# flake8-scream

A [flake8](https://flake8.pycqa.org/en/latest/index.html) plugin that helps you scream your code.

## Rules

* [`SCR119`](https://github.com/MartinThoma/flake8-simplify/issues/37) ![](https://shields.io/badge/-legacyfix-inactive): Use dataclasses for data containers ([example](#SCR119))

* [`SCR902`](https://github.com/MartinThoma/flake8-simplify/issues/125): Use keyword-argument instead of magic boolean ([example](#SCR902))

* `SCR903`: Use keyword-argument instead of magic number ([example](#SCR903))

## Disabling Rules

You might have good reasons to

[ignore some flake8 rules](https://flake8.pycqa.org/en/3.1.1/user/ignoring-errors.html).

To do that, use the standard Flake8 configuration. For example, within the `setup.cfg` file:

```python

[flake8]

ignore = SCR106, SCR113, SCR119, SCR9

```

## Examples

### SCR119

Dataclasses were introduced with [PEP 557](https://www.python.org/dev/peps/pep-0557/)

in Python 3.7. The main reason not to use dataclasses is to support legacy Python versions.

Dataclasses create a lot of the boilerplate code for you:

* `__init__`

* `__eq__`

* `__hash__`

* `__str__`

* `__repr__`

A lot of projects use them:

* [black](https://github.com/psf/black/blob/master/src/black/__init__.py#L1472)

### SCR902

```python

# Bad

foo(False)

bar(True)

# Good

foo(verbose=False)

bar(enable_magic=True)

```

The false-positives that are currentl not possible to fix are in positional-only

arguments. There is no way to determine in the AST given by Flake8 if a function

has positional-only arguments.

### SCR903

```python

# Bad

foo(42, 1.234)

# Good

foo(the_answer=42, flux_compensation=1.234)

```

The false-positives that are currentl not possible to fix are in positional-only

arguments. There is no way to determine in the AST given by Flake8 if a function

has positional-only arguments.
