* Introduction
#+begin_center
*STOP* Read this first!
You just landed on my vanilla Emacs configuration. However, this URL
was used until recently for my Spacemacs configuration. If you want my
complete, working Emacs configuration, I recommend you to head over
there. /*This document is still a work in progress!*/
#+end_center
After a couple of years using Spacemacs and a failed attempt at
switching to DoomEmacs, I’m finally switching back to a vanilla
configuration! Be aware though this document is still very much a work
in progress document, lots of comments on existing configuration are
missing, and lots of functionnalities are still not implemented. I’m
still in the process of porting my [[file:spacemacs.org][Spacemacs]] configuration over here.

** Early init
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.
#+begin_src emacs-lisp :mkdirp yes :tangle ~/.emacs.vanilla/early-init.el :exports code :results silent :lexical t
(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
#+end_src
** Personal 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.
#+begin_src emacs-lisp
(setq user-full-name "Lucien Cartier-Tilet"
user-real-login-name "Lucien Cartier-Tilet"
user-login-name "phundrak"
user-mail-address "lucien@phundrak.com")
#+end_src
** 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 acces.
#+begin_src emacs-lisp
(setq backup-directory-alist `(("." . ,(expand-file-name ".temp/backups/" user-emacs-directory))))
#+end_src
It also loves to litter its ~init.el~ with custom variables here and
there, but the thing is: I regenerate my ~init.el~ each time I tangle
this file! How can I keep Emacs from adding stuff that will be almost
immediately lost? Did someone say /custom file/?
#+begin_src emacs-lisp
(setq-default custom-file (expand-file-name ".custom.el" user-emacs-directory))
(when (file-exists-p custom-file) ; Don’t forget to load it, we still need it
(load custom-file))
#+end_src
Finally, the scatch buffer always has some message at its beginning, I
don’t want it!
#+begin_src emacs-lisp
(setq-default initial-scratch-message nil)
#+end_src
** Editing text in Emacs
I don’t like tabs. They rarely look good, and if I need it I can
almost always tell Emacs to use them through a ~.dir-locals.el~ file or
through the config file of my code formatter. So by default, let’s
disable them:
#+begin_src emacs-lisp
(setq-default indent-tabs-mode nil)
(add-hook 'prog-mode-hook (lambda () (setq indent-tabs-mode nil)))
#+end_src
Just to go on a little tangeant here: I don’t exactly /hate/ tabs, but I
find them really annoying when your text editor knows only them. Sure,
for indentation they work great and they allow different people
getting different settings in their text editor depending on their
preferred tastes —some may prefer 2 spaces tabs, some may prefer 4
spaces tabs, some deranged people prefer 8 spaces tabs, and some
monsters prefer 3!
But the thing is, once you indented your code and then you need
alignment, tabs don’t work anymore! Or they may on *your* text editor
but not on your coworker’s! (He’s the one using 3 spaces tabs by the
way).
So, is the answer to use spaces instead of tabs, and screw peoples’
preferences in terms of tabs width? No, I say the answer is more
moderate than that, and it might frighten or anger some of you at
first: use both spaces and tabs. Now, before you lynch me on the main
avenue in front of everyone, let me tell you absolutely no one should
ever be mixing spaces and tabs for indentation, that would be
absolutely terrible and would bring the worst of both worlds. What’s
the best of both worlds then?
#+begin_center
/Tabs for indentation/
/Spaces for alignment/
#+end_center
I haven’t found a way to automate that in Emacs yet aside from
formatters’ config file, and tabs look bat in EmacsLisp anyways, so
I’ll stick with spaces by default and change it where needed.
I *never* want to keep trailing spaces in my files, which is why I’m
doing this:
#+begin_src emacs-lisp
(add-hook 'before-save-hook #'whitespace-cleanup)
#+end_src
** Fonts
I don’t like the default font I usually have on my machines, I really don’t.
#+begin_src emacs-lisp
(defvar phundrak/default-font-size 90
"Default font size.")
#+end_src
#+begin_src emacs-lisp
(when (equal system-type 'gnu/linux)
(set-face-attribute 'default nil :font "Cascadia Code" :height phundrak/default-font-size))
#+end_src
** Nice macros from Doom-Emacs
Doom-Emacs has some really nice macros that can come in really handy,
but since I prefer to rely on my own configuration, I’ll instead just
copy their code here. First we get the ~after!~ macro:
#+begin_src emacs-lisp
(defmacro after! (package &rest body)
"Evaluate BODY after PACKAGE have loaded.
PACKAGE is a symbol or list of them. These are package names, not modes,
functions or variables. It can be:
- An unquoted package symbol (the name of a package)
(after! helm BODY...)
- An unquoted list of package symbols (i.e. BODY is evaluated once both magit
and git-gutter have loaded)
(after! (magit git-gutter) BODY...)
- An unquoted, nested list of compound package lists, using any combination of
:or/:any and :and/:all
(after! (:or package-a package-b ...) BODY...)
(after! (:and package-a package-b ...) BODY...)
(after! (:and package-a (:or package-b package-c) ...) BODY...)
Without :or/:any/:and/:all, :and/:all are implied.
This is a wrapper around `eval-after-load' that:
1. Suppresses warnings for disabled packages at compile-time
2. Supports compound package statements (see below)
3. Prevents eager expansion pulling in autoloaded macros all at once"
(declare (indent defun) (debug t))
(if (symbolp package)
(list (if (or (not (bound-and-true-p byte-compile-current-file))
(require package nil 'noerror))
#'progn
#'with-no-warnings)
;; We intentionally avoid `with-eval-after-load' to prevent eager
;; macro expansion from pulling (or failing to pull) in autoloaded
;; macros/packages.
`(eval-after-load ',package ',(macroexp-progn body)))
(let ((p (car package)))
(cond ((not (keywordp p))
`(after! (:and ,@package) ,@body))
((memq p '(:or :any))
(macroexp-progn
(cl-loop for next in (cdr package)
collect `(after! ,next ,@body))))

