Orgmode + other modes for outlining and studying.

Orgmode + other modes for outlining and studying.

[Marcelo de Moraes Serpa]

[-- Attachment #1.1: Type: text/plain, Size: 740 bytes --]

Hello guys,

Orgmode files are great for studying, for example, code.

Everytime I need to study some unknown code, I create a new org file, put a
* Code headline, paste the code in there and start making notes below or in
the code (as comments). It is extremelly fast and efficient to do something
like that, things just flow.

What I'd like to know is if there's a way to have, for example, orgmode +
javascript-mode, so that I can get syntax-highlighting/coloring on the
pasted javascript code. I've tried with javascript mode, but since it is a
major mode, it just kills org and all its goodies, and I don't want that.

Is there a way to have two major modes at the same time, such as org +
js-mode?

Thanks in advance,

Marcelo Serpa.

yes, but it will be buggy, see

what about mmm mode? Anyone try it with org?

I tried to implement mmm-mode support for org-mode source code blocks
following the sample recipes provided along with the mmm-mode source.
These efforts were met with almost no success.

using this org-mode buffer http://gist.github.com/271820

and this mmm-mode activation code http://gist.github.com/271822

I was able to get a block of css code to fontify from within an org-mode
buffer-- for some unknown reason I was not able to highlight blocks of
ruby or emacs-lisp code.

I fear the "one major mode per buffer" assumption is deeply embedded in
Emacs and *any* such solution will probably end up being buggy.

Are you aware of Org-babel's SRC blocks?

#+BEGIN_SRC java
bla bla
#+END_SRC

And, to work on that source block, just hit C-c C-c when point is in the
block.

Best regards,
  Seb

Hi Seb and Marcelo,

Currently, java isn't on the list of Org-babel supported languages, so  
I don't know if Seb's solution will work out of the box.  Org-babel  
has a facility for adding new language support.  A java addition would  
be great.  Seb, if you have this working could you share your approach?

I agree with Seb that Org-babel is useful in the situation that  
Marcelo describes.  I use it this way myself with python.  Comments  
are distinguished from code very cleanly.  In effect, you end up with  
a literate program.

All the best,
Tom

Did not know that. Not using it myself.

Yes, you can easily add new languages. I did that for AWK:

--8<---------------cut here---------------start------------->8---
;; Org-babel needs to be told to recognize awk source code blocks and
;; how they should be tangled, which can be accomplished with the
;; following:
(org-babel-add-interpreter "awk")
(add-to-list 'org-babel-tangle-langs '("awk" "awk"))
--8<---------------cut here---------------end--------------->8---

I guess replacing awk by java would make it. Untested, though, as I don't use
it.

I guess this is the best thing to do, yes. Thanks for your comment (and
support), Thomas!

Best regards,
  Seb

The editing of source-code blocks is a feature of the Org-mode so it
will work regardless of whether or not a particular language (e.g. java)
is supported by Org-babel.

What would it take to add AWK to the list of supported languages, in  
addition to Seb's setup?

It is currently possible to run awk one-liners using a shell script
block, but I guess awk does straddle the line between command-line
command and full-fledged language.

It would be possible to add support for awk as a language by fleshing
out the org-babel-template.el [1] following the directions in that file
itself.  All of the *session* functions can be ignored (as I don't think
there is such a thing as an interactive awk session) which makes this
task relatively simple.  Another good guide could be org-babel-ditaa.el
[2] which is also a fairly simple language.
