Re: Org-babel init

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