* 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 /Elpa/ repository has been renamed to
the /gnu/ repository due to the addition of another Elpa repository,
/nongnu/, which will hosts packages that do not conform to the FSF’s
copyright assignment. Both the /gnu/ and the /nonfree/ repositories are
Elpa repositories now, and they were renamed in order to avoid any
confusion between the two of them.
#+begin_src emacs-lisp
(setq package-archives '(("melpa" . "https://melpa.org/packages/")
("org" . "https://orgmode.org/elpa/")
("gnu" . "https://elpa.gnu.org/packages/")
("nongnu" . "https://elpa.nongnu.org/nongnu/")))
#+end_src
** Straight
For my package management, I prefer to use ~straight~ ([[https://github.com/raxod502/straight.el][Github]]). This is
due to its capacity of integrating nicely with ~use-package~, which is
also supported by ~general~ which I use for my keybindings (see below),
but also because with it I can specify where to retrieve packages that
are not on MELPA or ELPA but on Github and other online Git
repositories too.
#+begin_src emacs-lisp
(defvar bootstrap-version)

The following hydra allows me to quickly zoom in and out in the

This one allows me to quickly navigate between code blocks and

in Spacemacs.

*** Ivy
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~.

*** Eshell
Eshell is a built-in shell available from Emacs which I use almost as
often as fish. Some adjustments are necessary to make it fit my taste
though.
#+begin_src emacs-lisp
(general-define-key
:keymaps 'eshell-mode-map
:states 'insert
"C-a" #'eshell-bol
"C-e" #'end-of-line)
#+end_src
**** Aliases
First, let’s declare our list of “dumb” aliases we’ll use in
Eshell. You can find them here.
#+begin_src emacs-lisp
(setq eshell-aliases-file (expand-file-name "eshell-aliases" user-emacs-directory))
#+end_src
A couple of other aliases will be defined through custom Elisp
functions, but first I’ll need a function for concatenating a shell
command into a single string:
#+begin_src emacs-lisp
(defun phundrak/concatenate-shell-command (&rest command)
"Concatenate an eshell `COMMAND' into a single string.
All elements of `COMMAND' will be joined in a single
space-separated string."
(string-join command " "))
#+end_src
I’ll also declare some aliases here, such as ~open~ and ~openo~ that
respectively allow me to open a file in Emacs, and same but in another
window.
#+begin_src emacs-lisp
(defalias 'open 'find-file)
(defalias 'openo 'find-file-other-window)
#+end_src
As you see, these were not declared in my dedicated aliases file but
rather were declared programmatically. This is because I like to keep
my aliases file for stuff that could work too with other shells were
the syntax a bit different, and aliases related to Elisp are kept
programmatically. I’ll also declare ~list-buffers~ an alias of ~ibuffer~
because naming it that way kind of makes more sense to me.
#+begin_src emacs-lisp
(defalias 'list-buffers 'ibuffer)
#+end_src
I still have some stupid muscle memory telling me to open ~emacs~, ~vim~
or ~nano~ in Eshell, which is stupid: I’m already inside Emacs and I
have all its power available instantly. So, let’s open each file
passed to these commands.
#+begin_src emacs-lisp
