=head2 Functions

=over 4

=item blessed_ok( SCALAR )

Ok if the SCALAR is a blessed reference.

=cut

sub blessed_ok ($;$) {
	my $ref  = ref $_[0];
	my $ok   = Scalar::Util::blessed($_[0]);
	my $name = $_[1] || 'Scalar is blessed';

	$Test->diag("Expected a blessed value, but didn't get it\n\t" .
		qq|Reference type is "$ref"\n| ) unless $ok;

	$Test->ok( $ok, $name );
	}

=item defined_ok( SCALAR )

Ok if the SCALAR is defined.

=cut

sub defined_ok ($;$) {
	my $ok   = defined $_[0];
	my $name = $_[1] || 'Scalar is defined';

	$Test->diag("Expected a defined value, got an undefined one\n", $name )
		unless $ok;

	$Test->ok( $ok, $name );
	}

=item undef_ok( SCALAR )

Ok if the SCALAR is undefined.

=cut

sub undef_ok ($;$) {
	my $name = $_[1] || 'Scalar is undefined';

	if( @_ > 0 ) {
		my $ok   = not defined $_[0];

		$Test->diag("Expected an undefined value, got a defined one\n")
			unless $ok;

		$Test->ok( $ok, $name );
		}
	else {
		$Test->diag("Expected an undefined value, but got no arguments\n");

		$Test->ok( 0, $name );
		}
	}

=item dualvar_ok( SCALAR )

Ok if the scalar is a dualvar.

How do I test this?

sub dualvar_ok ($;$)
	{
	my $ok   = Scalar::Util::dualvar( $_[0] );
	my $name = $_[1] || 'Scalar is a dualvar';

	$Test->ok( $ok, $name );

	$Test->diag("Expected a dualvar, didn't get it\n")
		unless $ok;
	}

=cut

=item greater_than( SCALAR, BOUND )

Ok if the SCALAR is numerically greater than BOUND.

=cut

sub greater_than ($$;$) {
	my $value = shift;
	my $bound = shift;
	my $name  = shift || 'Scalar is greater than bound';

	my $ok = $value > $bound;

	$Test->diag("Number is less than the bound.\n\t" .
		"Expected a number greater than [$bound]\n\t" .
		"Got [$value]\n") unless $ok;

	$Test->ok( $ok, $name );
	}

=item length_ok( SCALAR, LENGTH )

Ok if the length of SCALAR is LENGTH.

=cut

sub length_ok ($$;$) {
	my $string = shift;
	my $length = shift;
	my $name   = shift || 'Scalar has right length';

	my $actual = length $string;
	my $ok = $length == $actual;

	$Test->diag("Length of value not within bounds\n\t" .
		"Expected length=[$length]\n\t" .
		"Got [$actual]\n") unless $ok;

	$Test->ok( $ok, $name );
	}

=item less_than( SCALAR, BOUND )

Ok if the SCALAR is numerically less than BOUND.

=cut

sub less_than ($$;$) {
	my $value = shift;
	my $bound = shift;
	my $name  = shift || 'Scalar is less than bound';

	my $ok = $value < $bound;

	$Test->diag("Number is greater than the bound.\n\t" .
		"Expected a number less than [$bound]\n\t" .
		"Got [$value]\n") unless $ok;

	$Test->ok( $ok, $name );
	}

=item maxlength_ok( SCALAR, LENGTH )

Ok is the length of SCALAR is less than or equal to LENGTH.

=cut

sub maxlength_ok($$;$) {
	my $string = shift;
	my $length = shift;
	my $name   = shift || 'Scalar length is less than bound';

	my $actual = length $string;
	my $ok = $actual <= $length;

		"Expected max=[$length]\n\tGot [$actual]\n") unless $ok;

	$Test->ok( $ok, $name );
	}

=item minlength_ok( SCALAR, LENGTH )

Ok is the length of SCALAR is greater than or equal to LENGTH.

=cut

sub minlength_ok($$;$) {
	my $string = shift;
	my $length = shift;
	my $name   = shift || 'Scalar length is greater than bound';

	my $actual = length $string;
	my $ok = $actual >= $length;

	$Test->diag("Length of value shorter than expected\n\t" .
		"Expected min=[$length]\n\tGot [$actual]\n") unless $ok;

	$Test->ok( $ok, $name );
	}

=item number_ok( SCALAR )

Ok if the SCALAR is a number ( or a string that represents a
number ).

At the moment, a number is just a string of digits.  This needs
work.

=cut

sub number_ok($;$) {
	my $number = shift;
	my $name   = shift || 'Scalar is a number';

	$number =~ /\D/ ? $Test->ok( 0, $name ) : $Test->ok( 1, $name );
	}

=item number_between_ok( SCALAR, LOWER, UPPER )

Ok if the number in SCALAR sorts between the number
in LOWER and the number in UPPER, numerically.

If you put something that isn't a number into UPPER or
LOWER, Perl will try to make it into a number and you
may get unexpected results.

