SWIG (Simplified Wrapper and Interface Generator)
Tagline: SWIG is a compiler that integrates C and C++ with languages
including Perl, Python, Tcl, Ruby, PHP, Java, C#, D, Go, Lua,
Octave, R, Scheme (Guile, MzScheme/Racket), Scilab, Ocaml.
SWIG can also export its parse tree into XML.
SWIG reads annotated C/C++ header files and creates wrapper code (glue
code) in order to make the corresponding C/C++ libraries available to
the listed languages, or to extend C/C++ programs with a scripting
language.
Up-to-date SWIG related information can be found at
https://www.swig.org
A SWIG FAQ and other hints can be found on the SWIG Wiki:

License
=======
Please see the LICENSE file for details of the SWIG license. For
further insight into the license including the license of SWIG's
output code, please visit
https://www.swig.org/legal.html
Release Notes
=============
Please see the CHANGES.current file for a detailed list of bug fixes and
new features for the current release. The CHANGES file contains bug fixes
and new features for older versions. A summary of changes in each release
can be found in the RELEASENOTES file.
Documentation
=============
The Doc/Manual directory contains the most recent set of updated
documentation for this release. The documentation is available in
three different formats, each of which contains identical content.
These format are, pdf (Doc/Manual/SWIGDocumentation.pdf), single
page html (Doc/Manual/SWIGDocumentation.html) or multiple page html
(other files in Doc/Manual). Please select your chosen format and
copy/install to wherever takes your fancy.
There is some technical developer documentation available in the
Doc/Devel subdirectory. This is not necessarily up-to-date, but it
has some information on SWIG internals.
Documentation is also online at
https://www.swig.org/doc.html.
Backwards Compatibility
=======================
The developers strive their best to preserve backwards compatibility
between releases, but this is not always possible as the overriding
aim is to provide the best wrapping experience. Where backwards
compatibility is known to be broken, it is clearly marked as an
incompatibility in the CHANGES and CHANGES.current files.
See the documentation for details of the SWIG_VERSION preprocessor
symbol if you have backward compatibility issues and need to use more
than one version of SWIG.
Installation
============
Please read the Doc/Manual/Preface.html#Preface_installation for
full installation instructions for Windows, Unix and Mac OS X
using the release tarball/zip file. The INSTALL file has generic
build and installation instructions for Unix users.
Users wishing to build and install code from Github should
visit
https://swig.org/svn.html to obtain the more detailed
instructions required for building code obtained from Github - extra
steps are required compared to building from the release tarball.
Testing
=======
The typical 'make -k check' can be performed on Unix operating systems.
Please read Doc/Manual/Preface.html#Preface_testing for details.
Examples
========
The Examples directory contains a variety of examples of using SWIG
and it has some browsable documentation. Simply point your browser to
the file "Example/index.html".
The Examples directory also includes Visual C++ project 6 (.dsp) files for
building some of the examples on Windows. Later versions of Visual Studio
will convert these old style project files into a current solution file.
Known Issues
============
There are minor known bugs, details of which are in the bug tracker, see
https://www.swig.org/bugs.html.
Troubleshooting
===============
In order to operate correctly, SWIG relies upon a set of library
files. If after building SWIG, you get error messages like this,
$ swig foo.i
:1. Unable to find 'swig.swg'
:3. Unable to find 'tcl8.swg'
it means that SWIG has either been incorrectly configured or
installed. To fix this:
1. Make sure you remembered to do a 'make install' and that
the installation actually worked. Make sure you have
write permission on the install directory.
2. If that doesn't work, type 'swig -swiglib' to find out
where SWIG thinks its library is located.
3. If the location is not where you expect, perhaps
you supplied a bad option to configure. Use
./configure --prefix=pathname to set the SWIG install
location. Also, make sure you don't include a shell
escape character such as ~ when you specify the path.
4. The SWIG library can be changed by setting the SWIG_LIB
environment variable. However, you really shouldn't
have to do this.
If you are having other troubles, you might look at the SWIG Wiki at
https://github.com/swig/swig/wiki.
Participate!
============
Please report any errors and submit patches (if possible)! We only
have access to a limited variety of hardware (Linux, Solaris, OS-X,
and Windows). All contributions help.
If you would like to join the SWIG development team or contribute a
language module to the distribution, please contact the swig-devel
mailing list, details at
https://www.swig.org/mail.html.

