[Emacs] Better media control keybinds and `shell-command-and-echo'
`shell-command-and-echo' now takes an additional argument that will
prefix the output of its ECHO argument.
Also add documentation for the function

This commit removes keybind `SPC m P' in favor of only `SPC m p' which
toggles the state of MPD between play and pause.

Emacs Configuration

Introduction

STOP Read this first!

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

After a couple of years using Spacemacs and a failed attempt at switching to DoomEmacs, Im 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. Im still in the process of porting my Spacemacs configuration over here.

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

Emacs Behavior

Editing Text in Emacs

I never want to keep trailing spaces in my files, which is why Im doing this:

(add-hook 'before-save-hook #'whitespace-cleanup)

I dont understand why some people add two spaces behind a full stop, I sure dont. Lets 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 would usually be considered by Emacs a word can be understood as several modes, as in camelCase words, and allows us to jump words on this finer level.

(global-subword-mode 1)

Lastly, I want the default mode for Emacs to be Emacs Lisp.

(setq-default initial-major-mode 'emacs-lisp-mode)
Indentation

I dont 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, lets 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 tangeant here: I dont 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 dont work anymore! Or they may on your text editor but not on your coworkers! (Hes 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. Whats the best of both worlds then?

Tabs for indentation

Spaces for alignment

I havent found a way to automate that in Emacs yet aside from formatters config file, and tabs look bat in EmacsLisp anyways, so Ill stick with spaces by default and change it where needed.

Programming Modes

First off, my definition of what makes a a “programming mode” doesnt exactly fit mine, so on top of prog-mode, lets 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, lets 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 isnt 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.

(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) ; Dont 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 dont 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! Thats 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. Lets change this behavior:

(global-auto-revert-mode 1)

Much more polite! Note that if the buffer is modified and its changes havent been saved, it will not automatically revert the buffer and your unsaved changes wont be lost. Very polite!

Misc

Lets raise Emacs undo memory to 10MB, and make Emacs auto-save our files by default.

(setq undo-limit        100000000
      auto-save-default t)

Im also interested in keeping track of how fast Emacs loads on my computer, as well as for how long I keep it open. The values are stored in a .csv with three columns:

  • The date when Emacs was closed
  • Emacs init time
  • Emacs uptime
(defvar my/emacs-log-file-time (expand-file-name "emacs-time.csv" user-emacs-directory))

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

(add-to-list 'kill-emacs-hook #'my/write-emacs-loadtime-and-uptime)
(setq window-combination-resize t) ; take new window space from all other windows

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 havent 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 doesnt agree with, like tring to go up a line when Im 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. Lets make it so:

(setq truncate-string-ellipsis "…")

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).

(setq display-time-format "%Y-%m-%d %H:%M")
(display-time-mode 1) ; display time in modeline

Something my taskbar doesnt 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 isnt 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 Im 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 TECs 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, lets 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 dont like the default font I usually have on my machines, I really dont. I prefer Cascadia Code, as it also somewhat supports the IPA.

(defvar phundrak/default-font-size 90
  "Default font size.")

(when (equal system-type 'gnu/linux)
  (set-face-attribute 'default nil :font "Cascadia Code" :height phundrak/default-font-size))

Frame Title

This is straight-up copied from TECs 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") project-name))))))

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, Ill instead just copy their code here. First we get the after! macro:

(require 'cl-lib)
(defmacro after! (package &rest body)
  "Evaluate BODY after PACKAGE have loaded.

PACKAGE is a symbol or list of them. These are package names, not modes,
functions or variables. It can be:

- An unquoted package symbol (the name of a package)
    (after! helm BODY...)
- An unquoted list of package symbols (i.e. BODY is evaluated once both magit
  and git-gutter have loaded)
    (after! (magit git-gutter) BODY...)
- An unquoted, nested list of compound package lists, using any combination of
  :or/:any and :and/:all
    (after! (:or package-a package-b ...)  BODY...)
    (after! (:and package-a package-b ...) BODY...)
    (after! (:and package-a (:or package-b package-c) ...) BODY...)
  Without :or/:any/:and/:all, :and/:all are implied.

This is a wrapper around `eval-after-load' that:

1. Suppresses warnings for disabled packages at compile-time
2. Supports compound package statements (see below)
3. Prevents eager expansion pulling in autoloaded macros all at once"
  (declare (indent defun) (debug t))
  (if (symbolp package)
      (list (if (or (not (bound-and-true-p byte-compile-current-file))
                    (require package nil 'noerror))
                #'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))))
            ((memq p '(:and :all))
             (dolist (next (cdr package))
               (setq body `((after! ,next ,@body))))
             (car body))))))

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))))

xah/open-in-external-app

(defun xah/open-in-external-app (&optional file)
  "Open FILE or dired marked FILE in external app.
The app is chosen from the users OS preference."
  (interactive)
  (let ((file-list (if file
                       (list file)
                     (if (equal major-mode "dired-mode")
                         (dired-get-marked-files)
                       (list (buffer-file-name)))))
        (do-it-p   (if (<= (length file-list) 5)
                       t
                     (y-or-n-p "Open more than 5 files? "))))
    (when do-it-p
      (mapc (lambda (file-path)
              (let ((process-connection-type nil))
                (start-process "" nil "xdg-open" file-path)))
            file-list))))

xah/dired-sort

(defun xah/dired-sort ()
  "Sort dired dir listing in different ways.
Prompt for a choice."
  (interactive)
  (let (sort-by arg)
    (setq sort-by (completing-read "Sort by:" '("name" "size" "date" "extension")))
    (pcase sort-by
      ("name" (setq arg "-ahl --group-directories-first"))
      ("date" (setq arg "-ahl -t --group-directories-first"))
      ("size" (setq arg "-ahl -S --group-directories-first"))
      ("extension" (setq arg "ahlD -X --group-directories-first"))
      (otherwise (error "Dired-sort: unknown option %s" otherwise)))
    (dired-sort-other arg)))

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*"))

Org Functions

Emphasize text

/ <c> <c>
Emphasis Character Character code
Bold * 42
Italic / 47
Code ~ 126
(defun org-mode-emphasize-bold ()
  "Emphasize as bold the current region.

See also `org-emphasize'."
  (interactive)
  (org-emphasize 42))

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 ()
  (interactive)
  (split-window-right)
  (windmove-right)
  (when (and (boundp 'golden-ratio-mode)
             (symbol-value golden-ratio-mode))
    (golden-ratio)))

(defun split-window-below-and-focus ()
  (interactive)
  (split-window-below)
  (windmove-down)
  (when (and (boundp 'golden-ratio-mode)
             (symbol-value golden-ratio-mode))
    (golden-ratio)))

phundrak/toggle-org-src-window-split

(defun phundrak/toggle-org-src-window-split ()
  "This function allows the user to toggle the behavior of
`org-edit-src-code'. If the variable `org-src-window-setup' has
the value `split-window-right', then it will be changed to
`split-window-below'. Otherwise, it will be set back to
`split-window-right'"
  (interactive)
  (if (equal org-src-window-setup 'split-window-right)
      (setq org-src-window-setup 'split-window-below)
    (setq org-src-window-setup 'split-window-right))
  (message "Org-src buffers will now split %s"
           (if (equal org-src-window-setup 'split-window-right)
               "vertically"
             "horizontally")))

Package Management

Repositories

By default, only GNUs repositories are available to the package managers of Emacs. I also want to use Melpa and org-modes repository, so lets 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 FSFs 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.