(defun eshell/emacs (&rest file)
"Open each `FILE' and kill eshell.
Old habits die hard."
(when file
(dolist (f (reverse file))
(find-file f t))))
#+end_src
Finally, I’ll declare ~mkcd~ which allows the simultaneous creation of a
directory and moving into this newly created directory. And of course,
it will also work if the directory also exists or if parent
directories don’t, similarly to the ~-p~ option passed to ~mkdir~.
#+begin_src emacs-lisp
(defun eshell/mkcd (dir)
"Create the directory `DIR' and move there.
If the directory `DIR' doesn’t exist, create it and its parents
if needed, then move there."
(mkdir dir t)
(cd dir))
#+end_src
**** Custom Functions
When I’m in Eshell, sometimes I wish to open multiple files at once in
Emacs. For this, when I have several arguments for ~find-file~, I want
to be able to open them all at once. Let’s modify ~find-file~ like so:
#+BEGIN_SRC emacs-lisp
(defadvice find-file (around find-files activate)
"Also find all files within a list of files. This even works recursively."
(if (listp filename)
(cl-loop for f in filename do (find-file f wildcards))

I also want to be able to have multiple instances of Eshell opened at
once. For that, I declared the function ~eshell-new~ that does exactly
that.
#+begin_src emacs-lisp
(defun eshell-new ()
"Open a new instance of eshell."
(interactive)
(eshell 'N))
#+end_src
**** Environment Variables
Some environment variables need to be correctly set so Eshell can correctly
work. The first environment variable to be set is the ~PATH~, as I have a couple
of directories where executables are located. Let’s add them to our
path if they aren’t already.
#+name: table-eshell-env-path
#+caption: Paths to add to ~PATH~
| Path | Relative to ~HOME~? |
|---------------------+-------------------|
| .pub-cache/bin | yes |
| .local/bin | yes |
| .cargo/bin | yes |
| .gen/ruby/2.6.0/bin | yes |
| go/bin | yes |
#+name: src-eshell-env-path
#+begin_src emacs-lisp :exports none :tangle no :var paths=table-eshell-env-path :noweb yes
(progn
(setq-local PATH (getenv "PATH"))
(dolist (path paths)
(let ((path (if (equal "yes" (cadr path))
(concat (getenv "HOME")
"/"
(car path))
(car path))))
(unless (string-match-p (regexp-quote path) PATH)
(setq-local PATH (concat path ":" PATH)))))
PATH)
#+end_src
#+begin_src emacs-lisp
(setenv "PATH" "<<src-eshell-env-path()>>")
#+end_src
I would also like to set two environment variables related to Dart development:
the ~DART_SDK~ and ~ANDROID_HOME~ variables.
#+BEGIN_SRC emacs-lisp
(setenv "DART_SDK" "/opt/dart-sdk/bin")
(setenv "ANDROID_HOME" (concat (getenv "HOME") "/Android/Sdk/"))
#+END_SRC
The ~EDITOR~ variable also needs to be set for git commands, especially the
~yadm~ commands.
#+BEGIN_SRC emacs-lisp
(setenv "EDITOR" "emacsclient -c")
#+END_SRC
Finally, for some specific situations I need ~SHELL~ to be set to
something more standard than fish:
#+begin_src emacs-lisp
(setenv "SHELL" "/bin/sh")
#+end_src
**** Visual configuration
I like to have at quick glance some information about my machine when
I fire up a terminal. I haven’t found anything that does that the way
I like it, so [[https://github.com/Phundrak/eshell-info-banner.el][I’ve written a package]]!
#+begin_src emacs-lisp

Since very recently, the ~contrib/lisp/~ directory of org moved out of
the main repository to [[https://git.sr.ht/~bzg/org-contrib][this repository]]. On the other hand,
~contrib/scripts/~ moved to [[https://code.orgmode.org/bzg/worg/src/master/code][the worg repository]], but I don’t need
it. The main reason I want ~org-contrib~ is due to ~ox-extra~ that allow
the usage of the ~:ignore:~ tag in org.
#+begin_src emacs-lisp
(use-package org-contrib
:straight (:build t)
:init
(require 'ox-extra)
(ox-extras-activate '(latex-header-blocks ignore-headlines)))
#+end_src
**** Agenda
:PROPERTIES:
:header-args:emacs-lisp: :tangle no :exports code :results silent
:END:
#+name: org-agenda-files
#+begin_src emacs-lisp
(setq-default org-agenda-files (list "~/org/agenda" "~/org/notes.org"))
#+end_src
**** Behavior
A useful package I like is ~toc-org~ which creates automatically a table
of contents. My main usage for this however is not just to create a
table of content of my files to quickly jump around my file (I have
~counsel-org-goto~ for that), but it is for creating table of contents
for org files that will be hosted and viewable on Github.
#+begin_src emacs-lisp
(use-package toc-org
:after org
:straight (:build t)
:init
(add-to-list 'org-tag-alist '("TOC" . ?T))
:hook (org-mode . toc-org-mode)
:hook (markdown-mode . toc-org-mode))
#+end_src
**** Babel
A package I use from time to time is ~ob-latex-as-png~ which allows me
to easily convert a LaTeX snippet into a PNG, regardless of the
exporter I use afterwards. Its installation is pretty simple:
#+begin_src emacs-lisp
(use-package ob-latex-as-png
:defer t
:straight (:build t))
#+end_src
**** File export
:PROPERTIES:
:header-args:emacs-lisp: :tangle no :exports code :results silent
:END:
I want to disable by default behavior of ~^~ and ~_~ for only one
character, making it compulsory to use instead ~^{}~ and ~_{}~
respectively. This is due to my frequent usage of the underscore in my
org files as a regular character and not a markup one, especially when
describing phonetics evolution. So, let’s disable it:
#+NAME: org-use-sub-superscripts
#+BEGIN_SRC emacs-lisp
(setq org-use-sub-superscripts (quote {}))
#+END_SRC
***** LaTeX
When it comes to exports, I want the LaTeX and PDF exports to be done
with XeLaTeX only. This implies the modification of the following
variable:
#+NAME: org-latex-compiler
#+BEGIN_SRC emacs-lisp
(setq org-latex-compiler "xelatex")
#+END_SRC
I also want to get by default ~minted~ for LaTeX listings so I can have
syntax highlights:
#+NAME: org-latex-listings
#+BEGIN_SRC emacs-lisp
(setq org-latex-listings 'minted)
#+END_SRC
The default packages break my LaTeX exports: for some reasons, images
are not loaded and exported in PDFs, so I needed to redifine the
default packages excluding the one that broke my exports. I also added
a default package, ~minted~ for syntax highlighting.
#+NAME: org-latex-default-packages
#+BEGIN_SRC emacs-lisp
(setq org-latex-default-packages-alist '(("" "graphicx" t)
("T1" "fontspec" t ("pdflatex"))
("" "longtable" nil)
("" "wrapfig" nil)
("" "rotating" nil)
("normalem" "ulem" t)
("" "amsmath" t)
("" "textcomp" t)
("" "amssymb" t)
("" "capt-of" nil)
("" "minted" nil)
