This configuration is inspired by [[https://github.com/unravel-team/emacs][Vedang's Prot-inspired literate config]]. As in
Vedang's, any unattributed quotes are taken directly from [[https://github.com/protesilaos/dotfiles/blob/master/emacs/.emacs.d/prot-emacs.org][Prot's org file]]. Also as in Vedang's, any
errors are probably his ;)
To make a change to this Emacs configuration, edit this file and then
type =C-c C-v C-t= (=M-x org-babel-tangle=) to republish all the
relevant files.
#+begin_quote
What you are now reading is not a common literate configuration of
Emacs. In most such cases, you have a generic =init.el= with a call to
the ~org-babel-load-file~ function that gets an Org document as its
value. That method works but is very slow, because we have to load Org
before starting Emacs (and Org loads a bunch of other things we do not
need at such an early stage).
Whereas this Org document serves as (i) a single point of entry to my
Emacs setup and (ii) the origin of all of my Emacs configurations.
While I am defining everything in a single Org file, I am not actually
starting Emacs by reading this file. Rather, I am instructing Org to
put the code blocks defined herein in standalone files, organised by
scope. The end result is something where you cannot tell whether a
literate program was executed or not.
This is the beauty of it. I can keep editing a single file as the
"source of truth", though I can still handle each of the files
individually (e.g. someone wants to see how I do a specific thing, so
I share only that file as an email attachment---no need to send over
this massive document).
When I want to modify my Emacs setup, I edit this file and then
evaluate the following code block or do =C-c C-v C-t=. All files will
be updated accordingly.

* The =early-init.el= file
#+begin_quote
This is the first file that Emacs reads when starting up. It should
contain code that does not depend on any package or the proportions of
the Emacs frame. In general, this early initialisation file is meant
to set up a few basic things before Emacs produces the initial frame
by delegating to the =init.el

These warnings are unnecessarily scary.
#+begin_quote
The =--with-native-compilation=yes= build option of Emacs is very
nice: it enables the "native compilation" of Emacs Lisp, translating
it down to machine code. However, the default setting for reporting
errors is set to a verbose value which, in my coaching experience,
confuses users: it produces warnings for compilation issues that only
the developer of the given package needs to deal with. These include
innocuous facts like docstrings being wider than a certain character
count. To make things even worse, the buffer that shows these warnings
uses the stop sign character, resulting in a long list of lines with
red spots everywhere, as if we have totally broken Emacs.

at this point: we activate the cache instead ([[#h:7a037504-8a2f-4df0-8482-ce6476354440][The =early-init.el= initialises the package cache]]).

I use ~elpaca~ for package management, and ~use-package~ for
configuration management. This means that ~elpaca~ replaces the
built-in ~package.el~ functionality.
When using ~elpaca~, here are some gotchas you should be aware of
(Note: these only apply for =:ensure t= cases):
1. Use ~elpaca-after-init-hook~ instead of ~after-init-hook~ or
~emacs-startup-hook~. Elpaca runs in the background and does not
guarantee order. Using this special hook ensures that config is
loaded in the expected order.
2. Prefer ~:demand~ or ~:wait~ over ~:defer~, especially when
deferring for a certain number of seconds. Do not make any
assumptions about order of execution.

This is something I learnt while studying Clojure: a ~comment~ macro
that wraps some code, effectively commenting it out, while keeping
indentation and syntax highlighting intact.
What I have here is technically not commenting out the code, because
the expansion of the macro is nil, not the actual code with comments
around it.
#+end_quote

The above is an example. What I actually use is the following. It
behaves the same as above, except when it reads a plist of the form
=(:eval t)=. The idea is for me to quickly activate something I want
to test by passing that to the macro. So here we have it:
#+end_quote
#+begin_src emacs-lisp :tangle "init.el"

"Determine what to do with BODY.

return BODY inside a `progn'.
Otherwise, do nothing with BODY and return nil, with no side
effects."
(declare (indent defun))
(let ((eval))
(dolist (element body)
(when-let* (((plistp element))

My ~cursory~ package provides a thin wrapper around built-in variables
that affect the style of the Emacs cursor on graphical terminals. The
intent is to allow the user to define preset configurations such as
"block with slow blinking" or "bar with fast blinking" and set them on
demand. The use-case for such presets is to adapt to evolving
interface requirements and concomitant levels of expected comfort,
such as in the difference between writing and reading.

This is yet another package of mine. It lets you preview a font inside
of Emacs. It does so in three ways:
- Prompt for a font on the system and display it in a buffer.
- List all known fonts in a buffer, with a short preview for each.
- Provide a major mode to preview a font whose file is among the
installed ones.

The built-in ~variable-pitch-mode~ makes the current buffer use a
proportionately spaced font. In technical terms, it remaps the
~default~ face to ~variable-pitch~, so whatever applies to the latter
takes effect over the former. I take care of their respective font
families in my ~fontaine~ setup ([[#h:cb41fef0-41a5-4a85-9552-496d96290258][The =nebkor-theme.el= section about ~fontaine~]]).
I want to activate ~variable-pitch-mode~ in all buffers where I
normally focus on prose. The exact mode hooks are specified in the
variable =prot/enable-variable-pitch-in-hooks=. Exceptions to these
are major modes that I do not consider related to prose (and which in
my opinion should not be derived from ~text-mode~): these are excluded
in the function ~prot/enable-variable-pitch~.

Bookmarks are compartments that store arbitrary information about a
file or buffer. The records are used to recreate that file/buffer
inside of Emacs. Put differently, we can easily jump back to a file or
directory (or anything that has a bookmark recorder+handler, really).
Use the ~bookmark-set~ command (=C-x r m= by default) to record a
bookmark and then visit one of your bookmarks with ~bookmark-jump~
(=C-x r b= by default).

