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

Notes on Elpaca and dev versions of emacs.

Elpaca needs the build date of emacs to compare to package versions or something. However it does not support all dev versions.

For guix emacs-next packages you can find the date with: ( <C-c C-c> in the source block below:

stat /gnu/store/*emacs-next-[23]*.drv | rg Birth | cut -d' ' -f3 | tr -d '-'

20240727

It is possible there are more so probably the most recent one is the one to use.

Inspiration Sources

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.

  ;; init.el --- Literate configuration for Emacs -*- lexical-binding: t; read-only-mode: t; -*-
  ;;
  ;;; Commentary:
  ;;
  ;; DO NOT EDIT!!!
  ;;
  ;; This file is automatically generated from the source in *init.org*.
  ;;

Also immediately set lexical binding mode.

Set the garbage collector threshold, to avoid collections

(setq gc-cons-percentage 0.5
      gc-cons-threshold (* 128 1024 1024))

Report time spent loading the configuration

  (defconst emacs-start-time (current-time))

  (defun report-time-since-load (&optional suffix)
    "Report the time since the file was init script was started.

  If SUFFIX is provided, it is appended to the message."
    (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)

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.

  ;;; Code:
  (setq custom-file (concat user-emacs-directory "custom.el"))
  (when (and custom-file
             (file-exists-p custom-file))
    (load custom-file nil :nomessage))

Utility Functions

Get latest version of a github released project

Many projects nowadays use github to release their software. However there is no easy way to get the latest version of a project provided. This functions uses the releases API to get the latest metadata and get the version number from the JSON.

  (defun pti-with-latest-github-version (repo f)
    "Return the latest version of the releases for REPO.

              The repo should be in the form of 'owner/repo'. The function F
  will be called with the version in format 'vX.Y.Z' as the only argument."
    (url-retrieve
     (format "https://api.github.com/repos/%s/releases/latest" repo)
     (lambda (events)
       (message "Events: %s" events)
       (goto-char url-http-end-of-headers)
       (let ((json-object-type 'plist)
             (json-key-type 'symbol)
             (json-array-type 'vector))
         (let ((result (json-read)))
           (message "Latest version: %s" (plist-get result 'name))
           (funcall f (plist-get result 'name))
           )))))

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:

;; initialize crafted-emacs
(setq crafted-startup-inhibit-splash t)
(load "~/.local/share/crafted-emacs/modules/crafted-init-config")

Add and configure packages and load crafted and custom modules

Lists and installs a variety of packages and includes custom configurations for them:

(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):

Integration with Environment

Set default Coding System to Use UTF-8 Everywhere

Ensures UTF-8 is the default coding system everywhere.

  (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))

Here’s a breakdown of what each line does:

(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.
(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.
(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.
(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.
(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.

    ;; 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))

Setup backup directories

Configures where backup files are stored:

  ;; setup backup directories
  ;; see https://www.emacswiki.org/emacs/BackupDirectory
  (setq backup-directory-alist
   `(("." . ,(file-name-concat user-emacs-directory "backups"))))

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.

  ;; enable unix password-store
  ;;(use-package epg)
  ;;(setq epg-pinentry-mode 'loopback)
  (auth-source-pass-enable)

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.

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 :

(auth-source-pass-get 'secret "dummy/password")

shht!secret

GUIX support

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.

    (use-package guix
      :ensure t
      :defer 5)

I find it a bit a confusing module.

It provides a minor-mode

Add a fully featured terminal emulator

  (use-package eat

Editor Features

Evil Vim Keybindings

I configure all my apps to use vim keybindings if possible to maximise muscle memory.

Yasnippet configuration

Enables and configures Yasnippet, a template system for Emacs:

    (yas-global-mode 1))

Enable LLM access with Ellama

Configures access to language models using Ellama. I don't know whether to put it under writing, comms or programming as it is equally useful(?) for either activity. So I promoted it to an Editor feature.

  (use-package llm
    :ensure t
    :commands (llm-chat llm-ask-about llm-ask-line llm-ask-selection)
    )
  (use-package llm-openai
    :ensure nil
    :commands (make-llm-openai)
    :after llm)
  ;; enable LLM access with ellama
  (use-package ellama
    :ensure t
    :commands (ellama-chat ellama-ask-about ellama-ask-line ellama-ask-selection)
    :custom
    (ellama-language "English")
    (ellama-keymap-prefix "<leader>a")
    (ellama-provider
            (make-llm-openai
             :key (auth-source-pass-get 'secret "snamellit/openai-api-key")
             :chat-model "gpt-4o"
             ))
    (ellama-sessions-directory (expand-file-name "~/Dropbox/ellama-sessions"))
    :config
    (message "Ellama is available"))

It seems the gpt-4o model provides better responses. I should investigate local models more.

