+# python-quickjs-runtime
+
+A lightweight, high-performance Python binding for the [QuickJS](https://bellard.org/quickjs/) Javascript Engine.
+
+This library allows you to execute JavaScript code within your Python applications, providing seamless interoperability between Python and JavaScript.
+
+## Features
+
+*   **Evaluate JavaScript**: Run JS code strings or files directly from Python.
+*   **Data Exchange**: Pass `int`, `float`, `str`, `bool`, and `None` between Python and JS.
+*   **Python Callbacks**: Call Python functions directly from JavaScript.
+*   **Console Support**: Built-in `console.log`, `console.error`, etc., mapped to Python's stdout/stderr.
+*   **REPL**: Includes a simple interactive shell for testing JS snippets.
+*   **Easy Build**: Uses `zigcc-build` for reliable cross-platform compilation.
+
+## Installation
+
+You can install the package from the source:
+
+```bash
+pip install .
+```
+
+## Usage
+
+### Basic Evaluation
+
+```python
+from quickjs_runtime import Context
+
+ctx = Context()
+
+# Evaluate simple expressions
+result = ctx.eval("1 + 2")
+print(result)  # 3
+
+# Evaluate strings
+greeting = ctx.eval("'Hello ' + 'World'")
+print(greeting)  # "Hello World"
+```
+
+### Interoperability
+
+You can set global variables in the JavaScript context and retrieve results.
+
+```python
+ctx = Context()
+
+# Set variables
+ctx.set("x", 10)
+ctx.set("y", 20)
+
+# Use them in JS
+result = ctx.eval("x * y")
+print(result)  # 200
+```
+
+### Calling Python from JavaScript
+
+You can pass Python functions to the JavaScript context.
+
+```python
+def add(a, b):
+    return a + b
+
+ctx = Context()
+ctx.set("py_add", add)
+
+# Call the Python function from JS
+result = ctx.eval("py_add(5, 7)")
+print(result)  # 12
+```
+
+### Evaluating Files
+
+```python
+ctx = Context()
+# Assuming 'script.js' exists
+result = ctx.eval_file("script.js")
+```
+
+### Console Output
+
+The `console` object is available in the JS context and redirects to Python's standard output/error.
+
+```python
+ctx = Context()
+ctx.eval("console.log('This goes to stdout')")
+ctx.eval("console.error('This goes to stderr')")
+```
+
+## REPL
+
+The package includes a simple REPL (Read-Eval-Print Loop).
+
+```bash
+python -m quickjs_runtime
+```
+
+## Development
+
+This project uses `zigcc-build` to compile the C extensions. This ensures a consistent build environment without needing to install system-wide C compilers.
+
+To build and install locally:
+
+```bash
+python -m build
+pip install dist/*.whl
+```
+
+To run tests:
+
+```bash
+pytest
+```
