It defines a C<wrap> subroutine which can be called, passing the input text and further optional parameters to specify the page width (default: 72), and tab characters for the first and subsequent lines (no defaults). [% USE wrap %] [% text = BLOCK %] First, attach the transmutex multiplier to the cross-wired quantum homogeniser. [% END %] [% wrap(text, 40, '* ', ' ') %] Output: * First, attach the transmutex multiplier to the cross-wired quantum homogeniser. It also registers a C<wrap> filter which accepts the same three optional arguments but takes the input text directly via the filter input. Example 1: [% FILTER bullet = wrap(40, '* ', ' ') -%] First, attach the transmutex multiplier to the cross-wired quantum homogeniser. [%- END %] Output: * First, attach the transmutex multiplier to the cross-wired quantum homogeniser. Example 2: [% FILTER bullet -%] Then remodulate the shield to match the harmonic frequency, taking care to correct the phase difference. [% END %] Output: * Then remodulate the shield to match the harmonic frequency, taking care to correct the phase difference. =head1 AUTHOR Andy Wardley E<lt>abw@wardley.orgE<gt> L<http://wardley.org/> The L<Text::Wrap> module was written by David Muir Sharnoff with help from Tim Pierce and many others. =head1 COPYRIGHT Copyright (C) 1996-2022 Andy Wardley.
