Dan Davison and I (Eric Schulte) are happy to announce that Org-babel
has now been released as a contributed package in Org-mode with
corresponding documentation on worg [1].
Org-babel provides the following functionality:
- Source-code execution and control of output in org buffers
- currently supported languages [2]:
- emacs-lisp
- shell scripts
- R
- ruby
- python
- SQL
- gnuplot
- dot
- ditaa
- asymptote
- Haskell
- OCaml
- css
- sass
- results of code execution can be [3]:
- passed to other source-code blocks
- inserted into Org buffer as Org-mode table
- inserted into Org buffer as escaped text
- inserted into Org buffer as raw Org-mode text
- dropped to a file and linked to from Org-mode buffer (e.g. ditaa)
- ignored
- Meta-programming language for org mode: each source-code block is
treated as a function which can accept arguments in the form of:
- entire org-mode tables
- output of other source-code blocks
- raw text
- values of cells in Org-mode tables using the Org spreadsheet
functionality
- Spreadsheet enhancement: source-code blocks can be called from
spreadsheet functions within tables
- Community maintained library of useful code blocks [4]
- reproducible research [5]
- literate programming with org-mode [6]
- Org-babel has special support for embedding your emacs
initialization in literate Org-mode files [7]
To activate Org-babel simply grab the latest version of Org-mode and add
the following to your Emacs init (more complete instructions at [8]).
(require 'org-babel-init)
Thanks -- Eric

Dan and Eric,
Just reading the documentation one can get excited by the possibilities it
brings to org-mode.
Thank you for this great contribution.
I have one question, as mentioned in the document on can pass a table to the
code block. Is possible to send a as a parameter a dynamic clock table?.
For example to create a pie-chart of the clock-table data using R?

Hi Miguel,
This feature is currently not implemented, however I will take a look at
including it. For such a feature to work you would have to add a name
to your dynamic clock table, something like...
#+BEGIN: clocktable :maxlevel 2 :block today :scope tree1 :link t :name todays-clock
#+END: clocktable
I'll let you know if I get this working. -- Eric

Hi Miguel,
It seems I spoke too soon, It looks like the current version of
Org-babel will support dynamic clock tables if they are structured as
the following with a #+tblname: line preceding the block.
--8<---------------cut here---------------start------------->8---
#+TBLNAME: todays-clock
#+BEGIN: clocktable :maxlevel 2 :block today :scope tree1 :link t
Clock summary at [2009-09-15 Tue 08:51], for Tuesday, September 15, 2009.
| L | Headline | Time | |
|---+--------------+--------+------|
| | *Total time* | *1:10* | |
|---+--------------+--------+------|
| 1 | top | 1:10 | |
| 2 | show all | | 1:00 |
| 2 | later | | 0:10 |
#+END: clocktable
#+begin_src emacs-lisp :var data=todays-clock
(length (car data))
#+end_src
#+resname:
: 4
#+begin_src emacs-lisp :var data=todays-clock
(length data)
#+end_src
#+resname:
: 4
--8<---------------cut here---------------end--------------->8---
Unfortunately I don't know much about R, so converting the times to
something easily graphed in a pie chart may be a little bit more
difficult.
Best -- Eric

What else should I say - THIS IS GREAT NEWS!!
I wonder how complicated it would be to add more languages. Especially
PHP, JavaScript (e.g. per rhino) and Perl.
Is there some documentation or advice on the net in that concern? I'd
like to add a language I understand besides Bash... :)
Hmmm - maybe `org-babel-sh.el' is a good starting point.
* Some thoughts
I actually wonder, if all those interpreted languages are different at
all. Why not add an generic call to interpreters. Executing Shell
scripts or Perl, Php, JavaScript... makes no big difference here. On
Linux at least, they all work with either shebang or called with OPTION
FILENAME.
To execute a temporary file without shebang, all interpreters take a
filename:
rhino -f FILE # -f is optional
php -f FILE # -f is optional
perl FILE
Or execute code directly (which is useless for us, since we would need
to quote the code correctly...):
rhino -e CODE...
perl -e CODE...
php -r CODE...
So how about:
#+srcname: generic-circumference(a)
#+begin_src javascript :interpreter rhino -f
print ( "Write me to temp file and call `rhino -f TMPFILE'" )
java.lang.System.out.println ( 2 * a * java.lang.Math.PI )
#+end_src
This way, a source block written on my Linux-System would execute on her
MAC and his Windows machine without change (provided the interpreter is
installed and in $PATH... `org-program-exists' ... to use interpreters
without having them in $PATH, a customizable map could be used).
BTW: I just discovered rhino - looks interesting, seems you can
(de-)serialize Java(Script) objects... and thus keep track of things
between sessions ;) start programs, call Java Methods... See
https://developer.mozilla.org/en/Rhino_Shell
Best wishes,
Sebastian

Yes, I must admit the current set of implemented language is very
specific to Dan and my personal needs. I really hope that other people
add the languages they need/use, and I tried to design the structure of
org-babel to make the addition of new languages as painless as possible.

