Development Environment Setup
You can set up your dev environment with:
git clone git@github.com:ethereum/asyncio-cancel-token.git
cd asyncio-cancel-token
virtualenv -p python3 venv
. venv/bin/activate
pip install -e .[dev]

Testing Setup
During development, you might like to have tests run on every file save.
Show flake8 errors on file change:
# Test flake8
when-changed -v -s -r -1 cancel_token/ tests/ -c "clear; flake8 cancel_token tests && echo 'flake8 success' || echo 'error'"
Run multi-process tests in one command, but without color:
# in the project root:
pytest --numprocesses=4 --looponfail --maxfail=1
# the same thing, succinctly:
pytest -n 4 -f --maxfail=1
Run in one thread, with color and desktop notifications:
cd venv
ptw --onfail "notify-send -t 5000 'Test failure ⚠⚠⚠⚠⚠' 'python 3 test on asyncio-cancel-token failed'" ../tests ../cancel_token

Release setup
For Debian-like systems:
apt install pandoc
To release a new version:
make release bump=$$VERSION_PART_TO_BUMP$$

How to bumpversion
The version format for this repo is {major}.{minor}.{patch} for
stable, and {major}.{minor}.{patch}-{stage}.{devnum} for unstable
(stage can be alpha or beta).
To issue the next version in line, specify which part to bump, like
make release bump=minor or make release bump=devnum.
If you are in a beta version, make release bump=stage will switch to
a stable.
To issue an unstable version when the current version is stable, specify
the new version explicitly, like
make release bump="--new-version 4.0.0-alpha.1 devnum"
