Tangling

Tangling

[Andrea Crotti]

So for my presentation I'm preparing a minimal emacs configuration which
will have
- org-mode/babel
- python mode
- yasnippet/auto complete 

And it will be everything here
http://github.com/AndreaCrotti/Org-mode-notes

I'm running
Org-mode version 6.34trans
on
GNU Emacs 23.1.50.1
(i386-apple-darwin9.8.0, NS apple-appkit-949.54) of 2009-09-16 on neutron.local

But I don't know why I'm not able to tangle anything and then load the
elisp code from an org-mode file.

--8<---------------cut here---------------start------------->8---
ELISP> (org-babel-load-file "/Users/andrea/Documents/pycon/miniconf.org")
*** Eval error ***  No buffer named miniconf.org
--8<---------------cut here---------------end--------------->8---

But the file is actually there, or like this
--8<---------------cut here---------------start------------->8---
ELISP> (org-babel-tangle "/Users/andrea/Documents/pycon/miniconf.org")
nil
--8<---------------cut here---------------end--------------->8---

And it doesn't export any source even if it looks something like this

--8<---------------cut here---------------start------------->8---
* Org mode
** Clock configuration
#+begin_src elisp :tangle yes
;; Clock configuration
(setq org-clock-persist t)
(org-clock-persistence-insinuate)
#+end_src
--8<---------------cut here---------------end--------------->8---

Any idea?

I think you meant

(org-babel-tangle-file "/Users/andrea/Documents/pycon/miniconf.org")

here

Although Org maps "elisp" to emacs-lisp-mode in org-src-lang-modes
(therefore C-c ' works), Org-babel currently does not recognise "elisp"
by default. Thanks for raising this, I think we need to make ourselves
more compatible with org-src-lang-modes.

So the short answer is: change "elisp" to "emacs-lisp".

The longer answer is, you could do

(org-babel-add-interpreter "elisp")
(add-to-list 'org-babel-tangle-langs '("elisp" "el"))

But you (we) 'll still be faced with the problem that org-babel-load-file
expects the blocks to be "emacs-lisp" blocks. org-babel-tangle-file, on
the other hand, will work.

Does that get things working?

Yes thanks a lot I was doing a stupid mistake, in other files I always
used emacs-lisp.
But if it will be aliased even better (I could do it myself but I've
made a snippet for it so I won't forget again)...

So now I have a strange behaviour, sometimes the file is loaded and
sometimes is not

This is the init file:

--8<---------------cut here---------------start------------->8---
(setq base "~/Documents/pycon/")
(setq conf (concat base "conf/"))

(add-to-list 'load-path (concat conf "org-mode/lisp"))
(add-to-list 'load-path (concat conf "org-mode/contrib/babel/lisp"))

(require 'org)
(require 'org-babel)
(require 'org-babel-tangle)

(org-babel-tangle-file (concat base "miniconf.org"))
--8<---------------cut here---------------end--------------->8---

The tangling works perfectly fine on my "real" emacs conf, but with the
testing configuration I get sometimes (don't understand why sometimes it
works this)

http://gist.github.com/362682

And is short

Debugger entered--Lisp error: (void-function -mode)

What is that supposed to mean? Just some stupid mistake again?
The file to load is 
http://github.com/AndreaCrotti/Org-mode-notes/blob/master/miniconf.org
but I guess that's correct because on one emacs it works perfectly fine

Hi Andrea,

I think that should be

(add-to-list 'load-path (concat conf "org-mode/lisp"))
(add-to-list 'load-path (concat conf "org-mode/contrib/lisp"))

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

(org-babel-tangle-file (concat base "miniconf.org"))

Great Dan thanks a lot, now it works perfectly!
So in case someone is interested can get the configuration I'm preparing here
http://github.com/AndreaCrotti/Org-mode-notes

Feel free to take what you need and modify as you wish, at the moment
it's working and should work everywhere (only my personal snippets are a
symlink so I guess it's not working outside my machine).
