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.

Hi Carsten, That sounds like a very good idea. 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.

While this would be my preference, it is certainly not my decision to make, and I honestly haven't given it much thought up until this point. From your post yesterday, without looking closer at org-babel, it sounded to me that it is still under heavy development, so maybe it is too early for the core at this moment? Yes, I am very much in agreement that it is too soon to contemplate moving org-babel into the core. The intended point of my aside above is that I don't plan on adding interactive evaluation directly to org-exp-blocks.
