;;; Commentary:
;; These functions are intended to be bound to KBDs for daily use and
;; refactoring.
;;; Code:
(require 's)
(require 'dash)
;; todo - grab the string at point and replace it with the output of
;; each fn

"Change the casing of X from CAP_CASE to kebab-case."
(->> x
s-downcase
(s-replace "_" "-")))
(defun kebab->caps (x)
"Change the casing of X from CAP_CASE to kebab-case."
(->> x
s-upcase