(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/")))

Straight

For my package management, I prefer to use straight (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.

(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))

(package-initialize)
(unless package-archive-contents
  (package-refresh-contents))

;; Initialize use-package on non-Linux platforms
(unless (package-installed-p 'use-package)
  (package-install 'use-package))

(require 'use-package)
(setq use-package-always-ensure t)

Keybinding Management

Which-key

(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, my keybinds that are not bound to a specific mode will be prefixed with SPC, but when I want to get more specific in terms of mode, I'll prefix them with a comma (Ive taken this habit from Spacemacs).

(use-package general
  :defer t
  :straight (:build t)
  :init
  (general-auto-unbind-keys))
(mapconcat (lambda (line)
             (let* ((key      (car line))
                    (function (cadr line))
                    (function (if (or (string= "nil" function)
                                      (string= ""    function))
                                  ":ignore"
                                function))
                    (comment  (caddr line)))
               (format "\"%s\" %s" key
                       (if (string= "" comment)
                           (if (string= "nil" function)
                               "nil"
                            (concat "#'" function))
                        (format "'(%s :which-key \"%s\")"
                                function
                                (if (string= "" function)
                                    "nil"
                                  comment))))))
           table
           "\n")

  :straight (:build t)
  :init

Hydra

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))

Ivy

My main menu package is ivy which I use as much as possible Ive noticed helm can be slow, very slow in comparison to ivy so Ill 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
  :straight (:build t)
  :defer t
  :diminish
  :bind (("C-s" . swiper)
         :map ivy-minibuffer-map
         ("TAB" . ivy-alt-done)
         ("C-l" . ivy-alt-done)
         ("C-t" . ivy-next-line)
         ("C-s" . ivy-previous-line)
         :map ivy-switch-buffer-map
         ("C-t" . ivy-next-line)
         ("C-s" . ivy-previous-line)
         ("C-l" . ivy-done)
         ("C-d" . ivy-switch-buffer-kill)
         :map ivy-reverse-i-search-map
         ("C-t" . ivy-next-line)
         ("C-s" . ivy-previous-line)
         ("C-d" . ivy-reverse-i-search-kill))
  :config
  (ivy-mode 1)
  (setq ivy-wrap                        t
        ivy-height                      17
        ivy-sort-max-size               50000
        ivy-fixed-height-minibuffer     t
        ivy-read-action-functions       #'ivy-hydra-read-action
        ivy-read-action-format-function #'ivy-read-action-format-columns
        projectile-completion-system    'ivy
        ivy-on-del-error-function       #'ignore
        ivy-use-selectable-prompt       t))

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 Id 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)
  :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))))

Finally, lets make ivy richer:

(use-package ivy-rich
  :straight (:build t)
  :after ivy
  :init
  (ivy-rich-mode 1))

Counsel

(use-package counsel
  :straight (:build t)

         ("C-x b"   . counsel-ibuffer)
         ("C-x C-f" . counsel-find-file)
         :map minibuffer-local-map
         ("C-r" . 'counsel-minibuffer-history)))

Yasnippet

(use-package yasnippet
  :defer t
  :straight (:build t)
  :init
  (yas-global-mode)
  :hook ((prog-mode . yas-minor-mode)
         (text-mode . yas-minor-mode)))
(use-package yasnippet-snippets
  :defer t
  :after yasnippet
  :straight (:build t))
(use-package yatemplate
  :defer t
  :after yasnippet
  :straight (:build t))
(use-package ivy-yasnippet
  :defer t
  :after (ivy yasnippet)
  :straight (:build t))

Applications

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)
  :init
  (put 'docker-image-name 'safe-local-variable #'stringp)
  :mode "Dockerfile\\'")

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)
  :custom
  ((elfeed-search-filter "@6-months-ago")
   (elfeed-db-directory  (expand-file-name ".elfeed-db"
                                           user-emacs-directory))))

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.

(use-package elfeed-goodies
  :defer t
  :after elfeed
  :commands elfeed-goodies/setup
  :straight (:build t)
  :init
  (elfeed-goodies/setup)
  :general
  (:keymaps '(elfeed-show-mode-map elfeed-search-mode-map)
   :states  '(normal emacs)
   "SPC" nil
   "DEL" nil
   "s"   nil)
  (:keymaps 'elfeed-show-mode-map

   "tu" #'elfeed-search-untag-all-unread
   "tT" #'elfeed-search-tag-all
   "tU" #'elfeed-search-untag-all))

Last but not least, my Elfeed configuration is stored in an org file thanks to elfeed-org.

(use-package elfeed-org
  :defer t
  :after elfeed
  :straight (:build t)
  :init
  (elfeed-org)
  :config
  (setq rmh-elfeed-org-files '("~/org/elfeed.org")))

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 dont want it to include it a second time after org-msg already did.

(setq message-signature nil
      mail-signature    nil)
Mu4e

Mu4e is a very eye-pleasing email client for Emacs, built around mu and which works very well with mbsync (found in Archs 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 youll find my configuration for the mu4e package itself.

Quick sidenote: on ArchLinux, youll need to install either mu or mu-git from the AUR in order to use mu4e. I also have a .desktop file so I can open mu4e directly from my program picker. It uses the shell script emacsmail Ive written here.

Basic configuration

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

(setq smtpmail-smtp-server       "mail.phundrak.com"
      smtpmail-smtp-service      587
      smtpmail-stream-type       'starttls
      message-send-mail-function 'smtpmail-send-it)

We also need to inform it on where my emails are stored on my machine, and how to retrieve them.

(setq mu4e-get-mail-command "mbsync -a"
      mu4e-maildir          "~/Mail"
      mu4e-trash-folder     "/Trash"
      mu4e-refile-folder    "/Archive"
      mu4e-sent-folder      "/Sent"
      mu4e-drafts-folder    "/Drafts")

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 isnt 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)
  • the conlang mailing lists
  • and my inbox for any mail not caught by any of these filters

And all of them will have the requirement not to display any trashed email. Actually, all of my bookmarks will have this requirement, except for the bookmark dedicated to them as well as my sent emails. Ill 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).

(let ((regex "/.*up8\\.edu|.*univ-paris8.*/"))
  <<mu4e-bookmarks-from-copy-to-gen>>)
f:/.*up8\.edu|.*univ-paris8.*/ OR c:/.*up8\.edu|.*univ-paris8.*/ OR t:/.*up8\.edu|.*univ-paris8.*/

Next I need an inbox dedicated to the association Im 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.

(mapconcat (lambda (address)
             (mapconcat (lambda (flag)
                          (concat flag ":" address))
                        '("list" "t" "f")
                        " OR "))
           '("ateliers-emacs.framalistes.org" "ateliers-paris.emacs-doctor.com")
           " OR ")
list:ateliers-emacs.framalistes.org OR t:ateliers-emacs.framalistes.org OR f:ateliers-emacs.framalistes.org OR list:ateliers-paris.emacs-doctor.com OR t:ateliers-paris.emacs-doctor.com OR f:ateliers-paris.emacs-doctor.com

Another bookmark I wish to have is one dedicated to emails related to issues and PRs from Github.

