NAME

       SVN::Delta - Subversion delta functions

SYNOPSIS

	   require SVN::Core;
	   require SVN::Repos;
	   require SVN::Delta;

	   # driving an editor
	   my $editor = SVN::Delta::Editor->
	       new(SVN::Repos::get_commit_editor($repos, "file://$repospath",
						 '/', 'root', 'FOO', &committed));

	   my $rootbaton = $editor->open_root(0);

	   my $fbaton = $editor->add_file ('filea', $rootbaton,
					   undef, -1);

	   my $ret = $editor->apply_textdelta ($fbaton, undef);
	   SVN::TxDelta::send_string("FILEA CONTENT", @$ret);

	   # implement an editor in perl
	   SVN::Repos::dir_delta($root1, $path, undef,
				 $root2, $path,
				 SVN::Delta::Editor->new(_debug=>1),
				 1, 1, 0, 1

DESCRIPTION

       SVN::Delta wraps delta related function in subversion. The most important one is SVN::Delta::Editor, the interface for describing tree
       deltas. by default SVN::Delta::Editor relays method calls to its internal member "_editor", which could either be an editor in C (such as
       the one you get from get_commit_editor), or another SVN::Delta::Editor object.

SVN
::Delta::Editor
   Driving Editors
       If you want to drive a native editor (such as commit_editor obtained by SVN::Repos::get_commit_editor), create a SVN::Delta::Editor object
       with the native editor/baton pair. The object will then be ready to use and its method calls will be relayed to the native editor.

   Implementing Editors
       If you want to implement an editor, subclass SVN::Delta::Editor and implement the editors callbacks. see the METHODS section below.

   CONSTRUCTOR - new (...)
       new ($editor, $editor_baton)
	   Link to the native editor

       You can also pass a hash array to new:

       _debug
	   Turn on debug.

       _editor
	   An arrayref of the editor/baton pair or another SVN::Delta::Editor object to link with.

   METHODS
       Please consult the svn_delta.h section in the Subversion API. Member functions of svn_delta_editor_t could be called as methods of
       SVN::Delta::Editor objects, with the edit_baton omitted. The pool is also optional.

       If you are subclassing, the methods take exactly the same arguments as the member functions (note that void ** are returned data though as
       throughout the perl bindings), with the edit_baton omitted.

BUGS

       Functions returning editor/baton pair should really be typemapped to a SVN::Delta::Editor object.

NAME

       SVN::Base - Base class for importing symbols for svn modules

SYNOPSIS

	   # Load the svn_ra_* functions into the SVN::Ra namespace.
	   package SVN::Ra;
	   use SVN::Base qw(Ra svn_ra_);

	   # Load svn_config_t structure accessors in the magic namcespace
	   # provided by swig, so we could use it returned by other functions
	   package _p_svn_config_t;
	   use SVN::Base qw(Core svn_config_);

DESCRIPTION

       SVN::Base is a module importing the subversion perl bindings raw symbols created by swig, into proper namespace and make them easier to
       use.

       It will also find the accessors for members of a C struct, create an simpler accessor function like "$data->field()" and
       "$data->field($new_value)".

       Once you understand the convention of subversion functions in perl bindings, you could look at the subversion api and write them in perl.
       The API is available in the source header files or online at http://svn.collab.net/svn-doxygen/.

INTERNALS

       The perl bindings of swig wraps raw functions into different perl modules, for example, SVN::_Core, SVN::_Repos. Upon import, SVN::Base
       bootstrap the requested module if it's not yet loaded, and iterate over the symbols provided in that module, it them puts the function with
       prefix trimmed in the namespace of the caller for this import.

       The 3rd through the last parameter is a list of symbol endings that you wish for SVN::Base not to import into your namespace.  This is
       useful for cases where you may want to import certaion symbols differently than normally.

CAVEATS

       SVN::Base consider a function as structure member accessor if it is postfixed ``_get'' or ``_set''. Real functions with this postfixes will
       need extra handling.
