text::worddiff::html

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

Name
       Text::WordDiff::HTML - XHTML formatting for Text::WordDiff

Synopsis
	   use Text::WordDiff;

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

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

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::HTML formats word diffs for viewing in a Web browser. The diff content is highlighted as follows:

       o   "<div class="file">"

	   This element contains the entire contents of the diff "file" returned by "word_diff()". All of the following elements are subsumed by
	   this one.

	   o   "<span class="fileheader">"

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

		 --- in.txt    Thu Sep	1 12:51:03 2005
		 +++ out.txt   Thu Sep	1 12:52:12 2005

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

	   o   "<span class="hunk">"

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

	       o   "<ins>"

		   Inserted content.

	       o   "<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.
