Enhance Org babel scheme

Hello, I have modified 'ob-scheme.el' to be able to return org tables.

This is a quick patch. I hope you find it useful buut I could modify,
document or write test for it if necesary.

I have already assigned the copyright for Emacs to the FSF.


Enhance the scheme babel block output.

Allow scheme code blocks to return a table.

* lisp/ob-scheme.el (org-babel-scheme-null-to): New custom option that
  allows to use a empty list to format the table output, initially assigned
  to 'hlines.
  (org-babel-scheme-table-or-string): New helper function to convert the
  return value from the block as a table or a string.
  (org-babel-execute-src-block): Changed to allow the return of a table for
  the output.

[PATCH] An amended to the enhance Org babel for scheme blocks

["José L. Doménech"]

[-- Attachment #1: Type: text/plain, Size: 916 bytes --]

Hello again, I have added a :prologue param to the scheme blocks of babel.
This multiple option prepends all the values in the generated code of the
block.

This patch also includes the previous one that enabled returning a table
when evaluating a scheme block.

A changelog:

Enhance the babel block for scheme.

Allows scheme code blocks to return a table and add a :prologue param
to the scheme blocks. All :prologue params are prepended to the
body of code.

* lisp/ob-scheme.el (org-babel-scheme-null-to): New custom option that
  allows to use a empty list to format the table output, initially
  assigned to 'hlines.
  (org-babel-scheme-table-or-string): New helper function to convert
  the return value from the block as a table or a string.
  (org-babel-execute-src-block): Changed to allow the return of a
  table for the output.
  (org-babel-expand-body:scheme) Add :prologue param support.

The patch:

The parenthesis needs to be moved at the end of the line above.

Would you mind also providing an ORG-NEWS entry for that change?

No, but I don't know what is the preferred format for the entries. So
instead of a patch i send the complete entries.
Also I have not explain why I added the :prologue header. I think it is
general enough to be used in more creative ways than mine.

** New Features
*** Babel
***** Scheme: new variable: ~org-babel-scheme-null-to~

 This new custom option allows to use a empty list or null symbol to
 format the table output, initially assigned to 'hlines.

***** Scheme: new function: ~org-babel-scheme-table-or-string~
 
 New helper function to convert the return value from the scheme block
 to a table or a string.

***** Scheme: new header ~:prologue~

 A new block code header has been created for Org Babel that enables
 developers to prepend code to the scheme block being processed.

 Multiple =:prologue= headers can be added each of them using a string
 with the content to be added.

 The scheme blocks are prepared by surronding the code in the block
 with a let form. The content of the =:prologue= headers are prepended
 before this let form.

The Changelog entry:

Allows scheme code blocks to return a table and add a :prologue param
to the scheme blocks. All :prologue params are prepended to the
body of code.

* lisp/ob-scheme.el (org-babel-scheme-null-to): New custom option that
  allows to use a empty list or null symbol to format the table
  output, initially assigned to 'hlines.
  (org-babel-scheme-table-or-string): New helper function to convert
  the return value from the block to a table or a string.
  (org-babel-execute-src-block): Changed to allow the return of a
  table for the output.
  (org-babel-expand-body:scheme) Add :prologue param support.

A improved Changelog entry:

Allows scheme code blocks to return a table and add a :prologue param
to the scheme blocks. All :prologue params are prepended to the
body of code.

* lisp/ob-scheme.el (org-babel-scheme-null-to): New custom option that
  allows to use a empty list or null symbol to format the table
  output, initially assigned to 'hlines.
  (org-babel-scheme-table-or-string): New helper function to convert
  the return value from the block to a table or a string.

OK.

I think this can be kept as an internal function, and named
`org-babel-scheme--table-or-string'.

is sufficient in this case.

Likewise: "New function."

> +(defun org-babel-scheme-table-or-string (results)

Per above, I suggest to name it `org-babel-scheme--table-or-string' and
update the code accordingly.

I made the changes suggested above and added a "TINYCHANGE" cookie at
the end of the commit message since I don't know I you signed the FSF
papers already. I you haven't, please consider doing it.

Thank you!

Thanks for the corrections.

I had already completed the assignment to the FSF for the Emacs proyect (about 17 Nov 2016).
