Chroma

Simple interpreter written in C

1. Introduction

// fibonacci.chr
function fib(N) {
    if (N < 2) {
        return 1;
    }
    else {
        return fib(N - 1) + fib(N - 2);
    }
}

Chroma is a simple programming language that supports variables, arrays, functions and classes and more. It is planned to be compatible with C.

Some external features such as basic IO can be imported from C libraries.

2. Features

Chroma has 6 basic datatypes; number, string, array, function, class, object. Chroma stores data in a struct named Value, and each variable holds the reference for Value, in other word, Value*.

number is equal to double type in C. Chroma does not have a seperate int type; number itself includes both int and double.

string is equal to char* type in C. string can be indexed, and concatenated by +.

array is an array of Value*, therefore, and datatypes can be stored in a single array. array should be initialized by a given length.

function and class are technically implemented same in chroma, as they are both invokable. This means these datatypes can be invoked(called), with creates an object. However, a function returns the return value of the object, while class returns the object itself.

Chroma function supports major features that other programming language does; recursion, closures and more.
