Display docstrings present in a buffer

Display docstrings present in a buffer

[Heime]

Is there a way to display docstrings in a buffer ?  On at least to the first blank line.

Did this but the buffer remains blank

(defun display-defun-lines ()
  "Display lines starting with `(defun` in a new buffer."
  (interactive)
  (let ((regexp "^\\s-*(defun.*")
        (output-buffer (get-buffer-create "*Defun Lines*")))
    (with-current-buffer output-buffer
      (erase-buffer)  ;; Clear previous contents
      (goto-char (point-min))
      (while (re-search-forward regexp nil t)
        (let ((line (match-string-no-properties 1)))
          (insert (concat line "\n"))))
      (display-buffer output-buffer))))

I want to try something else,  Make a function that matches a starting "(defun"
up to either tho clause (interactive) or two blank lines.

I know you've written further since this email, but just to offer 
you an alternative idea, if the function definitions in the buffer 
have already been evaluated, you can retrieve the docstring using 
the "documentation" function (info "(elisp) Accessing 
Documentation"). If this is something you can use, the problem 
reduces to retrieving the list of functions from the buffer, which 
you can perhaps do with imenu's index.
