Hi Rick, I believe this should be possible when using :session by altering the code that processes the output from the comint buffer. I had a quick attempt at hacking that and failed, as Eric's code in that area is quite sophisticated for me. (I still don't get how to debug macros.) So over to Eric. Note that when not using :session, this effect may still be possible on a language-by-language basis. For example, with R we can control this with arguments to the R executable: ~> echo '4+4' | R --vanilla > 4+4 [1] 8 > ~> echo '4+4' | R --vanilla --slave [1] 8 ~> and so a simple change to org-babel-R.el could introduce user control over this when using external process evaluation (a.o.t. session). I don't know whether ruby has something similar. For shell I'm also not sure. There's bash -x, but that's not quite the same. So perhaps we could introduce variables called something like org-babel-ruby-args and org-babel-R-args so that the user can specify these command line args to external interpreters. Dan
