# Verse

Verse is an interpreter for the Verse programming language. In the future, the goal is to evolve this project into an all-in-one bundle made of an interpreter, a compiler, and a debugger.

Verse is designed to be compiled directly to machine code, and offers all the features a low level language would, while still being able to be interpreted like languages like Python or Ruby (enhancing portability, and reducing wasted time by removing the need to perform a full compilation of your code-base just to run unit-tests).

### Installation (Building from source)

In order to install verse, you have to build it from source. By default, the build process tries to use `clang++`, but you can change that

to make it use `g++` instead if you so desire. Either way `c++20` or higher is required.

```bash

$$ git clone https://www.github.com/fDero/Verse

$$ cd Verse

$$ make build

```

### Hello World

To make your first hello-world program in verse, all it takes is to create a file with the `.verse` extension (in this case, it will be called `hello.verse`)

containing the following code:

```go

func main(){

    println("Hello world!");

}

```

Once you have the file set up, to run it just use the `verse -r hello.verse` command in console.

```bash

$$ verse -r hello.verse

$$ Hello world!

```

### Types

Verse is a strictly typed language, it has a C-style type system with `Int`, `Float`, `Bool`, `Char`, `String` as primitive types. 

```go

func main(){

    var x : Int = 6;

    var y : Float = 9.4;

    var f : Bool = false;

    var c : Char = 'z';

    var s : String = "hello world";

}

```

### Recursion

Verse supports recursion just like any other language, and a good way to show it is with the classic fibonacci example, consider the following code:

```go

func fibo(n : Int){

    if (n < 2) {

        return 1;

    }

    else {

        return fibo(n-1) + fibo(n-2);

    }

}

func main(){

    println(fibo(6));

}

```

assuming the file is called `fibo.verse`, then it can be executed just like we did earlier with the hello-world example, using the `verse -r` command.

```bash

$$ verse -r fibo.verse

$$ 21

```
