# RPyLox

This repository is an RPython implementation for Lox. Read more at https://craftinginterpreters.com/

## Prerequisite

### RPython and Python 2.7

This code base is built with RPython and PyPy 2.7. Please download PyPy repository and put it at the root.

```shell

wget https://downloads.python.org/pypy/pypy2.7-v7.3.14-src.tar.bz2

tar xf pypy2.7-v7.3.14-src.tar.bz2 && mv pypy2.7-v7.3.14-src pypy

```

PyPy 2.7 is based on Python 2.7. Please install Python 2.7 instead of Python 3.x.

## Build

You can use `Makefile` to build `rlox-jit` and `rlox-interp`.

`rlox-jit` supports meta-tracing compialtion and runs faster for loop-heavy programs for example.

```shell

make targetlox-jit

```

`rlox-interp` is an interpreter compiled by RPython.

```shell

make targetlox-interp

```
