Subject: Re: List possible completions in pop-up menu and choose from it.
Date: Sat, 20 Aug 2005 07:52:50 +0000
Thank you for your help.
Now I add following code to my site-start.el. When I press [M-up],
the menu
appears at point, with possible completions inside. It looks good.
However, after I select one item inside with mouse or keyboard, the
selection
isn't inserted into the buffer. Have I done something wrong?
(defun my-dabbrev-completion ()
"*Just like `dabbrev-completion', but display a popup menu."
(interactive)
(save-window-excursion ; suppress *Completions*
buffer
(dabbrev-completion))
(let ((menu (make-sparse-keymap "dabbrev-completion"))
(completions (let ((symbols '()))
(mapatoms (lambda (sym)
(setq symbols (cons sym
symbols)))
dabbrev--last-obarray)
(sort symbols 'string-lessp))))
(mapc (lambda (completion)
(define-key menu (vector completion)
`(,(symbol-name completion) .
(lambda ()
(interactive)
(insert ,(symbol-name completion))))))
(nreverse completions))
(autoload 'senator-completion-menu-point-as-event "senator" ""
t)
(x-popup-menu (senator-completion-menu-point-as-event)
menu));;pop-up at point
)
(global-set-key [M-up] 'my-dabbrev-completion)

dabbrev-completion stores its results in dabbrev--last-obarray,
which is
a data structure suitable for the completion functions. You can
read
about obarrays in the "Creating [and Interning] Symbols
==============================" node of the
Emacs Lisp manual.
Converting that to a menu keymap was too interesting for me to pass
up:
(let ((menu (make-sparse-keymap "dabbrev-completion"))
(completions (let ((symbols '()))
(mapatoms (lambda (sym)
(setq symbols (cons sym
symbols)))
dabbrev--last-obarray)
(sort symbols 'string-lessp))))
(mapc (lambda (completion)
(define-key menu (vector completion)
`(,(symbol-name completion) .
(lambda ()
(interactive)
(insert ,(symbol-name completion))))))
(nreverse completions))
(x-popup-menu t menu))
You can create your own command that you could bind to a key, mouse
click, or menu item by wrapping that in something like:
(defun dabbrev-mouse-completion (event)
"*Just like `dabbrev-completion', but display a popup menu."
(interactive "*e")
(save-window-excursion ; suppress *Completions* buffer
(dabbrev-mouse-completion))
...
)
And then replace the t POSITION argument to x-popup-menu with
event.
