Developer setup
If you would like to hack on web3.py, set up your dev environment with:
sudo apt-get install libssl-dev
# ^ This is for Debian-like systems. TODO: Add more platforms
git clone git@github.com:pipermerriam/web3.py.git
cd web3.py
virtualenv venv
. venv/bin/activate
pip install -r requirements-dev.txt
pip install -e .For different environments, you can set up multiple virtualenvs, like:
Python 2
virtualenv -p python2 venvpy2
. venvpy2/bin/activate
pip install -r requirements-dev.txt
pip install -e .Docs
virtualenv venvdocs
. venvdocs/bin/activate
pip install -r requirements-dev.txt
pip install -e .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 -r web3/ tests/ -c "clear; git diff HEAD^ | flake8 --diff"You can use pytest-watch, running one for every python environment:
pip install pytest-watch
cd venv
ptw --onfail "notify-send -t 5000 'Test failure ⚠⚠⚠⚠⚠' 'python 3 test on web3.py failed'" ../tests ../web3
#in a new console
cd venvpy2
ptw --onfail "notify-send -t 5000 'Test failure ⚠⚠⚠⚠⚠' 'python 2 test on web3.py failed'" ../tests ../web3Or, you can run multi-process tests in one command, but without color:
# in the project root:
py.test --numprocesses=4 --looponfail --maxfail=1
# the same thing, succinctly:
pytest -n 4 -f --maxfail=1Release 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"
