You may also need to add filetype plugin indent on to ~/.vimrc .
Explanation:
setlocal shiftwidth=4
Sets the autoindent spacing to 4 spaces. setlocal to limit this to the current (C++) buffer.
setlocal softtabstop=4
Sets the spacing for tab characters to 4 spaces.
setlocal expandtab
Always use spaces; never use tab characters.
setlocal textwidth=78
Limit the length of a line to 78 characters. Standard 4-6 actually specifies up to 110.
setlocal cino=:0,l1,g0,(0,u0,W2s
Set the C indent configuration.
- :0: Align case labels with the enclosing switch.
- l1: Indent statements relative to the case label, not anything following.
- g0: Align C++ scope (private/public) labels with the enclosing class.
- (0: Align lines after "(foo" next to the unclosed parenthesis.
- u0: Same as above for the next level of parentheses deeper.
- W2s: Indent lines following a line-terminating unclosed parenthesis by two shiftwidths (8 spaces)
setlocal comments^=s2:/**,mb:*,ex:*/
