Using current style in C?

Using current style in C?

[Doug Lewan]

Once upon a time, I'll swear I read somewhere about being able to configure C-mode to "use the current style", but now I can't find it. I'd like to use such a feature.

That is, upon finding a file, I'd like emacs to examine it and use its indentation style while editing it. 

Does such a feature really exist? (I have been known to make stuff up.) A quick scan of the emacs Wiki didn't reveal anything to me.

Thanks.

Check c-guess (in cc-guess.el).

Stefan,

Thank you. 

c-guess looks exactly like what I was thinking about. I won't have any more time today to look at it, but tomorrow morning I will give it a try!

	Thanks, that could be very useful. However, I just tried adding the
following to my c-mode-hook to configure the style automatically
when I open a file:


(setq c-guess-guessed-basic-offset nil)
(setq c-guess-guessed-offsets-alist nil)
(c-guess-no-install)
(if c-guess-guessed-basic-offset
    (setq c-basic-offset c-guess-guessed-basic-offset))
(if c-guess-guessed-offsets-alist
    (setq c-offsets-alist c-guess-guessed-offsets-alist))


	For some reason, this is horribly slow (takes several minutes to
complete). When I remove those lines and launch c-guess-no-install
interactively with M-x, then it is almost instantaneous (less than
one second). Anybody knows what's happening?

	Thanks,
		Jerome

Stefan,

c-guess does just what I want (and need to remain socially acceptable). Thanks!
