Quickstart

Development Environment Setup

You can set up your dev environment with:

git clone git@github.com:ethereum/eth-typing.git
cd eth-typing
virtualenv -p python3 venv
. venv/bin/activate
python -m pip install -e ".[dev]"

Network ChainIds

A list of ChainId constants reside in the eth-typing/networks.py file. This list should be kept in sync with the network list available on chainid.network.

To keep the list up to date, run the following command:

python update_network_chain_ids.py

This will remove the original networks file and output a new file with the new networks added.

Check that the output file is correct and that constants are defined as expected. If the shortName contains special characters it may not work as a constant variable name. The script should be updated to transform names into valid constants as new cases occur.

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 master branch, except when releasing a beta (in which case the beta is released from master, 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"
