Swap clever parens for lispyville

Browse source 
The lispy+lispyville is more feature-rich than the
smart-parens+clever. Both are fantastic, but I'm switching my lisp
work for lispyville.

** Lispyville
I want an Evil version of [[Lispy]]. The [[https://github.com/noctuid/lispyville][lispyville project]] builds on it to make it Evil. From the README:
#+begin_quote
The main difference from an evil state is that lispy’s “special” is contextually based on the point (special is when the point is before an opening delimiter, after a closing delimiter, or when there is an active region).
#+end_quote
The [[https://github.com/luxbock/evil-cleverparens][evil-cleverparens]] solves having me create keybindings to the [[https://github.com/Fuco1/smartparens][smartparens]] project by updating the evil states with Lisp-specific bindings. Many of the operations supplied by =lispyville= don’t require learning anything new. Similar to [[Clever Parenthesis]], we can
For instance, if our point is placed at this location in this code:
#+begin_src emacs-lisp #+begin_src emacs-lisp
(use-package evil-cleverparens (message "The answer is %d" (+ 2 (* 8 5)‸ 9 (+ 1 4)))
:after smartparens
:custom
(evil-cleverparens-use-additional-bindings t)
(evil-cleverparens-use-additional-movement-keys t)
(evil-cleverparens-use-s-and-S t)
:init
(require 'evil-cleverparens-text-objects)
:hook
(prog-mode . evil-cleverparens-mode)) ;; All the languages!
;; Otherwise: (emacs-lisp-mode . evil-cleverparens-mode)
#+end_src #+end_src
Pressing ~D~ results in:
#+begin_src emacs-lisp
(message "The answer is %d" (+ 2 (* 8 5)‸))
#+end_src
And doesn’t delete the trailing parenthesis.
The /trick/ to being effective with the [[https://www.emacswiki.org/emacs/ParEdit][paredit-family]] of extensions is learning the keys. The killer “app” is the slurp/barf sequence. Use the ~<~ key, in normal mode, to barf (or jettison)… in other words, /move/ the paren closer to the point.

#+end_src #+end_src
*Opening Parens.* Those two keys seem straight-forward, but they behave differently when the are on the opening parens. *Note:* I used to use the [[https://github.com/luxbock/evil-cleverparens][evil-cleverparens]] project to have similar keybindings but in all programming languages. I found that =lispyville= is a little more reliable, and that I don’t really use these types of code manipulation in my day-job programming languages of Python and YAML.
When the point (symbolized by ~‖~) is /on/ the opening paren, ~<~ moves the paren to the left. For instance:
#+begin_src emacs-lisp :tangle no
(+ 41 ‖(* 1 3)) ⟹ (+ ‖(41 * 1 3))
#+end_src
And the ~>~ moves the paren to the right. For instance:
#+begin_src emacs-lisp :tangle no
(+ 41 ‖(* 1 3)) ⟹ (+ 41 * ‖(1 3))
#+end_src
I would like to have a list of what keybindings that work in =normal= mode: #+begin_src emacs-lisp
- ~M-h~ / ~M-l~ move back/forward by functions (use-package lispyville
- ~H~ / ~L~ move back/forward by s-expression :after lispy
- ~M-i~ insert at the beginning of the form :hook ((emacs-lisp-mode-hook lisp-mode-hook) . lispyville-mode)
- ~M-a~ appends at the end of the form
- ~M-o~ new form after the current sexp
- ~M-O~ new form /before/ the current sexp
- ~M-j~ / ~M-k~ drags /thing at point/ and back and forth in the form
- ~>~ slurp forward if at the end of form, at beginning, it barfs backwards
- ~<~ slurp backward if at start of form, at the end, it barfs forwards
- ~M-(~ / ~M-)~ wraps next/previous form in parens (braces and brackets work too)
- ~x~ unwraps if the point is on the =(= of an expression.
- ~D~ deletes an entire s-expression, but this can depend on the position of the point.
The other advantage is moving around by s-expressions. This takes a little getting used to, for instance:
- ~[~ and ~]~ move from paren to paren, essentially, from s-expression.
- ~H~ and ~L~ act similarly to the above.
- ~(~ and ~)~ move up to the parent s-expression
We need a real-world example. Let’s suppose we entered this:
** Clever Keybindings
Adding a bunch of meta-key keybindings to the Normal state seems like I’m going backwards away from the /key sequences/ of Evil. First, adding frequently used (especially key movements) on the ~g~ key seems nice. Since I never bother with [[help:find-file-at-point][find-file-at-point]], I figured I could re-purpose that keybinding:
#+begin_src emacs-lisp :tangle no
(format "The sum of %d %d is %d" a b (+ a b))
(use-package evil-cleverparens
:general
(:states 'normal :keymaps 'prog-mode-map
"gf" '("evil cleverparens" . evil-cleverparens-hydra/body)
"H" 'evil-cp-backward-sexp
"L" 'ha-cp-forward-sexp))
#+end_src
But we forgot to define the =a= and =b= variables. One approach, after Escaping into the normal state, is to hit ~(~ to just to the beginning of the s-expression, and then type, ~M-(~ to wrap the expression, and type ~i~ to go into insert mode:
For all the rest, why not make a Hydra using the pretty-hydra project:
#+begin_src emacs-lisp :tangle no
(‖ (format "The sum of %d %d is %d" a b (+ a b)))
#+end_src
And now we can enter the =let= expression.

