* Introduction
:PROPERTIES:
:CUSTOM_ID: Introduction7gzhel6184j0
:END:
After a couple of years using Spacemacs and a failed attempt at
switching to DoomEmacs, I’m finally switching back to a vanilla
configuration! Why? Because I got tired of the framework getting in my
way when I wanted to do stuff. I’m sure this is more applicable to
Spacemacs than DoomEmacs since the latter has nice macros written to
easily add new packages and configure them, such as ~package!~, ~after!~,
and others. But ultimately, I wanted to have a system I designed
entirely, with the keybinds I want, the packages I want.

Aso, why Emacs? You know this famous quote:
#+begin_quote
Emacs is a great operating system, it just lacks a good text editor.
#+end_quote

It’s actually pretty true in my opinion. Emacs is basically a Lisp
machine with a default text editor, programmed with EmacsLisp, a
general-purpose programming language. Therefore, if you want to do
something in Emacs, with enough Elisp you can do it --- if it’s not in
Emacs already, that is.

* A Warning Before You Proceed
:PROPERTIES:
:CUSTOM_ID: A-Warning-Before-You-Proceed-mgyar9i0ucj0
:header-args:emacs-lisp: :tangle no
:END:
This configuration makes heavy use of the [[https://orgmode.org/manual/Noweb-Reference-Syntax.html][noweb]] syntax. This means if
you encounter some code that looks ~<<like-this>>~, org-mode will
replace this snippet with another code snippet declared elsewhere in
my configuration. If you see some code that looks ~<<like-this()>>~,
some generating code will run and replace this piece of text with the
text generated. A quick example:
#+begin_src elisp
(defun hello ()
  <<generate-docstring()>>
  <<print-hello>>)
#+end_src

Will instead appear as
#+begin_src emacs-lisp :noweb yes
(defun hello ()
  <<generate-docstring()>>
  <<print-hello>>)
#+end_src

This is because I have the block of code below named
~generate-docstring~ which generates an output, which replaces its noweb
tag. You can recognize noweb snippets generating code with the
parenthesis. Often, such blocks aren’t visible in my HTML exports, but
you can still see them if you open the actual org source file.
#+name: generate-docstring
#+begin_src emacs-lisp
(concat "\""
        "Print \\\"Hello World!\\\" in the minibuffer."
        "\"")
#+end_src

On the other hand, noweb snippets without parenthesis simply replace
the snippet with the equivalent named code block. For instance the one
below is named ~print-hello~ and is placed as-is in the target source
block.
#+name: print-hello
#+begin_src emacs-lisp
(message "Hello World!")
#+end_src

The early init file is the file loaded before anything else in
Emacs. This is where I put some options in order to disable as quickly
as possible some built-in features of Emacs before they can be even
loaded, speeding Emacs up a bit.

** Emacs Behavior
:PROPERTIES:
:CUSTOM_ID: Basic-configuration-Emacs-Behavior6gbiel6184j0
:END:
*** Editing Text in Emacs
:PROPERTIES:
:CUSTOM_ID: Basic-configuration-Emacs-Behavior-Editing-Text-in-Emacsy2fiel6184j0
:END:
I *never* want to keep trailing spaces in my files, which is why I’m
doing this:
#+begin_src emacs-lisp
(add-hook 'before-save-hook #'whitespace-cleanup)
#+end_src

I don’t understand why some people add two spaces behind a full stop,
I sure don’t. Let’s tell Emacs.
#+begin_src emacs-lisp
(setq-default sentence-end-double-space nil)
#+end_src

There is a minor mode in Emacs which allows to have a finer way of
jumping from word to word: ~global-subword-mode~. It detects if what
Emacs usually considers a word can be understood as several words, as
in camelCase words, and allows us to jump words on this finer level.
#+begin_src emacs-lisp
(global-subword-mode 1)
#+end_src

Changing half my screen each time my cursor goes too high or too low
is not exactly ideal. Fortunately, if we set ~scroll-conservatively~
high enough we can have the cursor stay on top or at the bottom of the
screen while the text scrolls progressively.
#+begin_src emacs-lisp
(setq scroll-conservatively 1000)
#+end_src

Lastly, I want the default mode for Emacs to be Emacs Lisp.
#+begin_src emacs-lisp
(setq-default initial-major-mode 'emacs-lisp-mode)
#+end_src

**** Indentation
:PROPERTIES:
:CUSTOM_ID: Basic-configuration-Emacs-Behavior-Editing-Text-in-Emacs-Indentationauiiel6184j0
:END:
I don’t like tabs. They rarely look good, and if I need it I can
almost always tell Emacs to use them through a ~.dir-locals.el~ file or
through the config file of my code formatter. So by default, let’s
disable them:
#+begin_src emacs-lisp
(setq-default indent-tabs-mode nil)
(add-hook 'prog-mode-hook (lambda () (setq indent-tabs-mode nil)))
#+end_src

Just to go on a little tangent here: I don’t exactly /hate/ tabs, but I
find them really annoying when your text editor knows only them. Sure,
for indentation they work great, and they allow different people
getting different settings in their text editor depending on their
preferred tastes —some may prefer 2 spaces tabs, some may prefer 4
spaces tabs, some deranged people prefer 8 spaces tabs, and some
monsters prefer 3!

But the thing is, once you indented your code and then you need
alignment, tabs don’t work anymore! Or they may on *your* text editor
but not on your coworker’s! (He’s the one using 3 spaces tabs by the
way).

So, is the answer to use spaces instead of tabs, and screw peoples’
preferences in terms of tabs width? No, I say the answer is more
moderate than that, and it might frighten or anger some of you at
first: use both spaces and tabs. Now, before you lynch me on the main
avenue in front of everyone, let me tell you absolutely no one should
ever be mixing spaces and tabs for indentation, that would be
absolutely terrible and would bring the worst of both worlds. What’s
the best of both worlds then?
#+begin_center
/Tabs for indentation/

/Spaces for alignment/
#+end_center

I haven’t found a way to automate that in Emacs yet aside from
formatters’ config file, and tabs look bat in EmacsLisp anyway, so
I’ll stick with spaces by default and change it where needed.

*** Programming Modes
:PROPERTIES:
:CUSTOM_ID: Basic-configuration-Emacs-Behavior-Programming-Modesfnmiel6184j0
:END:
First off, my definition of what makes a “programming mode” doesn’t exactly
fit mine, so on top of ~prog-mode~, let’s add a few other modes.
#+name: line-number-modes-table
| Modes      |
|------------|
| prog-mode  |
| latex-mode |

#+name: prog-modes-gen
#+header: :cache yes :exports none :tangle no
#+begin_src emacs-lisp :var modes=line-number-modes-table
(mapconcat (lambda (mode) (format "%s-hook" (car mode)))
           modes
           " ")
#+end_src

**** Line Number
:PROPERTIES:
:CUSTOM_ID: Basic-configuration-Emacs-Behavior-Programming-Modes-Line-Numbermcqiel6184j0
:END:
Since version 26, Emacs has a built-in capacity of displaying line
numbers on the left-side of the buffer. This is a fantastic feature
that should actually be the default for all programming modes.

#+begin_src emacs-lisp
(dolist (mode '(<<prog-modes-gen()>>))
  (add-hook mode #'display-line-numbers-mode))
#+end_src

**** Folding code
:PROPERTIES:
:CUSTOM_ID: Basic-configuration-Emacs-Behavior-Programming-Modes-Folding-code16uiel6184j0
:END:
Most programming languages can usually have their code folded, be it
code between curly braces, chunks of comments or code on another level
of indentation (Python, why…?). The minor-mode that enables that is
~hs-minor-mode~, let’s enable it for all of these programming modes:
#+begin_src emacs-lisp
(dolist (mode '(<<prog-modes-gen()>>))
  (add-hook mode #'hs-minor-mode))
#+end_src

*** Stay Clean, Emacs!
:PROPERTIES:
:CUSTOM_ID: Basic-configuration-Emacs-Behavior-Stay-Clean-Emacs7wxiel6184j0
:END:
As nice as Emacs is, it isn’t very polite or clean by default: open a
file, and it will create backup files in the same directory. But then,
when you open your directory with your favorite file manager and see
almost all of your files duplicated with a =~= appended to the filename,
it looks really uncomfortable! This is why I prefer to tell Emacs to
keep its backup files to itself in a directory it only will access.
#+begin_src emacs-lisp
(setq backup-directory-alist `(("." . ,(expand-file-name ".tmp/backups/"
                                                         user-emacs-directory))))
#+end_src

It also loves to litter its ~init.el~ with custom variables here and
there, but the thing is: I regenerate my ~init.el~ each time I tangle
this file! How can I keep Emacs from adding stuff that will be almost
immediately lost? Did someone say /custom file/?
#+begin_src emacs-lisp
(setq-default custom-file (expand-file-name ".custom.el" user-emacs-directory))
(when (file-exists-p custom-file) ; Don’t forget to load it, we still need it
  (load custom-file))
#+end_src

If we delete a file, we want it moved to the trash, not simply deleted.
#+begin_src emacs-lisp
(setq delete-by-moving-to-trash t)
#+end_src

Finally, the scatch buffer always has some message at its beginning, I
don’t want it!
#+begin_src emacs-lisp
(setq-default initial-scratch-message nil)
#+end_src

*** Stay Polite, Emacs!
:PROPERTIES:
:CUSTOM_ID: Basic-configuration-Emacs-Behavior-Stay-Polite-Emacszp1jel6184j0
:END:
When asking for our opinion on something, Emacs loves asking us to
answer by “yes” or “no”, but *in full*! That’s very rude! Fortunately,
we can fix this.
#+begin_src emacs-lisp
(defalias 'yes-or-no-p 'y-or-n-p)
#+end_src

This will make Emacs ask us for either hitting the ~y~ key for “yes”, or
the ~n~ key for “no”. Much more polite!

It is also very impolite to keep a certain version of a file in its
buffer when said file has changed on disk. Let’s change this behavior:
#+begin_src emacs-lisp
(global-auto-revert-mode 1)
#+end_src

Much more polite! Note that if the buffer is modified and its changes
haven’t been saved, it will not automatically revert the buffer and
your unsaved changes won’t be lost. Very polite!

