* Introduction

*STOP* Read this first!

You just landed on my vanilla Emacs configuration. However, this URL
was used until recently for my Spacemacs configuration. If you want my
complete, working Emacs configuration, I recommend you to head over
there. /*This document is still a work in progress!*/
#+end_center

After a couple of years using Spacemacs and a failed attempt at
switching to DoomEmacs, I’m finally switching back to a vanilla
configuration! Be aware though this document is still very much a work
in progress document, lots of comments on existing configuration are
missing, and lots of functionnalities are still not implemented. I’m
still in the process of porting my [[file:spacemacs.org][Spacemacs]] configuration over here.

** Early Init
:PROPERTIES:
:CUSTOM_ID: Basic-configuration-Early-Inityj7iel6184j0
:END:
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.
#+headers: :exports code :results silent :lexical t

** 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
would usually be considered by Emacs a word can be understood as
several modes, as in camelCase words, and allows us to jump words on
this finer level.
#+begin_src emacs-lisp
(global-subword-mode 1)
#+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 tangeant 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 anyways, 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 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
#+headers: :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 acces.
#+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

I’m also interested in keeping track of how fast Emacs loads on my
computer, as well as for how long I keep it open. The values are
stored in a ~.csv~ with three columns:
- The date when Emacs was closed
- Emacs’ init time
- Emacs’ uptime
#+begin_src emacs-lisp
(defvar my/emacs-log-file-time (expand-file-name "emacs-time.csv" user-emacs-directory))

(defun my/write-emacs-loadtime-and-uptime ()
  (with-temp-buffer
    (find-file my/emacs-log-file-time)
    (goto-char (point-max))
    (insert (format "%s,%s,%s\n"
                    (string-trim (shell-command-to-string "date +%F-%H-%M-%S"))
                    (emacs-init-time "%f")
                    (emacs-uptime "%dd %hh %mm %ss")))
    (save-buffer)))

(add-to-list 'kill-emacs-hook #'my/write-emacs-loadtime-and-uptime)
#+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
(set-frame-parameter (selected-frame) 'alpha-background 0.8)
#+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

don’t. I prefer [[https://github.com/microsoft/cascadia-code][Cascadia Code]], as it also somewhat supports the [[https://www.internationalphoneticassociation.org/][IPA]].
#+begin_src emacs-lisp
(defvar phundrak/default-font-size 90

** 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"
  (declare (indent defun) (debug t))
  (if (symbolp package)
      (list (if (or (not (bound-and-true-p byte-compile-current-file))
                    (require package nil 'noerror))

              #'with-no-warnings)
            ;; We intentionally avoid `with-eval-after-load' to prevent eager
            ;; macro expansion from pulling (or failing to pull) in autoloaded

            `(eval-after-load ',package ',(macroexp-progn body)))
    (let ((p (car package)))

             `(after! (:and ,@package) ,@body))
            ((memq p '(:or :any))

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 /Elpa/ repository has been renamed to
the /gnu/ repository 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 were renamed in order to avoid any
confusion between the two of them.

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 is
also supported by ~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.

** 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.

As seen below, I use ~org-msg~ to compose my emails, which includes by

Mu4e is a very eye-pleasing email client for Emacs, built around ~mu~
and which works very 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
configuration for the ~mu4e~ package itself.

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]].

First, let’s inform Emacs how it can send emails, using which service
and how. In my case, I use my own mail server.

***** 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

Next I need an inbox dedicated to the association I’m part of.
#+name: mu4e-bookmarks-filter-asso
#+headers: :tangle no :cache yes
#+begin_src emacs-lisp

As for the Emacs-doctor list, I need to match both the current, modern
mailing list address but also its old address.
#+name: mu4e-bookmarks-filter-emacs-list
#+headers: :tangle no :cache yes
#+begin_src emacs-lisp

Another bookmark I wish to have is one dedicated to emails related to
issues and PRs from Github.
#+name: mu4e-bookmarks-filter-github-list
#+headers: :tangle no :cache yes

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.

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:

***** Dealing with spammers

:END:
I’m sure you have received at least one email recently from a sketchy
email address asking you something that might be completely unrelated
to what you do, or at least somewhat related. Fortunately, [[https://twitter.com/Boris/status/1360208504544444417][we have a
hero]]! Now, let me write a function that will insert their pre-written
text at point so I don’t have to go back to their Twitter thread each
time I want to shut spammers up.
#+begin_src emacs-lisp
(defun reply-to-bill ()
  (interactive)
  (insert "Please forward this email to bill@noprocurement.com,
and delete my email, as I’ll be changing jobs soon, and this
email address will no longer be active.

Bill Whiskoney is a senior partner at Nordic Procurement
Services, and he handles our budget and will help you further or
introduce you to someone who can."))
#+end_src

If you want the full story, make sure to read the whole thread, I
guarantee it, it’s worth your time! And in case the Twitter thread
disappear in the future, [[https://threader.app/thread/1360208504544444417][here is a backup]].

