#+STARTUP: showall
Some things have to be done to make sure that everything works as it
should. This includes enabling lexical binding, loading Cask and
keeping some comments.
* Use lexical binding
For some of my functions, and general coolness, lexical binding is a
must. Without it, closures cannot be made for example.
#+BEGIN_SRC emacs-lisp :padline no
;; -*- lexical-binding: t -*-
#+END_SRC
This line needs to appear at the beginning of the file to work. Just
to keep things looking nice I put it at the beginning of the file.
* Keep package.el from changing my init
Some time ago my init file was changed by Emacs. It added a single
line of code and some explanatory comments. Apparently I need to
keep this comment in my initialization file so that Emacs doesn't
try to add the code again. I actually use [[http://cask.readthedocs.org/en/latest/][Cask]] to manage and load my
packages so I don't need this.
#+BEGIN_SRC emacs-lisp
;; (package-initialize)
#+END_SRC
* Load Cask
I use Cask to manage my installed packages and for that to work I
need to load Cask at the start of the initialization file. This
should be executed both when byte-compiling and loading at run-time
so that other bits and pieces can byte-compile without warnings or
errors.
#+BEGIN_SRC emacs-lisp
(eval-and-compile
(require 'cask "~/projects/ext/cask/cask.el")
(cask-initialize))
#+END_SRC
