* Avoiding recompilation of ditaa ASCII if unmodified between exports

Hi,

I really appreciate the integration with ditaa and org mode.
http://orgmode.org/worg/org-contrib/babel/languages/ob-doc-ditaa.html

I have an Org mode document with 5 ditaa diagrams, and exporting my
Org file is taking quite a long time, about 10 seconds to compile 5
ditaa diagrams + HTML export.

At the moment, even if I don't modify any of the ditaa ASCII, all 5
are compiled from ASCII to a PNG. Is there a way ask ditaa to only
generate a new PNG file if the contents of the `#+BEGIN_SRC ditaa`
have changed?

Thanks,

--
Rob

  I think you want to look at caching:

    Thanks for the tip. Interestingly, caching doesn't seem to work for
    ditaa blocks. E.g.
    
    --8<---------------cut here---------------start------------->8---
    #+BEGIN_SRC ditaa :file images/hello-world-round.png :cache yes
    +--------------+
    |              |
    | Hello World! |
    |              |
    +--------------+
    #+END_SRC
    --8<---------------cut here---------------end--------------->8---
    
    Run the ditaa.jar file every time I export to HTML with `C-c C-e h h`.
    
    Does `:cache yes` only work for particular source languages?

      Caching with ditaa works for me with Emacs 24.4.1 and Org
      8.2.10-37-gc000e8-elpaplus.
      
      What versions of Org/Emacs are you using?
      
      Cheers,
      
      Loris

          Use org-babel-execute-src-block or org-babel-execute-buffer first to get 
          the results and the cache sha in your buffer.
          
          The exporter runs babel in a copy buffer, so caching done there is 
          irrelevant.
          
          HTH,
