** 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.

This package is a backend for company. It emulates
~ac-source-dictionary~ by proposing text related to the current
major-mode.
#+begin_src emacs-lisp

#+end_src
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.

** 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=.
#+begin_src emacs-lisp
(use-package ivy
:straight t
:defer t
:diminish
:bind (("C-s" . swiper)
:map ivy-minibuffer-map

#+end_src
There is also [[https://github.com/raxod502/prescient.el][~prescient.el~]] that offers some nice features when
coupled with ~ivy~, guess what was born out of it? ~ivy-prescient~, of
course!
#+begin_src emacs-lisp
(use-package ivy-prescient
:after ivy
:straight (:build t))
#+end_src
I warned you I’d use too much ~all-the-icons~, I did!
#+begin_src emacs-lisp
(use-package all-the-icons-ivy
:straight (:build t)
:after (ivy all-the-icons)
:init (all-the-icons-ivy-setup)
:hook (after-init . all-the-icons-ivy-setup))
(all-the-icons-ivy-setup)
#+end_src
A buffer popping at the bottom of the screen is nice and all, but have
you considered a floating buffer in the center of your frame?
#+begin_src emacs-lisp
(use-package ivy-posframe
:defer t
:after (:any ivy helpful)
:hook (ivy-mode . ivy-posframe-mode)
:straight (:build t)
:init
(ivy-posframe-mode 1)
:config
(setq ivy-fixed-height-minibuffer nil
ivy-posframe-border-width 10
ivy-posframe-parameters
`((min-width . 90)
(min-height . ,ivy-height))))
#+end_src
Something that can be missing sometimes in Ivy is the ability to
select multiple entries at once. For instance, when programming in
Java, LPS can offer you to automatically generate the methods ~equals~
and ~hashCode~ based on selected members, but with vanilla Ivy, you can
only select one. Not really useful. ~ivy-hydra~ is a package that offers
a Hydra interface when in Ivy which allows you to select multiple
choices among other things.
#+begin_src emacs-lisp
(use-package ivy-hydra
:requires (ivy hydra)
:after ivy
:straight (:build t))
#+end_src
Finally, let’s make ~ivy~ richer:
#+begin_src emacs-lisp
(use-package ivy-rich
:straight (:build t)
:after ivy
:init
(ivy-rich-mode 1))
#+end_src
** Counsel
I could almost merge this chapter with the previous one since counsel
is a package that provides loads of completion functions for ivy. The
ones I find most useful are ~counsel-M-x~ and ~counsel-find-file~.
#+begin_src emacs-lisp
(use-package counsel
:straight 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)))
#+end_src
** 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.
#+begin_src emacs-lisp
(use-package yasnippet
:defer t
:straight (:build t)
:init
(yas-global-mode)
:hook ((prog-mode . yas-minor-mode)
(text-mode . yas-minor-mode)))
#+end_src
Of course, yasnippet wouldn’t be as awesome as it is without pre-made
snippets.
#+begin_src emacs-lisp
(use-package yasnippet-snippets
:defer t
:after yasnippet
:straight (:build t))
#+end_src
Similarly, yatemplate offers pre-made files rather than just strings.
That’s still yasnippet by the way.
#+begin_src emacs-lisp
(use-package yatemplate
:defer t
:after yasnippet
:straight (:build t))
#+end_src
And finally, with ivy you can choose your snippets from a menu if
you’re not sure or if you don’t remember what your snippet is.
#+begin_src emacs-lisp
(use-package ivy-yasnippet
:defer t
:after (ivy yasnippet)
:straight (:build t)
:general
(phundrak/leader-key
:infix "i"
:packages 'ivy-yasnippet
"y" #'ivy-yasnippet))

** Atomic Chrome
Why write in your browser when you could write with Emacs? Despite its
name, this package isn’t only geared towards Chrome/Chromium-based
browsers but also towards Firefox since its 2.0 version. I find it a
bit unfortunate Chrome’s name stuck in the package’s name though.
#+begin_src emacs-lisp

** Editorconfig
Editorconfig is a unified way of passing to your text editor settings
everyone working in a repo need to follow. ~.editorconfig~ files work
for VSCode users, vim users, Atom users, Sublime users, and of course
Emacs users.
#+begin_src emacs-lisp

enough for me.
#+begin_src emacs-lisp
(use-package evil-nerd-commenter
:after evil
:straight (:build t))
#+end_src
** Iedit
Iedit is a powerful text editing tool that can be used to refactor
code through the edition of multiple regions at once, be it in a
region or in a whole buffer. Since I’m using evil, I’ll also use a
compatibility package that adds states for iedit.
#+begin_src emacs-lisp

