++, and Lisp (which mostly includes Hy and Elisp). The rest
of the things here are either for fun, or just convenient to
have. I've been spending more time improving my Computer
Science/Critical Thinking skills instead of focusing on languages.

Now that language list isn't particularly true. I have recently been
working at understanding web languages, and although they used to
enfuriate me, I have a new-found appreciate and understanding for
them! They are here too of course now. Still doesn't mean I'll switch
to being a web developer any time soon :P

Sadly IntelliJ and Android Studio are just too good for
Java/Kotlin. I'll stick with the proper tools for those languages, but
with Emacs keybindings of course :D

*** Rust
Crustacean for life! Rust is a great language, but is taking it's time
to completely be accepted. Most of my work nowadays is done in Rust.

Another interesting thing I recently found is Cargo mode, a minor mode
