This repository contains my Emacs configuration. It is written and documented in literate programming style.
If you’re new to Emacs and just want to have a look around: Lean back and relax while enjoying a deep dive into the wonderful world of the Emacs editor. I have a talk “Play Emacs like an instrument” which is a small teaser of what Emacs can do - and what kinds of features you’ll find in this repository: https://www.youtube.com/watch?v=gfZDwYeBlO4
Initial
Emacs configuration is usually done in the home directory in the
.emacs.d folder. This holds true for Unix and Linux systems. For
Windows, look it up here.
git clone https://github.com/munen/emacs.d.git ~/.emacs.d
Emacs dependencies/libraries are managed via the internal package
management system. To initially install packages, open
~/.emacs.d/init.el, refresh your package list with M-x
package-refresh-contents and install everything using M-x
eval-buffer.
I’m running Debian and for some things I use GNU Guix for package management. This Emacs config started out using just package.el, but it’s moving towards using Guix whenever possible. The benefits are plenty:
- No package drift
- Ability to install dependencies outside of Emacs (fonts, binaries, etc)
- Reproducibility
- Transactional upgrades with the option to roll back
Spread throughout this config, there are source blocks with
:noweb-ref packages config. They define Guix packages which are
tangled into one Emacs manifest, so that all things Emacs are well
defined in just one config file.
(specifications->manifest
'("emacs"
<<packages>>
))
This adds the installed packages to the standard Emacs load path, so
that require just works.
;; Single directory
;; (add-to-list 'load-path "~/.guix-profile/share/emacs/site-lisp/mu4e")
;; All sub directories
(let ((default-directory "~/.guix-profile/share/emacs/site-lisp/"))
(normal-top-level-add-subdirs-to-load-path))https://github.com/yilkalargaw/org-auto-tangle
Whenever a change to the Guix package blocks is made, it would be
possible to manually call M-x org-babel-tangle (C-c C-v t).
With auto-tangle, it’s a bit more convenient, though.

This section contains settings for built-in Emacs features.
Emacs 26.1 (for example in Debian Buster) requests the GNU Elpa repo with the wrong TLS version - which makes the request fail. This is a manual patch for older versions of Emacs. It’s fixed from 26.3 and above upstream.
(if (string< emacs-version

because several text-modes (markdown, mails) enjoy the pain of long

modes have a visual-line-mode= configuration which makes the text
look nice locally, at least.
(add-hook 'org-mode-hook 'auto-fill-mode)https://github.com/joostkremers/visual-fill-column
visual-fill-column-mode is a small Emacs minor mode that mimics the
effect of fill-column in visual-line-mode. Instead of wrapping
lines at the window edge, which is the standard behaviour of
visual-line-mode, it wraps lines at fill-column. If fill-column
is too large for the window, the text is wrapped at the window edge.
Enable whenever upstream visual-line-mode is activated.
(add-hook 'visual-line-mode-hook #'visual-fill-column-mode)Enable visual-fill-mode for all text based modes:

;; (add-hook 'text-mode-hook 'visual-line-mode)Enable adative-wrap-prefix-mode:
https://elpa.gnu.org/packages/adaptive-wrap.html
This package provides the `adaptive-wrap-prefix-mode’ minor mode which sets the wrap-prefix property on the fly so that single-long-line paragraphs get word-wrapped in a way similar to what you’d get with M-q using adaptive-fill-mode, but without actually changing the buffer’s text.

Emacs supports editing text written in scripts, such as Arabic, Farsi, and Hebrew, whose natural ordering of horizontal text for display is from right to left. However, digits and Latin text embedded in these scripts are still displayed left to right.
Whilst this is a great feature, it adds to the amount of line scans that Emacs has to do to render a line. Too many line scans will cause Emacs to hang. Since I personally do not work with right-to-left languages, I’m defaulting to displaying all paragraphs in a left-to-right manner.
(setq-default bidi-paragraph-direction 'left-to-right)
(if (version<= "27.1" emacs-version)
(setq bidi-inhibit-bpa t))When the lines in a file are so long that performance could suffer to an unacceptable degree, we say “so long” to the slow modes and options enabled in that buffer, and invoke something much more basic in their place.