#+begin_quote
Much like bookmarks, registers store data that we can reinstate
quickly ([[#h:581aa0ff-b136-4099-a321-3b86edbfbccb][The =nebkor-essentials.el= settings for bookmarks]]). A
common use-case is to write some text to a register and then insert
that text by calling the given register. This is much better than
relying on the ~kill-ring~, because registers are meant to be
overwritten by the user, whereas the ~kill-ring~ accumulates lots of
text that we do not necessarily need.
To me, registers are essential for keyboard macros. By default,
registers do not persist between Emacs sessions, though I do need to
re-use them from time to time, hence the arrangement to record them
with ~savehist-mode~ ([[#h:25765797-27a5-431e-8aa4-cc890a6a913a][The =nebkor-completion.el= settings for saving the history (~savehist-mode~)]]).

The ~expreg~ package by Yuan Fu (aka casouri) uses the tree-sitter
framework to incrementally expand the region from the smallest to the
largest syntactic unit in the given context. This is a powerful
feature, though it (i) requires Emacs to be built with tree-sitter
support and (ii) for the user to be running a major mode that is
designed for tree-sitter (Lisp seems to work regardless).

The ~completion-styles~ are pattern matching algorithms. They
interpret user input and match candidates accordingly.
- emacs22 :: Prefix completion that only operates on the text before
point. If we are in =prefix|suffix=, with =|= representing the
cursor, it will consider everything that expands =prefix= and then
add back to it the =suffix=.
- basic :: Prefix completion that also accounts for the text after
point. Using the above example, this one will consider patterns that
match all of ~emacs22~ as well as anything that completes =suffix=.
- partial-completion :: This is used for file navigation. Instead of
typing out a full path like =~/.local/share/fonts=, we do =~/.l/s/f=
or variants thereof to make the matches unique such as =~/.l/sh/fon=.
It is a joy to navigate the file system in this way.
- substring :: Matches the given sequence of characters literally
regardless of where it is in a word. So =pro= will match
=professional= as well as =reproduce=.
- flex :: Completion of an in-order subset of characters. It does not
matter where the charactes are in the word, so long as they are
encountered in the given order. The input =lad= will thus match
~list-faces-display~ as well as ~pulsar-highlight-dwim~.
- initials :: Completion of acronyms and initialisms. Typing =lfd=
will thus match ~list-faces-display~. This completion style can also
be used for file system navigation, though I prefer to only have
~partial-completion~ handle that task.
- orderless :: This is the only completion style I use which is not
built into Emacs and which I tweak further in a separate section
([[#h:7cc77fd0-8f98-4fc0-80be-48a758fcb6e2][The =nebkor-completion.el= for the ~orderless~ completion style]]).
It matches patterns out-of-order. Patterns are typically words
separated by spaces, though they can also be regular expressions,
and even styles that are the same as the aforementioned ~flex~ and
~initials~.
Now that you know about the completion styles I use, take a look at
the value of my ~completion-styles~. You will notice that ~orderless~,
which is the most powerful/flexible is placed last. I do this because
Emacs tries the styles in the given order from left to right, moving
the next one until it finds a match. As such, I usually want to start
with tight matches (e.g. =li-fa-di= for ~list-faces-display~) and only
widen the scope of the search as I need to. This is easy to do because
none of the built-in completion styles parses the empty space, so as
soon as I type a space after some characters I am using ~orderless~.

The ~orderless~ package by Omar Antolín Camarena provides one of the

It is a powerful pattern matching algorithm that parses user input and
interprets it out-of-order, so that =in pa= will cover ~insert-pair~
as well as ~package-install~. Components of the search are
space-separated, by default, though we can modify the user option
~orderless-component-separator~ to have something else (but I cannot
think of a better value). In the section about completion styles, I
explain how I use ~orderless~ and why its power does not result in
lots of false positives.

Minibuffer prompts often have a default value. This is used when the
user types =RET= without inputting anything. The out-of-the-box
behaviour of Emacs is to append informative text to the prompt like
=(default some-default-value)=. With the tweak to ~minibuffer-default-prompt-format~
we get a more compact style of =[some-default-value]=, which looks
better to me.

Here I combine several small tweaks to improve the overall minibuffer
experience.
- The need to ~resize-mini-windows~ arises on some occasions where
Emacs has to show text spanning multiple lines in the "mini
windows". A common scenario for me is in Org mode buffers where I
set the =TODO= keyword of a task with =C-c C-t= (=M-x org-todo=) and
have this as my setting: ~(setq org-use-fast-todo-selection 'expert)~
Otherwise, this is not an issue anyway and I may also like other
options for ~org-use-fast-todo-selection~.
- The ~read-answer-short~ is complementary to ~use-short-answers~.
This is about providing the shorter version to some confirmation
prompt, such as =y= instead of =yes=.
- The ~echo-keystrokes~ is set to a low value to show in the echo area
the incomplete key sequence I have just typed. This is especially
helpful for demonstration purposes but also to double check that I
did not mistype something (I cannot touch-type, so this happens a lot).
- The ~minibuffer-prompt-properties~ and advice to ~completing-read-multiple~
make it so that (i) the minibuffer prompt is not accessible with
regular motions to avoid mistakes and (ii) prompts that complete
multiple targets show an indicator about this fact. With regard to
the latter in particular, we have prompts like that of Org to set
tags for a heading (with =C-c C-q= else =M-x org-set-tags-command=)
where more than one candidate can be provided using completion,
provided each candidate is separated by the ~crm-separator~ (a comma
by default, though Org uses =:= in that scenario).
Remember that when using completion in the minibuffer, you can hit
=TAB= to expand the selected choice without exiting with it. For
cases when multiple candidates can be selected, you select the
candidate, =TAB=, then input the ~crm-separator~, and repeat until
you are done selecting at which point you type =RET=.
- Finally the ~file-name-shadow-mode~ is a neat little feature to
remove the "shadowed" part of a file prompt while using something
like =C-x C-f= (=M-x find-file=). File name shadowing happens when
we invoke ~find-file~ and instead of first deleting the contents of
the minibuffer, we start typing out the file system path we wish to
visit. For example, I am in =~/Git/Projects/= and type directly
after it something like =~/.local/share/fonts/=, so Emacs displays
=~/Git/Projects/~/.local/share/fonts/= with the original part greyed
out. With ~file-name-shadow-mode~ the "shadowed" part is removed
altogether. This is especially nice when combined with the
completion style called ~partial-completion~
([[#h:14b09958-279e-4069-81e3-5a16c9b69892][The =nebkor-completion.el= settings for completion styles]]).

