A custom programming language interpreter written in Rust.

Description

This project is a simple interpreter for a custom programming language. It features a lexer, parser, and an interpreter that evaluates the abstract syntax tree (AST).

Structure

Frontend:

src: String --[lexing]--> token --[parsing]--> program<statement<expression>>

Runtime:

runtime.evaluate(program)

Getting Started

Prerequisites

• Rust and Cargo must be installed on your system.

Building

To build the project, run the following command in the root directory:

cargo build

Running

The interpreter can be run in two modes:

1. Shell Mode: To start the interactive shell, run:

   cargo run -- shell

   You can then enter expressions at the prompt. To exit the shell, type exit.

2. File Mode: To execute a script file, run:

   cargo run -- <file_path>

   Replace <file_path> with the path to your script file.

Usage

The language supports basic expressions. Here is an example of what you can do in the shell:

> 1 + 2
NumberValue(3)
