=head1 NAME

Acme::Be::Modern - enables your script to "be modern"

=head1 VERSION

Version 0.04

=cut

our $VERSION = '0.04';


=head1 SYNOPSIS

This is a thin (and stupid) wrapper (actually a source filter) around
L<Modern::Perl>. It makes it possible to write 'be modern' instead of
'use Modern::Perl' - like this:

    use Acme::Be::Modern;

    be modern; # all lowercase is actually postmodern :-/
    ...

=cut

=head1 WARNING

The source filter (defined in the L<Acme::Be::Modern::filter> sub is
simply a naive search-and-replace. Don't use this in any real code.

=head1 IMPLEMENTATION

The implementation is a slight variation of the example in
L<perlfilter>. It's implemented using two functions:

=head2 import

This will be called after L<Acme::Be::Modern> has been loaded. Simply
calls filter_add() with a blessed reference. Now the filter is
activated.

=cut

sub import {
    my ($type) = @_;
    my ($ref) = [];
    filter_add(bless $ref);
}


=head2 filter

The actual filter. Will receive source lines by calling
filter_read(). Any occurrence (and I mean any) of 'be modern' will be
replace with 'use Modern::Perl'.

=cut

sub filter {
    my ($self) = @_;
    my ($status);
    s/be modern/use Modern::Perl/g if ($status = filter_read()) > 0;
    $status;
}

=head1 AUTHOR

=head1 BUGS

Yes! This is buggy. It's a source filter, and it's really stupid. Any
text in your source matching 'be modern' will be replaced with 'use
Modern::Perl'.
