* bug#37034: 26.2.90; checkdoc doesn't support cl-defgeneric, cl-defmethod and cl-defun

Hi,

I rely on checkdoc to write clean docstrings. I rely on CL when writing
libraries to facilitate writing extensions through
specialization. Nevertheless, checkdoc won't check the docstrings of
cl-defgeneric, cl-defmethod and cl-defun.

Best,

Patch attached should fix the issue.

Hi Alex,

Alex Branham <alex.branham@gmail.com> writes:
> tags 37034 + patch

thank you for your patch. Nevertheless, it's not going to be enough. For
example, CL methods can have this signature:

(cl-defmethod navigel-children ((entities list) callback)
  "Execute CALLBACK with the children of ENTITIES as argument."
  (navigel-async-mapcar entities  #'navigel-children callback))

But this crashes checkdoc+patch because it expects each element of the
parameter list to be a symbol which (entities list) is not.

Also, CL methods accept &key and &context to specify parameters. Those
should be taken care of by checkdoc in one way or another.

True, thanks for reminding me. The attached patch should take care of
these two scenarios.

After doing some light testing, this seems to work for me too, and I'm
applying the patch.

I think there are problems with this patch. I opened a new bug report:
bug#37063.
