Asula Lang

Asula Lang is a language exploring new syntax methods.

For example, variables do not use = signs:

var i(5)

There are no semicolons.

Example programs

These are simple programs to show you around Asula! The file extension for a typical Asula file is .asu. For example main.asu is the main file you run. See more programs...

Hello, World

print("Hello World!")

Null Type

() is actually the null type!

print(()) # => ()
var a(()) # same as var a()
if (a == ())
    print("a is null! Proof: " + a) # <= ()
else
    print("a has a value! a:" + a)
end

Blocks

block
    var a(5)
    block
        var a(3)
        print(a)
    end
    print(a)
end

Functions

def sum(a, b, c)
    ret(a + b + c)
end

print(sum(1, 2, 3))

Modules

Asula can directly execute a file you give it, unlike europa lang.

$("./hello.asu")
print("World!")

# ./hello.asu
print("Hello, ")

Classes

Unlike europa lang, there are classes in asula!

class Animal
    def new(species)
        self.species = species
    end

    def identify()
        print(self.species)
    end
end

class Dog : Animal
    def new(species)
        super(species)
    end
end

super and self are automatically defined 'variables' you can use.

Control Flow

You can either use ternary or if statements, however, unlike europa, if statements are not expressions.

var a(5), b(6)

if (a > b)
    print("a > b")
elif (a < b)
    print('a < b')
else
    print("a = b")
end

Europa Lang

Asula is in a way related to europa lang. Originally, someone else was meant to create asula lang (J4Mirror), however, they never did, so I will!

Now, if I get an Option::unwrap() on a None value, I can go here for a segfault!
