Do not break the line! 🚨

## Installation

```bash

pip install flake8-broken-line

```

It is also a valuable part of [`wemake-python-styleguide`](https://github.com/wemake-services/wemake-python-styleguide).

## Code example

Things we check with this plugin:

```python

# String line breaks, use `()` or `"""` instead:

some_string = 'first line\

second line'

# Use a single line, `()`, or new variables instead:

if 1 == 1 and \

    2 == 2:

    print('Do not do that!')

# Do not use for method chaining:

some_object \

  .call_method(param1, param2) \

  .call_other(keyword=value) \

  .finalize()

# Instead use:

some_objects.call_method(

    param1, param2,

).call_other(

    keyword=value

).finalize()

```