*** Misc
:PROPERTIES:
:CUSTOM_ID: Basic-configuration-Emacs-Behavior-Misc9j5jel6184j0
:END:
Let’s raise Emacs undo memory to 10MB, and make Emacs auto-save our
files by default.
#+begin_src emacs-lisp
(setq undo-limit        100000000
      auto-save-default t)
#+end_src

#+begin_src emacs-lisp
(setq window-combination-resize t) ; take new window space from all other windows
#+end_src

** Personal Information
:PROPERTIES:
:CUSTOM_ID: Basic-configuration-Personal-Informationi59jel6184j0
:END:
Emacs needs to know its master! For various reasons by the way, some
packages rely of these variables to know who it is talking to or
dealing with, such as ~mu4e~ which will guess who you are if you haven’t
set it up correctly.
#+begin_src emacs-lisp
(setq user-full-name       "Lucien Cartier-Tilet"
      user-real-login-name "Lucien Cartier-Tilet"
      user-login-name      "phundrak"
      user-mail-address    "lucien@phundrak.com")
#+end_src

** Visual Configuration
:PROPERTIES:
:CUSTOM_ID: Basic-configuration-Visual-Configurationzvcjel6184j0
:END:
The first visual setting in this section will activate the visible
bell. What it does is I get a visual feedback each time I do something
Emacs doesn’t agree with, like tring to go up a line when I’m already
at the top of the buffer.
#+begin_src emacs-lisp
(setq visible-bell t)
#+end_src

It is nicer to see a cursor cover the actual space of a character.
#+begin_src emacs-lisp
(setq x-stretch-cursor t)
#+end_src

When text is ellipsed, I want the ellipsis marker to be a single
character of three dots. Let’s make it so:
#+begin_src emacs-lisp
(setq truncate-string-ellipsis "…")
#+end_src

Thanks to [[https://github.com/TheVaffel/emacs][this fork]] of Emacs, it is now possible to set some
transparency to the background of Emacs only and not to the entire
frame.
#+begin_src emacs-lisp
(add-hook 'server-after-make-frame-hook (lambda ()
                                          (set-frame-parameter (selected-frame)
                                                               'alpha-background 0.7)))
#+end_src

*** Modeline Modules
:PROPERTIES:
:CUSTOM_ID: Basic-configuration-Visual-Configuration-Modeline-Modules9kgjel6184j0
:END:
I sometimes use Emacs in fullscreen, meaning my usual taskbar will be
hidden. This is why I want the current date and time to be displayed,
in an ISO-8601 style, although not exactly ISO-8601 (this is the best
time format, fight me).
#+begin_src emacs-lisp
(setq display-time-format "%Y-%m-%d %H:%M")
(display-time-mode 1) ; display time in modeline
#+end_src

Something my taskbar doesn’t have is a battery indicator. However, I
want it enabled only if I am on a laptop or if a battery is available.
#+begin_src emacs-lisp
(let ((battery-str (battery)))
  (unless (or (equal "Battery status not available" battery-str)
              (string-match-p (regexp-quote "N/A") battery-str))
    (display-battery-mode 1)))
#+end_src

This isn’t a modeline module per se, but we have an indicator of the
current line in Emacs. And although it is useful, I also often wish to
know which column I’m on. This can be activated like so:
#+begin_src emacs-lisp
(column-number-mode)
#+end_src

The following code is, as will several chunks of code in this config,
borrowed from [[https://tecosaur.github.io/emacs-config/#theme-modeline][TEC’s configuration]]. It hides the encoding information
of the file if the file itself is a regular UTF-8 file with ~\n~ line
ending. Be aware the ~doom-modeline-buffer-encoding~ variable is usabel
here only because I use the Doom modeline as seen below.
#+begin_src emacs-lisp
(defun modeline-contitional-buffer-encoding ()
  "Hide \"LF UTF-8\" in modeline.

It is expected of files to be encoded with LF UTF-8, so only show
the encoding in the modeline if the encoding is worth notifying
the user."
  (setq-local doom-modeline-buffer-encoding
              (unless (and (memq (plist-get (coding-system-plist buffer-file-coding-system) :category)
                                 '(coding-category-undecided coding-category-utf-8))
                           (not (memq (coding-system-eol-type buffer-file-coding-system) '(1 2))))
                t)))
#+end_src

Now, let’s automate the call to this function in order to apply the
modifications to the modeline each time we open a new file.
#+begin_src emacs-lisp
(add-hook 'after-change-major-mode-hook #'modeline-contitional-buffer-encoding)
#+end_src

*** Fonts

#+begin_src emacs-lisp

** Nice Macros From Doom-Emacs
:PROPERTIES:
:CUSTOM_ID: Basic-configuration-Nice-Macros-From-Doom-Emacsgyrjel6184j0
:END:
Doom-Emacs has some really nice macros that can come in really handy,
but since I prefer to rely on my own configuration, I’ll instead just
copy their code here. First we get the ~after!~ macro:
#+begin_src emacs-lisp
(require 'cl-lib)
(defmacro after! (package &rest body)
  "Evaluate BODY after PACKAGE have loaded.

PACKAGE is a symbol or list of them. These are package names, not modes,
functions or variables. It can be:

- An unquoted package symbol (the name of a package)
    (after! helm BODY...)
- An unquoted list of package symbols (i.e. BODY is evaluated once both magit
  and git-gutter have loaded)
    (after! (magit git-gutter) BODY...)
- An unquoted, nested list of compound package lists, using any combination of
  :or/:any and :and/:all
    (after! (:or package-a package-b ...)  BODY...)
    (after! (:and package-a package-b ...) BODY...)
    (after! (:and package-a (:or package-b package-c) ...) BODY...)
  Without :or/:any/:and/:all, :and/:all are implied.

This is a wrapper around `eval-after-load' that:

1. Suppresses warnings for disabled packages at compile-time
2. Supports compound package statements (see below)
3. Prevents eager expansion pulling in autoloaded macros all at once"

** Screenshots
:PROPERTIES:
:CUSTOM_ID: Custom-Elisp-Screenshots-l9bkib013aj0
:END:
Since Emacs27, it is possible for Emacs to take screenshots of itself
in various formats. I’m mainly interested by the SVG and PNG format,
so I’ll only write functions for these. It isn’t really redundant with
the ~screenshot.el~ package used [[#Packages-Configuration-Applications-Screenshot96d1fl6184j0][here]] since these functions take a
screenshot of Emacs as a whole rather than of a code snippet.

First, we have a general function which is a slight modification of
the function shared by Alphapapa in [[https://www.reddit.com/r/emacs/comments/idz35e/emacs_27_can_take_svg_screenshots_of_itself/g2c2c6y/][this Reddit comment]]. It has been
modified so it is possible to pass the function an argument for the
format the screenshot will be taken as, and if ~type~ is ~nil~ the user
can still chose it.
#+begin_src emacs-lisp
(defun self-screenshot (&optional type)
  "Save a screenshot of type TYPE of the current Emacs frame.
As shown by the function `', type can weild the value `svg',
`png', `pdf'.

This function will output in /tmp a file beginning with \"Emacs\"
and ending with the extension of the requested TYPE."
  (interactive)
  (let* ((type (if type type
                 (intern (completing-read "Screenshot Type: "
                                          '(png svg pdf postscript)))))
         (extension (pcase type
                      ('png        ".png")
                      ('svg        ".svg")
                      ('pdf        ".pdf")
                      ('postscript ".ps")
                      (otherwise (error "Cannot export screenshot of type %s" otherwise))))
         (filename (make-temp-file "Emacs-" nil extension))
         (data     (x-export-frames nil type)))
    (with-temp-file filename
      (insert data))
    (kill-new filename)
    (message filename)))
#+end_src

I used this function to take the screenshots you can see in this
document.

** Handle new windows
:PROPERTIES:

One function I find missing regarding ~add-to-list~ is ~add-all-to-list~
so I can add multiple elements to a list at once. Instead, with
vanilla Emacs, I have to repeatedly call ~add-to-list~. That’s not very
clean. Let’s declare this missing function:
#+begin_src emacs-lisp
(defun add-all-to-list (list-var elements &optional append compare-fn)
  "Add ELEMENTS to the value of LIST-VAR if it isn’t there yet.

ELEMENTS is a list of values. For documentation on the variables
APPEND and COMPARE-FN, see `add-to-list'."
  (let (return)
    (dolist (elt elements return)
      (setq return (add-to-list list-var elt append compare-fn)))))

** Repositories
:PROPERTIES:
:CUSTOM_ID: Package-Management-Repositoriesab0lel6184j0
:END:
By default, only GNU’s repositories are available to the package
managers of Emacs. I also want to use Melpa and org-mode’s repository,
so let’s add them! Note that the stock /elpa/ repository is renamed to
/gnu/ due to the addition of another Elpa repository, /nongnu/, which will
hosts packages that do not conform to the FSF’s copyright assignment.
Both the /gnu/ and the /nonfree/ repositories are Elpa repositories now,
and they are renamed here in order to avoid any confusion between the
two of them. Melpa is a community-maintained repository which contains
an absurd amount of Emacs packages.
#+begin_src emacs-lisp
(setq package-archives '(("melpa"  . "https://melpa.org/packages/")
                         ("gnu"    . "https://elpa.gnu.org/packages/")
                         ("nongnu" . "https://elpa.nongnu.org/nongnu/")))
#+end_src

** Straight
:PROPERTIES:
:CUSTOM_ID: Package-Management-Straightry3lel6184j0
:END:
For my package management, I prefer to use ~straight~ ([[https://github.com/raxod502/straight.el][Github]]). This is
due to its capacity of integrating nicely with ~use-package~, which also
supports ~general~ which I use for my keybindings (see below), but also
because with it I can specify where to retrieve packages that are not
on MELPA or ELPA but on Github and other online Git repositories too.
First, let’s bootstrap straight.
#+begin_src emacs-lisp
(defvar bootstrap-version)
(defvar comp-deferred-compilation-deny-list ()) ; workaround, otherwise straight shits itself
(let ((bootstrap-file
       (expand-file-name "straight/repos/straight.el/bootstrap.el" user-emacs-directory))
      (bootstrap-version 5))
  (unless (file-exists-p bootstrap-file)
    (with-current-buffer
        (url-retrieve-synchronously
         "https://raw.githubusercontent.com/raxod502/straight.el/develop/install.el"
         'silent 'inhibit-cookies)
      (goto-char (point-max))
      (eval-print-last-sexp)))
  (load bootstrap-file nil 'nomessage))
#+end_src

Now, we can refresh our package list in order to be able to install
stuff.
#+begin_src emacs-lisp
(package-initialize)
(unless package-archive-contents
  (package-refresh-contents))

