 4;; Set emacs up for editing code using CVS indentation conventions.
 5;; See HACKING for more on what those conventions are.
 6;; To use, put in your .emacs:
 7;;   (load "c-mode")
 8;;   (load "cvs-format.el")
 9;; You need to load c-mode first or else when c-mode autoloads it will
10;; clobber the settings from cvs-format.el.  Using c-mode-hook perhaps would
11;; be a cleaner way to handle that.  Or see below about (set-c-style "BSD").

19;;	This section sets constants used by c-mode for formating
20;;
21;;
22
23;;  If `c-auto-newline' is non-`nil', newlines are inserted both
24;;before and after braces that you insert, and after colons and semicolons.
25;;Correct C indentation is done on all the lines that are made this way.

30;;*Non-nil means TAB in C mode should always reindent the current line,
31;;regardless of where in the line point is when the TAB command is used.
32;;It might be desirable to set this to nil for CVS, since unlike GNU
33;; CVS often uses comments over to the right separated by TABs.
34;; Depends some on whether you're in the habit of using TAB to
35;; reindent.

38;;; It seems to me that 
39;;;    `M-x set-c-style BSD RET'
40;;; or
41;;;    (set-c-style "BSD")
42;;; takes care of the indentation parameters correctly.
43
44
45;;  C does not have anything analogous to particular function names for which
46;;special forms of indentation are desirable.  However, it has a different
47;;need for customization facilities: many different styles of C indentation
48;;are in common use.
49;;
50;;  There are six variables you can set to control the style that Emacs C
51;;mode will use.
52;;
53;;`c-indent-level'     
54;;     Indentation of C statements within surrounding block.  The surrounding
55;;     block's indentation is the indentation of the line on which the
56;;     open-brace appears.
57
58(setq c-indent-level 4)
59
60;;`c-continued-statement-offset'     
61;;     Extra indentation given to a substatement, such as the then-clause of
62;;     an if or body of a while.
63
64(setq c-continued-statement-offset 4)
65
66;;`c-brace-offset'     
67;;     Extra indentation for line if it starts with an open brace.
68
69(setq c-brace-offset -4)
70
71;;`c-brace-imaginary-offset'     
72;;     An open brace following other text is treated as if it were this far
73;;     to the right of the start of its line.
74
75(setq c-brace-imaginary-offset 0)
76
77;;`c-argdecl-indent'     
78;;     Indentation level of declarations of C function arguments.
79
80(setq c-argdecl-indent 4)
81
82;;`c-label-offset'     
83;;     Extra indentation for line that is a label, or case or default.
84;;  This doesn't quite do the right thing for CVS switches, which use the
85;;    switch (foo)
86;;    {
87;;        case 0:
88;;            break;
89;;  style.  But if one manually aligns the first case, then the rest
90;;  should work OK.
