|
|
| |
|
|
| ```bash |
| pip install annotated-doc |
| ``` |
|
|
| Or with `uv`: |
|
|
| ```Python |
| uv add annotated-doc |
| ``` |
|
|
| |
|
|
| Import `Doc` and pass a single literal string with the documentation for the specific parameter, class attribute, return type, or variable. |
|
|
| For example, to document a parameter `name` in a function `hi` you could do: |
|
|
| ```Python |
| from typing import Annotated |
|
|
| from annotated_doc import Doc |
|
|
| def hi(name: Annotated[str, Doc("Who to say hi to")]) -> None: |
| print(f"Hi, {name}!") |
| ``` |
|
|
| You can also use it to document class attributes: |
|
|
| ```Python |
| from typing import Annotated |
|
|
| from annotated_doc import Doc |
|
|
| class User: |
| name: Annotated[str, Doc("The user's name")] |
| age: Annotated[int, Doc("The user's age")] |
| ``` |
|
|
| The same way, you could document return types and variables, or anything that could have a type annotation with `Annotated`. |
|
|
| |
|
|
| `annotated-doc` was made for: |
|
|
| * [FastAPI](https://fastapi.tiangolo.com/) |
| * [Typer](https://typer.tiangolo.com/) |
| * [SQLModel](https://sqlmodel.tiangolo.com/) |
| * [Asyncer](https://asyncer.tiangolo.com/) |
|
|
| `annotated-doc` is supported by [griffe-typingdoc](https://github.com/mkdocstrings/griffe-typingdoc), which powers reference documentation like the one in the [FastAPI Reference](https://fastapi.tiangolo.com/reference/). |
|
|
| |
|
|
| You are already comfortable with one of the existing docstring formats, like: |
|
|
| * Sphinx |
| * numpydoc |
| * Google |
| * Keras |
|
|
| Your team is already comfortable using them. |
|
|
| You prefer having the documentation about parameters all together in a docstring, separated from the code defining them. |
|
|
| You care about a specific set of users, using one specific editor, and that editor already has support for the specific docstring format you use. |
|
|
| |
|
|
| * No micro-syntax to learn for newcomers, it’s **just Python** syntax. |
| * **Editing** would be already fully supported by default by any editor (current or future) supporting Python syntax, including syntax errors, syntax highlighting, etc. |
| * **Rendering** would be relatively straightforward to implement by static tools (tools that don't need runtime execution), as the information can be extracted from the AST they normally already create. |
| * **Deduplication of information**: the name of a parameter would be defined in a single place, not duplicated inside of a docstring. |
| * **Elimination** of the possibility of having **inconsistencies** when removing a parameter or class variable and **forgetting to remove** its documentation. |
| * **Minimization** of the probability of adding a new parameter or class variable and **forgetting to add its documentation**. |
| * **Elimination** of the possibility of having **inconsistencies** between the **name** of a parameter in the **signature** and the name in the docstring when it is renamed. |
| * **Access** to the documentation string for each symbol at **runtime**, including existing (older) Python versions. |
| * A more formalized way to document other symbols, like type aliases, that could use Annotated. |
| * **Support** for apps using FastAPI, Typer and others. |
| * **AI Accessibility**: AI tools will have an easier way understanding each parameter as the distance from documentation to parameter is much closer. |

| ## History |
| |
| I ([@tiangolo](https://github.com/tiangolo)) originally wanted for this to be part of the Python standard library (in [PEP 727](https://peps.python.org/pep-0727/)), but the proposal was withdrawn as there was a fair amount of negative feedback and opposition. |
| |
| The conclusion was that this was better done as an external effort, in a third-party library. |
| |
| So, here it is, with a simpler approach, as a third-party library, in a way that can be used by others, starting with FastAPI and friends. |
