* 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:

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

#+RESULTS:
| 20240727 |
| 20240727 |

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

* 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
  ;; 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*.
  ;;
#+END_SRC

Also immediately set lexical binding mode.
** Set the garbage collector threshold, to avoid collections

The emacs history goes back to times where memory was counted in
bytes, not gigabytes. We can afford to be a bit more generous with the
garbage collector settings.

#+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)
    "Report the time since the file was init script was started.

  If SUFFIX is provided, it is appended to the message."
    (message "%.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)
  (report-time-since-load "start init file")
#+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

*** Load the General

Needs to load early so the ~:general~ keyword is available for ~use-package~.

#+BEGIN_SRC emacs-lisp
  (use-package general
    :ensure t
    :demand t)
#+END_SRC


*** Enable Undo Tree
undo-tree is my preferred way of undoing and redoing stuff. The main reason is it doesn’t create a linear undo/redo history, but rather a complete tree you can navigate to see your complete editing history. One of the two obvious things to do are to tell Emacs to save all its undo history fies in a dedicated directory, otherwise we’d risk littering all of our directories. The second thing is to simply globally enable its mode.

(use-package undo-tree
  :defer t
  :straight (:build t)
  :custom
  (undo-tree-history-directory-alist
   `(("." . ,(expand-file-name (file-name-as-directory "undo-tree-hist")
                               user-emacs-directory))))
  :init
  (global-undo-tree-mode)
  :config
  <<undo-tree-ignore-text-properties>>
  <<undo-tree-compress-files>>
  (setq undo-tree-visualizer-diff       t
        undo-tree-auto-save-history     t
        undo-tree-enable-undo-in-region t
        undo-limit        (* 800 1024)
        undo-strong-limit (* 12 1024 1024)
        undo-outer-limit  (* 128 1024 1024)))




** Utility Functions


*** Reload dir local variables

#+BEGIN_SRC emacs-lisp
(defun pti-reload-dir-locals-for-current-buffer ()
  "Reload dir locals for the current buffer."
  (interactive)
  (let ((enable-local-variables :all))
    (hack-dir-local-variables-non-file-buffer)))
#+END_SRC

#+RESULTS:
: pti-reload-dir-locals-for-current-buffer


** 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.

#+BEGIN_SRC emacs-lisp
  (require 'url)
  (defun pti-latest-github-release (repo)
    "Return the latest version of the releases for REPO.

              The repo should be in the form of `owner/repo'."
    (with-temp-buffer
        (url-insert-file-contents
         (format "https://api.github.com/repos/%s/releases/latest" repo))
      (let ((result (json-read)))
        (cdr (assoc 'name result)))))
#+END_SRC

#+RESULTS:
: pti-latest-github-release

#+BEGIN_SRC emacs-lisp :tangle no :results value
  (pti-latest-github-release "plantuml/plantuml")
#+END_SRC

#+RESULTS:
: v1.2024.6

* Crafted Emacs

#+BEGIN_SRC emacs-lisp
(report-time-since-load "Crafted Emacs")
#+END_SRC


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)

(report-time-since-load "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:
: pti-org-config

* Integration with Environment

#+BEGIN_SRC emacs-lisp
(report-time-since-load "Integration with Environment")
#+END_SRC

** 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

              (edit-server-start)
            (add-hook 'after-init-hook
                      #'(lambda() (edit-server-start))))
    :config (setq edit-server-new-frame-alist
                  '((name . "Edit with Emacs FRAME")
                    (top . 200)
                    (left . 200)
                    (width . 80)
                    (height . 25)
                    (minibuffer . t)
                    (menu-bar-lines . t)
                    (window-system . x))))

It is very useful to create for each active project a custom JQL to
make a snapshot of issues just for that project in the folder of the
project to keep everything in context.

- update issues in background when opening the project.
- run custom JQL defined in the project iso globally.

**** 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.

stop the repl threads before saving the image like the following:

*** 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 :tangle no
  (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")))
#+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...

*** Integrate ERC with i3 Desktops

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

This is no longer useful : I seldom use i3, but it is useful for
inspiration

#+BEGIN_SRC emacs-lisp :tangle no
  (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")
      (report-time-since-load "Waiting to connect to IRC...")
      (dotimes (i 12)
        (unless (member channel (mapcar 'buffer-name (erc-channel-list nil)))
          (sleep-for 0.25)))
      (set-window-buffer
       (frame-selected-window frame) channel)))

*** TODO OPML To Elfeed

#+BEGIN_SRC emacs-lisp
    (use-package opml-to-elfeed-feeds

#+END_SRC

#+RESULTS:

This does all kind of weird things. Apparently elpaca or use-package
magically namespaces all the functions and for some reason it fails
to require 'elfeed'. ... The weird thing is that the emacs lips
feature is used to expand o2e to opml-to-elfeed-feeds, by setting the
`read-symbol-shorthands` variable to `(("o2e"
. "opml-to-elfeed-feeds"))`.

Agreed with cow_2000 to create an issue on the repo with my
recommendation for public API.


** Enable 0x0 to share snippets and files easily
Configures the ~0x0~ package for easily sharing code snippets and files:
#+BEGIN_SRC emacs-lisp
  ;; configure 0x0
  (use-package 0x0
    :ensure t
    :config (setq 0x0-use-curl t))
#+END_SRC

#+RESULTS:
: [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.

** 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.
