Class super functions

there is some Super functions to handle classes at runtime.

Checking class exists

You can check a class exists with class.exists function:

if class.exists('some_class')
    # ...
endif

Geting list of all of classes

You can get list of all of classes with class.list function:

$classes = class.list()

println($classes)

output:

['a', 'b', '...']

The output is a list.

Deleting a class

You can delete a class at runtime with func.delete function:

class.delete('some_class')

Puting classes into variables

Classes are like variables, you can put them into variables and use them.

look at this example:

class Person
    $name

    func __init__($name)
        $this->name = $name
    endfunc

    func say_hi()
        println('hello ' + $this->name)
    endfunc
endclass

# puting the class into the variable
$myclass = Person

# calling the variable
$person1 = $myclass('pashmak')
$person1->say_hi()

output:

hello pashmak

Also you can change value of classes. classes are like variables and can be changed.

For example:

class Foo
    $name = 'the foo'
endclass

class Bar
    $name = 'the bar'
endclass

$a = Foo()
$b = Bar()
println($a->name)
println($b->name)

Foo = Bar

$a = Foo()
$b = Bar()
println($a->name)
println($b->name)

output:

the foo
the bar
the bar
the bar
