Garbage Collector is WIP

Example 1

load "std/std.j"

:int test 5
if test bg 4
	puts 'test bg 4'
end
if test sm 5
	puts 'test sm 5'
elif test sm 6
	puts 'test sm 6'
end
if (test sm 5) or (test bg 4)
	puts 'hahaha'
end

puts "
--------------\n
"

:class a array
puts a
a.set 0,'1'
a.set 1,'2'
a.set 2,'['jfffdsjfdsjflkdsflkds',1,5]'
a.setString 3,'hahahaha'
puts a
puts a.size;
puts a.at 2;

output:

test bg 4
test sm 6
hahaha

[" jfffdsjfdsjflkdsflkds",1,5]

Adding a method

load 'std/' + "std.j"
class p
        fcn init string s
                @string s s
        end
end

fcn p$toString
        return string s
end

:class p p 'hahaha'
puts p

output:

hahaha

Operator overloading

load 'std/std.j'

class num
	fcn init int i
		@int v i
	end

	fcn '+' int i
		v v - i
	end

	fcn toString
		return string v
	end

end

:class n num 5
n."+" 4
puts n

output:

1

Modules

modules are special classes with an instance

load "std/std.j"
module print
	fcn puts string s
		puts s
		puts
		puts s
	end
end

print.puts 'Hello world!'

output:

Hello world!

Hello world!

Example 2

load "std/std.j"

class printer

	puts '-----'

	fcn init string s
		@string value s
	end

	fcn init
		printer$init nil
	end

	fcn print int times
		:int temp 0
		loop temp neq times
			puts value
			temp temp + 1
		end
	end

	fcn toString
		return string value
	end

	fcn setValue string s
		value s
	end
	
end

:class p printer
puts p
p.setValue "Hello world!"
puts p
p.print 5

output:

-----
$nil$
Hello world!
Hello world!
Hello world!
Hello world!
Hello world!
Hello world!
