Welcome! You found my (Marcel Kapfer aka mmk2410) personal Emacs configuration file. Please feel free to read through it, use it or get inspiration! If you would (for some very strange reason) like to read it online: I published it to config.mmk2410.org
This file (config.org) is written in org-mode and converted as Emacs Lisp to config.el on startup. This is achieved on org-babel and tangle (see the init.el file).
There are many people that I should thank for giving me the help needed to write this config. Two of them need to be mentioned here since many parts are either copied or heavily inspired by their configurations:
- Karl Voit especially for his Evolution email workflow and this setup approach (his Emacs config)
- David Wilson and his System Crafters YouTube channel for his Emacs videos (his Emacs config)
Note: Elisp blocks which are marked as :tangle no are not evaluated.
A few words on setup
Writing the initial "stable" version of this configuration took nearly two years. I used it constantly during this time after I declared Emacs bankruptcy with my old configuration. During this time many things happened and changed Back in March 2019 when I started I never imaged using this configuration on a native Microsoft® Windows® installation of Emacs. But in 2021 when I started using some creative tools that are only available on Windows® I first did and only later switched completely to the Windows Subsystem for Linux. Therefore some parts are compatible with a native installation of Emacs on Windows®.
For Microsoft(R) Windows(R) users it is highly adviced to set the HOME environment variable to the users home directory. This can be done by opening the file explorer WIN+e, right clicking on "This PC" and choosing "Properties". In the opening window it is possible to open "Advanced system settings" in the sidebar. In the then appearing dialg ther is a button labeled "Environment Variables…". Using the "New…" button in the "User variables" section of the "Environment Variables" dialog it is possible to add a new one. Enter as name HOME and use the "Browse Directory.." button for choosing your user home directory. Accept all the changes by clicking on "OK" until there are no more open dialogs left.
General settings
Settings for Emacs in general as well as for my personal setup.
macOS Adjustments
First define a variable for making MacOS specific adjustments a bit easier.
(setq on-macos (eq system-type 'darwin))For using the Macbook keyboard effectively with Emacs I made some adjustments based on some suggestions found on the internet.

(save-place-mode t)Spell checking
Enable aspell. Options set according to Emacswiki: FlySpell
(setq-default ispell-program-name "aspell")
(setq ispell-list-command "--list")For using spell checking on Microsoft(R) Windows(R) a little bit more work is apparently needed. First of all some spell checking program is needed and when trying to install either ispell, aspell or hunspell I run into the problem that all three of them are primarily developed for Linux systems.
For installing aspell and the required dictionaries I decided to use MSYS2. After installing this and following the initial setup guide on their website I installed aspell using pacman -S mingw-w64-x86_64-aspell in an MSYS2 terminal (for the next steps it was also necessary to install the make program with pacman -S make). The installation itself does not make the program available to my Emacs installation (see A few words on setup) but I needed to add the C:\msys64\mingw64\bin directory to the Windows Path variable. Therefore I opened an explorer (WIN+e), right-clicked "This PC" and then properties. In the appearing window I continued by clicking "Advanced system settings" in the sidebar. In the now appearing window I continued by clicking the "Environment Variables…" button. There I edited the Path system variable. By clicking on "New" first and then clicking on "Browse…" I was able to add the previously named directory to the path. Afterwards it is possible to check weather this was successful by either opening a PowerShell or CMD prompt and executing aspell --version.
While Emacs now finds aspell (at least after a restart of Emacs) it does not find any dictionaries and therefore not work. This is quite understandable since by default non are installed. Apparently compared to some Linux distributions MSYS2 does not provide any dictionaries through their repositories. So I downloaded the ones I needed from the aspell dictionaries website. Using the MSYS2 MinGW 64-bit terminal (this is important, the MSYS MSYS2 one does not work for this) I could extract them with tar xjf aspell6-en-2020.12.07-0.tar.bz2 and switch to the extracted directory. Following the provided README I first run ./configure and the executed make. Since the make install step fails by default I needed to adjust the Makefile by deleting the two lines that change the directory and execute chmod 664 in the install rule. Afterwards running make install succeeded without any errors.
After re-visiting the current file or opening another one spell checking in Emacs works!
scratch-buffer
I prefer that the mode of my scratch buffer is org and don't want any initial lines.
(setq initial-scratch-message nil)
(setq initial-major-mode 'org-mode)doc-view
Set doc-view resolution to 300 for sharp PDFs.

