;;; Commentary:

;; This package is intended to emulate Nvim-R's object browser, for ESS.

;;; Code:

(defvar robj-buffer "*R object browser*"
  "Name of buffer for displaying R objects.")

(defun r-object-browser ()
  "Show an R object explorer."
  (interactive)
  (unless (and (string= "R" ess-dialect)
               ess-local-process-name)
    (error "Not in an R buffer with attached process"))
  (let ((proc ess-local-process-name))
    (pop-to-buffer (get-buffer-create robj-buffer))
    (setq ess-local-process-name proc)
    (r-object-browser-mode)))

(defun r-object-browser-mode ()
  "Run R object browser mode.")

(provide 'r-object-browser)
