I really like the hungry-delete minor mode that cc-mode provides, so I
would like to have it in other modes, specifically Python mode.
Right now, this does not seem to possible easily, because python-mode
does not inherit from cc-mode, correct?
I can do
(require 'cc-mode)
(global-set-key (kbd "C-<delete>") 'c-hungry-delete-forward)
(global-set-key (kbd "C-<backspace>") 'c-hungry-delete-backwards)
which enables the hungry-delete globally, but I would like to have some
more finer control over the behavior and set it up in a mode-hook, like
python-mode-hook.
Is there any reason why hungry-delete mode (or subword mode or
auto-newline mode for that matter) is so tightly coupled with cc-mode?
Would it be possible to decouple them and make the functionality
available to other modes as a minor mode instead of them being just
"minor-mode-like features" in cc-mode?

For DEL at least, you can
(global-set-key [?\^?] 'backward-delete-char-untabify)
and even control it via buffer-local settings of
backward-delete-char-untabify-method.

Because the CC-mode author wanted to provide the feature to all CC-mode
users and/or did not make the effort to try and submit this feature for
separate inclusion in Emacs.

Of course it's possible. As a matter of fact we do have subword-mode,
as well as electric-layout-mode.

I actually ran into this before, and ended up moving the necessary machinery
out of cc-mode into it's own mode. You can take a look at
https://github.com/nflath/hungry-delete
Thanks,

I didnt know about backward-delete-char-untabify-method. I will have a
look at that.

So no technical or historical reason.

It looks like subword-mode was created from cc-subword.el.It looks like
the hungry delete functions are pretty self contained and could be
factored out into a separate mode pretty easily. Maybe something to look
into for a future project.
Thanks,
Christoph
