=head1 NAME
Template::Plugin::Wrap - Plugin interface to Text::Wrap
=head1 SYNOPSIS
[% USE wrap %]
# call wrap subroutine
[% wrap(mytext, width, initial_tab, subsequent_tab) %]
# or use wrap FILTER
[% mytext FILTER wrap(width, initital_tab, subsequent_tab) %]
=head1 DESCRIPTION
This plugin provides an interface to the Text::Wrap module which
provides simple paragraph formatting.
It defines a '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 'wrap' filter which accepts the same three optional
arguments but takes the input text directly via the filter input.
[% FILTER bullet = wrap(40, '* ', ' ') -%]
First, attach the transmutex multiplier to the cross-wired quantum
homogeniser.
[%- END %]
[% FILTER bullet -%]
Then remodulate the shield to match the harmonic frequency, taking
care to correct the phase difference.
[% END %]
Output:
* First, attach the transmutex
multiplier to the cross-wired quantum
homogeniser.
* Then remodulate the shield to match
the harmonic frequency, taking
care to correct the phase difference.