** Smartparens
#+begin_src emacs-lisp

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

:general
(phundrak/major-leader-key
:keymaps 'parinfer-rust-mode-map
"m" #'parinfer-rust-switch-mode
"M" #'parinfer-rust-toggle-disable))
#+end_src
** Smartparens
~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.
#+begin_src emacs-lisp
(use-package smartparens
:defer t
:straight (smartparens :build t
:type git
:host github
:repo "Fuco1/smartparens")
:hook (prog-mode . smartparens-mode))
#+end_src
** ~string-edit~
~string-edit~ is a cool package that allows the user to write naturally
a string and get it automatically escaped for you. No more manually
escaping your strings!
#+begin_src emacs-lisp
(use-package string-edit-at-point
:defer t
:straight (:build t))
#+end_src
** Writeroom
On the other hand, ~writeroom~ allows the user to enter a
distraction-free mode of Emacs, and I like that! But the default width
is a bit too small for me, and I prefer not to go fullscren.
#+begin_src emacs-lisp
(use-package writeroom-mode
:defer t
:straight (:build t)
:init (global-writeroom-mode 1)

(setq writeroom-width 100

** 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!

It requires some programs which can be installed like so:
#+begin_src sh :dir /sudo::~/ :exports code :tangle no :results verbatim
pacman -S --needed --noprogressbar --noconfirm --color=never \
fd poppler ffmpegthumbnailer mediainfo imagemagick tar unzip
#+end_src
Since Emacs 29, it is possible to enable drag-and-drop between Emacs
and other applications.
#+name: dired-drag-and-drop
#+begin_src emacs-lisp :tangle no
(csetq dired-mouse-drag-files t
mouse-drag-and-drop-region-cross-program t)
#+end_src
In Dirvish, it’s best to use the long name of flags whenever possible,
otherwise some commands won’t work.
#+name: dired-listing-flags
#+begin_src emacs-lisp :tangle no
(csetq dired-listing-switches (string-join '("--all"
"--human-readable"
"--time-style=long-iso"
"--group-directories-first"
"-lv1")
" "))
#+end_src
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.
#+name: dirvish-exa-offload
#+begin_src emacs-lisp :tangle no
(dirvish-define-preview exa (file)
"Use `exa' to generate directory preview."
:require ("exa")
(when (file-directory-p file)
`(shell . ("exa" "--color=always" "-al" ,file))))
(add-to-list 'dirvish-preview-dispatchers 'exa)
#+end_src
Finally, some directories need to be set for Dired to store various
files and images.
#+name: dired-files-and-dirs
#+begin_src emacs-lisp :tangle no
(let ((my/file (lambda (path &optional dir)
(expand-file-name path (or dir user-emacs-directory))))
(my/dir (lambda (path &optional dir)
(expand-file-name (file-name-as-directory path)
(or dir user-emacs-directory)))))
(csetq image-dired-thumb-size 150
image-dired-dir (funcall my/dir "dired-img")
image-dired-db-file (funcall my/file "dired-db.el")
image-dired-gallery-dir (funcall my/dir "gallery")
image-dired-temp-image-file (funcall my/file "temp-image" image-dired-dir)
image-dired-temp-rotate-image-file (funcall my/file "temp-rotate-image" image-dired-dir)))
#+end_src
Copying files with Dired is a blocking process. It’s usually fine when
there’s not a lot to copy, but it becomes annoying when moving larger
files. The package ~dired-rsync~ allows copying files with ~rsync~ in the
background; we can then carry on with our tasks while the copy is
happening.
#+begin_src emacs-lisp
(use-package dired-rsync
:if (executable-find "rsync")
:defer t
:straight (:build t)
:general

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

** Eshell
[[file:../img/emacs-eshell.svg]]
Eshell is a built-in shell available from Emacs which I use almost as
often as fish. Some adjustments are necessary to make it fit my taste
though.
#+begin_src emacs-lisp
(use-package eshell
:defer t
:straight (:type built-in :build t)
:config
(setq eshell-prompt-function
(lambda ()
(concat (abbreviate-file-name (eshell/pwd))
(if (= (user-uid) 0) " # " " λ ")))
eshell-prompt-regexp "^[^#λ\n]* [#λ] ")
<<eshell-alias-file>>
<<eshell-concat-shell-command>>
<<eshell-alias-open>>