Minibuffer prompts can have their own history. When they do not, they
share a common history of user inputs. Emacs keeps track of that
history in the current session, but loses it as soon as we close it.
With ~savehist-mode~ enabled, all minibuffer histories are written to
a file and are restored when we start Emacs again.
#+end_quote
#+begin_quote
Since we are already recording minibuffer histories, we can instruct
~savehist-mode~ to also keep track of additional variables and restore
them next time we use Emacs. Hence ~savehist-additional-variables~. I
do this in a few of places:
- [[#h:804b858f-7913-47ef-aaf4-8eef5b59ecb4][The =nebkor-completion.el= for in-buffer completion popup and preview (~corfu~)]]
- [[#h:5685df62-4484-42ad-a062-d55ab19022e3][The =nebkor-essentials.el= settings for registers]]
Note that the user option ~history-length~ applies to each individual
history variable: it is not about all histories combined.
Overall, I am happy with this feature and benefit from it on a daily
basis.

#+begin_quote
~consult~ is another wonderful package by Daniel Mendler. It provides
a number of commands that turbocharge the minibuffer with advanced
capabilities for filtering, asynchronous input, and previewing of the
current candidate's context.
- A case where filtering is in use is the ~consult-buffer~ command,
which many users have as a drop-in replacement to the generic =C-x b=
(=M-x switch-to-buffer=). It is a one-stop-shop for buffers,
recently visited files (if ~recentf-mode~ is used---I don't),
bookmarks ([[#h:581aa0ff-b136-4099-a321-3b86edbfbccb][The =nebkor-essentials.el= settings for bookmarks]]),
and, in principle, anything else that defines a source for this
interface. To filter those source, we can type at the empty
minibuffer =b SPC=, which will insert a filter specific to buffers.
Delete back to remove the =[Buffer]= filter and insert another
filter. Available filters are displayed by typing =?= at the prompt
(I define it this way to call the command ~consult-narrow-help~).
Every multi-source command from ~consult~ relies on this paradigm.
- Asynchronous input pertains to the intersection between Emacs and
external search programs. A case in point is ~consult-grep~, which
calls the system's ~grep~ program. The prompt distinguishes between
what is sent to the external program and what is only shown to Emacs
by wrapping the former inside of =#=. So the input =#prot-#completion=
will send =prot-= to the ~grep~ program and then use =completion=
inside of the minibuffer to perform the subsequent pattern-matching
(e.g. with help from ~orderless~ ([[#h:7cc77fd0-8f98-4fc0-80be-48a758fcb6e2][The =nebkor-completion.el= for the ~orderless~ completion style]]).
The part that is sent to the external program does not block Emacs.
It is handled asynchronously, so everything stays responsive.
- As for previewing, ~consult~ commands show the context of the
current match and update the window as we move between completion
candidates in the minibuffer. For example, the ~consult-line~
command performs an in-buffer search and lets us move between
matches in the minibuffer while seeing in the window above what the
surrounding text looks like. This is an excellent feature when we
are trying to find something and do not quite remember all the
search terms to narrow down to it simply by typing at the minibuffer
prompt.

[ Watch Prot's talk: [[https://protesilaos.com/codelog/2023-06-10-emacs-search-replace-basics/][Emacs: basics of search and replace]] (2023-06-10). ]
#+begin_quote
Emacs provides lots of useful facilities to search the contents of
buffers or files. The most common scenario is to type =C-s=
(~isearch-forward~) to perform a search forward from point or =C-r=
(~isearch-backward~) to do so in reverse. These commands pack a ton of
functionality and they integrate nicely with related facilities, such
as those of (i) permanently highlighting the thing being searched,
(ii) putting all results in a buffer that is useful for navigation
purposes, among others, and (iii) replacing the given matching items
with another term.
Here I summarise the functionality, though do check the video I did on
the basics of search and replace:
- =C-s= (~isearch-forward~) :: Search forward from point (incremental
search); retype =C-s= to move forth.
- =C-r= (~isearch-backward~) :: Search backward from point
(incremental); retype =C-r= to move back. While using either =C-s=
and =C-r= you can move in the opposite direction with either of
those keys when performing a repeat.
- =C-M-s= (~isearch-forward-regexp~) :: Same as =C-s= but matches a
regular expression. The =C-s= and =C-r= motions are the same after
matches are found.
- =C-M-r= (~isearch-backward-regexp~) :: The counterpart of the above
=C-M-s= for starting in reverse.
- =C-s C-w= (~isearch-yank-word-or-char~) :: Search forward for
word-at-point. Again, =C-s= and =C-r= move forth and back,
respectively.
- =C-r C-w= (~isearch-yank-word-or-char~) :: Same as above, but
backward.
- =M-s o= (~occur~) :: Search for the given regular expression
throughout the buffer and collect the matches in an =*occur*=
buffer. Also check what I am doing with this in my custom
extensions: [[#h:b902e6a3-cdd2-420f-bc99-3d973c37cd20][The =nebkor-search.el= extras provided by the =prot-search.el= library]].
- =C-u 5 M-s o= (~occur~) :: Like the above, but give it N lines of
context when N is the prefix numeric argument (5 in
this example).
- =C-s SEARCH= followed by =M-s o= (~isearch-forward~ --> ~occur~) ::
Like =C-s= but then put the matches in an *occur* buffer.
- =C-s SEARCH= followed by =C-u 5 M-s o= (~isearch-forward~ -->
~occur~) :: Same as above, but now with N lines of context (5 in
this example).
- =M-%= (~query-replace~) :: Prompt for target to replace and then
prompt for its replacement (see explanation)
- =C-M-%= (~query-replace-regexp~) :: Same as above, but for REGEXP
- =C-s SEARCH= followed by =M-%= (~isearch-forward~ --> ~query-replace~) :: Search
with =C-s= and then perform a query-replace for the following
matches.
- =C-M-s SEARCH M-%= (~isearch-forward-regexp~ -->
~query-replace-regexp~) :: As above, but regexp-aware.
- =C-s SEARCH C-M-%= (~isearch-forward~ --> ~query-replace-regexp~) :: Same
as above.
- =M-s h r= (~highlight-regexp~) :: Prompt for a face (like
~hi-yellow~) to highlight the given regular expression.
- =M-s h u= (~unhighlight-regexp~) :: Prompt for an already
highlighted regular expression to unhighlight (do it after the
above).
For starters, just learn:
- =C-s=
- =C-r=
- =M-s o=
- =M-%=
Now on to the configurations.

