Introduction
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:
Emacs is a great operating system, it just lacks a good text editor.
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
This configuration makes heavy use of the 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:
(defun hello ()
<<generate-docstring()>>
<<print-hello>>)Will instead appear as
(defun hello ()
<<generate-docstring()>>
<<print-hello>>)
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.
(concat "\""
"Print \\\"Hello World!\\\" in the minibuffer."
"\"")
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.
(message "Hello World!")Basic Configuration
Early Init
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.
(setq package-enable-at-startup nil
inhibit-startup-message t
frame-resize-pixelwise t ; fine resize
package-native-compile t) ; native compile packages
(scroll-bar-mode -1) ; disable scrollbar
(tool-bar-mode -1) ; disable toolbar
(tooltip-mode -1) ; disable tooltips
(set-fringe-mode 10) ; give some breathing room
(menu-bar-mode -1) ; disable menubar
(blink-cursor-mode 0) ; disable blinking cursor
(setq gc-cons-threshold (* 1024 1024 1024))Emacs Behavior
Editing Text in Emacs
I never want to keep trailing spaces in my files, which is why I’m doing this:
(add-hook 'before-save-hook #'whitespace-cleanup)I don’t understand why some people add two spaces behind a full stop, I sure don’t. Let’s tell Emacs.
(setq-default sentence-end-double-space nil)
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.
(global-subword-mode 1)
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.
(setq scroll-conservatively 1000)Lastly, I want the default mode for Emacs to be Emacs Lisp.
(setq-default initial-major-mode 'emacs-lisp-mode)Indentation
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:
(setq-default indent-tabs-mode nil)
(add-hook 'prog-mode-hook (lambda () (setq indent-tabs-mode nil)))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?
Tabs for indentation
Spaces for alignment
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
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.
| Modes |
|---|
| prog-mode |
| latex-mode |
(mapconcat (lambda (mode) (format "%s-hook" (car mode)))
modes
" ")Line Number
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.
(dolist (mode '(<<prog-modes-gen()>>))
(add-hook mode #'display-line-numbers-mode))Folding code
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:
(dolist (mode '(<<prog-modes-gen()>>))
(add-hook mode #'hs-minor-mode))Stay Clean, Emacs!
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.
(setq backup-directory-alist `(("." . ,(expand-file-name ".tmp/backups/"
user-emacs-directory))))
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?
(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))If we delete a file, we want it moved to the trash, not simply deleted.
(setq delete-by-moving-to-trash t)Finally, the scatch buffer always has some message at its beginning, I don’t want it!
(setq-default initial-scratch-message nil)Stay Polite, Emacs!
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.
(defalias 'yes-or-no-p 'y-or-n-p)
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:
(global-auto-revert-mode 1)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
Let’s raise Emacs undo memory to 10MB, and make Emacs auto-save our files by default.
(setq undo-limit 100000000
auto-save-default t)(setq window-combination-resize t) ; take new window space from all other windowsPersonal Information
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.
(setq user-full-name "Lucien Cartier-Tilet"
user-real-login-name "Lucien Cartier-Tilet"
user-login-name "phundrak"
user-mail-address "lucien@phundrak.com")Visual Configuration
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.
(setq visible-bell t)It is nicer to see a cursor cover the actual space of a character.
(setq x-stretch-cursor t)When text is ellipsed, I want the ellipsis marker to be a single character of three dots. Let’s make it so:
(with-eval-after-load 'mule-util
(setq truncate-string-ellipsis "…"))
With Emacs 29.0.50 onwards, a new frame parameter exists:
alpha-background. Unlike alpha, this frame parameter only makes Emacs’
background transparent, excluding images and text.
(add-to-list 'default-frame-alist '(alpha-background . 0.9))Modeline Modules
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).
(require 'time)
(setq display-time-format "%Y-%m-%d %H:%M")
(display-time-mode 1) ; display time in modelineSomething 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.
(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)))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:
(column-number-mode)
The following code is, as will several chunks of code in this config,
borrowed from 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.
(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)))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.
(add-hook 'after-change-major-mode-hook #'modeline-contitional-buffer-encoding)Fonts
I don’t like the default font I usually have on my machines, I really don’t. I prefer Cascadia Code, as it also somewhat supports the IPA.
(defvar phundrak/default-font-size 90
"Default font size.")
(defvar phundrak/default-font-name "Cascadia Code"
"Default font.")
(defun my/set-font ()
(when (find-font (font-spec :name phundrak/default-font-name))
(set-face-attribute 'default nil
:font phundrak/default-font-name
:height phundrak/default-font-size)))
(my/set-font)
(add-hook 'server-after-make-frame-hook #'my/set-font)Frame Title
This is straight-up copied from TEC’s configuration. See their comment on the matter.
(setq frame-title-format
'(""
"%b"
(:eval
(let ((project-name (projectile-project-name)))
(unless (string= "-" project-name)
(format (if (buffer-modified-p) " ◉ %s" " ● %s - Emacs") project-name))))))A better custom variable setter
Something people often forget about custom variables in Elisp is they
can have a custom setter that will run some code if we set the
variable properly with customize-set-variable, so setq shouldn’t be
the user’s choice by default. But repeatedly writing
customize-set-variable can get tiring and boring. So why not take the
best of both world and create csetq, a setq that uses
customize-set-variable under the hood while it keeps a syntax similar
to the one setq uses?
(defmacro csetq (&rest forms)
"Bind each custom variable FORM to the value of its VAL.
FORMS is a list of pairs of values [FORM VAL].
`customize-set-variable' is called sequentially on each pairs
contained in FORMS. This means `csetq' has a similar behaviour as
`setq': each VAL expression are evaluated sequentially, i.e. the
first VAL is evaluated before the second, and so on. This means
the value of the first FORM can be used to set the second FORM.
The return value of `csetq' is the value of the last VAL.
\(fn [FORM VAL]...)"
(declare (debug (&rest sexp form))
(indent 1))
;; Check if we have an even number of arguments
(when (= (mod (length forms) 2) 1)
(signal 'wrong-number-of-arguments (list 'csetq (1+ (length forms)))))
;; Transform FORMS into a list of pairs (FORM . VALUE)
(let (sexps)
(while forms
(let ((form (pop forms))
(value (pop forms)))
(push `(customize-set-variable ',form ,value)
sexps)))
`(progn ,@(nreverse sexps))))I first got inspired by this blog article (archived article, just in case) but it seems the code snippet no longer works properly, so not only did I have to modify it to make it work with an arbitrary amount of arguments (as long as it’s pairs of variables and their value), but I also had to make the code simply work.
Custom Elisp
Dired functions
phundrak/open-marked-files
This function allows the user to open all marked files from a dired buffer as new Emacs buffers.
(defun phundrak/open-marked-files (&optional files)
"Open all marked FILES in Dired buffer as new Emacs buffers."
(interactive)
(let* ((file-list (if files
(list files)
(if (equal major-mode "dired-mode")
(dired-get-marked-files)
(list (buffer-file-name))))))
(mapc (lambda (file-path)
(find-file file-path))
(file-list))))Switch between buffers
Two default shortcuts I really like from Spacemacs are SPC b m and SPC
b s, which bring the user directly to the *Messages* buffer and the
*scratch* buffer respectively. These functions do exactly this.
(defun switch-to-messages-buffer ()
"Switch to Messages buffer."
(interactive)
(switch-to-buffer (messages-buffer)))
(defun switch-to-scratch-buffer ()
"Switch to Messages buffer."
(interactive)
(switch-to-buffer "*scratch*"))Screenshots
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 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 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.
(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)))I used this function to take the screenshots you can see in this document.
Handle new windows
The two functions below allow the user to not only create a new window to the right or below the current window (respectively), but also to focus the new window immediately.
(defun split-window-right-and-focus ()
"Spawn a new window right of the current one and focus it."
(interactive)
(split-window-right)
(windmove-right))
(defun split-window-below-and-focus ()
"Spawn a new window below the current one and focus it."
(interactive)
(split-window-below)
(windmove-down))
(defun kill-buffer-and-delete-window ()
"Kill the current buffer and delete its window."
(interactive)
(progn
(kill-this-buffer)
(delete-window)))
Extend add-to-list
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:
(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)))))Package Management
Repositories
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.
(setq package-archives '(("melpa" . "https://melpa.org/packages/")
("gnu" . "https://elpa.gnu.org/packages/")
("nongnu" . "https://elpa.nongnu.org/nongnu/")))Straight
For my package management, I prefer to use straight (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.
(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))Now, we can refresh our package list in order to be able to install stuff.
(package-initialize)
(unless package-archive-contents
(package-refresh-contents))
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:
(setq straight-host-usernames
'((github . "Phundrak")
(gitlab . "Phundrak")))
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.
(setq straight-vc-git-default-remote-name "straight")
We finally come to the use-package installation. This is done like so:
(straight-use-package '(use-package :build t))
(setq use-package-always-ensure t)Keybinding Management
Which-key
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.
(use-package which-key
:straight (:build t)
:defer t
:init (which-key-mode)
:diminish which-key-mode
:config
(setq which-key-idle-delay 1))General
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.