PDF, I use pdf-tools to preview the PDF and shortcuts to
automatically save, compile and reload on demand.
Here is a screencast showing how I edit Markdown or org-mode files in Emacs whilst having a PDF preview.
In a screenshot, it looks like this:
(defun md-compile ()

This is actually faster than the default way of Emacs or that of VIM. The following code ports that functionality to Emacs.

Within this file, I’ll search for passwords with counsel-imenu which

Since Emacs is a multi-purpose LISP REPL, there are many modes that
are not primarily (or not at all) centered about text-manipulation.

shortcuts.

Integrant configures, starts and manages a system and exposes a
lifecycle for it.
For REPL-driven development this adds one layer of indirection: When
starting a service through lein run (or bundled in a Docker
container), the system will already be started by Integrant. Without
having a ref to this system, we cannot stop it, we can only start
new systems. This means that reloading the code will only start new
systems, but not be able to halt the old one. The internal code from
Integrant relies on spawning a thread after initializing a system
through lein run and will not return until the process is done.
Therefore we cannot retrieve the system when running lein run.
When Emacs has a connection to a REPL for an Integrant based application, this snippet actually enables reloading of front and back-ends. The code doesn’t use cider internal functions for interacting with the REPL, because not all buffers might be connected (for example the CLJS buffers might not have a dedicated REPL themselves). Instead, it uses common Elisp.

Automatically format code for different languages and frameworks.
This implements the interactive function autoformat which is a thin
wrapper around command-line based code autoformatters which it
utilizes through a strategy pattern.
To add a new language/framework, the only required change is to add
the respective command-line tool configuration into a separate
strategy function. It is trivial to do if the new language/framework
has a command-line tool which takes code into stdin and formats it
to stdout.
It’s possible to install the dependencies locally, so that the setup doesn’t impose dependencies on team members - or they can be installed through the respective packages managers (npm/yarn) to enforce code guidelines.
This requires prettier, @prettier/plugin-ruby and
prettier-eslint-cli to be installed:

I installed whisper.ccp manually on the commandline, though whisper.el supports automatic installation.
I benchmarked different models against each other. The “base” model is quite fast and has good results. “tiny” has worse results and starting from “small”, the computation time goes way up.
Also, I’ve benchmarked whisper.cpp streaming vs whisper.el and the latter is far superior.
Note that setting the whisper-language to ‘auto’ implies that one
recording can only have one language. Giving it multiple sentences
in different languages will not return a happy result.

(require 'org-tempo))A lightweight implementation of the Pomodoro Technique is implemented through customizing Org mode. These are the commands:
ok-pomodoro-startok-pomodoro-cancelok-pomodoro-breakok-pomodoro-reset: Reset the completed and cancelled counters.
It sets the following stats:
ok-pomodoro-completedok-pomodoro-cancelled
Alternatively, if you do not want to manually start a pomodoro, you
can hook into the Org mode clocking mechanism. When
ok-pomodoro-auto-clock-in is set, for every Clock that is started
(C-c C-x C-i) an automatic Timer is scheduled to 25min. After these
25min are up, a “Time to take a break!” message is played and a pop-up
notification is shown.
The timer is not automatically stopped on clocking out, because clocking in should still work on new tasks without resetting the Pomodoro.
The timer can manually be stopped with M-x org-timer-stop.
A break can be started with M-x pomodoro-break. A pomodoro can also
manually be started without clocking in via M-x pomodoro-start.
;; Configure primary org pomodoro buffer to which the timers will get
;; attached to.