The first thing I want to do for Isearch, is make it more convenient
for me to match words that occur in sequence but are not necessarily
following each other. By default, we can do that with something like
=C-M-s= (~isearch-forward-regexp~) followed by =one.*two=. Though it
is inconvenient to be a regexp-aware search mode when all we want is
to just type =one two= and have the space be interpreted as
"intermediate characters" rather than a literal space. The following
do exactly this for regular =C-s= (~isearch-forward~) and =C-r=
(~isearch-backward~).

Starting with Emacs 31, buffers using ~grep-mode~ can now be edited
directly. The idea is to collect the results of a search in one place
and quickly apply a change across all or some of them. We have the
same concept with occur (=M-x occur=) as well as with Dired buffers
([[#h:1b53bc10-8b1b-4f68-bbec-165909761e43][The =nebkor-dired.el= section about ~wdired~ (writable Dired)]]).
For older versions of Emacs, we have the ~wgrep~ package by Masahiro
Hayashi. I configure it to have key bindings like those of the ~occur~
edit mode, which ~grep-edit-mode~ also uses.

#+begin_quote
Dired is probably my favourite Emacs tool. It exemplifies how I see
Emacs as a whole: a layer of interactivity on top of Unix. The ~dired~
interface wraps---and puts to synergy---standard commands like ~ls~,
~cp~, ~mv~, ~rm~, ~mkdir~, ~chmod~, and related. All while granting
access to many other conveniences, such as (i) marking files to
operate on (individually, with a regexp, etc.), (ii) bulk renaming
files by making the buffer writable and editing it like a regular
file, (iii) showing only files you want, (iv) listing the contents of
any subdirectory, such as to benefit from the bulk-renaming
capability, (v) running a keyboard macro that edits file contents
while using Dired to navigate the file listing, (vi) open files in an
external application, and more.
Dired lets us work with our files in a way that still feels close to
the command-line, yet has more powerful interactive features than even
fully fledged, graphical file managers.

I add two settings which make all copy, rename/move, and delete
operations more intuitive. I always want to perform those actions in a
recursive manner, as this is the intent I have when I am targeting
directories.
The ~delete-by-moving-to-trash~ is a deviation from the behaviour of
the ~rm~ program, as it sends the file into the virtual trash folder.
Depending on the system, files in the trash are either removed
automatically after a few days, or we still have to permanently delete
them manually. I prefer this extra layer of safety. Plus, we have the
~trashed~ package to navigate the trash folder in a Dired-like way
([[#h:2e005bd1-d098-426d-91f9-2a31a6e55caa][The =nebkor-dired.el= section about =trashed.el=]]).

As I already explained, Dired is a layer of interactivity on top of
standard Unix tools ([[#h:f8b08a77-f3a8-42fa-b1a9-f940348889c3][The =nebkor-dired.el= module]]). We can see
this in how Dired produces the file listing and how we can affect it.
The ~ls~ program accepts an =-l= flag for a "long", detailed list of
files. This is what Dired uses. But we can pass more flags by setting
the value of ~dired-listing-switches~. Do =M-x man= and then search
for the ~ls~ manpage to learn about what I have here. In short:
- =-A= :: Show hidden files ("dotfiles"), such as =.bashrc=, but omit
the implied =.= and =..= targets. The latter two refer to the
present and parent directory, respectively.
- =-G= :: Do not show the group name in the long listing. Only show
the owner of the file.
- =-F= :: Differentiate regular from special files by appending a
character to them. The =*= is for executables, the =/= is for
directories, the =|= is for a named pipe, the ~=~ is for a socket,
the =@= and the =>= are for stuff I have never seen.
- =-h= :: Make file sizes easier to read, such as =555k= instead of
=568024= (the size of =nebkor.org= as of this writing).
- =-l= :: Produce a long, detailed listing. Dired requires this.
- =-v= :: Sort files by version numbers, such that =file1=, =file2=,
and =file10= appear in this order instead of 1, 10, 2. The latter is
called "lexicograhic" and I have not found a single case where it is
useful to me.
- =--group-directories-first= :: Does what it says to place all
directories before files in the listing. I prefer this over a strict
sorting that does not differentiate between files and directories.
- =--time-style=long-iso= :: Uses the international standard for time
representation in the file listing. So we have something like
=2023-12-30 06:38= to show the last modified time.

I often have two Dired buffers open side-by-side and want to move
files between them. By setting ~dired-dwim-target~ to a ~t~ value,
we get the other buffer as the default target of the current rename or
copy operation. This is exactly what I want.
If there are more than two windows showing Dired buffers, the default
target is the previously visited window.
Note that this only affects how quickly we can access the default
value, as we can always type =M-p= (~previous-history-element~) and
=M-n= (~next-history-element~) to cycle through the minibuffer
history ([[#h:25765797-27a5-431e-8aa4-cc890a6a913a][The =nebkor-completion.el= settings for saving the history (~savehist-mode~)]]).

These are some minor tweaks that I do not really care about. The only

The ~dired-subtree~ package by Matúš Goljer provides the convenience
of quickly revealing the contents of the directory at point. We do not
have to insert its contents below the current listing, as we would
normally do in Dired, nor do we have to open it in another buffer just
to check if we need to go further.

When a buffer name is reserved, Emacs tries to produce the new buffer
by finding a suitable variant of the original name. The doc string of
the variable ~uniquify-buffer-name-style~ does a good job at
explaining the various patterns:
#+begin_example
For example, the files ‘/foo/bar/mumble/name’ and ‘/baz/quux/mumble/name’
would have the following buffer names in the various styles:
forward bar/mumble/name quux/mumble/name

Some notes on how I use beframe:
- I add ~beframe~ as a source for ~consult-buffers~.
+ This code comes from the ~beframe~ manual and lets me look at frame-specific buffers first when using ~consult-buffer~ (=M-s M-b=) ([[#h:22e97b4c-d88d-4deb-9ab3-f80631f9ff1d][The =nebkor-completion.el= settings for ~consult~]])
- I replace the default =C-x b= (~switch-to-buffer~) with the beframe'd version of the same command.
+ This lets me focus on the buffers in the current frame, which is what I generally want. When I need to access files or buffers which are not open yet, I use either:
- The consult version of the command (=M-s M-b=)
- ~project.el~ to find a file in the current project (=C-x p f=)
- When I am done with the frame, I delete all the buffers in the frame using ~beframe-kill-buffers-matching-regexp~ (=C-c b k=) with regex ~*~. This automatically kills the frame.

#+begin_quote
The built-in ~ediff~ feature provides several commands that let us
compare files or buffers side-by-side. The defaults of ~ediff~ are bad,
in my opinion: it puts buffers one on top of the other and places the
"control panel" in a separate Emacs frame. The first time I tried to
use it, I thought I broke my setup because it is unlike anything we
normally interact with. As such, the settings I have for
~ediff-split-window-function~ and ~ediff-window-setup-function~ are
what I would expect Emacs maintainers to adopt as the new default. I
strongly encourage everyone to start with them.
In my workflow, the points of entry to the ~ediff~ feature are the
commands ~ediff-files~, ~ediff-buffers~. Sometimes I use the 3-way
variants with ~ediff-files3~ and ~ediff-buffers3~, though this is rare.
Do watch the video I link to in the beginning of this section, as it
covers the main functionality of this neat tool. I also show how it

built-in =vc.el= ([[#h:50add1d8-f0f4-49be-9e57-ab280a4aa300][The =nebkor-git.el= section about =vc.el= and related]]).
We can specify more project roots as a list of strings in the user
option ~project-vc-extra-root-markers~. I work exclusively with Git
repositories, so I just add there a =.project= file in case I ever
need to register a project without it being controlled by ~git~. In
that case, the =.project= file is just an empty file in a directory
that I want to treat as the root of this project.
The common way to switch to a project is to type =C-x p p=, which
calls the command ~project-switch-project~. It lists all registered
projects and also includes a =... (choose a dir)= option. By choosing
a new directory, we register it in our project list if it has a
recognisable root. Once we select a project, we are presented with a
list of common actions to start working on the project. These are
defined in the user option ~project-switch-commands~ and are activated
by the final key that accesses them from the =C-x p= prefix. As such,
do =M-x describe-keymap= and check the ~project-prefix-map~. For
example, I bind ~project-dired~ to =C-x p RET=, so =RET= accesses this
command after =C-x p p= as well.
If any of the =project.el= commands is called from outside a project,
it first prompts for a project and then carries out its action. For
example, ~project-find-file~ will ask for a project to use, then
switch to it, and then prompt for a file inside of the specified
project.
While inside a project, we have many commands that operate on the
project level. For example, =C-x p f= (~project-find-file~) searches
for a file across the project, while =C-x p b= (~project-switch-to-buffer~)
switches to a buffer that is specific to the project. Again, check the
~project-prefix-map~ for available commands.
If not inside a project, the project-related commands will first
prompt to select a project (same as typing =C-x p p=) and then carry
out their action.
I combine projects with my ~beframe~ package, so that when I switch to
a project I get a new frame that limits the buffers I visit there
limited to that frame ([[#h:77e4f174-0c86-460d-8a54-47545f922ae9][The =nebkor-window.el= section about ~beframe~]]).

The ~magit~ package, maintained by Jonas Bernoulli, is the best
front-end to ~git~ I have ever used. Not only is it excellent at
getting the job done, it also helps you learn more about what ~git~
has to offer.
At the core of its interface is ~transient~. This is a library that
was originally developed as Magit-specific code that was then
abstracted away and ultimately incorporated into Emacs version 29.
With ~transient~, we get a window pop up with keys and commands
corresponding to them. The window is interactive, as the user can set
a value or toggle an option and have it take effect when the relevant
command is eventually invoked. For ~git~, in particular, this
interface is a genious way to surface the plethora of options.
To start, call the command ~magit-status~. It brings up a buffer that
shows information about the state of the repository. Sections include
an overview of the current =HEAD=, untracked files, unstaged changes,
staged changes, and recent commits. Each section's visibility state
can be cycled by pressing =TAB= (variations of this are available---remember
to do =C-h m= (~describe-mode~) in an unfamiliar major mode to get
information about its key bindings).
From the status buffer, we can perform all the usual version control
operations. By typing =?= (~magit-dispatch~), we bring up the main
~transient~ menu, with keys that then bring up their own submenus,
such as for viewing commit logs, setting the remotes, switching
branches, etc.

