The XML target language support is not in good shape and is likely to be
removed unless somebody steps up to bring it up to the expected standard
(it fails to even meet the criteria for "Experimental" currently).
Closes#2213
The directorin typemaps in the director methods now use std::move on the
input parameter when copying the object from the stack to the heap prior
to the callback into the target language, thereby taking advantage of
move semantics if available.
Enhance SWIGTYPE "out" typemaps to use std::move when copying
objects, thereby making use of move semantics when wrapping a function returning
by value if the returned type supports move semantics.
Wrapping functions that return move only types 'by value' now work out the box
without having to provide custom typemaps.
The implementation removed all casts in the "out" typemaps to allow the compiler to
appropriately choose calling a move constructor, where possible, otherwise a copy
constructor. The implementation alsoand required modifying SwigValueWrapper to
change a cast operator from:
SwigValueWrapper::operator T&() const;
to
#if __cplusplus >=201103L
SwigValueWrapper::operator T&&() const;
#else
SwigValueWrapper::operator T&() const;
#endif
This is not backwards compatible for C++11 and later when using the valuewrapper feature
if a cast is explicitly being made in user supplied "out" typemaps. Suggested change
in custom "out" typemaps for C++11 and later code:
1. Try remove the cast altogether to let the compiler use an appropriate implicit cast.
2. Change the cast, for example, from static_cast<X &> to static_cast<X &&>, using the
__cplusplus macro if all versions of C++ need to be supported.

Initial contributions for Linux provided in issue #1233, modified to work
on both Windows and Linux. Dual support is possible by detecting
the sizeof wchar_t which is different on each of these systems.
./configure now enables C++11 and later C++ standards testing by default (when
running: 'make check').
The options to control this testing are the same:
./configure --enable-cpp11-testing
./configure --disable-cpp11-testing
But the former is now the default and the latter can be used to turn off C++11 and
later C++ standards testing.
Reduce the number of tests on Appveyor by only running 32-bit (x86) using
latest Visual Studio (2022). Drop 32-bit Cygwin and MinGW testing.
Add C# and Java testing on VS2022 and drop Java testing on older Visual Studio.
This reduces the really long run times on Appveyor, however, VS2022 is
somewhat slower than older compilers.
If a "docstring" feature is present it will still override a Doxygen comment.
If the "autodoc" feature is also present, the combined "autodoc" and "docstring"
will override the Doxygen comment. If no "docstring" is present then the
"autodoc" feature will not be generated when there is a Doxygen comment.
This way the "autodoc" feature can be specified and used to provide documentation
for 'missing' Doxygen comments.
Closes#1635
This option was undocumented. If used it quietly did nothing
unless you'd installed the SWILL library before building SWIG, but
SWILL is no longer maintained and hasn't seen a release since
2008-04-10.
It's clear nobody has used this functionality for some time as the
code to support it in SWIG isn't actually valid ISO C++:
Modules/browser.cxx: In member function ‘void Browser::show_attributes(Node*)’:
Modules/browser.cxx:57:23: warning: ISO C++ forbids converting a string constant to ‘char*’ [-Wwrite-strings]
57 | char *trunc = "";

The debug command line options that display parse tree nodes
(-debug-module, -debug-top, -debug-symtabs) now display previously hidden
linked list pointers which are useful for debugging parse trees.
Added new command line option -debug-quiet. This suppresses the display
of most linked list pointers and symbol table pointers in the parse tree nodes.
The keys in the parse tree node are now shown in alphabetical order.
Problem when all the base class's overloaded methods were
overridden in the derived class - fixes "multiply defined" errors.
Linked lists of the overloaded methods were not set up correctly
when handling the using declaration.
Closes#2244
pyabc.i for abstract base classes now supports versions of Python

When C++ methods are not able to be overloaded in a derived class,
such as when they differ by just const, or the target language
parameters types are identical even when the C++ parameter types
are different, SWIG will ignore one of the overloaded methods with
a warning. A %ignore is required to explicitly ignore one of the
overloaded methods to avoid the warning message. Methods added
in the derived classes due to one of the %interface macros are now
similarly ignored/not added to the derived class.
The adding of additional methods into the parse tree is now more
robust and complete resulting in support for %feature and %rename
for the added methods.
Closes#1277
Fix using declaration in derived class incorrectly introducing a method
from a base class when the using declaration is declared before the method
declaration. Problem occurred when within a namespace and the parameter types
in the method signatures were not fully qualified.
Issue #1441
SWIG now handles an interface filename specified on the command line
which contains a closing parenthesis `)`, and more generally with
attributes to `%include` and `%import` which are quoted and contain
parentheses.
Fixes#1006
Fix SWIG_AsWCharPtrAndSize() to actually assign to result variable. It
looks like SWIG/Tcl wide character handling is currently fundamentally
broken except on systems which use wide characters as the system
encoding, but this should fix wrapping functions which take a wide
string as a parameter on Microsoft Windows.
Patch from Omar Medina.

SWIG python objects were being freed after the corresponding SWIG
module information was destroyed in Python 3, causing leaks when as
a result the object destructor could not be invoked. To prevent this
misordering, SWIG python objects now obtain a reference to the
Python capsule wrapping the module information, so that the module
information is correctly destroyed after all SWIG python objects
have been freed (and corresponding destructors invoked).
