SWIG (Simplified Wrapper and Interface Generator) Version: 3.0.0 (16 Mar 2014) 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, CHICKEN), Ocaml, Modula-3, Common Lisp (CLISP, Allegro CL, CFFI, UFFI) and Pike. SWIG can also export its parse tree into Lisp s-expressions and 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 http://www.swig.org A SWIG FAQ and other hints can be found on the SWIG Wiki: http://www.dabeaz.com/cgi-bin/wiki.pl 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 http://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 http://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. The INSTALL file has generic build and installation instructions for Unix users. 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 http://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 http://www.dabeaz.com/cgi-bin/wiki.pl. 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 http://www.swig.org/mail.html. -- The SWIG Maintainers Below are the changes for the current release. See the CHANGES file for changes in older releases. See the RELEASENOTES file for a summary of changes in each release. Version 3.0.0 (16 Mar 2014) =========================== 2014-03-16: wsfulton C++11 support initially developed as C++0x support by Matevz Jekovec as a Google Summer of Code project has been further extended. The C++11 support is comprehensive, but by no means complete or without limitations. Full details for each new feature in C++11 is covered in the CPlusPlus11.html chapter in the documentation which is included in SWIG and also available online at http://www.swig.org/Doc3.0/CPlusPlus11.html. 2014-03-14: v-for-vandal [Lua] Numerous Lua improvements: 1. %nspace support has been added. Namespaces are mapped to tables in the module, with the same name as the C++ namespace. 2. Inheritance is now handled differently. Each class metatable keeps a list of class bases instead of merging all members of all bases into the derived class. 3. The new metatables result in differences in accessing class members. For example: %module example struct Test { enum { TEST1 = 10, TEST2 = 20 }; static const int ICONST = 12; }; Now this can be used as follows: print(example.Test.TEST1) print(example.Test.ICONST) The old way was: print(example.Test_TEST1) print(example.Test_ICONST) 4. The special class metatable member ".constructor" was removed. Now SWIG generates the proxy function by itself and assigns it directly to the class table "__call" method. 5. eLua should also now support inheritance. 6. 'const' subtable in eLua is considered deprecated. Changes in behaviour: a. You can no longer assign to non-existing class members in classes without a __setitem__ method. It will cause a Lua error. b. You can no longer iterate over a module table and copy everything into the global namespace. Actually, this was never the case, but it is now explicitly prohibited. c. Now changing a base class will immediately affect all derived classes. d. There might be some issues with inheritance. Although the bases iteration scheme is the same as was used for merging base classes into derived one, some unknown issues may arise. The old metatable behaviour can be restored by using the -no-old-metatable-bindings option. *** POTENTIAL INCOMPATIBILITY *** 2014-03-06: wsfulton [Python] Change in default behaviour wrapping C++ bool. Only a Python True or False will now work for C++ bool parameters. This fixes overloading bool with other types. Python 2.3 minimum is now required for wrapping bool. When wrapping: const char* overloaded(bool value) { return "bool"; } const char* overloaded(int value) { return "int"; } Previous behaviour: >>> overloaded(False) 'int' >>> overloaded(True) 'int' >>> overloaded(0) 'int' Now we get the expected behaviour: >>> overloaded(False) 'bool' >>> overloaded(0) 'int' The consequence is when wrapping bool in non-overloaded functions: const char* boolfunction(bool value) { return value ? "true" : "false"; } The previous behaviour was very Pythonic: >>> boolfunction("") 'false' >>> boolfunction("hi") 'true' >>> boolfunction(12.34) 'true' >>> boolfunction(0) 'false' >>> boolfunction(1) 'true' Now the new behaviour more along the lines of C++ due to stricter type checking. The above calls result in an exception and need to be explicitly converted into a bool as follows: >>> boolfunction(0) Traceback (most recent call last): File "", line 1, in TypeError: in method 'boolfunction', argument 1 of type 'bool' >>> boolfunction(bool(0)) 'false' The old behaviour can be resurrected by passing the -DSWIG_PYTHON_LEGACY_BOOL command line parameter when executing SWIG. Typemaps can of course be written to customise the behaviour for specific parameters. *** POTENTIAL INCOMPATIBILITY *** 2014-03-06: wsfulton Fix SF Bug #1363 - Problem with method overloading when some methods are added by %extend and others are real methods and using template default parameters with smart pointers. This is noticeable as a regression since 2.0.12 when using the default smart pointer handling for some languages when the smart pointer wraps std::map and other STL containers. 