-#+TITLE: My Literate GNU Emacs Config
-#+AUTHOR: Marius Peter
-#+DATE: <2020-07-23 Thu>
-#+EMAIL: blendoit@gmail.com

-#+LATEX: \begin{abstract}
-GNU Emacs is most often used as a text editor. The utmost level of
-customization is afforded by enabling the user to rewrite \textit{any} part of
-the source code and observe the editor's modified behaviour in real time. Since
-its inception in 1984, GNU Emacs has grown to be much more than a
-full-featured, high-productivity text editor---new \textit{modes} have been
-written to interact with hundreds of file formats, including \texttt{.txt},
-\texttt{.pdf}, \texttt{.jpg}, \texttt{.csv}, and \texttt{.zip} just to name a
-few. This configuration file itself was written in \textit{Org mode}, a
-collection of functions enabling the harmonious mixing of code and comments in
-view of publication: this is the endgame of \textit{literate programming}.
-#+LATEX: \end{abstract}
-
-* Introduction
-
-The following sections were laid out very deliberately. When we start Emacs,
-Emacs Lisp source code blocks contained in this document are evaluated
-sequentially---our editing environment is constructed in real time as we
-execute the blocks in order. For instance, we only begin loading packages once
-we ensured ~use-package~ is working properly.
-
-Customizing Emacs goes far, far beyond this document---feel free to experiment
-and discover.
-
-- ~C-h f~ describe function
-- ~C-h v~ describe variable
-- ~C-h k~ describe key
-
-These three commands will attempt to describe the element currently under our
-cursor, however you can start typing to search for another symbol.
-
-* TODO First-time setup
-
-Spacemacs-like dialog for default settings.
-
-#+NAME: first-setup
-# #+BEGIN_SRC emacs-lisp
-#     ;; Prompt enterprise or personal install. Create file in .emacs.d/ on Linux,
-#     ;; AppData/ on Windows. Ask user for details and preferred bindings.
-#
-#   ; Check if .emacs.d exists
-#
-#   ; If it does, warn user
-#
-#   ; Copy init-bootstrap.el from USB to where operating systems expects init.el
-#
-#   ;;   (defun blendoit/first-time-setup-windows-nt ()
-#   ;;     "Execute the first-time setup on MS Windows.
-#   ;; If no `.emacs.d/' config exists on local system, copy

