Re: Possible Calc support for Org-Babel?

[Eric S Fraga <ucecesf@ucl.ac.uk>]

Eric,

This is really nice!

I had a problem initially in that calc-push-list was undefined.  I had
to initiate calc first so maybe a 

: (require 'calc)

is required to ensure the functions you use are available?

Then, out of the three examples you give, only one (3^3) worked.  The
others give me:

--8<---------------cut here---------------start------------->8---
Debugger entered--Lisp error: (wrong-type-argument stringp (2 "Expected a number"))
  string-match("\\` *\\([0-9]+\\) *\\'" (2 "Expected a number"))
  math-read-number((2 "Expected a number"))
  (list (math-read-number (calc-eval line)))
  (calc-push-list (list (math-read-number ...)))
  (if (string= "'" (substring line 0 1)) (funcall (lookup-key calc-mode-map ...) nil) (calc-push-list (list ...)))
  (progn (if (string= "'" ...) (funcall ... nil) (calc-push-list ...)))
  (if (> (length line) 0) (progn (if ... ... ...)))
  (when (> (length line) 0) (if (string= "'" ...) (funcall ... nil) (calc-push-list ...)))

  mapcar((lambda (line) (when (> ... 0) (if ... ... ...))) ("  1" "  2" "  '+" ""))

Have I done something wrong?

I am particularly excited, once it works for me, to use this for
/inline/ babel executions!

Thanks,
eric
