As an example, assume that I have manully created a diagram with ditaa code, and once I am finishede diting I'd like to press a keystroke e.g. Ctrl-C Ctrl-C and have the contents change to the generated output image, and the ditaa code will be hidden. When subsequently navigating to the image there should be some indicator that this is a generated image and some keystroke should allow turning the image back to its source code. The same idea could be used for any system generating images, e.g. LaTeX formulas, asymptote, a python script using cairo, etc. Similarly if the source code is svg I might not want to display the source code at all (which might be large), but would like to invoke inkscape to edit the svg data. This is better done by referencing the svg as an external image, instead of having it inline, but I would still like to easily invoke an editor application from within emacs with a simple keystroke. So is this currently possible?

This will insert a link to the generated image into your Org-mode file. If you then turn on inline images with M-x org-toggle-inline-images you can preview the generated image from within your Org-mode buffer.

Hi Dov, Following on from the above, you can make the images in the emacs buffer automatically refresh[1] after execution with (add-hook 'org-babel-after-execute-hook 'org-display-inline-images) Dan Footnotes: [1] On reading the docstring, one might think that this would be the right code, but it doesn't seem to refresh the image: (add-hook 'org-babel-after-execute-hook (lambda () (org-display-inline-images nil t))) > > For more information on code blocks see > http://orgmode.org/manual/Working-With-Source-Code.html#Working-With-Source-Code > > Best -- Eric > > Dov Grobgeld <dov.grobgeld@gmail.com> writes: > >> Thanks!

This is exactly what I was looking for.

Hi Dov, Yes, see the documentation of the :exports header argument. http://orgmode.org/manual/Exporting-code-blocks.html#Exporting-code-blocks Header arguments such as :exports can be set in various different ways. http://orgmode.org/manual/Using-header-arguments.html#Using-header-arguments The difference in behavior you see stems from the value of the variable org-babel-default-header-args, and the language-specific versions of that variable. Note below that although :exports in general defaults to "code", for ditaa this default is overridden to "results". The reason for which was that ditaa code is typically going to be there to generate graphics, whereas that is only occasionally true for python. #+begin_src emacs-lisp :results pp org-babel-default-header-args #+end_src #+results: : ((:session . "none") : (:results . "replace") : (:exports . "code") : (:cache . "no") : (:noweb . "no") : (:hlines . "no") : (:tangle . "no")) #+begin_src emacs-lisp :results pp org-babel-default-header-args:ditaa #+end_src #+results: : ((:results . "file") : (:exports . "results")) #+begin_src emacs-lisp :results pp org-babel-default-header-args:python #+end_src #+results: : nil Dan > > Thanks! > Dov > > > On Sun, Nov 28, 2010 at 19:27, Dan Davison <dandavison7@gmail.com> wrote: > >> (add-hook 'org-babel-after-execute-hook >> (lambda () (org-display-inline-images nil t))) >> > _______________________________________________ > Emacs-orgmode mailing list > Please use `Reply All' to send replies to the list. > Emacs-orgmode@gnu.org > http://lists.gnu.org/mailman/listinfo/emacs-orgmode ^ permalink raw reply [flat|nested] 7+ messages in thread
