* Cleanup SWIG_VERSION definitionWilliam S Fulton2022-10-133-19/+0
| | | | | | | | | | | | | Add Swig_obligatory_macros which must be called by each target language to define SWIG_VERSION correctly in the generated code, as well as the language specific macro SWIGXXX where XXX is the target language name. Drop the #ifdef SWIGXXX that was previously generated - I can't see the point of this and if users are defining this macro somehow, then users will need to change this Closes #1050
* Quick fix SWIG_VERSION not being defined correctly in wrappersWilliam S Fulton2022-10-131-1/+0

* Fix compile error when using directorsWilliam S Fulton2022-10-101-1/+1
| | | | | | | | Fix when using templates with more than one template parameter and used as an input parameter in a virtual method in a director class (problem affecting most of the scripting languages). Fixes #2160
* Sort out predefined SWIG-specific macrosOlly Betts2022-10-053-9/+19
| | | | | | | | | | | | | | | | | | | Ensure that SWIG_VERSION is defined both at SWIG-time and in the generated C/C++ wrapper code (it was only defined in the wrapper for some target languages previously). SWIGGO and SWIGJAVASCRIPT are now defined in the generated wrappers to match behaviour for all other target languages. Stop defining SWIGVERSION in the wrapper. This only happened as a side-effect of how SWIG_VERSION was defined but was never documented and is redundant. The new testcase also checks that SWIG is defined at SWIG-time but not in the generated wrapper, and that exactly one of a list of target-language specific macros is defined. Fixes #1050
* Provide SWIGTYPE MOVE typemaps in swigmove.iWilliam S Fulton2022-09-161-0/+19
| | | | | | | | | | | | 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
* Remove broken %implicitconv for const SWIGTYPE &&William S Fulton2022-09-051-24/+0
| | | | | | Typemaps should be for SWIGTYPE &&, not just const SWIGTYPE &&. Needs updating for new approach where the proxy object is moved for a parameter containing an rvalue reference.
* Remove unnecessary const SWIGTYPE & typemapWilliam S Fulton2022-09-051-9/+1
| | | | | This is a duplicate of SWIGTYPE & and the typemap rules result in SWIGTYPE & being used if there is no const SWIGTYPE & tyemap.
* SWIGTYPE && input typemaps now assume object has been movedWilliam S Fulton2022-08-311-3/+8
| | | | | | | | | | | | | | | | | | | | Replicated Java implementation. Fully implemented for: - C# - D - Guile - Javascript (UTL) - Lua - MzScheme - Octave (UTL) - Perl (UTL) - PHP - Python (UTL) - Ruby (UTL) - Tcl (UTL) PHP std::auto_ptr std::unique_ptr minor tweaks and testcase corrections

* Remove redundant check for NULL in char * typemapsWilliam S Fulton2022-07-241-3/+3
| | | | | | | No need to check for NULL before calling delete/free. Anyone using typemaps_string_alloc with custom allocators and deallocators need to ensure the custom allocators behave in the same way as the standard deallocators in this respect.
* Add Python support for std::unique_ptr inputsWilliam S Fulton2022-07-172-0/+2
| | | | Equivalent to Java/C# implementation.
* Performance optimisation for directors for classes passed by valueWilliam S Fulton2022-07-041-1/+1
| | | | | | | 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.
* Movable and move-only types supported in "out" typemaps.William S Fulton2022-06-301-2/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Issue #999 Closes #1044 More about the commit: Added some missing "varout" typemaps for Ocaml which was falling back to use "out" typemaps as they were missing. Ruby std::set fix for SwigValueWrapper C++11 changes.
* Correct warning message for wchar_t * typemapsWilliam S Fulton2022-05-063-3/+12

* Remove redundant conditionalOlly Betts2022-03-071-4/+0
| | | | | | | clang defines __GNUC__ and __GNUC_MINOR__ as if it were GCC 4.2.1 and has since clang 2.4, which was before __has_builtin() was added. Closes #1239

| | | | | | | | | | | | | | It's fairly hidden where it is, put it where users can see it more easily. Fixes #2166
* | Fix function prototypes of generated pointer functionsJustus Winter2022-02-031-2/+2
| | | | | | | | | | | | | | | | | | | | Previously, the emitted constructors were incomplete prototypes. When compiling the wrapper code using gcc 6 and -Wstrict-prototypes, the following warnings were emitted: warning: function declaration isn’t a prototype [-Wstrict-prototypes] See #801
* | Remove redundant NULL checks before free()/delete (#2184)Olly Betts2022-01-291-2/+2
|/ | | | | | | | | Remove redundant NULL checks before free()/delete The ISO C and C++ standards guarantee that it's safe to call these on a NULL pointer, so it's not necessary for the calling code to also check. Fixes https://sourceforge.net/p/swig/feature-requests/70/
* Member function pointer typemap tweaksWilliam S Fulton2021-04-261-7/+7
| | | | | | Use sizeof variable name rather than variable type. Workaround Visual C++ unable to parse some complex C++11 types, such as sizeof(short (Funcs::*)(bool) const &&)
* Fix typos in attribute2ref() in Lib/typemaps/attribute.swgZackery Spytz2021-02-091-1/+1

* Fix typecheck typemaps for non-pointers and NULLWilliam S Fulton2018-12-291-8/+8
| | | | | | | | | The typecheck typemaps succeed for non pointers (SWIGTYPE, SWIGTYPE&, SWIGTYPE&&) when the equivalent to C NULL is passed from the target language. This commit implements a fix for Python to not accept a Python None for non-pointer types. Issue #1202
* Remove -cppcast and -nocppcast command line optionsWilliam S Fulton2018-11-131-9/+2
| | | | | | | | | | | | | The -cppcast option is still turned on by default. The -nocppcast option to turn off the use of c++ casts (const_cast, static_cast etc) has been removed. However, defining SWIG_NO_CPLUSPLUS_CAST will still generate C casts instead of C++ casts for C++ wrappers. This a revert of commit fc79264a48f186f8bbd367e91fa9dbf9758aa092: "Revert "Remove -cppcast and -nocppcast command line options"" The Scilab and Javascript casting problems are now fixed, so -cppcast is now switched on as default.
* Fix constant function pointer typemapsWilliam S Fulton2018-11-131-0/+2
| | | | | | | | | The function pointer typemaps were not being used when the function pointer is const, like ADD_BY_VALUE_C in the funcptr_cpp.i testcase: %constant int (* const ADD_BY_VALUE_C)(const int &, int) = addByValue; Problem affecting Javascript and observable when running test-suite with -cppcast.

* Add unignore for rvalue ref-qualifiersWilliam S Fulton2017-08-301-69/+0
| | | | | | | | Use std::move on this pointer as the default approach to supporting rvalue ref-qualifiers if a user really wants to wrap. std::move requires <memory> headers so add swigfragments.swg for all languages to use common fragments. Just header file fragments for now.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The vector of pointers (just fixed) were not working correctly because the descriptors returned from swig::type_info() were sometimes returning zero. Zero should only be used for void * as the subsequent call to SWIG_ConvertPtr will blindly cast the pointer without checking descriptor. std::vector<void *> does not work and will require further changes: specializing traits_info<void *> to return 0 and traits_asptr<void *>. I tried this and traits_asptr<void> also needs to be added in which seems odd and requires further investigation... Lib/python/pystdcommon.swg: template <> struct traits_info<void *> { static swig_type_info *type_info() { static swig_type_info *info = 0; } }; Lib/std/std_common.i: template <> struct traits_asptr<void *> { static int asptr(PyObject *obj, void ***val) { void **p; swig_type_info *descriptor = 0; int res = SWIG_ConvertPtr(obj, (void **)&p, descriptor, 0); if (SWIG_IsOK(res)) { if (val) *val = p; } return res; } }; // this is needed, but am not sure this is expected template <> struct traits_asptr<void> { static int asptr(PyObject *obj, void **val) { void **p; swig_type_info *descriptor = 0; int res = SWIG_ConvertPtr(obj, (void **)&p, descriptor, 0); if (SWIG_IsOK(res)) { if (val) *val = p; } return res; } };
