Hi all,
I have a feature request (if what I want is not already possible, that is).
Could a source code block, which has the :session header argument, be
associated with its session as soon as C-' is pressed?
The background to this question is, that all ess support functionality
for R (r-autoyas, autocomplete-R, and ess-eldoc) need an associated R
session. They start to function only as soon as the first line of the
code block is evaluated, which associates the source buffer with its
session.
The autocomplete-R even fails to load without an associated R session
(byte-code: Language mode `R-mode' fails with: "Symbol nil may not be
buffer-local")
and this way cuts the connection to org, such that C-' becomes undefined.
Regards,
Andreas

This seems reasonable,
Do you know how ESS associates a code buffer with a session (i.e. is
there some buffer-local variable which holds the session name)?
With this information in hand it shouldn't be difficult to expand the
C-' behavior for R s.t. it automatically associates the resulting
Org-Src buffer with the proper R session.
Good idea. Best -- Eric

Hi Eric,
thanks for looking into this!
Unfortunately, I do not know the setup here. But I asked on the ess
mailing list and got an answer from Stephen Eglen:
"I think you want to set ess-local-process-name given by the :session
argument in the .org buffer when the temp buffer is opened by C-c '."
I hope that is the information you need.
Regards,
Andreas

I opened up a example.R buffer, evaluated some code, and a session named
"*R*" was created and the value of `ess-local-process-name' was set to
"R", so I've just pushed up a patch which will set the value of
`ess-local-process-name' to "something" if the value of the :session
header is "*something*", it will also start the session if none exists.
Please let me know if this give the desired result. If not, then could
you point me to an ESS feature which uses the associated session which I
could use locally to test?
Note also, that this patch adds a general facility through which any
language can prep an org edit src buffer through the definition of a
org-babel-edit-prep:lang function, which will be passed the full info
list for the code block. If there are any other languages which would
benefit from edit-buffer initialization it should now be a simple task
to implement such initialization.
Thanks -- Eric
