Finally, you can use await in evaluate expression 💪

Hi there 👋

Can you help me learn Haskell?

My OOP mind struggles every time I attempt to learn it 😢

fibs = 0 : 1 : zipWith (+) fibs (tail fibs)

About me

I am a Software Engineer who mostly works with Python but used to work with C/C++ and Java a long time ago. Hope one day I will be able to understand Haskell (I have a dream to learn functional programming).

PEP 505 None-aware operators is a feature that I miss the most in Python.

I?.really?.want?.this?.feature ?? "Or not?"

Things done by me

FastAPI related

If you are using FastAPI and use function return type annotation as response_model you should know - I am the one who implemented it 😄 (FastAPI #1436).

from fastapi import FastAPI
from pydantic import BaseModel

app = FastAPI(title="Bio")


class Bio(BaseModel):
    name: str
    education: str
    languages: set[str]


@app.get("/me")
async def get_bio() -> Bio:
    return Bio(
        name="Yurii",
        education="Master's degree in Computer Engineering",
        languages={"Ukrainian", "English", "Polish", "German (a bit)"},
    )

Also, I have created fastapi-pagination package that helps you to paginate things (obviously) using FastAPI 📖. Another thing that I currently work on is fastapi-filters package. Hope one day it will be useful for someone as fastapi-pagination is 🍸.

Python related

I have several contributions to Python itself (commits). The most interesting one is (#23316 Store func annotations as a tuple). This optimization reduces memory footprint and improves performance of loading modules having many func annotations.

>>> sys.getsizeof({"a":"int","b":"int","return":"int"})
232
>>> sys.getsizeof(("a","int","b","int","return","int"))
88

The tuple is converted into dict on the fly when func.__annotations__ is accessed first.

PyCharm related

I have created a plugin (pycharm-evaluate-async-code) for PyCharm that helps you evaluate async code the using Evaluate Expression window. This is really useful when you are debugging your code and want to check some async stuff. I guess it's my favorite project that I have ever done (because I used it every day and it really saved me a lot of time).

Support event loops other than asyncio

I got an error message saying that uvloop isn't supported, and that it only supports programs running in asyncio. I was debugging a fastAPI service, so I believe making the plugin more extensible would be a valuable feature.

2021.1 Doesn't work {SyntaxError}'await' outside function

Hi @devova,

I saw your review of this plugin https://plugins.jetbrains.com/plugin/14476-evaluate-async-code/reviews#review=53951

Could you please share more details? Maybe I will be able to fix this issue.

Doesn't work

RuntimeError: this event loop is already running.

not working when using fastapi

I'm really sorry, but due to my poor English, I can only use translation software.

When I started the FASTAPI service using the debugger method, the front-end sent the request successfully with a breakpoint, but still unable to execute asynchronous code

strange behaviour in aiogram library

See this bug report aiogram/aiogram#496
After disabling your plugin, it started working fine.
I don't know whether the problem is your plugin.
I just thought that you might want to take a look.

Don't work with docker-compose interpreter.

When start app using docker interpreter and stop in somebreakpoint there is SyntaxError "await outside function"

Project configuration:

Code for test:

import uvicorn
from fastapi import FastAPI

app = FastAPI()


@app.get("/test2/")
async def test_async():
    return {}


if __name__ == '__main__':
    uvicorn.run(app, port=5000, host='0.0.0.0')

Great plugin , but doesn't work anymore in pycharm 2021.3.1

Basically if you try and await in a console you get SyntaxError: 'await' outside function -

I use a virtual environment - used to work beautifully before upgrading pycharm . I am also on the latest version of the plugin 1.19.

if it helps. the stacktrace looks like this:-

import asyncio
await asyncio.sleep(1)

add support for js/nodejs

could you please check the possibility of adding support for evaluating async js code

How does it works?

After install this plugin (IDE was restarted) in evaluate expression still getting error: SyntaxError: 'await' outside function.
Could you explain how it should work?

SyntaxError: invalid syntax

Hello
The question in the title, I would really appreciate an answer

Any plan to support trio?

If you could point me in the right direction I might be able to implement this myself and add a PR.

Thanks in advance

When debugging code, normal code breaks can lead to different runtime results

First of all, I am very sorry, I am not completely sure that this bug is caused by this plug-in, first submit an issue, record the problem situation

When I was using tortoise-orm, debugging the code, I found that line breaks will affect the results of code execution, the following is a GIF recorded when the problem occurs in the project

The plugin does not work in debug console

Hello,

In the plugin description, you wrote:

Finally, you can use async/await during debugging your code. Currently supports: evaluate an expression, conditional breakpoints, console window.

However, I'm trying to use your plugin in debug console but it does not work. I'm getting the errors.

Before evaluation in "Evaluate expression" window:

>>> await foo()
  File "<input>", line 1
SyntaxError: 'await' outside function

After evaluation in "Evaluate expression" window:

>>> await foo()
  File "<input>", line 1
    __import('sys')__.__async_eval__('await foo()\n', globals(), locals())
                   ^
SyntaxError: invalid syntax

My test code:

import asyncio

async def foo():
    print('hello')

async def main():
    await foo()   # <-- the breakpoint is here

if __name__ == '__main__':
    asyncio.run(main())

I'm using Python 3.8/3.9 and PyCharm 2020.3, Evaluate async code 1.6

Plug-in version

The plugin is not being applied automatically

The plugin does not work in debug console (issue: await outside function) automatically. To make it work one has to click "evaluate expression" and put some await ... as the expression. After that action, the await in the console works OK (i.e. there is no await outside function).

Plugin version: 1.2.0

Add unit tests

I must add unit tests to cover most of the async code evaluation cases

variables redecleared inside async with block are missing

Variables redecleared inside async with block are not appearing in the debug window. New variables are fine.

awaiting a function crashes the debugger

As soon as I set a breakpoint and evaluate e.g. await asyncio.sleep(1), I get the following error log and from then on stepping does not work anymore.
