Edit and compare giant binary files with lfhex

Tue, 27 May 2008 08:00:00 GMT
Many hex editors try to copy an entire file into memory before they let you edit it, which explicitly limits the size of the files you can view or edit. lfhex is designed to allow you to edit binary files larger than can fit into your computer's memory.

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) close_edit () AUTHORS
