[new exporter] Captions for tables made by source blocks

[new exporter] Captions for tables made by source blocks

[Vikas Rawal]

There has been some change in the behaviour of #+CAPTION in case of
tables made by source blocks. In the old exporter, #+CAPTION just
before #+BEGIN_SRC was sufficient to place the caption before the
table when the file was exported.

The new exporter does not produce captions the same way.

When I looked through the list archives, I found some discussion (
http://list-archives.org/2012/08/20/emacs-orgmode-gnu-org/o-new-exporter-and-latex-attributes/f/2837855005,
and http://www.mail-archive.com/emacs-orgmode@gnu.org/msg57188.html )

It is, however, not clear if the problem was finally resolved and what
is the recommended practice. Could somebody explain?

CAPTION keyword above a source block applies to the source block only.
If the source block generates a table, you have to put a CAPTION above
it, as it will not inherit the caption of the source block.

It also implies that you need to name the results. Otherwise, source
block will not recognize its own production, due to the CAPTION keyword
above it.

HTH,

Thank you once again Nicolas. 

I understand from this that the variable org-babel-results-keyword has
to be changed to NAME. I did this and it works.

Is there a way that this could be file-specific?

I wasn't clear. By "naming the results", I mean that you must provide
your source block a "#+NAME: something" attribute, so the generated
table gets a "#+RESULTS: something" attribute.

BTW, you mustn't change `org-babel-results-keyword'. I don't even know
why this is a defcustom and why it is allowed to turn it into "NAME".
RESULTS refers to the name of the src-block which produced the current
element, whereas NAME refers to the name of the current element. Their
purpose is completely different.

Cc'ing Eric Schulte about it.

Have changed `org-babel-results-keyword' back to RESULTS. The captions
are working fine. Thank you.

Let us hear from Eric what is the purpose of this variable, and if it
has some use.

IIRC, that was introduced to allow users to choose #+results or
#+Results.

Interesting that this topic comes up today just as I noticed it. I'm still
unclear about how to put the CAPTION keyword in when using a dynamic block
via org-collector.el.

I have the lines below and I do not get a table caption like I used to in
the old exporter.

#+NAME: tbl-coi
#+CAPTION: COI Table
#+BEGIN: propview :colnames ( "Area" "Shorthand" "COI" ) :cols ( AREA
CATEGORY ITEM ) :match "+COI+LEVEL=2-ARCHIVE" :noquote t :scope agenda
:inherit (AREA)

For the same reason, caption here applies to the dynamic block, not to
its contents.

The usual way to handle it is to provide a :caption argument in the
header, which will in turn create a "#+CAPTION" keyword above the table
upon updating.

However, I don't think that org-collector handles it. You may want to
patch it (you can look at `org-clocktable-write-default' for an
example).

There is something strange happening. Cross-references to captions of
tables that are produced thus get exported to latex as
\texttt{something} rather than as \ref{something}.

Am not able to figure out what have I missed up. It was working fine
yesterday but then [perhaps] I did something.

I have always used something along these lines

#+label: crop-median

just before the table to define the target.  This works for your ECM.

This is odd!! Please see the .tex file attached with this mail. This
is what I get. Any idea, how do I debug this?

For me, it works if I change the value of org-babel-results-keyword
to NAME. Then the results block is produced with  #+NAME: crop-median

The cross-reference picks this up fine. 

But when org-babel-results-keyword is set to RESULTS, the results
block is produced with #+RESULTS: crop-median

The cross-reference does not pick it up correctly. The latex backend
does not export it with a \ref but with a \texttt. The odt backend
also produces "crop-median" in cross-reference rather than the table
number.

This seems to be a common enough mistake and it is currently impossible
to put captions and other arguments on results blocks save with yet
another source block that produces the correct org code (well you can
put the headers there after the result has been generated, but then you
have to delete all that stuff before generating a new result).

Would it be possible to either change the insertion of the results so
that the user has a chance to put any options before the place where it
should go or (I'm not fond of that idea, but I'll put it out there
anyway) have yet more option arguments (along the lines of
#+RESULTS_HEADER…) that will be transferred to the results block along
with the actual result?

Achim.

It's very easy to have a caption on the generated output: name the code.
Hence, the following code block:

  #+NAME: calculation
  #+BEGIN_SRC emacs-lisp
  (+ 1 1)
  #+END_SRC

will produce:

  #+RESULTS: calculation
  2

If you add a caption to the results, like:

  #+CAPTION: Basic arithmetic
  #+RESULTS: calculation
  2

you can update the source block without ever needing to remove the
caption.

At some point, it would be nice if Babel could find captioned anonymous
results (so you wouldn't even have to name the block). I'll have a look
at it. But meanwhile, this solution is sufficient.

Great.  I could swear the last time I was trying this it would add a new
result block on top of the old one, but I may have changed the name
inbetween.  It would still be nice (I think) if an unnamed source block would
simply replace the next unnamed result block if there is one.

The thing is:

- you try with an unnamed block
- you get an unnamed result block inserted
- you name the block
- you get a named result block inserted
- you have to manually remove the unnamed result block

> It would still be nice (I think) if an unnamed source block would

I think this is a great proposition, which would make a lot of sense.
