See L<Term::WordDiff|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: =over =item * C<< <div class="file"> >> This element contains the entire contents of the diff "file" returned by C<word_diff()>. All of the following elements are subsumed by this one. =over =item * C<< <span class="fileheader"> >> The header section for the files being C<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" C<< <div> >> element, but will not be present if Text::WordDif cannot deterimine the file names for both files being compared. =item * C<< <span class="hunk"> >> This element contains a single diff "hunk". Each hunk may contain the following elements: =over =item * C<< <ins> >> Inserted content. =item * C<< <del> >> Deleted content. =back =back =back 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 F<eg> directory in the Text-WordDiff distribution. =head1 See Also =over =item L<Text::WordDiff|Text::WordDiff> =item L<Text::WordDiff::ANSIColor|Text::WordDiff::ANSIColor> =back =head1 Bugs Please send bug reports to <bug-text-worddiff@rt.cpan.org>. =head1 Author =begin comment Fake-out Module::Build.
