** Use with eglot ** Use with eglot
As of writing this README, eglot doesn't have a public mode hook, use this hook: As of writing this README, eglot doesn't have a public mode hook, use this hook:
#+BEGIN_SRC emacs-lisp #+BEGIN_SRC emacs-lisp

** 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

(let ((eldoc-box-position-function #'eldoc-box--default-at-point-position-function))