(delete-selection-mode t)Vertical bar as cursor
(setq-default cursor-type 'bar)Hide tool bar, menu bar and scroll bar
I get scroll bars when using Emacs with emacsclient. So I disable the scroll-bar-mode explicitly when creating a new frame, but only on graphical systems. The same fix is also applied for the typeface.

(show-paren-mode 1)Fix wrong Emacs size in some window managers
I have the problem in BSPWM that Emacs always starts floating and does not obey my rule to start in tiling mode.
Setting frame-resize-pixelwise to non-nil (as described in GitHub: baskerville/bspwm #551) solves this problem.
(setq frame-resize-pixelwise t)Set typeface
My typeface is not loading when using emacsclient. So I set it explicitly when creating a frame. The same fix is applied for the scroll bars.

During the last weeks I got used to using a light theme during daytime and a dark theme during nighttime. Luckily the themes based on Atom One are to my liking and the doom package provides a dark and light variant. One thing that was difficult with Emacs was actually switching theme since it involved disabling all current ones (for some reason on one machine there are two enabled while on the other machine its only one) and then loading the correct one. These functions try to make that process easier, at least for now. The long-term goal is to automatically change the theme based on the current system-wide setting.

For easily choosing the next thing to work on I give each of my tasks a context (following the GTD methodology). For quickly getting a list of all actionable tasks for a context I'd like to have a quick keyboard shortcut to view a custom agenda. For this I defined a list of contexts and their shortcut and iterated over them to create an additional org-agenda-custom-commands entry for each.

I am currently exploring the option in Org mode to export a file (or some entries) to an ics-file which I can then in turn import into my calendar. For reliably creating (and most importantly: updating) entries it is necessary that each one has an unique ID. To create a ID for the current entry I could just run M-x org-id-get-create and for an entire file execute the following Emacs Lisp (org-map-entries 'org-id-get-create). Of course this is not an ideal solution. But adding this s-expression to org-mode-hook would create IDs in all Org file I edit which I also don't like. Since the amount of files I do want the automatic creation is (currently) not that large it is OK for me to do some work on my own, at least if it is only a one time setup.
The idea which I had to achieve this goal was to create a file-local variable (called mmk2410/org-create-uuids) that I set to t in the buffers I need the automatic adding of IDs and adding a hook to org-mode-hook that in turn adds a hook to before-save-hook for calling the function mmk2410/org-create-all-uuids that executes the previously named s-expression to add a ID to each entry in the buffer.

Until now I did not think that I needed to keep a (personal) journal. But since I is recommended to keep a journal of whom you met due to the corona pandemic I started thinking about setting up one. Further use cases came then to my mind and so I decided to give it a try. Therefore the configuration is still in a very early state and may change quite soon.
(use-package org-journal
:config (setq org-journal-dir "~/org/journal"
org-journal-file-type 'monthly
org-journal-find-file 'find-file
org-journal-file-format "%Y-%m-%d.org"
org-journal-date-format "%A, %Y-%m-%d")
:bind (("C-c j j" . 'org-journal-new-entry)
("C-c j s" . 'org-journal-new-scheduled-entry)
("C-c j o" . 'org-journal-open-current-journal-file)
("C-c j w" . 'mmk2410/org-journal-worktime)))
Part of my workflow with org journal is in the meantime to clock the time I work in the different entries using org-clock. At the end of the day I like to create a summary for that. Currently the process for this includes a table with to formulas I created some time ago and copy every day from the previous one (while the first formula calculates the times the second is just there to clean the fields). While this is certainly improvable in many ways the only thing that really annoyed me was the calculation of the time. Since I try to follow the 52:17 methodology I have to add many numbers around 52 up to get the usual hour:minutes format. Although this is certainly a good brain training it has been shown that the calculation is very error-prone and calculating this twice does not make it more fun.
Therefore I created a little interactive helper function to sum these times up. The function mmk2410/org-journal-worktime reads a list of space separated minute values (so the time 1:04 must be entered as 64) and returns it as an minibuffer message in the required format (hh:mm).
(defun mmk2410/org-journal-worktime (workmins)
"Sum up the entered minutes and return it in hh:mm format."
(interactive "Show many minutes did you work today? ")
(let ((worksum (apply '+ (mapcar 'string-to-number (split-string workmins)))))
(message "Total work time: %d:%d" (/ worksum 60) (mod worksum 60))))I am quite sure that the function can be improved in various ways. I am not a Lisp hacker and have not written very much in it. But at the moment it fits my needs (and I currently do not have more time to spare on this).

