python_version < "3.11" +Provides-Extra: tz +Requires-Dist: tzdata; extra == "tz" +Dynamic: license-file + +Alembic is a database migrations tool written by the author +of `SQLAlchemy `_. A migrations tool +offers the following functionality: + +* Can emit ALTER statements to a database in order to change + the structure of tables and other constructs +* Provides a system whereby "migration scripts" may be constructed; + each script indicates a particular series of steps that can "upgrade" a + target database to a new version, and optionally a series of steps that can + "downgrade" similarly, doing the same steps in reverse. +* Allows the scripts to execute in some sequential manner. + +The goals of Alembic are: + +* Very open ended and transparent configuration and operation. A new + Alembic environment is generated from a set of templates which is selected + among a set of options when setup first occurs. The templates then deposit a + series of scripts that define fully how database connectivity is established + and how migration scripts are invoked; the migration scripts themselves are + generated from a template within that series of scripts. The scripts can + then be further customized to define exactly how databases will be + interacted with and what structure new migration files should take. +* Full support for transactional DDL. The default scripts ensure that all + migrations occur within a transaction - for those databases which support + this (Postgresql, Microsoft SQL Server), migrations can be tested with no + need to manually undo changes upon failure. +* Minimalist script construction. Basic operations like renaming + tables/columns, adding/removing columns, changing column attributes can be + performed through one line commands like alter_column(), rename_table(), + add_constraint(). There is no need to recreate full SQLAlchemy Table + structures for simple operations like these - the functions themselves + generate minimalist schema structures behind the scenes to achieve the given + DDL sequence. +* "auto generation" of migrations. While real world migrations are far more + complex than what can be automatically determined, Alembic can still + eliminate the initial grunt work in generating new migration directives + from an altered schema. The ``--autogenerate`` feature will inspect the + current status of a database using SQLAlchemy's schema inspection + capabilities, compare it to the current state of the database model as + specified in Python, and generate a series of "candidate" migrations, + rendering them into a new migration script as Python directives. The + developer then edits the new file, adding additional directives and data + migrations as needed, to produce a finished migration. Table and column + level changes can be detected, with constraints and indexes to follow as + well. +* Full support for migrations generated as SQL scripts. Those of us who + work in corporate environments know that direct access to DDL commands on a + production database is a rare privilege, and DBAs want textual SQL scripts. + Alembic's usage model and commands are oriented towards being able to run a + series of migrations into a textual output file as easily as it runs them + directly to a database. Care must be taken in this mode to not invoke other + operations that rely upon in-memory SELECTs of rows - Alembic tries to + provide helper constructs like bulk_insert() to help with data-oriented + operations that are compatible with script-based DDL. +* Non-linear, dependency-graph versioning. Scripts are given UUID + identifiers similarly to a DVCS, and the linkage of one script to the next + is achieved via human-editable markers within the scripts themselves. + The structure of a set of migration files is considered as a + directed-acyclic graph, meaning any migration file can be dependent + on any other arbitrary set of migration files, or none at + all. Through this open-ended system, migration files can be organized + into branches, multiple roots, and mergepoints, without restriction. + Commands are provided to produce new branches, roots, and merges of + branches automatically. +* Provide a library of ALTER constructs that can be used by any SQLAlchemy + application. The DDL constructs build upon SQLAlchemy's own DDLElement base + and can be used standalone by any application or script. +* At long last, bring SQLite and its inability to ALTER things into the fold, + but in such a way that SQLite's very special workflow needs are accommodated + in an explicit way that makes the most of a bad situation, through the + concept of a "batch" migration, where multiple changes to a table can + be batched together to form a series of instructions for a single, subsequent + "move-and-copy" workflow. You can even use "move-and-copy" workflow for + other databases, if you want to recreate a table in the background + on a busy system. + +Documentation and status of Alembic is at

return types, and variables inline, with `Annotated`. + + + Test + + + Coverage + + + Package version + + + Supported Python versions + + +## Installation + +```bash +pip install annotated-doc +``` + +Or with `uv`: + +```Python +uv add annotated-doc +``` + +## Usage + +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`. + +## Who Uses This + +`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/). + +## Reasons not to use `annotated-doc` + +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. + +## Reasons to use `annotated-doc` + +* 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. + +## License + +This project is licensed under the terms of the MIT license. diff --git

