  If you have problems with installing `pytest` package you can simply run

```
# For MacOS/Linux
python -m unittest -v

# For Windows
py -m unittest -v
```

## Client

Core client library has sync and async request modes.
Some core methods are available only in async request mode and
this mode is more prefferable, so python client created with async core requests by default.

Create client

```python
from tonclient.types import ClientConfig
from tonclient.client import TonClient

client = TonClient(config=ClientConfig())

# If you need sync core requests for some reason
client_sync_core = TonClient(config=ClientConfig(), is_core_async=False)
```

Client created with default config

```python
from tonclient.types import NetworkConfig, CryptoConfig, AbiConfig, BocConfig, ProofsConfig, ClientConfig


# Default network config is below.
# `None` attributes are filled by core with defaults values:
#     `server_address=''`
#     `endpoints=[]`
#     `network_retries_count=5` (DEPRECATED)
#     `message_retries_count=5`
#     `max_reconnect_timeout=120000`
#     `message_processing_timeout=40000`
#     `wait_for_timeout=40000`
#     `out_of_sync_threshold=15000`
#     `sending_endpoint_count=2`
#     `reconnect_timeout=` (DEPRECATED)
#     `access_key=''`
#     `latency_detection_interval=60000`
#     `max_latency=60000`
#     `query_timeout=60000`
#     `queries_protocol='HTTP'`
network = NetworkConfig(
    server_address='http://localhost', endpoints=None, network_retries_count=None,
    message_retries_count=None, message_processing_timeout=None, reconnect_timeout=None,
    wait_for_timeout=None, out_of_sync_threshold=None, sending_endpoint_count=None,
    access_key=None, max_reconnect_timeout=None, latency_detection_interval=None,
    max_latency=None, query_timeout=None, queries_protocol=None)

# Default crypto config is below.
# `None` attributes are filled by core with defaults values:
#     `mnemonic_dictionary=1`
#     `mnemonic_word_count=12`
#     `hdkey_derivation_path="m/44'/396'/0'/0/0"`
crypto = CryptoConfig(
    mnemonic_dictionary=None, mnemonic_word_count=None, hdkey_derivation_path=None)

# Default abi config is below.
# `None` attributes are filled by core with defaults values:
#     `workchain=0`
#     `message_expiration_timeout=40000`
#     `message_expiration_timeout_grow_factor=1.5`
abi = AbiConfig(
    workchain=None, message_expiration_timeout=None,
    message_expiration_timeout_grow_factor=None)

# Default boc config is below.
# `None` attributes are filled by core with defaults values:
#     `cache_max_size=10000` (10MB)
boc = BocConfig(cache_max_size=None)

# Default proofs config is below.
# `None` attributes are filled by core with defaults values:
#     `cache_in_local_storage=True`
proofs = ProofsConfig(cache_in_local_storage=None)

# Then `ClientConfig` is created
config = ClientConfig(network=network, crypto=crypto, abi=abi, boc=boc, proofs=proofs, local_storage_path=None)
```

You can override initial config while creating a client

```python
from tonclient.types import ClientConfig
from tonclient.client import TonClient, DEVNET_BASE_URLS

config = ClientConfig()
config.network.endpoints = DEVNET_BASE_URLS
config.abi.message_expiration_timeout = 30000

client = TonClient(config=config)
version = client.version()
```

Client contains all core modules and its methods.
You can get full list of modules and methods here:
https://github.com/tonlabs/TON-SDK/blob/master/docs/modules.md
Module method called by template `client.[module].[method]`

```python
from tonclient.types import ClientConfig, ParamsOfParse
from tonclient.client import TonClient, DEVNET_BASE_URLS

config = ClientConfig()
config.network.endpoints = DEVNET_BASE_URLS
client = TonClient(config=config)

# Generate random signing keys
keypair = client.crypto.generate_random_sign_keys()

# Parse account
parse_params = ParamsOfParse(boc='Account base64 BOC')
result = client.boc.parse_account(params=parse_params)
```

You always can get information about method and its arguments in method docstring.

### Methods with callbacks

Some library methods accept `callback` argument to pass additional data to it.
E.g. `net.subscribe_collection`

```python
import time
from datetime import datetime

from tonclient.errors import TonException
from tonclient.types import ClientConfig, ClientError, SubscriptionResponseType, \
    ParamsOfSubscribeCollection, ResultOfSubscription
from tonclient.client import DEVNET_BASE_URLS, TonClient


config = ClientConfig()
config.network.endpoints = DEVNET_BASE_URLS
client = TonClient(config=config)


def __callback(response_data, response_type, loop):
    """
    `loop` in args is just for example.
    It will have value only with `asyncio` and may be replaced by `_` or `*args`
    in synchronous requests
    """
    if response_type == SubscriptionResponseType.OK:
        result = ResultOfSubscription(**response_data)
        results.append(result.result)
    if response_type == SubscriptionResponseType.ERROR:
        raise TonException(error=ClientError(**response_data))

results = []
now = int(datetime.now().timestamp())
q_params = ParamsOfSubscribeCollection(collection='messages', result='created_at', filter={'created_at': {'gt': now}})
subscription = client.net.subscribe_collection(params=q_params, callback=__callback)

while True:
    if len(results) > 0 or int(datetime.now().timestamp()) > now + 10:
        client.net.unsubscribe(params=subscription)
        break
    time.sleep(1)
```

`tonclient/test/test_crypto.py`, `tonclient/test/test_debot.py` to get more examples.

## Client and asyncio

```python
from tonclient.types import ClientConfig
from tonclient.client import TonClient, DEVNET_BASE_URLS

# Create client with `is_async=True` argument.
config = ClientConfig()
config.network.endpoints = DEVNET_BASE_URLS
client = TonClient(config=config, is_async=True)

# Get version (simple method with result)
version = await client.version()
```

Please, dig in `tonclient/test/test_async.py` to get more info
