Here is the docstring from ESS's inferior-S-prompt:
inferior-S-prompt is a variable defined in `ess-custom.el'.
Its value is "[]a-zA-Z0-9.[]*\\([>+.] \\)*> "
Documentation:
Regexp used in S and R inferior and transcript buffers for prompt
navigation.
Customise it to make `comint-previous-prompt' quiqly navigate to
interesting portions of the buffer.
You can customize this variable.
----
Note that there is a space *required* after the [>+.], but the hard coded
regex in `org-babel-R-evaluate-session' lets the space be optional.
I am guessing the a-zA-Z stuff is there to strip 'Browse[1]> ' prompts and
such, which probably isn't an issue for babel.
Just before the defcustom for inferior-S-prompt, I see this comment
in ess-custom.el:
;; need to recognise + + + > > >
;; and "+ . + " in tracebug prompt
Ha! The '.' seems to be for ess-tracebug. I am guessing that nobody will
need to output tracebug sessions from babel. So maybe it is safe to delete
the "." after all - or at least require the space after it.
Maybe the regex should be put in a defcustom.
p.s. There is also `inferior-ess-prompt' which on my system is the same as
inferior-S-prompt (in an R buffer - its buffer local)
HTH,
Chuck