2014-03-02: wsfulton [Python] SF Patch #346 from Jens Krueger. Correct exception thrown attempting to access a non-existent C/C++ global variable on the 'cvar' object. The exception thrown used to be a NameError. However, as this access is via a primary, an AttributeError is more correct and so the exception thrown now is an AttributeError. Reference: http://docs.python.org/2/reference/expressions.html#attribute-references *** POTENTIAL INCOMPATIBILITY *** 2014-03-01: wsfulton [Python] Patch #143 Fix type shown when using type() to include the module and package name when using -builtin. 2014-03-01: wsfulton [Python] SF patch #347 Fix missing argument count checking with -modern. Fixes regression introduced when builtin changes were introduced in SWIG-2.0.3. 2014-02-21: wsfulton [PHP] Fix warning suppression using %warnfilter for PHP reserved class names. 2014-02-19: olly [Lua] Add keyword warnings for Lua keywords and Basic Functions. 2014-02-19: olly -Wallkw now includes keywords for all languages with keyword warnings (previously Go and R were missing). 2014-02-19: olly [PHP] Update the lists of PHP keywords with new ones from PHP 5.4 and newer (and some missing ones from 5.3). Reserved PHP constants names are now checked against enum values and constants, instead of against function and method names. Built-in PHP function names no longer match methods added by %extend. Functions and methods named '__sleep', '__wakeup', 'not', 'parent', or 'virtual' are no longer needlessly renamed. 2014-02-15: wsfulton Fix the %$ismember %rename predicates to also apply to members added via %extend. Add %$isextendmember for %rename of members added via %extend. This can be used to distinguish between normal class/struct members and %extend members. For example '%$ismember, %$not %$isextendmember' will now identify just class/struct members. *** POTENTIAL INCOMPATIBILITY *** 2014-02-16: hfalcic [Python] Patch #137 - fix crashes/exceptions in exception handling in Python 3.3 2014-02-15: wsfulton [Java] Add support for the cdata library. 2014-02-08: vkalinin Nested class support added. This primarily allows SWIG to properly parse nested classes and keep the nested class information in the parse tree. Java and C# have utilised this information wrapping the C++ nested classes as Java/C# nested classes. The remaining target languages ignore nested classes as in previous versions. Help is needed by users of these remaining languages to design how C++ nested classes can be best wrapped. Please talk to us on the swig-devel mailing list if you think you can help. Previously, there was limited nested class support. Nested classes were treated as opaque pointers. However, the "nestedworkaround" feature provided a way to wrap a nested class as if it was a global class. This feature no longer exists and is replaced by the new "flatnested" feature. This effectively does the same thing with less manual code to be written. Please see the 'Nested classes' section in the documentation in SWIGPlus.html if you were previously using this feature. SWIG now parses the contents of nested classes where previously it did not. You may find that you will need to make adjustments to your interface file as effectively extra code is being wrapped. *** POTENTIAL INCOMPATIBILITY *** 2014-02-06: gjanssens [Guile] Patch #133. Make scm to string conversion work with non-ascii strings. Guile 2 has a completely rewritten string implementation. SWIG made some assumptions that are no longer valid as to the internals of guile's string representation. 2014-01-30: wsfulton [C#] Add new swigtype_inout.i library containing SWIGTYPE *& OUTPUT typemaps. Example usage wrapping: void f(XXX *& x) { x = new XXX(111); } would be: XXX x = null; f(out x); // use x x.Dispose(); // manually clear memory or otherwise leave out and leave it to the garbage collector 2014-01-21: ianlancetaylor [Go] Add %go_import directive. 2014-01-21: ianlancetaylor [Go] Add support for Go 1.3, not yet released. 2014-01-20: wsfulton Director exceptions (Swig::DirectorException) now derive from std::exception and hence provide the what() method. In Python and Ruby, this replaces the now deprecated DirectorException::getMessage() method. 2014-01-14: diorcety Patch #112 - Fix symbol resolution involving scopes that have multiple levels of typedefs - fixes some template resolutions as well as some typemap searches. 