I'm trying to derive an exporter backend from ASCII. I need to add some export
options, so I have:
#+BEGIN_SRC {emacs-lisp}
(org-export-define-derived-backend 'scdoc 'ascii
:translate-alist ... omitted for brevity...
:options-alist
'((:categories "CATEGORIES" nil nil t)
(:related "RELATED" nil nil t)
(:summary "SUMMARY" nil nil t)
(:redirect "REDIRECT" nil nil t))
)
... snip snip...
(defun org-scdoc-template (contents info)
"Return complete document string after SCDoc conversion.
CONTENTS is the transcoded contents string. INFO is a plist
holding export options."
(let* ((title (org-export-data (plist-get info :title) info))
(categories (org-export-data (plist-get info :categories) info))
(related (org-export-data (plist-get info :related) info))
(summary (org-export-data (plist-get info :summary) info))
(redirect (org-export-data (plist-get info :redirect) info))
(output (format "TITLE:: %s\n" title)))
(if categories (setq output (concat output (format "CATEGORIES:: %s\n"
categories))))
(if related (setq output (concat output (format "RELATED:: %s\n"
categories))))
(if summary (setq output (concat output (format "SUMMARY:: %s\n"
categories))))
(if redirect (setq output (concat output (format "REDIRECT:: %s\n"
categories))))
(concat output "\n\n" contents)))
#+END_SRC
(Pardon the un-idiomatic Emacs-lisp.)
Then I created an org file that begins:
#+BEGIN_SRC org
,#+title:: PulseCount
,#+summary:: Pulse counter.
,#+related:: Classes/Stepper
,#+categories:: UGens>Triggers
,* Description
Each trigger increments a counter which is output as a signal.
#+END_SRC
Then I run org-scdoc-export-as-scdoc, and I get as the first few lines:
TITLE::
CATEGORIES::
RELATED::
SUMMARY::
REDIRECT::
... telling me that the template function retrieved empty strings for all the
export options.
Obviously I've done something wrong, but... what? "(let ((title
(org-export-data (plist-get info :title) info)))...)" is copied from
ox-latex.el, and ox-latex clearly has no problem accessing the title.
Thanks in advance. I'm sure I'll have other questions later.
