Emacs Configuration
Summary
I've really been wanting to have a nicely formatted emacs config file and this is my attempt at it.
Required Magic
Lexical Binding
;;; -*- lexical-binding: t -*- ;;; DO NOT EDIT THIS FILE DIRECTLY ;;; EDIT ~init.org~ instead
The Magical Glue
The following auto compiles the emacs-lisp within the init.org file.
Simply run `org-babel-tangle` to make it RAIN!
;; (setq byte-compile-warnings nil)
(defun tangle-init ()
"If the current buffer is 'init.org' the code-blocks are tangled, and the tangled file is compiled."
(when (equal (buffer-file-name)
(expand-file-name (concat user-emacs-directory "init.org")))
;; Avoid running hooks when tangling.
(let ((prog-mode-hook nil))
(org-babel-tangle)
(byte-compile-file (concat user-emacs-directory "init.el")))))