(string-join '("list:/.*\\.github\\.com/"
               "to:/.*noreply\\.github\\.com/")
             " OR ")
list:/.*\.github\.com/ OR to:/.*noreply\.github\.com/

When it comes to the conlang mailing list, lets not match anything from or to them. Ill also include the auxlang mailing list Im not subscribed anymore, but itll keep my inbox clean.

(mapconcat (lambda (address)
             (mapconcat (lambda (flag)
                          (concat flag ":" address))
                        '("f" "t" "list")
                        " OR "))
           '("CONLANG@LISTSERV.BROWN.EDU" "AUXLANG@LISTSERV.BROWN.EDU")
           " OR ")
f:CONLANG@LISTSERV.BROWN.EDU OR t:CONLANG@LISTSERV.BROWN.EDU OR list:CONLANG@LISTSERV.BROWN.EDU OR f:AUXLANG@LISTSERV.BROWN.EDU OR t:AUXLANG@LISTSERV.BROWN.EDU OR list:AUXLANG@LISTSERV.BROWN.EDU

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:

(string-join `("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, lets describe my main inbox:

(string-join (cons
              "<<mu4e-bookmarks-default-filter()>>"
              `(
                ,(format "(%s)"
                         <<mu4e-bookmarks-filter-conlang-list>>)
                ,(format "(%s)" "<<mu4e-bookmarks-filter-asso()>>")
                ,(format "(%s)"
                         <<mu4e-bookmarks-filter-emacs-list>>)
                ,(format "(%s)"
                         <<mu4e-bookmarks-filter-uni>>)))
             " AND NOT ")
NOT flag:trashed AND (maildir:/Inbox OR maildir:/Junk) AND NOT (f:CONLANG@LISTSERV.BROWN.EDU OR t:CONLANG@LISTSERV.BROWN.EDU OR list:CONLANG@LISTSERV.BROWN.EDU OR f:AUXLANG@LISTSERV.BROWN.EDU OR t:AUXLANG@LISTSERV.BROWN.EDU OR list:AUXLANG@LISTSERV.BROWN.EDU) AND NOT (f:/.*supran.fr/ OR c:/.*supran.fr/ OR t:/.*supran.fr/) AND NOT (list:ateliers-emacs.framalistes.org OR t:ateliers-emacs.framalistes.org OR f:ateliers-emacs.framalistes.org OR list:ateliers-paris.emacs-doctor.com OR t:ateliers-paris.emacs-doctor.com OR f:ateliers-paris.emacs-doctor.com) AND NOT (f:/.*up8\.edu|.*univ-paris8.*/ OR c:/.*up8\.edu|.*univ-paris8.*/ OR t:/.*up8\.edu|.*univ-paris8.*/)

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>>))

Dealing with spammers

Im 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 dont 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 Ill 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, its worth your time! And in case the Twitter thread disappear in the future, here is a backup.

Getting Fancy

Im not a huge fan of mu4es default icons marking my emails, so Ill 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))

Lets 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))
    (message "Window width: %d\tthreshold: %d\nSplit: %S"
             width
             threshold
             mu4e-split-view)))

(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. Lets undefine some of these:

(general-define-key
 :keymaps '(mu4e-headers-mode-map mu4e-view-mode-map)
 "SPC" nil
 "s"   nil)
(general-define-key
 :states 'normal
 :keymaps '(mu4e-headers-mode-map mu4e-view-mode-map)
 "SPC" nil
 "s"   nil
 ","   nil)
(general-define-key
 :keymaps 'mu4e-view-mode-map
 "SPC" nil
 "S"   nil
 "r"   nil
 "c"   nil)
(general-define-key
 :keymaps 'mu4e-view-mode-map
 :states 'normal
 "SPC" nil
 "S"   nil
 "r"   nil
 "c"   nil
 "gu"  nil)

Now, lets define some keybindings for mu4es 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
a nil attachments
a& mu4e-view-pipe-attachment
aa mu4e-view-attachment-action
ao mu4e-view-open-attachment
aO mu4e-view-open-attachment-with
c nil compose
cc mu4e-compose-new
ce mu4e-compose-edit
cf mu4e-compose-forward
cr mu4e-compose-reply
cR mu4e-compose-resend
g nil go to
gu mu4e-view-go-to-url
gX mu4e-view-fetch-url
l mu4e-show-log
m nil mark
md mu4e-view-mark-for-trash
mD mu4e-view-mark-for-delete
mm mu4e-view-mark-for-move
mr mu4e-view-mark-for-refile
mR mu4e-view-mark-for-read
mu mu4e-view-mark-for-unread
mU mu4e-view-mark-for-unmark
t mu4e-view-mark-thread mark thread
T nil toggle
Tc mu4e-view-toggle-hide-cited
Th mu4e-view-toggle-html
n mu4e-view-headers-next
N mu4e-view-headers-next-unread
p mu4e-view-headers-prev
P mu4e-view-headers-prev-unread
(general-define-key
   :states 'normal
   :keymaps 'mu4e-view-mode-map
   :prefix ","
   <<general-keybindings-gen(table=mu4e-keybindings-view-tbl)>>)

Ill also declare two keybinds for mu4es headers mode.

(general-define-key
   :states 'normal
   :keymaps 'mu4e-headers-mode-map
   :prefix ","
   "t" '(mu4e-view-mark-thread :which-key "mark thread")
   "s" 'swiper)

I will also redefine without a leader key ctsr in order to be able to move freely (remember, bépo layout for me).

(general-define-key
 :keymaps 'mu4e-headers-mode-map
 :states 'normal
 "c" #'evil-backward-char
 "t" #'evil-next-line
 "s" #'evil-previous-line
 "r" #'evil-forward-char)

Finally, lets 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.

Key Function Description
, message-send-and-exit
c message-send-and-exit
a message-kill-buffer
k message-kill-buffer
s message-dont-send
f mml-attach-file)
(general-define-key
 :states 'normal
 :keymaps 'message-mode-map
 :prefix ","
 <<general-keybindings-gen(table=mu4e-keybindings-message-tbl)>>
Composing messages
(use-package org-msg
  :after (org mu4e)
  :straight (:build t)
  :hook ((mu4e-compose-pre . org-msg-mode))
  :general (:keymaps 'org-msg-edit-mode-map
            :prefix ","
            :states 'normal
            "," #'message-send-and-exit
            "c" #'message-send-and-exit

  (defun my/org-msg-signature-convert (orig-fun &rest args)

        (setf (alist-get 'signature res)

      res))
  (advice-add 'org-msg-composition-parameters
              :around 'my/org-msg-signature-convert)
  (add-hook 'mu4e-headers-mode (lambda () (toggle-truncate-lines -1)))
  (setq org-msg-startup              "inlineimages"
        org-msg-default-alternatives '((new           . (text html))

                                                (insert-file-contents mail-signature-file)
                                                (buffer-string)))))))
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, Ill use Emacs default notification system, and Ill activate the modeline notification.

(use-package mu4e-alert
  :straight (:build t)
  :defer t
  :init

EMMS and Media

EMMS, also known as the Emacs MultiMedia System, allows the user to interact through Emacs with multimedia elements such as music and videos. My main use for it will be for music with MPD (see its configuration here).