***** Getting Fancy

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~.

***** Keybindings

:END:
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
  :packages 'mu4e

  "gu"  nil)

(phundrak/undefine
  :keymaps '(mu4e-view-mode-map mu4e-headers-mode-map)
  :packages 'mu4e
  "s"   nil)
#+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:
#+name: mu4e-keybindings-view-tbl

  :packages 'mu4e
  <<general-keybindings-gen(table=mu4e-keybindings-view-tbl)>>)
#+end_src

Two other keybinds are added without a prefix, just for the sake of
convenience.
#+name: mu4e-keybindings-view-no-prefix
#+begin_src emacs-lisp
(phundrak/evil

#+end_src

I’ll also declare two keybinds for mu4e’s headers mode.
#+name: mu4e-keybindings-header
#+begin_src emacs-lisp :tangle no
(phundrak/major-leader-key
  :keymaps 'mu4e-headers-mode-map
  :packages 'mu4e
  "t" '(mu4e-view-mark-thread :which-key "mark thread")
  "s" 'swiper)
#+end_src

I will also redefine without a leader key ~ctsr~ in order to be able to
move freely (remember, bépo layout for me).
#+name: mu4e-keybindings-header-no-leader
#+begin_src emacs-lisp :tangle no
(phundrak/evil
  :keymaps 'mu4e-headers-mode-map

  "c" #'evil-backward-char
  "t" #'evil-next-line
  "s" #'evil-previous-line
  "r" #'evil-forward-char)
#+end_src

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.
#+name: mu4e-keybindings-message-tbl
| Key | Function              | Description |

~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.

*** Writeroom

:CUSTOM_ID: Packages-Configuration-Editing-Writeroomxt12fl6184j0

On the other hand, ~writeroom~ allows the user to enter a
distraction-free mode of Emacs, and I like that! But the default width
is a bit too small for me, and I prefer not to go fullscren.

*** 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.
#+begin_src emacs-lisp
(use-package dired
  :straight (:type built-in)
  :defer t
  :hook (dired-mode . turn-on-gnus-dired-mode)
  :general

  :config
  (setq dired-dwim-target       t

        dired-recursive-deletes t
        dired-listing-switches  "-ahl --group-directories-first"))
#+end_src

Note that I am activating by default ~gnus-dired-mode~. This is just for
the sake of convenience, since I’m not penalized with activating this
mode when it is not needed, but I don’t have to manually activate it
each time I need it.

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
  :straight (:type built-in)
  :after dired
  :commands (dired-jump dired-jump-other-window dired-omit-mode)
  :general
  (phundrak/evil
    :keymaps 'dired-mode-map
    :packages 'dired-x
    "«" #'dired-omit-mode))
#+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
  :after dired
  :straight (:build t)
  :general
  (phundrak/evil
   :keymaps 'dired-mode-map
   :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)
  :hook (dired-after-reading . dired-git-info-auto-enable)

    ")" #'dired-git-info-mode)
  :config
  (setq dgi-auto-hide-details-p t))
#+end_src

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

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

*** 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
:PROPERTIES:
:CUSTOM_ID: Packages-Configuration-Emacs-built-ins-Eshell0662fl6184j0
:END:
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.
#+begin_src emacs-lisp
(use-package eshell
  :defer t
  :straight (:type built-in :build t)
  :general
  (phundrak/evil
    :keymaps 'eshell-mode-map
    "c" #'evil-backward-char
    "t" #'evil-next-line

  (general-define-key
   :keymaps 'eshell-mode-map

  <<eshell-concat-shell-command>>
  <<eshell-alias-open>>
  <<eshell-alias-buffers>>
  <<eshell-alias-emacs>>
  <<eshell-alias-mkcd>>)
#+end_src

**** 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."
  (string-join 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.
#+begin_src emacs-lisp
(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)
  :general
  (:keymaps 'esh-autosuggest-active-map
   "C-e" #'company-complete-selection))
#+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
:PROPERTIES:
:CUSTOM_ID: Packages-Configuration-Emacs-built-ins-Eshell-Visual-configuratione7c2fl6184j0
:END:
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]]!
#+begin_src emacs-lisp

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

Another feature I like is fish-like syntax highlight, which brings
some more colors to Eshell.
#+begin_src emacs-lisp
(use-package eshell-syntax-highlighting
  :after (esh-mode eshell)
  :defer t
  :straight (:build t)
  :config
  (eshell-syntax-highlighting-global-mode +1))
#+end_src

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.
#+begin_src emacs-lisp
(use-package powerline-eshell

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:
[[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-args ("-c"))))
#+end_src

I’ll also create a fuction for connecting to this new Tramp protocol:
#+begin_src emacs-lisp
(defun my/yadm ()
  "Manage my dotfiles through TRAMP."
  (interactive)
  (magit-status "/yadm::"))

Bufler is a package that organizes and lists buffers in a much better

** Org-mode
:PROPERTIES:
:CUSTOM_ID: Packages-Configuration-Org-modedw35fl6184j0

Since recently, in order to make ~org-cite~ compile properly, we need
the ~citeproc~ package, a citation processor.
#+begin_src emacs-lisp
(use-package citeproc
  :after (org)
  :defer t
  :straight (:build t))
#+end_src

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.

