=head1 SYNOPSIS
This is the base class for App::Ack::Resources, an iterator factory
for App::Ack::Resource objects.
=head1 METHODS
=head2 from_argv( \%opt, \@starting_points )
Return an iterator that does the file finding for us.
=cut
sub from_argv {
my $class = shift;
my $opt = shift;
my $start = shift;
my $self = bless {}, $class;
my $file_filter = undef;
my $descend_filter = $opt->{descend_filter};
if( $opt->{n} ) {
$descend_filter = sub {
return 0;
};
}
$self->{iter} =
File::Next::files( {
file_filter => $opt->{file_filter},
descend_filter => $descend_filter,
error_handler => sub { my $msg = shift; App::Ack::warn( $msg ) },
sort_files => $opt->{sort_files},
follow_symlinks => $opt->{follow},
}, @{$start} );
return $self;
}
=head2 from_file( \%opt, $filename )
Return an iterator that reads the list of files to search from a
given file. If I<$filename> is '-', then it reads from STDIN.

my $class = shift;