[Python] #2494 Fix integer overflow / undefined behavior for python
castmode on sizeof(long)==8 platforms for implicit conversions around
edge cases of LONG_MAX and ULONG_MAX, for example:
void as_l(long x); // C interface
Usage from Python:
lmaxd = math.nextafter(float(2**63), 0.0) # LONG_MAX == 2**63-1
# Now below correctly raises a TypeError due to the overflow
as_l(math.nextafter(lmaxd, float('inf')))

[PHP] `%feature("php:allowdynamicproperties", 0) Foo;` is now handled as
the feature being off to match other boolean features. Previously
any value set was treated as on.
2023-12-20: treitmayr
[Ruby] #2033 Fix missing checks for negative numbers when passing numbers
to unsigned long/unsigned long long C types.
2023-12-20: crhilton
[C#] #2722 Add support the "cs:defaultargs" feature.
This adds a way to wrap C++ functions that have default arguments
with an equivalent C# function with default arguments, instead of
generating an overloaded C# method for each defaulted argument.
2023-12-20: vadz, vadimcn, wangito33, wsfulton, clintonstimpson
[Python] #1613 #1687 #1727 #2190 #2727 #2428 Add support for the Python stable
ABI using default Python options. Code is generated that compiles when
setting the C macro Py_LIMITED_API to 0x03040000 (at C/C++ compile time).
Note that the -builtin, -fast (used by -O) options are not supported.
2023-12-20: wsfulton
[Python] More efficient input string marshalling for Python 3.
Previously a copy of a string was made while converting from a Python 3
string to a char * or std::string. This copy is no longer needed making
string marshalling more efficient. Does not apply to the stable ABI
targetting Python < 3.10 where a copy is still required where the stable
ABI does not provide PyUnicode_AsUTF8AndSize.
2023-12-20: wsfulton
#2190 Replace SWIG_Python_str_AsChar with SWIG_PyUnicode_AsUTF8AndSize.
SWIG_Python_str_AsChar has undefined behaviour when Py_LIMITED_API is defined
as it returns a pointer to a string in a PyBytes object that no longer exists.
SWIG_PyUnicode_AsUTF8AndSize is an efficient replacement, but requires a
different API and the caller to decrement the refcount on the intermediate
PyObject in the Py_LIMITED_API < 0x030A0000 implementation. The alternative
would have required copying the returned char * string as was done in a
previous implementation requiring a call to the defunct SWIG_Python_str_DelForPy3
function.

2023-12-14: PaulObermeier
[Tcl] #2730 Rename SWIG’s Tcl_GetBoolFromObj() since Tcl 8.7 (TIP 618)
introduces a function with the same name.
2023-12-13: chrstphrchvz
[Tcl] #2729 Use Tcl_GetString() instead of Tcl_GetStringFromObj(…, NULL)
for compatibility with Tcl 9.
2023-12-03: olly
[Ocaml] Remove -suffix command line option which has emitted a
deprecation warning since SWIG 3.0.4 - if you want to specify
a different filename extension for generated C++ files use -cppext
instead, which works for all SWIG target language backends.
2023-12-01: saiarcot895
[Python] #2413 Prevent potential multi-threading crash; gracefully exit running
daemon threads on main thread exit.
2023-11-24: wsfulton
Add support for parsing C++20 constexpr destructors.
2023-11-19: olly
Fix handling of constant expressions containing < and > to not
drop parentheses around the subexpression as doing so can change
its value in some cases.
2023-11-18: yasamoka, jmarrec
[Python] #2639 Add std_filesystem.i for wrapping std::filesystem::path
with pathlib.Path.
2023-11-17: chrstphrchvz
[Tcl] #2711 Fix -Wmissing-braces warning in generated code.
2023-11-17: chrstphrchvz
[Tcl] #2710 Stop using Tcl's CONST macro. It's no longer needed
and is set to be deprecated in Tcl 8.7, and removed in Tcl 9.0.
2023-11-08: wsfulton
[C#] Replace empty() method with IsEmpty property for std::vector, std::list, std::map
containers for consistency across all containers.
The empty() method is actually still wrapped, but as a private proxy method. For backwards
compatibility, the method can be made public again using %csmethodmodifiers for all
vectors as follows:
%extend std::vector {
%csmethodmodifiers empty() const "public"
}
%include "std_vector.i"
or alternatively for each individual %template instantiation as follows:
%csmethodmodifiers std::vector<double>::empty() const "public"
%template(VectorDouble) std::vector<double>;
*** POTENTIAL INCOMPATIBILITY ***
2023-11-08: wsfulton
[C#] Add std_unordered_set.i for wrapping std::std_unordered_set, implementing
C# System.Collections.Generic.ISet<>.
2023-11-09: olly
#2591 SWIG now supports command line options -std=cXX and
-std=c++XX to specify the C/C++ standards version. The only effect
of these options is to set appropriate values for __STDC_VERSION__
and __cplusplus respectively, which is useful if you're wrapping
headers which have preprocessor checks based on their values.
2023-11-09: olly
SWIG now defines __STDC__ to 1 to match the behaviour of ISO C/C++
compilers - previously it had an empty value.
*** POTENTIAL INCOMPATIBILITY ***
2023-11-09: olly
When -c++ is used, SWIG now defines __cplusplus to be 199711L (the
value for C++98) by default - previously its value was set to
__cplusplus.
*** POTENTIAL INCOMPATIBILITY ***
2023-11-08: emmenlau
#2480 [C#] Add std_unordered_map.i for wrapping std::std_unordered_map, implementing
C# System.Collections.Generic.IDictionary<>.
2023-11-06: wsfulton
[D, Java] Add the dbegin option to the %module directive for generating code at
the beginning of every D file. Similarly javabegin for Java. This enables one
to add a common comment at the start of each D/Java file.
2023-11-06: wsfulton
[C#] #2681 Support nullable reference types. A generic C# option to the
%module directive allows one to add in any code at the beginning of every
C# file. This can add the #nullable enable preprocessor directive at the beginning
of every C# file in order to enable nullable reference types as follows:
%module(csbegin="#nullable enable\n") mymodule
2023-10-21: wsfulton
[Python] #1783 Don't swallow all exceptions into a NotImplemented return
when wrapping operators which are marked with %pythonmaybecall. Corrects the
implementation of PEP 207.
2023-10-18: wsfulton
[C#, D] #902 Use the C++11 enum base, that is, the underlying enum
type.
For C#, it is used as the underlying type in the generated C# enum.
For D, it is used as the enum base type in the generated D enum.
2023-10-16: wsfulton
#2687 Another using declarations fix for inheritance hierarchies more than
two deep and the using declarations are overloaded. Using declarations
from a base class' base were not available for use in the target
language when the using declaration was before a method declaration.
2023-10-11: wsfulton
[C#, D, Go, Guile, Java, Javascript, Lua, Ocaml, R, Racket] #1680
carrays.i library modified to use size_t instead of int for the functions
provided by %array_functions and %array_class.
If the old types are required for backwards compatibility, use %apply to
restore the old types as follows:
%include "carrays.i"
%apply int { size_t nelements, size_t index }
... %array_functions and %array_class ...
%clear size_t nelements, size_t index; # To be safe in case used elsewhere
*** POTENTIAL INCOMPATIBILITY ***

