SWIG (Simplified Wrapper and Interface Generator)

Version: 1.3.7 (September 3, 2001)

$Header$

Tagline: SWIG is a compiler that integrates C and C++ with
         languages including Perl, Python, Tcl, Guile, Mzscheme,
         Java and Ruby.

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.

This distribution represents the new stable release of SWIG, aiming to
replace versions 1.1p5 and 1.1-883. The guilty parties working on this
are:

 Dave Beazley (beazley@cs.uchicago.edu)                 (SWIG core)
 William Fulton (wsf@fultondesigns.co.uk)               (Java)
 Matthias Köppe (mkoeppe@mail.math.uni-magdeburg.de)    (Guile/MzScheme)
 Loic Dachary (loic@ceic.com)                           (Perl5)
 Thien-Thi Nguyen (ttn@glug.org)                        (Testing/Misc)
 Masaki Fukushima (fukusima@goto.info.waseda.ac.jp)     (Ruby)

Past contributors (see the CHANGES file for a complete list):

Clark McGrew, Dustin Mitchell, Ian Cooke, Catalin Dumitrescu, Baran
Kovuk, Gary Holt, David Fletcher, Oleg Tolmatcev, Harco de Hilster.

What's New?
===========
Here are the most notable changes (so far):

   - Support for C++ templates.

   - Improvement support for overloaded functions/methods.

   - Parsing support for virtually all C/C++ datatypes.

   - Pointers to members are now supported in the parser
     and by the Python module.

   - Improved support for pointers to functions and callbacks.

   - SWIG now has a full C preprocessor.

   - Code generation for the Tcl and Python modules has been
     substantially improved both in terms of size and runtime
     efficiency (Perl5 is coming along too).

   - The Guile module is stable. It represents C pointers as smobs and
     supports the Guile module system and exceptions.

   - Java, Ruby, and MzScheme modules added.

   - Testing framework part of the distribution ("make -k check" support).

   - A lot of minor bug fixes and cleanup.

   - SWIG requires an ANSI C compiler.

   - Better Windows support.

Here are a few missing features:

   - The SWIG1.1 documentation system is gone and hasn't been
     replaced yet.  This is on the long-term to-do list.

   - The Tcl7.x and Perl4 modules are deprecated and no longer
     included.

   - The Perl5 module is need in some repair.  We are looking for
     a maintainer to help us with this.

   - A wide variety of old SWIG command-line options and
     obscure features are gone.

   - Objective C support doesn't work right now.  No ETA as to
     when it will return.

Although we are making every attempt preserve backwards compatibility
with interfaces written for SWIG1.1, SWIG1.3 incorporates a number of
very substantial modifications to things such as type handling,
typemaps, and wrapper code generation.  Therefore, if you are making
extensive use of advanced SWIG features, interfaces written for
SWIG1.1 may not work.  We apologize for the inconvenience, but these
changes are needed in order to fix a number of annoying "features"
in SWIG1.1.

In addition, SWIG1.3 makes no attempt to be compatible with SWIG1.1 at
the C++ API level so language modules written for SWIG1.1 will most
definitely not work with this release.

The files NEW and CHANGES describe in some detail all of the important
changes that have been made to the system.  Experienced users would be
well advised to read this.

Windows
=======
Please see the Win/Windows.html file for instructions on obtaining 
and using SWIG on Windows.

Unix Installation
=================
To build and install SWIG, simply type the following:

     % ./configure
     % make
     % make -k check	# this step is optional (see note below)
     % make install

The file INSTALL details more about using configure. Also try

     % ./configure --help. 

The configure script will attempt to locate various packages on your 
machine, including Tcl, Perl5, Python and other target languages that SWIG 
uses.  Don't panic if you get 'not found' messages--SWIG does not need these 
packages to compile or run.   The configure script is actually looking for 
these packages so that you can try out the SWIG examples contained
in the 'Examples' directory without having to hack Makefiles.

Notes:

(1) If you checked the code out via CVS, you will have to run ./autogen.sh
    before typing 'configure'.    In addition, a full build of SWIG requires
    the use of bison.

(3) 'make -k check' is a new feature that requires at least one of the target
    languages to be installed and which performs compile/link level testing
    of the examples.  If it fails, it may mean that you have an uninstalled
    language module or that the file 'Examples/Makefile' has been
    incorrectly configured.  It may also fail due to compiler issues 
    such as broken C++ compiler.  Even if 'make -k check' fails, there is a 
    pretty good chance SWIG still works correctly---you will just have
    to mess around with one of the examples and some makefiles first.

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 now includes Visual C++ project files for
building some of the examples on Windows (new in SWIG1.3.7).

Documentation
=============
The Doc/Manual directory contains the most recent set of updated
documentation for this release.  As this is an unstable development
release, the documentation is not quite up to date and is being worked
on.  We are working on it, but there is a lot of documentation and it
is going to take time to complete. Please be patient.

! The most up-to-date information concerning new features in SWIG1.3 is the
! file Doc/Manual/SWIG.html.

There is some technical documentation available in the Doc/Devel 
subdirectory.  This is not necessarily up-to-date, but it has some
information on SWIG internals.

Participate!
============

Please report any errors and submit patches (if possible)!  We only
have access to a limited variety of hardware (Linux, Solaris, 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 beazley@cs.uchicago.edu.
