in reply to ParagraphDiff Module, modify input type?

You must not have read the documentation for that module too closly because it looks like it already does what you want! In fact, here's an example from the synopsis:

print text_diff(["old"], ["new"]);     # T-Diff 2 plain strings (a FAQ
+)

    Okay, that does work! I can't believe I missed that. That is my life with reading documentation though.

    So now my question is, how do I make those variables instead of just plain text? 

    #!/usr/bin/perl -w
use strict;
use Text::ParagraphDiff;

my $old = 'this is the oooooooold textt';
my $new = 'this is the new text';

print text_diff(["$old"], ["$new"]);

    This doesn't work and gives you a bunch of errors: 
    Use of uninitialized value in string eq at /Library/Perl/5.8.1/Text/Pa
+ragraphDiff.pm line 197.

    There must be a way to do that because I am afraid that some of my text might break that because some of it is 20 pages long and has all sorts of paragraphs, breaks, etc.

    THANKS!