table
"\n")Evil
Evil emulates most of vim’s keybinds, because let’s be honest here, they are much more comfortable than Emacs’.
(use-package evil
:straight (:build t)
:after (general)
:init
(setq evil-want-integration t
evil-want-keybinding nil
evil-want-C-u-scroll t
evil-want-C-i-jump nil)

(evil-mode 1)
(setq evil-want-fine-undo t) ; more granular undo with evil
(evil-set-initial-state 'messages-buffer-mode 'normal)
(evil-set-initial-state 'dashboard-mode 'normal))
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.
(evil-global-set-key 'motion "t" 'evil-next-visual-line)
(evil-global-set-key 'motion "s" 'evil-previous-visual-line)
(general-define-key

"C-a" nil
"C-y" nil
"C-e" nil)
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.
(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
:states 'motion
"h" 'evil-replace
"H" 'evil-replace-state
"j" 'evil-find-char-to
"J" 'evil-find-char-to-backward
"k" 'evil-substitute

"l" 'evil-change

"T" 'evil-join
"s" 'evil-previous-visual-line
"S" 'evil-lookup
"r" 'evil-forward-char
"R" 'evil-window-bottom)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.
(use-package evil-collection
:after evil
:straight (:build t)
:config
;; bépo conversion
(defun my/bépo-rotate-evil-collection (_mode mode-keymaps &rest _rest)

"j" "t"
"k" "s"
"l" "r"))
(add-hook 'evil-collection-setup-hook #'my/bépo-rotate-evil-collection)
(evil-collection-init))
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.
(use-package undo-tree
:defer t
:straight (:build t)

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.
(when (executable-find "zstd")
(defun my/undo-tree-append-zst-to-filename (filename)

Hydra is a simple menu creator for keybindings.
(use-package hydra
:straight (:build t)
:defer t)Hydras
The following hydra allows me to quickly zoom in and out in the current buffer.
(defhydra hydra-zoom ()
"
^Zoom^ ^Other
^^^^^^^--------------------------
[_t_/_s_] zoom in/out [_q_] quit
[_0_]^^ reset zoom
"
("t" text-scale-increase "zoom in")
("s" text-scale-decrease "zoom out")
("0" text-scale-adjust "reset")
("q" nil "finished" :exit t))
Similarly, this one is also inspired from Spacemacs and allows the
user to interact with the width of the buffer in writeroom.
(defhydra writeroom-buffer-width ()
"
^Width^ ^Other
^^^^^^^^-----------------------
[_t_] enlarge [_r_/_0_] adjust
[_s_] shrink [_q_]^^ quit

("q" nil :exit t)
("t" writeroom-increase-width "enlarge")
("s" writeroom-decrease-width "shrink")
("r" writeroom-adjust-width "adjust")
("0" writeroom-adjust-width "adjust"))
Another similar one is for mu4e-view-mode that allows me to shrink or
grow the mu4e-headers buffer when viewing an email.
(defhydra mu4e-headers-split-adjust-width ()
"
^Zoom^ ^Other
^^^^^^^---------------------------------
[_t_/_s_] shrink/enlarge view [_q_] quit
"
("q" nil :exit t)
("t" mu4e-headers-split-view-shrink "shrink")
("s" mu4e-headers-split-view-grow "enlarge"))Similarly still, this one allows me to manage the size my Emacs windows.
(defhydra windows-adjust-size ()
"
^Zoom^ ^Other
^^^^^^^-----------------------------------------
[_t_/_s_] shrink/enlarge vertically [_q_] quit
[_c_/_r_] shrink/enlarge horizontally
"
("q" nil :exit t)
("c" shrink-window-horizontally)
("t" enlarge-window)
("s" shrink-window)
("r" enlarge-window-horizontally))This one allows me to manipulate my Emacs frames’ background transparency.
(defun my/transparency-round (val)
"Round VAL to the nearest tenth of an integer."
(/ (round (* 10 val)) 10.0))
(defun my/increase-frame-alpha-background ()

Autocompletion
Code Autocompletion
Company is, in my opinion, the best autocompleting engine for Emacs, and it is one of the most popular if not the most popular.
(use-package company
:straight (:build t)

This package is a backend for company. It emulates
ac-source-dictionary by proposing text related to the current
major-mode.
(use-package company-dict
:after company
:straight (:build t)
:config
(setq company-dict-dir (expand-file-name "dicts" user-emacs-directory)))
On the other hand, company-box is a Company front-end which offers
colors, icons, documentation and so on. Very nice.
Declaring all the icons for the variable
company-box-icons-all-the-icons is quite verbose in Elisp, so I do it
with an org-table.

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.
(use-package ivy

There is also prescient.el that offers some nice features when
coupled with ivy, guess what was born out of it? ivy-prescient, of
course!
(use-package ivy-prescient
:after ivy
:straight (:build t))
I warned you I’d use too much all-the-icons, I did!
(use-package all-the-icons-ivy
:straight (:build t)
:after (ivy all-the-icons)
:hook (after-init . all-the-icons-ivy-setup))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?
(use-package ivy-posframe
:defer t
:after (:any ivy helpful)
:hook (ivy-mode . ivy-posframe-mode)

Finally, let’s make ivy richer:
(use-package ivy-rich
:straight (:build t)
:after ivy
:init
(ivy-rich-mode 1))Counsel
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.
(use-package counsel
:straight (:build t)
:after recentf
: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)))Yasnippet
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.
(use-package yasnippet
:defer t
:straight (:build t)
:init
(yas-global-mode)
:hook ((prog-mode . yas-minor-mode)
(text-mode . yas-minor-mode)))Of course, yasnippet wouldn’t be as awesome as it is without premade snippets.
(use-package yasnippet-snippets
:defer t
:after yasnippet
:straight (:build t))Similarly, yatemplate offers premade files rather than just strings. That’s still yasnippet by the way.
(use-package yatemplate
:defer t
:after yasnippet
:straight (:build t))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.

Bitwarden
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 Bitwarden CLI. Use at your own risks.
(use-package bitwarden

:type git
:host nil
:repo "https://labs.phundrak.com/phundrak/bitwarden.el"))Docker
Docker is an awesome tool for reproducible development environments. Due to this, I absolutely need a mode for editing Dockerfiles.
(use-package dockerfile-mode
:defer t
:straight (:build t)
:hook (dockerfile-mode . lsp-deferred)

The docker package also provides interactivity with Docker and
docker-compose from Emacs.
(use-package docker
:defer t
:straight (:build t))Elfeed
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.
(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))))
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 a neat package
for playing YouTube videos and friends through youtube-dl or its
superior fork yt-dlp in mpv.
(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)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.

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.