In some cases, +we also note alternative representations which do not require this package. + +## Install + +```bash +pip install annotated-types +``` + +## Examples + +```python +from typing import Annotated +from annotated_types import Gt, Len, Predicate + +class MyClass: + age: Annotated[int, Gt(18)] # Valid: 19, 20, ... + # Invalid: 17, 18, "19", 19.0, ... + factors: list[Annotated[int, Predicate(is_prime)]] # Valid: 2, 3, 5, 7, 11, ... + # Invalid: 4, 8, -2, 5.0, "prime", ... + + my_list: Annotated[list[int], Len(0, 10)] # Valid: [], [10, 20, 30, 40, 50] + # Invalid: (1, 2), ["abc"], [0] * 20 +``` + +## Documentation + +_While `annotated-types` avoids runtime checks for performance, users should not +construct invalid combinations such as `MultipleOf("non-numeric")` or `Annotated[int, Len(3)]`. +Downstream implementors may choose to raise an error, emit a warning, silently ignore +a metadata item, etc., if the metadata objects described below are used with an +incompatible type - or for any other reason!_ + +### Gt, Ge, Lt, Le + +Express inclusive and/or exclusive bounds on orderable values - which may be numbers, +dates, times, strings, sets, etc. Note that the boundary value need not be of the +same type that was annotated, so long as they can be compared: `Annotated[int, Gt(1.5)]` +is fine, for example, and implies that the value is an integer x such that `x > 1.5`. + +We suggest that implementors may also interpret `functools.partial(operator.le, 1.5)` +as being equivalent to `Gt(1.5)`, for users who wish to avoid a runtime dependency on +the `annotated-types` package. + +To be explicit, these types have the following meanings: + +* `Gt(x)` - value must be "Greater Than" `x` - equivalent to exclusive minimum +* `Ge(x)` - value must be "Greater than or Equal" to `x` - equivalent to inclusive minimum +* `Lt(x)` - value must be "Less Than" `x` - equivalent to exclusive maximum +* `Le(x)` - value must be "Less than or Equal" to `x` - equivalent to inclusive maximum + +### Interval + +`Interval(gt, ge, lt, le)` allows you to specify an upper and lower bound with a single +metadata object. `None` attributes should be ignored, and non-`None` attributes +treated as per the single bounds above. + +### MultipleOf + +`MultipleOf(multiple_of=x)` might be interpreted in two ways: + +1. Python semantics, implying `value % multiple_of == 0`, or +2. [JSONschema semantics](https://json-schema.org/draft/2020-12/json-schema-validation.html#rfc.section.6.2.1), + where `int(value / multiple_of) == value / multiple_of`. + +We encourage users to be aware of these two common interpretations and their +distinct behaviours, especially since very large or non-integer numbers make +it easy to cause silent data corruption due to floating-point imprecision. + +We encourage libraries to carefully document which interpretation they implement. + +### MinLen, MaxLen, Len + +`Len()` implies that `min_length <= len(value) <= max_length` - lower and upper bounds are inclusive. + +As well as `Len()` which can optionally include upper and lower bounds, we also +provide `MinLen(x)` and `MaxLen(y)` which are equivalent to `Len(min_length=x)` +and `Len(max_length=y)` respectively. + +`Len`, `MinLen`, and `MaxLen` may be used with any type which supports `len(value)`. + +Examples of usage: + +* `Annotated[list, MaxLen(10)]` (or `Annotated[list, Len(max_length=10))`) - list must have a length of 10 or less +* `Annotated[str, MaxLen(10)]` - string must have a length of 10 or less +* `Annotated[list, MinLen(3))` (or `Annotated[list, Len(min_length=3))`) - list must have a length of 3 or more +* `Annotated[list, Len(4, 6)]` - list must have a length of 4, 5, or 6 +* `Annotated[list, Len(8, 8)]` - list must have a length of exactly 8 + +#### Changed in v0.4.0 + +* `min_inclusive` has been renamed to `min_length`, no change in meaning +* `max_exclusive` has been renamed to `max_length`, upper bound is now **inclusive** instead of **exclusive** +* The recommendation that slices are interpreted as `Len` has been removed due to ambiguity and different semantic + meaning of the upper bound in slices vs. `Len` + +See [issue #23](https://github.com/annotated-types/annotated-types/issues/23) for discussion. + +### Timezone + +`Timezone` can be used with a `datetime` or a `time` to express which timezones +are allowed. `Annotated[datetime, Timezone(None)]` must be a naive datetime. +`Timezone[...]` ([literal ellipsis](https://docs.python.org/3/library/constants.html#Ellipsis)) +expresses that any timezone-aware datetime is allowed. You may also pass a specific +timezone string or [`tzinfo`](https://docs.python.org/3/library/datetime.html#tzinfo-objects) +object such as `Timezone(timezone.utc)` or `Timezone("Africa/Abidjan")` to express that you only +allow a specific timezone, though we note that this is often a symptom of fragile design. + +#### Changed in v0.x.x + +* `Timezone` accepts [`tzinfo`](https://docs.python.org/3/library/datetime.html#tzinfo-objects) objects instead of + `timezone`, extending compatibility to [`zoneinfo`](https://docs.python.org/3/library/zoneinfo.html) and third party libraries. + +### Unit + +`Unit(unit: str)` expresses that the annotated numeric value is the magnitude of +a quantity with the specified unit. For example, `Annotated[float, Unit("m/s")]` +would be a float representing a velocity in meters per second. + +Please note that `annotated_types` itself makes no attempt to parse or validate +the unit string in any way. That is left entirely to downstream libraries, +such as [`pint`](https://pint.readthedocs.io) or +[`astropy.units`](https://docs.astropy.org/en/stable/units/). + +An example of how a library might use this metadata: + +```python +from annotated_types import Unit +from typing import Annotated, TypeVar, Callable, Any, get_origin, get_args + +# given a type annotated with a unit: +Meters = Annotated[float, Unit("m")] + + +# you can cast the annotation to a specific unit type with any +# callable that accepts a string and returns the desired type +T = TypeVar("T") +def cast_unit(tp: Any, unit_cls: Callable[[str], T]) -> T | None: + if get_origin(tp) is Annotated: + for arg in get_args(tp): + if isinstance(arg, Unit): + return unit_cls(arg.unit) + return None + + +# using `pint` +import pint +pint_unit = cast_unit(Meters, pint.Unit) + + +# using `astropy.units` +import astropy.units as u +astropy_unit = cast_unit(Meters, u.Unit) +``` + +### Predicate + +`Predicate(func: Callable)` expresses that `func(value)` is truthy for valid values. +Users should prefer the statically inspectable metadata above, but if you need +the full power and flexibility of arbitrary runtime predicates... here it is. + +For some common constraints, we provide generic types: + +* `IsLower = Annotated[T, Predicate(str.islower)]` +* `IsUpper = Annotated[T, Predicate(str.isupper)]` +* `IsDigit = Annotated[T, Predicate(str.isdigit)]` +* `IsFinite = Annotated[T, Predicate(math.isfinite)]` +* `IsNotFinite = Annotated[T, Predicate(Not(math.isfinite))]` +* `IsNan = Annotated[T, Predicate(math.isnan)]` +* `IsNotNan = Annotated[T, Predicate(Not(math.isnan))]` +* `IsInfinite = Annotated[T, Predicate(math.isinf)]` +* `IsNotInfinite = Annotated[T, Predicate(Not(math.isinf))]` + +so that you can write e.g. `x: IsFinite[float] = 2.0` instead of the longer +(but exactly equivalent) `x: Annotated[float, Predicate(math.isfinite)] = 2.0`. + +Some libraries might have special logic to handle known or understandable predicates, +for example by checking for `str.isdigit` and using its presence to both call custom +logic to enforce digit-only strings, and customise some generated external schema. +Users are therefore encouraged to avoid indirection like `lambda s: s.lower()`, in +favor of introspectable methods such as `str.lower` or `re.compile("pattern").search`. + +To enable basic negation of commonly used predicates like `math.isnan` without introducing introspection that makes it impossible for implementers to introspect the predicate we provide a `Not` wrapper that simply negates the predicate in an introspectable manner. Several of the predicates listed above are created in this manner. + +We do not specify what behaviour should be expected for predicates that raise +an exception. For example `Annotated[int, Predicate(str.isdigit)]` might silently +skip invalid constraints, or statically raise an error; or it might try calling it +and then propagate or discard the resulting +`TypeError: descriptor 'isdigit' for 'str' objects doesn't apply to a 'int' object` +exception. We encourage libraries to document the behaviour they choose. + +### Doc + +`doc()` can be used to add documentation information in `Annotated`, for function and method parameters, variables, class attributes, return types, and any place where `Annotated` can be used. + +It expects a value that can be statically analyzed, as the main use case is for static analysis, editors, documentation generators, and similar tools. + +It returns a `DocInfo` class with a single attribute `documentation` containing the value passed to `doc()`. + +This is the early adopter's alternative form of the [`typing-doc` proposal](https://github.com/tiangolo/fastapi/blob/typing-doc/typing_doc.md). + +### Integrating downstream types with `GroupedMetadata` + +Implementers may choose to provide a convenience wrapper that groups multiple pieces of metadata. +This can help reduce verbosity and cognitive overhead for users. +For example, an implementer like Pydantic might provide a `Field` or `Meta` type that accepts keyword arguments and transforms these into low-level metadata: + +```python +from dataclasses import dataclass +from typing import Iterator +from annotated_types import GroupedMetadata, Ge + +@dataclass +class Field(GroupedMetadata): + ge: int | None = None + description: str | None = None + + def __iter__(self) -> Iterator[object]: + # Iterating over a GroupedMetadata object should yield annotated-types + # constraint metadata objects which describe it as fully as possible, + # and may include other unknown objects too. + if self.ge is not None: + yield Ge(self.ge) + if self.description is not None: + yield Description(self.description) +``` + +Libraries consuming annotated-types constraints should check for `GroupedMetadata` and unpack it by iterating over the object and treating the results as if they had been "unpacked" in the `Annotated` type. The same logic should be applied to the [PEP 646 `Unpack` type](https://peps.python.org/pep-0646/), so that `Annotated[T, Field(...)]`, `Annotated[T, Unpack[Field(...)]]` and `Annotated[T, *Field(...)]` are all treated consistently. + +Libraries consuming annotated-types should also ignore any metadata they do not recongize that came from unpacking a `GroupedMetadata`, just like they ignore unrecognized metadata in `Annotated` itself. + +Our own `annotated_types.Interval` class is a `GroupedMetadata` which unpacks itself into `Gt`, `Lt`, etc., so this is not an abstract concern. Similarly, `annotated_types.Len` is a `GroupedMetadata` which unpacks itself into `MinLen` (optionally) and `MaxLen`. + +### Consuming metadata + +We intend to not be prescriptive as to _how_ the metadata and constraints are used, but as an example of how one might parse constraints from types annotations see our [implementation in `test_main.py`](https://github.com/annotated-types/annotated-types/blob/f59cf6d1b5255a0fe359b93896759a180bec30ae/tests/test_main.py#L94-L103). + +It is up to the implementer to determine how this metadata is used. +You could use the metadata for runtime type checking, for generating schemas or to generate example data, amongst other use cases. + +## Design & History + +This package was designed at the PyCon 2022 sprints by the maintainers of Pydantic +and Hypothesis, with the goal of making it as easy as possible for end-users to +provide more informative annotations for use by runtime libraries. + +It is deliberately minimal, and following PEP-593 allows considerable downstream +discretion in what (if anything!) they choose to support. Nonetheless, we expect +that staying simple and covering _only_ the most common use-cases will give users +and maintainers the best experience we can.

It implements Trio-like `structured concurrency`_ (SC) on top of asyncio and works in harmony +with the native SC of Trio itself. + +Applications and libraries written against AnyIO's API will run unmodified on either asyncio_ or +Trio_. AnyIO can also be adopted into a library or application incrementally – bit by bit, no full +refactoring necessary. It will blend in with the native libraries of your chosen backend. + +To find out why you might want to use AnyIO's APIs instead of asyncio's, you can read about it +`here `_. + +Documentation +------------- + +View full documentation at: https://anyio.readthedocs.io/ + +Features +-------- + +AnyIO offers the following functionality: + +* Task groups (nurseries_ in trio terminology) +* High-level networking (TCP, UDP and UNIX sockets) + + * `Happy eyeballs`_ algorithm for TCP connections (more robust than that of asyncio on Python + 3.8) + * async/await style UDP sockets (unlike asyncio where you still have to use Transports and + Protocols) + +* A versatile API for byte streams and object streams +* Inter-task synchronization and communication (locks, conditions, events, semaphores, object + streams) +* Worker threads +* Subprocesses +* Subinterpreter support for code parallelization (on Python 3.13 and later) +* Asynchronous file I/O (using worker threads) +* Signal handling +* Asynchronous version of the functools_ module + +AnyIO also comes with its own pytest_ plugin which also supports asynchronous fixtures. +It even works with the popular Hypothesis_ library. + +.. _asyncio: https://docs.python.org/3/library/asyncio.html +.. _Trio: https://github.com/python-trio/trio +.. _structured concurrency: https://en.wikipedia.org/wiki/Structured_concurrency

Also! I never back down on a good challenge! + +I **don't care** about the **originating charset** encoding, because **two different tables** can +produce **two identical rendered string.** +What I want is to get readable text, the best I can. + +In a way, **I'm brute forcing text decoding.** How cool is that ? 😎 + +Don't confuse package **ftfy** with charset-normalizer or chardet. ftfy goal is to repair Unicode string whereas charset-normalizer to convert raw file in unknown encoding to unicode. + +## 🍰 How + + - Discard all charset encoding table that could not fit the binary content. + - Measure noise, or the mess once opened (by chunks) with a corresponding charset encoding. + - Extract matches with the lowest mess detected. + - Additionally, we measure coherence / probe for a language. + +**Wait a minute**, what is noise/mess and coherence according to **YOU ?** + +*Noise :* I opened hundred of text files, **written by humans**, with the wrong encoding table. **I observed**, then +**I established** some ground rules about **what is obvious** when **it seems like** a mess (aka. defining noise in rendered text). + I know that my interpretation of what is noise is probably incomplete, feel free to contribute in order to + improve or rewrite it. + +*Coherence :* For each language there is on earth, we have computed ranked letter appearance occurrences (the best we can). So I thought +that intel is worth something here. So I use those records against decoded text to check if I can detect intelligent design. + +## ⚡ Known limitations + + - Language detection is unreliable when text contains two or more languages sharing identical letters. (eg. HTML (english tags) + Turkish content (Sharing Latin characters)) + - Every charset detector heavily depends on sufficient content. In common cases, do not bother run detection on very tiny content. + +## ⚠️ About Python EOLs + +**If you are running:** + +- Python >=2.7,<3.5: Unsupported +- Python 3.5: charset-normalizer < 2.1 +- Python 3.6: charset-normalizer < 3.1 +- Python 3.7: charset-normalizer < 4.0 + +Upgrade your Python interpreter as soon as possible. + +## 👤 Contributing + +Contributions, issues and feature requests are very much welcome.

+

+ FastAPI framework, high performance, easy to learn, fast to code, ready for production +

+

+ + Test + + + Coverage + + + Package version + + + Supported Python versions + +

+ +--- + +**Documentation**: https://fastapi.tiangolo.com + +**Source Code**: https://github.com/fastapi/fastapi + +--- + +FastAPI is a modern, fast (high-performance), web framework for building APIs with Python based on standard Python type hints. + +The key features are: + +* **Fast**: Very high performance, on par with **NodeJS** and **Go** (thanks to Starlette and Pydantic). [One of the fastest Python frameworks available](#performance). +* **Fast to code**: Increase the speed to develop features by about 200% to 300%. * +* **Fewer bugs**: Reduce about 40% of human (developer) induced errors. * +* **Intuitive**: Great editor support. Completion everywhere. Less time debugging. +* **Easy**: Designed to be easy to use and learn. Less time reading docs. +* **Short**: Minimize code duplication. Multiple features from each parameter declaration. Fewer bugs. +* **Robust**: Get production-ready code. With automatic interactive documentation. +* **Standards-based**: Based on (and fully compatible with) the open standards for APIs: OpenAPI (previously known as Swagger) and JSON Schema. + +* estimation based on tests conducted by an internal development team, building production applications. + +## Sponsors + + +### Keystone Sponsor + + + +### Gold and Silver Sponsors + + + + + + + + + + + + + + + + + + + + + + +Other sponsors + +## Opinions + +"_[...] I'm using **FastAPI** a ton these days. [...] I'm actually planning to use it for all of my team's **ML services at Microsoft**. Some of them are getting integrated into the core **Windows** product and some **Office** products._" + +

+ +--- + +## FastAPI mini documentary + +There's a FastAPI mini documentary released at the end of 2025, you can watch it online: + +FastAPI Mini Documentary + +## **Typer**, the FastAPI of CLIs + + + +If you are building a CLI app to be used in the terminal instead of a web API, check out **Typer**. + +**Typer** is FastAPI's little sibling. And it's intended to be the **FastAPI of CLIs**. ⌨️ 🚀 + +## Requirements + +FastAPI stands on the shoulders of giants: + +* Starlette for the web parts. +* Pydantic for the data parts. + +## Installation + +Create and activate a virtual environment and then install FastAPI: + +
+ +```console +$ pip install "fastapi[standard]" + +---> 100% +``` + +
+ +**Note**: Make sure you put `"fastapi[standard]"` in quotes to ensure it works in all terminals. + +## Example + +### Create it + +Create a file `main.py` with: + +```Python +from fastapi import FastAPI + +app = FastAPI() + + +@app.get("/") +def read_root(): + return {"Hello": "World"} + + +@app.get("/items/{item_id}") +def read_item(item_id: int, q: str | None = None): + return {"item_id": item_id, "q": q} +``` + +
+Or use async def... + +If your code uses `async` / `await`, use `async def`: + +```Python hl_lines="7 12" +from fastapi import FastAPI + +app = FastAPI() + + +@app.get("/") +async def read_root(): + return {"Hello": "World"} + + +@app.get("/items/{item_id}") +async def read_item(item_id: int, q: str | None = None): + return {"item_id": item_id, "q": q} +``` + +**Note**: + +If you don't know, check the _"In a hurry?"_ section about `async` and `await` in the docs. + +
+ +### Run it + +Run the server with: + +
+ +```console +$ fastapi dev main.py + + ╭────────── FastAPI CLI - Development mode ───────────╮ + │ │ + │ Serving at: http://127.0.0.1:8000 │ + │ │ + │ API docs: http://127.0.0.1:8000/docs │ + │ │ + │ Running in development mode, for production use: │ + │ │ + │ fastapi run │ + │ │ + ╰─────────────────────────────────────────────────────╯ + +INFO: Will watch for changes in these directories: ['/home/user/code/awesomeapp'] +INFO: Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit) +INFO: Started reloader process [2248755] using WatchFiles +INFO: Started server process [2248757] +INFO: Waiting for application startup. +INFO: Application startup complete. +``` + +
+ +
+About the command fastapi dev main.py... + +The command `fastapi dev` reads your `main.py` file, detects the **FastAPI** app in it, and starts a server using Uvicorn. + +By default, `fastapi dev` will start with auto-reload enabled for local development. + +You can read more about it in the FastAPI CLI docs. + +
+ +### Check it + +Open your browser at http://127.0.0.1:8000/items/5?q=somequery. + +You will see the JSON response as: + +```JSON +{"item_id": 5, "q": "somequery"} +``` + +You already created an API that: + +* Receives HTTP requests in the _paths_ `/` and `/items/{item_id}`. +* Both _paths_ take `GET` operations (also known as HTTP _methods_). +* The _path_ `/items/{item_id}` has a _path parameter_ `item_id` that should be an `int`. +* The _path_ `/items/{item_id}` has an optional `str` _query parameter_ `q`. + +### Interactive API docs + +Now go to http://127.0.0.1:8000/docs. + +You will see the automatic interactive API documentation (provided by Swagger UI): + +![Swagger UI](https://fastapi.tiangolo.com/img/index/index-01-swagger-ui-simple.png) + +### Alternative API docs + +And now, go to http://127.0.0.1:8000/redoc. + +You will see the alternative automatic documentation (provided by ReDoc): + +![ReDoc](https://fastapi.tiangolo.com/img/index/index-02-redoc-simple.png) + +## Example upgrade + +Now modify the file `main.py` to receive a body from a `PUT` request. + +Declare the body using standard Python types, thanks to Pydantic. + +```Python hl_lines="2 7-10 23-25" +from fastapi import FastAPI +from pydantic import BaseModel + +app = FastAPI() + + +class Item(BaseModel): + name: str + price: float + is_offer: bool | None = None + + +@app.get("/") +def read_root(): + return {"Hello": "World"} + + +@app.get("/items/{item_id}") +def read_item(item_id: int, q: str | None = None): + return {"item_id": item_id, "q": q} + + +@app.put("/items/{item_id}") +def update_item(item_id: int, item: Item): + return {"item_name": item.name, "item_id": item_id} +``` + +The `fastapi dev` server should reload automatically. + +### Interactive API docs upgrade + +Now go to http://127.0.0.1:8000/docs. + +* The interactive API documentation will be automatically updated, including the new body: + +![Swagger UI](https://fastapi.tiangolo.com/img/index/index-03-swagger-02.png) + +* Click on the button "Try it out", it allows you to fill the parameters and directly interact with the API: + +![Swagger UI interaction](https://fastapi.tiangolo.com/img/index/index-04-swagger-03.png) + +* Then click on the "Execute" button, the user interface will communicate with your API, send the parameters, get the results and show them on the screen: + +![Swagger UI interaction](https://fastapi.tiangolo.com/img/index/index-05-swagger-04.png) + +### Alternative API docs upgrade + +And now, go to http://127.0.0.1:8000/redoc. + +* The alternative documentation will also reflect the new query parameter and body: + +![ReDoc](https://fastapi.tiangolo.com/img/index/index-06-redoc-02.png) + +### Recap + +In summary, you declare **once** the types of parameters, body, etc. as function parameters. + +You do that with standard modern Python types. + +You don't have to learn a new syntax, the methods or classes of a specific library, etc. + +Just standard **Python**. + +For example, for an `int`: + +```Python +item_id: int +``` + +or for a more complex `Item` model: + +```Python +item: Item +``` + +...and with that single declaration you get: + +* Editor support, including: + * Completion. + * Type checks. +* Validation of data: + * Automatic and clear errors when the data is invalid. + * Validation even for deeply nested JSON objects. +* Conversion of input data: coming from the network to Python data and types. Reading from: + * JSON. + * Path parameters. + * Query parameters. + * Cookies. + * Headers. + * Forms. + * Files. +* Conversion of output data: converting from Python data and types to network data (as JSON): + * Convert Python types (`str`, `int`, `float`, `bool`, `list`, etc). + * `datetime` objects. + * `UUID` objects. + * Database models. + * ...and many more. +* Automatic interactive API documentation, including 2 alternative user interfaces: + * Swagger UI. + * ReDoc. + +--- + +Coming back to the previous code example, **FastAPI** will: + +* Validate that there is an `item_id` in the path for `GET` and `PUT` requests. +* Validate that the `item_id` is of type `int` for `GET` and `PUT` requests. + * If it is not, the client will see a useful, clear error. +* Check if there is an optional query parameter named `q` (as in `http://127.0.0.1:8000/items/foo?q=somequery`) for `GET` requests. + * As the `q` parameter is declared with `= None`, it is optional. + * Without the `None` it would be required (as is the body in the case with `PUT`). +* For `PUT` requests to `/items/{item_id}`, read the body as JSON: + * Check that it has a required attribute `name` that should be a `str`. + * Check that it has a required attribute `price` that has to be a `float`. + * Check that it has an optional attribute `is_offer`, that should be a `bool`, if present. + * All this would also work for deeply nested JSON objects. +* Convert from and to JSON automatically. +* Document everything with OpenAPI, that can be used by: + * Interactive documentation systems. + * Automatic client code generation systems, for many languages. +* Provide 2 interactive documentation web interfaces directly. + +--- + +We just scratched the surface, but you already get the idea of how it all works. + +Try changing the line with: + +```Python + return {"item_name": item.name, "item_id": item_id} +``` + +...from: + +```Python + ... "item_name": item.name ... +``` + +...to: + +```Python + ... "item_price": item.price ... +``` + +...and see how your editor will auto-complete the attributes and know their types: + +![editor support](https://fastapi.tiangolo.com/img/vscode-completion.png) + +For a more complete example including more features, see the Tutorial - User Guide. + +**Spoiler alert**: the tutorial - user guide includes: + +* Declaration of **parameters** from other different places as: **headers**, **cookies**, **form fields** and **files**. +* How to set **validation constraints** as `maximum_length` or `regex`. +* A very powerful and easy to use **Dependency Injection** system. +* Security and authentication, including support for **OAuth2** with **JWT tokens** and **HTTP Basic** auth. +* More advanced (but equally easy) techniques for declaring **deeply nested JSON models** (thanks to Pydantic). +* **GraphQL** integration with Strawberry and other libraries. +* Many extra features (thanks to Starlette) as: + * **WebSockets** + * extremely easy tests based on HTTPX and `pytest` + * **CORS** + * **Cookie Sessions** + * ...and more. + +### Deploy your app (optional) + +You can optionally deploy your FastAPI app to FastAPI Cloud, go and join the waiting list if you haven't. 🚀 + +If you already have a **FastAPI Cloud** account (we invited you from the waiting list 😉), you can deploy your application with one command. + +Before deploying, make sure you are logged in: + +
