the problem for eldoc for me is that for some reason it gets pretty
confusing trying to implement lots of things all at once, at least
when emacs is already using it for something, or so.

here is my current jumble of code.  it does work.  and has comments
but idk if it is of any use.  or even understandable to anybody.

one other use for it that i have not gotten to in yeras but woulkd be
good is to have hovering over timestamps show you the number of days
from now to that timestamp.

so lots of uses for eldoc.

;; hover text
  (if (< emacs-major-version 24)
      (setq tooltip-use-echo-area t)
    (tooltip-mode -1)))

(unless (version< emacs-version "25")
  ;; i find this annoying in at least elisp, and prefer my
  ;; function enabled in elisp, which does interesting things for
  ;; org-link-minor-mode.  emacs 25 enables this by default.  it
  ;; might be itneresting to see where eldoc is useful.
  (global-eldoc-mode -1))
;; make pointer emit help-echo
;;   over org links
;; (setq eldoc-idle-delay 8.0)
;; (setq eldoc-idle-delay 0.0)
;; (add-hook 'prog-mode-hook 'eldoc-mode)
;; [[http://google.com][test]]
;; fixme why does this not work in either org or elisp?
;;   because there is no help-echo
;;   fixme add help-echo
;; [2017-01-16 Mon 12:48]
;; fixme why does this work on links in elisp without this hook?
;; (add-hook 'prog-mode-hook 'alpha-eldoc-help-echo-mode)
;; (add-hook 'org-link-minor-mode-hook 'alpha-eldoc-help-echo-mode)
(add-hook 'org-mode-hook 'alpha-eldoc-help-echo-mode)
;; in elisp we might want both link eldoc and elisp eldoc
;;   we also want org ts eldoc

  "Eldoc thingy for help-echo text properties.
