Text::WordDiff::ANSIColor(3pm)				User Contributed Perl Documentation			    Text::WordDiff::ANSIColor(3pm)

Name
       Text::WordDiff::ANSIColor - ANSI colored formatting for Text::WordDiff

Synopsis
	   use Text::WordDiff;

	   my $diff = word_diff 'file1.txt', 'file2.txt';
	   my $diff = word_diff $string1,   $string2,   { STYLE => 'ANSIColor' };
	   my $diff = word_diff *FH1,	     *FH2;	  \%options;
	   my $diff = word_diff &reader1,   &reader2;
	   my $diff = word_diff @records1,  @records2;

	   # May also mix input types:
	   my $diff = word_diff @records1,  'file_B.txt';

Description
       This class subclasses Text::WordDiff::Base to provide a formatting class for Text::WordDiff that uses ANSI-standard terminal escape
       sequences to highlight deleted and inserted text. This formatting class is the default class used by Text::WordDiff; see its documentation
       for details on its interface. This class should never be used directly.

       Text::WordDiff::ANSIColor formats word diffs for viewing in an ANSI-standard terminal session. The diff content is highlighted as follows:

       Deletes
	   Deleted words will display in bold-faced red. The ANSI standard for strikethrough is also used, but since it is not supported by most
	   terminals, likely will not show up.

       Inserts
	   Inserted words will display in bold-faced, underlined green.

       All other content is simply returned.
