mafiascript

A semi-serious dynamically-typed interpreted programming language. Made mostly for learning experience.

Check out the wiki for information about the language

Built with

• C++17
• g++ and Make
• The Flex scanner is used, alongside the Bison parser generator.

Features

• Functional. Check out the examples page for working examples.
• All common programming language features are implemented:
  • Variables and scopes
  • string, number, bool, null, array ([]), object ({}) and function (() => {}) literals.
  • If statements and ternery
  • for and while loops, combined in a single keyword (loop)
  • All types have properties.

What's missing

• Detailed and useful error messages
• An actual call stack

Example

Get a number in the fibonacci sequence in mafiascript:

const fibonacci = (n) => {
   if (!n) return 0;
   const arr = [0, 1];
   loop (let i=2, i <= n, i += 1) {
      arr[i] = arr[i - 1] + arr[i - 2];
   };
   return arr[n];
};

fibonacci(10); // 55

How to build and run

Requirements:

• gcc or any other C++ compiler that supports C++17.
• Flex and Bison installed and included in path.

Setup:

• Clone this repository
• In the root directory of this repo, run make. You may have to edit the make file accordingly if you are using a different compiler.
• Run ./dist
• You can edit script.ms to run something different.
