Evaluating code from ESS-R buffer causes inferior buffer to add an extra prompt symbol

[kaibagley]

Hey,

Minor issue, but as the title says sending code from an R buffer to the inferior ESS buffer results in two prompt symbols:

> > arg2 <- c(ntrt, b)

Relevant init.el:

(use-package ess
  :custom
  (ess-indent-with-fancy-comments nil)
  (ess-nuke-trailing-whitespace-p t)
  (ess-toggle-underscore nil)
  (ess-toggle-S-assign nil)
  (ess-disable-underscore-assign t)
  (ess-eval-visibly 'nowait)
  :config
  (add-hook 'inferior-ess-mode-hook
            #'(lambda ()
                (add-to-list 'mode-line-process '(:eval (nth ess--busy-count ess-busy-strings)))))
  (defun kb-run-air-on-r-save ()
    "Format .R files with Air on save."
    (when (string-match-p "\\.[rR]$" (or buffer-file-name ""))
      (shell-command (concat "air format \"" buffer-file-name "\""))
      (revert-buffer nil t t)))
  (add-hook 'after-save-hook 'kb-run-air-on-r-save))

Actually this seems related to an issue I've been having.

I can get two different outputs from the same code. If one is called from an R buffer, and one is called from the iESS buffer, this is an example:

> which(design$block == blk)
[1]  1  5  9 13 17 21
> > which(design$block == blk)
[1]  4  8 12 16 20 24

And the code from the R buffer has the double prompt. This is a pretty disruptive problem so I hope this is just a configuration thing, because I can't see anyone else complaining about this

Sorry, I can't replicate this with 24.01. Which version of ESS is this?

From, the .R file...
R> require(Rcpp)

From, the iESS[R] buffer ...
R> require(Rcpp)

Hmmm, it is inconsistent to reproduce. I'll close this for now until I can figure it out a bit more

Thanks
