Wow! That looks pretty amazing. Makes we wish I used both a lisp and emacs... Does anyone know if there is anything similar that works for non-lispy languages (using syntax like do/end, {}, etc?) and in VSCode?
It's on the first line there "ParEdit (paredit.el) is a minor mode for performing structured editing of S-expression data. The typical example of this would be Lisp or Scheme source code." You'd have to known emacs nomenclature ( minor-mode ) and Lispy words ( S-expression )
I assume E: is for edit. I think GP was pointing out that the ParEdit website doesn't offer much in the way of explanation, and later found another site that did.
If you click paredit.el, there’s prose explanation in the comments.
