Convolute

[bpstahlman]

Synopsis Adds a convolute command, similar to the one provided by Emacs Paredit, but significantly smarter: e.g., breaks only at sensible locations, and preserves bracket types.

Intended Use Case Widen the scope of a let binding to include [count] ancestor forms. The following examples illustrate the intended usage. Note: cursor position denoted by `|'

Original Form:

(defun foo (a b)
  (if (bar x y)
      (baz (let ((x 1) (y 2))
             |(+ x y)))))

Example 1: convolute with [count]=1 (default):

(defun foo (a b)
  (if (bar x y)
      (let ((x 1) (y 2))
        (baz |(+ x y)))))

Example 2: convolute with [count]=2:

(defun foo (a b)
  (let ((x 1) (y 2))
    (if (bar x y)
        (baz |(+ x y)))))

I am unfamiliar with the convolute command in Emacs Paredit, so I will have to take your word on the implementation. Thank you.

No problem. I tested a number of examples in both vim-sexp and Paredit, and the results were pretty much identical, except in cases where I thought Paredit should have been a little smarter.
