Re: [Orgmode] Correct babel format for ditaa?

[John Hendy]

Thanks Eric... I should have included that my .emacs file has the following (which I followed from here: http://orgmode.org/Changes.html#ob-configuration-changes):

;; setup ditaa

(setq org-ditaa-jar-path "~/.elisp/org.git/contrib/scripts/ditaa.jar")

(org-babel-do-load-languages

 'org-babel-load-languages

 '((ditaa . t)

   (gnuplot . t)))

(require 'ob-ditaa)

If I understand correctly, the (ditaa . t) and (require 'ob-ditaa) are redundant but since it wasn't working, I tried both. Is this what I need to have babel work with ditaa?

Thanks for any input...

John

Hi John,

Yes, (1) below is the preferred format, however the "ditaa" language is
not enabled by default.  Please customize the org-babel-load-languages
variable to enable support for evaluating ditaa code blocks, and then
try the code block syntax mentioned in (1) below again and a ditaa
figure should be successfully exported.

A benefit of the (1) (aka Babel) method below is that code blocks can be
evaluated "live" from inside the Org-mode buffer with C-c C-c.  See
Chapter 14 of the manual or the relevant portion of the quick guide
http://orgmode.org/guide/Working-With-Source-Code.html for more
information on using Babel.

Best -- Eric
