# safepath

A Python library providing null-safe attribute and key access through a simple chaining API.

## Installation

```bash
pip install safepath
```

## Usage

```python
from safepath import sp

# Basic usage
data = {"user": {"name": "John"}}
name = sp(data)["user"]["name"]()  # Returns "John"
missing = sp(data)["user"]["age"]()  # Returns None

# Object attribute access
class User:
    def __init__(self):
        self.name = "John"
        self.address = None

user = User()
name = sp(user).name()  # Returns "John"
city = sp(user).address.city()  # Returns None

# Chaining
data = {
    "users": [
        {"profile": {"address": {"city": "New York"}}}
    ]
}
city = sp(data)["users"][0]["profile"]["address"]["city"]()  # Returns "New York"
missing = sp(data)["users"][1]["profile"]["address"]["city"]()  # Returns None
```

Sign Ethereum transactions and messages with local private keys

Read more in the [documentation on ReadTheDocs](https://eth-account.readthedocs.io/). [View the change log](https://eth-account.readthedocs.io/en/latest/release_notes.html).

## Quickstart

```sh
python -m pip install eth-account
```

## Developer Setup

If you would like to hack on eth-account, 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-account.git
cd eth-account
virtualenv -p python3 venv
. venv/bin/activate
python -m pip install -e ".[dev]"
pre-commit install
```

To run the integration test cases, you need to install node and the custom cli tool as follows:

```sh
apt-get install -y nodejs  # As sudo
./tests/integration/js-scripts/setup_node_v20.sh  # As sudo
cd tests/integration/js-scripts
npm install -g .  # As sudo
```

### 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"`
