Add bool output parameter to Swig_overload_dispatch to say when it has
generated code that will use the typecheck typemap code to help Lua and
Octave to not emit unused argv[] arrays.
Alas, resorted to warning suppression for deficient cpp11_initializer_list
typecheck typemap in cpp11_std_initializer_list testcase.
Complete the removal of Ruby's output_helper macro and replacement
with SWIG_AppendOutput for director typemaps.
Requires $isvoid special variable support in director code.
This provides a generic framework to aid converting C/C++ integer and
boolean literals to target language literals, replacing custom code in
several target language backends (and fixing some bugs in that code).
The $isvoid special variable expands to 1 if the
wrapped function has a void return, otherwise expands to 0.
In the implementation, use a consistent variable name, returntype,
for a node's "type" attribute.
Issue #2907
A different approach is taken for supporting casting smart pointers up the
inheritance hierarchy. We no longer try to replace the underlying pointer type,
provided in the 'feature:smartptr', with the base class type. Such as morphing
'std::shared_ptr<(Derived)>' into 'std::shared_ptr<(Base)>'. Instead, we simply
use 'feature:smartptr' from the base class. This is more reliable than trying to
pattern match the pointer type in the feature. The base class must of course
also have the 'feature:smartptr' set, and this is still checked for as before.
The feature is now parsed in one place and stored in the parse tree in the
new 'smart' attribute for handling by the target languages.
Fix also improves the handling of the type parsed in 'feature:smartptr' in that
the type is now normalized and resolved in the scope of the class it is attached
to.
Closes#2768
Avoids confusion with newly created Allocate::is_assignable.
Language::is_immutable is just a wrapper around the
"feature:immutable" flag since previous commit.

Further corrections to pass SwigType * to methods expecting types
instead of passing readable type strings.
Swig_string_mangle() takes a generic String *, but it was calling
functions that require SwigType *. Swig_string_mangle_type() is
now provided for SwigType *r. The special template handling
on types now occurs in this function.
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
Exit() is a wrapper for exit() by default, but SetExitHandler() allows
specifying a function to call instead.
This means that failures within DOH (e.g. Malloc() failing due to lack
of memory) will now perform cleanup such as removing output files.
This commit also cleans up exit statuses so SWIG should now reliably
exit with status 0 if the run was successful and status 1 if there was
an error (or a warning and -Werror was in effect).
Previously in some situations SWIG would try to exit with the status set
to the number of errors encountered, but that's problematic - for
example if there were 256 errors this would result in exit status 0 on
most platforms. Also some error statuses have special meanings e.g.
those defined by <sysexits.h>.
Also SWIG/Javascript tried to exit with status -1 in a few places (which
typically results in exit status 255).
These were officially deprecated in 2001, and attempts to use them have
resulted in a warning (including a pointer to what to update them to)
for most if not all of that time.
Fixes#1984
- Since (at least) Octave 5.1.0, the Octave error() function now raises a C++
exception, which if uncaught immediately exits a SWIG wrapper function,
bypassing any cleanup code that may appear after a "fail:" label.
- This patch adds a "try { ... } catch(...) { }" block around the contents of
SWIG wrapper functions to first execute the cleanup code before rethrowing any
exception raised.
- It is backward compatible with earlier versions of Octave where error() does
not raise an exception, which will still branch to the "fail:" block to
execute cleanup code if an error is encountered.
Backport changes to Python version of make_autodocParmList() to Ruby and
Octave modules, which use similar code.
In particular, this improves handling of parameters clashing with the
language keywords/reserved words for these languages as well.
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.
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.
- Fixes generation of director method declarations containing C++11 ref-qualifiers.
- Fixes generation of director method declarations returning more complex types such
as const ref pointers.
- Rewrite Swig_method_call to use more up to date code in the core.
The directorin typemaps will now generate a temporary variable
(specified after the type), such as:
%typemap(directorin) MyType (MyType *temp) { ... use temp ... }
The shared_ptr director typemaps have been fixed for use in functions
that take more than one parameter.
- Restructure runtime code into declarations, function
and class definitions, and initialisation code
- Rename internal functions/types to follow SWIG_Octave...
or SwigOct... naming styles
- Style/comment/whitespace cleanups
- Used "astyle -A10 -s2 -N -p -H -U -k1" for style cleanup
- Replaced NewString("") with NewStringEmpty()
- Used 'w' instead of 'f' for Wrapper() objects