(load "~/.emacs.d/org-pomodoro")I use two workflow sets:
- One for TODOs which can either be TODO or DONE
- Another for tasks that I am WAITING for something to happen or which are in PROGRESS
Additionally I sometimes use the keywords PROJECT and AGENDA to denote special bullets that I might tag (schedule/deadline) in the agenda. These keywords give semantics to those bullets.
Note that “|” denotes a semantic state change that is reflected in a different color. Putting the pipe at the end means that all states prior should be shown in the same color.
(setq org-todo-keywords

| Headline | Time |
|---|---|
| Total time | 1d 1:03 |

not), I do prefer that the summation is done only in fractional hours.
org-duration-format is very powerful, the help is helpful to
understand the syntax and options.
(setq org-duration-format '(("h" . t) (special . 2)))This will render the same time as above as:

PDF Tools is, among other things, a replacement of DocView for PDF files. The key difference is that pages are not pre-rendered by e.g. ghostscript and stored in the file-system, but rather created on-demand and stored in memory.
PDF Tools for me is - hands down - the best PDF viewer! It’s not an excuse to do even more within Emacs.

Luckily, there’s good extensions for both Chrome/Chromium and Firefox to have a live binding to an Emacs session.
There is a good Emacs package called Atomic Chrome which is similar to Edit with Emacs, but has some advantages as below with the help of websockets:
- The input on Emacs is reflected to the browser instantly and continuously.
- You can use both the browser and Emacs at the same time. They are updated to the same content bi-directionally.
The name “Atomic Chrome” is a bit misleading, because it actually supports the “GhostText” protocol which allows it to be used with Firefox, as well.
On Firefox, I’m using the GhostText addon. On Chromium, I’m using
the AtomicChrome extension. GhostText is also available for Chrome,
but it doesn’t work for me which is a non-issue, because both plugins
work just the same way: Enter a textarea, hit a button, Emacs opens
up, type the text, end the session with C-c C-c.
(require 'atomic-chrome)
;; Handle if there is an Emacs instance running which has the server already
;; started

Default mode
(setq atomic-chrome-default-major-mode 'markdown-mode)Copy to clipboard
Some websites have aggressive JS which triggers when text is entered
to a textarea which can lead to bugs in combination with AtomicChrome.
There’s some websites where I regularly lose the text that’s entered.
While I’m editing, the textarea is updating, but on C-c C-c, Emacs
closes and the textarea is empty. For such cases, I’m using this
simple workaround: Copy the contents to clipboard just before closing
Emacs. So if the contents are lost, I can just paste the text into the
textarea. Not a perfect solution, but this happens seldomly enough,
that it’s good enough for me.

Yes, there’s HTML mails and attachments, but at the core Email is probably the place where many people write and consume the most text. To utilize the best text-processing program available makes a lot of sense.
When combined with other powerful features of Emacs (such as Org mode for organizing mails into projects and todos), processing mails within Emacs not only makes a lot of sense, but becomes a powerhouse.
Emacs has many options for MTAs. I’m using MU4E which is a little
similar to using mutt with notmuch. As SMTP, I’m using the built-in
smtpmail Emacs package.
MU works on a local Maildir folder. For synchronization offlineimap is used. Install:
- Debian:
apt-get install offlineimap - macOS:
brew install offlineimap
For MU4E to work, install MU and MU4E:
- Debian:
apt-get install mu4e - Guix:
guix package -i mu - macOS:
brew install mu --with-emacs
For starttls to work when sending mail, install gnutls:
- Debian:
apt-get install gnutls-bin - macOS:
brew install gnutls
"mu"
- Configure
.offlineimaprcfile for IMAP - Configure
.authinfofile for SMTP - https://www.emacswiki.org/emacs/GnusAuthinfo
Tell Emacs where to find the encrypted .authinfo file.
(setq auth-sources
'((:source "~/.authinfo.gpg")))
To open PDFs within Mu4e with Emacs, then there’s one thing to
configure. Mu4e uses xdg-open to chose the app to open any mime type.

Disable colors for HTML mails. HTML mails, especially transactional ones, can be very convoluted. Converting them to text and taking away colors can make them more readable.
(setq shr-use-colors t)Disable “HTML over plain text” heuristic. This variable officially has this rationale: “Ratio between the length of the html and the plain text part below which mu4e will consider the plain text part to be ‘This messages requires html’ text bodies. You can neutralize it (always show the text version) by using `most-positive-fixnum’.”
This heuristic overwrites the default setting (and configuration) that Plain text should be preferred over HTML!
In my experience, HTML Emails are WAY longer than only 5x the Plain text (Doodle, Airbnb, Meetup, etc), so this will yield me a lot of false positives whereas I have never seen a “This message requires HTML” body.