#+end_src

From time to time, I fork some packages either because I’m trying to
implement something new in said package, or because the package is
unmaintained and I want to continue developing it a bit more. Straight
provides a nice feature for using forks of a package with its ~:fork~
option. If set to ~t~, then straight will attempt to retrieve the
package with the same name but with a different username on the same
host. This username is retrieved through the following variable:
#+begin_src emacs-lisp
(setq straight-host-usernames
      '((github . "Phundrak")
        (gitlab . "Phundrak")))
#+end_src

The huge advantage of straight is it clones through git the packages
it installs. This means development can be done directly on the
downloaded package. However, Forge (a Magit extension for interacting
with websites such as Github, Gitlab, and such) interacts by default
with the forge described by the ~origin~ remote, which isn’t necessarily
the one I want Forge to interact with by default. Therefore, all
default remotes are named ~straight~ so it won’t collide with my regular
development flow.
#+begin_src emacs-lisp
(setq straight-vc-git-default-remote-name "straight")
#+end_src

We finally come to the ~use-package~ installation. This is done like so:
#+begin_src emacs-lisp
(straight-use-package '(use-package :build t))
(setq use-package-always-ensure t)
#+end_src

** Which-key
:PROPERTIES:
:CUSTOM_ID: Keybinding-Management-Which-keymsblel6184j0
:END:
Which key is, I think, one of my favorite quality of life package.
When you begin a keybind, Emacs will show you all keybinds you can
follow the first one with in order to form a full keychord. Very
useful when you have a lot of keybinds and don’t remember exactly what
is what.
#+begin_src emacs-lisp
(use-package which-key
  :straight (:build t)

#+end_src

** General
:PROPERTIES:
:CUSTOM_ID: Keybinding-Management-Generalycflel6184j0
:END:
General is an awesome package for managing keybindings. Not only is it
oriented towards keychords by default (which I love), but it also
provides some integration with evil so that we can declare keybindings
for certain states only! This is a perfect replacement for ~define-key~,
~evil-define-key~, and any other function for defining keychords. And it
is also possible to declare a prefix for my keybindings! By default,
all keybinds will be prefixed with ~SPC~ and keybinds related to a
specific mode (often major modes) will be prefixed by a comma ~,~ (and
by ~C-SPC~ and ~M-m~ respectively when in ~insert-mode~ or ~emacs-mode~). You
can still feel some influence from my Spacemacs years here.
#+begin_src emacs-lisp

** Evil
:PROPERTIES:
:CUSTOM_ID: Keybinding-Management-Eviljg30fl6184j0

Evil emulates most of vim’s keybinds, because let’s be honest here,
they are much more comfortable than Emacs’.
#+begin_src emacs-lisp

  :straight (:build t)

  :init
  (setq evil-want-integration t

  (evil-set-initial-state 'messages-buffer-mode 'normal)
  (evil-set-initial-state 'dashboard-mode 'normal))
#+end_src

I want to undefine some of the default keybinds of Evil because it
does not match my workflow. Namely, I use the space key and the comma
as leaders for my keybinds, and I’m way too used to Emacs’ ~C-t~, ~C-a~,
~C-e~, and ~C-y~.
#+name: evil-undefine-keys
#+begin_src emacs-lisp :tangle no
(evil-global-set-key 'motion "t" 'evil-next-visual-line)

 "C-e" nil)
#+end_src

Something else that really bugs me is I use the bépo layout, which is
not at all like the qwerty layout. For instance, ~hjkl~ becomes ~ctsr~.
Thus, I need some bépo-specific changes.
#+name: evil-bepo
#+begin_src emacs-lisp :tangle no
(dolist (key '("c" "C" "t" "T" "s" "S" "r" "R" "h" "H" "j" "J" "k" "K" "l" "L"))
  (general-define-key :states 'normal key nil))

(general-define-key

#+end_src

This package enables and integrates Evil into a lot of different
modes, such as org-mode, dired, mu4e, etc. Again, I need some
additional code compared to most people due to the bépo layout.
#+begin_src emacs-lisp

  (add-hook 'evil-collection-setup-hook #'my/bépo-rotate-evil-collection)
  (evil-collection-init))
#+end_src

~undo-tree~ is my preferred way of undoing and redoing stuff. The main
reason is it doesn’t create a linear undo/redo history, but rather a
complete tree you can navigate to see your complete editing history.
One of the two obvious things to do are to tell Emacs to save all its
undo history fies in a dedicated directory, otherwise we’d risk
littering all of our directories. The second thing is to simply
globally enable its mode.
#+begin_src emacs-lisp
(use-package undo-tree
  :defer t
  :straight (:build t)
  :custom
  (undo-tree-history-directory-alist
   `(("." . ,(expand-file-name (file-name-as-directory "undo-tree-hist")
                               user-emacs-directory))))
  :init
  (global-undo-tree-mode)
  :config
  <<undo-tree-ignore-text-properties>>
  <<undo-tree-compress-files>>
  (setq undo-tree-visualizer-diff       t
        undo-tree-auto-save-history     t
        undo-tree-enable-undo-in-region t

        undo-strong-limit (* 12 1024 1024)

#+end_src

An interesting behavior from DoomEmacs is to compress the history
files with ~zstd~ when it is present on the system. Not only do we enjoy
much smaller files (according to DoomEmacs, we get something like 80%
file savings), Emacs can load them much faster than the regular files.
Sure, it uses more CPU time uncompressing these files, but it’s
insignificant and it’s still faster than loading a heavier file.
#+name: undo-tree-compress-files
#+begin_src emacs-lisp :tangle no
(when (executable-find "zstd")
  (defun my/undo-tree-append-zst-to-filename (filename)
    "Append .zst to the FILENAME in order to compress it."
    (concat filename ".zst"))
  (advice-add 'undo-tree-make-history-save-file-name

*** Ivy
:PROPERTIES:
:CUSTOM_ID: Packages-Configuration-Autocompletion-Ivy84q1fl6184j0
:END:
My main menu package is ~ivy~ which I use as much as possible –I’ve
noticed ~helm~ can be slow, very slow in comparison to ~ivy~ so I’ll use
the latter as much as possible. Actually, only ~ivy~ is installed for
now. I could have used ~ido~ too, but I find it to be a bit too
restricted in terms of features compared to ~ivy~.
#+begin_src emacs-lisp
(use-package ivy
  :straight (:build t)
  :defer t
  :diminish
  :bind (("C-s" . swiper)
         :map ivy-minibuffer-map

        ivy-use-selectable-prompt       t))
#+end_src

There is also [[https://github.com/raxod502/prescient.el][~prescient.el~]] that offers some nice features when
coupled with ~ivy~, guess what was born out of it? ~ivy-prescient~, of
course!
#+begin_src emacs-lisp
(use-package ivy-prescient
  :after ivy
  :straight (:build t))
#+end_src

I warned you I’d use too much ~all-the-icons~, I did!
#+begin_src emacs-lisp
(use-package all-the-icons-ivy
  :straight (:build t)
  :after (ivy all-the-icons)
  :hook (after-init . all-the-icons-ivy-setup))
#+end_src

A buffer popping at the bottom of the screen is nice and all, but have
you considered a floating buffer in the center of your frame?
#+begin_src emacs-lisp
(use-package ivy-posframe
  :defer t
  :after (:any ivy helpful)
  :hook (ivy-mode . ivy-posframe-mode)
  :straight (:build t)
  :init
  (ivy-posframe-mode 1)
  :config
  (setq ivy-fixed-height-minibuffer nil
        ivy-posframe-border-width   10
        ivy-posframe-parameters
        `((min-width  . 90)
          (min-height . ,ivy-height))))
#+end_src

Finally, let’s make ~ivy~ richer:
#+begin_src emacs-lisp
(use-package ivy-rich
  :straight (:build t)
  :after ivy
  :init
  (ivy-rich-mode 1))
#+end_src

*** Counsel
:PROPERTIES:
:CUSTOM_ID: Packages-Configuration-Autocompletion-Counselorr1fl6184j0
:END:
I could almost merge this chapter with the previous one since counsel
is a package that provides loads of completion functions for ivy. The
ones I find most useful are ~counsel-M-x~ and ~counsel-find-file~.
#+begin_src emacs-lisp
(use-package counsel
  :straight (:build t)
  :after recentf
  :defer t
  :after ivy
  :bind (("M-x"     . counsel-M-x)
         ("C-x b"   . counsel-ibuffer)
         ("C-x C-f" . counsel-find-file)
         :map minibuffer-local-map
         ("C-r" . 'counsel-minibuffer-history)))
#+end_src

*** Yasnippet
:PROPERTIES:
:CUSTOM_ID: Packages-Configuration-Autocompletion-Yasnippet68t1fl6184j0
:END:
Yasnippet allows you to insert some pre-made code by just typing a few
characters. It can even generate some string with Elisp expressions
and ask the user for some input in some precise places.
#+begin_src emacs-lisp
(use-package yasnippet
  :defer t
  :straight (:build t)
  :init
  (yas-global-mode)
  :hook ((prog-mode . yas-minor-mode)
         (text-mode . yas-minor-mode)))
#+end_src

Of course, yasnippet wouldn’t be as awesome as it is without premade
snippets.
#+begin_src emacs-lisp
(use-package yasnippet-snippets
  :defer t
  :after yasnippet
  :straight (:build t))
#+end_src

Similarly, yatemplate offers premade files rather than just strings.
That’s still yasnippet by the way.
#+begin_src emacs-lisp
(use-package yatemplate
  :defer t
  :after yasnippet
  :straight (:build t))
#+end_src

And finally, with ivy you can chose your snippets from a menu if
you’re not sure or if you don’t remember what your snippet is.
#+begin_src emacs-lisp
(use-package ivy-yasnippet
  :defer t
  :after (ivy yasnippet)
  :straight (:build t)
  :general
  (phundrak/leader-key
    :infix "i"
    :packages 'ivy-yasnippet
    "y" #'ivy-yasnippet))
#+end_src

** Applications

*** Bitwarden
:PROPERTIES:
:CUSTOM_ID: Packages-Configuration-Applications-Bitwarden-cjme4wv0rdj0
:END:
This package is still a very much work in progress one I’m developing
in order to interact with Bitwarden in Emacs with the help of the
[[https://github.com/bitwarden/cli][Bitwarden CLI]]. Use at your own risks.
#+begin_src emacs-lisp
(use-package bitwarden
  :defer t
  :straight (bitwarden :build t
                       :type git
                       :host nil
                       :repo "https://labs.phundrak.com/phundrak/bitwarden.el"))
#+end_src

