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

[José L. Doménech]

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:

I added some clarification to the manual on that point. Thanks for
pointing out it was a confusing!

Hi Byung-Hee,

org-mode itself uses emacs lisp as the programming language for

However, if you are interested in learning Python and/or Ruby I highly 
recommend you look at the org-babel features: 
http://orgmode.org/worg/org-contrib/babel/ .
This allows you to mix up code blocks with your notes and links for an 
interactive "notebook" similar to Jupyter. (If you haven't tried 
Jupyter, you really should look at that too!)


I also recommend to take a look at John Kitchin's YouTube channel:

https://www.youtube.com/channel/UCQp2VLAOlvq142YN3JO3y8w

He uses extensively Emacs org-mode, Python and LaTeX.


Best

These blocks will appear as formatted code blocks in your output HTML or LaTeX. 
I use it as a lab notebook.



All the best,

In principal, it would be good to use cl-lib, but htmlize.el is an
external package that Org relies on.

I think htmlize is maintained here:

Re: [O] Ruby or Python or Something

[Roland Everaert]

I guess it depends if you need to access external resources or not (DB,
webservices) or if you need to do heavy computations, for exemple. If not
and if you know lisp well, then, I think, it is better to stick with it.

As a dev/sysadmin, I tend to use whatever language suites my needs when
writing documents or adding data to some TODO item with emacs and org-mode.
