## Installing<a name="installing"></a>
Require Python >= 3.8, installing from [PyPI repository](https://pypi.org/project/chainlibpy):
```bash
pip install chainlibpy
```
## Usage<a name="usage"></a>
### Generating a wallet<a name="generating-a-wallet"></a>
```python
from chainlibpy import Wallet
# create a wallet
wallet = Wallet.new()
# or you can recover from an mnomic
# mnemonic = "dune car envelope chuckle elbow slight proud fury remove candy uphold puzzle call select sibling sport gadget please want vault glance verb damage gown"
# wallet = Wallet(mnemonic)
print(wallet.private_key)
print(wallet.public_key)
print(wallet.address)
```
### Signing and broadcasting a transaction<a name="signing-and-broadcasting-a-transaction"></a>
Please refer to `example/transaction.py` for how to start a local testnet with `pystarport` and change information below to run the examples successfully.
```diff
# Obtained from {directory_started_pystarport}/data/chainmaind/accounts.json
# To recover one of the genesis account
- MNEMONIC_PHRASE = "first ... last"
+ MNEMONIC_PHRASE = "REMEMBER TO CHANGE"
# Obtained from {directory_started_pystarport}/data/chainmaind/accounts.json
- TO_ADDRESS = "cro...add"
+ TO_ADDRESS = "REMEMBER TO CHANGE"
```
### Interact with mainnet or testnet<a name="interact-with-mainnet-or-testnet"></a>
Please refer to `example/secure_channel_example.py` on how to use secure gRPC channel with server certificate to interact with mainnet or testnet.
## Acknowledgement<a name="acknowledgement"></a>
Thanks to [cosmospy](https://github.com/hukkinj1/cosmospy) for the following:
- referenced the packages to sign transaction and create hd wallet
- python lint config file
- use same sign method
Thanks to [eth-utils](https://github.com/ethereum/eth-utils) for the following:
- Conversion of different units without facing precision issues in Python
## Development<a name="development"></a>
### Set up development environment<a name="set-up-development-environment"></a>
Run command below to install dependencies (more about [poetry](https://python-poetry.org/docs/)):
```bash
poetry install
```
### Add pre-commit git hook<a name="add-pre-commit-git-hook"></a>
To set up the git hook scripts, so that [`pre-commit`](https://pre-commit.com/) will run automatically on `git commit`:
```bash
pre-commit install
```
### Generate gRPC code<a name="generate-grpc-code"></a>
```bash
poetry shell
./generated_protos.sh
```
**NOTE:** By default, `master` branch of `cosmos-sdk` is used. Use command below to download a different version:
```bash
./generated_protos.sh -COSMOS_REF=v0.44.5
```
If more generated gRPC code is needed in the future, please add the path to `.proto` file needed here in `generated_protos.sh`:
```diff
# Add .proto files here to generate respective gRPC code
PROTO_FILES="
$COSMOS_SDK_DIR/proto/cosmos/auth/v1beta1/auth.proto
+$COSMOS_SDK_DIR/proto/other.proto
...
```
### Tox<a name="tox"></a>
[Tox](https://tox.wiki/en/latest/) is a tool to automate and standardize testing processes in Python.
For this project, the list of environment that will be run when invoking `tox` command is `py{38,39}`. Hence we need to set up Python 3.8 and 3.9 for this project. Run command below to set a local application-specific Python version (in this case 3.8 and 3.9) with [pyenv](https://github.com/pyenv/pyenv):
```bash
pyenv local 3.8.a 3.9.b
```
**Note:** `a` and `b` are python versions installed on your computer by `pyenv`.
After running command above, a `.python-version` file will be generated, which means python versions inside `.python-version` are presented for this project. Now, running command `tox` should succeed without prompting environment missing error.
Run command below to verify:
```bash
poetry run tox
# or
poetry shell
tox
```
It is also recommended to run `tox` command before pushing a commit.
