Create a small Elisp file such as (a.el):

;;; a.el --- aaa -*- lexical-binding: t; -*-

;;; Commentary:

;;; Code:

(defun a--bar () 123)

;;; a.el ends here

Run M-x checkdoc.  It will complain about the missing docstring for
`a--bar'.

Now remove the space before () and run checkdoc again.  It won't
complain any more.

Hello,

I found that the commit 'b5b997b95' breaks a valid defvar, see
attached example file 'b.el'. If I run 'M-x checkdoc' in Emacs after
that commit (I tried in Emacs compiled from commit 112460da70) it shows
me error message (copy-pasted from *Message* buffer):

  forward-sexp: Scan error: "Containing expression ends prematurely", 60, 61

while before that commit (I tested in Emacs compiled from commit
e5ef59b87d) it works like a charm.

[...]

on second thought, the original 'checkdoc-defun-regexp' seems to be
wrong. According to it's docstring, it's purpose to stop before
parameter list, but 'defvar' may not have that list.

Thanks for reporting. I've attached a patch that replaces the regex
completely.

Subject: [PATCH] Checkdoc: use syntax functions instead of regex

In checkdoc.el, get rid of the error-prone regex to find definition
forms, and use existing syntax-based navigation functions instead.
This fixes a corner case with one-argument `defvar' forms.

* lisp/emacs-lisp/checkdoc.el (checkdoc--next-docstring): New function.
(checkdoc-next-docstring, checkdoc-defun): Use it.
* test/lisp/emacs-lisp/checkdoc-tests.el (checkdoc-tests--next-docstring):
Add unit test.
