Famous init files

• The Big Zemansky
• Patrick: GOAT init emacs
• Manugoyal: Emacs config
• System Crafters
• System Crafters emacs-from-scratch
• System Crafters configs compilation

Before this file loads

early-init.el has been loaded.

This file inhibits package.el for loading packages

init.el has been loaded

This file:

• Set all that it's needed for straight.el working as package manager
• IMPORTANT Changes the user-emacs-directory from ~/.emacs.d to ~/.cache/emacs. This can be really important in case you change something fundamental in emacs configuration
• Load the no-littering package (see doc) This package sets out to fix this by changing the values of path variables to put configuration files in no-littering-etc-directory (this will be ~/.cache/emacs/etc/ for this configuration) and persistent data files in no-littering-var-directory (for me: ~/.cache/emacs/var/), and by using descriptive file names and subdirectories when appropriate. This is similar to a color-theme; a "path-theme" if you will.
• Tries to install org-mode just to be sure to have the last release
• Loads the newer of this two files: myconfig.org and myconfig.el. In other words, if there are no new changes in myconfig.org it loads myconfig.el (it's faster)

use-package tips

Some notes about use-package

• :ensure if true will install the package if not installed It won't update packages. See auto-package-update for keeping all packages up to date
• :init keyword to execute code before a package is loaded. It accepts one or more foorms, up to the next keyword
• :config can be used to execute code after a package is loaded. In cases where loading is done lazily (see more about autoloading below), this execution is deferred until after the autoload occurs
• :custom permite configurar variables con syntaxis simplificada
• :bind
• bind-keymap
• :mode and :interpreter
• :magic
• :hook
• :if
• :defer En general use-package intenta aplicar lazy loading, pero en algún paquete es necesario especificarlo explicitamente
• :demand Este es el contrario del anterior, para paquetes que queremos cargar de inmediato
• :diminish and :delight changes minormode display in status line