This package is a small package I’ve written that helps me when
writing conlanging documents, with features such as creating syntax
trees, converting translitterated text to its native script, etc…
#+begin_src emacs-lisp

  :after org

#+end_src

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.
#+begin_src emacs-lisp
(use-package org-contrib

A package I use from time to time is ~ob-latex-as-png~ which allows me
to easily convert a LaTeX snippet into a PNG, regardless of the
exporter I use afterwards. Its installation is pretty simple:
#+begin_src emacs-lisp
(use-package ob-latex-as-png
  :after org
  :straight (:build t)
  :defer t
  :init
  (add-to-list 'org-babel-load-languages '(latex-as-png . t)))

#+end_src

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:
#+NAME: org-babel-languages-table
| C          |
| dot        |
| emacs-lisp |
| gnuplot    |

| makefile   |
| sass       |
| shell      |

#+NAME: org-babel-languages-gen
#+header: :cache yes :results replace
#+header: :var languages=org-babel-languages-table[,0]
#+BEGIN_SRC emacs-lisp :exports none :tangle no

        (mapconcat (lambda ($language)
                     (format "(%s . t)" $language))
                   languages
                   "\n  "))
#+END_SRC

*** Behavior
:PROPERTIES:
:CUSTOM_ID: Packages-Configuration-Org-mode-Behaviorzp65fl6184j0
:END:
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
(use-package toc-org
  :after (org markdown-mode)
  :straight (:build t)
  :init
  (add-to-list 'org-tag-alist '("TOC" . ?T))
  :hook (org-mode . toc-org-enable)
  :hook (markdown-mode . toc-org-enable))
#+end_src

~electric-mode~ also bothers me a lot when editing org files, so let’s deactivate it:
#+name: org-behavior-electric
#+begin_src emacs-lisp :tangle no
(add-hook 'org-mode-hook (lambda ()
                           (interactive)
                           (electric-indent-local-mode -1)))
#+end_src

As explained in my [[https://blog.phundrak.com/better-custom-ids-orgmode/][blog post]], org-mode is terrible with coming up with
meaningful IDs for its headings. I actually wrote a package for this!
#+begin_src emacs-lisp
(use-package org-unique-id
  :straight (org-unique-id :build t
                           :type git

                           :repo "Phundrak/org-unique-id")
  :defer t
  :after org
  :init
  (add-hook 'org-mode-hook
     (lambda ()
       (add-hook 'before-save-hook
                 (lambda ()
                   (when (and (eq major-mode       'org-mode)
                              (eq buffer-read-only nil))
                     (org-unique-id)))))))
#+end_src

*** 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
(setq org-use-sub-superscripts (quote {}))
#+END_SRC

**** Epub
:PROPERTIES:
:CUSTOM_ID: Packages-Configuration-Org-mode-File-export-Epub-w5ycfuz095j0
:END:
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]].
#+begin_src emacs-lisp
(use-package ox-epub
  :after (org ox)
  :straight (:build t))
#+end_src

**** HTML
:PROPERTIES:
:CUSTOM_ID: Packages-Configuration-Org-mode-File-export-HTMLxjc5fl6184j0
:END:
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
#+BEGIN_SRC emacs-lisp :tangle no
(setq org-html-validation-link nil)
#+END_SRC

#+begin_src emacs-lisp
;; (use-package htmlize
;;   :defer t
;;   :straight (:build t))
#+end_src

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
  :defer t
  :after (org)
  :straight (preview-org-html-mode :build t
                                   :type git
                                   :host github
                                   :repo "jakebox/preview-org-html-mode")

#+end_src

**** LaTeX
:PROPERTIES:
:CUSTOM_ID: Packages-Configuration-Org-mode-File-export-LaTeXg2b5fl6184j0
:END:
When it comes to exports, I want the LaTeX and PDF exports to be done
with XeLaTeX only. This implies the modification of the following
variable:
#+NAME: org-latex-compiler
#+BEGIN_SRC emacs-lisp :tangle no
(setq org-latex-compiler "xelatex")
#+END_SRC

