[Templates] On hacking a Filter to use an external binary.

[Sherwood Botsford]

I asked a similar question a few years ago, and didn't understand the
answers.  I really don't understand the care and feeding of modules.

Here's what I'm starting with:

#$Id: MultiMarkdown.pm 4103 2009-03-02 20:41:50Z andrew $
package Template::Plugin::MultiMarkdown;
use strict;
use base qw (Template::Plugin::Filter);
use Text::MultiMarkdown;

our $VERSION = 0.03;

sub init {
    my $self = shift;
    $self->{_DYNAMIC} = 1;
    $self->install_filter($self->{_ARGS}->[0] || 'multimarkdown');
    return $self;
}

sub filter {
    my ($self, $text, $args, $config) = @_;
    my $m = Text::MultiMarkdown->new(%{$config || {}});
    return $m->markdown($text);
}

1;

******

I want to change the reference to Text:MultiMarkdown
to use /usr/local/bin/multimarkdown

I think I need to change:
use Text::MultiMarkdown;
To
use IPC::run3

and then the my $m line involves a call to run3, but then I'm lost.

Sherwood