Enable Direnv Integration

Direnv is the key to have isolated project folders which maintain their own bubble to support whatever is done in that folder.

set environment variables
run prep scripts or start services
load nix or guix profiles to provide support applications

Emacs' direnv module gives first class support to Emacs projects so they use the right tools for the project.

  ;; enable direnv mode
  (use-package direnv
    :ensure t
    :config
    (direnv-mode))

This enables direnv globally.

Org Babel Support

I have a test file which has samples of babel features for easy testing in my org babel test file.

Support REST calls in Babel Blocks

  ;; enable verb package to do REST calls
  (use-package verb
    :ensure t
    :defer 3
    :bind
    (:map org-mode-map
                ("C-c C-r" . verb-command-map)))

  (use-package ob-verb
    :after verb

Support Mermaid Diagrams in Babel Blocks

  ;; enable mermaid for org-babel
  (use-package ob-mermaid
    :ensure t
    :defer 3)

Mermaid needs support of the mermaid-cli which is a node package. It can be installed with

npm install -g @mermaid-js/mermaid-cli

Support PlantUML Diagrams in Babel Blocks

Requires nothing special, other than plantuml.jar archive installed.

The following code block depends on Get latest version of a github released project utility function. This block will check if there is a plantuml.jar in the emacs config directory and if not download the latest version from github. The `pti-download-latest-plantuml` is made interactive to manually install the latest version if needed.

      (defun pti-download-latest-plantuml ()
        "Download the latest version of PlantUML.

        This function is interactive to make it easy to upgrade to
      the latest, current version with `M-x pti-download-latest-plantuml'."
        (interactive)
        (pti-with-latest-github-version

TODO decide whether to keep using treesitter-auto at all or just plain treesit with some support functions.

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.

evil-paredit relies on an obsolete (and no longer available method) `evil-called-interactively-p`. So I define it here till evil-paredit has implemented the new method.

(defmacro evil-called-interactively-p ()
  "Wrapper for `called-interactively-p'.

no arguments.  In Emacs 23.2 and newer, it takes one argument."

Communication and Interwebs

ERC configuration

Set up ERC, an IRC client for Emacs, to automatically join specific channels and log in:

  (use-package erc
    :ensure t
    :defer 5
    :config
    (erc-services-mode 1)
    (erc-autojoin-mode 1)
    (erc-update-modules)
    (setq erc-autojoin-channels-alist
          '(('znc
             "#emacs" "#erc" "#spritely" "#guix"
             "#systemcrafters" "#systemcrafters-guix" "#systemcrafters-emacs"))))

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.

  (defun snam-erc ()
    "Login to znc bouncer and join rooms."
    (interactive)
    (erc-tls :id 'znc
             :server (auth-source-pass-get "server" "snamellit/znc")
             :port (auth-source-pass-get "port" "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")))

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…

Integrate ERC with i3 Desktops

I like to have my IRC channels on workspace 5 in i3.

  (defun my-erc ()
    "Create new frame and move to ws5 and launch erc."
    (interactive)
    (let ((frame (make-frame))
          (channel "#systemcrafters"))
      (call-process "i3" nil nil nil "move window to workspace 5")
      (snam-erc)
      (call-process "i3" nil nil nil "workspace 5")
      (message "Waiting to connect to IRC...")
      (dotimes (i 12)
        (unless (member channel (mapcar 'buffer-name (erc-channel-list nil)))
          (sleep-for 0.25)))

Elfeed configuration

Configures Elfeed, an RSS feed reader for Emacs:

Enable 0x0 to share snippets and files easily

Configures the 0x0 package for easily sharing code snippets and files:

  ;; configure 0x0

[nil 26279 35497 183387 nil elpaca-process-queues nil nil 963000 nil]

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.

Finishing Touches

Tell the module system that init.el is available

Indicates the init.el file is provided by and ends here:

  (provide 'init)
  ;;; init.el ends here

Future

TODO Decide about general keybindings.

The general package offers enhanced support for evil keybindings, notably it integrates with use-package to define keybindings which will load the package if not loaded yet. It considerably streamlines managing evil bindings so it should offer enough value but I just removed it, so it'll have to wait a bit.

TODO Add support for zola blogposts writing in org-mode

see ox-zola for exporting org-mode to zola markdown.

Final Words

This is the end of the configuration file.

Add a variable so the file is tangling itself each time it is saved.
