=head1 NAME

WWW::Mechanize::FormFiller::Value::Random::Chars - Fill characters into an HTML form field

=head1 SYNOPSIS

=for example begin

  use WWW::Mechanize::FormFiller;
  use WWW::Mechanize::FormFiller::Value::Random::Chars;

  my $f = WWW::Mechanize::FormFiller->new();

  # Create a random value for the HTML field "login"

  my $login = WWW::Mechanize::FormFiller::Value::Random::Chars->new(
                       login => set => 'alpha', min => 3, max => 8 );
  $f->add_value( login => $login );

  # Alternatively take the following shorthand, which adds the
  # field to the list as well :

  # If there is no password, put a random one out of the list there
  my $password = $f->add_filler( password => 'Random::Chars' );

=for example end

=for example_testing

  $f->fill_form($form);
  like( $form->value('login'), qr/^([a-zA-Z]+)$/, "Login gets set");
  like( $form->value('password'), qr/^([a-zA-Z]+)$/, "Password gets set");