2014-01-11: wsfulton Fix and document the naturalvar feature override behaviour - the naturalvar feature attached to a variable name has precedence over the naturalvar feature attached to the variable's type. The overriding was not working when turning the feature off on the variable's name. Fix so that any use of the naturalvar feature will override the global setting. Previously when set globally by -naturalvar or %module(naturalvar=1), use of the naturalvar feature was not always honoured. 2014-01-06: ianlancetaylor [Go] Fix bug that broke using directors from a thread not created by Go. 2013-12-24: ptomulik [Python] SF Bug #1297 Resolve several issues related to python imports. For example, it's now possible to import modules having the same module names, but belonging in different packages. From the user's viewpoint, this patch gives a little bit more control on import statements generated by SWIG. The user may choose to use relative or absolute imports. Some details: - we (still) generate import statements in the form 'import a.b.c' which corresponds to absolute imports in python3 and (the only available) ambiguous one in python2. - added -relativeimport option to use explicit relative import syntax (python3), The "Python Packages" section in the documentation discusses how to work with importing packages including the new -relativeimport command line option. 2013-12-23: vadz [Octave, Perl, Python, R, Ruby, Tcl] Change the length of strings created from fixed-size char buffers in C code. This is a potential backwards compatibility break: a "char buf[5]" containing "ho\0la" was returned as a string of length 5 before, but is returned as a string of length 2 now. Also, it was possible to assign a (non-NUL-terminated) string "hello" to such a buffer before but now this fails and only "helo" can fit. Apply "char FIXSIZE[ANY]" typemaps to explicitly choose the old behaviour. *** POTENTIAL INCOMPATIBILITY *** 2013-12-23: talby [Perl] Add support for directors. 2013-12-18: ianlancetaylor [Go] Don't require that Go environment variables be set when running examples or testsuite when using Go 1 or later. 2013-12-17: ianlancetaylor [Go] Remove -longsize option (for backward compatibility, ignore it if seen). 2013-12-17: ianlancetaylor [Go] Add -go-pkgpath option. 2013-12-16: ianlancetaylor [Go] Update for Go 1.2 release. Add support for linking SWIG code directly into executable, rather than using a shared library. 2013-12-13: ianlancetaylor [Go] Add SWIG source file name as comments in generated files. This can be used by Go documentation tools. 2013-12-12: jleveque [Lua] Fix typo (wchar instead of wchar_t) which made wchar.i for Lua useless. 2013-12-12: vmiklos [PHP] PHP's peculiar call-time pass-by-reference feature was deprecated in PHP 5.3 and removed in PHP 5.4, so update the REF typemaps in phppointers.i to specify pass-by-reference in the function definition. Examples/php/pointer has been updated accordingly. 2013-12-12: olly [PHP] The usage of $input in PHP directorout typemaps has been changed to be consistent with other languages. The typemaps provided by SWIG have been updated accordingly, but if you have written your own directorout typemaps, you'll need to update $input to &$input (or make equivalent changes). *** POTENTIAL INCOMPATIBILITY *** 2013-11-27: vadz [C#, Java, Python] Add std_auto_ptr.i defining typemaps for returning std::auto_ptr<>. 2013-11-09: wsfulton [C#] Apply patch #79 from Brant Kyser - Remove using directives from the generated C# code and fully qualify the use of all .NET framework types in order to minimize potential name collisions from input files defining types, namespace, etc with the same name as .NET framework members. - Globally qualify the use of .NET framework types in the System namespace - Remove .NET 1.1 support, .NET 2 is the minimum for the C# module This is a potential backwards compatibility break if code has been added relying on these using statements that used to be generated: using System; using System.Runtime.InteropServices; The quick fix to add these back in is to add the -DSWIG2_CSHARP command line option when executing SWIG. See CSharp.html documentation for more info. *** POTENTIAL INCOMPATIBILITY *** 2013-11-05: wsfulton [Java] Fix some corner cases for the $packagepath/$javaclassname special variable substitution. 2013-11-05: wsfulton [Java] Apply patch #91 from Marvin Greenberg - Add director:except feature for improved exception handling in director methods for Java. 2013-10-15: vadz Allow using \l, \L, \u, \U and \E in the substitution part of %(regex:/pattern/subst/) inside %rename to change the case of the text being replaced. 2013-10-12: wsfulton [CFFI] Apply #96 - superclass not lispify 2013-10-12: wsfulton Merge in C++11 support from the gsoc2009-matevz branch where Matevz Jekovec first started the C++0x additions. Documentation of the C++11 features supported is in a new Chapter of the documentation, "SWIG and C++11" in Doc/Manual/CPlusPlus11.html. 2013-10-04: wsfulton Fix %naturalvar not having any affect on templated classes instantiated with an enum as the template parameter type. Problem reported by Vadim Zeitlin. 2013-09-20: wsfulton [Java] Fix a memory leak for the java char **STRING_ARRAY typemaps. This file contains a brief overview of the changes made in each release. A detailed description of changes are available in the CHANGES.current and CHANGES files.

