Hello,
this is a very low priority request so please feel free to ignore or put
at the bottom of what I'm sure is a long list of TODOs...
I have a data table. In different code blocks, I need to access
different sets of columns (or rows) from this table. At present, I am
passing the whole table to the code blocks and then extracting the
columns (or rows) within the code. However, it would be nice if I could
specify the actual column I want directly in the :var header argument,
such as
: #+begin_src octave :var data=mytable[0:-1;1:3,5:6]
where I've used a semi-colon to separate dimension indices and used a
comma to separate multiple ranges within an index. This, I realise, is
a change to the current syntax... but I'm doing this just for
illustration.
As I said, I have a workaround so this is indeed a low priority request!
Thanks,
eric

Hi Eric,
Unfortunately I recently became very busy, so I will not be able to
address this any time soon. However, the indexing behavior is self
contained in the `org-babel-ref-index-list' function, so feel free to
take a crack at that function. If you are able to implement your syntax
as described below I would be happy to help fold in the change.
Cheers -- Eric

Hi Eric. That's perfectly fine! I completely understand. As I said,
it's a very low priority request.

I will do so, i.e. attempt it, but don't hold your breath ;-) my elisp
capabilities may not be up to it but it sounds like a good project for
the summer...
thanks,
eric
