In a home-brewn language mode, I use the eldoc facilties.

--8<---------------cut here---------------start------------->8---
(defun tg-documentation-function ()
  (message "Called!")
  (let ((thing (thing-at-point 'sexp)))
    (if (string= thing tg--last-thing)
        tg--last-doc
      (setq tg--last-thing thing)
      (let ((eid (tg-edge-p))
            (vid (tg-vertex-p)))
        (cond
         ((tg-incidence-list-p)
          (tg-eldoc-incidence))
         (eid
          (tg-eldoc-vertex-or-edge-at-point 'EdgeClass))
         (vid
          (tg-eldoc-vertex-or-edge-at-point 'VertexClass))
         (t
          (setq tg--last-doc nil))))
      tg--last-doc)))

(defun tg-eldoc-init ()
  (set (make-local-variable 'eldoc-documentation-function)
       'tg-documentation-function)
  (add-hook 'after-save-hook
            'tg-init-schema nil t)
  (tg-init-schema))
--8<---------------cut here---------------end--------------->8---

This worked very nice some time ago, but now my documentation function
is only called if point changes the line, but not on point movement on
the current line.

An idea: did you check that `eldoc-message-commands' contains the
commands after which you expect Eldoc to show the info? Maybe the recent
bidi changes could affect this (i.e., some commands were renamed IIRC)?

Indee, you are totally right.  I use the arrow keys quite often for
navigating in the current line, and nowadays they are not equivalent to
C-g and C-b anymore.  The former is left/right-char, while the latter is
forward/backward-char.

So the left/right-commands should be added to `eldoc-message-commands',
too.

Bye,
Tassilo
