;;; app/regex/config.el

;; Often, I find myself writing regular expressions that could terrify seasoned
;; programmers (or little children). To hone my regex fu, I need a regex
;; playground. Sure, there's regexr.com, but don't be silly, that's not Emacs.
;;
;; Sadly, the Emacs' regex syntax is niche and lacks support for a few
;; questionably useful features, like lookaround assertions, conditionals, case
;; modifiers or backreferences, among others. No, I want PCRE. I am going to
;; have my cake and eat it too, damn it!
;;
;; Workflow:
;;   + Invoke `=regex' (if opened with C-u, opens in separate workspace with a
;;     dummy text buffer).
;;   + A regex window will popup up. Any matches will be highlighted in the
;;     original buffer.
;;   + C-c C-k to close it
;;   + TODO C-c C-e to export to various langauges
;;
;; WARNING: THIS IS A WORK IN PROGRESS
