* Tangling src blocks to files as part of export

Is it possible to have certain blocks tangled as part of export so that they are available as input files to later source blocks?

E.g.,

#+BEGIN_SRC python :tangle hello.py
print "Hello World"
#+END_SRC

#+BEGIN_SRC sh
python hello.py
#+END_SRC

If I tangle before running, then the second code block will work; else, it fails because 'hello.py' is not found. [1]

I can run tangle and export in a row (and I have my own function to do just that) but is there a native org way to do so?

Michael

[1] My actual case involves a JAGS model file and the R code to run it, so executing the first source block directly isn't an option.

Adding org-babel-tangle to the org-export-before-processing-hook does the job, but I'd still be interested in knowing if there's a more official method.

For such a work, I'm using this home-made function:

--8<---------------cut here---------------start------------->8---
  (with-eval-after-load "org"

    (defun org-save-buffer-and-do-related ()
      "Save buffer, execute/tangle code blocks, and export to HTML/PDF."
      (interactive)
      (let* ((orgfile (buffer-file-name))
             (base-name (file-name-base orgfile))
             (htmlfile (concat base-name ".html"))
             (pdffile (concat base-name ".pdf")))
        (save-buffer)                     ; See other commands in
                                          ; `before-save-hook':
                                          ; `org-update-all-dblocks'
                                          ; `org-table-iterate-buffer-tables'.
        (when (derived-mode-p 'org-mode)
          ;; (org-babel-execute-buffer)   ; XXX Why should we execute all code blocks?
          (let ((before-save-hook nil))
            (save-buffer))
          (org-babel-tangle)
          (when (file-exists-p htmlfile)
            (if (file-newer-than-file-p orgfile htmlfile)
                (org-html-export-to-html)
              (message "HTML is up to date with Org file")))
          (when (file-exists-p pdffile)
            (if (file-newer-than-file-p orgfile pdffile)
                (if (string-match "^#\\+BEAMER_THEME: " (buffer-string))
                    (org-beamer-export-to-pdf)
                  (org-latex-export-to-pdf))
              (message "PDF is up to date with Org file")))
          (beep))))

    (define-key org-mode-map (kbd "<f9>") 'org-save-buffer-and-do-related))
--8<---------------cut here---------------end--------------->8---

I think this is the more-or-less official way of doing it - that's what
hooks are for: to do pre- and post-processing, which is exactly what you
want to do.

I like it actually.

Do you set the hook as a file local variable, and if yes, how?

Because this would be brilliant.

Cheers,

Rainer
