STATUS OF THE SWIG BINDINGS

* Python

  The Python bindings are fairly well developed, although there are some
  missing parts, most notably, there is no useful wrapping of the svn_ra APIs.

* 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, and are only partially
  implemented. The Ruby bindings API may change incompatibly as development
  proceeds. They require SWIG 1.3.24 or later.


BUILDING SWIG BINDINGS FOR SVN ON UNIX


Step 1:  Install a suitable version of SWIG (which is
         currently swig versions 1.3.19 - 1.3.21, or 1.3.24 or above).

    * 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 2.0 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.

        For SWIG 1.3.24 or above:
          Run 'make && make install'

        For SWIG 1.3.19 - 1.3.21:
          Run 'make && make runtime && make install && make install-runtime'

    * To verify you have SWIG installed correctly, check that these things
      were created, assuming your $PREFIX was /usr/local:

        For SWIG 1.3.24 or above:
          - /usr/local/bin/swig
          - /usr/local/share/swig/1.3.xx/ (containing lots of .i files)

        For SWIG 1.3.19 - 1.3.21:
          - /usr/local/bin/swig
          - /usr/local/lib/swig1.3/ (containing lots of .i files)
          - /usr/local/lib/libswigpy.so (for Python)
          - /usr/local/lib/libswigpl.so (for Perl)

          In particular, you want to make sure that
          libswigpy.so (if you want to use Python) and/or
          libswigpl.so (if you want to use Perl) was/were built and installed.


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 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'.

   3.  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'


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/

   3.  Configure Visual C++ with paths to swig.exe and language specific
       libraries. 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:

               Path to swig.exe
               (for example, C:\Program Files\SWIG-1.3.19)

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

           Library Directories:

               For Python, path to python##.lib
               (for example, C:\Program Files\Python22\libs)

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

           Include Directories:

               For Python, path to Python.h
               (for example, C:\Program Files\Python22\include)

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

   4.  If you haven't already built Subversion, you should do so now.
       Instructions are in the main INSTALL file. At the very least,
       you need to run gen-make.py to generate Visual Studio project
       files.

   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

   1.  Verify that an 'svn' package has been installed correctly.  You can
       do this by running Python via 'python -c "from svn import client"'.

   2.  Try some demo programs.  From the top of your svn working copy,
       cd tools/examples/ and try running 'svnlook.py'.

   3.  Start writing your own scripts. Use the Subversion API definitions
       and descriptions in:

           subversion/include/svn_client.h
           subversion/include/svn_delta.h
           subversion/include/svn_fs.h
           subversion/include/svn_ra.h
           subversion/include/svn_repos.h
           subversion/include/svn_wc.h

*  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.
