E.g. if it is set to 1, the childframe is cleared 1 second after you moved the point to somewhere else (that doesn't have a doc to show). This doesn't apply to =eldoc-box-hover-at-point-mode=, in that mode the childframe is cleared as soon as point moves.

** Use with eglot
|
||||
As of writing this README, eglot doesn't have a public mode hook, use this hook:
|
||||
#+BEGIN_SRC emacs-lisp
|
||||
(add-hook 'eglot--managed-mode-hook #'eldoc-box-hover-mode t)
|
||||
#+END_SRC
|
||||
** Help at point hack
|
||||
If all you need is a "help at point" popup to be used with eglot, here is my hack:
|
||||
#+BEGIN_SRC emacs-lisp
|
||||
(defun moon-help-at-point ()
|
||||
(interactive)
|
||||
(when eglot--managed-mode
|
||||
(require 'eldoc-box)
|
||||
(let ((eldoc-box-position-function #'eldoc-box--default-at-point-position-function))
|
||||
(eldoc-box--display
|
||||
(eglot--dbind ((Hover) contents range)
|
||||
(jsonrpc-request (eglot--current-server-or-lose) :textDocument/hover
|
||||
(eglot--TextDocumentPositionParams))
|
||||
(when (seq-empty-p contents) (eglot--error "No hover info here"))
|
||||
(eglot--hover-info contents range))))
|
||||
(add-hook 'pre-command-hook #'eldoc-box-quit-frame t t)))
|
||||
#+END_SRC
|
