Hi all,
currently the code in org-exp-blocks is intended for pre-processing
only.
It seems to me like org-mode would gain a very powerful feature, if
blocks could also be previewed in their own buffer, using the same
mechanism as the org-format-latex function.
What do you think ?
I don't see how this could be done in a general way. I guess you
mean in particular
the graphics blocks like ditaa?
Yes. For any block type bt, if it makes sense, it would be possible
to write such org-block-<bt>-generate-image(body) that takes the
block as argument and returns the path of the image it produced.
Then:
- for exporting: the existing org-export-blocks-format-<bt>
functions would simply call their respective
org-block-<bt>-generate-
image and work the same ;
- for previewing a block of type <bt>: if such org-block-<bt>-
generate-image exists, call it and display it the same way org-
format-latex does
Wouldn't it be great ?
Yes, it would be. First you will need to talk Eric Schulte into
splitting the image generation functions into separate functions.
The I could look into the preview functionality.
I recently sent out an email announcement of development on org-babel
which should provide a unified backend for evaluating source-code
contained in org-mode blocks. If org-exp-blocks is using org-babel
for
it's source-code evaluation the ability to interactively evaluate
blocks
will come for free. This would be my preference rather than
implementing a new code-evaluation schema for org-exp-blocks.
I suppose that this would assume that org-babel is accepted into the
core of org-mode (for it to be a requirement of org-exp-blocks which
is
now part of the org-mode core). 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.