(phundrak/evil
:keymaps 'eshell-mode-map
[remap evil-collection-eshell-evil-change] #'evil-backward-char

:keymaps 'eshell-mode-map
:states 'insert

#+end_src
*** Aliases
First, let’s declare our list of “dumb” aliases we’ll use in
Eshell. You can find them here.
#+name: eshell-alias-file
#+begin_src emacs-lisp :tangle no
(setq eshell-aliases-file (expand-file-name "eshell-alias" user-emacs-directory))
#+end_src
A couple of other aliases will be defined through custom Elisp
functions, but first I’ll need a function for concatenating a shell
command into a single string:
#+name: eshell-concat-shell-command
#+begin_src emacs-lisp :tangle no
(defun phundrak/concatenate-shell-command (&rest command)
"Concatenate an eshell COMMAND into a single string.
All elements of COMMAND will be joined in a single
space-separated string."
(mapconcat #'identity command " "))
#+end_src
I’ll also declare some aliases here, such as ~open~ and ~openo~ that
respectively allow me to open a file in Emacs, and same but in another
window.
#+name: eshell-alias-open
#+begin_src emacs-lisp :tangle no
(defalias 'open #'find-file)
(defalias 'openo #'find-file-other-window)
#+end_src
The default behavior of ~eshell/clear~ is not great at all, although it
clears the screen it also scrolls all the way down. Therefore, let’s
alias it to ~eshell/clear-scrollback~ which has the correct behavior.
#+name: eshell-alias-clear
#+begin_src emacs-lisp :tangle no
(defalias 'eshell/clear #'eshell/clear-scrollback)
#+end_src
As you see, these were not declared in my dedicated aliases file but
rather were declared programmatically. This is because I like to keep
my aliases file for stuff that could work too with other shells were
the syntax a bit different, and aliases related to Elisp are kept
programmatically. I’ll also declare ~list-buffers~ an alias of ~ibuffer~
because naming it that way kind of makes more sense to me.
#+name: eshell-alias-buffers
#+begin_src emacs-lisp :tangle no
(defalias 'list-buffers 'ibuffer)
#+end_src
I still have some stupid muscle memory telling me to open ~emacs~, ~vim~
or ~nano~ in Eshell, which is stupid: I’m already inside Emacs and I
have all its power available instantly. So, let’s open each file
passed to these commands.
#+name: eshell-alias-emacs
#+begin_src emacs-lisp :tangle no
(defun eshell/emacs (&rest file)
"Open each FILE and kill eshell.
Old habits die hard."
(when file
(dolist (f (reverse file))
(find-file f t))))
#+end_src
Finally, I’ll declare ~mkcd~ which allows the simultaneous creation of a
directory and moving into this newly created directory. And of course,
it will also work if the directory also exists or if parent
directories don’t, similarly to the ~-p~ option passed to ~mkdir~.
#+name: eshell-alias-mkcd
#+begin_src emacs-lisp :tangle no
(defun eshell/mkcd (dir)
"Create the directory DIR and move there.
If the directory DIR doesn’t exist, create it and its parents
if needed, then move there."
(mkdir dir t)
(cd dir))
#+end_src
*** 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:
#+BEGIN_SRC emacs-lisp
(defadvice find-file (around find-files activate)
"Also find all files within a list of files. This even works recursively."
(if (listp filename)
(cl-loop for f in filename do (find-file f wildcards))
ad-do-it))
#+END_SRC
I also want to be able to have multiple instances of Eshell opened at
once. For that, I declared the function ~eshell-new~ that does exactly
that.
#+begin_src emacs-lisp
(defun eshell-new ()
"Open a new instance of eshell."
(interactive)
(eshell 'N))
#+end_src
A very useful command I often use in fish is ~z~, a port from bash’s and
zsh’s command that allows to jump around directories based on how
often we go in various directories.
#+begin_src emacs-lisp
(use-package eshell-z
:defer t
:after eshell
:straight (:build t)
:hook (eshell-mode . (lambda () (require 'eshell-z))))
#+end_src
*** Environment Variables
Some environment variables need to be correctly set so Eshell can
correctly work. I would like to set two environment variables related
to Dart development: the ~DART_SDK~ and ~ANDROID_HOME~ variables.
