Pop a posframe (just a frame) at point

What is posframe?

Posframe can pop up a frame at point, this posframe is a child-frame connected to its root window’s buffer.

The main advantages are:

1. It is fast enough for daily usage :-)
2. It works well with CJK languages.

NOTE:

1. For MacOS users, posframe needs Emacs version >= 26.0.91
2. GNOME users with GTK3 builds need Emacs 27 or later. See variable `posframe-gtk-resize-child-frames’ which auto-detects this configuration.

   More details:

   1. Fix some problems with moving and resizing child frames
   2. Emacs’s set-frame-size can not work well with gnome-shell?

Installation

(require 'posframe)

Usage

Create a posframe

Simple way

(when (posframe-workable-p)
  (posframe-show " *my-posframe-buffer*"
                 :string "This is a test"
                 :position (point)))

Advanced way

(defvar my-posframe-buffer " *my-posframe-buffer*")

(with-current-buffer (get-buffer-create my-posframe-buffer)
  (erase-buffer)
  (insert "Hello world"))

(when (posframe-workable-p)
  (posframe-show my-posframe-buffer
                 :position (point)))

Arguments

C-h f posframe-show

Hide a posframe

(posframe-hide " *my-posframe-buffer*")

Hide all posframes

M-x posframe-hide-all

Delete a posframe

1. Delete posframe and its buffer

   (posframe-delete " *my-posframe-buffer*")
       

2. Only delete the frame

   (posframe-delete-frame " *my-posframe-buffer*")
       

Delete all posframes

M-x posframe-delete-all

Note: this command will delete all posframe buffers. You probably shouldn’t use it if you are sharing a buffer between posframe and other packages.

posframe-arghandler

posframe-arghandler feature has been removed from posframe-1.1, user can use advice feature instead.

Default setting will work well in most case, but for EXWM user, suggest use the below config.
