## Description

# Python Tree-sitter

[![CI][ci]](https://github.com/tree-sitter/py-tree-sitter/actions/workflows/ci.yml)

This module provides Python bindings to the [tree-sitter] parsing library.

## Installation

The package has no library dependencies and provides pre-compiled wheels for all major platforms.

> [!NOTE]
> If your platform is not currently supported, please submit an [issue] on GitHub.

```sh
pip install tree-sitter
```

## Usage

### Setup

#### Install languages

Tree-sitter language implementations also provide pre-compiled binary wheels.
Let's take [Python][tree-sitter-python] as an example.

```sh
pip install tree-sitter-python
```

Then, you can load it as a `Language` object:

```python
import tree_sitter_python as tspython
from tree_sitter import Language, Parser

PY_LANGUAGE = Language(tspython.language())
```

### Basic parsing

Create a `Parser` and configure it to use a language:

```python
parser = Parser(PY_LANGUAGE)
```

Parse some source code:

```python
tree = parser.parse(
    bytes(
        """
def foo():
    if bar:
        baz()
""",...

## AI interpretation — verify before relying

Python bindings to the tree-sitter incremental parsing library, enabling syntax tree construction and traversal for code analysis across multiple programming languages.

Verdict: Stable, actively maintained parser binding with zero known vulnerabilities and broad platform coverage. No runtime dependencies and permissive licensing make it suitable for production use. Medium install friction is manageable via pre-built wheels across major platforms.
