Full description

* Pop-up menus based on text properties

This is a library for computing context menus based on text
properties and overlays. The intended use is to have tools that
annotate source code and others that use these annotations, without
requiring a direct coupling between them, but maintaining

Major modes that wish to use this library should first define an
appropriate value for =prop-menu-item-functions=. Then, they should
bind =prop-menu-by-completing-read= to an appropriate
key. Optionally, a mouse pop-up can be added by binding
=prop-menu-show-menu= to a mouse event.

For example, the following value for =prop-menu-item-functions=
creates a popup menu that will describe faces that are set in either
text or overlay properties:
#+BEGIN_SRC elisp
  (setq-local prop-menu-item-functions
              (list (lambda (plist)
                      (let ((face (plist-get plist 'face)))
                        (when face
                          (list (list "Describe face" (lambda ()
                                                        (describe-face face)))))))))
Note that this setting requires lexical scope.
