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.
.. sourcecode:: console
$ 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 module
Simple usage
------------
The following example demonstrates the use of ``await`` inside the console:
.. sourcecode:: console
$ apython
Python 3.5.0 (default, Sep 7 2015, 14:12:03)
[GCC 4.8.4] on linux
Type "help", "copyright", "credits" or "license" for more information.
---
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)
---
.. sourcecode:: python3
>>> await asyncio.sleep(1, result=3)
# Wait one second...
3
>>>
Documentation
-------------
Find more examples in the documentation_ and the `example directory`_.
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:
- `Embedding a ptpython console in an asyncio program <https://github.com/prompt-toolkit/ptpython/blob/master/examples/asyncio-python-embed.py>`_
- `Using the await syntax in an IPython console <https://ipython.readthedocs.io/en/stable/whatsnew/version7.html#autowait-asynchronous-repl>`_
