### Compile-Angel - Speed up Emacs by Automatically Byte-compiling and Native-compiling all .el files
The [compile-angel.el](https://github.com/jamescherti/compile-angel.el) package automatically byte-compiles and native-compiles Emacs Lisp libraries. It offers:
- `(compile-angel-on-load-mode)`: A global mode that compiles .el files before they are loaded.
- `(compile-angel-on-save-local-mode)`: A local mode that compiles .el files whenever the user saves them.
The *compile-angel* modes **speed up Emacs by ensuring all libraries are byte-compiled and native-compiled**. Byte-compilation reduces the overhead of loading Emacs Lisp code at runtime, while native compilation optimizes performance by generating machine code specific to your system.
To install compile-angel, add the following code **at the very beginning of your ~/.emacs.d/post-init.el init.el file, before all other packages**:
```emacs-lisp
(use-package compile-angel
:ensure t
:demand t
:config
(compile-angel-on-load-mode)
(add-hook 'emacs-lisp-mode-hook #'compile-angel-on-save-local-mode))
```
It is also highly recommended to set the following variables **at the very beginning of your post-init.el**:
``` emacs-lisp
;; Ensure Emacs loads the most recent byte-compiled files.
(setq load-prefer-newer t)
;; Ensure JIT compilation is enabled for improved performance by
;; native-compiling loaded .elc files asynchronously
(setq native-comp-jit-compilation t)
(setq native-comp-deferred-compilation t) ; Deprecated in Emacs > 29.1
```
### Reducing clutter in `~/.emacs.d` by redirecting files to `~/emacs.d/var/`
Emacs, by default, stores various configuration files, caches, backups, and other data in the `~/.emacs.d` directory. Over time, this directory can become cluttered with numerous files, making it difficult to manage and maintain.
