Subject: How to get a table into a variable in a shell code block?
Date: Sat, 3 Apr 2021 14:14:56 -0400 (EDT)	[thread overview]
Message-ID: <alpine.DEB.2.22.394.2104031407290.101059@shell3.miskatonic.org> (raw)

Let's say I have a table like this:

#+NAME: numbers
| one   |
| two   |
| three |

I want to run through those numbers in a shell code block, but it I pass in 
table as a variable, it only sees the first number.

#+begin_src shell :results output :var n=numbers
echo $n

: one

In Ruby it sees the numbers as an array:

#+begin_src ruby :results output :var n=numbers
puts n
puts n.class

: one
: two
: three
: Array

And in R sees them as a data.table with one column.  Both are very easy to 
iterate over, of course.

I looked at the docs, but didn't see this covered, then I looked at ob-shell.el 
and saw the "org-babel--variable-assignments:bash_array" function, which might 
or might not be relevant, but it's all beyond my comprehension.

Is there a way to get my shell code seeing all of the elements in the column?
