** 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
[[https://github.com/bitwarden/cli][Bitwarden CLI]]. Use at your own risks.

** Calendar
I am using the built-in calendar of Emacs, but as I use Evil and the
bépo layout, many keybindings available by default or through
=evil-collection= don’t fit my needs perfectly.

** Docker
Docker is an awesome tool for reproducible development environments.
Due to this, I absolutely need a mode for editing Dockerfiles.
#+begin_src emacs-lisp
(use-package dockerfile-mode
:defer t
:straight (:build t)
:hook (dockerfile-mode . lsp-deferred)
:init
(put 'docker-image-name 'safe-local-variable #'stringp)
:mode "Dockerfile\\'"
:general
(phundrak/major-leader-key
:keymaps 'general-mode-map
:packages 'lsp-mode
"l" '(:keymap lsp-command-map :which-key "lsp")))
#+end_src
The ~docker~ package also provides interactivity with Docker and
docker-compose from Emacs.
#+begin_src emacs-lisp
(use-package docker
:defer t
:straight (:build t))
#+end_src
** Elfeed
Elfeed is a nice Atom and RSS reader for Emacs. The only thing I want
to change for now is the default search filter: I want to see not only
unread news but read news as well, a bit like my emails; and where the
database is to be stored.
#+begin_src emacs-lisp
(use-package elfeed
:defer t
:straight (:build t)
:config
<<elfeed-open-youtube-with-mpv>>
:custom
((elfeed-search-filter "@6-months-ago")
(elfeed-db-directory (expand-file-name ".elfeed-db"
user-emacs-directory))))
#+end_src
I don’t want YouTube videos to be open with my web browser when I
invoke ~elfeed-show-visit~, so I’ll advise this function to make it
possible to modify the behavior of said function. Oh, and I already
made [[file:../../scripts.md#ytplay][a neat package]] for playing YouTube videos and friends through
[[https://ytdl-org.github.io/youtube-dl/][youtube-dl]] or its superior fork [[https://github.com/yt-dlp/yt-dlp][yt-dlp]] in mpv.
#+name: elfeed-open-youtube-with-mpv
#+begin_src emacs-lisp
(defun my/elfeed-filter-youtube-videos (orig-fun &rest args)
"Open with mpv the video leading to PATH"
(let ((link (elfeed-entry-link elfeed-show-entry)))
(when link
(if (string-match-p ".*youtube\.com.*watch.*" link)
;; This is a YouTube video, open it with mpv
(progn
(require 'ytplay)
(ytplay link))
(apply orig-fun args)))))
(advice-add 'elfeed-show-visit :around #'my/elfeed-filter-youtube-videos)
#+end_src
A future improvement to be made is to let the user chose the
resolution of the video before it is launched. I may not always have
the best internet connection, and viewing 4K videos on a 1080p display
is not something very useful.
Elfeed-goodies is a package which enhances the Elfeed experience.
Aside from running its setup command as soon as possible, I also set
in this code block all my keybinds for Elfeed here.
#+begin_src emacs-lisp
(use-package elfeed-goodies
:defer t

#+end_src
Last but not least, my Elfeed configuration is stored in an org file
thanks to ~elfeed-org~.
#+begin_src emacs-lisp

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

I have some additional keybinds for ~elfeed-search-mode~, but these one
are prefixed with ~,~ (and ~M-m~).

** Email
*** Basic configuration
As seen below, I use ~org-msg~ to compose my emails, which includes by
default my signature. Therefore, there is no need for Emacs itself to
know about it since I don’t want it to include it a second time after
~org-msg~ already did.

*** Mu4e
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
configuration for the ~mu4e~ package itself.

#+end_src
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
to make it possible to open mu4e directly from my program picker. It
uses the shell script ~emacsmail~ I’ve written [[file:bin.org::#Emacsmail-afffb7cd][here]].

**** Interact with iCalendar events
Something that has always bugged me was how to properly with iCalendar
events shared with me on my personal mailbox. The answer is actually
[[https://www.djcbsoftware.nl/code/mu/mu4e/iCalendar.html][dead simple]].
#+name: mu4e-ical-setup
#+begin_src emacs-lisp
(require 'mu4e-icalendar)
(mu4e-icalendar-setup)
#+end_src
I’ll just configure a couple of things regarding these events, namely
converting them to Orgmode and add them to my =~/org/notes.org= file,
and delete the email once I answered to the event.
#+name: mu4e-ical-config
#+begin_src emacs-lisp
(setq mu4e-icalendar-trash-after-reply t)
#+end_src
#+name: mu4e-ical-init-config
#+begin_src emacs-lisp
(setq gnus-icalendar-org-capture-file "~/org/notes.org"
gnus-icalendar-org-capture-headline '("Calendar"))
(gnus-icalendar-org-setup)
#+end_src
**** Basic configuration
First, let’s inform Emacs how it can send emails, using which service
and how. In my case, I use my own mail server.
#+name: mu4e-mail-service
#+begin_src emacs-lisp :tangle no
(setq smtpmail-smtp-server "mail.phundrak.com"
smtpmail-smtp-service 587
smtpmail-stream-type 'starttls
message-send-mail-function 'smtpmail-send-it)
#+end_src
We also need to inform it on where my emails are stored on my machine,
and how to retrieve them.
#+name: mu4e-mail-on-machine
#+begin_src emacs-lisp :tangle no
(setq mu4e-get-mail-command "mbsync -a"
mu4e-root-maildir "~/Mail"
mu4e-trash-folder "/Trash"
mu4e-refile-folder "/Archive"
mu4e-sent-folder "/Sent"
mu4e-drafts-folder "/Drafts")
#+end_src
In the same vein of [[*Basic configuration][this bit of configuration]], I do not want mu4e to
insert my mail signature, ~org-msg~ already does that.
#+name: mu4e-no-signature
#+begin_src emacs-lisp :tangle no
(setq mu4e-compose-signature nil)
#+end_src
**** 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 [[https://emacs-doctor.com/lists/listinfo][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).
#+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