[PHP] #2685 Fix testcase director_finalizer to work with PHP 8.3.
2023-10-06: wsfulton
#2307 std::vector::capacity and std::vector::reserve signature changes.
Java api changes from:
public long capacity() { ... }
public void reserve(long n) { ... }
to:
public int capacity() { ... }
public void reserve(int n) { ... }
to fit in with the usual Java convention of using int for container
indexing and sizing.
The original api for std::vector::reserve can be also be made available via
%extend to add in an overloaded method as follows:
%include <std_vector.i>
%extend std::vector {
void reserve(jlong n) throw (std::length_error, std::out_of_range) {
if (n < 0)
throw std::out_of_range("vector reserve size must be positive");
self->reserve(n);
}
}
This change is partially driven by the need to seamlessly support the full
64-bit range for size_t generically, apart from the customisations for the
STL containers, by using:
%apply unsigned long long { size_t };
%apply const unsigned long long & { const size_t & };
*** POTENTIAL INCOMPATIBILITY ***
2023-10-05: wsfulton
[C#] #2379 Defining SWIGWORDSIZE64 now applies the (unsigned)
long long typemaps to (unsigned) long for a better match on systems
where long is 64-bits. A new "Type mapping" section has been added into
the CSharp.html documentation covering this and marshalling of primitive
types. C (unsigned) long handling remains as is by default, that is,
marshall as 32-bit.
The INPUT[], OUTPUT[], INOUT[], FIXED[] typemaps for long and unsigned long
in arrays_csharp.i can now be used and compiled on 64-bit platforms where
sizeof(long) != sizeof(int). Requires SWIGWORDSIZE64 to be defined.
2023-09-27: wsfulton
[Java] #646 #649 Defining SWIGWORDSIZE64 now applies the (unsigned)
long long typemaps to (unsigned) long for a better match on systems

2023-09-11: wsfulton
[R] #2605 Complete transition to rtypecheck typemaps from hard coded
logic. Also see entry dated 2022-10-28 for swig-4.1.1. The rtypecheck
typemaps implement typechecking in R for each function parameter using
functions such as is.numeric, is.character, is.logical, is.null etc.