Nov

Nov is a major-mode for reading EPUB files within Emacs. Since I have it, I dont need any other Epub reader on my computer! Plus this one is customizable and programmable, why would I use any other EPUB reader?

(use-package nov

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 Zathuras recolor feature which kind of enables a dark mode for PDFs.

(use-package pdf-tools

One thing pdf-tools doesnt handle is restoring the PDF to the last point it was visited — in other words, open the PDF where I last left it.

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 doesnt happen with Magit, its 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!

(use-package magit
  :straight (:build t)
  :defer t
  :custom
  (magit-display-buffer-function #'magit-display-buffer-same-window-except-diff-v1)

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.

(use-package magit-todos
  :straight (:build t)
  :after magit
  :config
  (setq magit-todos-ignore-case t))

Finally, it is also possible to use Gitflows framework with Magit with magit-gitflow:

(use-package magit-gitflow
  :defer t
  :after magit
  :straight (magit-gitflow :build t
                           :type git
                           :host github

Shell-pop allows the user to easily call for a new shell in a pop-up buffer.

        wttrin-use-metric t))

Editing

First, Ill define some keybindings for easily inserting pairs when editing text.

(general-define-key
 :states 'visual
 "M-["  #'insert-pair
 "M-{"  #'insert-pair
 "M-<"  #'insert-pair
 "M-'"  #'insert-pair
 "M-`"  #'insert-pair
 "M-\"" #'insert-pair)

Atomic Chrome

Why write in your browser when you could write with Emacs? Despite its name, this package isnt only geared towards Chrome/Chromium-based browsers but also towards Firefox since its 2.0 version. I find it a bit unfortunate Chromes name stuck in the packages name though.

(use-package atomic-chrome
  :straight (:build t)
  :init
  (atomic-chrome-start-server))

Evil Nerd Commenter

Emacs default commenting system is nice, but I dont find it smart enough for me.

(use-package evil-nerd-commenter
  :after evil
  :straight (:build t))

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.

(use-package iedit
  :defer t
  :straight (:build t)
  :general
  (:states 'normal
   :prefix "SPC"
   "r" '(nil :which-key "refactor")
   "ri" #'iedit-mode))

Since Im using evil, Ill also use a compatibility package that adds states for iedit.

(use-package evil-iedit-state
  :after iedit
  :defer t
  :straight (:build t)
  :commands (evil-iedit-state evil-iedit-state/iedit-mode)
  :init
  (setq iedit-curent-symbol-default     t
        iedit-only-at-symbol-boundaries t
        iedit-toggle-key-default        nil)
  :general
  (:keymaps 'evil-iedit-state-map
   "SPC" nil))

Parinfer

Dont 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.

(use-package parinfer-rust-mode
  :defer t
  :straight (:build t)
  :diminish parinfer-rust-mode
  :hook emacs-lisp-mode common-lisp-mode scheme-mode
  :init
  (setq parinfer-rust-auto-download     t
        parinfer-rust-library-directory (concat user-emacs-directory
                                                "parinfer-rust/")))

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.

(use-package smartparens
  :defer t
  :straight (:build t)
  :hook (prog-mode . smartparens-mode))

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!

(use-package string-edit
  :defer t
  :straight (:build t))

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.

(use-package writeroom-mode
  :defer t
  :straight (:build t)
  :config
  (setq writeroom-width             100
        writeroom-fullscreen-effect nil
        writeroom-maximize-window   nil
        writeroom-mode-line         t))

Emacs built-ins

Dired

Dired is Emacs built-in file manager. Its 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 its the same thing.

However, the only thing I lack still is thumbnails. In any case, I need still to make some tweaks in order to make it usable for me.

(use-package dired
  :straight (:type built-in)
  :defer t
  :hook (dired-mode . turn-on-gnus-dired-mode)
  :general
  (:keymaps 'dired-mode-map
   "SPC" nil)
  (:keymaps 'dired-mode-map
   :states 'normal
   "SPC" nil
   "(" #'dired-hide-details-mode
   "n" #'evil-next-line
   "p" #'evil-previous-line)
  :config
  (setq dired-dwim-target       t
        dired-recursive-copies  t
        dired-recursive-deletes t
        dired-listing-switches  "-ahl --group-directories-first"))

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

Dired-x stands for “dired extra” which provides a couple more features that are for some reason not included in dired yet.

(use-package dired-x
  :straight (:type built-in)
  :after dired
  :commands (dired-jump dired-jump-other-window dired-omit-mode)
  :general
  (:keymaps 'dired-mode-map
   :states 'normal
   "«" #'dired-omit-mode))

dired-du provides the user with the option to be able to see the size of directories as they are, rather than just the size of their inode. However, I will not enable it by default as it can take some time to get the actual size of a directory.

(use-package dired-du
  :after dired
  :straight (:build t)
  :general
  (:keymaps 'dired-mode-map
   :states 'normal
   "»" #'dired-du-mode))

This package on the other hand provides Git information to the user in the current dired buffer in a similar way to how Github and Gitea display the latest commit message and its age about a file in the file tree. And by default, I want dired-git-info to hide file details.

(use-package dired-git-info
  :after (dired)
  :straight (:build t)
  :hook (dired-after-reading . dired-git-info-auto-enable)
  :general
  (:keymaps 'dired-mode-map
   :states 'normal
   ")" #'dired-git-info-mode)
  :config
  (setq dgi-auto-hide-details-p t))

Diredfl makes dired colorful, and much more readable in my opinion.

(use-package diredfl
  :after (dired all-the-icons)
  :straight (:build t)
  :init
  (diredfl-global-mode 1))

And lets add some fancy icons in dired!

(use-package all-the-icons-dired
  :after (all-the-icons)
  :straight (:build t)
  :defer t
  :hook (dired-mode . all-the-icons-dired-mode))
(use-package image-dired+
  :after (image-dired)
  :straight (:build t)
  :init (image-diredx-adjust-mode 1))

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, lets redefine some keybinds for this mode. Ill also define a general keybind in order to re-run my programs from other buffers than the compilation-mode buffer.

(after! compile
  (general-define-key
   :keymaps 'compilation-mode-map
   "g" nil
   "r" #'recompile
   "h" nil))

(general-define-key
 :states 'normal
 :prefix "SPC"
 "R" #'recompile)

I also want to follow the output of the compilation buffer, as well as enable some syntax highlighting, so lets do this.

(after! compile
  (setq compilation-scroll-output t))

(require 'ansi-color)

(defun colorize-compilation-buffer ()
  (let ((inhibit-read-only t))
    (ansi-color-apply-on-region (point-min) (point-max))))

(add-hook 'compilation-mode-hook #'colorize-compilation-buffer)

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.

(use-package eshell
  :defer t
  :straight (:type built-in :build t)
  :general
  (:keymaps 'eshell-mode-map
   :states 'normal
   "c" #'evil-backward-char
   "t" #'evil-next-line
   "s" #'evil-previous-line
   "r" #'evil-forward-char)
  (:keymaps 'eshell-mode-map
   :states 'insert
   "C-a" #'eshell-bol
   "C-e" #'end-of-line)
  :config
  <<eshell-alias-file>>
  <<eshell-concat-shell-command>>
  <<eshell-alias-open>>
  <<eshell-alias-buffers>>
  <<eshell-alias-emacs>>
  <<eshell-alias-mkcd>>)
Aliases

First, lets declare our list of “dumb” aliases well use in Eshell. You can find them here.

