# ForeignThon

Write Python in any human language.

ForeignThon is a transpiler that converts `.xx.py` files into standard Python — keywords, builtins, and exceptions all translated into your language. The compiled output runs anywhere without ForeignThon installed.

---

## How it works

```
source.es.py  →  fpy  →  source.compiled.py  →  Python
```

ForeignThon uses Python's `tokenize` module to swap `NAME` tokens. Strings, comments, and f-strings are never touched. The result is identical, valid Python.

## Install

```bash
pip install foreignthon
pip install foreignthon-es   # or any other language pack
```