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

In the same vein of this bit of configuration, I do not want mu4e to
insert my mail signature, org-msg already does that.
(setq mu4e-compose-signature nil)Bookmarks
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 emacs-doctor mailing list (French Emacs mailing list)
- emails related to my internship
- 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).
(mapconcat (lambda (list)
(let ((address (string-replace (regexp-quote "~") "" (car list))))
(mapconcat (lambda (flag)
(concat flag ":" address))
'("list" "t" "f" "contact")
" OR ")))
lists
" OR ")(let ((regex "/.*up8\\.edu|.*univ-paris8.*/"))
(concat
<<mu4e-bookmarks-from-copy-to-gen>>
" OR maildir:/Univ/Inbox OR maildir:/Univ/Junk"))f:/.*up8\.edu|.*univ-paris8.*/ OR c:/.*up8\.edu|.*univ-paris8.*/ OR t:/.*up8\.edu|.*univ-paris8.*/ OR maildir:/Univ/Inbox OR maildir:/Univ/Junk
Next I need an inbox dedicated to the association I’m part of.
(let ((regex "/.*supran\\.fr/"))
<<mu4e-bookmarks-from-copy-to-gen>>)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 (see here). Here are the addresses to
match:
/ateliers.*emacs.*//emacs-.*@gnu.org//.*eshell-info-banner.*//.*emacsfr.*/
"<<mu4e-bookmarks-mailing-lists(lists=mu4e-emacs-mailing-lists)>>"list:/ateliers.*emacs.*/ OR t:/ateliers.*emacs.*/ OR f:/ateliers.*emacs.*/ OR contact:/ateliers.*emacs.*/ OR list:/emacs-.*@gnu.org/ OR t:/emacs-.*@gnu.org/ OR f:/emacs-.*@gnu.org/ OR contact:/emacs-.*@gnu.org/ OR list:/.*eshell-info-banner.*/ OR t:/.*eshell-info-banner.*/ OR f:/.*eshell-info-banner.*/ OR contact:/.*eshell-info-banner.*/ OR list:/.*emacsfr.*/ OR t:/.*emacsfr.*/ OR f:/.*emacsfr.*/ OR contact:/.*emacsfr.*/
Another bookmark I wish to have is one dedicated to emails related to more general development topics, including issues and PRs from Github.
/.*\\.github\\.com//.*\\.gitlab\\.com/stumpwm-devel@nongnu.org/.*sr\\.ht/
;; "<<mu4e-bookmarks-mailing-lists(lists=mu4e-github-mailing-lists)>> AND NOT ()"
(string-join '("<<mu4e-bookmarks-mailing-lists(lists=mu4e-github-mailing-lists)>>"
"AND NOT ("
<<mu4e-bookmarks-filter-emacs-list>>
")")
" ")list:/.*\.github\.com/ OR t:/.*\.github\.com/ OR f:/.*\.github\.com/ OR contact:/.*\.github\.com/ OR list:/.*\.gitlab\.com/ OR t:/.*\.gitlab\.com/ OR f:/.*\.gitlab\.com/ OR contact:/.*\.gitlab\.com/ OR list:stumpwm-devel@nongnu.org OR t:stumpwm-devel@nongnu.org OR f:stumpwm-devel@nongnu.org OR contact:stumpwm-devel@nongnu.org OR list:/.*sr\.ht/ OR t:/.*sr\.ht/ OR f:/.*sr\.ht/ OR contact:/.*sr\.ht/ AND NOT ( list:/ateliers.*emacs.*/ OR t:/ateliers.*emacs.*/ OR f:/ateliers.*emacs.*/ OR contact:/ateliers.*emacs.*/ OR list:/emacs-.*@gnu.org/ OR t:/emacs-.*@gnu.org/ OR f:/emacs-.*@gnu.org/ OR contact:/emacs-.*@gnu.org/ OR list:/.*eshell-info-banner.*/ OR t:/.*eshell-info-banner.*/ OR f:/.*eshell-info-banner.*/ OR contact:/.*eshell-info-banner.*/ OR list:/.*emacsfr.*/ OR t:/.*emacsfr.*/ OR f:/.*emacsfr.*/ OR contact:/.*emacsfr.*/ )
When it comes to my internship, all emails will contain an address containing aubay.com (that’s where my internship takes place).
/.*aubay.com/
(let ((regex "/.*aubay\\.com/"))
<<mu4e-bookmarks-from-copy-to-gen>>)f:/.*aubay\.com/ OR c:/.*aubay\.com/ OR t:/.*aubay\.com/
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:
(mapconcat #'identity
`("NOT flag:trashed"
,(format "(%s)" (mapconcat (lambda (maildir) (concat "maildir:" maildir))
'("/Inbox" "/Junk")
" OR ")))
" AND ")NOT flag:trashed AND (maildir:/Inbox OR maildir:/Junk)
And for the last string-generating code, let’s describe my main inbox:
(mapconcat #'identity
(cons "<<mu4e-bookmarks-default-filter()>>"
`(,(format "(%s)"
<<mu4e-bookmarks-filter-aubay>>)
,(format "(%s)" "<<mu4e-bookmarks-filter-asso()>>")
,(format "(%s)"
<<mu4e-bookmarks-filter-emacs-list>>)
,(format "(%s)"
<<mu4e-bookmarks-filter-github-list>>)
,(format "(%s)"
<<mu4e-bookmarks-filter-uni>>)))
" AND NOT ")NOT flag:trashed AND (maildir:/Inbox OR maildir:/Junk) AND NOT (f:/.*aubay\.com/ OR c:/.*aubay\.com/ OR t:/.*aubay\.com/) AND NOT (f:/.*supran.fr/ OR c:/.*supran.fr/ OR t:/.*supran.fr/) AND NOT (list:/ateliers.*emacs.*/ OR t:/ateliers.*emacs.*/ OR f:/ateliers.*emacs.*/ OR contact:/ateliers.*emacs.*/ OR list:/emacs-.*@gnu.org/ OR t:/emacs-.*@gnu.org/ OR f:/emacs-.*@gnu.org/ OR contact:/emacs-.*@gnu.org/ OR list:/.*eshell-info-banner.*/ OR t:/.*eshell-info-banner.*/ OR f:/.*eshell-info-banner.*/ OR contact:/.*eshell-info-banner.*/ OR list:/.*emacsfr.*/ OR t:/.*emacsfr.*/ OR f:/.*emacsfr.*/ OR contact:/.*emacsfr.*/) AND NOT (list:/.*\.github\.com/ OR t:/.*\.github\.com/ OR f:/.*\.github\.com/ OR contact:/.*\.github\.com/ OR list:/.*\.gitlab\.com/ OR t:/.*\.gitlab\.com/ OR f:/.*\.gitlab\.com/ OR contact:/.*\.gitlab\.com/ OR list:stumpwm-devel@nongnu.org OR t:stumpwm-devel@nongnu.org OR f:stumpwm-devel@nongnu.org OR contact:stumpwm-devel@nongnu.org OR list:/.*sr\.ht/ OR t:/.*sr\.ht/ OR f:/.*sr\.ht/ OR contact:/.*sr\.ht/ AND NOT ( list:/ateliers.*emacs.*/ OR t:/ateliers.*emacs.*/ OR f:/ateliers.*emacs.*/ OR contact:/ateliers.*emacs.*/ OR list:/emacs-.*@gnu.org/ OR t:/emacs-.*@gnu.org/ OR f:/emacs-.*@gnu.org/ OR contact:/emacs-.*@gnu.org/ OR list:/.*eshell-info-banner.*/ OR t:/.*eshell-info-banner.*/ OR f:/.*eshell-info-banner.*/ OR contact:/.*eshell-info-banner.*/ OR list:/.*emacsfr.*/ OR t:/.*emacsfr.*/ OR f:/.*emacsfr.*/ OR contact:/.*emacsfr.*/ )) AND NOT (f:/.*up8\.edu|.*univ-paris8.*/ OR c:/.*up8\.edu|.*univ-paris8.*/ OR t:/.*up8\.edu|.*univ-paris8.*/ OR maildir:/Univ/Inbox OR maildir:/Univ/Junk)