Fix incorrect variable setters being generated when wrapping arrays.
A setter is no longer generated if the type of the array members
are non-assignable.
2023-09-09: wsfulton
Non-assignable detection fixes when wrapping const member variables.
Const member variables such as the following are non-assignable by
by default:
char * const x;
const int x;
const int x[1];
but not:
const char * x;
Variable setters are not generated when wrapping these non-assignable
variables and classes containing such non-assignable variables.
2023-09-07: wsfulton
Non-assignable detection fixes when wrapping rvalue reference variables.
Rvalue reference variables such as the following are non-assignable by
by default:
X &&v;
Variable setters are not generated when wrapping these non-assignable

2023-09-06: wsfulton
Non-assignable detection fixes when wrapping reference variables.
Reference variables such as the following are non-assignable by

2023-09-06: wsfulton
Assignment operator detection fixes when wrapping static member
variables.
2023-09-06: wsfulton
#1416 Implicit assignment operator detection fixes.
A class that does not have an explicit assignment operator does not
have an implicit assignment operator if a member variable is not
assignable. Similarly should one of the base classes also not be
assignable. Detection of these scenarios has been fixed so that when
wrapping a variable that is not assignable, a variable setter is not
generated in order to avoid a compiler error.
Template instantiation via %template is required in order for this to
work for templates that are not assignable.
2023-09-03: wsfulton
https://sourceforge.net/p/swig/bugs/1006/
Fix incorrect variable setters being generated when the type of the
variable is not assignable, due to variable type inheriting a private
assignment operator further up the inheritance chain (further up than
the immediate base).
2023-09-03: wsfulton
[Guile, Ocaml, Perl] Don't attempt to generate a setter when wrapping
variables which have a private assignment operator as assignment is not
possible. This now matches the behaviour of all the other target languages.
2023-09-02: wsfulton
Fix problems wrapping deleted destructors. Derived classes are not
constructible, so don't attempt to generate default constructor or
copy constructor wrappers.
struct StackOnly1 {
// Only constructible on the stack
~StackOnly1() = delete;
};
struct StackOnlyDerived1 : StackOnly1 {
// this class is not constructible due to deleted base destructor
};

[Ruby] Remove -feature command line option which has been
deprecated since SWIG 1.3.32 in 2007. Use -initname instead.
2023-08-06: wsfulton
Add support for using declarations to introduce templated member
methods and for inheriting templated constructors, such as:
struct Base {
// templated constructor
template <typename T> Base(const T &t, const char *s) {}
// templated member method
template <typename T> void template_method(const T &t, const char *s) {}
};
%template(Base) Base::Base<int>;
%template(template_method) Base::template_method<double>;
struct Derived : Base {
using Base::Base;
using Base::template_method;
};
Previously the templated methods and constructors were ignored and
not introduced into the Derived class.
2023-08-04: wsfulton
Fix using declarations for inheritance hierarchies more than
two deep and the using declarations are overloaded. Using declarations
from a base class' base were not available for use in the target
language. For example in the code below, Using1::usingmethod(int i)
was not wrapped for use in Using3:
struct Using1 {
protected:
void usingmethod(int i) {}
};
struct Using2 : Using1 {
protected:
void usingmethod(int i, int j) {}
using Using1::usingmethod;
};
struct Using3 : Using2 {
void usingmethod(int i, int j, int k) {}
using Using2::usingmethod;
};
Similarly for C++11 using declarations for inheriting constructors.
2023-08-02: wsfulton
https://sourceforge.net/p/swig/bugs/932/
Fix missing constructor generation due to abstract class test
failure when a method is declared in the class along with a
using declaration and the using declaration is declared before
the method that implemented the pure virtual method, such as:
struct ConcreteDerived : AbstractBase {
ConcreteDerived() {} // was not wrapped
using AbstractBase::f;
virtual void f(int n) override {}
};

[PHP] Implement overloading between different integer types and
between double and float.
2023-07-29: wsfulton
https://sourceforge.net/p/swig/bugs/678/
Fix %copyctor used on class hierarchies with non-const copy
constructors. Previously SWIG always attempted to call a copy
constructor taking a const reference parameter instead of a
non-const reference parameter.
2023-07-28: wsfulton
#2541 Fix overloading of templated constructors and %copyctor.
2023-07-21: wsfulton
Don't generate a default constructor wrapper when a class has a
templated constructor, as there isn't actually an implied default
constructor. For example:
struct TConstructor3 {
template<typename T> TConstructor3(T val) {}
};
Previously wrappers were generated for a non-existent default
constructor which failed to compile.
2023-07-15: wsfulton
C++11 using declarations for inheriting constructors has now been
extended to support the directors feature.
2023-07-13: wsfulton

[Java] Remove deprecated command line options which have done
nothing except emit a deprecation message since 2002 or before:

[Guile] Drop support for -Linkage ltdlmod which was only useful
for Guile <= 1.4 which we no longer support.
2023-06-15: olly
[Guile] The -gh and -scm command line options have been removed.

