hi, Eric,

this patch isn't mine, but rather Michael Gauland's; i just wondered
where it had gone.

cheers, Greg

Babel: User geiser for scheme interactions

* lisp/ob-scheme.el Major rewrite to support geiser

This patch uses geiser to execute scheme blocks.  Most features of babel
are tested and demonstrated in the attached org file.

Note that because ":results output" and ":var" blocks are wrapped before
being passed to scheme, "(define...)" will generate an error in such blocks.

  This block should return =64=:

  This block should return the string ="A B C D E"=:

  This block should return the list =(1 4 9 16 25)= (which org will display as a table).
  #+BEGIN_SRC scheme :results value :var z='(1 2 3 4 5) :wrap nil
  (map (lambda (x) (* x x)) z)
  #+END_SRC

* Tables
  :PROPERTIES:
  :wrap:     nil
  :session:  nil
  :END:
  Pass a table to scheme:
  #+NAME: data-table
  |       | A | B | C | D |  E |
  | Row 1 | 1 | 2 | 3 | 4 |  5 |
  | Row 2 | 6 | 7 | 8 | 9 | 10 |

  This block should show the table above:
  #+BEGIN_SRC scheme :scheme racket :results value :session :var x=data-table
  x
  #+END_SRC

  This block rerses the table left to right:
  #+BEGIN_SRC scheme :scheme racket :results value :session :var x=data-table
  (map reverse x)
  #+END_SRC

  This block will be passed to scheme with the column headers removed; the data
  and row labels will be reversed, but the column labels will not.
  #+BEGIN_SRC scheme :scheme guile :results value :session :var x=data-table :colnames t
  (map reverse x)
  #+END_SRC

  This block will be passed to scheme with the row headers removed; the data
  and column labels will be reversed, but the row labels will not.
  #+BEGIN_SRC scheme :scheme guile :results value :session :var x=data-table :rownames t
  (map reverse x)
  #+END_SRC

  This block will be passed to scheme with bothe the row and column headers
  removed; the data will be reversed, but the row and columns labels will not.
  #+BEGIN_SRC scheme :scheme guile :results value :session :var x=data-table :colnames nil :rownames t
  (map reverse x)
  #+END_SRC

  This block will adds a row of data; note that the column and row headers are lost:
  #+BEGIN_SRC scheme :scheme guile :results value :session :var t=data-table :colnames t :rownames t
    (let* ((row-1 (car t))
           (row-2 (cadr t))
           (total (map + row-1 row-2)))
    (append t (list total)))
  #+END_SRC

  This block adds a row of data, but handles the column and row headers in scheme:
  #+BEGIN_SRC scheme :scheme guile :results value :session :var t=data-table
    (let* ((col-labels (car t))
           (row-1 (cadr t))
           (row-2 (caddr t))
           (total (append
                   '(Total)
                   (map + (cdr row-1)  (cdr row-2)))))
        (append t (list total)))
  #+END_SRC
