LINE-TYPE specifies a type of line as described below, and INDENT-SPEC
says what \\[indent-for-comment] should do when used on that type of line.

The recognized values for LINE-TYPE are:

 anchored-comment  -- The line contains a comment that starts in column 0.
 end-block         -- The line contains a solitary block closing brace.

An INDENT-SPEC is a cons cell of the form:

 (ACTION . VALUE)

ACTION says how \\[indent-for-comment] should align the comment, and
VALUE is interpreted depending on ACTION.  ACTION can be any of the
following:

 space   -- Put VALUE spaces between the end of the line and the start
            of the comment.
 column  -- Start the comment at the column VALUE.  If the line is
            longer than that, the comment is preceded by a single
            space.  If VALUE is nil, `comment-column' is used.
 align   -- Align the comment with one on the previous line, if there
            is any.  If the line is too long, the comment is preceded
            by a single space.  If there isn't a comment start on the
            previous line, the behavior is specified by VALUE, which
            in turn is interpreted as an INDENT-SPEC.

If a LINE-TYPE is missing, then \\[indent-for-comment] indents the comment
according to `comment-column'.

If this variable is a string, it will be used in all CC Mode major

The regexp should match the prefix used in both C++ style line

\"//\" for line comments and the string in `c-block-comment-prefix',

 autodoc -- Pike autodoc style for \"//! ...\" comments (default in Pike mode).
 gtkdoc  -- GtkDoc style for \"/** ... **/\" comments

The value may also be a list of doc comment styles, in which case all

that don't conflict).

The value may also be an association list to specify different doc

 brace-else-brace    -- Clean up \"} else {\" constructs by placing
                        entire construct on a single line.  This clean

                        white space between the braces and the `else'.
                        Clean up occurs when the open brace after the
                        `else' is typed.
 brace-elseif-brace  -- Similar to brace-else-brace, but clean up
                        \"} else if (...) {\" constructs.  Clean up
                        occurs after the open parenthesis and the open
                        brace.
 brace-catch-brace   -- Similar to brace-elseif-brace, but clean up
                        \"} catch (...) {\" constructs.
 empty-defun-braces  -- Clean up empty defun braces by placing the
                        braces on the same line.  Clean up occurs when
                        the defun closing brace is typed.
 one-liner-defun     -- If the code inside a function body can fit in
                        a single line, then remove any newlines
                        between that line and the defun braces so that
                        the whole body becomes a single line.
                        `c-max-one-liner-length' gives the maximum
                        length allowed for the resulting line.  Clean
                        up occurs when the closing brace is typed.
 defun-close-semi    -- Clean up the terminating semi-colon on defuns
                        by placing the semi-colon on the same line as
                        the closing brace.  Clean up occurs when the
                        semi-colon is typed.
 list-close-comma    -- Clean up commas following braces in array
                        and aggregate initializers.  Clean up occurs
                        when the comma is typed.
 scope-operator      -- Clean up double colons which may designate
                        a C++ scope operator split across multiple
                        lines.  Note that certain C++ constructs can
                        generate ambiguous situations.  This clean up
                        only takes place when there is nothing but

                        when the second colon is typed.

The following clean ups always take place when they are on this list,
regardless of the auto-newline feature, since they typically don't
involve auto-newline inserted newlines:

 space-before-funcall -- Insert exactly one space before the opening
                        parenthesis of a function call.  Clean up
                        occurs when the opening parenthesis is typed.
 compact-empty-funcall -- Clean up any space before the function call
                        opening parenthesis if and only if the
                        argument list is empty.  This is typically
                        useful together with `space-before-funcall' to
                        get the style \"foo (bar)\" and \"foo()\".
                        Clean up occurs when the closing parenthesis
                        is typed.
 comment-close-slash -- When a slash is typed after the comment prefix
                        on a bare line in a c-style comment, the comment
                        is closed by cleaning up preceding space and

association list with elements of the following form:
\(SYNTACTIC-SYMBOL . ACTION).

When a brace (either opening or closing) is inserted, the syntactic
context it defines is looked up in this list, and if found, the
associated ACTION is used to determine where newlines are inserted.
If the context is not found, the default is to insert a newline both
before and after the brace.