("" "hyperref" nil)))
#+END_SRC
By the way, reference links in LaTeX should be written in this format:
#+NAME: org-export-latex-hyperref-format
#+BEGIN_SRC emacs-lisp
(setq org-export-latex-hyperref-format "\\ref{%s}")
#+END_SRC
When it comes to the export itself, the latex file needs to be
processed several times through XeLaTeX in order to get some
references right. Don’t forget to also run bibtex!
#+NAME: org-latex-pdf-process
#+BEGIN_SRC emacs-lisp
(setq org-latex-pdf-process
'("xelatex -8bit -shell-escape -interaction nonstopmode -output-directory %o %f"
"bibtex %b"
"xelatex -8bit -shell-escape -interaction nonstopmode -output-directory %o %f"
"xelatex -8bit -shell-escape -interaction nonstopmode -output-directory %o %f"))
#+END_SRC
Finally, org-mode is supposed to automatically clean logfiles after it
exports an org file to LaTeX. However, it misses a few, so I need to
add their extension like so:
#+begin_src emacs-lisp
(dolist (ext '("bbl" "lot"))
(add-to-list 'org-latex-logfiles-extensions ext t))
#+end_src
***** HTML
For Reveal.JS exports, I need to set where to find the framework by
default:
#+NAME: org-re-reveal-root
#+BEGIN_SRC emacs-lisp
(setq org-re-reveal-root "https://cdn.jsdelivr.net/npm/reveal.js")
#+END_SRC
On HTML exports, Org-mode tries to include a validation link for the
exported HTML. Let’s disable that since I never use it.
#+NAME: org-html-validation
#+BEGIN_SRC emacs-lisp
(setq org-html-validation-link nil)
#+END_SRC
**** LaTeX formats
:PROPERTIES:
:header-args:emacs-lisp: :tangle no :exports code :results silent
:END:
I currently have two custom formats for my Org-mode exports: one for general use
(initialy for my conlanging files, hence its ~conlang~ name), and one for beamer
exports.
Below is the declaration of the ~conlang~ LaTeX class:
#+NAME: org-latex-class-conlang
#+BEGIN_SRC emacs-lisp
'("conlang"
"\\documentclass{book}"
("\\chapter{%s}" . "\\chapter*{%s}")
("\\section{%s}" . "\\section*{%s}")
("\\subsection{%s}" . "\\subsection*{%s}")
("\\subsubsection{%s}" . "\\subsubsection*{%s}"))
#+END_SRC
And here is the declaration of the ~beamer~ class:
#+NAME: org-latex-class-beamer
#+BEGIN_SRC emacs-lisp
`("beamer"
,(concat "\\documentclass[presentation]{beamer}\n"
"[DEFAULT-PACKAGES]"
"[PACKAGES]"
"[EXTRA]\n")
("\\section{%s}" . "\\section*{%s}")
("\\subsection{%s}" . "\\subsection*{%s}")
("\\subsubsection{%s}" . "\\subsubsection*{%s}"))
#+END_SRC
Both these classes have to be added to ~org-latex-classes~ like so:
#+NAME: org-latex-classes
#+BEGIN_SRC emacs-lisp :noweb yes
(eval-after-load "ox-latex"
'(progn
(add-to-list 'org-latex-classes
<<org-latex-class-conlang>>
)
(add-to-list 'org-latex-classes
<<org-latex-class-beamer>>
)))
#+END_SRC
**** Projects
:PROPERTIES:
:header-args:emacs-lisp: :tangle no :exports code :results silent
:END:
Another great features of Org-mode is the Org projects that allow the user to
easily publish a bunch of org files to a remote location. Here is the current
declaration of my projects, which will be detailed later:
#+NAME: org-publish-projects
#+BEGIN_SRC emacs-lisp :noweb yes
<<org-proj-config-setup>>
<<org-proj-lang-setup>>
(setq org-publish-project-alist
`(
<<org-proj-config-html>>
<<org-proj-config-static>>

