Computing the value of some cells of a table using a named code block

Computing the value of some cells of a table using a named code block

[Alan Schmitt]

Hello,

I have a table that summarizes my monthly budget, and I would like to
add a column where I compute my actual spending. I can get this
information using a shell script, but I don't know how to integrate it
in the table.

Here is a contrived example:
--8<---------------cut here---------------start------------->8---
#+name: spending
#+begin_src sh :var category="foo"
echo $category
#+end_src

| Category | Budget | Spending |
|----------+--------+----------|
| Food     |   1000 |          |
| Rent     |   1000 |          |
#+TBLFM: $3=call_spending("$1")
--8<---------------cut here---------------end--------------->8---

My question is: how do I write the TBLFM so that every cell of column
3 is the result of call the named block with column 1 as argument?

Thanks,

Alan

When there is no named source block involved I use just

| Category | Budget | Spending |
|----------+--------+----------|
| Food     |   1000 | Food     |
| Rent     |   1000 | Rent     |
#+TBLFM: $3 = '(org-trim (shell-command-to-string (concat "echo " $1)))

For named source blocks there is sbe, see Worg.

This is most useful, thanks a lot!

For the record, here is the solution using org-sbe:

--8<---------------cut here---------------start------------->8---
#+name: spending
#+begin_src sh :var c="bar" :results silent
expr $c
#+end_src

| Category | Budget | Spending |
|----------+--------+----------|
| Food     |   1000 | Food     |
| Rent     |   1000 | Rent     |
#+TBLFM: $3='(org-sbe "spending" (c (concat "\"" $1 "\"")))
--8<---------------cut here---------------end--------------->8---

Thanks again,

Alan