SYNTACTIC-SYMBOL can be statement-cont, brace-list-intro,
inexpr-class-open, inexpr-class-close, and any of the *-open and
*-close symbols.  See `c-offsets-alist' for details, except for
inexpr-class-open and inexpr-class-close, which doesn't have any
corresponding symbols there.  Those two symbols are used for the
opening and closing braces, respectively, of anonymous inner classes
in Java.

ACTION can be either a function symbol or a list containing any
combination of the symbols `before' or `after'.  If the list is empty,
no newlines are inserted either before or after the brace.

When ACTION is a function symbol, the function is called with a two
arguments: the syntactic symbol for the brace and the buffer position
at which the brace was inserted.  The function must return a list as
described in the preceding paragraph.  Note that during the call to
the function, the variable `c-syntactic-context' is set to the entire

(defcustom c-offsets-alist nil
  "Association list of syntactic element symbols and indentation offsets.
As described below, each cons cell in this list has the form:

    (SYNTACTIC-SYMBOL . OFFSET)

When a line is indented, CC Mode first determines the syntactic
context of it by generating a list of symbols called syntactic
elements.  The global variable `c-syntactic-context' is bound to that
list.  Each element in the list is in turn a list where the first
element is a syntactic symbol which tells what kind of construct the
indentation point is located within.  More elements in the syntactic
element lists are optional.  If there is one more and it isn't nil,
then it's the anchor position for that construct.

After generating the syntactic context for the line, CC Mode
calculates the absolute indentation: First the base indentation is
found by using the anchor position for the first syntactic element
that provides one.  If none does, zero is used as base indentation.
Then CC Mode looks at each syntactic element in the context in turn.
It compares the car of the syntactic element against the
SYNTACTIC-SYMBOL's in `c-offsets-alist'.  When it finds a match, it
adds OFFSET to the base indentation.  The sum of this calculation is
the absolute offset for line being indented.

If the syntactic element does not match any in the `c-offsets-alist',
the element is ignored.

OFFSET can specify an offset in several different ways:

  If OFFSET is nil then it's ignored.

  If OFFSET is an integer then it's used as relative offset, i.e. it's
  added to the base indentation.

  If OFFSET is one of the symbols `+', `-', `++', `--', `*', or `/'
  then a positive or negative multiple of `c-basic-offset' is added to
  the base indentation; 1, -1, 2, -2, 0.5, and -0.5, respectively.

  If OFFSET is a symbol with a value binding then that value, which
  must be an integer, is used as relative offset.

  If OFFSET is a vector then its first element, which must be an
  integer, is used as an absolute indentation column.  This overrides
  the previous base indentation and the relative offsets applied to
  it, and it becomes the new base indentation.

  If OFFSET is a function or a lambda expression then it's called with
  a single argument containing the cons of the syntactic symbol and
  the anchor position (or nil if there is none).  The return value
  from the function is then reinterpreted as an offset specification.

  If OFFSET is a list then its elements are evaluated recursively as
  offset specifications.  If the first element is any of the symbols
  below then it isn't evaluated but instead specifies how the
  remaining offsets in the list should be combined.  If it's something
  else then the list is combined according the method `first'.  The
  valid combination methods are:

  `first' -- Use the first offset (that doesn't evaluate to nil).
  `min'   -- Use the minimum of all the offsets.  All must be either
             relative or absolute - they can't be mixed.
  `max'   -- Use the maximum of all the offsets.  All must be either
             relative or absolute - they can't be mixed.
  `add'   -- Add all the evaluated offsets together.  Exactly one of
             them may be absolute, in which case the result is
             absolute.  Any relative offsets that preceded the
             absolute one in the list will be ignored in that case.

`c-offsets-alist' is a style variable.  This means that the offsets on
this variable are normally taken from the style system in CC Mode
\(see `c-default-style' and `c-style-alist').  However, any offsets
put explicitly on this list will override the style system when a CC
Mode buffer is initialized (there is a variable
`c-old-style-variable-behavior' that changes this, though).

Here is the current list of valid syntactic element symbols:
