tree-sitter-ipython

A tree-sitter grammar for IPython/Jupyter that extends tree-sitter-python to support magic commands and shell escapes.

Features

- Line Magics (%): %matplotlib inline, %timeit x = 1, %pwd
- Cell Magics (%%): %%time, %%bash, %%writefile test.py
- Shell Escapes (!): !pip install pandas, !ls -la
- Full Python syntax support (inherited from tree-sitter-python)

Installation

``bash
npm install tree-sitter-ipython
`

Usage

`javascript
const Parser = require("tree-sitter");
const IPython = require("tree-sitter-ipython");

const parser = new Parser();
parser.setLanguage(IPython);

const code =
%matplotlib inline
import pandas as pd
!pip install numpy
%%time
x = sum(range(1000))
;

const tree = parser.parse(code);
console.log(tree.rootNode.toString());