At its core, Org is a plain text markup language. By "markup
language", we refer to the use of common characters to apply styling,
such as how a word wrapped in asterisks acquires strong emphasis.
Check the video I link to above on the basics of Org mode.
Though what makes Org powerful is not the markup per se, but the fact
that it has a rich corpus of Emacs Lisp code that does a lot with this
otherwise plain text notation. Some of the headline features:
- Cycle the visibility of any heading and its subheadings. This lets
you quickly fold a section you do not need to see (or reveal the one
you care about).
- Mix prose with code in a single document to either make the whole
thing an actual program or to evaluate/demonstrate some snippets.
- Convert ("export") an Org file to a variety of formats, including
HTML and PDF.
- Use LaTeX inside of Org files to produce a scientific paper without
all the markup of LaTeX.
- Manage TODO lists and implement a concomitant methodology of
labelling task states.
- Quickly shift a "thing" (heading, list item, paragraph, ...) further
up or down in the file.
- Use tables with formulas as a lightweight alternative to spreadsheet
software.
- Capture data or fleeting thoughts efficiently using templates.
- Maintain an agenda for all your date-bound activities.
- Clock in and out of tasks, to eventually track how you are spending
your time.
- Link to files regardless of file type. This includes special links
such as to an Info manual or an email, if you also have that running
locally and integrated with Emacs ([[#h:755e195b-9471-48c7-963b-33055969b4e2][The =nebkor-email.el= module]]).
In other words, Org is highly capable and widely considered one of the
killer apps of Emacs.
This section covers the relevant configurations. You will notice that
it is not limited to Org, as some other built-in features are also
relevant here.

The ~calendar~ is technically independent of Org, though it tightly
integrates with it. We witness this when we are setting timestamps,
such as while setting a =SCHEDULED= or =DEADLINE= entry for a given
heading. All I do here is set some stylistic preferences.
Note that Emacs also has a ~diary~ command. I used it for a while, but
Org is far more capable, so I switched to it completely.

The built in =appt.el= defines functionality for handling
notifications about appointments. It is originally designed to work
with the generic diary feature (the =M-x diary= one, I mean), which I
do not use anymore, but also integrates nicely with the Org agenda
([[#h:7fe87b83-2815-4617-a5f9-d3417dd9d248][The =nebkor-org.el= Org agenda settings]]). I deepen this
integration further, such that after adding a task or changing its
state, the appointments mechanism re-reads my data to register new
notifications. This is done via a series of hooks and with the use of
the advice feature of Emacs Lisp.
Here I am setting some simple settings to keep appointment notifations
minimal. I do not need them to inform me about the contents of my next
entry on the agenda: just show text on the mode line telling me how
many minutes are left until the event.
In Org files, every heading can have an =APPT_WARNTIME= property: it takes
a numeric value representing minutes for a forewarning from =appt.el=.
I use this in tandem with ~org-capture~ for tasks that need to be
done at a specific time, such as coaching sessions ([[#h:f8f06938-0dfe-45c3-b4cf-996d36cba82d][The =nebkor-org.el= Org capture templates (~org-capture~)]]).

By default, Org looks for files in the =~/org= directory. If you want to use a location other than the default localtion for your ~org-mode~ files, set the environment variable ~ORG_DIRECTORY~.
#+begin_quote
Org, also known as "Org mode", is one of the potentially most useful
feature sets available to every Emacs user. At its core, Org is a
lightweight markup language: you can have headings and paragraphs,
mark a portion of text with emphasis, produce bullet lists, include
code blocks, and the like. Though what really sets Org apart from
other markup languages is the rich corpus of Emacs Lisp written around
it to do all sorts of tasks with this otherwise plain text format.
With Org you can write technical documents (e.g. the manuals of all my
Emacs packages), maintain a simple or highly sophisticated system for
task management, organise your life using the agenda, write tables
that can evaluate formulas to have spreadsheet functionality, have
embedded LaTeX, evaluate code blocks in a wide range of programming
languages and reuse their results for literate programming, include
the contents of other files into a singular file, use one file to
generate other files/directories with all their contents, and export
the Org document to a variety of formats like =.pdf= and =.odt=.
Furthermore, Org can be used as a lightweight, plain text database, as
each heading can have its own metadata. This has practical
applications in most of the aforementioned.
In short, if something can be done with plain text, Org probably does
it already or has all the elements for piecing it together. This
document, among many of my published works, is testament to Org's
sheer power, which I explained at greater length in a video
demonstration: [[https://protesilaos.com/codelog/2023-12-18-emacs-org-advanced-literate-conf/][Advanced literate configuration with Org]] (2023-12-18).
This being Emacs, everything is customisable and Org is a good example
of this. There are a lot of user options for us to tweak things to our
liking. I do as much, though know that Org is perfectly usable without
any configuration. The following sections contain further commentary
on how I use Org.

