Every time, I press 'Enter' in org docs it prompts

Debugger entered--Lisp error: (wrong-type-argument wholenump -47)
  make-list(-47 nil)
  call-interactively(paredit-newline nil nil)

google search returns few answer to the debugger error.

What's the problem?

    Might it be that you have lisp or emacs-lisp code blocks in your org file? The lisp parser causes the problems in connection with paredit. If you switch paredit off the problem should be gone. – Tobias Jun 26 '19 at 7:41
  • inform us about emacs-version, org-version, and the version of paredit. Can you reproduce the problem with emacs -Q after M-x package-initialize <RET>? – Tobias Jun 26 '19 at 7:48

    This might be Bug#35286 or Bug#30891 – npostavs Jun 26 '19 at 12:27
  • org-version 9.1.9 emacs-version 26.1. cannot reproduce the problem with emacs -Q @Tobias – AbstProcDo Jun 27 '19 at 1:03

    @Tobias I don't really see the point in copying your answer; you've already credited me in the text, and my name is on the patches in the Emacs git repo. Digesting the bug report patch into an easy-to-use init file snippet is what you get credit for, which seems fine to me. – npostavs Jun 27 '19 at 11:35

Npostavs referenced Bug#35286 and Bug#30891 in his comment.

Note: I do not want to take credit for Noam Postavky's findings. The hard task is to find the bug. I just "copied" his patch here. So, please try the proposed bugfix.

You told us that your emacs-version is 26.1. That leaves us only with Bug#30891.

There are two indicators that your problem is Bug#30891:

  • The problem deals with negative depths.
  • The problem is found in Emacs 26.1 and fixed in Emacs 26.2.

This problem should be fixed with the following code in your init file:

(defun lisp-indent-calc-next-patch (state)
  "Move to next line and return calculated indent for it.
STATE is updated by side effect, the first state should be
created by `lisp-indent-initial-state'.  This function may move
by more than one line to cross a string literal."
  (pcase-let* (((cl-struct lisp-indent-state
                           (stack indent-stack) ppss ppss-point)
               (indent-depth (car ppss)) ; Corresponding to indent-stack.
               (depth indent-depth))
    ;; Parse this line so we can learn the state to indent the
    ;; next line.
    (while (let ((last-sexp (nth 2 ppss)))
             (setq ppss (parse-partial-sexp
                         ppss-point (progn (end-of-line) (point))
                         nil nil ppss))
             ;; Preserve last sexp of state (position 2) for
             ;; `calculate-lisp-indent', if we're at the same depth.
             (if (and (not (nth 2 ppss)) (= depth (car ppss)))
                 (setf (nth 2 ppss) last-sexp)
               (setq last-sexp (nth 2 ppss)))
             (setq depth (car ppss))
             ;; Skip over newlines within strings.
             (nth 3 ppss))
      (let ((string-start (nth 8 ppss)))
        (setq ppss (parse-partial-sexp (point) (point-max)
                                       nil nil ppss 'syntax-table))
        (setf (nth 2 ppss) string-start) ; Finished a complete string.
        (setq depth (car ppss)))
      (setq ppss-point (point)))
    (setq ppss-point (point))
    (let* ((depth-delta (- depth indent-depth)))
      (cond ((< depth-delta 0)
             (setq indent-stack (nthcdr (- depth-delta) indent-stack)))
            ((> depth-delta 0)
             (setq indent-stack (nconc (make-list depth-delta nil)
        (let (indent)
          (cond ((= (forward-line 1) 1) nil)
                ;; Negative depth, probably some kind of syntax error.
                ((null indent-stack)
                 ;; Reset state.
                 (setq ppss (parse-partial-sexp (point) (point))))
                ((car indent-stack))
                ((integerp (setq indent (calculate-lisp-indent ppss)))
                 (setf (car indent-stack) indent))
                ((consp indent)       ; (COLUMN CONTAINING-SEXP-START)
                 (car indent))
                ;; This only happens if we're in a string.
                (t (error "This shouldn't happen"))))
      (setf (lisp-indent-state-stack state) indent-stack)
      (setf (lisp-indent-state-ppss-point state) ppss-point)
      (setf (lisp-indent-state-ppss state) ppss))))

(with-eval-after-load 'lisp-mode
  (if (version<= "26.2" emacs-version)
      (warn "If you exclusively use Emacs >= 26.2 you can remove `lisp-indent-calc-next-patch'")
    (advice-add 'lisp-indent-calc-next :override #'lisp-indent-calc-next-patch)))
