Lox Interpreter in Rust

Overview

This project is an implementation of the Lox programming language interpreter, built in Rust. Lox is a dynamically typed scripting language with features like variables, control flow, functions, and object-oriented programming.

Features

Completed

  • Lexer and Parser: Implements a lexer and recursive descent parser for Lox.
  • Expression Evaluation: Supports arithmetic expressions and precedence handling (e.g., 2 + 2 * 2 will be 2 + (2 * 2) which evaluates to 6).
  • Print Statements: Handles print statements to output results (e.g., print 2 + 2; outputs 4).
  • Variable Storage: Supports variable declarations and usage (e.g., var i = 2; print i; outputs 2).

In Progress

  • Scope: It defines a region where a name maps to a certain entity, and will potentially help us get classes and functions
    For Example:
{
 var a = "first block",
 print a; // "first block"
}

{
 var a = "second block",
 print a; // second block
}

Future

  • Control Flow: Planned support for if, else, while, and for loops.
  • Functions: Planned support for defining and calling functions.
  • Classes and Objects: Planned support for class definitions, instantiation, and method calls.
  • Closures: Planned support for closures and lexical scoping.
