There are two ways to customize the indentation style for the C modes. First, you can select one of several predefined styles, each of which specifies offsets for all the syntactic symbols. For more flexibility, you can customize the handling of individual syntactic symbols. See section Syntactic Symbols, for a list of all defined syntactic symbols.
c-set-offset). The second argument offset specifies the new indentation offset.
c-offsets-alist variable controls the amount of
indentation to give to each syntactic symbol. Its value is an
association list, and each element of the list has the form
(syntactic-symbol . offset). By changing the offsets
for various syntactic symbols, you can customize indentation in fine
detail. To change this alist, use
c-set-offset (see below).
Each offset value in
c-offsets-alist can be an integer, a
function or variable name, or one of the following symbols:
--, indicating positive or negative
multiples of the variable
c-basic-offset. Thus, if you want to
change the levels of indentation to be 3 spaces instead of 2 spaces, set
c-basic-offset to 3.
Using a function as the offset value provides the ultimate flexibility
in customizing indentation. The function is called with a single
argument containing the
cons of the syntactic symbol and
the relative indent point. The function should return an integer
The command C-c C-o (
c-set-offset) is the easiest way to
set offsets, both interactively or in your `~/.emacs' file. First
specify the syntactic symbol, then the offset you want. See section Syntactic Symbols, for a list of valid syntactic symbols and their meanings.
