export subtree from the command line

export subtree from the command line

Hello,

I'm teaching a class where I have a big monolithic file for all the
lectures. Right now I export each lecture as a subtree from the file
itself, but I would like to do it from a Makefile. Is it possible to
export a subtree from the command line? if so, how do I specify the
subtree that I want?

Thanks,

Alan

Use an ID property for the subtree.

A small *.el file can set prereqs, find the subtree from the ID, and
call up the exporter.

`make test' does something like this. If you look at 
testing/lisp/test-ob.el, testing/examples/babel.org, and the testing/*.el 
files you can see some of this in action.

HTH,

Chuck

Thanks a lot for the suggestion, I'll give it a try.

For a different approach, you could make this kind of an emacs script. I
have not done this too often, and it can be tricky to setup and debug.

#+BEGIN_SRC emacs-lisp :tangle export-org-section :shebang #!/bin/sh
:;exec emacs -batch  -l ~/Dropbox/kitchingroup/jmax/init.el -l "$0" "$@"

;; usage: export-org-section section-id org-file

;; now goto, narrow and export the section
(let ((section-id (pop command-line-args-left))
      (org-file (pop command-line-args-left)))
  (print (format "Opened %s" org-file))
  (find-file (expand-file-name org-file))
  (org-open-link-from-string (format "[[#%s]]" section-id))
  (org-narrow-to-subtree)
  (org-latex-export-to-pdf)
)
#+END_SRC


#+BEGIN_SRC sh :results silent
rm -f blog.pdf
./export-org-section sec-2 blog.org
open blog.pdf
#+END_SRC

Very interesting! Thank you for the suggestion.