#+BEGIN_SRC emacs-lisp
(setenv "DART_SDK" "/opt/dart-sdk/bin")
(setenv "ANDROID_HOME" (concat (getenv "HOME") "/Android/Sdk/"))
#+END_SRC
The ~EDITOR~ variable also needs to be set for git commands, especially the
~yadm~ commands.
#+BEGIN_SRC emacs-lisp
(setenv "EDITOR" "emacsclient -c -a emacs")
#+END_SRC
Finally, for some specific situations I need ~SHELL~ to be set to
something more standard than fish:
#+begin_src emacs-lisp
(setenv "SHELL" "/bin/sh")
#+end_src
*** Visual configuration
I like to have at quick glance some information about my machine when
I fire up a terminal. I haven’t found anything that does that the way
I like it, so [[https://github.com/Phundrak/eshell-info-banner.el][I’ve written a package]]! It’s actually available on
MELPA, but since I’m the main dev of this package, I’ll keep track of
the git repository.
#+begin_src emacs-lisp
(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)
:custom-face
(eshell-info-banner-normal-face ((t :foreground "#A3BE8C")))
(eshell-info-banner-background-face ((t :foreground "#E5E9F0")))
(eshell-info-banner-warning-face ((t :foreround "#D08770")))
(eshell-info-banner-critical-face ((t :foreground "#BF616A")))
:custom
(eshell-info-banner-partition-prefixes (list "/dev" "zroot" "tank")))
#+end_src
Another feature I like is fish-like syntax highlight, which brings
some more colors to Eshell.
#+begin_src emacs-lisp
(use-package eshell-syntax-highlighting
:after (esh-mode eshell)
:defer t
:straight (:build t)
:config
(eshell-syntax-highlighting-global-mode +1))
#+end_src
Powerline prompts are nice, git-aware prompts are even better!
~eshell-git-prompt~ is nice, but I prefer to write my own package for
that.
#+begin_src emacs-lisp
(use-package powerline-eshell
:if (string= (string-trim (shell-command-to-string "uname -n")) "leon")
:load-path "~/fromGIT/emacs-packages/powerline-eshell.el/"
:after eshell)
#+end_src
** Eww
Since Emacs 29, it is possible to automatically rename ~eww~ buffers to
a more human-readable name, see [[https://protesilaos.com/codelog/2021-10-15-emacs-29-eww-rename-buffers/][Prot’s blog]] post on the matter.
#+begin_src emacs-lisp
(use-package eww
:defer t
:straight (:type built-in)
:config
(setq eww-auto-rename-buffer 'title))
#+end_src
** Image-mode
I won’t modify much for ~image-mode~ (the mode used to display images)
aside from Emacs’ ability to use external converters to display some
images it wouldn’t be able to handle otherwise.
#+begin_src emacs-lisp
(setq image-use-external-converter t)
#+end_src
** Info
Let’s define some more intuitive keybinds for ~info-mode~.
#+begin_src emacs-lisp
(use-package info
:defer t
:straight (info :type built-in :build t)
:general
(phundrak/evil
:keymaps 'Info-mode-map
"c" #'Info-prev
"t" #'evil-scroll-down
"s" #'evil-scroll-up
"r" #'Info-next)
(phundrak/major-leader-key
:keymaps 'Info-mode-map
"?" #'Info-toc
"b" #'Info-history-back
"f" #'Info-history-forward
"m" #'Info-menu
"t" #'Info-top-node
"u" #'Info-up))
#+end_src
** Tab Bar
#+begin_src emacs-lisp
(use-package tab-bar
:defer t
:straight (:type built-in)
:custom
(tab-bar-close-button-show nil)
(tab-bar-new-button-show nil)
(tab-bar-new-tab-choice "*dashboard*")
:custom-face
(tab-bar ((t (:background "#272C36"
:foreground "#272C36"
:box (:line-width (8 . 5) :style flat-button)))))
:init
(advice-add #'tab-new
:after
(lambda (&rest _) (when (y-or-n-p "Rename tab? ")
(call-interactively #'tab-rename)))))
#+end_src
** 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
(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)))
#+end_src
*** 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:
#+name: tramp-add-yadm
#+begin_src emacs-lisp :tangle no
(add-to-list 'tramp-methods
'("yadm"
(tramp-login-program "yadm")
(tramp-login-args (("enter")))
(tramp-login-env (("SHELL") ("/bin/sh")))
(tramp-remote-shell "/bin/sh")
(tramp-remote-shell-args ("-c"))))
#+end_src
I’ll also create a fuction for connecting to this new Tramp protocol:
#+begin_src emacs-lisp
(defun my/yadm ()
"Manage my dotfiles through TRAMP."
(interactive)
(magit-status "/yadm::"))
#+end_src

