- =eldoc-box-body= :: Default face used by childframe. I suggest to use a nice Sans Serif font such as Source Sans Pro, and a lighter or darker background.
- =eldoc-box-buffer-hook= :: Hook run after buffer for doc is setup.Run inside the new buffer.
- =eldoc-box-frame-hook= :: Hook run after doc frame is setup but just before it is made visible.Each function runs inside the child frame and receives the main frame as argument.
- =eldoc-box-only-multi-line= :: Set this to non-nil and eldoc-box only display multi-line message in childframe. One line messages are left in minibuffer.
- =eldoc-box-cleanup-interval= :: After this amount of seconds will eldoc-box attempt to cleanup the childframe. 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.
- =eldoc-box-self-insert-command-list= :: By default =eldoc-box-hover-at-point-mode= only keeps childframe display while you are typing (=self-insert-command=). But if you bind something else to your keys, eldoc-box can’t recognize it and will hide childframe while yu hit that key. Add your command to this list so eldoc-box won’t hide childframe when this command is called.
To keep eldoc from displaying documentation at point without enabling any minor mode above: =(add-to-list 'eglot-ignored-server-capabilites :hoverProvider)=.
Eldoc-box also provides a convenient command =eldoc-box-eglot-help-at-point=. Calling this command on a symbol displays a documentation childframe at point. No need to enable any minor mode for this.
