;;
;; The whole point of this file is to enable debugging from a vanilla
;; environment. It probably isn't needed too much right now.
;;; Code:
(defun ess-add-path (path &rest options)
"Add PATH to `load-path' if it exists under `default-load-path'
directories and it does not exist in `load-path'.
You can use following PATH styles:
load-path relative: \"PATH/\"
(it is searched from `default-load-path')
home directory relative: \"~/PATH/\" \"~USER/PATH/\"
absolute path: \"/HOO/BAR/BAZ/\"
You can specify following OPTIONS:
'all-paths search from `load-path'
instead of `default-load-path'
'append add PATH to the last of `load-path'.
For ESS, ONLY use load-path, since Emacs doesn't have
default-load-path."
(let ((rest load-path)
p)
(if (and (catch 'tag
(while rest
(setq p (expand-file-name path (car rest)))
(if (file-directory-p p)
(throw 'tag p))
(setq rest (cdr rest))))
(not (member p load-path)))
(setq load-path
