Dear List,
This
#+BEGIN_SRC sh
echo "a b c d"
echo "1 2 3 4"
echo "5 6 7 8"
#+END_SRC
produces this:
#+RESULTS:
| a | b | c | d |
| 1 | 2 | 3 | 4 |
| 5 | 6 | 7 | 8 |
How do I get this
#+RESULTS:
| a | b | c | d |
|-----+---+---+---|
| 1 | 2 | 3 | 4 |
| 5 | 6 | 7 | 8 |
?
Thanks,
Loris

You really don't want to use a shell for that, but if you insist, this
would do it:
--8<---------------cut here---------------start------------->8---
#+BEGIN_SRC sh :results raw
exec 3>&1 >&-
(
echo "a b c d"
echo ""
echo "1 2 3 4"
echo "5 6 7 8"
) | sed -re 's/^| /|/g' -e 's/^\|$/|-/' >&3
#+END_SRC
--8<---------------cut here---------------end--------------->8---
Regards,
Achim.

Looking at this again, of course this simpler version would do the same.

You might find use of the post header argument here,
http://orgmode.org/manual/post.html
In this case it's as simple as this
#+NAME: add_hline
#+BEGIN_SRC emacs-lisp :var data='((a b c)) h1=1
(require 'cl)
(append (subseq data 0 h1 ) (list 'hline) (subseq data h1))
#+END_SRC
#+BEGIN_SRC sh :post add_hline(data=*this*)
echo "a b c d"
echo "1 2 3 4"
echo "5 6 7 8"
#+END_SRC
Probably you can remove the require 'cl. Also, you can generalize the
code to take arbitrarily hline positions.
Hope it helps.

Here's a more fun :post function (again depending on cl).
#+NAME: add_hline
#+BEGIN_SRC emacs-lisp :var data='((a b c) (d e f) (h i j)) h='(0 -2 100 last)
(let* ((d (copy-list data))
(h0 (delq nil
(mapcar (lambda (e)
(when (or (not (numberp e)) (< (abs e) (length data)))
(cond
((equal e 'last) (length data))
((and (numberp e) (< e 0)) (+ (length data) e))
(t e))))
(if (listp h) h (list h)))))
(h1 (number-sequence 0 (1- (length h0))))
(H (mapcar* '+ h0 h1)))
(dolist (x H) (push 'hline (nthcdr x d)))
d)
#+END_SRC
#+BEGIN_SRC sh :post add_hline(data=*this*, h='(0 1 last))
echo "a b c d"
echo "1 2 3 4"
echo "5 6 7 8"
#+END_SRC
#+RESULTS:
|---+---+---+---|
| a | b | c | d |
|---+---+---+---|
| 1 | 2 | 3 | 4 |

Oops, my example was obviously a little too simple. What I am actually doing
is something like this:
#+NAME: current_data
#+BEGIN_SRC sh :dir /home/loris/remote/far/far/away/results
echo "step level time clicks"
grep statistics *.log | awk '{print $(NF-9),"\t",$(NF-6),"\t",$(NF-4),"\t",$(NF-1)}'
#+END_SRC
So Achim's suggestion of using ":results raw" might be the way to go
(once I've worked out what the sed bit is doing ...)
However, the table will ultimately be around 40000 lines long,
so from a performance point of view it would be nice not to have to pipe
the whole thing through sed, particularly as the files are on a remote
server. Having said that though, it is not a performance-critical
application.
So maybe I'll look at Rasmus' simpler suggestion (my lisp skill are
unfortunately not quite up to the "fun" variant ...)
How complex would the elisp version of my grep and awk above be? Just
having one code block would be a little neater from my point of view.
Thanks for all the help.
Cheers,
Loris

The "fun" variant works with any table. You just specify a list of
positions where you want hlines, e.g. '(0 1 last) or '(0 1 -1).

If you use :post you can keep your utility functions in a :noexport:
section at the bottom of your file (or even in a library-of-babel (see
org-babel-lob-ingest)) and you don't litter your code with unnecessary
stuff. It's also usable across blocks.

How about
#+NAME: current_data
#+BEGIN_SRC sh :dir /home/loris/remote/far/far/away/results :colnames '(step level time clicks)
grep statistics *.log | awk '{print $(NF-9),"\t",$(NF-6),"\t",$(NF-4),"\t",$(NF-1)}'
#+END_SRC
or do the column names need to be generated by the code block?

No, the column names are fixed, so that's perfect, thank you. I
suspected there might be some more straight-forward way than the
interesting, but slightly more involved methods suggested by Achim and
Rasmus.
However, it is good have some examples for ":results raw" and ":post"
and I shall certainly be looking into "Library of Babel", as I seem to
be sliding gradually into programming in Org.
Cheers,
Loris

And if you are generating this programatically, this works:
#+BEGIN_SRC sh :results raw
(
echo "|a |b |c |d"
echo "|-"
echo "|1 |2 |3 |4"
echo "|5 |6 |7 |8"
)
#+END_SRC

There might be way to do that, but it's not implemented for shell blocks
since there isn't an easy way to deal with arrays in a shell. You'd be
much better off using a language that has support for that (like Perl).
In your case (when the first line is always a header and you don't need
hlines anywhere else), the following trick using the end header
arguments of a call line works just as well:
--8<---------------cut here---------------start------------->8---
#+NAME: table
#+BEGIN_SRC sh :results table
echo "a b c d"
echo "1 2 3 4"
echo "5 6 7 8"
#+END_SRC
#+CALL: table() :results table :colnames yes
#+RESULTS:
| a | b | c | d |
|---+---+---+---|
| 1 | 2 | 3 | 4 |
| 5 | 6 | 7 | 8 |
--8<---------------cut here---------------end--------------->8---

Achim.