#+begin_quote
One of the many use-cases for Org is to maintain a plain text to-do
list. A heading that starts with a to-do keyword, such as =TODO= is
treated as a task and its state is considered not completed.
We can switch between the task states with shift and the left or right
arrow keys. Or we can select a keyword directly with =C-c C-t=, which
calls ~org-todo~ by default. I personally prefer the latter approach,
as it is more precise.
Whenever a task state changes, we can log that event in a special
=LOGBOOK= drawer. This is automatically placed right below the
heading, before any paragraph text. Logging data is an opt-in feature,
which I consider helpful ([[#h:0884658e-9eb5-47e3-9338-66e09004a1a0][The =nebkor-org.el= Org time/state logging]]).
Tasks can be associated with timestamps, typically a scheduled
date+time or a deadline+time. This can be helpful when we are
reviewing the source Org file, though it really shines in tandem with
the agenda. Any heading that has a timestamp and which belongs to a
file in the ~org-agenda-files~ will show up on the agenda in the given
date ([[#h:7fe87b83-2815-4617-a5f9-d3417dd9d248][The =nebkor-org.el= Org agenda settings]]).
By default, the ~org-todo-keywords~ are =TODO= and =DONE=. We can
write more keywords if we wish to implement a descriptive workflow.
For example, we can have a =WAIT= keyword for something that is to be
done but is not actionable yet. While the number of keywords is not
limited, the binary model is the same: we have words that represent
the incomplete state and those that count as the completion of the
task. For instance, both =CANCEL= and =DONE= mean that the task is not
actionable anymore and we move on to other things. As such, the extra
keywords are a way for the user to make tasks more descriptive and
easy to find. In the value of the ~org-todo-keywords~, we use the bar
character to separate the incomplete state to the left from the
completed one to the right.
One of the agenda's headiline features is the ability to produce a
view that lists headings with the given keyword. So having the right
terms can make search and retrieval of data more easy. On the
flip-side, too many keywords add cognitive load and require more
explicit search terms to yield the desired results. I used to work
with a more descriptive set of keywords, but ultimately decided to
keep things simple.
The refile mechanism is how we can reparent a heading, by moving it
from one place to another. We do this with the command ~org-refile~,
bound to =C-c C-w= by default. A common workflow where refiling is
essential is to have an "inbox" file or heading, where unprocessed
information is stored at, and periodically process its contents to
move the data where it belongs. Though it can also work fine without
any such inbox, in those cases where a heading should be stored
someplace else. The ~org-refile-targets~ specifies the files that are
available when we try to refile the current heading. With how I set it
up, all the agenda files plus the current file's headings up to level
2 are included as possible targets.
In terms of workflow, I have not done a refile in a very long time,
because my entries always stay in the same place as I had envisaged at
the capture phase ([[#h:f8f06938-0dfe-45c3-b4cf-996d36cba82d][The =nebkor-org.el= Org capture templates (~org-capture~)]]).

Each Org heading can have one or more tags associated with it, while
all headings inherit any potential =#+FILETAGS=. We can add tags to a
heading when the cursor is over it by typing the ever flexible =C-c C-c=.
Though the more specific ~org-set-tags-command~ also gets the job
done, plus it does not require that the cursor is positioned on the
heading text.
Tagging is useful for searching and retrieving the data we store. The
Org agenda, in particular, provides commands to filter tasks by tag:
- [[#h:024dd541-0061-4a10-b10b-b17dcd4794b9][The =nebkor-org.el= Org to-do and refile settings]]

Org can keep a record of state changes, such as when we set an entry
marked with the =TODO= keyword as =DONE= or when we reschedule an
appointment ([[#h:7fe87b83-2815-4617-a5f9-d3417dd9d248][The =nebkor-org.el= Org agenda settings]]). This data
is stored in a =LOGBOOK= drawer right below the heading. I choose to
keep track of this information, as it is sometimes useful to capture
mistakes or figure out intent in the absence of further clarification
(though I do tend to write why something happened).

One of the nice things about Org is its flexible linking mechanism. It
can produce links to a variety of file types or buffers and even
navigate to a section therein.
At its simplest form, we have the =file= link type, which points to a
file system path, with an optional extension for a match inside the
file, as documented in the manual. Evaluate this inside of Emacs:
#+begin_example emacs-lisp
(info "(org) Search Options")
#+end_example
#+end_quote
I bind ~org-store-link~ in main section of the Org configuration:
[[#h:e03df1e0-b43e-49b5-978e-6a511165617c][The =nebkor-org.el= section with basic Org settings]].

More generally, Org is capable of evaluating code blocks and passing
their return value to other code blocks. It is thus possible to write
a fully fledged program as an Org document. This paradigm is known as
"literate programming". In the case of an Emacs configuration, such as
mine, it is called a "literate configuration" or variants thereof. I
did a video about my setup: [[https://protesilaos.com/codelog/2023-12-18-emacs-org-advanced-literate-conf/][Advanced literate configuration with Org]] (2023-12-18).
Org can evaluate code blocks in many languages. This is known as "Org
Babel" and the files which implement support for a given language are
typically named =ob-LANG.el= where =LANG= is the name of the language.
We can load the requisite code for the languages we care about with
something like the following:
#+begin_example emacs-lisp
(require 'ob-python)
;; OR
(use-package ob-python)
;; OR for more control
(use-package ob-python
:after org
:config

The ~org-capture~ command allows us to quickly store data in some
structured way. This is done with the help of a templating system
where we can, for example, record the date the entry was recorded,
prompt for user input, automatically use the email's subject as the
title of the task, and the like. The documentation string of
~org-capture-templates~ covers the technicalities.

The built-in ~show-paren-mode~ highlights the parenthesis on the
opposite end of the current symbolic expression. It also highlights
matching terms of control flow in programming languages that are not
using parentheses like Lisp: for instance, in a ~bash~ shell script it
highlights the ~if~ and ~fi~ keywords. This mode also works for prose
and I use it globally. Simple and effective!

The built-in ~eldoc~ feature is especially useful in programming
modes. While we are in a function call, it produces an indicator in
the echo area (where the minibuffer appears upon invocation) that
shows the name of the function, the arguments it takes, if any, and
highlights the current argument we are positioned at. This way, we do
not have to go back to review the signature of the function just to
remember its arity. Same principle for variables, where ~eldoc-mode~
puts the first line of their documentation string in the echo area.