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:

When it comes to my internship, all emails will contain an address containing ~aubay.com~ (that’s where my internship takes place).
- ~/.*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:

(setq mu4e-bookmarks
`((:name "Inbox"

**** 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.
#+name: mu4e-maildirs
#+begin_src emacs-lisp :tangle no
(setq mu4e-maildir-shortcuts

**** 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, [[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 to avoid me going 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~.
#+name: mu4e-fancy-marks-tbl
| Mark | Flag | Icon |
|-----------+------+-------------|

| encrypted | x | lock |
| signed | s | certificate |
#+name: mu4e-fancy-marks-gen
#+header: :tangle no :exports none :results value :cache yes
#+begin_src emacs-lisp :var table=mu4e-fancy-marks-tbl
(mapconcat (lambda (line)
(let ((mark (car line))

(icon (caddr line)))
(format "mu4e-headers-%s-mark `(\"%s\" . ,(all-the-icons-faicon \"%s\" :height 0.8))"
mark

icon)))
table
"\n")
#+end_src

mu4e-headers-signed-mark `("s" . ,(all-the-icons-faicon "certificate" :height 0.8))
#+end_example
Let’s enable them and set them:
#+name: mu4e-fancy-marks
#+begin_src emacs-lisp :tangle no
(setq mu4e-use-fancy-chars t
<<mu4e-fancy-marks-gen()>>)
#+end_src

(setq mu4e-headers-visible-columns 120
mu4e-headers-visible-lines 15)

#+end_src
**** 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:
#+name: mu4e-keybindings-undef
#+begin_src emacs-lisp :tangle no
(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)
#+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
| Keybinding | Function | Description |
|------------+--------------------------------------+--------------------|
| & | mu4e-view-pipe | |
| . | mu4e-headers-split-adjust-width/body | mu4e-headers width |

| u | nil | url |

#+name: mu4e-keybindings-view

:keymaps 'mu4e-view-mode-map
:packages 'mu4e

#+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
:keymaps 'mu4e-view-mode-map
:packages 'mu4e

"»" #'mu4e-view-headers-next)
#+end_src
I’ll also declare two keybinds for mu4e’s headers mode.
#+name: mu4e-keybindings-header
#+begin_src emacs-lisp :tangle no

: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-table
| Key | Function | Comment |
|-----+---------------------------+---------|
| c | evil-backward-char | |

:keymaps 'mu4e-headers-mode-map
:packages 'mu4e
<<general-keybindings-gen(table=mu4e-keybindings-header-no-leader-table)>>)
#+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 |
|-----+-----------------------+-------------|
| , | message-send-and-exit | |

#+end_src
*** Composing messages
Org mime is cool and all, you can write some org-mode and then export
it to either a plain-text or an HTML email. BUT, have you considered
skipping the export part and write your emails directly in org-mode?
#+begin_src emacs-lisp

:general

*** 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.
#+begin_src emacs-lisp

** EMMS and Media
EMMS, also known as the /Emacs MultiMedia System/, allows the user to

*** Finding files from EMMS
:PROPERTIES:
:header-args:emacs-lisp: :tangle no
:END:
EMMS has two default ways of finding files: either a built-in function
relatively slow but portable, or with ~find~ which is arguably faster
but less portable. Honestly, I don’t care about portability, I’ll
always use this Emacs config on Linux, but I don’t want to use ~find~
either since there is something even faster: ~fd~.
First we’ll declare a variable that can hold the path to the ~fd~
executable:
#+name: emms-fd-name
#+begin_src emacs-lisp
(defvar emms-source-file-fd (executable-find "fd"))
#+end_src
Then, we need to declare a new function that will use ~fd~ to find
files. The function, as specified by the documentation of
~emms-source-file-directory-tree-function~, receives two arguments ~dir~
and ~regex~. We can work with that!
#+name: emms-fd-function
#+begin_src emacs-lisp
(defun emms-source-file-directory-tree-fd (dir regex)
"Return a list of all files under DIR that match REGEX.
This function uses the external fd utility. The name for fd may
be supplied using `emms-source-file-fd'."
(with-temp-buffer
(call-process emms-source-file-fd
nil t nil
"-L" ; follow symlinks
regex
"-t f"
(expand-file-name dir))
(delete ""
(split-string (buffer-substring (point-min)
(point-max))
"\n"))))
#+end_src
We can finally set this function as our search function.
#+name: emms-search-set-variable
#+begin_src emacs-lisp
(setq emms-source-file-directory-tree-function #'emms-source-file-directory-tree-fd)
#+end_src
*** Keybinds

** Nov
Nov is a major-mode for reading EPUB files within Emacs. Since I have
it, I don’t need any other Epub reader on my computer! Plus this one
is customizable and programmable, why would I use any other EPUB
reader?

