Lyron

A... programming language...

NOTE: It is a work in progress..

Syntax

• Note: The syntax might (and most probably will) undergo changes.

• Functions:

  • Defining a function

    def sum(a:i32, b:i32) -> i32
        a+b
    end 
    

  • Calling a function

    sum(a, b)
    

• Class

  • A class in lyron is just a collection of functions and attributes
  • Constructors should have the same name as the class. Eg:

    class Animal{
        def Animal(self: Self, age: i32)->Animal do
            print("i'm an animal ")
            print("i'm "+age+" years old.")
            self = setattr(self, "age", age) # `self.age = age` is invalid!
            self
        end
    
        def sound(self: Self) -> Animal
            print("i make a sound")
    }
    

• Variables:

  • Declaration:

    let x: i32    
    

  • Assignment:

    x = 42 
    

  Note: Both need to be done separately.

• Operations

  • Available operations =, +, -, *, /, ==, !=, <, >, <=, >=, +=, -=, *=, /=

    let a:i32 = (-b + 5) - 10 / -(5 - -2)
    

• Comments

  • Comments start with # and continue until the end of the line

    # this is a comment
    

• Programs

  • A program consists of just top-level functions, classes, and expressions.
