When src block result is an image, how to define caption, html and latex attributes ?

When src block result is an image, how to define caption, html and latex attributes ?

[Sébastien Gendre]

Hello,


When a source block create a result who is an image, how can I define
the #+CAPTION, #+LATEX_ATTR and #+HTML_ATTR of this image ?

If I add them manually after the result generation, and generate again
the result, the #+CAPTION, #+LATEX_ATTR and #+HTML_ATTR are moved after
the result.

In org-babel documentation, I didn't found any header argument like
":result-caption" or something similar. There is a post processing, but
I cannot found the list of available post processing actions and their
config.


Best regards

I am unable to reproduce. The updated result does not displace the
affiliated keywords on my side, using the latest main and the latest
stable Org mode version.

Does this happen if your src block is NAMEd?

If I place the #+CAPTION: and #+HTML_ATTR before the #+RESULTS:, then
generate again the result of the source block, I got a new #+RESULTS: on
top of the previous and its caption and html attributes.

Example, before regenerate the source block result:



#+CAPTION: Test image
#+HTML_ATTR: :width 30px
#+RESULTS:
[[file:images/simple-test.png]]



And after regenerate the source block result:



#+RESULTS:
[[file:images/simple-test.png]]

#+CAPTION: Test image
#+HTML_ATTR: :width 30px
#+RESULTS:
[[file:images/simple-test.png]]



My version of Org-mode is 9.6.15

If I name the source block, it work.

Is it because:

* When a source block is named, it's result is also named

* When a result is named, Org-mode can locate it and replace its value

* But when a result is not named, Org-mode insert a #+RESULTS: just
  after the block and create a new one if it cannot found the previous
  one right after the block

?

You have a typo in one of the affiliated keywords.
Should be

#+ATTR_HTML: :width 30px

#+HTML_ATTR: is a very different construct - a full keyword rather than
affiliated keyword. So Org mode sees your

#+CAPTION: Test image
#+HTML_ATTR: :width 30px

and then 

#+RESULTS:
[[file:images/simple-test.png]]

as two separate paragraph-like elements, while babel is only looking at
the first following elements for an existing result when the block is
not named.

P.S.

We should really indicate the difference between normal and affiliated
keywords better.

You are not the first person stumbling upon this exact wrinkle with src
block results. So, it would be nice to address it somehow.

Yes, pretty much my understanding.  I tend to name every src block
anyway as it makes navigation easier (using
org-babel-goto-named-src-block).

I didn't know this function exist. Thank you very much. :)