+ +```console +$ fastapi login + +You are logged in to FastAPI Cloud 🚀 +``` + +
+ +Then deploy your app: + +
+ +```console +$ fastapi deploy + +Deploying to FastAPI Cloud... + +✅ Deployment successful! + +🐔 Ready the chicken! Your app is ready at https://myapp.fastapicloud.dev +``` + +
+ +That's it! Now you can access your app at that URL. ✨ + +#### About FastAPI Cloud + +**FastAPI Cloud** is built by the same author and team behind **FastAPI**. + +It streamlines the process of **building**, **deploying**, and **accessing** an API with minimal effort. + +It brings the same **developer experience** of building apps with FastAPI to **deploying** them to the cloud. 🎉 + +FastAPI Cloud is the primary sponsor and funding provider for the *FastAPI and friends* open source projects. ✨ + +#### Deploy to other cloud providers + +FastAPI is open source and based on standards. You can deploy FastAPI apps to any cloud provider you choose. + +Follow your cloud provider's guides to deploy FastAPI apps with them. 🤓 + +## Performance + +Independent TechEmpower benchmarks show **FastAPI** applications running under Uvicorn as one of the fastest Python frameworks available, only below Starlette and Uvicorn themselves (used internally by FastAPI). (*) + +To understand more about it, see the section Benchmarks. + +## Dependencies + +FastAPI depends on Pydantic and Starlette. + +### `standard` Dependencies + +When you install FastAPI with `pip install "fastapi[standard]"` it comes with the `standard` group of optional dependencies: + +Used by Pydantic: + +* email-validator - for email validation. + +Used by Starlette: + +* httpx - Required if you want to use the `TestClient`. +* jinja2 - Required if you want to use the default template configuration. +* python-multipart - Required if you want to support form "parsing", with `request.form()`. + +Used by FastAPI: + +* uvicorn - for the server that loads and serves your application. This includes `uvicorn[standard]`, which includes some dependencies (e.g. `uvloop`) needed for high performance serving. +* `fastapi-cli[standard]` - to provide the `fastapi` command. + * This includes `fastapi-cloud-cli`, which allows you to deploy your FastAPI application to FastAPI Cloud. + +### Without `standard` Dependencies + +If you don't want to include the `standard` optional dependencies, you can install with `pip install fastapi` instead of `pip install "fastapi[standard]"`. + +### Without `fastapi-cloud-cli` + +If you want to install FastAPI with the standard dependencies but without the `fastapi-cloud-cli`, you can install with `pip install "fastapi[standard-no-fastapi-cloud-cli]"`. + +### Additional Optional Dependencies + +There are some additional dependencies you might want to install. + +Additional optional Pydantic dependencies: + +* pydantic-settings - for settings management. +* pydantic-extra-types - for extra types to be used with Pydantic. + +Additional optional FastAPI dependencies: + +* orjson - Required if you want to use `ORJSONResponse`. +* ujson - Required if you want to use `UJSONResponse`. + +## License + +This project

This file is included into docs/history.rst + + +Greenlets are lightweight coroutines for in-process concurrent +programming. + +The "greenlet" package is a spin-off of `Stackless`_, a version of +CPython that supports micro-threads called "tasklets". Tasklets run +pseudo-concurrently (typically in a single or a few OS-level threads) +and are synchronized with data exchanges on "channels". + +A "greenlet", on the other hand, is a still more primitive notion of +micro-thread with no implicit scheduling; coroutines, in other words. +This is useful when you want to control exactly when your code runs. +You can build custom scheduled micro-threads on top of greenlet; +however, it seems that greenlets are useful on their own as a way to +make advanced control flow structures. For example, we can recreate +generators; the difference with Python's own generators is that our +generators can call nested functions and the nested functions can +yield values too. (Additionally, you don't need a "yield" keyword. See +the example in `test_generator.py +`_). + +Greenlets are provided as a C extension module for the regular unmodified +interpreter. + +.. _`Stackless`: http://www.stackless.com + + +Who is using

However, once the greenlet is actually switched to + for the first time, ``g_initialstub`` (which doesn't actually + "return" while the greenlet is running) stores a new _PyCFrame on + its local stack, and copies the appropriate values from the + currently running _PyCFrame; this is then made the _PyCFrame for the + newly-minted greenlet. ``g_initialstub`` then proceeds to call + ``glet.run()``, which results in ``PyEval_...`` adding the + _PyCFrame to the list. Switches continue as normal. Finally, when + the greenlet finishes, the call to ``glet.run()`` returns and + the _PyCFrame is taken out of the linked list and the stack value + is now unused and free to expire. + + XXX: I think we can do better. If we're deallocing in the same + thread, can't we traverse the list and unlink our frame? + Can we just keep a reference to the thread state in case we + dealloc in another thread?

