[babel] noweb for :sessions?

[babel] noweb for :sessions?

Aloha all,

Is it possible to define frequently used code snippets in a generic  
way so they can be used in different sessions?

Something like this is what I have in mind:

#+srcname: r-connect
#+begin_src R :exports none :session any
library(rMySQL)
con <- dbConnect(MySQL(), user="user_name", password="password",
                      dbname="db_name", host="host_name")
#+end_src

#+srcname: r-query
#+begin_src R :session session-1
# <<r-connect>>
res <- dbGetQuery(con, "select * from table_name where 1")
#+end_src

Hi Tom,

That is an interesting proposal, and surprisingly simple to implement.
Please pull the latest version of Org-mode, and you will find that there
is now a :noweb header argument available for source-code blocks which
has the effect of expanding noweb references before source-block
evaluation (as you suggested below).  So for example the following
works.

--8<---------------cut here---------------start------------->8---
#+srcname: noweb-example
#+begin_src ruby 
  a = 28
#+end_src

#+begin_src ruby :noweb
  # <<noweb-example>>
  a + 4
#+end_src

#+resname:
: 32
--8<---------------cut here---------------end--------------->8---

Does this satisfy the behavior you were suggesting?

Thanks for the idea! -- Eric

Hi Eric,

Yes, I think that's it.  I appreciate your help.  org-babel has me  
feeling like a kid at Christmas.
