# WOWlet WS Client

Sample Python asyncio websocket client for communicating with
wowlet running in "background mode" via websockets.

This library was made in a few hours, so it's not complete, and should
serve as an example and PoC.

## Example

First, start [wowlet](https://git.wownero.com/wowlet/wowlet/):

  ./wowlet --background 127.0.0.1:42069

Then run the following script, it will:

1. Open a wallet
2. Request a receiving address listing
3. Run forever

```python
import asyncio

from wowlet_ws_client.client import WowletWSClient


wowlet = WowletWSClient(
    host="127.0.0.1", port=1234, password="sekrit", debug=True)


@wowlet.event("passwordIncorrect")
async def on_password_incorrect(data):
    print(data)


@wowlet.event("passwordSuccess")
async def on_password_success(data):
    print(data)


@wowlet.event("walletList")
async def on_wallet_list(data):
    print("wallet listing received")
    print(data)


@wowlet.event("addressList")
async def on_address_list(data):
    print("address listing received")
    print(data)


@wowlet.event("transactionHistory")
async def on_transaction_history(data):
    print(data)


@wowlet.event("addressBook")
async def on_address_book(data):
    print(data)


@wowlet.event("synchronized")
async def on_synchronized(data):
    # called when the wallet is synchronized with the network
    print(data)


@wowlet.event("transactionCommitted")
async def on_transaction_commited(data):
    # when a transaction was sent
    print(data)


async def main():
    await wowlet.connect()
    await asyncio.sleep(3)
    await wowlet.authenticate()
    await asyncio.sleep(3)

    await wowlet.open_wallet("/home/user/Wownero/wallets/wstest.keys", "test")

    await asyncio.sleep(3)
    await wowlet.address_list(0, 0)

    # hack to keep the script running
    while True:
        await asyncio.sleep(1)

loop = asyncio.get_event_loop()
loop.run_until_complete(main())
```

## Creating a wallet

Default directory = wowlet's default wallet directory

```python
@wowlet.event("walletCreated")
async def on_wallet_created(data):
    print(data)

@wowlet.event("walletCreatedError")
async def on_wallet_created_error(data):
    print("error")
    print(data)

await wowlet.create_wallet("cool_wallet", password="sekrit")
```

## Creating a transaction

```python
address = "WW2cyFaAu4NSpZdpEP3egWcK99QqU8afJEpfZW1HNxofB9sH86Nir5pes7ofwAE3ZWVNdgxFrWeSiSiSLumSeZ7538zCXb6gp"
await wowlet.send_transaction(
    address=address,
    amount=2,
    description="test transaction from Python")
```

## QR

This library can also generate QR codes because why not.

```python
import aiofiles
from wowlet_ws_client.qr import qr_png

addr = "some_address_here"
qr_image = qr_png(addr)

async with aiofiles.open('output.png', mode="wb") as f:
    await f.write(qr_image.getbuffer())
```
