I'm preparing a presentation and I'm getting using tangle to show code /and/
produce working code examples -- this is really cool.
It is possible to define a "template" and pass code blocks to it?
For example: (Using pseudo-org-babel-code for brevity)
#+template
header code
<<code_that_is_passed_to_me>>
footer code
#+example1 :render #+template with 1111111
1111111111
#+example2 :render #+template with 222222
222222222
The tangled output would be:
header code
11111111111
footer code
header code
2222222222
footer code
I'm already able to use org-babel like below, but I have to
put a <<footer>> and a <<header>> in each code block.
Here's my existing setup:
#+header
header code
#+footer
footer code
#+example1
<<header>> <-- I have to specify these <<header>> and <<footer>> in
each code block
11111111111
<<footer>>
#+example2
<<header>>
2222222222
<<footer>>
Thanks again for org-babel -- I'll post my presentation when I get it done.

Hi Nathan,
The easiest way I can think of to accomplish templates would be through
some abuse of code block evaluation. Maybe something like the following
would work...
** tangle templates
#+source: template-heading
#+begin_src emacs-lisp
some stuff here
#+end_src
#+source: template-footing
#+begin_src emacs-lisp
some other stuff here
#+end_src
#+source: template
#+begin_src sh :results output :noweb yes :var body="body stuff"
heading=$(cat<<EOF
<<template-heading>>
EOF
)
footing=$(cat<<EOF
<<template-footing>>
EOF
)
echo $heading
echo "$body"
echo $footing
#+end_src
#+call: template[:noweb yes](body="something new")
#+results: template[:noweb yes](body="something new")
: some stuff here
: something new
: some other stuff here
I hope this makes sense, and isn't too gross looking, for a really clean
implementation the template function could be located in a different org
file using the library of babel.
Note, that this relies upon an improvement to variable escaping that I
just pushed up to the latest version in git.
Best -- Eric