The beast itself
For joining IRC channels I use ERC. For connecting with the network (using my ZNC bouncer) I would like to just press a keybinding. Therefore I warp the call to erc-tls with the correct arguments in the following function (which is later bound to C-c i j).

Normally I use Firefox for browsing the web, but when I am working with full focus in Emacs I sometimes prefer eww. For example while reading a paper and taking notes on it. In this case I don't want to lose my focus while switching to a web browser (and potentially see some open tabs from another project).
In recent times I have gotten really bad search results on DuckDuckGo (either I can't search anymore or they really got worse). So I'm using Startpage at the moment.
More important for me while reading a paper is looking up some things on Wikipedia. So I defined – additionally to a simple keybinding for eww itself – a function and a keybinding for searching on the English Wikipedia.

Since now I used many different RSS feed solutions. I started with Feedly back in 2013/14, switched later to a self-hosted TinyTinyRSS and then to Nextcloud News. After some time using this solution, its many bugs annoyed me more and more and I finally switched to FreshRSS in early 2021. Since early October I'm trying Miniflux. Although I had no problems with FreshRSS the interface of Miniflux (especially on mobile) is IMO nicer (though a little bit more eye-candy would be nice).
Mostly I use Miniflux through its web app—on mobile and on the desktop as well. But I have used and liked elfeed in the past and so I keep it configured properly.
elfeed package
This is the elfeed program itself.
As with email I prefer showing older entries first so I can catch-up with these first before getting to newer stuff. Other than the binding to C-c e there is nothing interesting left to see here.

(use-package elfeed
:demand t
:config (setq elfeed-sort-order 'ascending)
:bind (("C-c e" . elfeed)))Storing articles
Currently I am not using this since I need the actual articles offline for reading in some situation and therefore currently rely on Pocket.
I like to call myself quite an avid org-mode user and so I also want to store RSS articles I read with Elfeed in a reading list. Since from time to time I prefer to use my tablet or smartphone to read instead of sitting at the computer and it is a little bit cumbersome to use Emacs with Elfeed using Termux I prefer using the fantastic Orgzly app. The problem is now that I cannot just org-store-link in the org-capture template for Elfeed entries since this would store a link to the corresponding Elfeed entry. While I can open such links at my desktop I cannot in Orgzly. And also on desktop I most likely will open the article in my web browser instead of viewing just the RSS entry. Therefore it would be very practical if the capture template would not store a Elfeed link but directly the web link. Additionally would also like to store the Feed title as part of the note.
Therefore I need a org-capture template which fetches these functions. And since I can only get the Elfeed entry properties in the buffer with the entry I cannot just use the %(EXP) option alone but need a function that switches to the Elfeed buffer, gets the property and then inserts the value in the capture template. For this I wrote the following function which does exactly this (thanks to RichieHH who put me on the right track).
(defun mmk2410/org-capture-elfeed-entry-props (prop-function)
(save-window-excursion
(switch-to-buffer (org-capture-get :original-buffer))
(funcall prop-function elfeed-show-entry)))Using this function I can now define a org-capture template for my purpose.
(add-to-list 'org-capture-templates
'("a" "RSS Article" entry (file "~/org/tasks/read-review.org")
"* TODO %(elfeed-feed-title (mmk2410/org-capture-elfeed-entry-props 'elfeed-entry-feed)): [[%(mmk2410/org-capture-elfeed-entry-props 'elfeed-entry-link)][%(mmk2410/org-capture-elfeed-entry-props 'elfeed-entry-title)]]\n :PROPERTIES:\n :CREATED: %U\n :END:\n"
:immediate-finish t))elfeed-protocol
elfeed-protocol is a addition to Elfeed which enables the usage of some cloud RSS services (e.g. Nextcloud News, TT-RSS).
I currently use it in combination with my Miniflux instance (previously I used it with Nextcloud News and FreshRSS). The reason why I not only use elfeed with a local feed list (managed for example by elfeed-org) is that a cloud service can check for new feed articles continuously and I can read articles on any device.
I additionally bind elfeed-protocol-fever-reinit to a handy keybinding since this seems to be the only way to retrieve new items from the API.

