Re: [Orgmode] Re: Suppressing src block evaluationon publish?
Hi all, sorry to reopen this thread, but this does not work for me (GNU Emacs 23.2.1, Org almost HEAD c7700d7bbee4f7596feb199b1ec1bc7750d4fb48) For me the image in the attached example is always created during (LaTeX)export. Even if I do the manual evaluation once (and the hash is created). The manual re-evaluation respects the :cache yes and does not evaluate again.

It does seem that it would be nice if in this situation, the first export added the SHA1s, and subsequent exports recognized that evaluation wasn't required. I think the reason this does not happen is that behind-the-scenes Org makes a copy of the buffer for export preprocessing (including src block evaluation). But Eric S is the expert -- he may have more to say here. A couple of things that might be relevant here: the variable `org-export-babel-evaluate' can also be used to prevent evaluation on export (but the :cache approach has advantages). And C-c C-v C-b / C-c C-v C-s (`org-babel-evaluate-buffer' / `org-babel-execute-subtree') could be used to update the SHA1s. > Perhaps the documentation of :cache could be extended to mention the > necessity of evaluating the source block before exporting.

There is a slight gotcha here, though. I added :cache yes to the source headers and exported again, but nothing changed; all the images were generated again. Also, no SHA1 hash was added to the +results header. After some fruitless fiddling I was about to write to the list again and moan, when I did a slightly random C-c C-c in the begin_src line and, hey presto, the hash was added to the results header. I then did this for all the images and found that the image were no longer regenerated on export, as advertised. Perhaps the documentation of :cache could be extended to mention the necessity of evaluating the source block before exporting.
