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:

  • <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.
