       Text::Flow - Flexible text flowing and word wrapping for not just ASCII output.


         use Text::Flow;

         # use it on ASCII text ...
         my $flow = Text::Flow->new(
             check_height => sub {
                 my $paras = shift;
                 sum(map { scalar @$_ } @$paras) <= 10;
             wrapper => Text::Flow::Wrap->new(
                 check_width  => sub { length($_[0]) < 70 }

         my @sections = $flow->flow($text);

         # @sections will now be an array of strings, each string
         # will contain no more than 10 lines of text each of which
         # will be no longer then 70 characters long

         # or use it on text in a PDF file ...
         my $flow = Text::Flow->new(
             check_height => sub {
                 my $paras = shift;
                 (sum(map { scalar @$_ } @$paras) * $pdf->get_font_height) < 200;
             wrapper => Text::Flow::Wrap->new(
                 check_width => sub {
                     my $string = shift;
                     $pdf->get_string_width($string) < 100

         my @sections = $flow->flow($text);

         # @sections will now be an array of strings, each string
         # will contain text which will fit within 200 pts and
         # each line will be no longer then 100 pts wide


       This module provides a flexible way to wrap and flow text for both ASCII and non-ASCII

   Another Text Wrap module!!?!?!
       The main purpose of this module is to provide text wrapping and flowing features without
       being tied down to ASCII based output and fixed-width fonts. My needs were for a more
       sophisticated text control in PDF and GIF output formats in particular.


       new (%params)
           This constructs the new Text::Flow instance, and accepts parameters for the "wrapper"
           and "check_height" variables.

       wrapper (?$wrapper)
           This is the accessor for the internally help Text::Flow::Wrapper instance which is
           used by Text::Flow to wrap the individual lines.

           This is the accessor for the CODE ref which is used to check the height of the current
           paragraph. It gets as an argument, an array-ref of paragraphs, each of which is also
           an array-ref of text lines. The most common usage is shown in the SYNOPSIS above, but
           you can really do anything you want with them. It is expected to return a Boolean
           value, true if the height is still okay, and false if the max height has been reached.

       flow ($text)
           This method preforms the text flowing. It returns an array of strings which can be
           treated as complete blocks of text. It will handle paragraph breaks and line breaks
           for you.

           Returns the Moose meta object associated with this class.


       I wanted to write some tests for using this with GD modules as well. I suppose we will
       have to wait until 0.02 for that.


       There are a bunch of other text wrapping and flowing modules out there, but they are all
       meant for use in ASCII outout only. This just didn't work for my needs, so I wrote this
       one. If you need to wrap ASCII text and want to do it in a much simpler manner then this
       module provides, then I suggest checking out those modules. This module is specifically
       made for when those other modules are no longer powerful and flexible enough.


       All complex software has bugs lurking in it, and this module is no exception. If you find
       a bug please either email me, or add the bug to cpan-RT.