2023-06-15: olly
SWIG will no longer fall back to using the include path to find the
input file, which has been deprecated and emitted a warning since
SWIG 1.3.37 (2009-01-13). This makes the behaviour of SWIG the
same as C/C++ compilers and works with ccache.
2023-06-15: olly
Remove features deprecated in SWIG 1.x and 2.x. Most of these have
emitted a deprecation warning or error for well over a decade and
have replacements with fewer shortcomings so we expect users will
have migrated away from them long ago, but in case you need

[Guile] Fix freearg typemaps to go with char **INOUT and char
*INOUT in typemaps. Previously the char **INOUT typemap would
leak memory if must_free$argnum was true, and the char *INOUT
typemap would generate code that didn't compile.
2023-06-07: olly
#2630 Fix preprocessor handling of a slash immediately followed by
a single quote, which wasn't getting recognised as starting a
character literal.
2023-06-07: olly
#2630 Fix parsing of <= and >= in templated lambda.
Skipping between matching delimiters is now done at the token level
rather than the character level.
2023-06-02: mmomtchev
[Javascript] #2622 Fix support for %typemap(default) and improve
support for default arguments in general.
2023-06-01: olly
[Perl] #2470 Fix some integer truncation warnings in generated
wrappers.
2023-05-30: olly
[Lua] Fix bug when passing a Lua number to a C++ function expected
std::string. Order of evaluation of C++ function arguments is not
defined, and if lua_rawlen() was called before lua_tostring() then
it would return 0 (because the value was still a number) and an
empty string would be passed.
2023-05-30: mmomtchev
[Javascript] #2618 Fix handling of C++ pointer to member function.
2023-05-25: olly
#1032 Allow typename disambiguator in:
using typename NodeT::links_type;
2023-05-25: olly
SWIG now discriminates between long double, double and float
constants. For example, this means that for target languages which
support a separate float type (such as C# and D) this will now
create a float constant instead of a double constant in the target
language:
#define PI_ISH 3.1414f
2023-05-25: olly
C++11 `auto` variables and `decltype()` can now deduce the
type of some expressions which involve literals of built-in types.
2023-05-25: olly
#1125 Support parsing C++11 auto variables. This uses the
existing type deduction code from decltype so has the same
limitations, and such variables will only actually be wrapped
when SWIG can deduce the type.
2023-05-23: olly
[Ruby] Fix deprecation warnings about ANYARGS when compiling
C++ code for SWIG-generated Ruby wrappers with Ruby 3.x.
This is a recurrence of a problem fixed in 4.0.2. Our fix was
conditional on RB_METHOD_DEFINITION_DECL being defined, but Ruby
3.0 stopped defining this.
2023-05-23: olly
#2606 Improve error output when SWIG reaches EOF while looking for
a closing delimiter. This is reported with an error like:
Error: Missing '}'. Reached end of input.
We now exit after reporting this and so no longer report a second
more generic error like:
Error: Syntax error in input(1).
2023-05-22: mmomtchev
[Javascript] #2600 Improve test coverage by adding _runme.js files
for 22 test cases.
2023-05-20: erezgeva
[C#, D, Java, Javascript, Guile, Scilab] #2552 Implement argcargv.i
library multi-argument typemaps.
2023-05-20: erezgeva
[D] #56 #2538 #2570 The generated code now works with recent D releases:
adds override keyword on overridden methods.
Support is now working using DMD, gcc D and LLVM D compilers.
2023-05-20: olly
Support deducing the type for decltype(false) and
decltype(true).
2023-05-19: olly
#2446 Add support for auto without trailing return type, which is a
C++14 feature.
2023-05-19: olly
SWIG no longer defines preprocessor symbols corresponding to
command line options (e.g. `-module blah` was resulting in
`SWIGOPT_MODULE` being set to `blah`). This feature was added in
2001 so that "[m]odules can look for these symbols to alter their
code generation if needed", but it's never been used for that
purpose in over 20 years, and has never been documented outside of
CHANGES.
2023-05-18: olly
#2591 Add new -U command line option to undefine a preprocessor
symbol.
2023-05-18: olly
#1589 #2335 Support parsing arbitrary expression in decltype.
Use parser error recovery to skip to the closing matching `)` and
issue a warning that we can't deduce the decltype for the
expression (like we already do for any expression which isn't a
simple variable or similar).
2023-05-12: mmomtchev, erezgeva
[Javascript] #2561 Support check typemaps for Javascript.
2023-05-12: olly
[Java] #2556 Suppress Java removal warnings on finalize method.
SWIG will need to stop relying on finalize methods, but we know
that and meanwhile these warnings make the testsuite output very
