⚙️ Simple R to Python transpiler based on Tree Sitter

Rhyton - R to Python transpiler

📜 What is Rhyton

Rhyton is a type of ancient Greek drinking vessel that is in the shape of an animal's head or horn and has a hole in the bottom for pouring the liquid. It was often used in religious ceremonies or feasts.

The name came after combination of language names: R and Python

This library helps you to move R codebase to Python. Right now it supports conversion of math equations, expressions, conditions, function definitions and calls

🧲 Installation

The project is published on PyPi, so you can install it via pip

$: pip install rhyton

🚀 Launch

Use transpile or transpile_file to translate your R code

from rhyton import transpile, transpile_file

transpile('x <- 7') # returns transpiled string

# or

transpile_file(
  in_path='<path to your R file>.r', 
  out_path='<Path to generated Python file>.py'
)

🛠 How it works

Rhyton uses tree-sitter under the hood, to compute AST (Abstract Syntax Tree), after that it converts it to new AST that is valid for Python. After that it generates a code, using ast module and astor
