Name

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.