Instead of converting /all keybindings/, the project supplies /key themes/ to grab specific keybinding groups.
- =operators= :: basic VI operators that keep stuff balanced
- =c-w= :: replaces the ~C-w~, but since that is VI-specific, I rebind this to ~M-Delete~
- =text-objects= :: Add more text-objects, I wrote my [[file:ha-config.org::*Better Parenthesis with Text Object][own version]] for s-expressions, but I might try these
- =atom-movement= :: The ~e~ / ~w~ and ~b~ keys will move by /symbols/ instead of /words/.
- =additional-movement= :: Adds new movement keys, ~H~ / ~L~ for s-expr and the ~(~ / ~)~ for getting to closest expressions. This doesn’t work well, but is easy to re-implement.
- =commentary= :: Replace ~gc~ for un/commenting Lisp elements.
- =slurp/bar-lispy= :: always allow ~<~ / ~>~ to slurp/barf even /inside/ an s-expression.
- =additional= :: New ~M-~ bindings for manipulating s-expressions. ~M-J~ is very cool.
- =additional-insert= :: ~M-i~ insert at beginning, and ~M-a~ to insert at the end of a list.
- =wrap= :: like [[file:ha-config.org::*Evil Surround][Evil Surround]] but with one less keystroke. ~M-( M-(~ wraps the entire line.
- =additional-wrap= :: is another version of the =wrap= that automatically wraps current symbol, and then you can slurp in the rest.
- =mark= :: The ~v~ will highlight current symbol, and ~V~ will highlight current s-expression. Continues to work with [[file:ha-config.org::*Expand Region][Expand Region]].
New bindings to remember:
- ~>~ :: slurp
- ~<~ :: barf
- ~H~ :: backward s-expression
- ~L~ :: forward s-expression
- ~M-h~ :: beginning of defun
- ~M-l~ :: end of defun
- ~M-i~ :: insert at beginning of list
- ~M-a~ :: insert at end of list
- ~M-o~ :: open below list … never worry about inserting into a bunch of closing parens.
- ~M-O~ :: open above list
- ~M-j~ :: drag forward
- ~M-k~ :: drag backward
- ~M-J~ :: join
- ~M-s~ :: splice … I could use specific examples for these operations so I would know when to use them.
- ~M-S~ :: split
- ~M-r~ :: raise s-expression
- ~M-R~ :: raise list
- ~M-t~ :: transpose s-expressions
- ~M-v~ :: convolute s-expression
These are all good, but the primary keys I need to figure out, are the s-expression movement keys:
- ~{~ :: backward up list … nice to hit once (maybe twice), but isn’t something to use to navigate
- ~}~ :: next opening parenthesis
- ~(~ :: previous opening paren
- ~)~ :: next closing parenthesis

*** Move by Functions
The =mark-paragraph= and =downcase-word= isn’t very useful in a programming context, and makes more sense to use them to jump around function-by-function:
#+begin_src emacs-lisp
(evil-define-key '(normal insert emacs) prog-mode-map
(kbd "M-h") 'beginning-of-defun
(kbd "M-l") 'beginning-of-next-defun)
#+end_src
But one of those functions doesn’t exist:
#+begin_src emacs-lisp
(defun beginning-of-next-defun (count)
"Move to the beginning of the following function."
(interactive "P")
(end-of-defun count)
(end-of-defun)
(beginning-of-defun))
#+end_src
Once upon a time, we use to create a =TAGS= file that contained the database for navigating code bases, but with new faster versions of grep, e.g. [[https://beyondgrep.com][ack]], [[https://github.com/ggreer/the_silver_searcher][ag]] (aka, the Silver Searcher), [[https://github.com/Genivia/ugrep][ugrep]] and [[https://github.com/BurntSushi/ripgrep][ripgrep]], we should be able to use them. but I want to: Once upon a time, we use to create a =TAGS= file that contained the database for navigating code bases, but with new faster versions of grep, e.g. [[https://beyondgrep.com][ack]], [[https://github.com/ggreer/the_silver_searcher][ag]] (aka, the Silver Searcher), [[https://github.com/Genivia/ugrep][ugrep]] and [[https://github.com/BurntSushi/ripgrep][ripgrep]], we should be able to use them. but I want to:
