An interpreter for the Monkey programming language written in Rust

![The Monkey Programming Language](https://cloud.githubusercontent.com/assets/1013641/22617482/9c60c27c-eb09-11e6-9dfa-b04c7fe498ea.png)

## What’s Monkey?

Monkey has a C-like syntax, supports **variable bindings**, **prefix** and **infix operators**, has **first-class** and **higher-order functions**, can handle **closures** with ease and has **integers**, **booleans**, **arrays** and **hashes** built-in.

Official site is: https://monkeylang.org/. It's has various implementation languages :).

There is a book about learning how to make an interpreter: [Writing An Interpreter In Go](https://interpreterbook.com/#the-monkey-programming-language). This is where the Monkey programming language come from.

## Features

- Split packages to make everything minimum

- **REPL**: A Read-Eval-Print-Loop (REPL) for Monkey tokenizer, parser, evaluator, compiler

- location info for ast

- test for every module

- **Wasm**: A WebAssembly target, thus run monkey on browser is directly supported.

- bytecode viewer from source
