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' };

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:

• <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.

  • <span class="fileheader">

    The header section for the files being diffed, 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.

  • <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.