We can finally define our bookmarks! The code reads as follows:
(setq mu4e-bookmarks
`((:name "Inbox"
:key ?i
:query ,(format "%s"
<<mu4e-bookmarks-inbox-filters>>))
(:name "Internship"
:key ?a
:query ,(format "(%s) AND (%s)"
"<<mu4e-bookmarks-default-filter()>>"
<<mu4e-bookmarks-filter-aubay>>))
(:name "University"
:key ?u
:query ,(format "%s AND %s"
"<<mu4e-bookmarks-default-filter()>>"
"<<mu4e-bookmarks-filter-uni()>>"))
(:name "Dev"
:key ?d
:query ,(format "%s AND (%s)"
"<<mu4e-bookmarks-default-filter()>>"
"<<mu4e-bookmarks-filter-github-list()>>"))
(:name "Emacs"
:key ?e
:query ,(format "%s AND %s"
"<<mu4e-bookmarks-default-filter()>>"
<<mu4e-bookmarks-filter-emacs-list>>))
(:name "Supran"
:key ?s
:query ,(format "%s AND %s"
"<<mu4e-bookmarks-default-filter()>>"
"<<mu4e-bookmarks-filter-asso()>>"))
(:name "Sent" :key ?S :query "maildir:/Sent OR maildir:/Univ/Sent")
(:name "All Unread" :key ?U :query "flag:unread AND NOT flag:trashed")
(:name "Today" :key ?t :query "date:today..now AND NOT flag:trashed")
(:name "This Week" :key ?w :query "date:7d..now AND NOT flag:trashed")
(:name "This Month" :key ?m :query "date:1m..now AND NOT flag:trashed")
(:name "This Year" :key ?y :query "date:1y..now AND NOT flag:trashed")))Maildirs
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.
(setq mu4e-maildir-shortcuts
'((:maildir "/Inbox" :key ?i)
(:maildir "/Sent" :key ?s)
(:maildir "/Junk" :key ?j)
(:maildir "/Trash" :key ?t)))Dealing with spammers
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, 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.
(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."))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, 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.
| Mark | Flag | Icon |
|---|---|---|
| draft | D | pencil |
| flagged | F | flag |
| new | N | rss |
| passed | P | check |
| replied | R | reply |
| seen | S | eye |
| unread | u | eye-slash |
| trashed | T | trash |
| attach | a | paperclip |
| encrypted | x | lock |
| signed | s | certificate |
(mapconcat (lambda (line)
(let ((mark (car line))
(flag (cadr line))
(icon (caddr line)))
(format "mu4e-headers-%s-mark `(\"%s\" . ,(all-the-icons-faicon \"%s\" :height 0.8))"
mark
flag
icon)))
table
"\n")mu4e-headers-draft-mark `("D" . ,(all-the-icons-faicon "pencil" :height 0.8))
mu4e-headers-flagged-mark `("F" . ,(all-the-icons-faicon "flag" :height 0.8))
mu4e-headers-new-mark `("N" . ,(all-the-icons-faicon "rss" :height 0.8))
mu4e-headers-passed-mark `("P" . ,(all-the-icons-faicon "check" :height 0.8))
mu4e-headers-replied-mark `("R" . ,(all-the-icons-faicon "reply" :height 0.8))
mu4e-headers-seen-mark `("S" . ,(all-the-icons-faicon "eye" :height 0.8))
mu4e-headers-unread-mark `("u" . ,(all-the-icons-faicon "eye-slash" :height 0.8))
mu4e-headers-trashed-mark `("T" . ,(all-the-icons-faicon "trash" :height 0.8))
mu4e-headers-attach-mark `("a" . ,(all-the-icons-faicon "paperclip" :height 0.8))
mu4e-headers-encrypted-mark `("x" . ,(all-the-icons-faicon "lock" :height 0.8))
mu4e-headers-signed-mark `("s" . ,(all-the-icons-faicon "certificate" :height 0.8))
Let’s enable them and set them:
(setq mu4e-use-fancy-chars t
<<mu4e-fancy-marks-gen()>>)(defun my/set-mu4e-headers-width ()
(let ((width (window-body-width))
(threshold (+ 120 80)))
(setq mu4e-split-view (if (> width threshold)
'vertical
'horizontal))))
(setq mu4e-headers-visible-columns 120
mu4e-headers-visible-lines 15)
(add-hook 'mu4e-headers-mode-hook #'my/set-mu4e-headers-width)Headers mode
(add-hook 'mu4e-headers-mode-hook (lambda () (visual-line-mode -1)))
(add-hook 'mu4e-headers-mode-hook (lambda () (toggle-truncate-lines -1)))Keybindings
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:
(phundrak/undefine
:keymaps 'mu4e-view-mode-map
:packages 'mu4e
"S" nil
"r" nil
"c" nil
"gu" nil)
(phundrak/undefine
:keymaps '(mu4e-view-mode-map mu4e-headers-mode-map)
:packages 'mu4e
"s" nil)
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:
| Keybinding | Function | Description |
|---|---|---|
| & | mu4e-view-pipe | |
| . | mu4e-headers-split-adjust-width/body | mu4e-headers width |