(setq eshell-aliases-file (expand-file-name "eshell-aliases" user-emacs-directory))

A couple of other aliases will be defined through custom Elisp functions, but first Ill 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."
  (string-join command " "))

Ill 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)

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. Ill 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: Im already inside Emacs and I have all its power available instantly. So, lets 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, Ill 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 dont, similarly to the -p option passed to mkdir.

(defun eshell/mkcd (dir)
  "Create the directory DIR and move there.
If the directory DIR doesnt exist, create it and its parents
if needed, then move there."
  (mkdir dir t)
  (cd dir))
Autosuggestion

I really like fishs autosuggestion feature, so lets 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 Im 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. Lets 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 bashs and zshs 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 havent found anything that does that the way I like it, so Ive written a package!

(use-package eshell-info-banner
  :after (eshell)
  :defer t
  :straight (eshell-info-banner :build t
                                :type git
                                :host github
                                :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
  :load-path "~/fromGIT/emacs-packages/powerline-eshell.el/"
  :after eshell)

Eww

Since Emacs 29, it is possible to automatically rename eww buffers to a more human-readable name, see Prots blog post on the matter.

(use-package eww
  :defer t
  :straight (:type built-in)
  :config
  (setq eww-auto-rename-buffer 'title))

Info

Lets define some more intuitive keybinds for info-mode.

(use-package info
  :defer t
  :straight (info :type built-in :build t)
  :general
  (:keymaps 'Info-mode-map
   :states '(normal emacs)
   "SPC" nil
   ","   nil)
  (:keymaps 'Info-mode-map
   :states 'normal
   "c" #'Info-prev
   "t" #'evil-scroll-down
   "s" #'evil-scroll-up
   "r" #'Info-next)
  (:keymaps 'Info-mode-map
   :states 'normal
   :prefix ","
   "?" #'Info-toc
   "b" #'Info-history-back
   "f" #'Info-history-forward
   "m" #'Info-menu
   "t" #'Info-top-node
   "u" #'Info-up))

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.

(require 'tramp)
(use-package tramp
  :straight (tramp :type built-in :build t)
  :init
  <<tramp-add-yadm>>)
Yadm

yadm is a git wrapper made to easily manage your dotfiles. It has loads of features I dont use (the main one I like but dont use is its Jinja-like host and OS-aware syntax), but unfortunately Magit doesnt play nice with it. Tramp to the rescue, and this page explains how! Lets 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"))))

Ill also create a fuction for connecting to this new Tramp protocol:

(defun my/yadm ()
  "Manage my dotfiles through TRAMP."
  (interactive)
  (magit-status "/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 lets redefine them, and lets also rebind SPC to p since it would conflict with my main general prefix.

(use-package bufler
  :straight (bufler :build t
                    :files (:defaults (:exclude "helm-bufler.el")))
  :defer t
  :general
  (:keymaps 'bufler-list-mode-map
   :states  'normal
   "?"   #'hydra:bufler/body
   "g"   #'bufler
   "f"   #'bufler-list-group-frame
   "F"   #'bufler-list-group-make-frame
   "N"   #'bufler-list-buffer-name-workspace
   "k"   #'bufler-list-buffer-kill
   "p"   #'bufler-list-buffer-peek
   "s"   #'bufler-list-buffer-save
   "RET" #'bufler-list-buffer-switch))

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
(use-package helpful
  :straight (:build t)
  :after (counsel ivy)
  :custom
  (counsel-describe-function-function #'helpfull-callable)
  (counsel-describe-variable-function #'helpfull-variable)
  :bind
  ([remap describe-function] . counsel-describe-function)
  ([remap describe-command]  . helpful-command)
  ([remap describe-variable] . counsel-describe-variable)
  ([remap describe-key]      . helpful-key))

Org-mode

Since recently, in order to make org-cite compile properly, we need the citeproc package, a citation processor.

(use-package citeproc
  :after (org)
  :defer t
  :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!

(use-package org
  :straight t
  :defer t
  :commands (orgtbl-mode)
  :hook ((org-mode . visual-line-mode)
         (org-mode . org-num-mode))

The main feature from evil-org that I love is how easy it is to modify some keybindings for keyboards layouts that do not have hjkl, such as the bépo layout (or Dvorak or Colemak if you are into that). But it also adds a ton of default keybindings which are just much more comfortable than the default ones you get with evil and org naked.

(use-package evil-org
  :straight (:build t)
  :after (org)
  :hook (org-mode . evil-org-mode)
  :config
  (setq-default evil-org-movement-bindings
                '((up    . "s")
                  (down  . "t")
                  (left  . "c")
                  (right . "r")))
  (evil-org-set-key-theme '(textobjects navigation calendar additional shift operators))
  (require 'evil-org-agenda)
  (evil-org-agenda-set-keys))

This package is a small package Ive written that helps me when writing conlanging documents, with features such as creating syntax trees, converting translitterated text to its native script, etc…

(use-package conlanging
  :straight (conlanging :build t
                        :type git
                        :repo "https://labs.phundrak.com/phundrak/conlanging.el")
  :after org
  :defer t)

Since very recently, the contrib/lisp/ directory of org moved out of the main repository to this repository. On the other hand, contrib/scripts/ moved to the worg repository, but I dont need it. The main reason I want org-contrib is due to ox-extra that allow the usage of the :ignore: tag in org.

(use-package org-contrib
  :after (org)
  :defer t
  :straight (:build t)
  :init
  (require 'ox-extra)
  (ox-extras-activate '(latex-header-blocks ignore-headlines)))

Agenda

(setq-default org-agenda-files (list "~/org/agenda" "~/org/notes.org"))

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.

(use-package toc-org
  :after (org markdown-mode)
  :straight (:build t)
  :init
  (add-to-list 'org-tag-alist '("TOC" . ?T))
  :hook (org-mode . toc-org-enable)
  :hook (markdown-mode . toc-org-enable))

electric-mode also bothers me a lot when editing org files, so lets deactivate it:

(add-hook 'org-mode-hook (lambda ()
                           (interactive)
                           (electric-indent-local-mode -1)))

As explained in my blog post, org-mode is terrible with coming up with meaningful IDs for its headings. I actually wrote a package for this!

(use-package org-unique-id
  :straight (org-unique-id :build t
                           :type git
                           :host github
                           :repo "Phundrak/org-unique-id")
  :defer t
  :after org
  :init
  (add-hook 'org-mode-hook
     (lambda ()
       (add-hook 'before-save-hook
                 (lambda ()
                   (when (and (eq major-mode       'org-mode)
                              (eq buffer-read-only nil))
                     (org-unique-id)))))))

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:

(use-package ob-latex-as-png
  :after (org)
  :straight (:build t)
  :defer t)
(use-package ob-restclient
  :straight (:build t)
  :defer t)

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
dot
emacs-lisp
gnuplot
latex
makefile
plantuml
python
sass
shell
'((C . t)
  (dot . t)
  (emacs-lisp . t)
  (gnuplot . t)
  (latex . t)
  (latex-as-png . t)
  (makefile . t)
  (plantuml . t)
  (python . t)
  (restclient . t)
  (sass . t)
  (shell . t))

The corresponding code is as follows:

(org-babel-do-load-languages
 'org-babel-load-languages
 <<org-babel-languages-gen()>>)

File export

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, lets disable it:

(setq org-use-sub-superscripts (quote {}))
Epub

A backend for exporting files through org I like is ox-epub which, as you can guess, exports org files to the Epub format.

