# inherit-docstring

A python decorator to inherit docstring.
Easily inherit docstrings from parent classes with `@inherit_docstring` decorator, designed specifically for [the NumPy docstring style](https://numpydoc.readthedocs.io/en/latest/format.html).
Use inherit-docstring to streamline your documentation process, ensuring consistency and reducing redundancy!
## Features
- Automatic Inheritance: Just add the `@inherit_docstring` decorator, and the child class will seamlessly inherit the parent's class and function docstrings.
- Structured Sections: Docstrings are broken into sections like `Attributes`, `Notes`, etc. Each section is denoted by its title followed by `---`.
- Header Section: An exclusive `Header` section is introduced for the starting portion of the docstring without a specific title.
- Parameter Sections: Certain sections are treated as parameter sections where the content is interpreted as parameter explanations. They include:
- Attributes
- Parameters
- Returns
- Yields
- Receives
- Raises
- Warns
- Warnings
- Deprecated sections: Sections starting with `.. deprecated:: x.y.z`, is parsed as deprecated sections.
## Behavior
- If a child class function lacks a docstring, it inherits the parent's docstring verbatim.
- For functions where both parent and child have docstrings:
- Section-wise Merge: Docstrings are combined on a section-by-section basis.
- Parameter-wise Merge: Within parameter sections, docstrings are combined parameter by parameter.
- Child Priority: When both parent and child provide docstrings for the same function or parameter, the child's version is prioritized.
## Requirement
- Python >=3.9
- Poetry (For development)
## Installation
By pip:
```
$ pip3 install inherit-docstring
```
## Usage
Add `inherit_docstring` decorator to the inherited class:
```
from inherit_docstring import inherit_docstring
class Parent:
"""Parent class.
This is an explanation.
Attributes
----------
name: str
The name of
the parent.
age:
The age. w/o type.
Notes
-----
This is parent's note.
"""
name: str = 'parent'
age: int = 40
def func1(self, param1: int, param2: int) -> int:
"""Parent's func1.
Parameters
----------
param1: int
First input.
param2: int
Second input.
Returns
-------
ret: int
param1 + param2
"""
return param1 + param2
def func2(self) -> None:
"""Parent's func2.
Returns
-------
ret: str
something
"""
return 'Something'
@inherit_docstring
class Child(Parent):
"""Child class.
Attributes
----------
sex: str
Additional attributes.
girl or boy.
"""
sex: str = "boy"
def func1(self, param1: int, param2: int) -> int:
"""Child's func1.
Returns
-------
ret: int
param1 - param2
"""
return param1 - param2
```
Child class' help will be:
```
class Child(Parent)
| Child class.
|
| Attributes
| ----------
| name: str
| The name of
| the parent.
| age:
| The age. w/o type.
| sex: str
| Additional attributes.
| girl or boy.
|
| Notes
| -----
| This is parent's note.
|
| Method resolution order:
| Child
| Parent
| builtins.object
|
| Methods defined here:
|
| func1(self, param1: int, param2: int) -> int
| Child's func1.
|
| Parameters
| ----------
| param1: int
| First input.
| param2: int
| Second input.
|
| Returns
| -------
| ret: int
| param1 - param2
```
