"ignoreheading" for non-beamer export

"ignoreheading" for non-beamer export

[James Harkins]

Hi, I found an inventive solution by Suvayu to discard headlines from export here [1], but the 8.0+ solution throws an error in my environment.

(defun sa-ignore-headline (contents backend info)
  "Ignore headlines with tag `ignoreheading'."
  (when (and (org-export-derived-backend-p backend 'latex 'html 'ascii)
          (string-match "\\`.*ignoreheading.*\n"
                (downcase headline)))
    (replace-match "" nil nil headline)))

(add-to-list 'org-export-filter-headline-functions 'sa-ignore-headline)

--> string-match: Symbol's value as variable is void: headline

It seems it should actually be:

(defun sa-ignore-headline (contents backend info)
  "Ignore headlines with tag `ignoreheading'."
  (when (and (org-export-derived-backend-p backend 'latex 'html 'ascii)
          (string-match "\\`.*ignoreheading.*\n"
                (downcase contents)))
    (replace-match "" nil nil contents)))

(add-to-list 'org-export-filter-headline-functions 'sa-ignore-headline)

I'm not allowed to reply to the answer on stackexchange, so I'm posting here.

Thanks.

Oops, typo!  Also a correction, I had a solution for the old exporter.
If I recall correctly Nick Dokos helped me come up with it.  The 8.0<
solution was from Rasmus based on suggestions from Nicolas.

I'll update the answer on SO.

Thanks for checking it,