-# #+END_SRC
-
-** File system paths
-
-In this subsection, we tell Emacs about relevant paths to resources.
-
-On my MS Windows machine, I add the path to Portable Git.[fn::Download from
-https://git-scm.com/download/win]
-
-#+BEGIN_SRC emacs-lisp
-  (when (string-equal system-type "windows-nt")
-    (add-to-list 'exec-path "C:/Users/marius.peter/PortableGit/bin/"))
-#+END_SRC
-
-* Early setup
-
-** Garbage collection
-
-First, we increase the RAM threshold beyond which the garbage collector is
-activated.
-
-#+NAME: garbage-collection
-#+BEGIN_SRC emacs-lisp
-(setq gc-cons-threshold 100000000)
-#+END_SRC
-
-** Profiling --- start
-
-We start the profiler now , and will interrupt it in Section [[Profiling ---
-stop]]. We will then present profiling report in Section [[Profiling --- report]].
-
-#+NAME: profiler-start
-#+BEGIN_SRC emacs-lisp
-; (profiler-start)
-#+END_SRC
-
-** Emacs client
-
-Makes opening emacs faster for following instances.
-
-#+NAME: emacs-client
-#+BEGIN_SRC emacs-lisp
-; (setq initial-buffer-choice (lambda () (get-buffer "*dashboard*")))
-#+END_SRC
-
-** Custom file
-
-Load settings created automatically by GNU Emacs Custom. (For example, any
-clickable option/toggle is saved here.) Useful for fooling around with M-x
-customize-group <package>.
-
-user-emacs-directory
-
-#+NAME: custom-file-location
-#+BEGIN_SRC emacs-lisp
-  (setq custom-file (concat user-emacs-directory "init-custom.el"))
-  (load custom-file)
-#+END_SRC
-
-** Customization shortcuts
-
-We begin by defining a user shortcut to this very file. We load this as early as
-possible, this facilitates debugging.
-
-#+NAME: shortcut-config
-#+BEGIN_SRC emacs-lisp
-  (defun my/find-literate-config ()
-    "Jump to this very file."
-    (interactive)
-    (find-file my/literate-config))
-
-  (global-set-key (kbd "C-c c") 'my/find-literate-config)
-#+END_SRC
-
-Now, different shortcuts for other customization actions:
-
-#+NAME: shortcuts-customization
-#+BEGIN_SRC emacs-lisp
-  (global-set-key (kbd "C-c v") 'customize-variable)
-  (global-set-key (kbd "C-c f") 'customize-face)
-#+END_SRC
-
-** Backups
-
-Backups are so important that they should be described right after the shortcut
-to this file.
-
-#+BEGIN_SRC emacs-lisp
-  (setq backup-directory-alist `((".*" . ,temporary-file-directory))
-  auto-save-file-name-transforms `((".*" ,temporary-file-directory t))
-      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    ; and how many of the old
-      )
-#+END_SRC
-
-** Initial and default frames
-
-We set the dimensions of the inital and default frames.
-
-#+BEGIN_SRC emacs-lisp
-  (add-to-list 'default-frame-alist '(width  . 100))
-  (add-to-list 'default-frame-alist '(height . 50))
-
-  (add-to-list 'initial-frame-alist '(width  . 100))
-  (add-to-list 'initial-frame-alist '(height . 50))
-#+END_SRC
-
-*** GNU/Linux
-
-These settings affect the first and subsequent frames spawned by Emacs in
-GNU/Linux. Frame transparency increases when focus is lost.
-
-#+BEGIN_SRC emacs-lisp
-  (when (and (display-graphic-p) (string-equal system-type "gnu/linux"))
-    (set-frame-parameter (selected-frame) 'alpha '(90 . 50))
-    (add-to-list 'default-frame-alist '(alpha . (90 . 50))))
-#+END_SRC
-
-** Secrets
-
-The code contained in the =secrets.org= file is loaded by Emacs, but not
-rendered in this PDF for the sake of privacy. It contains individually
-identifying information such as names and e-mail addresses, which are used to
-populate Org templates (Section [[~org-mode~]]).
-
-You need to create this =secrets.org= file, as it is ignored by =git= by
-default.
-
-#+BEGIN_SRC emacs-lisp
-  (org-babel-load-file "~/.emacs.d/blendoit/secrets.org")
-#+END_SRC
-
-* Global key bindings
-
-The following bindings strive to further enhance CUA mode.[fn::Common User
-Access. This is a term coined by IBM which has influenced user navigation cues
-on all modern desktop OSes. From IBM's CUA, we get the =Ctrl-v= and =Ctrl-v=
-keyboard shortcuts.]
-
-#+BEGIN_SRC emacs-lisp
- (cua-mode)
-#+END_SRC
-
-
-** Keyboard navigation
-
-#+BEGIN_SRC emacs-lisp
-  (global-set-key (kbd "C-`") 'delete-other-windows)
-#+END_SRC
-
-*** Saving a file
-
-#+BEGIN_SRC emacs-lisp
-  (global-set-key (kbd "C-s") 'save-buffer)
-#+END_SRC
-
-*** Opening a file
-
-#+BEGIN_SRC emacs-lisp
-  (global-set-key (kbd "C-o") 'find-file)
-#+END_SRC
-
-*** Opening a recently visited file
-
-#+BEGIN_SRC emacs-lisp
-  (global-set-key (kbd "C-r") 'counsel-recentf)
-#+END_SRC
-
-*** Locating a file
-
-#+BEGIN_SRC emacs-lisp
-  (global-set-key (kbd "C-c l") 'counsel-locate)
-#+END_SRC
-
-*** Closing window and quitting Emacs
-
-#+BEGIN_SRC emacs-lisp
-  (defun my/delete-window-or-previous-buffer ()
-    "Delete window; if sole window, previous buffer."
-     (interactive)
-     (if (> (length (window-list)) 1)
-       (delete-window)
-       (previous-buffer)))
-#+END_SRC
-
-The following bindings lead to more natural exit behaviors.
-
-#+BEGIN_SRC emacs-lisp
-(global-set-key (kbd "C-w") 'my/delete-window-or-previous-buffer)
-(global-set-key (kbd "C-q") 'save-buffers-kill-terminal)
-#+END_SRC
-
-** Mouse zoom
-
-The typical binding on both GNU/Linux and MS Windows is adequate here: ~C-=~ to
-zoom in, ~C--~ to zoom out.
-
-It seems that starting with Emacs 27.1, Control + mousewheel works.
-
-#+BEGIN_SRC emacs-lisp
-(global-set-key (kbd "C--") 'text-scale-decrease)
-(global-set-key (kbd "C-=") 'text-scale-increase)
-(global-set-key (kbd "C-+") 'text-scale-increase)
-#+END_SRC
-
-* Packages
-
-Packages are collections of =.el= files providing added functionality to Emacs.
-
-** Meta
-
-How do we bootstrap packages? First, let's figure out:
-
-1. Where we get our packages from
-2. How we upgrade packages
-3. How we ensure our required packages are installed
-
-*** Package archives
-
-List of package archives.
-
-#+NAME: package-archives
-#+BEGIN_SRC emacs-lisp
-  (require 'package)
-  (add-to-list 'package-archives '("melpa" . "https://melpa.org/packages/") t)
-  (add-to-list 'package-archives '("org" . "https://orgmode.org/elpa/") t)
-  (package-initialize)
-#+END_SRC
-
-*** TODO Convenient package update
