<<I'm adding ess-help to the addressees because apparently this needs to be
solved in ESS, not in R.>>
Thanks! So I guess you're suggesting something like
(add-hook 'comint-output-filter-functions
(lambda (s)
(save-restriction
(narrow-to-region comint-last-output-start
(+ -1 (process-mark (get-buffer-process (current-buffer)))))
;; stop one char before the end of the output region to
avoid
;; deleting the space after the R prompt
(delete-trailing-whitespace))))
I have almost succeeded in making this work right. But if it is called for
an output chunk which isn't the last one (with the prompt), it can suppress
spaces in the middle of the line. Test with
for (i in 1:1000) print("
")
for example. Any ideas? This is the sort of niggling little edge-case
complication which made me hope that someone had already solved the problem
in R or ESS....
