VBinDiff 3.0 beta 3 (Default branch)
06-26-2008
VBinDiff (Visual Binary Diff) displays files inhexadecimal and ASCII (or EBCDIC). It can alsodisplay two files at once and highlight thedifferences between them. Unlike diff, it workswell with large files (up to 4 GB).License: GNU General Public License (GPL)Changes:|

Algorithm::Diff::XS(3pm) User Contributed Perl Documentation Algorithm::Diff::XS(3pm) NAME
Algorithm::Diff::XS - Algorithm::Diff with XS core loop SYNOPSIS
# Drop-in replacement to Algorithm::Diff, but "compact_diff" # and C<LCSidx> will run much faster for large data sets. use Algorithm::Diff::XS qw( compact_diff LCSidx ); DESCRIPTION
This module is a simple re-packaging of Joe Schaefer's excellent but not very well-known Algorithm::LCS with a drop-in interface that simply re-uses the installed version of the Algorithm::Diff module. Note that only the "LCSidx" function is optimized in XS at the moment, which means only "compact_diff" will get significantly faster for large data sets, while "diff" and "sdiff" will run in identical speed as "Algorithm::Diff".
