### The problem
|
|
|
|
Have you ever felt that the `await` syntax in Python was a bit clunky when chaining multiple methods together?
|
|
|
|
```python
|
|
async def on_message(event):
|
|
message = await event.get_message()
|
|
author = await message.get_author()
|
|
await author.send_message("Hello world!")
|
|
```
|
|
|
|
Or even worse:
|
|
|
|
```python
|
|
async def on_message(event):
|
|
(await (await (await event.get_message()).get_author()).send_message("Hello world!"))
|
|
```
|
|
|
|
`async-chain` is here to solve your problem!
|
|
|
|
```python
|
|
async def on_message(event):
|
|
await event.get_message().get_author().send_message("Hello world!")
|
|
```
|
|
|
|
### The solution
|
|
|
|
First, install `async_chain` with your favorite package manager:
|
|
|
|
```console
|
|
$ pip install async_chain
|
|
```
|
|
```console
|
|
$ pipenv install async_chain
|
|
```
|
|
```console
|
|
$ poetry add async_chain
|
|
```
|
|
|
|
Then, add the `@async_chain.method` decorator to any async method you wish to make chainable, and the problem will be
|
|
magically solved!
|
|
|
|
```python
|
|
import async_chain
|
|
|
|
class MyEvent:
|
|
@async_chain.method
|
|
async def get_message(self):
|
|
...
|
|
```
