Document extern template functions support.
Extern templates result in new warning to differentiate
from template explicit instantiation definition warning.
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
Fixes parallel make where each invocation of swig was writing and
deleting the same file resulting in lots of the newly introduced
warning messages:
On exit, could not delete file xxx.py: No such file or directory
Parameter renaming is not fully implemented. Mainly because there is no
C/C++ syntax to
for %rename to fully qualify a function's parameter name from outside
the function. Hence it
is not possible to implemented targetted warning suppression on one
parameter in one function.
Issue #1420
This is the Doxygen work begun in Google Summer of Code projects 2008
and 2012 and subsequently improved by numerous contributors.

Fix -Wimplicit-fallthrough gcc-7.3 warning
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.
Internally, handle function ref-qualifiers in the function decl type string.
Needed for a whole host of things to work like %feature and %rename.
Add %feature %rename and %ignore testing for ref-qualifiers.
Fixes#1059
Methods with rvalue ref-qualifiers are ignored by default as it is not
possible to have an rvalue temporary from the target language (which is
needed to call the rvalue ref-qualified method).
A warning 405 is shown mentioning the ignored rvalue ref-qualifier method
which can be seen with the -Wextra option.
cpp_refqualifier.i:15: Warning 405: Method with rvalue ref-qualifier ignored h() const &&.
Usually rvalue and lvalue ref-qualifier overloaded methods are written - the
lvalue method will then be wrapped.
The scoping rules around %template have been specified and enforced.
The %template directive for a class template is the equivalent to an
explicit instantiation of a C++ class template. The scope for a valid
%template instantiation is now the same as the scope required for a
valid explicit instantiation of a C++ template. A definition of the
template for the explicit instantiation must be in scope where the
instantiation is declared and must not be enclosed within a different
namespace.
For example, a few %template and explicit instantiations of std::vector
are shown below:
// valid
namespace std {
%template(vin) vector<int>;
template class vector<int>;
}
// valid
using namespace std;
%template(vin) vector<int>;
template class vector<int>;
// valid
using std::vector;
%template(vin) vector<int>;
template class vector<int>;
// ill-formed
namespace unrelated {
using std::vector;
%template(vin) vector<int>;
template class vector<int>;
}
// ill-formed
namespace unrelated {
using namespace std;
%template(vin) vector<int>;
template class vector<int>;
}
// ill-formed
namespace unrelated {
namespace std {
%template(vin) vector<int>;
template class vector<int>;
}
}
// ill-formed
namespace unrelated {
%template(vin) std::vector<int>;
template class std::vector<int>;
}
When the scope is incorrect, an error now occurs such as:
cpp_template_scope.i:34: Error: 'vector' resolves to 'std::vector' and
was incorrectly instantiated in scope 'unrelated' instead of within scope 'std'.
Previously SWIG accepted the ill-formed examples above but this led to
numerous subtle template scope problems especially in the presence of
using declarations and using directives as well as with %feature and %typemap.
Actually, a valid instantiation is one which conforms to the C++03
standard as C++11 made a change to disallow using declarations and
using directives to find a template.
// valid C++03, ill-formed C++11
using std::vector;
template class vector<int>;
Similar fixes for defining classes using forward class references have
also been put in place. For example:
namespace Space1 {
struct A;
}
namespace Space2 {
struct Space1::A {
void x();
}
}
will now error out with:
cpp_class_definition.i:5: Error: 'Space1::A' resolves to 'Space1::A' and
was incorrectly instantiated in scope 'Space2' instead of within scope 'Space1'.
The way Python docstrings are indented has changed on master, so use the
standard inspect module in Python autodoc unit test to ignore the differences
in their indentation level between -builtin and non-builtin cases to make the
test still pass with the branch version, which avoids the use of different
(but almost identical) values in the test itself.
Updated Doxygen error numbers yet again, as Python errors got added in the
meanwhile, pushing the Doxygen ones further off.
And re-merged PEP8/whitespace-related conflicts in autodoc_runme.py once again
(if anybody is looking for a motivating example about why significant
whitespace is bad, here is a great use case).
Previously SWIG looked at the indentation of the first line and removed
that many characters from each subsequent line, regardless of what those
characters were. This was made worse because SWIG's preprocessor removes
any whitespace before a '#'. Fixes github issue #379, reported by Joe
Orton.
