       Text::WordDiff::HTMLTwoLines - XHTML formatting for Text::WordDiff with content on two
       lines

Synopsis

           use Text::WordDiff;

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

           # May also mix input types:
           my $diff = word_diff \@records1,  'file_B.txt', { STYLE => 'HTMLTwoLines' };

Description

       This class subclasses Text::WordDiff::Base to provide a XHTML formatting for
       Text::WordDiff. See Term::WordDiff for usage details. This class should never be used
       directly.

       Text::WordDiff::HTMLTwoLines formats word diffs for viewing in a Web browser.  The output
       is similar to that produced by Term::WordDiff::HTML but the two lines (or files, records,
       etc.) are shown separately, with deleted items highlighted in the first line and inserted
       items highlighted in the second. HTMLTwoLines puts a span tag around each word or set of
       words in the diff.

       The diff content is highlighted as follows:

       •   "<div class="file">"

           The inputs to "word_diff()" are each contained in a div element of class "file". All
           the following results are subsumed by these elements.

           •   "<span class="fileheader">"

               The header section for the files being "diff"ed, usually something like:

                 --- in.txt    Thu Sep  1 12:51:03 2005

               for the first file, and

                 +++ out.txt   Thu Sep  1 12:52:12 2005

               for the second.

               This element immediately follows the opening "file" "<div>" element, but will not
               be present if Text::WordDiff cannot determine the file names for both files being
               compared.

           •   "<span class="hunk">"

               This element contains a single diff "hunk". Each hunk may contain the following
               elements:

               •   "<ins>"

                   Inserted content.

               •   "<del>"

                   Deleted content.

       You may do whatever you like with these elements and classes; I highly recommend that you
       style them using CSS. You'll find an example CSS file in the eg directory in the Text-
       WordDiff distribution.