-
-One-function rollup of upgradeable package tagging, download and lazy install.
-
-#+BEGIN_SRC emacs-lisp
-
-#+END_SRC
-
-*** ~use-package~
-
-We ensure =use-package= is installed, as well as all packages described in this
-configuration file.
-
-#+BEGIN_SRC emacs-lisp
-  (unless (package-installed-p 'use-package)
-    (package-refresh-contents)
-    (package-install 'use-package)
-    (eval-when-compile (require 'use-package)))
-  (setq use-package-always-ensure t)
-(require 'use-package)
-(require 'bind-key)
-#+END_SRC
-
-** ~org-mode~
-
-Phew, I can finally introduce Org mode! I am so *excited*.
-
-Org mode replaces aword processor, a presentation creator, and a spreadsheet
-editor. IMHO, the spreadsheet ability captures more than 80% use cases wherein
-one wishes to include a table in a text document destined for physical
-publication. (It is clear that Excel spreadsheets are /not/ destined for
-physical publication---simply attempt to print an Excel spreadsheet with the
-default settings.)  In my opinion, Org mode matches all /useful/ features of
-the Microsoft Office suite 1-to-1.
-
-What follows are customizations designed to make Org mode behave more like
-Microsoft Word. The end goal is, once again, to draw as many new users to Emacs
-as possible!
-
-*** Basic customization
-
-Org base directory is in user home on GNU/Linux, or in =AppData= in MS Windows.
-
-#+NAME: org-basic
-#+BEGIN_SRC emacs-lisp
-  (setq org-directory (concat user-emacs-directory "~/org"))
-#+END_SRC
-
-First, we hide markup symbols for *bold*, /italic/, _underlined_ and
-+strikethrough+ text, and ensure our document appears indented upon
-loading:[fn::It /appears/ indented, but the underlying plaintext file does not
-contain tab characters!]
-
-For the time being, I will in fact display emphasis markers, because hiding
-them corrupts tables.
-
-#+NAME: org-basic
-#+BEGIN_SRC emacs-lisp
-  (setq org-hide-emphasis-markers nil)
-  (setq org-startup-indented t)
-#+END_SRC
-
-*** Languages executable in smart documents
-
-The following languages can be written inside =SRC= blocks, in view of being
-executed by the Org Babel backend.
-
-#+BEGIN_SRC emacs-lisp
-  (setq org-babel-load-languages
-        '((shell . t)
-          (python . t)
-          (plantuml . t)
-          (emacs-lisp . t)
-          (awk . t)
-          (ledger . t)
-          (gnuplot . t)
-          (latex . t)))
-#+END_SRC
-
-*** Prevent or warn on invisible edits
-
-#+BEGIN_SRC emacs-lisp
-(setq org-catch-invisible-edits t)
-#+END_SRC
-
-*** Agenda
-
-The agenda displays a chronological list of headings across all agenda files
-for which the heading or body contain a matching =org-time-stamp=.[fn::An
-=org-time-stamp= can be inserted with ~C-c .~ (period)]
-
-#+BEGIN_SRC emacs-lisp
-  (global-set-key (kbd "C-c a") 'org-agenda-list)
-
-  (defun my/find-diary-file ()
-    "Load `org-agenda-diary-file'."
-    (interactive)
-    (find-file org-agenda-diary-file))
-
-  (global-set-key (kbd "C-c d") 'my/find-diary-file)
-#+END_SRC
-
-*** Timestamps
-
-More literary timestamps are exported to LaTeX using the following custom
-format:
-
-#+BEGIN_SRC emacs-lisp
-  (setq org-time-stamp-custom-formats
-    '("%d %b, %Y (%a)" . "%d %b, %Y (%a), at %H:%M"))
-#+END_SRC
-
-*** LaTeX export
-
-We'll be compiling our documents with LuaTeX. This will afford us some
-future-proofing, since it was designated as the successor to pdfTeX by the
-latter's creators.
-
-First, we define the command executed when an Org file is exported to
-LaTeX. We'll use =latexmk=, the Perl script which automagically runs binaries
-related to LaTeX in the correct order and the right amount of times.
-
-Options and why we need them:
-- ~-shell-excape~ :: required by minted to color source blocks
-- ~-pdflatex=lualatex~ :: we use lualatex to generate our PDF
-- ~-interaction=nonstopmode~ :: go as far as possible without prompting user
-  for input
-
-#+BEGIN_SRC emacs-lisp
-  (setq org-latex-pdf-process
-        '("latexmk -pdf -f \
-  -pdflatex=lualatex -shell-escape \
-  -interaction=nonstopmode -outdir=%o %f"))
-#+END_SRC
-
-We customize the format for org time stamps to make them appear monospaced in
-our exported LaTeX documents. This makes them visually distinguishable from
-body text.
-
-#+BEGIN_SRC emacs-lisp
-  (setq org-latex-active-timestamp-format
-        "\\texttt{%s}")
-  (setq org-latex-inactive-timestamp-format
-        "\\texttt{%s}")
-#+END_SRC
-
-The following packages are loaded for every time we export to LaTeX.
-
-#+BEGIN_SRC emacs-lisp
-  (setq org-latex-packages-alist
-     '(("AUTO" "polyglossia" t
-        ("xelatex" "lualatex"))
-       ("AUTO" "babel" t
-        ("pdflatex"))
-       ("" "booktabs" t
-        ("pdflatex"))
-       ("table,svgnames" "xcolor" t
-        ("pdflatex"))))
-#+END_SRC
-
-Little bonus for GNU/Linux users: syntax highlighting for source code blocks in
-LaTeX exports.
-
-#+BEGIN_SRC emacs-lisp
-  (when (string-equal system-type "gnu/linux")
-    (add-to-list 'org-latex-packages-alist '("AUTO" "minted" t
-                                             ("pdflatex" "lualatex")))
-    (setq org-latex-listings 'minted)
-     (setq org-latex-minted-options
-       '(("style" "friendly") ())))
-#+END_SRC
-
-Now, we set the files to be deleted when a LaTeX \rightarrow PDF compilation
-occurs. We only care about two files, in the end: the Org mode file for
-edition, and the PDF for distribution.
-
-#+BEGIN_SRC emacs-lisp
-  (setq org-latex-logfiles-extensions
-        '("aux" "bcf" "blg" "fdb_latexmk"
-          "fls" "figlist" "idx" "log" "nav"
-          "out" "ptc" "run.xml" "snm" "toc" "vrb" "xdv"
-          "tex" "lot" "lof"))
-#+END_SRC
-
-By default, Org agenda inserts diary entries as the first under the selected
-date. It is preferable to insert entries in the order that they were recorded,
-i.e. chronologically.
-
-#+BEGIN_SRC emacs-lisp
- (setq org-agenda-insert-diary-strategy 'date-tree-last)
-#+END_SRC
-
-What follows are the document class structures that can be exported in LaTeX.
-
-#+BEGIN_SRC emacs-lisp
- (setq org-latex-classes

