Installation

python -m pip install eth-utils

Developer Setup

If you would like to hack on eth-utils, please check out the Snake Charmers Tactical Manual for information on how we do:

• Testing
• Pull Requests
• Documentation

We use pre-commit to maintain consistent code style. Once installed, it will run automatically with every commit. You can also run it manually with make lint. If you need to make a commit that skips the pre-commit checks, you can do so with git commit --no-verify.

Development Environment Setup

You can set up your dev environment with:

git clone [e-mail]:ethereum/eth-utils.git
cd eth-utils
virtualenv -p python3 venv
. venv/bin/activate
python -m pip install -e ".[dev]"
pre-commit install

Update Networks

The list of networks resides in the JSON file under eth_utils/__json/eth_networks.json. This file is used to initialize Networks, which can be used to obtain network information with a chain ID.

Run the script to update the JSON file with the response from the remote list.

python update_networks.py

If there are new networks they will appear in the JSON file. After checking the updates, open a PR to make them available in a new release.

Release setup

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. This is typically done from the main branch, except when releasing a beta (in which case the beta is released from main, and the previous stable branch is released from said branch).

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"
