Common utility functions for python code that interacts with Ethereum
Read the [documentation](https://eth-utils.readthedocs.io/).
View the [change log](https://eth-utils.readthedocs.io/en/latest/release_notes.html).
## Installation
```sh
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](https://github.com/ethereum/snake-charmers-tactical-manual)
for information on how we do:
- Testing
- Pull Requests
- Documentation
We use [pre-commit](https://pre-commit.com/) 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:
```sh
git clone git@github.com: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.
```sh
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:
```sh
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"`
