Struggling with new exporter

[phillip.lord@newcastle.ac.uk (Phillip Lord)]

I'm rather struggling with the new exporter. I fear I have used a
combination of old and new configuration which cannot be helping.
I am trying to get publishing working mostly in batch, so that it will
work as part of my continuous integration framework. But having it work
interactively would be nice also.

I have installed the org-mode daily from the Org ELPA. I have a file
called book.org, which also includes several other files.

I want to publish to HTML and PDF. It would be nice to publish to
some kind of chunked HTML also, as the file will get quite long, but for
the moment I can live with out this.


The headers look like this:

#+LATEX_HEADER: \usepackage{tawny}
#+LATEX_HEADER: \lstnewenvironment{tawny}{\lstset{style=tawnystyle}}{}

#+BIND: org-publishing-directory "./exports"
#+BIND: org-latex-custom-lang-environments ((clojure "tawny"))
#+BIND: org-latex-listings t

Tawny is my own package, and is present in the same location as the org
file. It provides the syntax highlighting support latex. 

Now, by original batch build commands looked like this...

(defun build/pdf ()
  (with-current-buffer
      (find-file-noselect build-source-file)
    (org-export-as-pdf
     org-export-headline-levels)))

(defun build/html ()
  (init-faces)
  (setq htmlize-use-rgb-map 'force)
  (with-current-buffer
      (find-file-noselect build-source-file))
    (org-export-as-html-batch org-export-headline-levels))

but these are using the old org-export functions.

My current version looks like this...

(defun build/html ()
  (init-faces)
  (setq htmlize-use-rgb-map 'force)
  (with-current-buffer
      (find-file-noselect build-source-file))
  (org-html-publish-to-html
   ;; publishing plist
   nil
   ;; output file name
   "book.html"
   ;; directory
   "exports"))

Which is crashing with:

Debugger entered--Lisp error: (error "`org-publish-cache-get' called, but no cache present")
  signal(error ("`org-publish-cache-get' called, but no cache present"))
  error("`org-publish-cache-get' called, but no cache present")

Interactively, the publishing works BUT the bind forms appear to do
nothing. My source code is coming up verbatim and the publishing
directory is being ignored.

Any help gratefully recieved!
