SVN::Delta - Subversion delta functions
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
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.
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.
If you want to implement an editor, subclass SVN::Delta::Editor and implement the editors callbacks. see the METHODS section below.
Link to the native editor
You can also pass a hash array to new:
Turn on debug.
An arrayref of the editor/baton pair or another SVN::Delta::Editor object to link with.
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.
Functions returning editor/baton pair should really be typemapped to a SVN::Delta::Editor object.