* 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.
#+begin_src emacs-lisp
(use-package xelb
:if (seq-contains-p command-line-args "--with-exwm")
:straight (xelb :build t
:type git
:host github
:repo "emacs-straight/xelb"
:fork "ch11ng/xelb"))
#+end_src
Next is a function I’ve +stolen+ copied from Daviwil’s [[https://config.daviwil.com/desktop][desktop
configuration]]. This allows to launch software in the background
easily.
#+begin_src emacs-lisp
(defun exwm/run-in-background (command &optional once)
(let ((command-parts (split-string command " +")))
(apply #'call-process `(,(car command-parts) nil 0 nil ,@(cdr command-parts)))))
#+end_src
In order to launch Emacs with EXWM with ~startx~, I need a ~xinit~ file.
This one is exported to ~$HOME/.xinitrc.emacs~.
#+begin_src sh :tangle ~/.xinitrc.emacs :shebang "#!/bin/sh"
xhost +SI:localuser:$USER
# Set fallback cursor
xsetroot -cursor_name left_ptr
# If Emacs is started in server mode, `emacsclient` is a convenient
# way to edit files in place (used by e.g. `git commit`)
export VISUAL=emacsclient
export EDITOR="$VISUAL"
# in case Java applications display /nothing/
# wmname LG3D
# export _JAVA_AWT_WM_NONREPARENTING=1
autorandr -l home
exec emacs --with-exwm
#+end_src
** EXWM 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, I added in the ~:config~ secion to two hooks functions
that rename buffers accurately. While the average X window will simply
get the name of the current X window, I want Firefox and Qutebrowser
to be prefixed with the name of the browser. Actually, all these will
be renamed this way:
#+name: exwm-renamed-buffers-list
- Kitty
- Qutebrowser
#+name: exwm-gen-buffers-rename
#+header: :exports none :tangle no
#+begin_src emacs-lisp :var buffers=exwm-renamed-buffers-list :cache yes
(format "%s\n%S"
(mapconcat (lambda (buffer)
(let ((buffer-name (if (stringp buffer)
buffer
(car buffer))))
(format "(\"%s\" %S)"
(downcase buffer-name)
`(exwm-workspace-rename-buffer
(concat ,(concat "EXWM: " buffer-name " - ")
exwm-title)))))
buffers
"\n")
'(_otherwise (exwm-workspace-rename-buffer exwm-title)))
#+end_src
#+RESULTS[64fdbf1e8957b82aad801ec57f2155a0a8f5be54]: exwm-gen-buffers-rename
: ("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))
#+name: exwm-buffers-name
#+begin_src emacs-lisp :tangle no
(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()>>)))
#+end_src
As you can see below, in the ~:config~ section I added two advices and
one hook in order to correctly integrate evil with EXWM. When I’m in
an X window, I want to be in insert-mode in order to type however I
want. However, when I exit one, I want to default back to normal-mode.
#+name: exwm-advices-evil
#+begin_src emacs-lisp :tangle no
(add-hook 'exwm-manage-finish-hook (lambda () (call-interactively #'exwm-input-release-keyboard)))
(advice-add #'exwm-input-grab-keyboard :after (lambda (&optional id) (evil-normal-state)))
(advice-add #'exwm-input-release-keyboard :after (lambda (&optional id) (evil-insert-state)))
#+end_src
Secondly, I add ~i~, ~C-SPC~, and ~M-m~ as exwm prefix keys so they aren’t
sent directly to the X windows but caught by Emacs (and EXWM). I’ll
use the ~i~ key in normal-mode to enter ~insert-mode~ and have Emacs
release the keyboard so the X window can grab it. Initially, I had
~s-<escape>~ as a keybind for grabbing back the keyboard from an X
window, as if I were in insert mode and wanted to go back to normal
mode, and I had ~s-I~ to toggle keyboard grabbing. But I found myself
more than once trying to use ~s-<escape>~ to toggle this state, ~s-I~
completely forgotten. So I removed ~s-I~ and made ~s-<escape>~ behave like
~s-I~ once did.
#+name: exwm-prefix-keys
#+begin_src emacs-lisp :tangle no
(general-define-key
:keymaps 'exwm-mode-map
:states 'normal
"i" #'exwm-input-release-keyboard)
(exwm-input-set-key (kbd "s-<escape>") #'exwm-input-toggle-keyboard)
(push ?\i exwm-input-prefix-keys)
(push (kbd "C-SPC") exwm-input-prefix-keys)
(push (kbd "M-m") exwm-input-prefix-keys)
#+end_src
As stated a couple of times in my different configuration files, I’m
using the bépo layout, which means the default keys in the number row
are laid as follows:
#+name: exwm-bepo-number-row
#+begin_src emacs-lisp :tangle no
(defconst exwm-workspace-keys '("\"" "«" "»" "(" ")" "@" "+" "-" "/" "*"))
#+end_src
With this, we can create keybinds for going or sending X windows to
workspaces 0 to 9.
#+name: exwm-workspace-keybinds
#+begin_src emacs-lisp :tangle no
(setq exwm-input-global-keys
`(,@exwm-input-global-keys
,@(mapcar (lambda (i)
`(,(kbd (format "s-%s" (nth i exwm-workspace-keys))) .
(lambda ()
(interactive)
(exwm-workspace-switch-create ,i))))
(number-sequence 0 9))
,@(mapcar (lambda (i)
`(,(kbd (format "s-%d" i)) .
(lambda ()
(interactive)
(exwm-workspace-move-window ,(let ((index (1- i)))
(if (< index 0)
(- 10 index)
;; FIXME: does not work with s-0
index))))))
(number-sequence 0 9))))
#+end_src
You can then see the list of the keybinds I have set for EXWM, which
are all prefixed with ~SPC x~ in normal mode (and ~C-SPC x~ in insert
mode), except for ~s-RET~ which opens an eshell terminal.
#+name: exwm-keybinds

