* [babel] howto debug #+call lines

Hi all,

(seems like I am having trouble to post -- sorry if multiple copies of
this end up on the list)

I am getting different results from the evaluation of a source block and
the evaluation of a #+call line to that block.

Therefore, my question: Is there an equivalent to
org-babel-expand-src-block (C-c C-v v) for #+call lines?

Or more general:  How do I debug #+call lines?

Regards,
Andreas

That's plagiarism.  You should cite Bastien here :)

Thanks for the pointers.  Let's see whether I'll find time.  Should not
be hard even with my elisp "skills".

Patches are always welcome. :)

The call line is evaluated by first expanding itself into a full code
block, so perhaps you could add functionality to C-c C-v v so that it
will expand this ephemeral code block.  Additionally it may be easy to
update C-c C-v I so that it works on call lines, which may provide the
information you're after.

Best,

Thanks for the confirmation, that there is no possibility to expand a
#+call line.

I know, that I can jump to the code block and expand that one (quite
fast with C-c C-v g RET C-c C-v v), but that is exactly *not* what I was
looking for.  Because then, the header arguments to the source code
block will apply instead of the header arguments to the #+call line.

I was hoping for a C-c C-v v on #+call lines, which would spare me from
modifying the source block's header arguments.  But it is not a pressing
issue, just my laziness (and bad coding perhaps).

Regards,
Andreas

There is no body to expand in a call line so C-c C-v v would have
nothing to show.  You can however jump to the related code block and
call C-c C-v v there.  This process could be made faster by wrapping the
org-babel-goto-named-src-block and org-babel-expand-src-block functions
into a single function.

Thanks for following this up.  I found the problem in my case:  The
header argument ':colnames yes' was missing from the call line, such that
the passed variables were different.  (I've fallen into that trap
repeatedly, but do not learn, as it seems...)

It would have been a lot easier to find this, if I had had the possibility
to do C-c C-v v on the call line to get the chance to step through the
(R-) code that is evaluated.  Without this, it took me some time to
figure things out.

So the question still stands: Is there the possibility to see what is
actually executed with a call line, similar to C-c C-v v on a source
block?

For a small example consider:

---
#+name: foo
| bar |
| baz |
| bam |

#+call: testblock[:var a=foo]() :colnames yes

#+name: testblock
#+begin_src R :var a=foo :colnames yes
  a <- a[,1]
  data.frame(x=a)
#+end_src
---

Regards,
Andreas

Can you provide a minimal example?

You could write a code block equivalent to the call line.  E.g.,

    #+call: foo(bar=1)

is equivalent to

    #+begin_src emacs-lisp :var results=foo(bar=1)
      results
    #+end_src

Hi all,

I am getting different results from the evaluation of a source block and
the evaluation of a #+call line to that block.

Therefore, my question: Is there an equivalent to
org-babel-expand-src-block (C-c C-v v) for #+call lines?

Or more general:  How do I debug #+call lines?

Regards,
Andreas
