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.
