A fortune quote: erage individual's position in any hierarchy is a lot like pulling a dogsled -- there's no real change of scenery except for the lead dog.

 * Examples of how to use bitwise operators
 *#

# Prints "01\n"
assert 0 == (put 1 and 0); 
assert 1 == (say 1 and 1); 

# Prints "01\n"
assert 0 == (put 0 or 0);
assert 1 == (say 0 or 1);

# Prints "01\n"
assert 0 == (put 1 xor 1);
assert 1 == (say 1 xor 0);

# Prints "82\n"
assert 8 == (put 2 :< 2);
assert 2 == (say 8 :> 2);

# A bit more complex, prints "9\n"
assert 9 == (say 1 :< 5 :> 5 or 2 and 5 xor 8);

# Same result, but with parenthesis:
assert 9 == (say ((((1 :< 5) :> 5) or 2) and 5) xor 8);

# Different parenthesis, different result: "1\n"
assert 1 == (say 1 :< 5 :> 5 or 2 and (5 xor 8));

# Prints "-1" 
assert (neg 1) == (say neg not 0);


#*
 * Simple examples how to write comments
 *#

# This is a single lined comment

say 1 + 1; # This is a comment at the end of the line

say 1 #* This is an embedded comment *# + 1;

#* This is
	a
		multiline
			comment *#

#* 
 * This is
 * a nicer looking
 * multiline comment

#*
 * Examples of how to use fork
 *#

my pid = fork;

if pid {
	put "I am the parent process and the child has the pid ";
	say pid;
}

#*
 * Examples of how to use functions
 *#

func foo {
	say 1 + a * 3 + b;

	func bar {
		say "Hello i am nested";
	}

	bar; # Calling nested
}

my a = 2, b = 4; # Create global variables
foo;
assert 0 == (defined bar); # bar is not available anymore

func baz {
	say "I am baz";
	undef baz; 
}

baz; # Baz deletes itself
assert 0 == (defined baz); # baz is not available anymore

#*
 * Simple builtin function tests
 *#

# Print "-20\n"
assert (neg 20) == (say neg 20);

# Print "30\n"
assert 30 == (say 10 - neg 20);

# Print "-30\n"
assert (neg 30) == (say neg neg neg 10 - neg 20);

# Print "Hello\n"
put "Hello";
ln;

# Exit with exit code 0
exit 10 + 10 - 5 - 15;


#*
 * Simple I/O examples. Currently only output is supported.
 *#

# Print out 10 followed by a newline
say 10; 

# Print out 20 without a newline followed
put 20;

# Print out a newline
ln;


#*
 * Examples of how to use procedures
 *#

proc foo {
	say 1 + a * 3 + b;
	my c = 6;
}

my a = 2, b = 4;

foo; # Run the procedure. Print out "11\n"
say c; # Print out "6\n";

proc bar {
	say "I am bar";

	undef baz;

	proc baz {
		say "I am baz";
	}
}

# Here bar would produce an error because the proc is not yet defined!
# bar; 

bar; # Here the procedure bar will define the procedure baz!
baz; # Now the procedure baz is defined!
bar; # Here the procedure bar will redefine baz again!

#*
 * Examples of how to use scopeing
 *#

my foo = 1;

{
	# Prints out 1
	assert 1 == (put defined foo);

	{
		my bar = 2;

		# Prints out 1
		assert 1 == (put defined bar);

		# Prints out all available symbols at
		# the current program position.
		scope;
	}

	# Prints out 0
	assert 0 == (put defined bar);

	my baz = 3;
}

# Prints out 0
assert 0 == (say defined bar);



#*
 * Examples of how to use synonyms
 *#

# Create a variable foo, and bar is a synonym for foo
my foo = "foo";
my bar = \foo;

# Reset the value of foo
foo = "bar";

# The synonym variable should now also set to "bar"
assert "bar" == say bar;

# Create a new procedure baz
proc baz { 
	say "I am baz";
}

# Make a synonym baz, and undefine baz
my bay = \baz;

# Should be the num of syms for the same value
assert 2 == syms baz;
assert 2 == syms bay;
undef baz;
assert 1 == syms bay;

# bay still has a reference of the original procedure baz
bay; # this prints aut "I am baz" 

assert 0 == defined baz;
assert 1 == defined bay;

# This removes the procedure from memory
undef bay; 


#*
 * Examples how to convert types
 *#

assert 1 == say 1; # Integer output

assert 1 == say double 1; # Double output

assert 14 == say 1 + string 13; # Implicit type conversion to Integer

assert 2 == say integer 2.8; # Rounds down to the Integer 2

assert say integer double string put say neg 12; # Nonsense but working :)


#*
 * Examples of how to define variables
 *#

# Defines the variables 
my foo = 1 + 1;
my bar = 4 - 1, baz = 100 + 1, bay;

# bay has been initialized with the default value of 0
say bay;

# Prints out "5\n"
assert 5 == (say foo + bar);

# Pritns out "51101\n"
assert 51 == (put baz - 50);
assert 101 == (say baz);

# Change the value of the variable to 99 and print it out
assert 99 == (baz = 99);
say baz;
