* Blocks, Parentheses and Formatting Oh My!

** Parentheses, and Structural Editing

Sometimes if I delete a parenthesis out of hand I spend the next minute or two
kicking myself as I count the parentheses here and there.  Well no more!  With
[[https://shaunlebron.github.io/parinfer/][Parinfer]] structural editing, and taming parentheses becomes a
breeze.

#+begin_src emacs-lisp
(use-package parinfer-rust-mode
  :ensure t
  :init
  (setq parinfer-rust-auto-download t)
  :hook (emacs-lisp-mode . parinfer-rust-mode))
#+end_src

I also have =smart-parens= for parentheses matching in modes where =parinfer= would
be overkill.

#+begin_src  emacs-lisp
(use-package smartparens
  :ensure t
  :hook (prog-mode text-mode markdown-mode)
  :config
  (require 'smartparens-config))
#+end_src

Might as well highlight the parentheses to make them easier to spot.

#+begin_src emacs-lisp
(use-package highlight-parentheses
  :ensure t
  :hook
  (prog-mode . highlight-parentheses-mode))
#+end_src

** Apheleia

[[https://github.com/radian-software/apheleia][Aphelia]] tries to use the right formatting for any file and applies it asynchronously.

#+BEGIN_SRC emacs-lisp
(use-package apheleia
  :config
  (apheleia-global-mode +1))
#+END_SRC

** Indentation Level

#+begin_src emacs-lisp
;; Indent guides
(use-package highlight-indent-guides
  :defer t
  :hook (prog-mode . highlight-indent-guides-mode))
#+end_src

** List, and String Improvements

#+begin_src emacs-lisp
(use-package dash :ensure t)
(use-package s :ensure t)
#+end_src
