35 ;; This package provides GNU Emacs major modes for editing C, C++,
|
|
|
36 ;; Objective-C, and Java code. As of the latest Emacs and XEmacs
|
|
|
37 ;; releases, it is the default package for editing these languages.
|
|
|
38 ;; This package is called "CC Mode", and should be spelled exactly
|
|
|
39 ;; this way. It supports K&R and ANSI C, ANSI C++, Objective-C, and
|
|
|
40 ;; Java, with a consistent indentation model across all modes. This
|
|
|
41 ;; indentation model is intuitive and very flexible, so that almost
|
|
|
42 ;; any desired style of indentation can be supported. Installation,
|
|
|
43 ;; usage, and programming details are contained in an accompanying
|
|
|
44 ;; texinfo manual.
|
|
|
45
|
|
|
46 ;; CC Mode's immediate ancestors were, c++-mode.el, cplus-md.el, and
|
|
|
47 ;; cplus-md1.el..

110
|
50 ;; coloring, keyword highlighting, etc.) for any of the supported
|
|
|
51 ;; modes. Typically this is done by a package called font-lock.el
|
|
|
52 ;; which I do *not* maintain. You should contact the Emacs
|
|
|
53 ;; maintainers for questions about coloring or highlighting in any

|
|
|
203 As described below, each cons cell in this list has the form:
|
|
|
204
|
|
|
205 (SYNTACTIC-SYMBOL . OFFSET)
|
|
|
206
|
|
110
|
207 When a line is indented, CC Mode first determines the syntactic
|
|
0
|
208 context of the line by generating a list of symbols called syntactic
|
|
|
209 elements. This list can contain more than one syntactic element and
|
|
|
210 the global variable `c-syntactic-context' contains the context list
|
|
|
211 for the line being indented. Each element in this list is actually a
|
|
|
212 cons cell of the syntactic symbol and a buffer position. This buffer
|
|
|
213 position is called the relative indent point for the line. Some
|
|
|
214 syntactic symbols may not have a relative indent point associated with
|
|
|
215 them.
|
|
|
216
|
|
110
|
217 After the syntactic context list for a line is generated, CC Mode
|
|
0
|
218 calculates the absolute indentation for the line by looking at each
|
|
|
219 syntactic element in the list. First, it compares the syntactic
|
|
|
220 element against the SYNTACTIC-SYMBOL's in `c-offsets-alist'. When it
|
|
|
221 finds a match, it adds the OFFSET to the column of the relative indent
|
|
|
222 point. The sum of this calculation for each element in the syntactic
|
|
|
223 list is the absolute offset for line being indented.
|
|
|
224
|
|
|
225 If the syntactic element does not match any in the `c-offsets-alist',
|
|
110
|
226 an error is generated if `c-strict-syntax-p' is non-nil, otherwise the
|
|
|
227 element is ignored.
|
|
0
|
228
|
|
|
229 Actually, OFFSET can be an integer, a function, a variable, or one of
|
|
|
230 the following symbols: `+', `-', `++', `--', `*', or `/'. These
|
|
|
231 latter designate positive or negative multiples of `c-basic-offset',
|
|
|
232 respectively: *1, *-1, *2, *-2, *0.5, and *-0.5. If OFFSET is a
|
|
|
233 function, it is called with a single argument containing the cons of
|
|
|
234 the syntactic element symbol and the relative indent point. The
|
|
|
235 function should return an integer offset.

|
|
236