(use-package ox-epub
  :after (org ox)
  :straight (:build t))
HTML

For Reveal.JS exports, I need to set where to find the framework by default:

(setq org-re-reveal-root "https://cdn.jsdelivr.net/npm/reveal.js")

On HTML exports, Org-mode tries to include a validation link for the exported HTML. Lets disable that since I never use it.

(setq org-html-validation-link nil)
;; (use-package htmlize
;;   :defer t
;;   :straight (:build t))

This package allows for live-previewing the HTML export of an org buffer in an XWidget Webkit browser window. But when testing it, its not great for large org files, I should keep its usage for smaller org files.

(use-package preview-org-html-mode
  :defer t
  :after (org)
  :straight (preview-org-html-mode :build t
                                   :type git
                                   :host github
                                   :repo "jakebox/preview-org-html-mode")
  :general
  (:keymaps '(org-mode-map)
   :states 'normal
   :prefix ","
   "P"  '(:ignore :which-key "preview")
   "Ph" #'preview-org-html-mode
   "Pr" #'preview-org-html-refresh
   "Pp" #'preview-org-html-pop-window-to-frame)
  :config
  (setq preview-org-html-refresh-configuration 'save))
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:

(setq org-latex-compiler "xelatex")

I also want to get by default minted for LaTeX listings so I can have syntax highlights:

(setq org-latex-listings 'minted)

The default packages break my LaTeX exports: for some reasons, images are not loaded and exported in PDFs, so I needed to redifine the default packages excluding the one that broke my exports; namely, I need to remove inputenc, fontenc and grffile. I also added some default packages:

  • minted for syntax highlighting
  • cleveref for better references to various elements.
  • svg for inserting SVG files in PDF outputs
  • booktabs for nicer tables
  • and tabularx for tabulars with adjustable columns
(dolist (package '(("AUTO" "inputenc" t ("pdflatex"))
                   ("T1"   "fontenc"  t ("pdflatex"))
                   (""     "grffile"  t)))
  (delete package org-latex-default-packages-alist))

(dolist (package '((""           "minted")
                   ("capitalize" "cleveref")
                   (""           "svg")
                   (""           "booktabs")
                   (""           "tabularx")))
  (add-to-list 'org-latex-default-packages-alist package t))

(setq org-latex-reference-command "\\cref{%s}")

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}")

And Minted should be default break lines if a line is too long:

(setq org-latex-minted-options '(("breaklines")
                                 ("tabsize" "2")
                                 ("frame" "single")
                                 ("autogobble")))

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. Dont forget to also run bibtex!

(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"))

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))
Markdown

Theres not really any unified Markdown specification, meaning everyone can pretty much do whatever they want with the syntax and still call it Markdown. Great… But something I appreciate is Github supports some extra HTML to make our files extra spicy! And lucky me, theres a package for exporting my org files to Github-flavored Markdown!

(use-package ox-gfm
  :after (ox org)
  :straight (:build t))
SSH Config

Yet another exporter I enjoy is ox-ssh with which I manage my $HOME/.ssh/config file. You wont find my org file for managing my servers on my repos though.

(use-package ox-ssh
  :after (ox org)
  :straight (:build t))

Keybindings

Be prepared, I have a lot of keybindings for org-mode! They are all prefixed with a comma , in normal mode.

Key chord Function Description
RET org-ctrl-c-ret
* org-ctrl-c-star
, org-ctrl-c-ctrl-c
' org-edit-special
- org-ctrl-c-minus
a org-agenda
c org-capture
e org-export-dispatch
l org-store-link
p org-priority
r org-reload

I then have a couple of babel-related functions.

Key chord Function Description
b nil babel
b. org-babel-transient/body
bb org-babel-execute-buffer
bc org-babel-check-src-block
bC org-babel-tangle-clean
be org-babel-execute-maybe
bf org-babel-tangle-file
bn org-babel-next-src-block
bo org-babel-open-src-block-result
bp org-babel-previous-src-block
br org-babel-remove-result-one-or-many
bR org-babel-goto-named-result
bt org-babel-tangle
bi org-babel-view-src-block-info

The org-babel-transient hydra allows me to quickly navigate between code blocks and interact with them. This code block was inspired by one you can find in Spacemacs.

(defhydra org-babel-transient ()

We next have keybindings related to org-modes agenda capabilities. We can schedule a todo header for some dates, or set a deadline.

Key chord Function Description
d nil dates
dd org-deadline
ds org-schedule
dt org-time-stamp
dT org-time-stamp-inactive

Lets now define some keybinds for inserting stuff in our org buffer:

Key chord Function Description
i nil insert
ib org-insert-structure-template
id org-insert-drawer
ie org-set-effort
if org-footnote-new
ih org-insert-heading
ii org-insert-item
il org-insert-link
in org-add-note
ip org-set-property
is org-insert-subheading
it org-set-tags-command

There isnt a lot of stuff I can jump to yet, but theres 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
t nil tables
tc org-table-move-column-left
tt org-table-move-row-down
ts org-table-move-row-up
tr org-table-move-column-right
ta org-table-align
te org-table-eval-formula
tf org-table-field-info
th org-table-convert
tl org-table-recalculate
tp org-plot/gnuplot
tS org-table-sort-lines
tw org-table-wrap-region
tx org-table-shrink
tN org-table-create-with-table.el
td nil delete
tdc org-table-delete-column
tdr org-table-kill-row
ti nil insert
tic org-table-insert-column
tih org-table-insert-hline
tir org-table-insert-row
tiH org-table-hline-and-move
tt nil toggle
ttf org-table-toggle-formula-debugger
tto org-table-toggle-coordinate-overlays

Finally, lets make enabling and disabling stuff accessible:

Key chord Function Description
T nil toggle
Tc org-toggle-checkbox
Ti org-toggle-inline-images
Tl org-latex-preview
Tn org-num-mode
Ts phundrak/toggle-org-src-window-split
Tt org-show-todo-tree
TT org-todo

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-org"
 :base-directory ,phundrak//projects-config-source
 :base-extension "org"
 :publishing-directory ,phundrak//projects-config-target
 :recursive ,phundrak//projects-config-recursive
 :language ,phundrak//projects-config-language
 :publishing-function org-html-publish-to-html
 :headline-levels 5
 :auto-sitemap t
 :auto-preamble t)

We also have the component for all the static files needed to run the website (mostly images tbh).