Relevant RFC: https://tools.ietf.org/html/rfc3676
What is required is a format which is in all significant ways Text/Plain, and therefore is quite suitable for display as Text/Plain, and yet allows the sender to express to the receiver which lines are quoted and which lines are considered a logical paragraph, and thus eligible to be flowed (wrapped and joined) as appropriate.

Ivy, a generic completion mechanism for Emacs.
Counsel, a collection of Ivy-enhanced versions of common Emacs commands.
Swiper, an Ivy-enhanced alternative to isearch.
Ivy is an interactive interface for completion in Emacs. Therefore
it overlaps in functionality with ido. While Ivy is more powerful,
it breaks certain standard functionality. So ido is enabled globally
by default and for certain tasks, Ivy overrides ido.
Emacs uses completion mechanism in a variety of contexts: code, menus,
commands, variables, functions, etc. Completion entails listing,
sorting, filtering, previewing, and applying actions on selected
items. When active, ivy-mode completes the selection process by
narrowing available choices while previewing in the minibuffer.
Selecting the final candidate is either through simple keyboard
character inputs or through powerful regular expressions.

(defalias 'thesaurus-openthesaurus-de 'synosaurus-lookup)Emacs has built-in functionality for checking and correcting spelling
called ispell.el. On top of that, there’s a built-in minor mode for
for on-the-fly spell checking. called flyspell-mode.
Flyspell can use multiple back-ends (for example ispell, aspell or hunspell).
Do not order not by the default of alphabetical ordering.
(setq flyspell-sort-corrections nil)When checking the entire buffer, don’t print messages for every word. This is a major performance gain.
(setq flyspell-issue-message-flag nil)Here in Switzerland, there are four official languages: Swiss German, French, Italian and Romansh. Also, we converse a lot in German and English. Hence, it’s a regular occurrence to have one file with multiple languages in them. Especially for these situations it’s still to have proper spell checking. Fortunately, Emacs has us covered!
Hunspell is a free spell checker and used by LibreOffice, Firefox and
Chromium. It allows to set multiple dictionaries - even different
dictionaries per language (aspell, for example also allows multiple
dictionaries, but only for the same language). It also can be used as
an ispell.el backend.
To use hunspell, install it first:
apt install hunspell hunspell-de-de hunspell-en-gb hunspell-en-us hunspell-de-ch-frami
(with-eval-after-load "ispell"
;; Configure `LANG`, otherwise ispell.el cannot find a 'default
;; dictionary' even though multiple dictionaries will be configured
;; in next line.
(setenv "LANG" "en_US")
(setq ispell-program-name "hunspell")
;; Configure German, Swiss German, and two variants of English.
(setq ispell-dictionary "de_DE,de_CH,en_GB,en_US")
;; ispell-set-spellchecker-params has to be called
;; before ispell-hunspell-add-multi-dic will work
(ispell-set-spellchecker-params)
(ispell-hunspell-add-multi-dic "de_DE,de_CH,en_GB,en_US"))
;; For saving words to the personal dictionary, don't infer it from
;; the locale, otherwise it would save to ~/.hunspell_de_DE.
(setq ispell-personal-dictionary "~/.hunspell_personal")
;; The personal dictionary file has to exist, otherwise hunspell will
;; silently not use it.

The following packages would be nice, in theory. In practice something is yet amiss, but it might be different in the future. That’s why I’m keeping them around and will try them at another time.
https://github.com/bburns/clipmon
Proposition: Monitors system clipboard and puts everything in the kill-ring.
Caveat: In theory, I liked the package. However, it seemed to cause racing conditions and crashed Emacs multiple times a day. When this is re-implemented in a non-blocking mode, this would be nice.
;; (add-to-list 'after-init-hook 'clipmon-mode-start)Theoretically this is really nice to have functionality. However, I couldn’t run it for long. Emacs started freezing a lot on the day when I added this lib. I assume, because clipmon is blocking - and I always run multiple instances of Emacs in parallel. They might be in for a classic racing condition. Might be just another bug.
