Create a new programming language

What a fascinating task! Creating a new programming language is a significant undertaking, but I'll provide a high-level overview of a language I'll call "Lumina". Please note that this is a simplified example, and a real-world language would require much more detail and complexity.

Lumina Language Overview

Lumina is a statically-typed, object-oriented language that aims to provide a balance between simplicity, expressiveness, and performance. It's designed to be easy to learn and use, with a focus on building robust and maintainable software systems.

Syntax

Lumina's syntax is inspired by languages like Python, Java, and C#. It uses a combination of indentation and keywords to define the structure of the code.

Basic Syntax Elements

Variables: Variables are declared using the let keyword, followed by the variable name and its type. For example: let x: int = 5;
Functions: Functions are defined using the fn keyword, followed by the function name and its parameters. For example: fn greet(name: string) { print("Hello, " + name + "!"); }
Control Flow: Lumina supports if-else statements, loops (for, while, do-while), and conditional expressions.
Data Types: Lumina has the following built-in data types:
- int: 32-bit integer
- float: 64-bit floating-point number
- string: Unicode string
- bool: Boolean value
- null: Null value
- any: Dynamic type that can hold any value

Object-Oriented Programming

Lumina supports object-oriented programming (OOP) concepts like classes, inheritance, polymorphism, and encapsulation.

Classes: Classes are defined using the class keyword, followed by the class name and its properties. For example: class Person { name: string; age: int; }
Inheritance: Classes can inherit properties and behavior from parent classes using the extends keyword. For example: class Employee extends Person { salary: float; }
Polymorphism: Lumina supports method overriding and overloading.
Encapsulation: Classes can have private properties and methods, which can be accessed only through public methods.

Additional Features

Type Inference: Lumina has a type inference system, which can automatically infer the types of variables and expressions.
Garbage Collection: Lumina has a garbage collector that automatically manages memory allocation and deallocation.
Error Handling: Lumina has a built-in error handling mechanism that allows developers to catch and handle exceptions.

Example Code

Here's an example of a simple Lumina program:

let greeting: string = "Hello, World!";
fn main() {
    print(greeting);
    let person: Person = new Person("John", 30);
    print(person.name + " is " + person.age + " years old.");
}

class Person {
    name: string;
    age: int;

    constructor(name: string, age: int) {
        this.name = name;
        this.age = age;
    }
}

This code defines a greeting variable, a main function that prints the greeting, and a Person class with a constructor and properties. The main function creates a new Person object and prints its name and age.

Conclusion

Lumina is a new programming language that aims to provide a balance between simplicity, expressiveness, and performance. While this is just a high-level overview, I hope it gives you an idea of what a new language could look like. Of course, there are many details that would need to be fleshed out to create a fully functional language.