(phundrak/major-leader-key
:keymaps 'mu4e-view-mode-map
:packages 'mu4e
<<general-keybindings-gen(table=mu4e-keybindings-view-tbl)>>)Two other keybinds are added without a prefix, just for the sake of convenience.
(phundrak/evil
:keymaps 'mu4e-view-mode-map
:packages 'mu4e
"«" #'mu4e-view-headers-prev
"»" #'mu4e-view-headers-next)I’ll also declare two keybinds for mu4e’s headers mode.

:keymaps 'mu4e-headers-mode-map
:packages 'mu4e
"t" '(mu4e-view-mark-thread :which-key "mark thread")

I will also redefine without a leader key ctsr in order to be able to
move freely (remember, bépo layout for me).
| Key | Function | Comment |
|---|---|---|
| c | evil-backward-char | |
| t | evil-next-visual-line | |

| Key | Function | Description |
|---|---|---|
| , | message-send-and-exit | |

Email alerts
There is also a package for mu4e which generates desktop notifications when new emails are received. By default, I want to be notified by all messages in my inbox and junk folder. Also, I’ll use Emacs’ default notification system, and I’ll activate the modeline notification.

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:
(defvar emms-source-file-fd (executable-find "fd"))
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!
(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"))))We can finally set this function as our search function.
(setq emms-source-file-directory-tree-function #'emms-source-file-directory-tree-fd)Keybinds
I also want to create a small hydra for manipulating MPD:
(defun shell-command-and-echo (command &optional echo prefix)

pdf-tools enables PDF support for Emacs, much better than its built-in
support with DocView. Aside from the classical settings such as
keybinds, I also enable the midnight colors by default; think of it as
an equivalent of Zathura’s recolor feature which kind of enables a
dark mode for PDFs.

Magit
Magit is an awesome wrapper around Git for Emacs! Very often, I go from disliking to really hating Git GUI clients because they often obfuscate which Git commands are used to make things happen. Such a thing doesn’t happen with Magit, it’s pretty transparent but it still provides some awesome features and visualizations of what you are doing and what Git is doing!

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. Notice my custom function
hooked to magit-mode-hook. This is because this package tries to find
TODOs in all files in the current project, and my yadm repository’s
root is my $HOME. So, yeah, no magit-todos in yadm.
(use-package magit-todos
:straight (:build t)

Finally, it is also possible to use Gitflow’s framework with Magit

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
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 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.

Dired
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.
I used to have an extensive configuration for Dired with a couple of additional packages to make it more usable. Dirvish rendered that obsolete!

However, it is possible to instead use exa when it is available.
Instead of making Emacs’ main thread to the file listing in a
directory, we offload it to an external thread.

:require ("exa")
(when (file-directory-p file)

(add-to-list 'dirvish-preview-dispatchers 'exa)Finally, some directories need to be set for Dired to store various files and images.
(let ((my/file (lambda (path &optional dir)
(expand-file-name path (or dir user-emacs-directory))))
(my/dir (lambda (path &optional dir)