*** Docker
:PROPERTIES:
:CUSTOM_ID: Packages-Configuration-Applications-Docker5ul0fl6184j0
:END:
Docker is an awesome tool for reproducible development environments.
Due to this, I absolutely need a mode for editing Dockerfiles.
#+begin_src emacs-lisp
(use-package dockerfile-mode
  :defer t
  :straight (:build t)
  :hook (dockerfile-mode . lsp-deferred)
  :init
  (put 'docker-image-name 'safe-local-variable #'stringp)
  :mode "Dockerfile\\'")
#+end_src

The ~docker~ package also provides interactivity with Docker and
docker-compose from Emacs.
#+begin_src emacs-lisp
(use-package docker
  :defer t
  :straight (:build t))
#+end_src

*** Elfeed
:PROPERTIES:
:CUSTOM_ID: Packages-Configuration-Applications-Elfeedoip0fl6184j0
:END:
Elfeed is a nice Atom and RSS reader for Emacs. The only thing I want
to change for now is the default search filter: I want to see not only
unread news but read news as well, a bit like my emails; and where the
database is to be stored.
#+begin_src emacs-lisp
(use-package elfeed
  :defer t
  :straight (:build t)
  :config
  <<elfeed-open-youtube-with-mpv>>
  :custom
  ((elfeed-search-filter "@6-months-ago")
   (elfeed-db-directory  (expand-file-name ".elfeed-db"
                                           user-emacs-directory))))
#+end_src

I don’t want YouTube videos to be open with my web browser when I
invoke ~elfeed-show-visit~, so I’ll advise this function so I can modify
the behavior of said function. Oh, and I already made [[#Packages-Configuration-Misc-Ytplay-wxm9weq0r4j0][a neat package]]
for playing YouTube videos and friends through [[https://ytdl-org.github.io/youtube-dl/][youtube-dl]] or its
superior fork [[https://github.com/yt-dlp/yt-dlp][yt-dlp]] in mpv.
#+name: elfeed-open-youtube-with-mpv
#+begin_src emacs-lisp
(defun my/elfeed-filter-youtube-videos (orig-fun &rest args)
  "Open with mpv the video leading to PATH"
  (let ((link (elfeed-entry-link elfeed-show-entry)))
    (when link
      (if (string-match-p ".*youtube\.com.*watch.*" link)
          ;; This is a YouTube video, open it with mpv
          (progn
            (require 'ytplay)
            (ytplay link))
        (apply orig-fun args)))))

(advice-add 'elfeed-show-visit :around #'my/elfeed-filter-youtube-videos)
#+end_src

A future improvement to be made is to let the user chose the
resolution of the video before it is launched. I may not always have
the best internet connection, and viewing 4K videos on a 1080p display
is not something very useful.

Elfeed-goodies is a package which enhances the Elfeed experience.
Aside from running its setup command as soon as possible, I also set
in this code block all my keybinds for Elfeed here.
#+begin_src emacs-lisp
(use-package elfeed-goodies
  :defer t
  :after elfeed
  :commands elfeed-goodies/setup
  :straight (:build t)
  :init
  (elfeed-goodies/setup)

    :keymaps 'elfeed-search-mode-map
    :packages 'elfeed
    <<general-keybindings-gen(table=elfeed-keybinds-search-mode-prefixed)>>))
#+end_src

Last but not least, my Elfeed configuration is stored in an org file
thanks to ~elfeed-org~.
#+begin_src emacs-lisp
(use-package elfeed-org
  :defer t
  :after elfeed
  :straight (:build t)
  :init

  :config
  (setq rmh-elfeed-org-files '("~/org/elfeed.org")))

**** Keybinds
:PROPERTIES:

:END:
First, here are the keybinds for Elfeed’s ~elfeed-show-mode~. They
aren’t prefixed by ~SPC~ like most of my keybinds, a direct keypress
will directly launch the function.
#+name: elfeed-keybinds-show-mode

Mu4e is a very eye-pleasing email client for Emacs, built around ~mu~
and which works well with ~mbsync~ (found in Arch’s ~isync~ package). For
me, the main advantage of mu4e is it has a modern interface for
emailing, and quite straightforward. I tried a couple of other email
clients for Emacs, and I even was for some time a Gnus user, but in
the end, mu4e really works best for me. Below you’ll find my

Quick sidenote: on ArchLinux, you’ll need to install either ~mu~ or
~mu-git~ from the AUR in order to use mu4e. I also have a ~.desktop~ file
so I can open mu4e directly from my program picker. It uses the shell
script ~emacsmail~ I’ve written [[file:bin.org::#Emacsmail-afffb7cd][here]].

***** Basic configuration
:PROPERTIES:
:CUSTOM_ID: Packages-Configuration-Applications-Email-Mu4e-Basic-configurationfxy0fl6184j0
:END:
First, let’s inform Emacs how it can send emails, using which service
and how. In my case, I use my own mail server.
#+name: mu4e-mail-service
#+begin_src emacs-lisp :tangle no
(setq smtpmail-smtp-server       "mail.phundrak.com"

      smtpmail-stream-type       'starttls
      message-send-mail-function 'smtpmail-send-it)
#+end_src

We also need to inform it on where my emails are stored on my machine,
and how to retrieve them.
#+name: mu4e-mail-on-machine
#+begin_src emacs-lisp :tangle no
(setq mu4e-get-mail-command "mbsync -a"

      mu4e-sent-folder      "/Sent"
      mu4e-drafts-folder    "/Drafts")
#+end_src

In the same vein of [[*Basic configuration][this bit of configuration]], I do not want mu4e to
insert my mail signature, ~org-msg~ already does that.

***** Bookmarks
:PROPERTIES:
:CUSTOM_ID: Packages-Configuration-Applications-Email-Mu4e-Bookmarkszo11fl6184j0
:END:
In mu4e, the main focus isn’t really mail directories such as your
inbox, your sent messages and such, but instead you manipulate
bookmarks which will show you emails depending on tags. This mean you
can create some pretty customized bookmarks that go way beyound your
simple inbox, outbox and all. Actually, four of my bookmarks have a
couple of filtering:
- anything in my inbox linked to my university
- the [[https://emacs-doctor.com/lists/listinfo][emacs-doctor mailing list]] (French Emacs mailing list)
- the conlang mailing lists
- and my inbox for any mail not caught by any of these filters
And all of them will have the requirement not to display any trashed
email. Actually, all of my bookmarks will have this requirement,
except for the bookmark dedicated to them as well as my sent emails.
I’ll add these latter requirements later.

Here are the requirements for my university bookmark. The regex
matches any email address which contains either ~up8.edu~ or
~univ-paris8~, which can be found in email addresses from the University
Paris 8 (my university).

#+name: mu4e-bookmarks-from-copy-to-gen
#+begin_src emacs-lisp :tangle no :exports none :var regex="test"
(mapconcat (lambda (x) (concat x ":" regex))

#+end_src

               (mapconcat (lambda (flag)
                            (concat flag ":" address))
                          '("list" "t" "f" "contact")
                          " OR ")))
           lists
           " OR ")
#+end_src

Next I need an inbox dedicated to the association I’m part of.
#+name: mu4e-bookmarks-filter-asso
#+header: :tangle no :cache yes
#+begin_src emacs-lisp
(let ((regex "/.*supran\\.fr/"))

: f:/.*supran\.fr/ OR c:/.*supran\.fr/ OR t:/.*supran\.fr/

As for the Emacs-doctor list, I need to match both the current, modern
mailing list address but also its old address. The same applies for
the emacs-devel mailing list as well as Github emails related to my
package ~eshell-info-banner.el~ ([[#Packages-Configuration-Emacs-built-ins-Eshell-Visual-configuratione7c2fl6184j0][see here]]). Here are the addresses to
match:

#+name: mu4e-emacs-mailing-lists
- ~/ateliers.*emacs.*/~
- ~/emacs-.*@gnu.org/~
- ~/.*eshell-info-banner.*/~
- ~/.*emacsfr.*/~

Another bookmark I wish to have is one dedicated to emails related to
more general development topics, including issues and PRs from Github.
#+name: mu4e-github-mailing-lists

When it comes to the conlang mailing list, let’s not match anything
from or to them. I’ll also include the auxlang mailing list –I’m not
subscribed anymore, but it’ll keep my inbox clean.
#+name: mu4e-conlanging-mailing-lists

As I said earlier, something that will often come back in my bookmarks
is the emails must not be trashed to appear. I want also to display
junk emails, so I end up with the following rule:
#+name: mu4e-bookmarks-default-filter
#+header: :tangle no :cache yes
#+begin_src emacs-lisp
(mapconcat #'identity
           `("NOT flag:trashed"

                                        '("/Inbox" "/Junk")
                                        " OR ")))

#+end_src

And for the last string-generating code, let’s describe my main inbox:

Sometimes, bookmarks are a bit too restrictive when I want to search
for stuff. Simply jumping to a mail directory, or maildir, is more
than enough. In mu4e, with my current setup, I can jump to any maildir
with the shortcut ~Jo~ in normal-mode, and I just need to chose in a
list the maildir I want to jump to. But it can be faster.

With this piece of code, I can simply jump to my inbox maildir with
~Ji~, to my sent messages with ~Js~, and so on.

I’m not a huge fan of mu4e’s default icons marking my emails, so I’ll
redefine them as follows. Be aware the name of these icons are from
/faicon/ in the package ~all-the-icons~.

By default, Evil has some pretty annoying keybindings for users of the
bépo layout: ~hjkl~ becomes ~ctsr~ for us. Let’s undefine some of these:
#+name: mu4e-keybindings-undef
#+begin_src emacs-lisp :tangle no
(phundrak/undefine
  :keymaps 'mu4e-view-mode-map

(phundrak/undefine
  :keymaps '(mu4e-view-mode-map mu4e-headers-mode-map)
  :packages 'mu4e

#+end_src

Now, let’s define some keybindings for mu4e’s view mode, that is when
we are viewing an email. All these keybindings will reside between the
major-mode specific leader key ~,~ and most of these keybindings can be
described with a simple function:

Two other keybinds are added without a prefix, just for the sake of
convenience.

I’ll also declare two keybinds for mu4e’s headers mode.

#+end_src

I will also redefine without a leader key ~ctsr~ in order to be able to
move freely (remember, bépo layout for me).

Finally, let’s declare a couple of keybindings for when we are
composing a message. This time, all my keybindings are prefixed with
the major-mode leader and call a simple function.