noisy.
2023-05-11: olly
#302 #2079 #2474 Parse storage class more flexibly.
Previously we had a hard-coded list of allowed combinations in the
grammar, but this suffers from combinatorial explosion, and results
in a vague `Syntax error in input` error for invalid (and missing)
combinations.
This means we now support a number of cases which are valid C++ but
weren't supported, including `friend constexpr` and `virtual
explicit`.
2023-05-08: olly
#1567 Add support for std::string_view (new in C++17) for C#, Java,
Lua, Perl, PHP, Python, Ruby and Tcl.
2023-05-08: olly
[PHP] #2544 Wrap overloaded method with both static and non-static
forms. We now wrap this as a non-static method in PHP, which means
the static form is only callable via an object.
Previously this case could end up wrapped as static or non-static
in PHP. If it was wrapped as static, attempting to call non-static
overloaded forms would crash with a segmentation fault.
2023-05-06: mmomtchev, wsfulton
#2550 Fix typedef/using declarations to a typedef struct/class.
2023-05-04: erezgeva
[D] #2538 Drop support for D1/Tango, which was discontinued in
2012. Wrappers for D2/Phobos are now generated by default, though
the -d2 command line option is still accepted (and now ignored) for
backward compatibility.
*** POTENTIAL INCOMPATIBILITY ***
2023-04-27: olly
#2502 Allow using snprintf() instead of sprintf() in wrappers.
We aim to produce code that works with C90 or C++98 so we can't
assume snprintf() is available, but it almost always is (even
on systems from before it was standardised) so having a way to
use it is helpful.
We enable this automatically if the compiler claims conformance
with at least C99 or C++11. It can also be enabled manually by
defining SWIG_HAVE_SNPRINTF. Define SWIG_NO_SNPRINTF to disable
completely.
The fallback is to call sprintf() without a buffer size check,
which is what we've done until now. Adding a check after the
call seems of limited benefit - if the buffer was overflowed
then it's too late to block it, and most of our uses either have a
fixed maximum possible size or dynamically allocate a buffer that's
large enough.
2023-04-26: mmomtchev
[Javascript] Take into account numinputs when counting arguments.
2023-04-24: olly
[PHP] Add throws typemaps for std:string* and const std::string*.
2023-04-23: olly
[Javascript] #2453 The testsuite and examples now select which
Javascript engine to test based on what was detected by configure.
Previously they'd always test with node you specified a different
engine (e.g. with `ENGINE=jsc` on the make command line). Now you
only need to specify ENGINE if you have more than one engine
installed.
2023-04-23: olly
[Javascript] Turn on C++ output when wrapping for node, like
we already do when wrapping for V8-without-node.
The testsuite was masking this bug by using SWIG options
`-v8 -DBUILDING_NODE_EXTENSION=1` rather than `-node` when testing
with nodejs, while the javascript examples were masking this by
all getting processed with -c++.
This shouldn't be an incompatible change for users, as if you're
wrapping a C API you'd have to be working around the problem before
this change (like our testsuite and examples were), and this change
shouldn't break your workaround - it just makes it unnecessary.
2023-04-21: mmomtchev
[Javascript] Fix naming of internal C++ helper for wrapping
variables for node to use the "getter" naming scheme rather
than the function wrapping one. In practice this didn't actually
cause problems because Node wrappers are always compiled as C++
and the parameters are always different even if the names are
the same.
2023-04-21: olly
[PHP] Support INPUT,INOUT,OUTPUT for std::string&.
By default SWIG/PHP wraps std::string& as a pass-by-reference PHP
string parameter, but sometimes such a parameter is only for input
or only for output, so add support for the named typemaps that other
target languages support.
2023-04-21: degasus
#2519 Fix CanCastAsInteger range check to clear errno first to fix
bogus failures for valid inputs.if errno is set.
2023-04-21: ZackerySpytz
[OCaml] #1439 Fix reference typemaps for std::string
2023-04-21: olly
#2183 Fix #ifdef and #ifndef to work inside a %define. Previously
they were silently ignored in this context (but #if defined already
worked here if you need a workaround which works for older
versions).
2023-04-20: erezgeva
[Go] #2533 Implement argcargv.i library for Go.
2023-04-19: davidcl
[Scilab] Add support for Scilab 2023.x.
Introduce a new `-gatewayxml6` option to generate XML with full
function names.
2023-04-19: mmomtchev
https://sourceforge.net/p/swig/bugs/1163/ #1882 #2525
Fix preprocessor expansion when a macro expands to the name of
another macro which takes parameters from the input following the
original macro expansion.
