Python package for emulating Python's interactive interpreter in asynchronous contexts.

Installation

Use the package manager pip to install asyncode:

pip install asyncode

Dependencies

  • Python ≥ 3.5 (no CI for Python < 3.8)

Usage

This package's external API consists in two classes, AsyncInteractiveInterpreter and AsyncInteractiveConsole, which subclass respectively code.InteractiveInterpreter and code.InteractiveConsole.

These classes are meant to be used in already running asynchronous contexts. Minimal useful code will need to subclass provided classes to implement specific functions:

import asyncode

class MyAsyncConsole(asyncode.AsyncInteractiveConsole):
    """AsyncInteractiveConsole adapted to running environment"""

    async def write(self, data):
        """Use specific function"""
        await some_output_coroutine(data)

    async def raw_input(self, prompt=""):
        """Use specific functions"""
        if prompt:
            await some_output_coroutine(prompt)

        data = await some_input_coroutine()
        return data


async def run_interpreter():
    """Run an interactive Python interpreter"""
    console = MyAsyncConsole()
    try:
        await console.interact()
    except SystemExit:
        # Do not exit the whole program when sending "exit()" or "quit()"
        await some_output_coroutine("Bye!")
