contextlib-ext - extensions for contextlib

contextlib-ext is a complimentary library for contextlib, it provides a following helpers:

suppress as a decorator

suppress can be used as a decorator

from contextlib_ext import suppress

@suppress(Exception)
def phony_func():
    raise ValueError

phony_func()
print("No exceptions")

@asynccontextmanager creates decorator

@asynccontextmanager creates context manager that can be used as a decorator (contextlib.contextmanager already supports it)

from contextlib_ext import asynccontextmanager

@asynccontextmanager
async def mymanager():
    yield

# The same as contextlib.asynccontextmanager
async with mymanager():
    pass

# This also works
@mymanager
async def myfunc():
    pass

async_suppress

async_suppress - the same as suppress, but async

from contextlib_ext import async_suppress

try:
  async with async_suppress(Exception):
      raise ValueError
except Exception:
  assert False  # never happens
else:
  print("No exceptions")

# Works as decorator too

@async_suppress(Exception)
async def phony_func():
    raise ValueError

phony_func()
print("No exceptions")