EMMS has two default ways of finding files: either a built-in function
relatively slow but portable, or with ~find~ which is arguably faster
but less portable. Honestly, I don’t care about portability, I’ll
always use this Emacs config on Linux, but I don’t want to use ~find~
either since there is something even faster: ~fd~.

First we’ll declare a variable that can hold the path to the ~fd~
executable:
#+name: emms-fd-name
#+begin_src emacs-lisp
(defvar emms-source-file-fd (executable-find "fd"))
#+end_src

Then, we need to declare a new function that will use ~fd~ to find
files. The function, as specified by the documentation of
~emms-source-file-directory-tree-function~, receives two arguments ~dir~
and ~regex~. We can work with that!
#+name: emms-fd-function
#+begin_src emacs-lisp
(defun emms-source-file-directory-tree-fd (dir regex)
  "Return a list of all files under DIR that match REGEX.
This function uses the external fd utility. The name for fd may
be supplied using `emms-source-file-fd'."
  (with-temp-buffer
    (call-process emms-source-file-fd
                  nil t nil
                  "-L" ; follow symlinks
                  regex
                  "-t f"
                  (expand-file-name dir))
    (delete ""
            (split-string (buffer-substring (point-min)
                                          (point-max))
                          "\n"))))
#+end_src

We can finally set this function as our search function.
#+name: emms-search-set-variable
#+begin_src emacs-lisp
(setq emms-source-file-directory-tree-function #'emms-source-file-directory-tree-fd)

obfuscate which Git commands are used to make things happen. Such a

[[https://github.com/alphapapa][Alphapapa]] also created an awesome package for Magit: magit-todos which
display in the Magit buffer a list of TODOs found in the current
project to remind you of what to do next.

First, let’s setup our todo keywords with ~hl-todo~. A good few todo
keywords are already defined in the ~hl-todo-keyword-faces~ variable.
Why not use them? ~hl-todo-mode~ enables fontlock highlight of these
keywords in a buffer. Let’s enable this mode globally.

We can now configure properly ~magit-todos~.

*** Parinfer
:PROPERTIES:
:CUSTOM_ID: Packages-Configuration-Editing-Parinfermxy1fl6184j0
:END:
Don’t let the name of the package fool you! ~parinfer-rust-mode~ is not
a ~parinfer~ mode for ~rust-mode~, but a mode for ~parinfer-rust~. ~parinfer~
was a project for handling parenthesis and other double markers in a
much more intuitive way when writing Lisp code. However, it is now out
of date (last commit was on January 2nd, 2019) and the repository has
since been archived. New implementations then appeared, one of them is
[[https://github.com/eraserhd/parinfer-rust][~parinfer-rust~]], obviously written in Rust, around which
~parinfer-rust-mode~ is built. Enabling ~parinfer-rust-mode~ should also
automatically disable ~smartparens-mode~ in order to avoid conflicting
behavior.

*** Smartparens
:PROPERTIES:
:CUSTOM_ID: Packages-Configuration-Editing-Smartparens-zve93mk0k4j0
:END:
~smartparens~ is a package similar to ~parinfer~, but while the latter is
more specialized for Lisp dialects, ~smartparens~ works better with
other programming languages that still uses parenthesis, but not as
much as Lisp dialects; think for example C, C++, Rust, Javascript, and
so on.

~string-edit~ is a cool package that allows the user to write naturally
a string and get it automatically escaped for you. No more manually

*** Writeroom
:PROPERTIES:

On the other hand, ~writeroom~ allows the user to enter a

*** Dired
:PROPERTIES:
:CUSTOM_ID: Packages-Configuration-Emacs-built-ins-Diredao42fl6184j0
:END:
Dired is Emacs’ built-in file manager. It’s really great, and replaces
any graphical file manager for me most of the time because:
- I am not limited to /x/ tabs or panes
- All actions can be done with keybindings
- I get a consistent behavior between Dired and Emacs, since it’s the
  same thing.
However, the only thing I lack still is thumbnails. In any case, I
need still to make some tweaks in order to make it usable for
me.

#+end_src

Dired-x stands for “dired extra” which provides a couple more features
that are for some reason not included in dired yet.
#+begin_src emacs-lisp
(use-package dired-x

#+end_src

Copying files with Dired is a blocking process. It’s usually fine when
there’s not a lot to copy, but it becomes more annoying when moving
larger files. The package ~dired-rsync~ allows to copy files with ~rsync~
in the background so we can carry on with our tasks while the copy is
happening.
#+begin_src emacs-lisp
(use-package dired-rsync
  :if (executable-find "rsync")
  :defer t
  :straight (:build t)

    :packages 'dired-rsync
    "C-r" #'dired-rsync))
#+end_src

~dired-du~ provides the user with the option to be able to see the size
of directories as they are, rather than just the size of their
inode. However, I will not enable it by default as it can take some
time to get the actual size of a directory.
#+begin_src emacs-lisp
(use-package dired-du

  :straight (:build t)

   :packages 'dired-du
   "»" #'dired-du-mode))
#+end_src

This package on the other hand provides Git information to the user in
the current dired buffer in a similar way to how Github and Gitea
display the latest commit message and its age about a file in the file
tree. And by default, I want ~dired-git-info~ to hide file details.
#+begin_src emacs-lisp
(use-package dired-git-info
  :after (dired)
  :straight (:build t)

Diredfl makes dired colorful, and much more readable in my opinion.
#+begin_src emacs-lisp
(use-package diredfl
  :after (dired all-the-icons)
  :straight (:build t)
  :init
  (diredfl-global-mode 1))
#+end_src

Dired can benefit from ~fd~, a fast reimplementation of ~find~, to
increase the speed of ~find-dired~.
#+begin_src emacs-lisp

  :defer t
  :straight (:build t)
  :init

And let’s add some fancy icons in dired!
#+begin_src emacs-lisp

              :around
              #'my/all-the-icons-dired--refresh))

Lastly, let’s install some extensions to ~image-dired~.

*** Compilation mode
:PROPERTIES:

:END:
After reading about a blog article, I found out it is possible to run
quite a few things through ~compilation-mode~, so why not? First, let’s
redefine some keybinds for this mode. I’ll also define a general
keybind in order to re-run my programs from other buffers than the
~compilation-mode~ buffer. I also want to follow the output of the
compilation buffer, as well as enable some syntax highlighting.
#+begin_src emacs-lisp

Eshell is a built-in shell available from Emacs which I use almost as
often as fish. Some adjustments are necessary to make it fit my taste
though.

**** Aliases
:PROPERTIES:
:CUSTOM_ID: Packages-Configuration-Emacs-built-ins-Eshell-Aliasesom72fl6184j0
:END:
First, let’s declare our list of “dumb” aliases we’ll use in
Eshell. You can find them here.
#+name: eshell-alias-file
#+begin_src emacs-lisp :tangle no
(setq eshell-aliases-file (expand-file-name "eshell-aliases" user-emacs-directory))
#+end_src

A couple of other aliases will be defined through custom Elisp
functions, but first I’ll need a function for concatenating a shell
command into a single string:
#+name: eshell-concat-shell-command
#+begin_src emacs-lisp :tangle no
(defun phundrak/concatenate-shell-command (&rest command)
  "Concatenate an eshell COMMAND into a single string.
All elements of COMMAND will be joined in a single
space-separated string."
  (mapconcat #'identity command " "))
#+end_src

I’ll also declare some aliases here, such as ~open~ and ~openo~ that
respectively allow me to open a file in Emacs, and same but in another
window.
#+name: eshell-alias-open
#+begin_src emacs-lisp :tangle no
(defalias 'open #'find-file)
(defalias 'openo #'find-file-other-window)
#+end_src

The default behavior of ~eshell/clear~ is not great at all, although it
clears the screen it also scrolls all the way down. Therefore, let’s
alias it to ~eshell/clear-scrollback~ which has the correct behavior.
#+name: eshell-alias-clear
#+begin_src emacs-lisp :tangle no
(defalias 'eshell/clear #'eshell/clear-scrollback)
#+end_src

As you see, these were not declared in my dedicated aliases file but
rather were declared programmatically. This is because I like to keep
my aliases file for stuff that could work too with other shells were
the syntax a bit different, and aliases related to Elisp are kept
programmatically. I’ll also declare ~list-buffers~ an alias of ~ibuffer~
because naming it that way kind of makes more sense to me.
#+name: eshell-alias-buffers
#+begin_src emacs-lisp :tangle no
(defalias 'list-buffers 'ibuffer)
#+end_src

I still have some stupid muscle memory telling me to open ~emacs~, ~vim~
or ~nano~ in Eshell, which is stupid: I’m already inside Emacs and I
have all its power available instantly. So, let’s open each file
passed to these commands.
#+name: eshell-alias-emacs
#+begin_src emacs-lisp :tangle no
(defun eshell/emacs (&rest file)
  "Open each FILE and kill eshell.
Old habits die hard."
  (when file
    (dolist (f (reverse file))
      (find-file f t))))
#+end_src

Finally, I’ll declare ~mkcd~ which allows the simultaneous creation of a
directory and moving into this newly created directory. And of course,
it will also work if the directory also exists or if parent
directories don’t, similarly to the ~-p~ option passed to ~mkdir~.
#+name: eshell-alias-mkcd
#+begin_src emacs-lisp :tangle no
(defun eshell/mkcd (dir)
  "Create the directory DIR and move there.
If the directory DIR doesn’t exist, create it and its parents
if needed, then move there."
  (mkdir dir t)
  (cd dir))
#+end_src

**** Autosuggestion
:PROPERTIES:
:CUSTOM_ID: Packages-Configuration-Emacs-built-ins-Eshell-Autosuggestion-kf6ipm1195j0
:END:
I really like fish’s autosuggestion feature, so let’s reproduce it
here!
#+begin_src emacs-lisp
(use-package esh-autosuggest
  :defer t
  :after eshell
  :straight (:build t)
  :hook (eshell-mode . esh-autosuggest-mode)

#+end_src

**** Commands
:PROPERTIES:
:CUSTOM_ID: Packages-Configuration-Emacs-built-ins-Eshell-Commands-n8w3fh2195j0
:END:
When I’m in Eshell, sometimes I wish to open multiple files at once in
Emacs. For this, when I have several arguments for ~find-file~, I want
to be able to open them all at once. Let’s modify ~find-file~ like so:
#+BEGIN_SRC emacs-lisp
(defadvice find-file (around find-files activate)
  "Also find all files within a list of files. This even works recursively."
  (if (listp filename)
      (cl-loop for f in filename do (find-file f wildcards))
    ad-do-it))
#+END_SRC

I also want to be able to have multiple instances of Eshell opened at
once. For that, I declared the function ~eshell-new~ that does exactly
that.
#+begin_src emacs-lisp
(defun eshell-new ()
  "Open a new instance of eshell."
  (interactive)
  (eshell 'N))
#+end_src

A very useful command I use often in fish is ~z~, a port from bash’s and
zsh’s command that allows to jump around directories based on how
often we go in various directories.
#+begin_src emacs-lisp
(use-package eshell-z
  :defer t
  :after eshell
  :straight (:build t)
  :hook (eshell-mode . (lambda () (require 'eshell-z))))
#+end_src

**** Environment Variables
:PROPERTIES:
:CUSTOM_ID: Packages-Configuration-Emacs-built-ins-Eshell-Environment-Variablesmna2fl6184j0
:END:
Some environment variables need to be correctly set so Eshell can
correctly work. I would like to set two environment variables related
to Dart development: the ~DART_SDK~ and ~ANDROID_HOME~ variables.
#+BEGIN_SRC emacs-lisp
(setenv "DART_SDK" "/opt/dart-sdk/bin")
(setenv "ANDROID_HOME" (concat (getenv "HOME") "/Android/Sdk/"))
#+END_SRC

The ~EDITOR~ variable also needs to be set for git commands, especially the
~yadm~ commands.
#+BEGIN_SRC emacs-lisp
(setenv "EDITOR" "emacsclient -c -a emacs")
#+END_SRC

Finally, for some specific situations I need ~SHELL~ to be set to
something more standard than fish:
#+begin_src emacs-lisp
(setenv "SHELL" "/bin/sh")
#+end_src

**** Visual configuration

I like to have at quick glance some information about my machine when
I fire up a terminal. I haven’t found anything that does that the way
I like it, so [[https://github.com/Phundrak/eshell-info-banner.el][I’ve written a package]]! It’s actually available on
MELPA, but since I’m the main dev of this package, I’ll keep track of
the git repository.

  :config
  (setq eshell-info-banner-width 80
        eshell-info-banner-partition-prefixes '("/dev" "zroot" "tank")))

Another feature I like is fish-like syntax highlight, which brings
some more colors to Eshell.
#+begin_src emacs-lisp

Powerline prompts are nice, git-aware prompts are even better!
~eshell-git-prompt~ is nice, but I prefer to write my own package for
that.

*** Info

*** Tramp

Tramp is an Emacs built-in package that allows the user to connect to
various hosts using various protocols, such as ~ssh~ and
~rsync~. However, I have some use-case for Tramp which are not
supported natively. I will describe them here.
#+begin_src emacs-lisp

#+end_src

**** Yadm
:PROPERTIES:
:CUSTOM_ID: Packages-Configuration-Emacs-built-ins-Tramp-Yadma8f2fl6184j0
:END:
[[https://yadm.io/][~yadm~]] is a git wrapper made to easily manage your dotfiles. It has
loads of features I don’t use (the main one I like but don’t use is
its [[https://yadm.io/docs/templates][Jinja-like host and OS-aware syntax]]), but unfortunately Magit
doesn’t play nice with it. Tramp to the rescue, and this page explains
how! Let’s just insert in my config this code snippet:
#+name: tramp-add-yadm
#+begin_src emacs-lisp :tangle no
(add-to-list 'tramp-methods
                   '("yadm"
                     (tramp-login-program "yadm")
                     (tramp-login-args (("enter")))
                     (tramp-login-env (("SHELL") ("/bin/sh")))
                     (tramp-remote-shell "/bin/sh")
                     (tramp-remote-shell-args ("-c"))))

** EXWM
:PROPERTIES:
:CUSTOM_ID: Packages-Configuration-EXWM-pr14yxs09aj0
:END:
So, I’m finally slowly getting back to EXWM. I tried it a couple of
years ago, but that was with the SpacemacsOS layer on Spacemacs, on a
laptop which got accidentaly formatted before I could save my config
and all… So it got me some time to come back. I’m still a bit worried
about Emacs being single threaded, so if I get one blocking function
blocking Emacs, my whole desktop will hang, but for now I haven’t had
this issue.

All my EXWM config is enabled only if I launch Emacs with the argument
~--with-exwm~, otherwise none of the related packages get installed, let
alone activated and made available.

First, I need to install the /X protocol Emacs Lisp Bindings/. It
doesn’t seem to be available in any repo, so I’ll install it directly
from Git.
#+begin_src emacs-lisp
(use-package xelb
  :if (seq-contains-p command-line-args "--with-exwm")
  :straight (xelb :build t
                  :type git
                  :host github
                  :repo "emacs-straight/xelb"
                  :fork "ch11ng/xelb"))
#+end_src

Next is a function I’ve +stolen+ copied from Daviwil’s [[https://config.daviwil.com/desktop][desktop
configuration]]. This allows to launch software in the background
easily.
#+begin_src emacs-lisp
(defun exwm/run-in-background (command &optional once)
  (let ((command-parts (split-string command " +")))
    (apply #'call-process `(,(car command-parts) nil 0 nil ,@(cdr command-parts)))))
#+end_src

In order to launch Emacs with EXWM with ~startx~, I need a ~xinit~ file.
This one is exported to ~$HOME/.xinitrc.emacs~.
#+begin_src sh :tangle ~/.xinitrc.emacs
#!/bin/sh

xhost +SI:localuser:$USER

# Set fallback cursor
xsetroot -cursor_name left_ptr

# If Emacs is started in server mode, `emacsclient` is a convenient way to edit
# files in place (used by e.g. `git commit`)
export VISUAL=emacsclient
export EDITOR="$VISUAL"

# in case Java applications display /nothing/
# wmname LG3D
# export _JAVA_AWT_WM_NONREPARENTING=1

exec emacs --with-exwm
#+end_src

*** EXWM itself
:PROPERTIES:
:CUSTOM_ID: Packages-Configuration-EXWM-EXWM-itself-hhgexz61aaj0
:END:
Now we come to the plat de résistance. Like with ~xelb~, I’m using its
Git source to install it to make sure I get the right version --- the
version available on the GNU ELPA is from the same source, true, but I
don’t know at which rate it is updated. And more packages down the
line will depend on this Git repository, so I might as well just clone
it right now.

As you can see, in the ~:config~ secion I added to two hooks functions
so buffers are accurately renamed. While the average X window will
simply get the name of the current X window, I want Firefox and
Qutebrowser to be prefixed with the name of the browser. Actually, all
these will be renamed this way:
#+name: exwm-renamed-buffers-list
- Kitty
- Qutebrowser

#+name: exwm-gen-buffers-rename
#+header: :exports none :tangle no
#+begin_src emacs-lisp :var buffers=exwm-renamed-buffers-list :cache yes
(format "%s\n%S"
        (mapconcat (lambda (buffer)
                     (let ((buffer-name (car buffer)))
                       (format "(\"%s\" %S)"
                               (downcase buffer-name)
                               `(exwm-workspace-rename-buffer (concat ,buffer-name
                                                                      " - "
                                                                      exwm-title)))))
                   buffers
                   "\n")
        '(_otherwise (exwm-workspace-rename-buffer exwm-title)))

            (pcase exwm-class-name
              <<exwm-gen-buffers-rename()>>)))
#+end_src

As you can see below, in the ~:config~ section I added two advices and one
hook in order to correctly integrate evil with EXWM. When I’m in an X
window, I want to be in insert-mode so I can type however I want.
However, when I exit one, I want to default back to normal-mode.
#+name: exwm-advices-evil
#+begin_src emacs-lisp :tangle no
(add-hook 'exwm-manage-finish-hook (lambda () (call-interactively #'exwm-input-release-keyboard)))
(advice-add #'exwm-input-grab-keyboard :after (lambda (&optional id) (evil-normal-state)))
(advice-add #'exwm-input-release-keyboard :after (lambda (&optional id) (evil-insert-state)))
#+end_src

Secondly, I add ~i~, ~C-SPC~, and ~M-m~ as exwm prefix keys so they aren’t
sent directly to the X windows but caught by Emacs (and EXWM). I’ll
use the ~i~ key in normal-mode to enter ~insert-mode~ and have Emacs
release the keyboard so the X window can grab it. Initially, I had
~s-<escape>~ as a keybind for grabbing back the keyboard from an X
window, as if I were in insert mode and wanted to go back to normal
mode, and I had ~s-I~ to toggle keyboard grabbing. But I found myself
more than once trying to use ~s-<escape>~ to toggle this state, ~s-I~
completely forgotten. So I removed ~s-I~ and made ~s-<escape>~ behave like
~s-I~ once did.
#+name: exwm-prefix-keys
#+begin_src emacs-lisp :tangle no
(general-define-key
 :keymaps 'exwm-mode-map
 :states 'normal
 "i" #'exwm-input-release-keyboard)

(exwm-input-set-key (kbd "s-<escape>") #'exwm-input-toggle-keyboard)

(push ?\i exwm-input-prefix-keys)
(push (kbd "C-SPC") exwm-input-prefix-keys)
(push (kbd "M-m") exwm-input-prefix-keys)
#+end_src

As stated a couple of times in my different configuration files, I’m
using the bépo layout, which means the default keys in the number row
are laid as follow:
#+name: exwm-bepo-number-row
#+begin_src emacs-lisp :tangle no
(defconst exwm-workspace-keys '("\"" "«" "»" "(" ")" "@" "+" "-" "/" "*"))
#+end_src

With this, we can create keybinds for going or sending X windows to
workspaces 0 to 9.
#+name: exwm-workspace-keybinds
#+begin_src emacs-lisp :tangle no
(setq exwm-input-global-keys
      `(,@exwm-input-global-keys
        ,@(mapcar (lambda (i)
                    `(,(kbd (format "s-%s" (nth i exwm-workspace-keys))) .
                      (lambda ()
                        (interactive)
                        (exwm-workspace-switch-create ,i))))
                  (number-sequence 0 9))
        ,@(mapcar (lambda (i)
                    `(,(kbd (format "s-%d" i)) .
                      (lambda ()
                        (interactive)
                        (exwm-workspace-move-window ,(let ((index (1- i)))
                                                       (if (< index 0)
                                                           (- 10 index)
                                                         ;; FIXME: does not work with s-0
                                                         index))))))
                  (number-sequence 0 9))))
#+end_src

You can then see the list of the keybinds I have set for EXWM, which
are all prefixed with ~SPC x~ in normal mode (and ~C-SPC x~ in insert
mode), with the exception of ~s-RET~ which opens an eshell terminal.