** Bufler
Bufler is a package that organises 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.

** Helpful
As the name tells, ~helpful~ is a really helpful package which greatly
enhances a couple of built-in functions from Emacs, namely:

| ~describe-function~ | ~helpful-callable~ | Only interactive functions |
| ~describe-function~ | ~helpful-function~ | Only actual functions (including interactive) |
| ~describe-function~ | ~helpful-macro~ | |

Emacs for various purposes, wherever we want, and /THAT/ is *GREAT*! I’ll
(ab)use this feature in my config, be warned! *NOTE*: The first time a
configuration with ~all-the-icons~ loads on a machine, the needed fonts
might not be available, so you’ll need to install them with the
command ~M-x all-the-icons-install-fonts~.
#+begin_src emacs-lisp
(use-package all-the-icons
:defer t
:straight t)
#+end_src
~prettify-symbols-mode~ is also a nifty feature of Emacs, and it is
built-in! With that, I can replace strings of my choice by another
character of my choice! First, let’s declare the general symbols that
will be used everywhere.
#+begin_src emacs-lisp
(defun prog-mode-set-symbols-alist ()
(setq prettify-symbols-alist '(("lambda" . ?λ)))
(prettify-symbols-mode 1))
(add-hook 'prog-mode-hook #'prog-mode-set-symbols-alist)
#+end_src
We can now take care of the language-specific symbols. First, let’s
declare some symbols for the Lisp languages.
#+begin_src emacs-lisp
(setq-default lisp-prettify-symbols-alist '(("lambda" . ?λ)
("defun" . ?𝑓)
("defvar" . ?𝑣)
("defcustom" . ?𝑐)
("defconst" . ?𝐶)))
(defun lisp-mode-prettify ()
(setq prettify-symbols-alist lisp-prettify-symbols-alist)
(prettify-symbols-mode -1)
(prettify-symbols-mode 1))
(dolist (lang '(emacs-lisp lisp common-lisp scheme))
(add-hook (intern (format "%S-mode-hook" lang))
#'lisp-mode-prettify))
#+end_src
Finally, similar to how ~org-appear~ behaves, let’s show the real string
of our symbols when the cursor is on it.
#+begin_src emacs-lisp
(setq prettify-symbols-unprettify-at-point t)
#+end_src
** Ligatures
The font I’m using (see *here*) supports ligatures, but Emacs in GUI
mode does not. And of course, there’s a package for that.
# Insert equivalent of #Basic-configuration-Visual-Configuration-Fontsxfkjel6184j0 in *here*
#+begin_src emacs-lisp
(use-package ligature
:straight (ligature :type git
:host github
:repo "mickeynp/ligature.el"
:build t)
:config
(ligature-set-ligatures 't
'("www"))
;; Enable traditional ligature support in eww-mode, if the
;; `variable-pitch' face supports it
(ligature-set-ligatures '(eww-mode org-mode elfeed-show-mode)
'("ff" "fi" "ffi"))
;; Enable all Cascadia Code ligatures in programming modes
(ligature-set-ligatures 'prog-mode
'("|||>" "<|||" "<==>" "<!--" "####" "~~>" "***" "||=" "||>"
":::" "::=" "=:=" "===" "==>" "=!=" "=>>" "=<<" "=/=" "!=="
"!!." ">=>" ">>=" ">>>" ">>-" ">->" "->>" "-->" "---" "-<<"
"<~~" "<~>" "<*>" "<||" "<|>" "<$>" "<==" "<=>" "<=<" "<->"

