=head1 Name
Text::WordDiff::ANSIColor - ANSI colored formatting for Text::WordDiff
=head1 Synopsis
use Text::WordDiff;
my $diff = word_diff 'file1.txt', 'file2.txt';
my $diff = word_diff \$string1, \$string2, { STYLE => 'ANSIColor' };
my $diff = word_diff \*FH1, \*FH2; \%options;
my $diff = word_diff \&reader1, \&reader2;
my $diff = word_diff \@records1, \@records2;
# May also mix input types:
my $diff = word_diff \@records1, 'file_B.txt';
=head1 Description
This class subclasses Text::WordDiff::Base to provide a formatting class for
Text::WordDiff that uses ANSI-standard terminal escape sequences to highlight
deleted and inserted text. This formatting class is the default class used by
L<Text::WordDiff|Text::WordDiff>; see its documentation for details on its
interface. This class should never be used directly.
Text::WordDiff::ANSIColor formats word diffs for viewing in an ANSI-standard
terminal session. The diff content is highlighted as follows:
=over
=item Deletes
Deleted words will display in bold-faced red. The ANSI standard for
strikethrough is also used, but since it is not supported by most terminals,
likely will not show up.
=item Inserts
Inserted words will display in bold-faced, underlined green.
=back
All other content is simply returned.