Org is the main reason I am using Emacs. It is an extremely powerfu
tool when you want to write anything that is not necessarily primarily
programming-related, though it absolutely can be! Org can be a
replacement for anything similar to LibreOffice Writer, LibreOffice
Calc, and LibreOffice Impress. It is a much more powerful (and older)
version of Markdown which can be exported to LaTeX and HTML at least,
rendering writing web pages and technical, scientific documents much
simpler than writing manually HTML and LaTeX code, especially when a
single document source is meant to be exported for both formats. And
since org is an Emacs package, that also means it can be greatly
extended however we like!

The main feature from ~evil-org~ that I love is how easy it is to modify
some keybindings for keyboards layouts that do not have ~hjkl~, such as
the bépo layout (or Dvorak or Colemak if you are into that). But it
also adds a ton of default keybindings which are just much more
comfortable than the default ones you get with evil and org naked.

Since very recently, the ~contrib/lisp/~ directory of org moved out of
the main repository to [[https://git.sr.ht/~bzg/org-contrib][this repository]]. On the other hand,
~contrib/scripts/~ moved to [[https://code.orgmode.org/bzg/worg/src/master/code][the worg repository]], but I don’t need
it. The main reason I want ~org-contrib~ is due to ~ox-extra~ that allow
the usage of the ~:ignore:~ tag in org.

One of the amazing features of org-mode is its literary programming capacities
by running code blocks from within Org-mode itself. But for that, only a couple
of languages are supported directly by Org-mode itself, and they need to be
activated. Here are the languages I activated in my Org-mode configuration:

A package I use from time to time is ~ob-latex-as-png~ which allows me

A useful package I like is ~toc-org~ which creates automatically a table
of contents. My main usage for this however is not just to create a
table of content of my files to quickly jump around my file (I have
~counsel-org-goto~ for that), but it is for creating table of contents
for org files that will be hosted and viewable on Github.
#+begin_src emacs-lisp

~electric-mode~ also bothers me a lot when editing org files, so let’s deactivate it:

As explained in my [[https://blog.phundrak.com/better-custom-ids-orgmode/][blog post]], org-mode is terrible with coming up with

When ~org-capture~ is invoked, it will ask which template we wish to

the manner described by /insertion mode/.

**** Emphasize text
:PROPERTIES:
:CUSTOM_ID: Custom-Elisp-Org-Functions-Emphasize-textkilkel6184j0
:END:
Sometimes, I want to emphasize some text in my org-mode documents.
It’s very possible to just go to the begining of the chosen text, add
the marker, then go to the end of the text than needs emphasis and add
another marker, and I’m sure most people are fine with that. But I
also like being able to select a region and hit a keybind to emphasize
it that way. The table [[org-emphasis-character]] lists the emphasis
characters in org-mode, their role, and the character code of each
emphasis character. From that, creating functions that emphasize a
selected text is quite easy.

#+name: org-emphasis-character
| Emphasis       | Character | Character code |

*** Exporters
:PROPERTIES:
:CUSTOM_ID: Packages-Configuration-Org-mode-File-exportik95fl6184j0
:END:
I want to disable by default behavior of ~^~ and ~_~ for only one
character, making it compulsory to use instead ~^{}~ and ~_{}~
respectively. This is due to my frequent usage of the underscore in my
org files as a regular character and not a markup one, especially when
describing phonetics evolution. So, let’s disable it:
#+NAME: org-use-sub-superscripts
#+BEGIN_SRC emacs-lisp :tangle no

#+END_SRC

**** ConlangDict
:PROPERTIES:
:CUSTOM_ID: Packages-Configuration-Org-mode-Exporters-ConlangDict-wvi7vaa16fj0
:END:
I am currently working on two new exporters as well as custom links
for my org websites. The first one is the most generic one, it exports
my org files to ~.tsx~ files NextJS will use to render them.
#+begin_src emacs-lisp
(use-package ox-conlang-tsx
  :defer t
  :after '(org ox)
  :straight (ox-conlang-tsx :type git
                            :host nil
                            :repo "https://labs.phundrak.com/phundrak/ox-conlang-tsx"
                            :build t))
#+end_src

The second exporter is similar to ~ox-json~, but with some special
twists for my needs. Indeed, I need some elements of ~ox-conlang-json~
to be compatible with ~ox-conlang-tsx~.
#+begin_src emacs-lisp
;; (use-package ox-conlang-json
;;   :defer t
;;   :after '(org ox)

;;                              :build t))
#+end_src

Finally, I also need a handler for custom links begining in ~conlang~,
like ~[[conlang:English:dog]]~. ~ol-conlang~ handles that.
#+begin_src emacs-lisp
(use-package ol-conlang
  :defer t
  :after '(org ol)
  :straight (ol-conlang :type git
                        :host nil
                        :repo "https://labs.phundrak.com/phundrak/ol-conlang"
                        :build t))
#+end_src

**** Epub
:PROPERTIES:
:CUSTOM_ID: Packages-Configuration-Org-mode-File-export-Epub-w5ycfuz095j0

A backend for exporting files through org I like is ~ox-epub~ which, as
you can guess, exports org files to the [[https://www.w3.org/publishing/epub32/][Epub format]].

**** HTML
:PROPERTIES:
:CUSTOM_ID: Packages-Configuration-Org-mode-File-export-HTMLxjc5fl6184j0

On HTML exports, Org-mode tries to include a validation link for the
exported HTML. Let’s disable that since I never use it.
#+NAME: org-html-validation

This package allows for live-previewing the HTML export of an org
buffer in an XWidget Webkit browser window. But when testing it, it’s
not great for large org files, I should keep its usage for smaller org
files.
#+begin_src emacs-lisp
(use-package preview-org-html-mode

I manage [[https://blog.phundrak.com][my blog]] with [[https://gohugo.io/][Hugo]]. Although it natively supports the org

let’s directly export our org files as markdown files and let Hugo do
the rest of the job for us!
#+begin_src emacs-lisp

#+end_src

I also have a function for publishing my blog once I exported my
articles with ~ox-hugo~. It will compile blog into a ~public/~ directory
and copy its content over to my remote server.
#+begin_src emacs-lisp

**** LaTeX
:PROPERTIES:
:CUSTOM_ID: Packages-Configuration-Org-mode-File-export-LaTeXg2b5fl6184j0

When it comes to exports, I want the LaTeX and PDF exports to be done

variable:
#+NAME: org-latex-compiler
#+BEGIN_SRC emacs-lisp :tangle no
(setq org-latex-compiler "xelatex")
#+END_SRC

A new backend that was introduced in org-mode for LaTeX source block
coloring is ~engraved~, relying on ~engraved-faces~. Let’s install this
package.
#+begin_src emacs-lisp
(use-package engrave-faces
  :straight (:build t)
  :defer t
  :after ox)
#+end_src

We can now tell Emacs to use the ~engraved~ backend.
#+NAME: org-latex-listings
#+BEGIN_SRC emacs-lisp :tangle no

#+END_SRC

The default packages break my LaTeX exports: for some reasons, images
are not loaded and exported in PDFs, so I needed to redifine the
default packages excluding the one that broke my exports; namely, I
need to remove ~inputenc~, ~fontenc~ and ~grffile~. I also added some default
packages:
- ~minted~ for syntax highlighting
- ~cleveref~ for better references to various elements.
- ~svg~ for inserting SVG files in PDF outputs
- ~booktabs~ for nicer tables
- and ~tabularx~ for tabulars with adjustable columns
#+NAME: org-latex-default-packages

                   (""           "svg")
                   (""           "booktabs")
                   (""           "tabularx")))
  (add-to-list 'org-latex-default-packages-alist package t))

(setq org-latex-reference-command "\\cref{%s}")
#+END_SRC

By the way, reference links in LaTeX should be written in this format,
since we are using ~cleveref~:
#+NAME: org-export-latex-hyperref-format
#+BEGIN_SRC emacs-lisp :tangle no
(setq org-export-latex-hyperref-format "\\ref{%s}")
#+END_SRC

And Minted should be default break lines if a line is too long:
#+name: org-export-latex-minted-options
#+begin_src emacs-lisp :tangle no
(setq org-latex-minted-options '(("breaklines")
                                 ("tabsize" "2")
                                 ("frame" "single")
                                 ("autogobble")))
#+end_src

When it comes to the export itself, the latex file needs to be
processed several times through XeLaTeX in order to get some
references right. Don’t forget to also run bibtex!
#+NAME: org-latex-pdf-process
#+BEGIN_SRC emacs-lisp :tangle no
(setq org-latex-pdf-process
      '("xelatex -8bit -shell-escape -interaction nonstopmode -output-directory %o %f"
        "bibtex %b"
        "xelatex -8bit -shell-escape -interaction nonstopmode -output-directory %o %f"
        "xelatex -8bit -shell-escape -interaction nonstopmode -output-directory %o %f"))
#+END_SRC

Finally, org-mode is supposed to automatically clean logfiles after it
exports an org file to LaTeX. However, it misses a few, so I need to
add their extension like so:
#+name: org-latex-logfiles-add-extensions
#+begin_src emacs-lisp :tangle no
(dolist (ext '("bbl" "lot"))
  (add-to-list 'org-latex-logfiles-extensions ext t))
#+end_src

Yet another exporter I enjoy is [[https://github.com/dantecatalfamo/ox-ssh][~ox-ssh~]] with which I manage my

*** Keybindings
:PROPERTIES:
:CUSTOM_ID: Packages-Configuration-Org-mode-Keybindingsv0e5fl6184j0
:END:
Be prepared, I have a lot of keybindings for org-mode! They are all
prefixed with a comma ~,~ in normal mode.
#+name: org-keybinds-various
| Key chord | Function            | Description |

I then have a couple of babel-related functions.
#+name: org-keybinds-babel
| Key chord | Function                            | Description |
|-----------+-------------------------------------+-------------|

| bi        | org-babel-view-src-block-info       |             |

The ~org-babel-transient~ hydra allows me to quickly navigate between
code blocks and interact with them. This code block was inspired by
one you can find in Spacemacs.

We next have keybindings related to org-mode’s agenda capabilities. We
can schedule a todo header for some dates, or set a deadline.
#+name: org-keybinds-dates

| dT        | org-time-stamp-inactive |             |

Let’s now define some keybinds for inserting stuff in our org buffer:
#+name: org-keybinds-insert
| Key chord | Function                      | Description |
|-----------+-------------------------------+-------------|

| it        | org-set-tags-command          |             |

There isn’t a lot of stuff I can jump to yet, but there’s still some:
#+name: org-keybinds-jump
| Key chord | Function             | Description |
|-----------+----------------------+-------------|

*** LaTeX formats
:PROPERTIES:
:header-args:emacs-lisp: :tangle no :exports code :results silent
:CUSTOM_ID: Packages-Configuration-Org-mode-LaTeX-formatszjf5fl6184j0
:END:
I currently have two custom formats for my Org-mode exports: one for general use
(initialy for my conlanging files, hence its ~conlang~ name), and one for beamer
exports.