The built-in ~eglot~ feature, developed and maintained by João Távora,
is Emacs' own client for the Language Server Protocol (LSP). The LSP
technology is all about enhancing the ability of a text editor to work
with a given programming language. This works by installing a
so-called "language server" on your computer, which the "LSP client"
(i.e. ~eglot~) will plug into. A typical language server provides the
following capabilities:
- Code completion :: This can be visualised for in-buffer
automatic expansion of function calls, variables, and the like
([[#h:804b858f-7913-47ef-aaf4-8eef5b59ecb4][The =nebkor-completion.el= for in-buffer completion popup (~corfu~)]]).
- Code linting :: To display suggestions, warnings, or errors. These
are highlighted in the buffer, usually with an underline, and can
also be displayed in a standalone buffer with the commands
~flymake-show-buffer-diagnostics~, ~flymake-show-project-diagnostics~
([[#h:df6d1b52-0306-4ace-9099-17dded11fbed][The =nebkor-langs.el= settings for code linting (~flymake~)]]).
- Code navigation and cross-referencing :: While over a symbol, use a
command to jump directly to its definition. The default key bindings
for going forth and then back are =M-.= (~xref-find-definitions~)
and =M-,= (~xref-go-back~).
...
Assuming the language server is installed, to start using the LSP
client in a given file, do =M-x eglot=. To make this happen
automatically for every newly visited file, add a hook like this:
(add-hook 'SOME-MAJOR-mode #'eglot-ensure)
#+end_quote
I use ~eglot~ as the main LSP entry point, and as such, I have key-bindings for the common functionality implemented by ~eglot~.
Note that demanding ~eglot~ is not a mistake. I want it loaded so that I can advice functions for different programming langauges. For example, Python uses ~emacs-pet~ for tracking the environment of each project, and this needs to load after ~eglot~ so that it can advice the necessary functions.

The built-in ~flymake~ feature defines an interface for viewing the
output of linter programs. A "linter" parses a file and reports
possible notes/warnings/errors in it. With ~flymake~ we get these
diagnostics in the form of a standalone buffer as well as inline
highlights (typically underlines combined with fringe indicators) for
the portion of text in question. The linter report is displayed with
the command ~flymake-show-buffer-diagnostics~, or ~flymake-show-project-diagnostics~.
Highlights are shown in the context of the file.
The built-in ~eglot~ feature uses ~flymake~ internally to handle the
LSP linter output ([[#h:92258aa8-0d8c-4c12-91b4-5f44420435ce][The =nebkor-langs.el= settings for ~eglot~]]).
As for what I have in this configuration block, the essentials for me
are the user options ~flymake-start-on-save-buffer~ and ~flymake-start-on-flymake-mode~
as they make the linter update its report when the buffer is saved and
when ~flymake-mode~ is started, respectively. Otherwise, we have to
run it manually, which is cumbersome.
The ~package-lint-flymake~ package by Steve Purcell adds the glue code
to make ~flymake~ report issues with Emacs Lisp files for the purposes
of packaging. I use it whenever I work on my numerous Emacs packages.

The built-in Python mode for Emacs goes a long way. I use the
following stack when programming Python:
- =uv= for package and venv management
- =pylsp= as the language server
- =ruff= as the linting and formatting tool
Run the following commands in every virtualenv environment to setup
the necessary developer tooling:
- =uv add ruff python-lsp-server python-lsp-ruff --group dev=
+ Ruff is an extremely fast Python linter, and code formatter,
written in Rust. Ruff is also a langauge server, but it only
provides functionality related to formating and linting. As it
adds more over time (like go-to definition), I may make it my
primary language server
+ Python LSP Server (provides the binary ~pylsp~) is the defacto
language server for Python.
+ =python-lsp-ruff= provides tight integration between ~pylsp~ and
~ruff~, enabling the language server to use ruff for it's linting
and formatting capabilities.
- =uv add pytest --group dev=
Uv takes care of setting up the venv properly, so if you replace the
default commands with uv versions, you are good to go. In practice,
this means:
- Use ~C-u C-c C-p~ command (=run-python=, with an argument) to start
the Inferior Python Shell, instead of ~C-c C-p~.
- This will prompt you for a command, with the default value being
=python3 -i=. Change it to =uv run python3 -i=.
- Modify the ~C-c C-v~ command (=python-check=) to:
=uv run ruff check <filename>=
NOTE: Exactly the same instructions also work for Poetry, just replace
~uv~ with ~poetry~ in any of the commands above.

Denote is my goto tool for any and all note-taking. This is what
powers my brain forest, and where anything and everything I write
starts from.
By default, Denote looks for files in the =~/Documents/notes/=
directory. If you want to use a location other than the default
localtion for your ~denote~ files, set the environment variable
~DENOTE_DIRECTORY~.
#+begin_quote
This is another one of my packages and is extended by my
~consult-denote~ package ([[#h:ee82e629-fb05-4c75-9175-48a760a25691][The =nebkor-study.el= integration between Consult and Denote (~consult-denote~)]]).
Denote is a simple note-taking tool for Emacs. It is based on the idea
that notes should follow a predictable and descriptive file-naming
scheme. The file name must offer a clear indication of what the note is
about, without reference to any other metadata. Denote basically
streamlines the creation of such files while providing facilities to
link between them.
Denote's file-naming scheme is not limited to "notes". It can be used
for all types of file, including those that are not editable in Emacs,
such as videos. Naming files in a consistent way makes their
filtering and retrieval considerably easier. Denote provides relevant
facilities to rename files, regardless of file type.

~toc-org~ is a simple and nifty package for automatically creating a
table of contents in any ~org-mode~ file. It works by
creating/updating a table of contents under the first heading with the
tag =:TOC:=.
By default, it creates a version of links which export according to
the format expected by Github (so that the links work correctly for
someone reading on Github). But these links don't work in standard
~org-mode~ (without ~toc-org~ enabled).
Enabling ~toc-org-mode~ in the org file means that anytime I save the
buffer, the TOC will automatically be updated. Also, the links created
in the TOC will be navigable using standard ~org-mode~ shortcuts.
To enable ~toc-org~, run =M-x toc-org-mode= in your ~org-mode~ file
and create a heading with the tag =:TOC:= added to it.

I want this section to contain all the personal configuration that
anyone using this repo should modify. But I don't know how to do this
properly at the moment, in a way such that it's part of the repo, and
yet only exported for me. I'll update this section as and when I
figure it out.
