Let’s configure Emacs using Org mode, they said.  It’ll be fun, they said.


# Pave the way


## Correct `exec-path`

    (let ((win-downloads "c:/Users/aduckworth/Downloads"))
      (dolist (path (list ;; Linux
    		 (expand-file-name "bin"
    				   user-emacs-directory)

    		 ;; Windows
    		 (expand-file-name "emacs/bin"
    				   win-downloads)
    		 (expand-file-name "PortableGit/bin"
    				   win-downloads)

## Package management


### Straight.el

This still doesn’t work under Windows – I have to manually download the [repo archive](https://github.com/raxod502/straight.el/archive/master.zip) and unzip it.  Not the biggest burden, I suppose.

    (defvar bootstrap-version)
    (let ((bootstrap-file
           (expand-file-name "straight/repos/straight.el/bootstrap.el" user-emacs-directory))
          (bootstrap-version 5))
      (unless (file-exists-p bootstrap-file)
        (with-current-buffer
    	(url-retrieve-synchronously
    	 "https://raw.githubusercontent.com/raxod502/straight.el/develop/install.el"
    	 'silent 'inhibit-cookies)
          (goto-char (point-max))
          (eval-print-last-sexp)))
      (load bootstrap-file nil 'nomessage))


### Use-package

    (setq straight-use-package-by-default t)
    (setq use-package-hook-name-suffix nil)
    (straight-use-package 'use-package)


### Extra use-package keywords

1.  :custom-update

        (straight-use-package
         '(use-package-custom-update
           :host github
           :repo "a13/use-package-custom-update"))
        
        (require 'use-package-custom-update)


## Customize variables


### Put customizations in a separate file

    (setq custom-file
          (expand-file-name "custom.el" user-emacs-directory))


### A macro for ease of customization

    (defmacro cuss (var val &optional docstring)
      "Basically `:custom' from `use-package', broken out."
      `(funcall (or (get ',var 'custom-set) #'set-default)
    	    ',var ,val))


## Keep a tidy `~/.emacs`

    (use-package no-littering
      :custom
      (backup-directory-alist
       `((".*" . ,(no-littering-expand-var-file-name "backup/"))))

      (elpher-certificate-directory
       (no-littering-expand-var-file-name "elpher-certificates/")))
    
    (dolist (dir '("backup"
    	       "autosaves"
    	       "undos"
    	       "elpher-certificates"))

### Convert all files to UNIX-style line endings

from [Emacs Wiki](https://www.emacswiki.org/emacs/EndOfLineTips).

I add it to the `find-file-hook` *and* `before-save-hook` because I don't want to ever work with anything other than UNIX line endings ever again.  I just don't care.  Even Microsoft Notepad can handle UNIX line endings, so I don't want to hear it.

## Org mode

I’ve put org mode under Applications, as opposed to Writing, because it’s  more generally-applicable than that.

    (use-package org
      :mode ("\\.org\\'" . org-mode)
    
      :bind (:map org-mode-map
    	      ("M-n" . outline-next-visible-heading)
    	      ("M-p" . outline-previous-visible-heading))
    
      :custom
      (org-hide-emphasis-markers t)
      (org-fontify-done-headline t)
      (org-fontify-whole-heading-line t)
      (org-fontify-quote-and-verse-blocks t)
      (org-pretty-entities t)
      (org-num-mode +1)
