How to split the popup "Buffer Menu" by major mode?

How to split the popup "Buffer Menu" by major mode?

[Lingyu Ma]

[-- Attachment #1: Type: text/plain, Size: 430 bytes --]


When press click the left button with ctrl key pressed (<C-down-mouse-1>), emacs will run the command "mouse-buffer-menu".

If I open a lot of buffers in different modes, the popup menu will generate several submenus as "Buffers 1", "Buffers 2", "Buffers 3" and so on.

Is there a way to make the popup menu split according to buffers' major modes? For example, "C++", "Java", "Org-mode"?

Thanks in advance!

No doubt someone else will be able to help you more, but take a look at option
`mouse-buffer-menu-mode-mult' (whose doc string is not very good, IMHO).
Setting it to 1 or 0 should apparently do what you want.

FWIW - `mouse-buffer-menu' also uses variable `mouse-buffer-menu-mode-groups'.
According to the (nearly incomprehensible) doc string for
`mouse-buffer-menu-mode-mult' you should not need to modify
`mouse-buffer-menu-mode-groups'.  But you might try doing so anyway just to see
what happens. ;-)  Apparently things are meant to be magic, which is too often
just another word for user-unfriendly. ;-)

Hi Drew,

I add (setq mouse-buffer-menu-mode-mult 1) into .emacs, and it works
perfectly.
(setq mouse-buffer-menu-mode-mult 0) works also.
The default value is 4.

Thanks!

regards,
Lingyu

When press click the left button with ctrl key pressed (<C-down-
mouse-1>), emacs will run the command "mouse-buffer-menu".

If I open a lot of buffers in different modes, the popup menu will
generate several submenus as "Buffers 1", "Buffers 2", "Buffers 3" and
so on.

Is there a way to make the popup menu split according to buffers'
major modes? For example, "C++", "Java", "Org-mode"?

Thanks in advance!

(setq mouse-buffer-menu-mode-mult 0)

Try this,
