In ESS/Emacs, how can I get the R process buffer to scroll to the bottom after a C-c C-j or C-c C-r
Probably a bunch of ways to do it. In my .emacs.d I have
(setq comint-prompt-read-only t) (setq comint-scroll-to-bottom-on-input t) (setq comint-scroll-to-bottom-on-output t) (setq comint-move-point-for-output t)You might also be interested in this code, originally from Felipe Csaszar, which lets you do what you ask and a few other nice things besides.
Have a look at auto-scrolling in emacs doc. For my part:
customize-variable RET scroll-down-aggressively RET
scroll-down-aggressively set to 1 did the job.
DJJ's solution works perfectly for ESS and polymode in Spacemacs.
First, put (scroll-down-aggressively 1) within the defun dotspacemacs/user-config () section of the configuration file, e.g. ~/.spacemacs.
Then, evaluate the line using SPC , e r or restart configuration SPC f e d.
Emacs 27 complained about the above line because "Symbol's function definition is void" so I had to change it as follow to achieve the same result:
(setq scroll-down-aggressively 0.01)
