I guess Vikas can speak for Vikas, but he was responding to my
observation of the same:
"... I'd like Org to pick up the fact that there's a :session
argument with a custom name and use that for C-RET in the edit buffer;
otherwise it generates the default *R* session there, but if you C-c
C-c the block later it puts it into the custom session name."
Here's an ECM:
#+begin_example
* heading
#+name: x
#+begin_src R :session r
x <- 1:10
#+end_src
#+name: y
#+begin_src R :session r
y <- x^2
#+end_src
#+end_example
So, say I start working on a document for the day and enter the
editing buffer with C-c ' on block x. I then C-RET from the edit
buffer, which evaluates x and starts a new R session, *R*. Now I'm
done and go on to block y, but don't need to edit. Maybe I just want
to update a plot or other result in the document, so I C-c C-c:
Error: object 'x' not found
This really, really common for my work. I define a setup block
somewhere in which I load libraries, read in thousands of lines of
sensor code, and process things (moving averages, summary stats, etc.)
and create my sort of "master object." From there I have sections of a
report that subset the data, plot various things, but typically have
them all set to :eval no by default. If I pick up work on a file, edit
my setup code block, but only interactively because I forget I need to
C-c C-c something first to kick off the custom session, the work was
sort of for naught as everything is in the wrong session.
In this example, I realize the error and go back to block x and C-c
C-c after failing on block y. At that point, when I go to a block
interactively to do C-RET again, I get this in the minibuffer.
Process to load into: {r | *R* | *new* }
Then I switch to *R* to quit() and end the spurious session.
Really, it was a comment about how Org behaves, not necessarily a bug.
That said, speaking for myself, I would never want a default session
in interactive mode when I've defined one in the code heading. I'd
love if Org could pick up on that setting, such that the first C-RET
of the day dropped into the session named by the block I'm editing. At
present, interactive mode appears to ignore this.
Hope that helps clarify,
John
