 ** Auto-fill-mode for text based buffers

+Instead of actually changing the text of the buffer by introducing end of lines when using =auto-fill-mode=,
+it is possible to use the option =visual-line-mode=, which can be further extended with the package
+=visual-fill-column=. [[https://github.com/joostkremers/visual-fill-column][This last package]] makes possible that instead of wrapping lines at the window edge,
+which is the standard behavior of =visual-line-mode=, it wraps lines at =fill-column=.
+
+#+begin_src emacs-lisp
+  (use-package visual-fill-column
+    :ensure t
+    :config
+    (add-hook 'visual-line-mode-hook #'visual-fill-column-mode)
+    ;; (setq-default visual-fill-column-center-text t)
+    )
+#+end_src
+
+Next line activates =visual-line-mode= globally, but this will affect all buffers and that's is most of the
+time unnecessary. One can always activate it manually.
+
+#+begin_src emacs-lisp
+  ;; (global-visual-line-mode 1)
+#+end_src
+
+Next we set the columns number where to cut

+#+begin_src emacs-lisp

+  (setq column-number-mode t)

+And finally use the =adaptive-wrap= package to avoid that the next line, when artificially broken by
+=visual-fill-column=, be more on the left than its parent, in case the parent was indented.

+#+begin_src emacs-lisp
