`flake8-get-chaining` plugin checks for chained `dict.get` calls and makes sure valid defaults are provided.
## Installation
------------
Install from `pip` with:
```sh
$ pip install flake8-get-chaining
```
It will then automatically be run as part of `flake8`; you can check it has been picked up with:
```sh
$ flake8 --version
5.0.4 (flake8-get-chaining: 0.1.0, mccabe: 0.7.0, pycodestyle: 2.9.1, pyflakes: 2.5.0) CPython 3.10.9 on Linux
```
## List of warnings
------------
**DGC1001**: Missing default argument when chaining dict.get
This warning is emitted when `dict.get` calls are chained, and no default was provided.
_Example_: `my_dict.get("foo").get("bar")`
**DGC1002**: Invalid default argument when chaining dict.get
This warning is emitted when `dict.get` calls are chained, and the default value is
invalid (i.e not a dict nor an identifier)
_Example_: `my_dict.get("foo", "bar").get("baz")`