=cut

sub number_between_ok($$$;$) {
	my $number = shift;
	my $lower  = shift;
	my $upper  = shift;
	my $name   = shift || 'Scalar is in numerical range';

	unless( defined $lower and defined $upper ) {
		$Test->diag("You need to define LOWER and UPPER bounds " .
			"to use number_between_ok" );
		$Test->ok( 0, $name );
		}
	elsif( $upper < $lower ) {
		$Test->diag(
			"Upper bound [$upper] is lower than lower bound [$lower]" );
		$Test->ok( 0, $name );
		}
	elsif( $number >= $lower and $number <= $upper ) {
		$Test->ok( 1, $name );
		}
	else {
		$Test->diag( "Number [$number] was not within bounds\n",
			"\tExpected lower bound [$lower]\n",
			"\tExpected upper bound [$upper]\n" );
		$Test->ok( 0, $name );
		}
	}

=item string_between_ok( SCALAR, LOWER, UPPER )

Ok if the string in SCALAR sorts between the string
in LOWER and the string in UPPER, ASCII-betically.

=cut

sub string_between_ok($$$;$) {
	my $string = shift;
	my $lower  = shift;
	my $upper  = shift;
	my $name   = shift || 'Scalar is in string range';

	unless( defined $lower and defined $upper ) {
		$Test->diag("You need to define LOWER and UPPER bounds " .
			"to use string_between_ok" );
		$Test->ok( 0, $name );
		}
	elsif( $upper lt $lower ) {
		$Test->diag(
			"Upper bound [$upper] is lower than lower bound [$lower]" );
		$Test->ok( 0, $name );
		}
	elsif( $string ge $lower and $string le $upper ) {
		$Test->ok( 1, $name );
		}
	else {
		$Test->diag( "String [$string] was not within bounds\n",
			"\tExpected lower bound [$lower]\n",
			"\tExpected upper bound [$upper]\n" );
		$Test->ok( 0, $name );
		}

	}

=item readonly_ok( SCALAR )

Ok is the SCALAR is read-only.

=cut

sub readonly_ok($;$) {
	my $ok   = not Scalar::Util::readonly( $_[0] );
	my $name = $_[1] || 'Scalar is read-only';

	$Test->diag("Expected readonly reference, got writeable one\n")
		unless $ok;

	$Test->ok( $ok, $name );
	}

=item ref_ok( SCALAR )

Ok if the SCALAR is a reference.

=cut

sub ref_ok($;$) {
	my $ok   = ref $_[0];
	my $name = $_[1] || 'Scalar is a reference';

	$Test->diag("Expected reference, didn't get it\n")
		unless $ok;

	$Test->ok( $ok, $name );
	}

=item ref_type_ok( REF1, REF2 )

Ok if REF1 is the same reference type as REF2.

=cut

sub ref_type_ok($$;$) {
	my $ref1 = ref $_[0];
	my $ref2 = ref $_[1];
	my $ok = $ref1 eq $ref2;
	my $name = $_[2] || 'Scalar is right reference type';

	$Test->diag("Expected references to match\n\tGot $ref1\n\t" .
		"Expected $ref2\n")	unless $ok;

	ref $_[0] eq ref $_[1] ? $Test->ok( 1, $name ) : $Test->ok( 0, $name );
	}

=item strong_ok( SCALAR )

Ok is the SCALAR is not a weak reference.

=cut

sub strong_ok($;$) {
	my $ok   = not Scalar::Util::isweak( $_[0] );
	my $name = $_[1] || 'Scalar is not a weak reference';

	$Test->diag("Expected strong reference, got weak one\n")
		unless $ok;

	$Test->ok( $ok, $name );
	}

=item tainted_ok( SCALAR )

Ok is the SCALAR is tainted.

(Tainted values may seem like a not-Ok thing, but remember, when
you use taint checking, you want Perl to taint data, so you
should have a test to make sure it happens.)

=cut

sub tainted_ok($;$) {
	my $ok   = Scalar::Util::tainted( $_[0] );
	my $name = $_[1] || 'Scalar is tainted';

	$Test->diag("Expected tainted data, got untainted data\n")
		unless $ok;

	$Test->ok( $ok, $name );
	}

=item untainted_ok( SCALAR )

Ok if the SCALAR is not tainted.

=cut

sub untainted_ok($;$) {
	my $ok = not Scalar::Util::tainted( $_[0] );
	my $name = $_[1] || 'Scalar is not tainted';

	$Test->diag("Expected untainted data, got tainted data\n")
		unless $ok;

	$Test->ok( $ok, $name );
	}

=item weak_ok( SCALAR )

Ok if the SCALAR is a weak reference.

=cut

sub weak_ok($;$) {
	my $ok = Scalar::Util::isweak( $_[0] );
	my $name = $_[1] || 'Scalar is a weak reference';

	$Test->diag("Expected weak reference, got stronge one\n")
		unless $ok;

	$Test->ok( $ok, $name );
	}
