Asynchronous console and interfaces for asyncio
Project description
Asynchronous console and interfaces for asyncio
aioconsole provides:
asynchronous equivalents to input, print, exec and code.interact
an interactive loop running the asynchronous python console
a way to customize and run command line interface using argparse
stream support to serve interfaces instead of using standard streams
the apython script to access asyncio code at runtime without modifying the sources
Requirements
Python >= 3.6
Installation
aioconsole is available on PyPI and GitHub. Both of the following commands install the aioconsole package and the apython script.
$ pip3 install aioconsole # from PyPI
$ python3 setup.py install # or from the sources
$ apython -h
usage: apython [-h] [--serve [HOST:] PORT] [--no-readline]
[--banner BANNER] [--locals LOCALS]
[-m MODULE | FILE] ...
Run the given python file or module with a modified asyncio policy replacing
the default event loop with an interactive loop. If no argument is given, it
simply runs an asynchronous python console.
positional arguments:
FILE python file to run
ARGS extra arguments
optional arguments:
-h, --help show this help message and exit
--serve [HOST:] PORT, -s [HOST:] PORT
serve a console on the given interface instead
--no-readline force readline disabling
--banner BANNER provide a custom banner
--locals LOCALS provide custom locals as a dictionary
-m MODULE run a python moduleSimple usage
The following example demonstrates the use of await inside the console:

---
This console is running in an asyncio event loop.
It allows you to wait for coroutines using the 'await' syntax.
Try: await asyncio.sleep(1, result=3, loop=loop)
--->>> await asyncio.sleep(1, result=3)
# Wait one second...

Limitations
The python console exposed by aioconsole is quite limited compared to modern consoles such as IPython or ptpython. Luckily, those projects gained greater asyncio support over the years. In particular, the following use cases overlap with aioconsole capabilities:
