r - Emacs auto-complete for ESS in tooltip instead of buffer -


i understand following resources:

...that should have access tooltips auto-complete in emacs when using ess r development. last link additionally specifies should work out of box latest ess, and:

from version 12.03 ess integrates out of box auto-complete package.

three sources ‘ac-source-r-args’, ‘ac-source-r-objects’ , ‘ac-source-r’ included in ess distribution. latest combines previous 2 , makes them play nicely together.

i know in general, emacs tooltips possible because appear correctly python jedi setup in emacs.

however, emacs auto-complete not work. instead, there buffer @ bottom:

instead of this, superimposed on working buffer:

enter image description here

and have following in init.el:

(require 'auto-complete) (setq ess-use-auto-complete t) (ess-toggle-underscore nil)

i have following versions of:

  ess                20131207.1141  installed  no description available.   ess-r-data-view    20130509.458   installed  data viewer gnu r   ess-r-object-popup 20130302.336   installed  popup description of r object   auto-complete      20140208.653   installed  auto completion gnu emacs

what missing?

update 1

here's init ess stuff. produces completions in buffer, not in tooltip, configuration options manual have been added. (i have tried permutations of commenting , not commenting of these):

(require 'auto-complete) (global-auto-complete-mode) (require 'auto-complete-config) (ac-config-default) (require 'ess-site) (setq ess-use-auto-complete t) (setq ac-auto-start 2) (setq ac-auto-show-menu 0.2) (ess-toggle-underscore nil)

update 2

similar question here, same solution suggested did not result in tooltips on setup. suggests me might platform issue? poster there on ubuntu 12.04 am---is possible solutions worked vitoshka, alex vorobiev, , iqbal ansari on different platform? guys using os x?

update 3

maybe other diagnostics:

ac-source-r variable defined in `ess-r-d.el'. value ((prefix . ess-ac-start)  (candidates . ess-ac-candidates)  (document . ess-ac-help))   documentation: combined ad-completion source r function arguments , r objects  ac-source-r-objects variable defined in `ess-r-d.el'. value ((prefix . ess-symbol-start)  (candidates . ess-ac-objects)  (document . ess-ac-help-object))   documentation: auto-completion source r objects  ac-source-r-args variable defined in `ess-r-d.el'. value ((prefix . ess-ac-start-args)  (candidates . ess-ac-args)  (document . ess-ac-help-arg))   documentation: auto-completion source r function arguments  [back]

where variables ess-ac[tab] only...

click <mouse-2> on completion select it. in buffer, type ret select completion near point.  possible completions are: ess-ac-r-argument-suffix ess-ac-sources

so maybe problem ess install lacking ess-ac-* things defined above, ess-ac-args, etc?

my auto-complete configuration has

(require 'auto-complete-config) (ac-config-default)

and after setting ess-use-auto-complete makes ess show popup menus.