We discourage the use of the 'nodefault' option, which disables both constructors and destructors, leading to possible memory leaks. Use instead 'nodefaultctor' and/or 'nodefaultdtor'. - Automatic copy constructor wrapper generation via the 'copyctor' option/feature. - Better handling of Windows extensions and types. - Better runtime error reporting. - Add the %catches directive to catch and dispatch exceptions. - Add the %naturalvar directive for more 'natural' variable wrapping. - Better default handling of std::string variables using the %naturalvar directive. - Add the %allowexcept and %exceptionvar directives to handle exceptions when accessing a variable. - Add the %delobject directive to mark methods that act like destructors. - Add the -fastdispatch option to enable smaller and faster overload dispatch mechanism. - Template support for %rename, %feature and %typemap improved. - Add/doc more debug options, such as -dump_module, -debug_typemaps, etc. - Unified typemap library (UTL) potentially providing core typemaps for all scripting languages based on the recently evolving Python typemaps. - New language module: Common Lisp with CFFI. - Python, Ruby, Perl and Tcl use the new UTL, many old reported and hidden errors with typemaps are now fixed. - Initial Java support for languages using the UTL via GCJ, you can now use Java libraries in your favorite script language using gcj + swig. - Tcl support for std::wstring. - PHP4 module update, many error fixes and actively maintained again. - Allegrocl support for C++, also enhanced C support. - Ruby support for bang methods. - Ruby support for user classes as native exceptions. - Perl improved dispatching in overloaded functions via the new cast and rank mechanism. - Perl improved backward compatibility, 5.004 and later tested and working. - Python improved backward compatibility, 1.5.2 and later tested and working. - Python can use the same cast/rank mechanism via the -castmode option. - Python implicit conversion mechanism similar to C++, via the %implicitconv directive (replaces and improves the implicit.i library). - Python threading support added. - Python STL support improved, iterators are supported and STL containers can use now the native PyObject type. - Python many performance options and improvements, try the -O option to test all of them. Python runtime benchmarks show up to 20 times better performance compared to 1.3.27 and older versions. - Python support for 'multi-inheritance' on the python side. - Python simplified proxy classes, now swig doesn't need to generate the additional 'ClassPtr' classes. - Python extended support for smart pointers. - Python better support for static member variables. - Python backward compatibility improved, many projects that used to work only with swig-1.3.21 to swig-1.3.24 are working again with swig-1.3.28 - Python test-suite is now 'valgrinded' before release, and swig also reports memory leaks due to missing destructors. - Minor bug fixes and improvements to the Lua, Ruby, Java, C#, Python, Guile, Chicken, Tcl and Perl modules. SWIG-1.3.27 summary: - Fix bug in anonymous typedef structures which was leading to strange behaviour SWIG-1.3.26 summary: - New language modules: Lua, CLISP and Common Lisp with UFFI. - Big overhaul to the PHP module. - Change to the way 'extern' is handled. - Minor bug fixes specific to C#, Java, Modula3, Ocaml, Allegro CL, XML, Lisp s-expressions, Tcl, Ruby and Python modules. - Other minor improvements and bug fixes. SWIG-1.3.25 summary: - Improved runtime type system. Speed of module loading improved in modules with lots of types. SWIG_RUNTIME_VERSION has been increased from 1 to 2, but the API is exactly the same; only internal changes were made. - The languages that use the runtime type system now support external access to the runtime type system. - Various improvements with typemaps and template handling. - Fewer warnings in generated code. - Improved colour documentation. - Many C# module improvements (exception handling, prevention of early garbage collection, C# attributes support added, more flexible type marshalling/asymmetric types.) - Minor improvements and bug fixes specific to the C#, Java, TCL, Guile, Chicken, MzScheme, Perl, Php, Python, Ruby and Ocaml modules). - Various other bug fixes and memory leak fixes.
