%feature improvements for the syntax that takes the feature value within the
%feature() brackets. The value specified is no longer restricted to being just
a string. It can be a string or a number. For example, this is now acceptable
syntax:
%feature("featurename",20.0);
whereas previously it would have to have been:
%feature("featurename","20.0");
Useful for features that are implemented as a macro, for example:
#define %somefeature(value) %feature("somefeature",value)
These will now work accepting either a string or a number:
%somefeature("Fred");
%somefeature(4);

%feature enhancements. Features can now take an unlimited number of attributes
in addition to the feature name and feature value. The attributes are optional
and are much the same as the typemap attributes. For example, the following
specifies two optional attributes, attrib1 and attrib2:
%feature(featurename, attrib1="attribval1", attrib2="attribval2") name "val";
%feature(featurename, val, attrib1="attribval1", attrib2="attribval2") name;

syntax is as follows
%fragment("name","header") { /* an old fragment */ }
%fragment("name" {Type}, "header") { /* the fragment is type dependent */}
Now fragments can also be used inside templates:
template <class T>
struct A {
%fragment("incode"{A<T>},"header") {
/* 'incode' especialized fragment */
}
%typemap(in,fragment="incode"{A<T>}) {
/*
here we use the 'type especialized' fragment
"incode"{A<T> }
*/
}
};
Also, there is a minor templ.c fix when expanding '#T'.
git-svn-id: https://swig.svn.sourceforge.net/svnroot/swig/trunk@5749 626c5289-ae23-0410-ae9c-e8d60b6d4f22
%fragment("Hello","header") "..."
%fragment("Hi","header",fragment="Hello") "..."
the latter fragment will include the first one if is invoked.
more than one fragment can be included at the time, just
keep adding fragment="f1",fragment="f2", etc.
this is used to emulate typemaps reuse, where all the
reusable typemap code is put in a fragment static method,
and then it can be included from another fragment typemap
as needed.

WARN_PARSE_REDUNDANT 322
similar to the g++ -Wredundant-decls flag.
This recovers the warnings that now are not been reported by
the original code
WARN_PARSE_REDEFINED 302
Redundant example:
int foo(int);
int foo(int);
Redefined example:
int foo(int);
double foo(int);

Now, this doesn't generate warnings:
class A; class B*;
int foo(A*, B*);
struct A {
friend int foo(A*, B*);
};
but this generates
struct B {
friend double foo(A*, B*);
};
which is correct, since they have different return types.
See the redefined.i file for most cases where
repeated (but not redefined) declarations are
not generating warnings now, such as:
// no warning
#define REPEATED 1
#define REPEATED 1
// yes warning
#define REDEFINED 1
#define REDEFINED 2
this is following the C, C++ and preprocessor
standard behavior.
The function 'need_redefined_warn(..)' was added to
util.c, if some strange corner appears, and therefore,
the parser.y file doesn't need to be changed latter.
Also, the redefined warning format in parser.y
was changed, so now it respond to William's -Fmicrosoft
flag.

the function 'need_protected' outside parser.y,
ie, if more subtle cases appear, they can be
fixed without changing parser.y.
Now parser.y looks much more like the original 1.32.

Source/CParse/util.c: moving and fixing 'need_protected'
Examples/test-suite/director_protected.i: more %rename cases
Examples/test-suite/director_using.i: fixing bad module name
The errors in question where related to the mix of
%rename + (typedef|static) + protected + dirprot_mode:
%rename(s) Foo::p;
%rename(q) Foo::r;
%inline {
class Foo {
public:
virtual ~Foo() {}
int p(){ return 1;}
int r(){ return 1;}
protected:
typedef int q();
static int s();
};
since q and s look like functions, the parser was adding them
completly to the symbol table, and clashing latter with the
attemped renames.
The error was only visible when dirprot was enabled, with
the old behavior it was ok.

%inline %{
class Foo {
protected:
void x();
public:
void y();
};
%}
will work in plain or plain director mode, but it will complain the
same as before with director protected support.
The reason is that the parser emmits the warning, and at that stage it
is not possible to decide if the protected Foo::x() could or not
conflict with the renamed Foo::y(), since Foo::x() could be virtual,
even when no "virtual" attribute is used.
Core:
parser.y: Detect the dirprot mode and prevents the generation of
protected symbols at the parsing stage.
lang.cxx: Export the director_protected_mode for parser.y and the
director protected member detection is much cleaner.
main.cxx: Fix the -dirprot flag, it was working in SWIG_FEATURE but
not in the command line.(minor thing not relate to the error).
swigmod.h: added Lang::dirprot_mode() for cleaner detection.
utils.cxx: is_member_director() centralizes and improve the test.
Test suite:
protected_rename.i: added %inline, so it can compile now.
director_protected.i: more cases, checking using %rename.

class Foo {
public:
int Foo::bar(int x);
};
SWIG just drops the "Foo" prefix the method and continues (previously,
the declaration was ignored entirely).

in the code being wrapped, then a value is constructed which is
1+ the previous enum value. For example:
enum numbers { zero, one, seven=7, eight};
has enumvalue attributes of '0', 'zero+1', '7' and 'seven+1'
