[babel] double quotes in tables

[babel] double quotes in tables

[Francesco Pizzolante]

Hi,

Often, I find useful that babel could generate result tables without the
double quotes (") enclosing all the text values in the cells.

In order to do that, I added a 'noquotes` option to the :results header
argument.

Here's my patch. As I'm not an elisp expert, please tell me if there's a
better/safer way to do that or maybe that it already exists an option to do
that...

Re: [babel] double quotes in tables

[Eric Schulte]

Hi Francesco,

Thanks for bringing this up.  I'm thinking that a more aggressive
version of your patch should be applied here.  It seems that org-babel
should not change the values of tables which pass through it.  I'm
leaning towards applying the following lines of your patch

-			     '(:fmt (lambda (cell) (format "%S" cell)))) "\n"))
+			     '(:fmt (lambda (cell) (format outputformat cell)))) "\n"))

That change doesn't seem to break any of our unit tests.

Can anyone think of a reason not to make this change?

Thanks -- Eric
