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, $path,
SVN::Delta::Editor->new(_debug=>1),
1, 1, 0, 1
DESCRIPTIONSVN::Delta wraps delta related function in subversion. The most impor‐
tant one is SVN::Delta::Editor, the interface for describing tree
deltas. by default SVN::Delta::Editor relays method calls to its inter‐
nal member "_editor", which could either be an editor in C (such as the
one you get from get_commit_editor), or another SVN::Delta::Editor
object.
SVN::Delta::Editor
Driving Editors
If you want to drive a native editor (such as commit_editor obtained by
SVN::Repos::get_commit_editor), create a SVN::Delta::Editor object with
the native editor/baton pair. The object will then be ready to use and
its method calls will be relayed to the native editor.
Implementing Editors
If you want to implement an editor, subclass SVN::Delta::Editor and
implement the editors callbacks. see the METHODS section below.
CONSTRUCTOR - new (...)
new ($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.
