My .emacs defines a style like this:
(defconst qemu-c-style
'((indent-tabs-mode . nil)
(c-basic-offset . 4)
(tab-width . 8)
(c-comment-only-line-offset . 0)
(c-offsets-alist . ((statement-block-intro . +)
(substatement-open . 0)
(label . 0)
(statement-cont . +)
(innamespace . 0)
(inline-open . 0)
))
(c-hanging-braces-alist .
((brace-list-open)
(brace-list-intro)
(brace-list-entry)
(brace-list-close)
(brace-entry-open)
(block-close . c-snug-do-while)
;; structs have hanging braces on open
(class-open . (after))
;; ditto if statements
(substatement-open . (after))
;; and no auto newline at the end
(class-close)
))
)
"QEMU C Programming Style")
which is a superset of Stroustrup and gets a few more
corner cases right, I think.