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

(setq eshell-aliases-file (expand-file-name "eshell-alias" user-emacs-directory))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:
(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 " "))
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.
(defalias 'open #'find-file)
(defalias 'openo #'find-file-other-window)
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.
(defalias 'eshell/clear #'eshell/clear-scrollback)
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.
(defalias 'list-buffers 'ibuffer)
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.
(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))))
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.
(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))Autosuggestion
I really like fish’s autosuggestion feature, so let’s reproduce it here!
(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))Commands
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:
(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))
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.
(defun eshell-new ()
"Open a new instance of eshell."
(interactive)
(eshell 'N))
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.
(use-package eshell-z
:defer t
:after eshell
:straight (:build t)
:hook (eshell-mode . (lambda () (require 'eshell-z))))Environment Variables
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.
(setenv "DART_SDK" "/opt/dart-sdk/bin")
(setenv "ANDROID_HOME" (concat (getenv "HOME") "/Android/Sdk/"))
The EDITOR variable also needs to be set for git commands, especially the
yadm commands.
(setenv "EDITOR" "emacsclient -c -a emacs")
Finally, for some specific situations I need SHELL to be set to
something more standard than fish:
(setenv "SHELL" "/bin/sh")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 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.
(use-package eshell-info-banner
:after (eshell)
:defer t
:straight (eshell-info-banner :build t
:type git
:host github
:protocol ssh
:repo "phundrak/eshell-info-banner.el")
:hook (eshell-banner-load . eshell-info-banner-update-banner)
: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.
(use-package eshell-syntax-highlighting
:after (esh-mode eshell)
:defer t
:straight (:build t)
:config
(eshell-syntax-highlighting-global-mode +1))
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.
(use-package powerline-eshell
:if (string= (string-trim (shell-command-to-string "uname -n")) "leon")
:load-path "~/fromGIT/emacs-packages/powerline-eshell.el/"

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.
(use-package tramp
:straight (tramp :type built-in :build t)
:config
<<tramp-add-yadm>>
(csetq tramp-ssh-controlmaster-options nil
tramp-verbose 0
tramp-auto-save-directory (locate-user-emacs-file "tramp/")
tramp-chunksize 2000)
(add-to-list 'backup-directory-alist ; deactivate auto-save with TRAMP
(cons tramp-file-name-regexp nil)))Yadm
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 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:
(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"))))I’ll also create a fuction for connecting to this new Tramp protocol:
(defun my/yadm ()
"Manage my dotfiles through TRAMP."
(interactive)
(magit-status "/yadm::"))EXWM
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.
(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"))
Next is a function I’ve stolen copied from Daviwil’s desktop
configuration. This allows to launch software in the background
easily.
(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)))))
In order to launch Emacs with EXWM with startx, I need a xinit file.
This one is exported to $HOME/.xinitrc.emacs.
xhost +SI:localuser:$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
autorandr -l home
exec emacs --with-exwmEXWM itself
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:
- Kitty
- Qutebrowser
(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)))("kitty" (exwm-workspace-rename-buffer (concat "EXWM: " "Kitty" " - " exwm-title)))
("qutebrowser" (exwm-workspace-rename-buffer (concat "EXWM: " "Qutebrowser" " - " exwm-title)))
(_otherwise (exwm-workspace-rename-buffer exwm-title))
(add-hook 'exwm-update-class-hook
(lambda () (exwm-workspace-rename-buffer exwm-class-name)))
(add-hook 'exwm-update-title-hook
(lambda ()
(pcase exwm-class-name
<<exwm-gen-buffers-rename()>>)))
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.
(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)))
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.
(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)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:
(defconst exwm-workspace-keys '("\"" "«" "»" "(" ")" "@" "+" "-" "/" "*"))With this, we can create keybinds for going or sending X windows to workspaces 0 to 9.
(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))))
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.
(exwm-input-set-key (kbd "s-<return>") (lambda ()
(interactive)
(eshell)))

Bufler
Bufler is a package that organizes and lists buffers in a much better
way than how they are usually sorted. You can easily and quickly find
buffers by their group, not only by their name, and THIS is great
news! Also, no helm please! And for some reasons the keybindings are
borked by default, so let’s redefine them, and let’s also rebind SPC
to p since it would conflict with my main general prefix.

:straight (:build t))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

comfortable than the default ones you get with evil and org naked.

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:
| C |
| emacs-lisp |
| gnuplot |
| latex |
| makefile |
| plantuml |
| python |
| sass |
| shell |
| sql |
'((C . t) (emacs-lisp . t) (gnuplot . t) (latex . t) (makefile . t) (plantuml . t) (python . t) (sass . t) (shell . t) (sql . t))
The corresponding code is as follows:
(org-babel-do-load-languages
'org-babel-load-languages

Some languages can run asynchronously with the help of ob-async.

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

for org files that will be hosted and viewable on Github.

Emphasize text
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 /phundrak/dotfiles/src/commit/724c27724f9b2e00c7aaa6a7bb0b03172f89d7fd/org/config/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.
| Emphasis | Character | Character code |
|---|---|---|
| bold | * |
42 |
| italic | / |
47 |
| underline | _ |
95 |
| verbatim | = |
61 |

126 |

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:
(setq org-use-sub-superscripts (quote {}))ConlangDict
I am currently working on new exporters as well as custom links for my
org websites. They are first thought for my conlanging website, hence
the name, but one can use the package for any org-generated website.
This package provides two exporters, ox-conlang-md and
ox-conlang-json, as well as ol-conlang to handle links to and inside
the dictionary. The markdown files are meant to be used with my custom
Vue front-end (not publicly released yet).
(use-package org-conlang

I manage my blog with Hugo. Although it natively supports the org format, it’s not great compared to its markdown support. So, instead, let’s directly export our org files as markdown files and let Hugo do the rest of the job for us!
(use-package ox-hugo
:defer t

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.

