Currently Org-babel caches results using a much simpler scheme (only run the block if there are no results in the buffer), but what you recommend would be an efficient way of noticing if the command has changed. When discussing this previously we had only considered approaches using the date of execution. I'll add this idea to the org-babel tasks. Thanks! -- Eric ps. does Org-mode already have a method of generating sha1 hashes? I just did an `elisp-index-search' for sha1 and nothing came up. > > - Carsten > > On Aug 27, 2009, at 8:51 PM, Eric Schulte wrote: > >> I don't have any plans to add previewing to org-exp-blocks, however >> there is an alternative. >> >> Org-babel provides for the evaluation and viewing of the results of >> blocks in Org-mode documents.

Re: [Orgmode] org-exp-blocks: what about previewing blocks ?
Hi Eric, this sounds like a great alternative, thanks. I wonder if we should consider some cashing of images, also for export. I think we could have an alist with sha1 hashes as keys and image files as values. The sha1 hash could be made from the entire code and the command that is used to create the image.. - Carsten On Aug 27, 2009, at 8:51 PM, Eric Schulte wrote: I don't have any plans to add previewing to org-exp-blocks, however there is an alternative. Org-babel provides for the evaluation and viewing of the results of blocks in Org-mode documents. As such, it is possible to use Org- babel to preview the output of blocks. For example, with Org-babel installed [1] calling C-c C-c on the following block will evaluate the block placing a link to the resulting file into the Org-mode document.

Re: [Orgmode] org-exp-blocks: what about previewing blocks ?
I don't have any plans to add previewing to org-exp-blocks, however there is an alternative. Org-babel provides for the evaluation and viewing of the results of blocks in Org-mode documents. As such, it is possible to use Org-babel to preview the output of blocks. For example, with Org-babel installed [1] calling C-c C-c on the following block will evaluate the block placing a link to the resulting file into the Org-mode document. Subsequently calling C-c C-o with the point on the block will find the link and open it previewing the image. --8<---cut here---start->8--- #+begin_src ditaa :file images/blue.png :cmdline -r +-+ | cBLU| | | |++ ||cPNK| ||| +++ #+end_src --8<---cut here---end--->8--- Hopefully in the near future Org-babel should be stable enough to justify an initial release, which should include an instructional page on worg.
