Go, Guile, Racket, Scilab: Add throws typemaps for std::string so that
thrown string exception messages can be seen.
Test all language for std::string throws typemaps
For implementing full move semantics when passing parameters by value.
Based on SWIGTYPE && and std::unique_ptr typemaps which implement move
semantics.
Added for all languages, but untested for: Go, Ocaml, R, Scilab (and
unlikely to be fully functional for same reasons as for std::unique_ptr
support).
Issue #999
Support running testcases conditional on the compiler supporting
a each language version, like we already handle C++11.
Currently no testcases are actually run in this way for these
newer language versions.
Most of these test D_d twice when they really should be testing
D_d once and D_i once (the variable name is `di` and the values
assigned are integers).
This was wrong in the initial version for Python in
708021a809 and it looks like subsequent
additions for other languages have just copied that mistake.
Change these typemaps to assume that after a function call,
the parameter has been moved. The parameter's proxy class
that owns the C++ object thus has the underlying pointer set
to null so the object cannot be used again and the object is deleted.
Scrap new javarelease typemap and move contents into javabody typemap.
This works by transferring ownership of the underlying C++ memory
from the target language proxy class to an instance of the unique_ptr
which is passed to the wrapped function via std::move.
The proxy class has a new swigRelease() method which sets the
underlying C++ pointer for the proxy class to null, so working
in much the same way as std::unique_ptr::release(). Any attempt at
using the proxy class will be the same as if the delete() function
has been called on the proxy class. That is, using a C++ null pointer,
when a non-null pointer is usually expected.
This commit relies on the previous commit that uses std::move
on the temporary variable used for the wrapped function's input parameter
as std::unique_ptr is not copyable, it has move-only semantics.
The C++ wrappers create a temporary variable for a parameter to be passed to a
function. This is initially default constructed and then copy assigned from the
instance being passed in from the target language. This is unchanged, however,
when the temporary variable is passed to wrapped function, it is now done using
std::move. If the type is move constructible, the move constructor will be used
instead of the copy constructor.
Note that the implementation calls std::move for all user-defined types
(non-primitive types passed by value), this excludes anything passed by pointer,
reference and arrays. It does also include any type that has not been
defined/parsed by SWIG, that is, unknown types. std::move is called via the
SWIG_STD_MOVE macro which only calls std::move for C++11 and later code.
This is the current state of play where the copy constructor and copy
assignment operators are called, even for movable types passed as
function parameters.
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.

CHANGES.current
Move HAVE_CXX11 into makefiles so that running test-suite
from top level directory or in the language's test-suite directory
is consistent. For example, running 'make check-java-test-suite'
behaves the same as 'cd Examples/test-suite/java && make check'.
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
Language::unrollVirtualMethods was assuming that the using
declaration would only introduce one method. Fix this by adding
in all the overloaded methods from a base class.
Affects code generation in C# and Java, but I was not able
to construct a test that failed before this commit.

setup catch2 framework (w/o tests)
This is done in preparation for adding namespace support to the Ruby
part of SWIG. Some existing test cases were reorganized or duplicated
for flat/nonflat nesting. For some a Ruby test script was added.
Finally the ruby/Makefile.in was improved so that for test cases
without an explicit test script, the generated wrapper library will
be loaded by the Ruby interpreter to ensure loading works fine.
The "endlink" command is processed in processWordCommands, which by
default skips space occuring after the command, which is intended for
removing leading space from a command argument. For "end" commands,
we don't want to do this. Note that certain end commands such as
"endcode" aren't processed by processWordCommands (believe
addCommandUnique ends up handling them).
Update usage of \link in doxygen_translate_all_tags.i to test handling
of space after \endlink.
Tweaking some of the usage in doxygen_misc_constructs.i to remove what
seems to be an extra space from the input (otherwise we would need to
add an extra space to the expected output).
In addition to the changes in the previous commit, also avoid syntax
errors in the generated Python docstrings by splitting them into several
parts if there are 3 quotes in a row in the input, as it's impossible to
have them inside triple-quoted strings, generally speaking (i.e. if
there are occurrences of both """ and ''' inside the string).
Single-line Doxygen comments ending with a double quote resulted in
syntactically-invalid Python docstrings in the output, so use triple
single quotes as delimiters in this case to avoid it.