("config-website-static"
 :base-directory ,phundrak//projects-config-source
 :base-extension "png\\|jpg\\|gif\\|webp\\|svg\\|jpeg\\|ttf\\|woff\\|txt\\|epub\\|md"
 :publishing-directory ,phundrak//projects-config-target
 :recursive ,phundrak//projects-config-recursive
 :language ,phundrak//projects-config-language
 :publishing-function org-publish-attachment)

The project is then defined like so:

("config-website"
 :components ("config-website-org"
              "config-website-static"))
Linguistics website

My linguistics website is made out of three projects. As for the previous project, lets declare the common values for these.

(defvar phundrak//projects-conlanging-target
  "/ssh:Tilo:~/www/phundrak.com/langue/"
  "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
  "fr"
  "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.

("langue-phundrak-com-org"
 :base-directory ,phundrak//projects-conlanging-source
 :base-extension "org"
 :exclude "\\./\\(CONTRIB\\|README\\|head\\|temp\\|svg-ink\\).*"
 :publishing-directory ,phundrak//projects-conlanging-target
 :recursive ,phundrak//projects-conlanging-recursive
 :language ,phundrak//projects-conlanging-language
 :publishing-function org-html-publish-to-html
 :headline-levels 5
 :auto-sitemap t
 :auto-preamble t)

We also have the component for the LaTeX and PDF part of the website:

("langue-phundrak-com-pdf"
 :base-directory ,phundrak//projects-conlanging-source
 :base-extension "org"
 :exclude "\\./\\(CONTRIB\\|README\\|index\\|head\\|temp\\|svg-ink\\).*"
 :publishing-directory ,phundrak//projects-conlanging-target
 :recursive ,phundrak//projects-conlanging-recursive
 :language ,phundrak//projects-conlanging-language
 :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:

("langue-phundrak-com-static"
 :base-directory ,phundrak//projects-conlanging-source
 :base-extension "png\\|jpg\\|gif\\|webp\\|svg\\|jpeg\\|ttf\\|woff\\|txt\\|epub"
 :publishing-directory ,phundrak//projects-conlanging-target
 :recursive ,phundrak//projects-conlanging-recursive
 :language ,phundrak//projects-conlanging-language
 :publishing-function org-publish-attachment)

The project is then defined like so:

("langue-phundrak-com"
 :components ("langue-phundrak-com-org"
              "langue-phundrak-com-static"
              "langue-phundrak-com-pdf"))

Org-present

org-present allows its user to create presentations through org-mode, which is really nice! However, most of my configuration will be stolen from Daviwils with minor changes.

(defun my/org-present-prepare-slide ()
  (org-overview)
  (org-show-entry)
  (org-show-children)
  (org-present-hide-cursor))

(defun my/org-present-init ()

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!

(use-package mixed-pitch
  :after org
  :straight (:build t)
  :hook
  (org-mode           . mixed-pitch-mode)
  (emms-browser-mode  . mixed-pitch-mode)
  (emms-playlist-mode . mixed-pitch-mode)
  :config
  (add-hook 'org-agenda-mode-hook (lambda () (mixed-pitch-mode -1))))

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

(use-package org-pretty-table
  :defer t
  :after org
  :straight (org-pretty-table :type git
                              :host github
                              :repo "Fuco1/org-pretty-table"
                              :build t)
  :hook (org-mode . org-pretty-table-mode)
  :commands (org-pretty-table-mode global-org-pretty-table-mode))

I have an issue with org-modes 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!

(use-package org-appear
  :after org
  :straight (:build t)
  :hook (org-mode . org-appear-mode)
  :config
  (setq org-appear-autoemphasis   t
        org-hide-emphasis-markers t
        org-appear-autolinks      t
        org-appear-autoentities   t
        org-appear-autosubmarkers t)
  (run-at-time nil nil #'org-appear--set-elements))

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

(use-package org-fragtog
  :defer t
  :after org
  :straight (:build t)
  :hook (org-mode . org-fragtog-mode))

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!

(use-package org-superstar
  :after org
  :straight (:build t)
  :hook (org-mode . org-superstar-mode)
  :config
  (setq org-superstar-leading-bullet   ?\s
        org-superstar-leading-fallback ?\s
        org-hide-leading-stars         nil
        org-superstar-todo-bullet-alist
        '(("TODO" . 9744)
          ("[ ]"  . 9744)
          ("DONE" . 9745)
          ("[X]"  . 9745))))

org-fancy-priorities change the priority of an org element such such as #A to anything user-defined. Lets make this anything all-the-icons icons!

(use-package org-fancy-priorities
  :after (org all-the-icons)
  :straight (:build t)
  :hook (org-mode        . org-fancy-priorities-mode)
  :hook (org-agenda-mode . org-fancy-priorities-mode)
  :config
  (setq org-fancy-priorities-list `(,(all-the-icons-faicon "flag"     :height 1.1 :v-adjust 0.0)
                                    ,(all-the-icons-faicon "arrow-up" :height 1.1 :v-adjust 0.0)
                                    ,(all-the-icons-faicon "square"   :height 1.1 :v-adjust 0.0))))

Org Outline Tree is a better way of managing my org files outline.

DSLs

DSLs, or Domain Specific Languages, are languages dedicated to some very tasks, such as configuration languages or non-general programming such as SQL.

Caddy

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 doesnt support the syntax of Caddy files natively, so lets install caddyfile-mode:

(use-package caddyfile-mode
  :defer t
  :straight (:build t)
  :mode (("Caddyfile\\'" . caddyfile-mode)
         ("caddy\\.conf\\'" . caddyfile-mode)))
CMake

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 doesnt have a major mode available by default, so lets provide one.

(use-package cmake-mode
  :defer t
  :straight (:build t))

Lets enable first some autocompletion for it.

(use-package company-cmake
  :straight (company-cmake :build t
                           :type git
                           :host github
                           :repo "purcell/company-cmake")
  :after cmake-mode
  :defer t)

And lets also enable a more advanced CMake fontlock.

(use-package cmake-font-lock
  :defer t
  :after cmake-mode
  :straight (:build t))

And finally, lets enable some Eldoc integration for CMake.

(use-package eldoc-cmake
  :straight (:build t)
  :defer t
  :after cmake-mode)
Gnuplot

This package is a front-end and major mode for the programming language Gnuplot. Lets make some beautiful graphs, shall we?

(use-package gnuplot
  :straight (:build t)
  :defer t)
Graphviz

Graphviz, often known with dot, allows to programatically create visual graphs and networks.

(use-package graphviz-dot-mode
  :straight (:build t)
  :defer t
  :config
  (setq graphviz-dot-indent-width 4))
Markdown

Yes, I love org-mode and I largely prefer to use it instead of Markdown due to its far superior power and abilities. But still, sometimes I need to use Markdown because not everyone use org-mode, unfortunately.

(use-package markdown-mode
  :defer t
  :straight t
  :mode
  (("\\.mkd\\'" . markdown-mode)
   ("\\.mdk\\'" . markdown-mode)
   ("\\.mdx\\'" . markdown-mode))

            "xq"  #'markdown-blockquote-region)
  :hook (markdown-mode . orgtbl-mode)
  :config
  (setq markdown-fontify-code-blocks-natively t))

Since most of my Mardown files are related to Github, Id like to be able to render Markdown through its API.

(use-package gh-md
  :defer t
  :after markdown-mode
  :straight (:build t)
  :general
  (:keymaps 'markdown-mode-map
   :states 'normal
   :prefix ","
   "cr" #'gh-md-render-buffer))

Tables of content are always nice to have for large files, just like with the toc-org package for org-mode.

(use-package markdown-toc
  :defer t
  :after markdown-mode
  :straight (:build t)
  :general
  (:keymaps 'markdown-mode-map
   :states 'normal
   :prefix ","
   "iT" #'markdown-toc-generate-toc))

vmd-mode allows the user to live-preview their Github-flavored Markdown file quickly. Thats neat!

(use-package vmd-mode
  :defer t
  :after markdown-mode
  :straight (:build t)
  :custom ((vmd-binary-path (executable-find "vmd")))
  :general
  (:keymaps 'markdown-mode-map
   :states 'normal
   :prefix ","
   "cP" #'vmd-mode))
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.

(use-package nginx-mode
  :straight (:build t)
  :defer t)

We then also have an autocompletion package that adds to company the Nginx syntax.

(use-package company-nginx
  :straight (:build t)
  :defer t
  :config
  (add-hook 'nginx-mode-hook (lambda ()
                               (add-to-list 'company-backends #'company-nginx))))
Shells

Aside from Eshell, my main shell on my machine is fish (see my fish config), therefore I need a mode for it.

(use-package fish-mode
  :straight (:build t)
  :defer t)
Toml
(use-package toml-mode
  :straight (:build t)
  :defer t
  :mode "/\\(Cargo.lock\\|\\.cargo/config\\)\\'")
Yaml
(use-package yaml-mode
  :defer t
  :straight (:build t)
  :mode "\\.yml\\'"
  :mode "\\.yaml\\'")

General Programming Languages

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 wont make you a good C++ programmer, neither will the other way around. But, They are still somewhat related, and Emacs thinks so too.

(use-package cc-mode
  :straight (:type built-in)
  :defer t
  :init
  (put 'c-c++-backend 'safe-local-variable 'symbolp)
  :config
  (progn
    (require 'compile)
    (general-define-key
     :keymaps '(c-mode-map c++-mode-map)
     "," nil
     ";" nil)
    (general-define-key
     :states 'normal
     :keymaps '(c-mode-map c++-mode-map)
     :prefix ","
     "l"  '(:keymap lsp-command-map :which-key "lsp" :package lsp-mode))
    (general-define-key
     :states 'normal
     :keymaps '(c-mode-map c++-mode-map)
     "ga" #'projectile-find-other-file
     "gA" #'projectile-find-other-file-other-window)))

Something that is also important when working with these languages is respecting the .clang-format file that may be provided by a project.

(use-package clang-format+
  :straight (:build t)
  :defer t
  :init
  (add-hook 'c-mode-common-hook #'clang-format+-mode))

However, Emacs notion of C++ is somewhat outdated, so we need to update its fontlock.

(use-package modern-cpp-font-lock
  :straight (:build t)
  :defer t
  :hook (c++-mode . modern-c++-font-lock-mode))
CommonLisp
(add-hook 'lisp-mode-hook #'parinfer-rust-mode)
(add-hook 'lisp-mode-hook (lambda () (smartparens-mode -1)))
(use-package stumpwm-mode
  :straight (:build t)
  :defer t
  :config
  (general-define-key
   :keymaps 'stumpwm-mode-map
   :states 'normal
   :prefix ","
   "e"  '(:ignore :which-key "eval")
   "ee" #'stumpwm-eval-last-sexp
   "ed" #'stumpwm-eval-defun
   "er" #'stumpwm-eval-region))
Dart
(use-package dart-mode
  :straight (:build t)
  :defer t
  :mode "\\.dart\\'")
(use-package lsp-dart
  :straight (:build t)
  :defer t)
EmacsLisp

This package displays the functions arglist or variables docstring in the echo area at the bottom of the frame. Quite useful indeed.

(use-package eldoc
  :defer t
  :after company
  :init
  (eldoc-add-command 'company-complete-selection
                     'company-complete-common
                     'company-capf
                     'company-abort))
(add-hook 'emacs-lisp-mode-hook (lambda () (smartparens-mode -1)))

Lets also declare some Elisp-dedicated keybindings, prefixed by a comma.

(general-define-key
 :states 'motion
 :keymaps 'emacs-lisp-mode-map
 :prefix ","

 "'"   #'ielm
 "c"   '(emacs-lisp-byte-compile :which-key "Byte compile")

Rust

Rust is a general programming language, akin to C++ in some ways, but much more oriented towards safe code, and much better suited for web development. First, lets install the most important package, rustic.

(use-package rustic

  :straight (:build t)

  :init
  (after! org-src

Fringe

Its nice to know which lines were modified since the last commit in a file.

         (org-mode      . git-gutter-mode)
         (markdown-mode . git-gutter-mode)
         (latex-mode    . git-gutter-mode)))

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! Ill (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 youll need to install them with the command M-x all-the-icons-install-fonts.

(use-package all-the-icons
  :defer t
  :straight t)

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!

(dolist (symbol '(("lambda" . 955)
                  ("mapc" . 8614)))
  (add-to-list 'prettify-symbols-alist symbol))

Lets enable this mode for any programming mode:

(add-hook 'emacs-lisp-mode-hook #'prettify-symbols-mode)

Ligatures

The font Im using (see §#Basic-configuration-Visual-Configuration-Fontsxfkjel6184j0) supports ligatures, but Emacs in GUI mode does not. And of course, theres a package for that.

(use-package ligature
  :straight (ligature :type git

  (ligature-set-ligatures '(eww-mode org-mode elfeed-show-mode)
                          '("ff" "fi" "ffi"))

Modeline

(use-package doom-modeline
  :straight (:build t)
  :defer t
  :init (doom-modeline-mode 1)
  :custom ((doom-modeline-height 15)))

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.

(use-package secret-mode
  :defer t
  :straight (secret-mode :build t
                         :type git
                         :host github

Rainbow Delimiters

(use-package rainbow-delimiters
  :straight (:build t)
  :defer t

Yall want some more COLORS?

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

(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))

Misc

ArchWiki pages

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

(use-package archwiki
  :defer t
  :straight (archwiki :build t
                      :type git
                      :repo "https://labs.phundrak.com/phundrak/archwiki.el"))

avy

avy is a really convenient way of jumping around, but Ill need some configuration to make it bépo-compatible.

(use-package avy
  :defer t
  :straight t
  :config
  (setq avy-keys '(?a ?u ?i ?e ?c ?t ?s ?r ?n))
  :general
  (:states 'normal
   "gl" #'avy-goto-line))

Calc

Lets give calc-mode some better defaults.

(setq calc-angle-mode    'rad
      calc-symbolic-mode t)

Elcord

(use-package elcord

  (setq elcord-use-major-mode-as-main-icon t
        elcord-refresh-rate                5
        elcord-display-elapsed             nil))

ivy-quick-find-files.el

  (add-to-list 'global-mode-string '("" mode-line-keycast " ")))

SICP

Who would get interested in Emacs and not want to read the SICP? Moreover, inside Emacs?

(use-package sicp
  :straight (:build t)
  :defer t)

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.

(use-package winum
  :straight (:build t)
  :init (winum-mode))

Ytplay

ytplay is a small package Ive written with which you can choose at which resolution to play a YouTube video in an external video player.
