Someone recently posted a tip to add
:post (org-redisplay-inline-images)
to a SRC block which generates an image in order to freshen the Emacs
buffer with the regenerated image each time the block is executed. It
works *almost* fine but I have two problems which I hope someone can
help with.
1) Priming-the-pump
I'm using a document containing a GraphViz graph and running "dot" on it:
----------------------------------------------------------------------
#+BEGIN_SRC dot :cmd dot :cmdline -Tpng :file foo.png :exports results :post (org-redisplay-inline-images)
digraph "foo" {
rankdir=LR;
params -> builders;
builders -> objects;
objects -> file;
}
#+END_SRC
----------------------------------------------------------------------
I do "C-c C-c" in the block and the buffer does not display any result.
I see the messages:
----------------------------------------------------------------------
No images to display inline
executing Dot code block...
Wrote /tmp/babel-11819Iqr/ob-input-11819Lrv
org-babel-ref-resolve: Reference 'No images to display inline' not found in this buffer
----------------------------------------------------------------------
If I do "C-c hh" to export to HTML I see:
----------------------------------------------------------------------
org-babel-exp processing...
No images to display inline [2 times]
executing Dot code block...
Wrote /tmp/babel-11819Iqr/ob-input-11819kTR
org-babel-ref-resolve: Reference 'No images to display inline' not found in this buffer
----------------------------------------------------------------------
And I get no HTML file produced.
If I now take out the :post and do "C-c C-c" I get this appearing just
after the SRC block as expected:
----------------------------------------------------------------------
#+RESULTS:
[[file:foo.png]]
----------------------------------------------------------------------
If I now add back the ":post" and do "C-c C-c" again I get the inlined
image. I can now edit the SRC block and repeat the "C-c C-c" and I am
pleased to see the figure refresh each time. It's great! But, it needs
this "pump priming".
2) Post-priming, still no HTML export
After this "priming the pump" is done the second problem is that still a
"C-c hh" does not produce an exported HTML file. Similar messages:
----------------------------------------------------------------------
org-babel-exp processing...
No images to display inline
Inline image display turned off
No images to display inline
executing Dot code block...
Wrote /tmp/babel-11819Iqr/ob-input-11819zYx
org-babel-ref-resolve: Reference 'No images to display inline' not found in this buffer
----------------------------------------------------------------------
Finally, if I remove the :post but leave the "#+RESULTS:" I can do
a successful "C-c hh".
So, the upshot is I have to keep adding and removing the :post to make
things work in different contexts. This is obviously not so smooth.
Is there some way to both have my cake an eat it too?
Thanks!
-Brett.

The :post trick works by side-effect: org-redisplay-inline-images does
what it says and it returns the string that `message' prints in the echo
area. Unfortunately, on export, :post is processed further with the
result that the meaningless string is passed to org-babel-ref-resolve
as a reference to be resolved - with predictable results[fn:1].
I think you'd be better off with the tip that Rick Frankel posted in
the same thread:
--8<---------------cut here---------------start------------->8---
#+BEGIN_SRC emacs-lisp
(add-hook 'org-babel-after-execute-hook
(lambda () (org-display-inline-images nil t)))
#+END_SRC
--8<---------------cut here---------------end--------------->8---
That's executed after you evaluate the block so it displays any
image(s) produced. And it does not interfere with export.
Footnotes:
[fn:1] Assuming 20-20 hindsight of course...

Thanks Nick (and Rick). I changed this to use the "re" version:
#+BEGIN_SRC emacs-lisp
(add-hook 'org-babel-after-execute-hook
(lambda () (org-redisplay-inline-images)))
#+END_SRC
and it works great!

It should work with the non-"re" version as well (and it is more
efficient that way - particularly if you call it with refresh == t).

As experienced by wdkmls [1], I noticed that the non-"re" version
stopped working -- preferred as it was the most efficient one.
OTOH, the "re" version does work as expected.
