STATUS OF THE SWIG BINDINGS

* Python

  The Python bindings are fairly well developed, although there are some
  missing parts.

  (N.B. As discussed below, they will not compile in Debug mode on Windows.)

* Perl

  The Perl bindings are complete, with the exception of SVN::Wc, on which
  very little work has been done.

* Ruby

  The Ruby bindings are a recent development, but are fully implemented.
  The Ruby bindings API may change incompatibly as development proceeds.

  Completed modules:
  - Svn::Client
  - Svn::Core::Config
  - Svn::Delta

BUILDING SWIG BINDINGS FOR SVN ON UNIX


Step 1:  Install a suitable version of SWIG (which is
         currently swig version 1.3.24 - 1.3.31).

    * Perhaps your distribution packages a suitable version - if it does
      install it, and skip to the last bullet point in this section.

    * Go to http://www.swig.org/, download the source tarball, and unpack.

    * In the SWIG-1.3.xx directory, run ./configure.

        If you plan to build the Python bindings, and have a system
        with more than one version of Python installed, you may need
        to pass

             --with-python=/path/to/correct/python/binary

        to the configure script.  You need Python 2.2 or above.

        If you plan to build the Perl bindings, and have a system
        with more than one version of perl installed, you may need
        to pass

             --with-perl5=/path/to/correct/perl/binary

        to the configure script.  You need Perl 5.8.0 or above.

    * Build and install.

        Run 'make && make install'

    * To verify you have SWIG installed correctly, run "swig -version"
      from the command line. SWIG should report that it is version 1.3.24
      or newer.

Step 2:  Build and Install Subversion.

  See Subversion's own INSTALL file for details.

  Make sure that Subversion's ./configure script sees your installed SWIG!
  It tries to detect SWIG near the very end of its output.

  Also make sure that the configure script sees the paths to the perl and/or
  python executable you used to configure SWIG as above.  If it does not then
  you can specify the correct path by adding PYTHON=/path/to/python or
  PERL=/path/to/perl onto the command line for configure.  For example:
       ./configure PYTHON=/usr/bin/python2.2 PERL=/usr/bin/perl5.8.0

  If Subversion's ./configure finds a SWIG that it's happy with, then
  it will build special glue libraries to link svn to the swig bindings:
    libsvn_swig_py.so (for Python)
    libsvn_swig_perl.so (for Perl)


Step 3:  Install Specific Language Bindings

*  Python

   1.  Run 'make swig-py' from the top of the Subversion source tree,
       to build the bindings.

       (This will invoke SWIG on the *.i files, resulting in a collection
       of .c source files.  It will then compile and link those .c files into
       Python libraries.)

   2.  Run 'make check-swig-py' from the top of the Subversion source
       tree, to test the bindings 

   3.  Run 'make install-swig-py' (as root, typically)
       from the top of the Subversion source tree.  This will copy
       your new Python libraries into the appropriate system location.

       Note: If you don't have access to install to Python's site-packages
       directory, you can have the Python modules install to your home
       directory.  You can do this by running
       'make install-swig-py swig_pydir=~'.

       Note: If you want to install to an alternate prefix (usually only
       if you are building packages), you can supply the prefix here.  An
       example of doing this for building rpms looks like
       'make install-swig-py DESTDIR=$RPM_BUILD_ROOT/usr'.

   4.  Make sure that whatever directory the bindings got installed in
       is in your PYTHONPATH.  That directory depends on how you
       installed; a typical location is /usr/local/lib/svn-python/.

       An nice way to do this is:
       $ echo /usr/local/lib/svn-python \
           > /usr/lib/python2.x/site-packages/subversion.pth


*  Perl

   Perl 5.8.0 is required.  You can specify the perl binary by passing
   PERL=/path/to/perl as part of the configure command in the top level
   of the Subversion source tree.  Make sure that the Perl version used
   is the same one that you configured SWIG to run against during the
   SWIG configure (see above).

   1.  Run `make swig-pl' from the top of the Subversion source tree.

   2.  Run `make check-swig-pl' from the top of the Subversion source
       tree, to test the bindings 

   3.  to install run `make install-swig-pl' from the top of the
       Subversion source tree.

   If you need to pass extra parameters to Perl build process (Makefile.PL),
   then you need to do this process somewhat different:

   1.  Run `make swig-pl-lib' from the top of the Subversion source tree.

   2.  Run `make install-swig-pl-lib'

   3.  cd subversion/bindings/swig/perl/native 

   4.  Run `perl Makefile.PL EXTRAOPTIONSHERE` 

   5.  Run `make install'

   To install the Perl bindings in a location other than the system
   Perl directory, use the above instructions with the extra option
   PREFIX=/your/prefix/here.


* Ruby
  
   1. Run `make swig-rb' from the top of the Subversion source tree,
      to build the bindings.

   2. Run `make check-swig-rb' from the top of the Subversion source
      tree, to test the bindings.

   3. To install, run `make install-swig-rb' from the top of the 
      Subversion source tree.

   You can specify the ruby binary by passing RUBY=/path/to/ruby as part 
   of the configure command in the top level of the Subversion source 
   tree. Make sure that the Ruby version used is the same one that you 
   configured SWIG to run against during the SWIG configure (see above). 
   

BUILDING SWIG BINDINGS FOR SVN ON WINDOWS


   1.  Install SWIG. Download the SWIG Windows zipfile (it's the same as the
       source tarball except that it also includes a copy of swig.exe) from

           http://www.swig.org/

       and extract it somewhere, like C:\Program Files.

