# EzSlack

EzSlack is a Python framework wrapping [Bolt for Python](https://github.com/slackapi/bolt-python) to provide useful utilities.

- Encapsule parsing low-level information
- Provide `Handler` class to improve cohesion

## Get Started

```python
from ezslack import App

# Running over HTTP
app = App(token=SLACK_BOT_TOKEN, signing_secret=SLACK_SIGNING_SECRET)
app.start(PORT)

# Running in Socket Mode
app = App(token=SLACK_BOT_TOKEN)
app.start_socket_mode(SLACK_APP_TOKEN)
```

## Handler

Whenever subclass of [`Handler`](ezslack/handler/handler.py) is defined, handler methods are registered in [`REGISTRIES`](ezslack/handler/registry.py#L33). String arguments in handler decorator are automatically converted into regex pattern with anchors. Matched groups are passed to arguments and keyword arguments whether they are named.

```python
from ezslack import Handler, message

class MyHandler(Handler):
    @message("hello", "hi")
    def greet(self):
        self.ack()
        self.say(
            f"Nice to meet you <@{self.user_id}>",
            thread_ts=self.thread_ts,
        )

    @message(r"(?P<first>\w+)(?P<op>[+*])(?P<second>\w+)")
    def calculate(self, first, second, op):
        if op == "+":
            result = int(first) + int(second)
        else:
            result = int(first) * int(second)
        self.say(f"Result: {result}", thread_ts=self.thread_ts)
```

## Supported features

Requests supported: `ACTION`, `MESSAGE`, `VIEW_CLOSED`, `VIEW_SUBMISSION`

Each request has an id such as `action_id`, `message.text`, `callback_id`. When a request id matches handling method's regex pattern, handler is instantiated with the following context fields, then call the method.