Below is the declaration of the ~conlang~ LaTeX class:
#+NAME: org-latex-class-conlang
#+BEGIN_SRC emacs-lisp
'("conlang"
  "\\documentclass{book}"
  ("\\chapter{%s}" . "\\chapter*{%s}")
  ("\\section{%s}" . "\\section*{%s}")
  ("\\subsection{%s}" . "\\subsection*{%s}")
  ("\\subsubsection{%s}" . "\\subsubsection*{%s}"))
#+END_SRC

And here is the declaration of the ~beamer~ class:
#+NAME: org-latex-class-beamer
#+BEGIN_SRC emacs-lisp
`("beamer"
  ,(concat "\\documentclass[presentation]{beamer}\n"
           "[DEFAULT-PACKAGES]"
           "[PACKAGES]"
           "[EXTRA]\n")
  ("\\section{%s}" . "\\section*{%s}")
  ("\\subsection{%s}" . "\\subsection*{%s}")
  ("\\subsubsection{%s}" . "\\subsubsection*{%s}"))
#+END_SRC

Both these classes have to be added to ~org-latex-classes~ like so:
#+NAME: org-latex-classes
#+BEGIN_SRC emacs-lisp :noweb yes
(eval-after-load "ox-latex"
  '(progn
     (add-to-list 'org-latex-classes

Another great features of Org-mode is the Org projects that allow the user to
easily publish a bunch of org files to a remote location. Here is the current
declaration of my projects, which will be detailed later:
#+NAME: org-publish-projects
#+BEGIN_SRC emacs-lisp :noweb yes

**** Configuration website
:PROPERTIES:
:CUSTOM_ID: Packages-Configuration-Org-mode-Projects-Configuration-websitelki5fl6184j0
:END:
This is my configuration for exporting my dotfiles to my website in a web format
only. No PDFs or anything, just HTML. Please note that I do not use that often
anymore, I much prefer the automatic script that I have which deploys through my
Drone instance my website on git pushes.

And before we get into the actual configuration, I would like to introduce a
couple of variables. This is a bit more verbose than if I declared everything
manually, but now I can change all three values at the same time without a
hasle.
#+NAME: org-proj-config-setup
#+BEGIN_SRC emacs-lisp
(defvar phundrak//projects-config-target
  "/ssh:Tilo:~/www/phundrak.com/config"
  "Points to where exported files for config.phundrak.com should be put.")
(defvar phundrak//projects-config-source
  "~/org/config/"
  "Points to where the sources for config.phundrak.com are.")
(defvar phundrak//projects-config-language
  "en"
  "Language of the website config.phundrak.com.")
(defvar phundrak//projects-config-recursive
  t
  "Defines whether subdirectories should be parsed for config.phundrak.com.")
#+END_SRC

Now, here is my configuration. In this snippet, my org files located in my
source directory get exported in the HTML format and published to my target
directory on my remote server through RSYNC via TRAMP. A sitemap is
automatically generated, which comes in handy with the online sitemap that is
available through the navigation bar.
#+NAME: org-proj-config-html
#+BEGIN_SRC emacs-lisp
("config-website-org"
 :base-directory ,phundrak//projects-config-source
 :base-extension "org"
 :publishing-directory ,phundrak//projects-config-target
 :recursive ,phundrak//projects-config-recursive
 :language ,phundrak//projects-config-language
 :publishing-function org-html-publish-to-html
 :headline-levels 5
 :auto-sitemap t
 :auto-preamble t)
#+END_SRC

We also have the component for all the static files needed to run the website
(mostly images tbh).
#+NAME: org-proj-config-static
#+BEGIN_SRC emacs-lisp
("config-website-static"
 :base-directory ,phundrak//projects-config-source
 :base-extension "png\\|jpg\\|gif\\|webp\\|svg\\|jpeg\\|ttf\\|woff\\|txt\\|epub\\|md"
 :publishing-directory ,phundrak//projects-config-target
 :recursive ,phundrak//projects-config-recursive
 :language ,phundrak//projects-config-language
 :publishing-function org-publish-attachment)
#+END_SRC

The project is then defined like so:
#+NAME: org-proj-config
#+BEGIN_SRC emacs-lisp
("config-website"
 :components ("config-website-org"
              "config-website-static"))
#+END_SRC

/Conlangs/, or /constructed languages/, are artificial languages created

which evolve and appear naturally from other languages.
#+end_info

My conlanging website is made out of three projects. As for the
previous project, let’s declare the common values for these.
#+NAME: org-proj-lang-setup
#+BEGIN_SRC emacs-lisp
(defvar phundrak//projects-conlanging-target
  "/rsync:Tilo:~/www/phundrak.com/conlang"
  "Points to where exported files for langue.phundrak.com should be put.")
(defvar phundrak//projects-conlanging-source
  "~/Documents/conlanging/content/"
  "Points to where the sources for langue.phundrak.com are.")
(defvar phundrak//projects-conlanging-language
  "en"
  "Language of langue.phundrak.com.")
(defvar phundrak//projects-conlanging-recursive
  t
  "Defines whether subdirectories should be parsed for langue.phundrak.com.")
#+END_SRC

The first component is the one generating the HTML files from the org files.
#+NAME: org-proj-lang-html
#+BEGIN_SRC emacs-lisp

While most modes of Emacs are dedicated to development, and therefore
are much more comfortable with a fixed-pitch font, more literary modes
such as org-mode are much more enjoyable if you have a variable pitch
font enabled. *BUT*, these modes can also require some fixed-pitch fonts
for some elements of the buffer, such as code blocks with
org-mode. ~mixed-pitch~ comes to the rescue!

I have an issue with org-mode’s emphasis markers: I find them ugly. I
can of course hide them if I simply set ~org-hide-emphasis-markers~ to
~t~, but it makes editing hard since I never know whether I am before or
after the emphasis marker when editing near the beginning/end of an
emphasized region. ~org-appear~ fixes this issue so that it shows the
emphasis markers only when the cursor is in the emphasized region,
otherwise they will remain hidden! Very cool!

*** DSLs

DSLs, or /Domain Specific Languages/, are languages dedicated to some

[[https://caddyserver.com/][Caddy]] (or /Caddyserver/) is a web server akin to Nginx or Apache which I
find much easier to configure that the latter two, plus it has
built-in support for automatically generating SSL certificates with
Letsencrypt! Automatic HTTPS, what more do you want?

All that is nice and all, but Emacs doesn’t support the syntax of
Caddy files natively, so let’s install ~caddyfile-mode~:

be built. It is not as standard as some other tools such as automake,
autoconfig, and the likes, but still pretty standard. CMake however
doesn’t have a major mode available by default, so let’s provide one.
#+begin_src emacs-lisp

I know, I know, C and C++ no longer are closely related languages,
each one of them went their own way and learning C won’t make you a
good C++ programmer, neither will the other way around. But, They are
still somewhat related, and Emacs thinks so too.

My current window manager is StumpWM, inspired by Emacs and written in

Ahem…

The package ~all-the-icons~ allows us to use a wide variety of icons in
Emacs for various purposes, wherever we want, and /THAT/ is *GREAT*! I’ll
(ab)use this feature in my config, be warned! *NOTE*: The first time a
configuration with ~all-the-icons~ loads on a machine, the needed fonts
might not be available, so you’ll need to install them with the
command ~M-x all-the-icons-install-fonts~.
#+begin_src emacs-lisp

#+end_src

~prettify-symbols-mode~ is also a nifty feature of Emacs, and it is
built-in! With that, I can replace strings of my choice by another
character of my choice! First, let’s declare the general symbols that
will be used everywhere.
#+begin_src emacs-lisp


(defun prog-mode-set-symbols-alist ()
  (setq prettify-symbols-alist '(("lambda"  . ?λ)
                                 ("null"    . ?∅)
                                 ("NULL"    . ?∅)))
  (prettify-symbols-mode 1))

(add-hook 'prog-mode-hook #'prog-mode-set-symbols-alist)
#+end_src

We can now take care of the language-specific symbols. First, let’s
declare some symbols for the Lisp languages.
#+begin_src emacs-lisp
(setq-default lisp-prettify-symbols-alist '(("lambda"    . ?λ)
                                            ("defun"     . ?𝑓)
                                            ("defvar"    . ?𝑣)
                                            ("defcustom" . ?𝑐)
                                            ("defconst"  . ?𝐶)))

(defun lisp-mode-prettify ()
  (setq prettify-symbols-alist lisp-prettify-symbols-alist)
  (prettify-symbols-mode -1)
  (prettify-symbols-mode 1))

  (add-hook (intern (format "%S-mode-hook" lang))
            #'lisp-mode-prettify))
#+end_src

Finally, similar to how ~org-appear~ behaves, let’s show the real string
of our symbols when the cursor is on it.

*** Pixel-perfect alignment of Markdown and org-mode tables
:PROPERTIES:
:CUSTOM_ID: Packages-Configuration-Visual-Configuration-Pixel-perfect-alignment-of-Markdown-and-org-mode-tables-u9rjl661bdj0
:END:
Usually, I have no issue with the alignment of the tables I write in
org-mode and (more rarely) Markdown. However, there are occurences
where I’ll use a character that does not exactly respect my monospace
font, which messes with the alignment of the table (often when I do
linguistics stuff). A solution to this is the package ~valign~. A little
caveat though, as its name implies ~valign~ helps with vertical
alignment. If some lines are too high, they won’t exactly fit. Unless?
Unless ~valign-fancy-bar~ is set to ~t~.

For now, I disabled the hook with org-mode and markdown-mode because
it slows down opening these files quite a lot. I’ll re-enable the hook
once it is fixed.

A common issue when you have a lot of windows opened in Emacs is
sometimes there’s just too much. Is the first window source code? Is
the other one just an open email? Oh, let’s not forget the ~*Messages*~
buffer open next to another source buffer.

Solaire-mode applies a subtle but useful tweak to your current color
scheme: the background of programming buffers is slightly lighter than
the background of other buffers. (Or is it other buffers that have a
slightly darker background? I’m not sure.)
