Scripting-language-interpreter

A full-featured scripting language interpreter based on Crafting Interpreters. This interpreter handles scripts written in the Lox language, a high-level scripting language based on the ECMA specifications of JavaScript.

About this project

This project is at the forefront of an open-source serious game (currently in pre-production). The goal is to write a scripting language interpreter that can perform runtime behaviour in game engines like Unity.

The interpreter

This interpreter performs a few steps when receiving input:

1. Lexical analysis
2. Parsing
3. Static analysis
4. Intermediate representation
5. Optimization
6. Code generation
7. Runtime representation

The Lox language

Lox is similair to high-level scripting languages like JavaScript and Lua. Two of the main aspects are:

• Dynamic typing
• Automatic memory management

Besides those aspects Lox can handle:

• Data types
• Expressions
• Statements
• Variables
• Control flows
• Functions
• Classes

An example of Lox code:

// This is a test
var test = 5;
for (var i = 0; i < test; i = i + 1)
{
    print i;
}
