#+startup: overview
* Famous init files
- [[https://github.com/zamansky/dot-emacs][The Big Zemansky]]
- [[https://github.com/patrickt/emacs][Patrick: GOAT init emacs]]
- [[https://github.com/manugoyal/.emacs.d][Manugoyal: Emacs config]]
- [[https://github.com/daviwil/dotfiles/blob/master/Emacs.org][System Crafters]]

* 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 [[https://github.com/emacscollective/no-littering][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 [[https://github.com/jwiegley/use-package][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 forms, 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*
- *:commands*
- *:mode* and *:interpreter*
- *:magic*
- *:hook* You can define hooks
- *: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

Try these commands with M-x:
- =lsp-treemacs-symbols= - Show a tree view of the symbols in the
current file
- =lsp-treemacs-references= - Show a tree view for the references of
the symbol under the cursor
- =lsp-treemacs-error-list= - Show a tree view for the diagnostic
messages in the project

** DAP mode
[[https://emacs-lsp.github.io/dap-mode/][DAP-mode]] is an excellent package for bringing rich debugging
capabilities to Emacs via the Debug Adapter Protocol. You should check
out the [[https://emacs-lsp.github.io/dap-mode/page/configuration/][configuration docs]] to learn how to configure the debugger for
your language. Also make sure to check out the documentation for the
debug adapter to see what configuration parameters are available to
use for your debug templates!
