hmm, I just pushed the actual ob-calc.el file up to the repository. Do
you still get these errors if you loaf up calc support through calling
(require 'ob-calc)?

Yes, I guess so. My initial thoughts were that we have plenty of
algebraic languages available already through babel (octave, R, python,
...) so why not support a stack based one more directly. However, the
real benefit of calc is that it is *emacs* and not external! Algebraic
is more natural to most people so making it easy for them to express
themselves makes sense.

Alright,
I've just pushed up support for variables. The following should all
work as expected (or at least as I would expect them to). Note that
most all of these blocks would have an effect on the calc stack. I
think the next step would be to allow different sessions to specify
different stacks.
** playing with calc support
#+begin_src emacs-lisp :results silent
(require 'ob-calc)
#+end_src
#+begin_src calc :var some=8
some
some
'*
1
'+
#+end_src
#+results:
: 65
#+begin_src calc
2*(8+8)
#+end_src
#+results:
: 32
#+begin_src calc
2*e
#+end_src
#+results:
: 5.43656365692
#+begin_src calc :var something=9
2*something
#+end_src
#+results:
: 18
There are very likely some bugs, and as always I'm eager for a calc
power user to show me the light of how this support could be make more
"calc idiomatic".

There must be something stupid in my config, but even a simple one like the
following does not work for me:
#+begin_src calc
1
2
'+
#+end_src
Error is:
#+begin_src emacs-lisp
executing Calc code block...
calc-push-list: Symbol's value as variable is void: calc-command-flags
#+end_src
Though, I confirm you that I have loaded both =calc= and =ob-calc=... Any idea?

Be hopeless: I won't be that one ;-(

That variable is defined in my version of calc.el (distributed with the
latest version of Emacs from git). Is that variable not defined in your
calc.el file? Maybe the solution is to upgrade your calc.

I have "GNU Emacs 23.1.50.1 (i386-mingw-nt5.1.2600) of 2009-10-14 on
LENNART-69DE564 (patched)" (known as EmacsW32, latest version that Lennart put
online).
Library is file "c:/Program Files/Emacs/emacs/lisp/calc/calc.elc", and I see
(on line 1544 of the =.el= file):
#+begin_src emacs-lisp
(defvar calc-command-flags)
#+end_src
ELC seems well compiled from that EL, as times report:
--8<---------------cut here---------------start------------->8---
-rw-rw-rw- 1 Fabrice Aucun 138805 2009-10-14 02:45 calc.el
-rw-rw-rw- 1 Fabrice Aucun 103841 2009-10-14 02:46 calc.elc
--8<---------------cut here---------------end--------------->8---
Setting it myself to nil -- I have no idea why I must do this! -- :
#+begin_src emacs-lisp
(setq calc-command-flags nil)
#+end_src
has the effect that many examples now work.
Not all, though. For example,
#+begin_src calc
2*e
#+end_src
returns =nil=:
#+results:
: nil

Seb

Hmm, that is weird. I guess you could search for the text variable name
in your calc.el file, but I don't know how that would help you. Since
I'm requiring calc from ob-calc.el, and I am only calling existing calc
functions I'm going to treat this as a calc bug (i.e. beyond my scope).

That is the only example I gave that uses a calc default variable.
Maybe this is also a difference in our calc implementations?

Any idea why variables inside of parentheses don't work, but variables

Further on this, any suggestions on how to pass a vector variable to
calc using babel? I tried
#+begin-src org
#+begin_src calc :var y=[1 2 3]
3 y
#+end_src
#+end_src
but get an error that says
: Bad format in variable contents: Expected a number
I've tried putting the vector in quotes but that doesn't help either.
Is this maybe not possible?
Thanks,
eric

With the newest version of Org-mode, I'm now getting the following
output.
#+begin_src calc :var y=[1 2 3]
3 y
#+end_src
#+results:
: (3, 6)
Does this look correct?

This does not look correct: assuming my knowledge of calc is correct,
the result should be the scalar 3 multiplied by each of the vector
elements. I don't understand how =(3, 6)= can be the output of =3 y=...
The strange thing is that this doesn't work at all for me (with git as
of a few minutes ago): I still get the error message
: byte-code: Bad format in variable contents: Expected a number
However, if I put the vector in double quotes, it works:
--8<---------------cut here---------------start------------->8---
#+begin_src calc :var y="[1 2 3]"
3 y
#+end_src
#+results:
: [3, 6, 9]
--8<---------------cut here---------------end--------------->8---
*but* if I subsequently remove the double quotes, it doesn't work and if
put them back, it no longer works either. I am confused... there's
like a hysteresis loop in org babel :(
Any suggestions on how to debug this are welcome, of course.

Oh, I just got an even stranger result, with the latest from git...
#+begin_src calc :var y=[1 2 3]
3 y
#+end_src
#+results:
: 3 hline
something is most certainly wrong...
Alright, I've made two changes, first, it is now possible to pass elisp
vectors through to code blocks, e.g.,
#+begin_src emacs-lisp :var data=[1 2 3]
(elt data 1)
#+end_src
#+results:
: 2
Second, I've added a slightly hackey but seemingly necessary
post-processing step to a call to calc-eval in ob-calc to remove quotes
from vectors. This allows vector processing to take place---at least as
far as my limited calc knowledge is concerned. For example;
#+begin_src calc :var y=[1 2 3]
3 y
#+end_src
#+results:
: [3, 6, 9]
Hope this helps -- Cheers -- Eric

It does indeed. It all seems to work just fine now.
I don't necessarily know much more emacs calc than you but the little I
know seems to work just fine. It's such a powerful package sitting
there mostly idle and org babel is probably the best way to release it
for general use! Especially for inline calculations... Time to re-read
the calc manual again and play.
Thanks,
eric

Indeed. Embedded mode is excellent and there is some overlap with what
babel provides. I like them both.

Indeed. Works very well. Thanks!