"\\\\" "://"))
(global-ligature-mode t))
#+end_src
** Modeline
The DoomEmacs modeline looks nice in my opinion, let’s use it.
#+begin_src emacs-lisp
(use-package doom-modeline
:straight (:build t)
:defer t
:init (doom-modeline-mode 1)
:config
(csetq doom-modeline-height 15
doom-modeline-enable-word-count t
doom-modeline-continuous-word-count-modes '(markdown-mode gfm-mode org-mode)
doom-modeline-mu4e t
doom-modeline-env-version t)
(mu4e-alert-enable-mode-line-display))
#+end_src
** Pixel-perfect alignment of Markdown and org-mode tables
:END:
Usually, I have no issue with the alignment of the tables I write in
org-mode and (more rarely) Markdown. However, there are occurences
where I’ll use a character that does not exactly respect my monospace
font, which messes with the alignment of the table (often when I do
linguistics stuff). A solution to this is the package ~valign~. A little
caveat though, as its name implies ~valign~ helps with vertical
alignment. If some lines are too high, they won’t exactly fit. Unless?
Unless ~valign-fancy-bar~ is set to ~t~.
For now, I disabled the hook with org-mode and markdown-mode because
it slows down opening these files quite a lot. I’ll re-enable the hook
once it is fixed.
#+begin_src emacs-lisp
(use-package valign
:defer t
:straight (:build t)
:after (org markdown-mode)
;; :hook ((org-mode markdown-mode) . valign-mode)
:custom ((valign-fancy-bar t)))
#+end_src
** Secret mode
Sometimes, I want to hide the text displayed by Emacs but not lock
altogether my computer. In this case, ~secret-mode~ comes in handy.
#+begin_src emacs-lisp
(use-package secret-mode
:defer t
:straight (secret-mode :build t
:type git
:host github
:repo "bkaestner/secret-mode.el"))
#+end_src
** Solaire: Incandescent Emacs
A common issue when you have a lot of windows opened in Emacs is
sometimes there’s just too much. Is the first window source code? Is
the other one just an open email? Oh, let’s not forget the ~*Messages*~
buffer open next to another source buffer.
Solaire-mode applies a subtle but useful tweak to your current color
scheme: the background of programming buffers is slightly lighter than
the background of other buffers. (Or is it other buffers that have a
slightly darker background? I’m not sure.)
#+begin_src emacs-lisp
(use-package solaire-mode
:defer t
:straight (:build t)
:init (solaire-global-mode +1))
#+end_src
** Theme
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.
#+begin_src emacs-lisp
(use-package doom-themes
:straight (:build t)
:defer t
:init (load-theme 'doom-nord-aurora t))
#+end_src
** Rainbow Delimiters
This makes Lisp especially more readable, but it’s also nice to have
for any language that has delimiters like brackets too.
#+begin_src emacs-lisp
(use-package rainbow-delimiters
:straight (:build t)
:defer t
:hook (prog-mode . rainbow-delimiters-mode))
#+end_src
** 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
(use-package info-colors
:straight (:build t)
:commands info-colors-fnontify-node
:hook (Info-selection . info-colors-fontify-node)
:hook (Info-mode . mixed-pitch-mode))
#+end_src