(use-package pocket-reader)mu4e
Managing e-mails is maybe one of the most critical tasks in my life. Over the last years I tried countless different clients, including the famous (neo)mutt, KMail, and Thunderbird. But it seems that I always go back to one specific: mu4e. Maybe because it is integrated in Emacs and Org-mode, maybe because I like using a keyboard-focused client and that's where I end. I don't now. But what I know is: I enjoy using it!
Resources:
Load mu4e
Not all systems that I use have mu/mu4e installed. Either because I cannot really use it at work or because I'm running a native Windows instance or because I didn't completely setup the machine. Therefore I only load/execute the complete mu4e configuration if Emacs can find a mu executable.
(when (executable-find "mu") ;; Closed after all mu4e configuration
Not all distributions that I use have a enough up-to-date package of mu/maildir-utils in their repositories. Therefore on some system I compile and install it myself which ends in /usr/local instead of just /usr. Therefore I have a small function that finds the correct load-path for the mu4e package.
(eval-and-compile
(defun mmk2410/mu4e-load-path ()
(let* ((mu4e-site-lisp-path "/share/emacs/site-lisp/mu4e")

Using the determined load path I now load mu4e itself and bind it to a handy keybinding. Since I don't close the parenthesis of the use-package everything that follows this source code blocks is part of the config section.

(setq mu4e-headers-date-format "%Y-%m-%d %H:%M")For settings my header fields, I want to define a custom header field, which shows just an excerpt of my maildir path. My paths – created by mbsync – begin with the account name, which I want to shorten to just one letter. Since I archive my mail but let mu4e show me related mails, I want also to shorten the "Archive" path to "A". So the maildir path my be a short as e.g "m/INBOX" or "m/A".

I want to use the IMO improved :from-or-to header field instead of only a :from. Next to that I prefer to show the subject in a thread only once for a cleaner overview.

Since I try to keep an empty inbox and either reply to mails instantly or create a todo from them handling "old" mails should one the one hand be rare and on the other hand much more urgent. Actually I want them to distract and annoy me so that I handle them sooner than later.
(setq mu4e-headers-sort-direction 'ascending)As already said, I like to archive my mail and have as few mailboxes as possible. Since I get some mails over different addresses and in different mailboxes mu4e displays only one and doesn't show the duplicate. So when I mark the message I see for archiving and refresh the list while applying the mark the then hidden duplicate is now shown and I have to mark that again for archiving. Since the mailbox is shown I also can tell which one to archive if necessary. That is why I disable the skipping of duplicates:
(setq mu4e-headers-skip-duplicates nil)Message view customizations
By default mu4e jumps to the next message when pressing SPC at the end of a message. I explicitly do not want that behavior.
(setq mu4e-view-scroll-to-next nil)
I like to keep my Downloads folder quite empy and also download everything that I don't intent to keep to /tmp.
(setq mu4e-attachment-dir "/tmp")
The mu4e manual says, that viewing inline images may be not always correct. Let's try it anyway and find out how bad it really is. Additionally it is recommended, that imagemagick-register-types is called.
(setq mu4e-view-show-images t)
(when (fboundp 'imagemagick-register-types)
(imagemagick-register-types))I like to see the complete addresses and not just the name.
(setq mu4e-view-show-addresses t)Compose messages
I prefer to BCC myself in mail so I now that a message was handled by the mail server and thereby I can also put all mails of a thread in the same folder which makes searching a bit easier. So I let mu4e automatically set the BCC header when I start to compose a message.
(add-hook 'mu4e-compose-mode-hook
(lambda ()
(save-excursion
(message-add-header (concat "Bcc: " user-mail-address "\n")))))Since I get the emails via the BCC it is useless to also put them in a send folder.

