## Features

Squid-py include the methods to make easy the connection with contracts deployed in different networks.
This repository include also the methods to encrypt and decrypt information.

## Prerequisites

You should have running a instance of BigchainDB and ganache-cli.
You can start running the docker-compose in the docker directory:

## Quick-start

When you want to interact with the contracts you have to instantiate this class:

```python
from squid_py.ocean_contracts import OceanContractsWrapper
ocean = OceanContractsWrapper(host='http://localhost', port=8545, config_path='config.ini')
ocean.init_contracts()
```
If you do not pass the config_path the wrapper will use the default values.
After that you have to init the contracts. And you can start to use the methods in the different contracts.

You will find as well two methods that allow you to register and consume an asset.
```python
from squid_py.consumer import register, consume
register(publisher_account=ocean.web3.eth.accounts[1],
provider_account=ocean.web3.eth.accounts[0],
price=10,
ocean_contracts_wrapper=ocean,
json_metadata=json_consume
)
consume(resource=resouce_id,
consumer_account=ocean.web3.eth.accounts[1],
provider_account=ocean.web3.eth.accounts[0],
ocean_contracts_wrapper=ocean,
json_metadata=json_request_consume)

```

## Code style

The information about code style in python is documented in this two links [python-developer-guide](https://github.com/oceanprotocol/dev-ocean/blob/master/doc/development/python-developer-guide.md)
and [python-style-guide](https://github.com/oceanprotocol/dev-ocean/blob/master/doc/development/python-style-guide.md).

## Testing

Automatic tests are setup via Travis, executing `tox`.
Our test use pytest framework.

## New Version

The `bumpversion.sh` script helps to bump the project version. You can execute the script using as first argument {major|minor|patch} to bump accordingly the version.