I also want to get by default ~minted~ for LaTeX listings so I can have
syntax highlights:
#+NAME: org-latex-listings
#+BEGIN_SRC emacs-lisp :tangle no
(setq org-latex-listings 'minted)
#+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
#+BEGIN_SRC emacs-lisp :tangle no
(dolist (package '(("AUTO" "inputenc" t ("pdflatex"))
                   ("T1"   "fontenc"  t ("pdflatex"))
                   (""     "grffile"  t)))
  (delete package org-latex-default-packages-alist))

(dolist (package '((""           "minted")
                   ("capitalize" "cleveref")
                   (""           "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

**** Markdown
:PROPERTIES:
:CUSTOM_ID: Packages-Configuration-Org-mode-File-export-Markdown-g2vh5vz095j0
:END:
There’s not really any unified Markdown specification, meaning
everyone can pretty much do whatever they want with the syntax and
still call it Markdown. Great… But something I appreciate is Github
supports some extra HTML to make our files extra spicy! And lucky me,
there’s a package for exporting my org files to Github-flavored
Markdown!
#+begin_src emacs-lisp
(use-package ox-gfm
  :after (ox org)
  :straight (:build t))
#+end_src

**** Reveal.js

  :config
  (setq org-re-reveal-root "https://cdn.jsdelivr.net/npm/reveal.js"
        org-re-reveal-revealjs-version "4"))
#+end_src

**** SSH Config
:PROPERTIES:
:CUSTOM_ID: Packages-Configuration-Org-mode-File-export-SSH-Config-tatextz095j0
:END:
Yet another exporter I enjoy is [[https://github.com/dantecatalfamo/ox-ssh][~ox-ssh~]] with which I manage my
~$HOME/.ssh/config~ file. You won’t find my org file for managing my
servers on my repos though.

*** Keybindings
:PROPERTIES:
:CUSTOM_ID: Packages-Configuration-Org-mode-Keybindingsv0e5fl6184j0

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

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
| Key chord | Function                | Description |

| 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 |
|-----------+-------------------------------+-------------|

*** 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
                  <<org-latex-class-conlang>>)
     (add-to-list 'org-latex-classes
                  <<org-latex-class-beamer>>)))
#+END_SRC

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
<<org-proj-config-setup>>
<<org-proj-lang-setup>>
(setq org-publish-project-alist
      `(

        <<org-proj-config-static>>
        <<org-proj-config>>
        <<org-proj-lang-html>>
        <<org-proj-lang-pdf>>
        <<org-proj-lang-static>>
        <<org-proj-lang>>))

**** 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

**** Linguistics website
:PROPERTIES:
:CUSTOM_ID: Packages-Configuration-Org-mode-Projects-Linguistics-websitey4k5fl6184j0

My linguistics 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

  "/ssh:Tilo:~/www/phundrak.com/langue/"

  "Points to where the sources for langue.phundrak.com are")

  "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
("langue-phundrak-com-org"
 :base-directory ,phundrak//projects-conlanging-source

 :publishing-function org-html-publish-to-html
 :headline-levels 5
 :auto-sitemap t

#+END_SRC

We also have the component for the LaTeX and PDF part of the website:
#+NAME: org-proj-lang-pdf
#+BEGIN_SRC emacs-lisp
("langue-phundrak-com-pdf"
 :base-directory ,phundrak//projects-conlanging-source

 :language ,phundrak//projects-conlanging-language
 :publishing-function org-latex-publish-to-pdf
 :headline-levels 5
 :auto-preamble t)
#+END_SRC

And lastly, we have the component for all the static files needed to run the
website:
#+NAME: org-proj-lang-static
#+BEGIN_SRC emacs-lisp
("langue-phundrak-com-static"
 :base-directory ,phundrak//projects-conlanging-source

 :recursive ,phundrak//projects-conlanging-recursive
 :language ,phundrak//projects-conlanging-language
 :publishing-function org-publish-attachment)
#+END_SRC

The project is then defined like so:
#+NAME: org-proj-lang
#+BEGIN_SRC emacs-lisp
("langue-phundrak-com"
 :components ("langue-phundrak-com-org"
              "langue-phundrak-com-static"

*** Visual Configuration
:PROPERTIES:
:CUSTOM_ID: Packages-Configuration-Org-mode-Visual-Configurationrol5fl6184j0
:END:
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!
#+begin_src emacs-lisp

With this, I also use ~org-pretty-tables~ in order to use some
capabilities of Unicode in order to make tables nicer to look at.

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!
#+begin_src emacs-lisp

  :after org
  :straight (:build t)

Similarly, LaTeX fragments previews are nice and all, but if I have my
cursor on it, I want to see the LaTeX source code and modify it, not
just the generated image!

Tired of seeing lots of actual stars ~*~ in your headers, and you want a

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~ is loaded 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
(use-package all-the-icons
  :defer t
  :straight t)
#+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!
#+begin_src emacs-lisp

                  ("mapc" . 8614)))
  (add-to-list 'prettify-symbols-alist symbol))