Yes, currently the best way to get a feel for how to add languages would
be to start with an existing language file (I'd suggest
org-babel-python.el or org-babel-ruby.el, or for simpler less
comprehensive language support look at org-babel-ditaa or
org-babel-haskell) and make changes from there. I agree that a brief
tutorial for adding language support would be helpful.
Basically Org-babel expects any new language file to define two
functions...
- org-babel-execute:lang-name (body params) :: which executes the code
in body according to the header arguments in params, and
- org-babel-prep-session:ruby (session params) :: which starts an
interactive session in session setting any variables from params

There are two key language specific features which keep us from treating
all interpreted languages identically.
1) Org-babel collects the last value of a source-code block to be
returned (see [1]) and this value needs to be collected and
potentially converted into elisp in a language specific manner
2) Org-babel has support for evaluation in a session allowing
persistence of state between different blocks which use the same
session. I now notice that the :session header argument is not
currently documented on the Worg page. I'll try to add this
documentation soon. The sessions are handled through Emacs comint
buffers which are very language specific.

I agree that it would be possible to implement a much more general
code-evaluation mechanism based on execution of temporary files, but we
would lose the nice features mentioned above.

Under the current setup, all source-code blocks should be executable on
*any* system which supports the required language and Emacs modes
mentioned in the commented elisp block at [2]

Was having a similar idea, as I language I'd love to use with this is
my current fave clojure:
http://clojure.org/
It's a language based on the JVM and consequently being able to pass
in command line options to the interpreter is important... I'd
imagine most of the time the source blocks within a single file would
share the vast majority of environment settings too (for example
setting the JVM's class path) so being able to specify these values to
pass to the interpreter, once at the top of the file would be really
nice.

A skeleton maybe?
And just a few comments describing the I/O of the basic functions
(and/or the global vars/containers that take the results).

Ahhh, I now comprehend. You're library makes all kinds of source blocks
work together as a whole. Great! I now understand your intention! Make
that old joke become true: "Emacs is a great OS, it's just missing a
good editor" :-D

Seriously: There's not that much code to write in the language
files. The features seem more than worth it. I just had little snippets
in mind... hrm, sorry.

OK - not _really_ RTFM :-D
I remember I stared at those sections last night - seems I was half

Good idea, I'm attaching an org-babel-template.el file which tries to be
just that. I'd be interested to hear how it works for you, or if you
want to make any changes. Once there is a good version maybe it would
be a good thing to either add to the babel/lisp/langs directory, or at
least to post on Worg.

heh, I hadn't thought of it that way, but yea, the idea is to allow
different languages to interact all using emacs-lisp as the
lower-common-denominator.

This should be easily implemented using a new header argument (languages
are free to define new header arguments as they see fit). For an
example of a language passing command line options through header
arguments, see the org-babel-ditaa.el file which defines a :cmdline
header argument allowing arguments to be passed to the ditaa command as
in the example below where the -r and -S options are passed to the ditaa
command.
--8<---------------cut here---------------start------------->8---
#+begin_src ditaa :file blue.png :cmdline -r -S
+---------+

Ahhh - now that I get simple output from PHP...
simple already worked for my, by taking the org-babel-python.el,
replacing org-babel-python-evaluate by org-babel-sh-evaluate and replace
all `python' and `sh' by `php'.
(OK - and wrap the `full-body' into `<?php ' and ' ?>').
But then I screwed it up by replacing the modified org-babel-sh-evaluate
by the org-babel-python-evaluate function again - now I don't get the
results out... but I'm on the track.
OK - I'll try the template. I need to understand the whole thing anyway
:)

I addressed the "passing command line" portion of your comment earlier
but neglected the "setting file-wide header arguments" portion.
RE: "setting file-wide header arguments"
it is now possible to set header arguments for subtrees of a file using
properties, for example the following will have :results silent set for
all of it's code blocks.
* silent
:PROPERTIES:
:results: silent
:END:
I agree file-wide settings would be useful, but they are not yet
implemented.

Eric et al.,
any chance of creating a jython interface? Or has anybody else done
this already?
I've tried creating one from your org-babel-python.el file by changing
all occurrences of python to jython (bar one: the run-python command
as that actually does run jython automatically, much to my surprise!).
That works for single shot executions. It does not work for sessions
and I really don't know where to start looking... Any pointers or
suggestions more than welcome, of course.
What I've done may work for (un?)-tangled code but haven't tried yet.
Thanks,
eric

Hi Eric,
Would you like to put your jython work so far in a public git branch,
for example (pending responses to my excellent suggestion the other
day...)
http://repo.or.cz/w/org-mode/babel.git [normal webpage; not a git url]
That way we can all have a go at it when time permits. If you email me
offline I can send you the admin password to give yourself push
permission.

That's awesome news! Thank you for this great contribution. Now I can use my
beloved ruby to write view-extensions to my org PIM :D (even though I'm very
interested in learning elisp, but this makes things much more practical and
powerful!).
