Different listing styles for same babel language?

Different listing styles for same babel language?

[Michael Gauland]

My org documents include lots of source code blocks, in a variety of
languages. I use the listings package to give each language a
distinctive look.

Lately, my work has involved using shell commands on different machines,
as different users. I'd like to give each shell environment (e.g., local
user, normal user on remote host, root on remote host) a different look.
At the moment, I'm doing this by specifying different shells (bash,
dash, sh) for each. This works, especially since I'm not executing the
commands from emacs, so it doesn't matter which shell I specify.

Is there a better way to do this? 

Would anyone else find it useful? I'm happy to  work on the code, if I'm
not the only one who'd use it.

See

 	(info "(org) Advanced configuration")

and scroll down to "Extending an existing back-end" where you will find 
a template for modifying the output of a src-block.

Assuming you derive your exporter from the latex backend, you want to have 
something like

#+ATTR_LATEX: :lstyle basic
#+BEGIN_SRC shell
   echo "Hello World"
#+END_SRC

in your *.org file and use

(org-export-read-attribute :attr_latex src-block :lstyle)

to grab the "basic" or whatever in setting up the transcoded result.

HTH,

I've found that #+ATTR_LATEX: :options language=.... does exactly what I
was looking for. The attached example may be useful to others.

I don't know how to accomplish this, but I'm guessing that, if you wrote
some code to change the style of individual code blocks, lots of people
would find that useful.  :)
