Please read Pythons asyncio official Documentation for more info. run_async_on_process() runs the code as async on a separate Process. run_async_on_thread() runs the code as async on a separate Thread. get_event_loop() returns the current actual event loop in use, takes no arguments. get_event_loop() is similar to asyncio.get_event_loop()

Arguments:

sync_code: A Callable object, a function or method or whatever callable, anything that you want to run on an async code context, it acts as an auto-wrapper to run your sync code as async.

Keyword Arguments: None.

Returns: Returns whatever the passed argument callable should return, but it await a Future result.

State	OS	Description
✅	Linux	Works Ok
✅	Os X	Works Ok
✅	Windows	Works Ok

Usage Example:

>>> import asyncio, time
>>> from anglerfish import Sync2Async
>>>
>>> def blocking_function():  # This is any common normal blocking function.
>>>     print("Executing Synchronous Blocking code 'time.sleep(1)' as Async!.")
>>>     return time.sleep(1)  # Can be any for, open, with, slow operation, etc.
>>>
>>> async def async_function(sync_code):
>>>     return await Sync2Async.run_async(sync_code)
>>>
>>> async def async_on_process(sync_code):
>>>     return await Sync2Async.run_async_on_process(sync_code)
>>>
>>> async def async_on_thread(sync_code):
>>>     return await Sync2Async.run_async_on_thread(sync_code)
>>>
>>> async_tasks = (asyncio.ensure_future(async_function(blocking_function)),
>>>                asyncio.ensure_future(async_on_process(blocking_function)),
>>>                asyncio.ensure_future(async_on_thread(blocking_function)))
>>> asyncio.get_event_loop().run_until_complete(asyncio.wait(async_tasks))
"Executing Synchronous Blocking code 'time.sleep(1)' as Async!."
"Executing Synchronous Blocking code 'time.sleep(1)' as Async!."
"Executing Synchronous Blocking code 'time.sleep(1)' as Async!."

Install permanently on the system:

pip install anglerfish

Use sudo pip install anglerfish for installing System-wide.
Use python3 examples/basic.py to run an example of all the functionalities.
This project is oriented to Developers, NOT end-users.
Feel free to contact us if you need help integrating Angler on your project.

Why?:

Too much repeated code across my projects, almost all of them doing tha same.
Look into other alternatives like Boltons but they dont solve or improve anything.
Lots of functionalities on Angler are a "Must Have" for modern Apps, like a Logger, etc.
No Dependencies at all, just Python 3 standard library, cross-platform.
Easy to use, KISS philosophy.

Requisites:

Python 3.5+

Config Helper ?

Angler will NOT provide any kind of Configuration/Settings Helpers.
We recommend: https://github.com/ssato/python-anyconfig#python-anyconfig
python-anyconfig only requires Python Standard Library. Works with any kind of config file.

More must have helpers

All these tiny generic awesome helpers, utilities, etc only require Python standard lib.

Coding Style Guide:

Lint, PEP-8, PEP-257, PyLama, iSort must Pass Ok. pip install --upgrade pep8 pep257 pylama isort pytest
If there are any kind of tests, they must pass. No tests is also acceptable, but having tests is better.

Name convention

For names we use: get_*, set_*, check_*, make_*, is_*, has_* and *2*.

Tests

Tests use PyTest. Pull requests to improve tests are welcome.