<<org-proj-lang-html>>
<<org-proj-lang-pdf>>
<<org-proj-lang-static>>
<<org-proj-lang>>))
#+END_SRC
***** 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.
#+NAME: org-proj-config-setup
#+BEGIN_SRC emacs-lisp

(defvar phundrak//projects-config-recursive
t
"Defines whether subdirectories should be parsed for config.phundrak.com")
#+END_SRC
Now, here is my configuration. In this snippet, my org files located in my
source directory get exported in the HTML format and published to my target
directory on my remote server through RSYNC via TRAMP. A sitemap is
automatically generated, which comes in handy with the online sitemap that is
available through the navigation bar.
#+NAME: org-proj-config-html
#+BEGIN_SRC emacs-lisp

#+END_SRC
We also have the component for all the static files needed to run the website
(mostly images tbh).
#+NAME: org-proj-config-static

#+NAME: org-proj-config
#+BEGIN_SRC emacs-lisp

:components ("config-website-org"

#+END_SRC
***** Linguistics website
My linguistics website is made out of three projects. As for the previous
project, let’s declare the common values for these.
#+NAME: org-proj-lang-setup
#+BEGIN_SRC emacs-lisp
(defvar phundrak//projects-conlanging-target

"Points to where the sources for langue.phundrak.com are")
(defvar phundrak//projects-conlanging-language
"fr"
"Language of langue.phundrak.com")
(defvar phundrak//projects-conlanging-recursive
t
"Defines whether subdirectories should be parsed for langue.phundrak.com")
#+END_SRC
The first component is the one generating the HTML files from the org files.
#+NAME: org-proj-lang-html

#+END_SRC
**** Visual Configuration
While most modes of Emacs are dedicated to development, and therefore
are much more comfortable with a fixed-pitch font, more literary modes
such as org-mode are much more enjoyable if you have a variable pitch
font enabled. *BUT*, these modes can also require some fixed-pitch fonts
for some elements of the buffer, such as code blocks with
org-mode. ~mixed-pitch~ comes to the rescue!
#+begin_src emacs-lisp
(use-package mixed-pitch
:after org
:straight t

:config
(add-hook 'org-agenda-mode-hook (lambda () (mixed-pitch-mode -1))))
#+end_src
I have an issue with org-mode’s emphasis markers: I find them ugly. I
can of course hide them if I simply set ~org-hide-emphasis-markers~ to
~t~, but it makes editing hard since I never know whether I am before or
after the emphasis marker when editing near the beginning/end of an
emphasized region. ~org-appear~ fixes this issue so that it shows the
emphasis markers only when the cursor is in the emphasized region,
otherwise they will remain hidden! Very cool!
#+begin_src emacs-lisp
(use-package org-appear
:after org
:straight (:build t)
:hook (org-mode . org-appear-mode)
:config
(setq org-appear-autoemphasis t

Tired of seeing lots of actual stars ~*~ in your headers, and you want a
fancier remplacement? Or you are still using ~org-bullets~ but just
found out how out-of-date and abandoned it is? (Last commit was on
September 18th, 2014… damn…) Search no more, ~org-superstar~ will take
care of that for you!
#+begin_src emacs-lisp

#+end_src
~org-fancy-priorities~ change the priority of an org element such such
as ~#A~ to anything user-defined. Let’s make this anything all-the-icons
icons!
#+begin_src emacs-lisp

files at the top of your window.
#+begin_src emacs-lisp

*** Tramp
Tramp is an Emacs built-in package that allows the user to connect to
various hosts using various protocols, such as ~ssh~ and
~rsync~. However, I have some use-case for Tramp which are not
supported natively. I will describe them here.
#+begin_src emacs-lisp
(require 'tramp)
#+end_src
**** Yadm
# ~yadm~ is the utility I use for managing my dotfiles, and it is a wrapper In
# order to manage my dotfiles, I use the following shortcut to launch Magit Status
# for ~yadm~:
[[https://yadm.io/][~yadm~]] is a git wrapper made to easily manage your dotfiles. It has
loads of features I don’t use (the main one I like but don’t use is
its [[https://yadm.io/docs/templates][Jinja-like host and OS-aware syntax]]), but unfortunately Magit
doesn’t play nice with it. Tramp to the rescue, and this page explains
how! Let’s just insert in my config this code snippet:
#+begin_src emacs-lisp
(add-to-list 'tramp-methods
'("yadm"
(tramp-login-program "yadm")

** Making my life easier
*** 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.
#+begin_src emacs-lisp
(use-package bufler
:straight (bufler :build t
:files (:defaults (:exclude "helm-bufler.el")))
:defer t
:general
(:keymaps 'bufler-list-mode-map

*** Helpful
As the name tells, ~helpful~ is a really helpful package which greatly
enhances a couple of built-in functions from Emacs, namely:
| Vanilla Emacs Function | Helpful Function | Comment |
|------------------------+------------------+-----------------------------------------------|
| ~describe-function~ | ~helpful-callable~ | Only interactive functions |
| ~describe-function~ | ~helpful-function~ | Only actual functions (including interactive) |
| ~describe-function~ | ~helpful-macro~ | |
| ~describe-command~ | ~helpful-command~ | |
| ~describe-key~ | ~helpful-key~ | |
| ~describe-variable~ | ~helpful-variable~ | |
#+begin_src emacs-lisp

** 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!
#+begin_src emacs-lisp
(use-package magit
:straight (:build t)
:defer t
:custom

#+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.
#+begin_src emacs-lisp
(use-package magit-todos
:straight (:build t)

package!

#+end_src
** Programming languages
*** DSLs
DSLs, or /Domain Specific Languages/, are languages dedicated to some
very tasks, such as configuration languages or non-general programming
such as SQL.
**** Shells
Aside from Eshell, my main shell on my machine is fish (see my [[file:fish.org][fish
config]]), therefore I need a mode for it.
#+begin_src emacs-lisp
(use-package fish-mode
:straight (:build t)
:defer t)
#+end_src
**** Caddy
[[https://caddyserver.com/][Caddy]] (or /Caddyserver/) is a web server akin to Nginx or Apache which I
find much easier to configure that the latter two, plus it has
built-in support for automatically generating SSL certificates with
Letsencrypt! Automatic HTTPS, what more do you want?
All that is nice and all, but Emacs doesn’t support the syntax of
Caddy files natively, so let’s install ~caddyfile-mode~:
#+begin_src emacs-lisp
(use-package caddyfile-mode
:defer t
:straight (:build t)
:mode (("Caddyfile\\'" . caddyfile-mode)
("caddy\\.conf\\'" . caddyfile-mode)))
#+end_src
**** Nginx
Nginx is another webserver, older and more mature than Caddy. A couple
of packages are required in order to be able to properly work with
Nginx configuration files. First, we need the correct mode for editing
Nginx configuration files.
#+begin_src emacs-lisp
(use-package nginx-mode
:straight (:build t)
:defer t)
#+end_src
We then also have an autocompletion package that adds to ~company~ the
Nginx syntax.
#+begin_src emacs-lisp
(use-package company-nginx
:straight (:build t)
:defer t
:config
(add-hook 'nginx-mode-hook (lambda ()
(add-to-list 'company-backends #'company-nginx))))
#+end_src
**** Yaml
#+begin_src emacs-lisp
(use-package yaml-mode

*** Flycheck
#+begin_src emacs-lisp

;; Rerunning checks on every newline is a mote excessive.

;; And don’t recheck on idle as often
(setq flycheck-idle-change-delay 2.0)
;; For the above functionality, check syntax in a buffer that you

;; state for several buffers quickly after e.g. changing a config
;; file.
(setq flycheck-buffer-switch-check-intermediate-buffers t)

*** General Programming Languages
**** EmacsLisp
This package displays the function’s arglist or variable’s docstring

*** Icons? Did someone say icons?
/*YES! ALL OF THEM!*/
Ahem…
The package ~all-the-icons~ allows us to use a wide variety of icons in
Emacs for various purposes, wherever we want, and /THAT/ is *GREAT*! I’ll
(ab)use this feature in my config, be warned! *NOTE*: The first time a
configuration with ~all-the-icons~ is loaded on a machine, the needed
fonts might not be available, so you’ll need to install them with the
command ~M-x all-the-icons-install-fonts~.
#+begin_src emacs-lisp
(use-package all-the-icons
:defer t)
#+end_src
~prettify-symbols-mode~ is also a nifty feature of Emacs, and it is
built-in! With that, I can replace strings of my choice by another
character of my choice!
#+begin_src emacs-lisp
(dolist (symbol '(("lambda" . 955)
("mapc" . 8614)))
(add-to-list 'prettify-symbols-alist symbol))
#+end_src
Let’s enable this mode for any programming mode:
#+begin_src emacs-lisp

#+end_src
*** Rainbow Delimiters
#+begin_src emacs-lisp

*** Y’all want some more /COLORS/?
It is possible to make info buffers much more colorful (and imo easier to read) with this simple package:
#+begin_src emacs-lisp

:config
(setq avy-keys '(?a ?u ?i ?e ?c ?t ?s ?r ?n))

#+begin_src emacs-lisp

#+begin_src emacs-lisp

#+end_src
*** Winum
Winum allows Emacs to associate windows with a specific number and
navigate through these windows by directly refering to their
associated number! This allows for faster window configuration than
just going to the frame above, then left, left, and up.
#+begin_src emacs-lisp