** PDF Tools
~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.

** Project Management
*** 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! In short, I absolutely love it!

There is currently a bug in Emacs TRAMP as described in issue [[https://github.com/magit/magit/issues/4720][#4720]] of
Magit and bug [[https://debbugs.gnu.org/cgi/bugreport.cgi?bug=62093][62093]] of Emacs. A workaround is to redefine the old
=tramp-send-command= function through an advice.
#+begin_src emacs-lisp
(defun my--tramp-send-command--workaround-stty-icanon-bug (conn-vec orig-command &rest args)
"See: https://github.com/magit/magit/issues/4720"
(let ((command
(if (string= "stty -icrnl -icanon min 1 time 0" orig-command)
"stty -icrnl"
orig-command)))
(append (list conn-vec command) args)))
(defun my--tramp-send-command--workaround-stty-icanon-bug--filter-args (args)
(apply #'my--tramp-send-command--workaround-stty-icanon-bug args))
(advice-add 'tramp-send-command :filter-args
#'my--tramp-send-command--workaround-stty-icanon-bug--filter-args)
#+end_src
[[https://github.com/alphapapa][Alphapapa]] also created an awesome package for Magit: magit-todos which
display in the Magit buffer a list of TODOs found in the current
project to remind you of what to do next.
First, let’s se tup 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.
#+begin_src emacs-lisp
(use-package hl-todo
:defer t
:straight (:build t)
:init (global-hl-todo-mode 1)
:general
(phundrak/leader-key
:packages '(hl-todo)
:infix "c"
"" '(:ignore t :which-key "todos")
"n" #'hl-todo-next
"p" #'hl-todo-previous))
#+end_src
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.
#+begin_src emacs-lisp
(use-package magit-todos
:straight (:build t)
:after (magit hl-todo)
:init
(with-eval-after-load 'magit
(defun my/magit-todos-if-not-yadm ()
"Deactivate magit-todos if in yadm Tramp connection.
If `magit--default-directory' points to a yadm Tramp directory,
deactivate `magit-todos-mode', otherwise enable it."
(if (string-prefix-p "/yadm:" magit--default-directory)
(magit-todos-mode -1)
(magit-todos-mode +1)))
(add-hook 'magit-mode-hook #'my/magit-todos-if-not-yadm))
:config
(csetq magit-todos-ignore-case t))
#+end_src
Finally, =git-cliff= generates changelogs within Magit itself using [[https://github.com/orhun/git-cliff][=git-cliff=]].
#+begin_src emacs-lisp
(use-package git-cliff
:straight (:build t :type git :host github :repo "liuyinz/git-cliff.el")

*** Forge
Forge acts as an interface for GitHub, Gitlab, and Bitbucket inside
Magit. A lot of possibilities are present, you can read issues and
pull requests, create them, and fork projects among other things.
*NOTE*: Make sure to configure a GitHub token before using this
package!

*** Projectile
First, I need to install ~ripgrep~, a faster reimplementation of ~grep~,
which will be very useful when managing projects.
#+begin_src emacs-lisp

:straight (:build t)
:defer t)
#+end_src
Now, I can use projectile, which is sort of the /de facto/ standard
project manager in Emacs. I know there’s ~project.el~, but… Eh… I’m used
to projectile.
#+begin_src emacs-lisp
(use-package projectile
:straight (:build t)

#+end_src
And of course, there is a counsel package dedicated to projectile.

*** Recentf
The built-in package ~recentf~ keeps track of recently opened files. But
by default, it only follows the twenty most recent files, that not
nearly enough for me, so I raise it to two hundred. I also don’t want
recentf to follow the Elfeed database, so I add it to the list of
excluded files.
#+begin_src emacs-lisp

*** VTerm
VTerm gives Emacs access to regular shells with an almost regular
emulator. Be aware you will most likely need to hit ~C-c~ twice to send
an interrupt signal.
#+begin_src emacs-lisp

:defer t

One annoying think with vterm is it only can create one buffer, you
can’t have multiple vterm buffers by default. ~multi-vterm~ fixes this
issue.
#+begin_src emacs-lisp

** XWidgets Webkit Browser
I used to use the xwidgets webkit browser in order to view or preview
HTML files from Emacs, but it seems the Cairo background transparency
patch breaks it. So while this isn’t patched, I will disable Xwidgets
