svn::simple::edit
SVN::Simple::Edit(3) User Contributed Perl Documentation SVN::Simple::Edit(3)
NAME
SVN::Simple::Edit - A simple interface for driving svn delta editors
SYNOPSIS
my $edit = SVN::Simple::Edit->new
(_editor => [SVN::Repos::get_commit_editor($repos, "file://$repospath",
'/', 'root', 'FOO', &committed)],
);
$edit->open_root($fs->youngest_rev);
$edit->add_directory ('trunk');
$edit->add_file ('trunk/filea');
$edit->modify_file ("trunk/fileb", "content", $checksum);
$edit->delete_entry ("trunk/filec");
$edit->close_edit ();
...
$edit->copy_directory ('branches/a, trunk, 0);
DESCRIPTION
SVN::Simple::Edit wraps the subversion delta editor with a perl friendly interface and then you could easily drive it for describing
changes to a tree. A common usage is to wrap the commit editor, so you could make commits to a subversion repository easily.
This also means you can not supply the $edit object as an delta_editor to other API, and that's why this module is named ::Edit instead of
::Editor.
See SVN::Simple::Editor for simple interface implementing a delta editor.
PARAMETERS
for constructor
_editor
The editor that will receive delta editor calls.
missing_handler
Called when parent directory are not opened yet, could be:
&SVN::Simple::Edit::build_missing
Always build parents if you don't open them explicitly.
&SVN::Simple::Edit::open_missing
Always open the parents if you don't create them explicitly.
SVN::Simple::Edit::check_missing ([$root])
Check if the path exists on $root. Open it if so, otherwise create it.
root
The default root to use by SVN::Simple::Edit::check_missing.
base_path
The base path the edit object is created to send delta editor calls.
noclose
Do not close files or directories. This might make non-sorted operations on directories/files work.
METHODS
Note: Don't expect all editors will work with operations not sorted in DFS order.
open_root ($base_rev)
add_directory ($path)
open_directory ($path)
copy_directory ($path, $from, $fromrev)
add_file ($path)
open_file ($path)
copy_file ($path, $from, $fromrev)
delete_entry ($path)
change_dir_prop ($path, $propname, $propvalue)
change_file_prop ($path, $propname, $propvalue)