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:
(setq org-latex-compiler "xelatex")
A new backend that was introduced in org-mode for LaTeX source block
coloring is engraved.
(use-package engrave-faces
:defer t
:straight (:build t)
:after org)(require 'engrave-faces)
(csetq org-latex-src-block-backend 'engraved)
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:
clevereffor better references to various elements.svgfor inserting SVG files in PDF outputsbooktabsfor nicer tables- and
tabularxfor tabulars with adjustable columns
(dolist (package '(("AUTO" "inputenc" t ("pdflatex"))
("T1" "fontenc" t ("pdflatex"))
("" "grffile" t)))
(delete package org-latex-default-packages-alist))
(dolist (package '(("capitalize" "cleveref")
("" "booktabs")
("" "tabularx")))
(add-to-list 'org-latex-default-packages-alist package t))
(setq org-latex-reference-command "\\cref{%s}")
By the way, reference links in LaTeX should be written in this format,
since we are using cleveref:
(setq org-export-latex-hyperref-format "\\ref{%s}")Tectonic is awesome for processing LaTeX documents! Look how simple it is!
(setq org-latex-pdf-process
'("tectonic -Z shell-escape --synctex --outdir=%o %f"))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:
(dolist (ext '("bbl" "lot"))
(add-to-list 'org-latex-logfiles-extensions ext t))Reveal.js
(use-package org-re-reveal
:defer t

Yet another exporter I enjoy is 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.
(use-package ox-ssh

:straight (:build t))Keybindings
Be prepared, I have a lot of keybindings for org-mode! They are all

The org-babel-transient hydra allows me to quickly navigate between

one you can find in Spacemacs.

| Key chord | Function | Description |
|---|---|---|
| d | nil | dates |
| dd | org-deadline | |
| ds | org-schedule | |
| dt | org-time-stamp | |
| dT | org-time-stamp-inactive |
Let’s now define some keybinds for inserting stuff in our org buffer:

| i | nil | insert |
| ib | org-insert-structure-template | |
| id | org-insert-drawer | |
| ie | nil | emphasis |

| in | org-add-note | |
| ip | org-set-property | |
| is | org-insert-subheading | |
| it | org-set-tags-command |
There isn’t a lot of stuff I can jump to yet, but there’s still some:
| Key chord | Function | Description |
|---|---|---|
| j | nil | jump |
| ja | counsel-org-goto-all | |
| jh | counsel-org-goto |
Tables get a bit more love:
| Key chord | Function | Description |

LaTeX formats
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:
'("conlang"
"\\documentclass{book}"
("\\chapter{%s}" . "\\chapter*{%s}")
("\\section{%s}" . "\\section*{%s}")
("\\subsection{%s}" . "\\subsection*{%s}")
("\\subsubsection{%s}" . "\\subsubsection*{%s}"))
And here is the declaration of the beamer class:
`("beamer"
,(concat "\\documentclass[presentation]{beamer}\n"
"[DEFAULT-PACKAGES]"
"[PACKAGES]"
"[EXTRA]\n")
("\\section{%s}" . "\\section*{%s}")
("\\subsection{%s}" . "\\subsection*{%s}")
("\\subsubsection{%s}" . "\\subsubsection*{%s}"))
Both these classes have to be added to org-latex-classes like so:
(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>>)))Projects
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:
<<org-proj-config-setup>>
<<org-proj-lang-setup>>
(setq org-publish-project-alist
`(
<<org-proj-config-html>>
<<org-proj-config-static>>
<<org-proj-config>>
<<org-proj-lang-html>>
<<org-proj-lang-pdf>>
<<org-proj-lang-static>>
<<org-proj-lang>>))Configuration website
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.
(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.")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.
("config-website-html"
:base-directory ,phundrak//projects-config-source
:base-extension "org"

("config-website"
:components ("config-website-org"
"config-website-static"))Conlanging website
Conlangs, or constructed languages, are artificial languages created by individuals or by groups of individuals, unlike natural languages which evolve and appear naturally from other languages.
My conlanging website is made out of three projects. As for the previous project, let’s declare the common values for these.
(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.")The first component is the one generating the HTML files from the org files.
("conlang-phundrak-com-html"
:base-directory ,phundrak//projects-conlanging-source
:base-extension "org"
:exclude ,(rx (* print)
(or "CONTRIB"

:publishing-function org-latex-publish-to-pdf
:headline-levels 5
:auto-preamble t)And lastly, we have the component for all the static files needed to run the website:
("conlang-phundrak-com-static"
:base-directory ,phundrak//projects-conlanging-source
:base-extension "png\\|jpg\\|gif\\|webp\\|svg\\|jpeg\\|ttf\\|woff\\|txt\\|epub"

("conlang-phundrak-com"
:components ("conlang-phundrak-com-org"

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!
(use-package mixed-pitch

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!

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:

CMake is one of the standard tools for indicating how a project should 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.

It is not rare to encounter a dotenv file, that is, a file with either
the .env extension or simply called .env. They contain environment
variables for projects which might rely on values you do not want to
upload to a public git repository and such. While their syntax is
similar to shell files, they’re not exactly shell files either since
there’s rarely any script inside running. So, let’s install a simple
package which will dumb down a lot sh-mode for these dotenv files.

C/C++
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
CommonLisp. stumpwm-mode offers some integration between Emacs and
StumpWM so we can evaluate CLisp code and see its effects in StumpWM

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.

You may have noticed I use the Nord theme pretty much everywhere on my computer, why not Emacs? In my opinion, its aurora variant is nicer than the default Nord theme since it is richer in colors — just a personal preference.
(use-package doom-themes
:straight (:build t)

This makes Lisp especially more readable, but it’s also nice to have for any language that has delimiters like brackets too.
(use-package rainbow-delimiters

It is possible to make info buffers much more colorful (and imo easier to read) with this simple package:

ArchWiki pages
A small package I’ve written allows the user to view ArchLinux pages either in Emacs or in an external web browser. I prefer the defaults.

avy is a really convenient way of jumping around and performing
actions on these selections, but I’ll need some configuration to make
it bépo-compatible.
