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.
