#+TITLE: My Emacs Configuration
#+PROPERTY: header-args :tangle yes
* Literate Configuration for Emacs
** Goals
- Manage *init.el* as an org-file
- Use a simple robust tangling solution which works together with
Crafted Emacs
- Leverage inclusion of ~use-package~ in Emacs29 for configuration and
loading
- Reduce dependencies : read evaluate the value a package brings
before including it
- Refactor existing configuration
* First Things First
*** Make tangled file read-only
Add a preamble to the file to ensure some global settings, most
importantly make the file read-only to avoid editing the tangled file by
accident instead of the source in the org-mode file.
#+BEGIN_SRC emacs-lisp
;;; -*- lexical-binding: t; read-only-mode: t; -*-
;;
;; DO NOT EDIT!!!
;;
;; This file is automatically generated from the source in *init.org*.
;;
#+END_SRC
Also immediately set lexical binding mode.
** Set the garbage collector threshold, to avoid collections
#+begin_src emacs-lisp
(setq gc-cons-percentage 0.5
gc-cons-threshold (* 128 1024 1024))
#+end_src
** Report time spent loading the configuration
#+begin_src emacs-lisp
(defconst emacs-start-time (current-time))
(defun report-time-since-load (&optional suffix)
(message "Loading init... (%.3fs) %s"
(float-time (time-subtract (current-time) emacs-start-time))
suffix))
(add-hook 'after-init-hook
#'(lambda () (report-time-since-load " [after-init]"))
t)
#+end_src
When looking for where the time goes, the `report-time-since-load`
with a string indicating the location in the init process can report
on the time since start.
*** Save customizations in a separate file
By default customization settings are saved at the end of the *init.el*
file. This wreaks havoc with managing the files in git and will not
work with the tangled version anyway as it will be removed/overwritten
each time the file is regenerated.
Here we set the location of the file to save the customizations and
then load it.
#+BEGIN_SRC emacs-lisp
;;; Code:
(setq custom-file (concat user-emacs-directory "custom.el"))
(when (and custom-file
(file-exists-p custom-file))
(load custom-file nil :nomessage))
#+END_SRC
** Crafted Emacs
When I could not solve the persistent slowness I experienced on
Windows using Doom Emacs, I wanted to switch to a more hands-on
minimal Emacs configuration. I just watched the 'Rational Emacs'
episode and that seemed as good a starting point as any. Then in
August '22 it was renamed to Crafted Emacs which prompted a
(minor) refactoring.
I used for a quite a long term Doom on Linux and Rational/Crafted on
Windows till I was comfortable enough and not started Doom anymore.
*** Initialize Crafted Emacs
Loads the Crafted Emacs initialization configuration:
#+BEGIN_SRC emacs-lisp
;; initialize crafted-emacs
(setq crafted-startup-inhibit-splash t)
(load "~/.local/share/crafted-emacs/modules/crafted-init-config")
#+END_SRC
*** Add and configure packages and load crafted and custom modules
Lists and installs a variety of packages and includes custom configurations for them:
#+BEGIN_SRC emacs-lisp
(require 'crafted-completion-packages)
(require 'crafted-evil-packages)
(require 'crafted-lisp-packages)
(require 'crafted-writing-packages)
(require 'crafted-ui-packages)
(message "loading packages")
(crafted-package-install-selected-packages)
(elpaca-wait)
(require 'crafted-defaults-config)
(require 'crafted-evil-config)
(require 'crafted-completion-config)
(require 'crafted-org-config)
(require 'crafted-lisp-config)
(require 'crafted-writing-config)
(require 'crafted-ui-config):
#+END_SRC
#+RESULTS:

** Integration with Environment
*** Set default Coding System to Use UTF-8 Everywhere
Ensures UTF-8 is the default coding system everywhere.
#+BEGIN_SRC emacs-lisp
(set-default-coding-systems 'utf-8)
(set-language-environment 'utf-8)
(setq locale-coding-system 'utf-8)
(prefer-coding-system 'utf-8)
;; Treat clipboard input as UTF-8 string first; compound text next, etc.
(setq x-select-request-type '(UTF8_STRING COMPOUND_TEXT TEXT STRING))
#+END_SRC
Here’s a breakdown of what each line does:
1. *(set-default-coding-systems 'utf-8)*
This line sets the default coding system for new buffers. When you
create a new buffer or open a file, Emacs will use UTF-8 encoding
by default. It will also set the default terminal and keyboard
coding systems. This applies to all internal operations where a
specific coding system has not been specified.
2. *(set-language-environment 'utf-8)*
This sets the language environment to UTF-8. Emacs uses the
language environment to guess the preferred coding systems for
reading and writing files and for other operations. Setting this to
UTF-8 ensures that UTF-8 is preferred in all language-related
contexts.
3. *(setq locale-coding-system 'utf-8)*
This sets the coding system for locale data, such as environment
variables and system messages. It ensures that Emacs correctly
interprets UTF-8 encoded data coming from the operating system.
4. *(prefer-coding-system 'utf-8)*
This makes UTF-8 the preferred coding system for any situation
where Emacs needs to choose an encoding. It ensures that Emacs
prefers UTF-8 over other encodings.
5. *(setq x-select-request-type ...)*
Treat clipboard input as UTF8_STRING first, compound text next,
etc... .
*** Set Path from shell configuration
In order to get the paths in Emacs to be consistent with the ones in
the terminals we get them from a started shell instead of the current
environment which can be considerably different in X, Wayland or on
Mac because the shell initialization scripts have not run yet.
#+BEGIN_SRC emacs-lisp
;; set path from shell when started in UI-RELATED
(use-package exec-path-from-shell
:ensure t
:defer 1
:if (or (daemonp) (memq window-system '(mac ns x)))
:config (exec-path-from-shell-initialize))
#+END_SRC
*** Setup backup directories
Configures where backup files are stored:
#+BEGIN_SRC emacs-lisp
;; setup backup directories
;; see https://www.emacswiki.org/emacs/BackupDirectory
(setq backup-directory-alist
`(("." . ,(file-name-concat user-emacs-directory "backups"))))
#+END_SRC
*** Enable integration with the Unix Password Store aka *pass*
The *pass* command gives a super practical way to store secrets
encrypted using *gpg* and use them in *.envrc* files, batch scripts on the
command line and, of course, in *Emacs*.
#+BEGIN_SRC emacs-lisp
;; enable unix password-store
;;(use-package epg)
;;(setq epg-pinentry-mode 'loopback)
(auth-source-pass-enable)
#+END_SRC
This enables *pass* secrets to be used for all subsystems supporting
*auth-source* (which are probably all of them nowadays). It does require
some finagling to map the parts on the name in the pass system.
- [[https://www.passwordstore.org/][Pass Website]]
- [[info:auth#The Unix password store][auth#The Unix password store in the info pages]]
**** Use of Pass Secrets in ELisp
It is very convenient to get secrets from this store (once gpg is set
up, which a totally different can of worms). A function
`auth-source-pass-get` is provided :
#+BEGIN_SRC emacs-lisp :tangle no
(auth-source-pass-get 'secret "dummy/password")
#+END_SRC
#+RESULTS:
: shht!secret
*** GUIX support
[[https://gitlab.com/emacs-guix/emacs-guix][Emacs-guix]] is a module to interact with the guix system and help
manage packages and profiles. It also offers support for creating
additional profiles and packages for Guix.
#+BEGIN_SRC emacs-lisp
(use-package guix
:ensure t
:defer 5)
#+END_SRC
I find it a bit a confusing module.
It provides a minor-mode

***** Treesitter Grammars for Windows
Windows does not come with a handy-dandy C-compiler available as *cc* or *gcc* or even *c99* and treesitter does not have a handy dandy feature to remap that to *zig cc* and similar.
However we can download it from the release page of the tree-sitter-langs repo or even better install the *tree-sitter-langs* package.
This will download the dynamic library to _user-emacs-directory_/elpa/tree-sitter-langs/bin
However they'll have the wrong filename and are not in the path where treesitter looks in.
- Open the folder with *dired*
- switch to writable with `C-xC-q` to enable *wdired*
- :%s/[a-z-]\*.dll/libtree-sitter-\\0/
- `C-cC-c` to confirm the changes if it looks ok
- `%m` to mark all files starting with libtree
- `R` them to the *~/.config/emacs/tree-sitter* folder
and they will now be installed.
Normally that should work for other OSes too, but there is no real need for it.

Setup all channels which are joined by default.
**** ERC connect function
Define a function to login to ERC when needed. In principle ERC
reconnects after suspend, and sometimes it even works, but mostly I
run this function again to reconnect, which will update the buffers
with the rooms I joined.
#+BEGIN_SRC emacs-lisp
(defun snam-erc ()
"Login to znc bouncer and join rooms."
(interactive)
(erc-tls :id 'znc
:server (auth-source-pass-get "server" "snamellit/znc")

:user (auth-source-pass-get "user" "snamellit/znc")
:nick (auth-source-pass-get "nick" "snamellit/znc")
:password (auth-source-pass-get 'secret "snamellit/znc")))
#+END_SRC
#+RESULTS:
: snam-erc
In practice this has proven to be a very useful function to reconnect
in all kind of weird situation.
***** TODO Figure out how to make ERC reconnect more reliably
Although running `snam-erc` is not a big deal, it should not be needed
so much. I should figure out in what cases reconnects fail or dropping
connections fail to be recognized.
I often see that ERC is _reconnecting_ however this seems to silently
fail. I dunno, there is something fishy here...

The commands this package offers:
- ~0x0-dwim~ chooses the right one of the following, based on location or previous commands.
- ~0x0-upload-text~ will upload the active region or if not existent the entire buffer
- ~0x0-upload-file~ will upload a selected file
- ~0x0-upload-kill-ring~ uploads the content of the kill ring
- ~0x0-popup~ creates and displays a buffer, lets you upload its contents later
- ~0x0-shorten-uri~ prompts for a uri, shortens it
IMSMR the shorten-uri functionality is disabled in the 0x0 service
as apparently is was abused too much.
