Verse

verse is an interpreter for the Verse programming language. This language was the result of various experimentations that ultimetly led to Basalt, my second language. It's important to note that what i created has nothing to do with Verse made by epic games.

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.

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

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.

$ 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.

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:

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.

$$ verse -r fibo.verse
