Hi everyone,
I'm trying to get my head around babel and getting info back into a
table.
The below org file tracks expenses and the perl code simply sums them
up.
The code is working but I now want to get the total back into another table. What I have is not
working can someone tell me what I'm doing wrong here?
Cheers
Bart
* Expenses

| 2010-07-27 | umart - video card, kvm, speakers | 136 |
* Code
#+srcname: totals
#+begin_src perl :var details=expenses[1:-1]
my $total = 0;
foreach my $row (@$details) {
$total += @$row[2];
}
return $total;
#+end_src

Hi Bart,
You've mixed up #+call and sbe there. sbe is what you want to use in a
table formula; #+call and #+lob are for standalone lines. Here are a few
examples of different ways to do what you're doing. Hopefully they make
things clear.

--8<---------------cut here---------------start------------->8---
* Totals
** Using a table formula
*** Relying on default argument to totals block
| Total | 155 |
#+TBLFM: $2='(sbe "totals")
*** Providing argument explicitly
The dots are a bug. We'll fix it.
**** version 1
| Total | 155... |
#+TBLFM: $2='(sbe "totals(details=expenses[1:-1])")
**** version 2
| Total | 155... |
#+TBLFM: $2='(sbe "totals" (details "expenses[1:-1]"))
** Using call/lob
#+call and #+lob are synonyms
*** Relying on default argument to totals block
#+call: totals()
#+results: totals()
: 155
or equivalently (it outputs into the same results block):
#+lob: totals()
*** Providing argument explicitly
#+call: totals(details=expenses[1:-1])
#+results: totals(details=expenses[1:-1])
: 155

Dan,
Thank you very much for that explanation!
This makes the whole thing much clearer.
Do you know where the sbe call is documented in the manual? I couldn't
find it my self.
Thanks again.

It's documented in the original Worg pages here
http://orgmode.org/worg/org-contrib/babel/intro.php#spreadsheet
but you're right, it looks like that information is completely lacking
from the manual. I've added it as a babel development TODO.
Thanks for pointing that out,
Dan