2023-04-19: wildmaples
[Ruby] #2527 Fix "undefining the allocator of T_DATA" warning seen
with Ruby 3.2.
2023-04-18: davidcl
[Scilab] #894 extract values with ":" for typemap (int* IN, int IN_SIZE)
2023-04-14: olly
[PHP7] Support for PHP7 has been removed. PHP7 security support
ended 2022-11-28 so it doesn't make sense to include support for
it in the SWIG 4.2.x release series.
*** POTENTIAL INCOMPATIBILITY ***
2023-04-05: wsfulton
[Python] #2515 Add support for all STL containers to be constructible from a Python set.
The previous implementation used the Python Sequence Protocol to convert from Python types
to STL containers. The new implementation uses the Python Iterator Protocol instead and
thereby can convert from a Python set too.
2023-03-25: alatina
[Octave] #2512 Add support for Octave 8.1.
2023-03-22: wsfulton
[C#] #2478 Minor enhancements to std::array wrappers in std_array.i.
2023-03-13: wsfulton
Improved error checking when using %template to instantiate templates within
the correct scope.
1. When a template is instantiated via %template and uses the unary scope
operator ::, an error occurs if the instantiation is attempted within a
namespace that does not enclose the instantiated template.
For example, the following will now error as ::test::max is not enclosed within test1:
Error: '::test::max' resolves to 'test::max' and was incorrectly instantiated in
scope 'test1' instead of within scope 'test'.
namespace test1 {
%template(maxchar) ::test::max<char>;
}
2. SWIG previously failed to always detect a template did not exist when using
%template. In particular when instantiating a global template incorrectly within
namespace. The code below now correctly emits an error:
Error: Template 'test5::GlobalVector' undefined.
namespace test5 {
}
template<typename T> struct GlobalVector {};
%template(GVI) test5::GlobalVector<int>;
2023-03-13: wsfulton
Error out if an attempt is made to define a class using the unary scope
operator ::. The following is not legal C++ and now results in an error:
Error: Using the unary scope operator :: in class definition '::Space2::B' is invalid.
namespace Space2 {
struct B;
}
struct ::Space2::B {};
2023-03-08: wsfulton
Fix duplicate const in generated code when template instantiation type is const
and use of template parameter is also explicitly const, such as:
template <typename T> struct Conster {
void cccc1(T const& t) {}
};
%template(ConsterInt) Conster<const int>;
Above previously led to generated code:
(arg1)->cccc1((int const const &)*arg2);
instead of
(arg1)->cccc1((int const &)*arg2);
2023-03-01: wsfulton
Partial template specialization fixes to support default arguments from the primary
template's parameter list.
template<class Y, class T=int> struct X { void primary() {} };
// Previously the specialization below resulted in:
// Error: Inconsistent argument count in template partial specialization. 1 2
template<class YY> struct X<YY*> { void special(YY*) {} };
// Both of these correctly wrap the partially specialized template
%template(StringPtr) X<const char *>;
%template(ShortPtr) X<short *, int>;
2023-02-15: wsfulton
#1300 Further partial template specialization fixes.
Fixes when templates are used as a template parameter in a partially specialized
instantiation such as:
template<typename V> struct Vect {};
template<class T, typename TT> class Foo { ... };
template<class TS, typename TTS> class Foo<Vect<TS>, TTS> { ... };
%template(VectInt) Vect<int>;
%template(FooVectIntDouble) Foo<Vect<int>, double>; // was previously attempting to use primary template
Also fixes partial specialization where the same template parameter name is used twice,
for example:
template<typename X, typename Y> struct H { ... };
template<typename T> struct H<T, T> { ... };
%template(HInts) H<int, int>; // was previously attempting to use primary template
2023-01-27: jschueller
#2492 [python] Fix unused parameter warnings for self parameter in
generated C/C++ wrapper code.
2023-01-14: wsfulton
Fix deduction of partially specialized template parameters when the specialized
parameter is non-trivial, used in a wrapped method and the type to %template uses
typedefs. For example:
typedef double & DoubleRef;
template <typename T> struct XX {};
template <typename T> struct XX<T &> { void fn(T t) {} };
%template(XXD) XX<DoubleRef>;
The type of the parameter in the instantiated template for fn is now correctly deduced
as double.
2023-01-03: wsfulton
#983 Fix seg fault when instantiating templates with parameters that are function
parameters containing templates, such as:
%template(MyC) C<int(std::vector<int>)>;
2023-01-03: wsfulton
Complete support for C++11 variadic function templates. Support was previously limited
to just one template parameter. Now zero or more template parameters are supported
