text::patch

NAME

       Text::Patch - Patches text with given patch

SYNOPSIS

	   use Text::Patch;

	   $output = patch( $source, $diff, STYLE => "Unified" );

	   use Text::Diff;

	   $src  = ...
	   $dst  = ...

	   $diff = diff( $src, $dst, { STYLE => 'Unified' } );

	   $out  = patch( $src, $diff, { STYLE => 'Unified' } );

	   print "Patch successful" if $out eq $dst;

DESCRIPTION

       Text::Patch combines source text with given diff (difference) data.  Diff data is produced by Text::Diff module or by the standard diff
       utility (man diff, see -u option).

       patch( $source, $diff, options... )
	   First argument is source (original) text. Second is the diff data.  Third argument can be either hash reference with options or all the
	   rest arguments will be considered patch options:

	       $output = patch( $source, $diff, STYLE => "Unified", ... );

	       $output = patch( $source, $diff, { STYLE => "Unified", ... } );

	   Options are:

	     STYLE => 'Unified'

	   STYLE can be "Unified", "Context" or "OldStyle".

	   The 'Unified' diff format looks like this:
