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.