in the %template instantiation.
2022-12-29: wsfulton
#1863 Syntax error fixes parsing more elaborate parameter pack arguments that are
used in function pointers, member function pointers:
template <typename... V> struct VariadicParms {
void ParmsFuncPtrPtr(int (*)(V*...)) {}
void ParmsFuncPtrPtrRef(int (*)(V*&...)) {}
void ParmsFuncPtrPtrRValueRef(int (*)(V*&&...)) {}
void ParmsFuncPtrRef(int (*)(V&...)) {}
void ParmsFuncPtrRValueRef(int (*)(V&&...)) {}
void ParmsMemFuncPtrPtr(int (KlassMemFuncs::*)(V*...)) {}
void ParmsMemFuncPtrPtrRef(int (KlassMemFuncs::*)(V*&...)) {}
void ParmsMemFuncPtrPtrRValueRef(int (KlassMemFuncs::*)(V*&&...)) {}
void ParmsMemFuncPtrRef(int (KlassMemFuncs::*)(V&...)) {}
void ParmsMemFuncPtrRValueRef(int (KlassMemFuncs::*)(V&&...)) {}
};
%template(VariadicParms0) VariadicParms<>;
%template(VariadicParms1) VariadicParms<A>;
Also in various other places such as within noexcept specifiers:
template<typename T, typename... Args>
void emplace(Args &&... args) noexcept(
std::is_nothrow_constructible<T, Args &&...>::value);
2022-12-27: wsfulton
Fix instantiation of variadic class templates containing parameter pack arguments that
are function pointers.
template <typename... V> struct VariadicParms {
void ParmsFuncPtrVal(int (*)(V...)) {}
};
%template(VariadicParms0) VariadicParms<>;
%template(VariadicParms1) VariadicParms<A>;
2022-12-23: wsfulton
#1863 Fix syntax error parsing variadic templates containing parameter pack arguments that
are function pointers.
2022-12-22: wsfulton
Complete support for C++11 variadic class templates. Support was previously limited
to just one template parameter. Now zero or more template parameters are supported.
2022-12-06: wsfulton
#1636 Fix syntax error for misplaced Doxygen comment after struct/class member.
Fix syntax error using Doxygen member groups syntax, "///*}", when used after
final struct/class member.
2022-12-05: wsfulton
#2023 Fix garbled Doxygen post comments in parameter lists.
Fix syntax error parsing a trailing Doxygen comment in parameter lists.
2022-12-03: wsfulton
#1609 Fix syntax error parsing of Doxygen comments after last enum item.
2022-12-03: wsfulton
#1715 Fix syntax error parsing of unconventionally placed Doxygen post
comments for enum items.
2022-12-02: wsfulton
#624 #1021 Improved template template parameters support. Previously, specifying more
than one simple template template parameter resulted in a parse error. Now
multiple template template parameters are working including instantiation with
%template. Example:
template <template<template<class> class, class> class Op, template<class> class X, class Y>
class C { ... };
2022-11-26: wsfulton
#1589 #1590 Slightly better decltype() support for expressions, such as:
int i;
... decltype(&i) ...
These result in a warning for non-trivial expressions which SWIG cannot evaluate:
Warning 344: Unable to deduce decltype for '&i'.
See 'Type Inference' in CPlusPlus.html for workarounds.
2022-11-22: wsfulton
#366 #1037 Fix seg fault handling template parameter expressions
containing '<=' or '>='.
2022-11-18: wsfulton
Duplicate class template instantiations via %template now issue a warning and are ignored.
%template(Aint) A<int>;
%template(Aint2) A<int>; // Now ignored and issues a warning
example.i:7: Warning 404: Duplicate template instantiation of 'A< int >' with name 'Aint2' ignored,
example.i:6: Warning 404: previous instantiation of 'A< int >' with name 'Aint'.
A single empty template instantiation before a named instantiation is the one exception
for allowing duplicate template instantiations as the empty template instantiation does not
create a wrapper for the template, it merely adds the instantiation into SWIG's internal
type system.
Duplicate empty template instantiations are quietly ignored.
%template() B<int>;
%template(Bint) B<int>; // OK
%template() C<int>;
%template() C<int>; // Quietly ignored now
%template(Cint) C<int>; // OK
Note that default template parameters are considered when looking for duplicates such as:
template <typename T, typename U = short> struct D {};
%template(Dint) D<int>;
%template(Dintshort) D<int, short>;
example.i:7: Warning 404: Duplicate template instantiation of 'D< int,short >' with name 'Dintshort' ignored,
example.i:6: Warning 404: previous instantiation of 'D< int >' with name 'Dint'.
Note that the following always was ignored, but that was because the chosen name was a
duplicate rather than the template being a duplicate:
%template(Eint) E<int>;
%template(Eint) E<int>; // Always has been ignored as a redefined identifier
The old warning was:
example.i:7: Warning 302: Identifier 'Eint' redefined (ignored) (Renamed from 'E< int >'),
example.i:6: Warning 302: previous definition of 'Eint' (Renamed from 'E< int >').
