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 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

lsp-treemacs

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

  (use-package lsp-treemacs
    :after lsp)

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 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!

  ;;   ;; Uncomment the config below if you want all UI panes to be hidden by default!
  ;;   ;; :custom

  ;;   :config
  ;;   ;; Set up Node debugging
  ;;   (require 'dap-node)
  ;;   (dap-node-setup) ;; Automatically installs Node debug adapter if needed

Python

We do need a Python language server installed in the developing enviroment (pip install python-lsp-server[all])

Use latest python

Not needed if you have the right settings on your active python with pyenv

; (setq python-shell-interpreter "/usr/bin/python3.8")
; (setq py-python-command "/usr/bin/python3.8")        ; maybe not needed
; (setq python-python-command "/usr/bin/python3.8")    ; maybe not needed

Configure python mode

  (use-package python-mode
    :hook (python-mode . lsp-deferred)
    ;; :custom
    ;; (dap-python-debugger 'debugpy)
    ;; 
    ;;;;; NOTE: Set these if Python 3 is called "python3" on your system!