Since I already have a msmtp client configured and would also use it in case I would use mutt, I want to use it also in mu4e. Setting msmtp as default SMTP client is quite easy but is it a little bit harder to set the account that should be used for sending. Therefore I wrote a lambda function that chooses the account and passes it as extra arguments based on the senders email address.

I like to get to some maildir quite fast and with a shortcut.

I use org-mode heavily and also manage my todos within it. Since my INBOX is not a todo list I like the idea of quickly add a mail as a todo.
(if (mmk2410/work)
(add-to-list 'org-capture-templates
'("m" "mail" entry (file "~/org/tasks/inbox.org")
"* TODO %a%? :@work:\n:PROPERTIES:\n:CREATED:%U\n:END:\n"))

Multiple mail accounts in mu4e can be achieved by using so called contexts.
First of all I like mu4e to only ask me, which content to use, if it can't figure it you.
(setq mu4e-context-policy 'ask
mu4e-compose-context-policy 'ask)Now define the contexts.

The org-mime package thankfully allows sending HTML mails from mu4e. Not that I like HTML mails but I need to have a special HTML message signature for work.
(use-package org-mime
:after (org mu4e)
:config (setq org-mime-library 'mml))Mu4e displays a message in the minibuffer after refreshing. And since I run mbsync and mu index (through emacsclient) automatically every few minutes these messages can get quite distracting. Luckily mu4e provides an option to disable these index messages.
(setq mu4e-hide-index-messages t)Mu4e show its current search in the modeline and as you may have already noticed, my default searches tend to be large. So I increase the shown characters from 30 to 60.
(setq mu4e-modeline-max-width 60)It is maybe not surprising that I am subscribed to some mailing lists. Some of these have quite some long names and so I would like to use a some alias for the display of these names. Thanks god mu4e also provides a possibility for this!
(setq mu4e-user-mailing-lists '(("debian-user.lists.debian.org" . "DebUsr")
("debian-security-announce.lists.debian.org" . "DebSecAnn")))
Finally the mu4e configuration is done! So lets close the parenthesis left open since the use-package call and the (when call.

Since my work place is using Microsoft Outlook for Email including its appointment features I sadly needed to switch away from mu4e to Evolution, as recommended by Karl Voit. Using his configuration as an inspiration and source I could setup the following workflow.
I first define the path to my evolution binary.
(setq mmk2410/evolution-path "/usr/bin/evolution")
Then I copied and slightly adjusted Karl Voits function for handling message-id link in Org mode.
(defun mmk2410/open-message-id-in-evolution (message-id)
(interactive)
(start-process
(concat "mid: " message-id)
nil
mmk2410/evolution-path
(concat "mid:<" message-id ">")))
(org-link-set-parameters "messageid" :follow #'mmk2410/open-message-id-in-evolution)The following function from him takes care of the other way: bringing a message as a link into Org mode.
(defun mmk2410/convert-mail-header-to-org-link ()
"Assumes an email header in the killring, parses it and returns an org mode link for it."

Tab Bar Setup
Since version 27 Emacs features a tab bar. In contrast to e.g. a browser a tab does not display just one file/buffer/window but an Emacs tab features an entire window configuration. Since I use Emacs not just for programming but (perhaps even mainly) for personal information management (including mail, agenda, journal, IRC and RSS) I had the idea to have one Emacs frame open with different tabs for all these things. Therefore I wrote a small package found in packages/mmk2410-tab-bar-helpers.el which I explain in a dedicated blog post.
(use-package mmk2410-tab-bar-helpers
:after (hydra)
:load-path "packages/"
:bind ("C-c f" . mmk2410/tab-bar/body))Work
For my workplace I have some additional packages and configuration that I keep in an own file.
