Hi
I would like to use :prologue and :epilogue to enclose the code block
in a local({}) block, i.e.
* test
#+begin_src R :prologue local({ :epilogue })
qwerty <- "test"
#+end_src
But the problem seems to be the unbalanced brackets, and everything is
passed on as the prologue, as I get the error:
Error: unexpected ':' in:
"{
local({ :"
Execution halted
Can I somehow use unbalanced brackets, or is this a missing option in
epilogue and prologue?
Cheers,
Rainer

I tried wrapping the prologue and epilogue values in quotes so that they
would be interpreted as strings, and I no longer see the problem you
describe and it works in a session, but I get a different R issues
outside of a session.

Agreed -
* test
#+begin_src R :results output :prologue "local({" :epilogue "})" :session
cat("Test")
#+end_src
#+RESULTS:
no :session nothing happens
using :session the execution does not complete because the :epilogue is not appended.
* test 2
#+begin_src R :results output :prologue "cat(1, '###\n')" :epilogue "cat(2, '###\n')" :session
cat("Test\n")
#+end_src
#+RESULTS:
: 1 ###
: Test
works under :session and without
but
* test 2
#+begin_src R :results output :prologue "{cat(1, 2 )" :epilogue "cat(2, 3)}" :session
cat("Test\n")
#+end_src
works only without :session as R is waiting for the "}" which is in the :epilogue but which is not added.

Rainer

The problem here is when `org-babel-balanced-split' parses the following
string.
":results output :prologue \"local({\" :epilogue \"})\" :session"
It isn't smart enough to *not* balance the ({}) parens because of the
enclosing quotes. Unfortunately I don't have time to address this right
now. A hacky work around would be the following...
#+headers: :epilogue "})"
#+headers: :prologue "local({"
#+begin_src R :results output :session
cat("Test")
#+end_src

Thanks - that looks fine to me for the moment. I whould use these
#+headers: much more often - they clean up the #+begin_src line and IU
actually like it.
