"Styles of indentation.
|
||
Elements of this alist are of the form:
|
||
|
||
(STYLE-STRING [BASE-STYLE] (VARIABLE . VALUE) [(VARIABLE . VALUE) ...])
|
||
|
||
where STYLE-STRING is a short descriptive string used to select a
|
||
style, VARIABLE is any Emacs variable, and VALUE is the intended value
|
||
for that variable when using the selected style.
|
||
|
||
Optional BASE-STYLE if present, is a string and must follow
|
||
STYLE-STRING. BASE-STYLE names a style that this style inherits from.
|
||
By default, all styles inherit from the \"user\" style, which is
|
||
computed at run time. Style loops generate errors.
|
||
|
||
Two variables are treated specially. When VARIABLE is
|
||
`c-offsets-alist', the VALUE is a list containing elements of the
|
||
form:
|
||
|
||
(SYNTACTIC-SYMBOL . OFFSET)
|
||
|
||
as described in `c-offsets-alist'. These are passed directly to
|
||
`c-set-offset' so there is no need to set every syntactic symbol in
|
||
your style, only those that are different from the default.
|
||
|
||
When VARIABLE is `c-special-indent-hook', its VALUE is added to
|
||
`c-special-indent-hook' using `add-hook'. If VALUE is a list, each
|
||
element of the list is added with `add-hook'.
|
||
|
||
Do not change this variable directly. Use the function `c-add-style'
|
||
to add new styles or modify existing styles (it is not a good idea to
|
||
modify existing styles -- you should create a new style that inherits
|
||
the existing style.")

STYLENAME is a string representing the desired style from the list of
|
||
styles described in the variable `c-style-alist'. See that variable
|
||
for details of setting up styles.
|
||
|
||
The variable `c-indentation-style' always contains the buffer's current

style name.
|

|
||
If the optional argument DONT-OVERRIDE is t, no style variables that
|

`c-offsets-alist', syntactic symbols will only be added, and in the
|
||
case of all other style variables, only those set to `set-from-style'
|
||
will be reassigned.
|
||
|
||
If DONT-OVERRIDE is neither nil nor t, only those style variables that
|
||
have default (i.e. non-buffer local) values will keep their settings
|
||
while the rest will be overridden. This is useful to avoid overriding
|
||
global settings done in ~/.emacs when setting a style from a mode hook
|
||
\(providing the style variables are buffer local, which is the
|
||
default).
|
||
|
||
Obviously, setting DONT-OVERRIDE to t is useful mainly when the

initial style is chosen for a CC Mode buffer by a major mode. Since

that is done internally by CC Mode, it typically won't have any effect