   2.  Install whatever languages you want to build runtimes for. Windows
       versions of Python and Perl are available from:

           http://www.python.org/
           http://www.activestate.com/ActivePerl/

       NOTE: Our Python SWIG bindings will currently NOT compile in Debug mode
             unless you have python24_d.lib (which binary distributions of
             Python do not contain).  Therefore, the Python bindings will only
             compile in Release mode.  (This is due to pyconfig.h using the
            _DEBUG flag too and setting a #pragma comment(lib) value.)

       For Perl support, you also need to add the paths into Visual Studio.

       In Visual C++ 6, go to Tools -> Options -> Directories.

       In Visual C++ .NET, go to Tools -> Options -> Projects
       -> VC++ Directories.

       Add the following paths:

           Executable Directories:

               For Perl, path to perl.exe
               (for example, C:\Program Files\Perl\bin)

           Library Directories:

               For Perl, path to perl##.lib
               (for example, C:\Program Files\Perl\lib\CORE)

           Include Directories:

               For Perl, path to perl.h
               (for example, C:\Program Files\Perl\lib\CORE)

   3.  Create the Visual Studio project files via gen-make.py, adding in
       the --with-swig parameter to the installed location for SWIG.
       Example:

        > gen-make.py -t vcproj --with-swig="C:\Program Files\SWIG-1.3.31"

   4.  If you haven't already built Subversion, you should do so now.
       Instructions are in the main INSTALL file.

   5.  Build the bindings. Open the Subversion workspace in Visual C++
       (subversion_msvc.dsw or subversion_vcnet.sln) and build one or more
       of the following projects:

           __SWIG_PYTHON__
           __SWIG_PERL__

   6. Install the bindings. The procedure varies depending on the language.

      For Python, create two folders:

          <PYTHON>\Lib\site-packages\svn
          <PYTHON>\Lib\site-packages\libsvn

      Copy subversion\bindings\swig\python\svn\*.py into the svn folder.
      Copy subversion\bindings\swig\python\*.py and
      Release\subversion\bindings\swig\python\*.dll into the libsvn folder.

      Optionally, you can run the following commands to compile the Python
      sources into bytecode:

          python <PYTHON>\lib\compileall.py <PYTHON>\Lib\site-packages\svn
          python <PYTHON>\lib\compileall.py <PYTHON>\Lib\site-packages\libsvn

      This can make the modules load faster for users without write access
      to the site-packages directory.

      For Perl, the bindings have be copied into a more complicated directory
      structure inside the Perl library directory. Running the commands below
      from the subversion source directory will copy the files to the right
      places:

        set PERL_LIBS="C:\Program Files\Perl\site\lib"

        md %PERL_LIBS%\SVN %PERL_LIBS%\auto\SVN
        copy subversion\bindings\swig\perl\native\*.pm %PERL_LIBS%\SVN

        md %PERL_LIBS%\auto\SVN\_Client
        copy Release\subversion\bindings\swig\perl\_Client.dll %PERL_LIBS%\auto\SVN\_Client
        copy Release\subversion\bindings\swig\perl\_Client.pdb %PERL_LIBS%\auto\SVN\_Client

        md %PERL_LIBS%\auto\SVN\_Core
        copy Release\subversion\bindings\swig\perl\_Core.dll %PERL_LIBS%\auto\SVN\_Core
        copy Release\subversion\bindings\swig\perl\_Core.pdb %PERL_LIBS%\auto\SVN\_Core

        md %PERL_LIBS%\auto\SVN\_Delta
        copy Release\subversion\bindings\swig\perl\_Delta.dll %PERL_LIBS%\auto\SVN\_Delta
        copy Release\subversion\bindings\swig\perl\_Delta.pdb %PERL_LIBS%\auto\SVN\_Delta

        md %PERL_LIBS%\auto\SVN\_Fs
        copy Release\subversion\bindings\swig\perl\_Fs.dll %PERL_LIBS%\auto\SVN\_Fs
        copy Release\subversion\bindings\swig\perl\_Fs.pdb %PERL_LIBS%\auto\SVN\_Fs

        md %PERL_LIBS%\auto\SVN\_Ra
        copy Release\subversion\bindings\swig\perl\_Ra.dll %PERL_LIBS%\auto\SVN\_Ra
        copy Release\subversion\bindings\swig\perl\_Ra.pdb %PERL_LIBS%\auto\SVN\_Ra

        md %PERL_LIBS%\auto\SVN\_Repos
        copy Release\subversion\bindings\swig\perl\_Repos.dll %PERL_LIBS%\auto\SVN\_Repos
        copy Release\subversion\bindings\swig\perl\_Repos.pdb %PERL_LIBS%\auto\SVN\_Repos

        md %PERL_LIBS%\auto\SVN\_Wc
        copy Release\subversion\bindings\swig\perl\_Wc.dll %PERL_LIBS%\auto\SVN\_Wc
        copy Release\subversion\bindings\swig\perl\_Wc.pdb %PERL_LIBS%\auto\SVN\_Wc

TESTING AND USING SWIG BINDINGS

*  Python

   You can exercise the Python bindings test suite by running 'make
   check-swig-py' as described in the install section.

   For examples of how to use the Python bindings, check out the
   sample/demo programs found in tools/examples/ in the Subversion
   source code tree.  Additionally, there are several third-party
   tools that make use of these bindings, including ViewVC
   (http://viewvc.tigris.org/) and Trac (http://trac.edgewall.org/).

*  Perl

   The Perl bindings are using the standard module testing facilities
   to do regression tests. Simply run 'make check-swig-pl' as described in 
   the install section.

* Ruby

   To test the Ruby bindings, simply run `make check-swig-rb' as described 
   in the install section.
   
   For examples of how to use the Ruby bindings, take a look at the .rb files
   in the following directory:
     subversion/bindings/swig/test
