Org-babel init

Org-babel init

[Jordi Inglada]

Hi all,

I am having the same problem as this user here:

http://www.mail-archive.com/emacs-orgmode@gnu.org/msg17498.html

and the contrib/lisp directory is indeed in my load path.

I am using a git changeset cloned today (Org-mode version 6.34trans
(release_6.36.608.gc1ef)).

I have tried using "emacs -q" and then loading an .el file containing
only the following lines:

(setq load-path (cons "/home/inglada/local/src/org-mode/lisp" load-path))
(setq load-path (cons "/home/inglada/local/src/org-mode/contrib/lisp" load-path))

(require 'org-install)
(require 'org-babel-init)
(require 'org-babel-python)

and I get the same result.

Thank you very much for your help.

Jordi

I havent looked in detail but I recently had issues with it. Here is my
init.el. No idea if its even relevant to be honest, but babel works for
elisp files ;)

Re: Org-babel init

[Eric Schulte]

Hi Jordi,

With the latest Org-mode from Git, Org-babel is now part of Org-mode, so
you no longer need to add the contrib directory to your load path, or
require org-babel-init.  The following should work for you.

(setq load-path (cons "/home/inglada/local/src/org-mode/lisp" load-path))
(require 'org-install)
(require 'ob-python)

note that for a language-specific require, you now prefix the language
name with ob- rather than org-babel-

For more complete information on the new setup, see
http://eschulte.github.com/babel-dev/DONE-document-configuration-changes-for-Babel-integration.html

Cheers -- Eric

Hi Richard,

You could probably safely simplify your config to something more like
the following.

Re: Org-babel init

[Jordi Inglada]

Eric,

Thanks for the answer.

If I do that using "emacs -q", I get this message when loading the
configuration:

"Symbol's value as variable is void: org-babel-tangle-lang-exts"

An after that when trying to evaluate this block from the tutorial

#+begin_src python
import time
print("Hello, today's date is %s" % time.ctime())
print('Two plus two is')
return 2 + 2
#+end_src

I get this other message:

"org-babel-execute-src-block: No org-babel-execute function for python!"

If I put the configuration in my .emacs, the error I get is:

"org-babel-result-hash: Symbol's value as variable is void: org-babel-lob-one-liner-regexp"

I guess I missed something.

Thanks.

Jordi

Hi Jordi,

The attached simple-init.el file works for me with

  emacs -Q -l simple-init.el

Emacs started w/o error, and I was able to evaluate python code blocks
with no problem.

Please give it a try and let me know if it doesn't work -- Eric

(note you'll have to update the path to org/lisp)