-#+END_SRC
-
-By default, body text can immediately follow the table of contents. It is
-however cleaner to separate table of contents with the rest of the work.
-
-#+BEGIN_SRC emacs-lisp

-
-
-
-The following makes =TODO= items appear red and =CLOSED= items appear green in
-Org's LaTeX exports. Very stylish, much flair!
-

-by using =TAB= (next field) and =SHIFT-TAB= (previous field).
-
-For instance: Typing =src= then pressing =TAB= will expand the keyword to the
-following text:

-** My light and dark themes
-
-A highly legible unambiguous and thoughtful theme.
-
-*** Colors
-
-The default face is a black foreground on a white background, this matches MS
-Word. We are striving for a simple, intuitive color scheme.
-
-Most of the visual cues derived from color are identical in both light and dark
-themes (Table [[theme-color-1]]).

-*** Cursors
-
-In order to imitate other modern text editors, we resort to a blinking bar
-cursor. We choose red, the most captivating color, because the cursor is
-arguably the region on our screen:
-
-1. most often looked at;
-2. most often searched when lost.
-
-In files containing only ~fixed-pitch~ fonts (i.e. files containing only code),
-the cursor becomes a high-visibility box.
-
-In files containing a mix of ~variable-pitch~ and ~fixed-pitch~ fonts, the
-cursor is a more MS Word-like bar.

-*** Faces
-
-- ~default~: Hack
-  - Legible, modern monospace font
-  - Strict, sharp, uncompromising
-- ~fixed-pitch~: Hack
-- ~variable-pitch~: Liberation Sans
-  - Libre alternative to Arial
-- ~org-block~: Hermit
-  - Slightly wider than Hack
-  - More opinionated shapes
-  - Very legible parentheses
-
-**** ~variable-pitch-mode~

-We use ~variable-pitch-mode~ for appropriate modes.

-* Late setup
-
-At this point, our editor is almost ready to run. Phew! All that's left to do
-is to interrupt our profiling activities, and smartly store the result of our
-profiling.

-* Conclusion
-
-In this configuration file, we described a series of customization steps taken
-to make Emacs more palatable to modern IDE users.
