I was extremely encouraged to see this, and it got my hopes up for export =) If remote file references could be resolved during export, that would be ideal. > A block like the following may be an acceptable workaround in the near > term (notice I named your block above). > > #+begin_src sh :file test.png :var remote=rplot :exports results > scp $remote ./test.png > #+end_src Nice suggestions, I'll try it later today.

Eric, here's an example where the exporter does not respect caching. - Tom
#+BABEL: :session *R* :results output :exports both :cache yes
* A test of caching
#+begin_src R
cat("random result:", runif(1), "\n")
Sys.sleep(2)
alarm()
#+end_src
#+results[b2549fac8a1ec2923ae289d47ce55fb2853dd1de]:
: random result: 0.2799064
#+begin_src R
cat("random result:", runif(1), "\n")
Sys.sleep(2)
alarm()
#+end_src
#+results[b2549fac8a1ec2923ae289d47ce55fb2853dd1de]:
: random result: 0.1625634
** cache on export
do we export cached blocks
#+begin_src emacs-lisp :cache yes :exports results
(random)
#+end_src
#+results[46632b4fe2e3a23e847953c95adcba58c270b381]:

Re: [Orgmode] Re: [babel] exports, caching, remote execution
Hi Tom,
Thanks for pointing this out. It appears that during export the code
block is evaluated in an altered version of the original buffer in which
(for some reason) Babel is sometimes not able to find properties which
are tucked away in either a #+Babel: line at the top of the file, or as
properties of an enclosing headline level.
This certainly merits a closer investigation, and has been recorded as a
bug. Most likely it will require picking apart the subtleties of the
actions taken by the exporter.
Thanks -- Eric

Re: [Orgmode] Re: [babel] exports, caching, remote execution
Hi Tom,
This turned out to be a fairly complicated issue.
During export of a narrowed region the narrowed region will be coppied
to a temporary buffer, when exporting from the buffer all buffer-wide,
and headline-wide parameters which are not included in the region are
ignored. This results in a different set of header arguments being used
for interactive evaluation than were used for export evaluation. These
differences in header arguments then invalidate the cache saved during
the interactive evaluation.
I've just put together and pushed a fix which involves jumping back to
the original org file to collect header arguments in context during
export. This appears to resolve the issue (at least for me). Please
let me know if it works for you.
Best -- Eric