MSVC on 32-bit windows is an exception. There, C++ + * exceptions are dealt with using Windows' Structured Exception Handling + * (SEH). + * + * SEH is implemented as a singly linked list of nodes. The + * head of this list is stored in the Thread Information Block, which itself + * is pointed to from the FS register. It's the first field in the structure, + * or offset 0, so we can access it using assembly FS:[0], or the compiler + * intrinsics and field offset information from the headers (as we do below). + * Somewhat unusually, the tail of the list doesn't have prev == NULL, it has + * prev == 0xFFFFFFFF. + * + * SEH was designed for C, and traditionally uses the MSVC compiler + * intrinsincs __try{}/__except{}. It is also utilized for C++ exceptions by + * MSVC; there, every throw of a C++ exception raises a SEH error with the + * ExceptionCode 0xE06D7363; the SEH handler list is then traversed to + * deal with the exception. + * + * If the SEH list is corrupt, then when a C++ exception is thrown the program + * will abruptly exit with exit code 1. This does not use std::terminate(), so + * std::set_terminate() is useless to debug this. + * + * The SEH list is closely tied to the call stack; entering a function that + * uses __try{} or most C++ functions will push a new handler onto the front + * of the list. Returning from the function will remove the handler. Saving + * and restoring the head node of the SEH list (FS:[0]) per-greenlet is NOT + * ENOUGH to make SEH or exceptions work. + * + * Stack switching breaks SEH because the call stack no longer necessarily + * matches the SEH list. For example, given greenlet A that switches to + * greenlet B, at the moment of entering greenlet B, we will have any SEH + * handlers from greenlet A on the SEH list; greenlet B can then add its own + * handlers to the SEH list. When greenlet B switches back to greenlet A, + * greenlet B's handlers would still be on the SEH stack, but when switch() + * returns control to greenlet A, we have replaced the contents of the stack + * in memory, so all the address that greenlet B added to the SEH list are now + * invalid: part of the call stack has been unwound, but the SEH list was out + * of sync with the call stack. The net effect is that exception handling + * stops working. + * + * Thus, when switching greenlets, we need to be sure that the SEH list + * matches the effective call stack, "cutting out" any handlers that were + * pushed by the greenlet that switched out and which are no longer valid. + * + * The easiest way to do this is to capture the SEH list at the time the main + * greenlet for a thread is created, and, when initially starting a greenlet, + * start a new SEH list for it, which contains nothing but the handler + * established for the new greenlet itself, with the tail being the handlers + * for the main greenlet. If we then save and restore the SEH per-greenlet, + * they won't interfere with each others SEH lists. (No greenlet can unwind + * the call stack past the handlers established by the main greenlet). + * + * By observation, a new thread starts with three SEH handlers on the list. By + * the time we get around to creating the main greenlet, though, there can be + * many more, established by transient calls that lead to the creation of the + * main greenlet.

This means you can hook h11 up to your favorite network +API, and that could be anything you want: synchronous, threaded, +asynchronous, or your own implementation of `RFC 6214 +`_ -- h11 won't judge you. +(Compare this to the current state of the art, where every time a `new +network API `_ comes along then someone +gets to start over reimplementing the entire HTTP protocol from +scratch.) Cory Benfield made an `excellent blog post describing the +benefits of this approach +`_, or if you like video +then here's his `PyCon 2016 talk on the same theme +`_. + +This also means that h11 is not immediately useful out of the box: +it's a toolkit for building programs that speak HTTP, not something +that could directly replace ``requests`` or ``twisted.web`` or +whatever. But h11 makes it much easier to implement something like +``requests`` or ``twisted.web``. + +At a high level, working with h11 goes like this: + +1) First, create an ``h11.Connection`` object to track the state of a + single HTTP/1.1 connection. + +2) When you read data off the network, pass it to + ``conn.receive_data(...)``; you'll get back a list of objects + representing high-level HTTP "events". + +3) When you want to send a high-level HTTP event, create the + corresponding "event" object and pass it to ``conn.send(...)``; + this will give you back some bytes that you can then push out + through the network. + +For example, a client might instantiate and then send a +``h11.Request`` object, then zero or more ``h11.Data`` objects for the +request body (e.g., if this is a POST), and then a +``h11.EndOfMessage`` to indicate the end of the message. Then the +server would then send back a ``h11.Response``, some ``h11.Data``, and +its own ``h11.EndOfMessage``. If either side violates the protocol, +you'll get a ``h11.ProtocolError`` exception. + +h11 is suitable for implementing both servers and clients, and has a +pleasantly symmetric API: the events you send as a client are exactly +the ones that you receive as a server and vice-versa. + +`Here's an example of a tiny HTTP client +`_ + +It also has `a fine manual `_. + +FAQ +--- + +*Whyyyyy?* + +I wanted to play with HTTP in `Curio +`__ and `Trio +`__, which at the time didn't have any +HTTP libraries. So I thought, no big deal, Python has, like, a dozen +different implementations of HTTP, surely I can find one that's +reusable. I didn't find one, but I did find Cory's call-to-arms +blog-post. So I figured, well, fine, if I have to implement HTTP from +scratch, at least I can make sure no-one *else* has to ever again. + +*Should I use it?* + +Maybe. You should be aware that it's a very young project. But, it's +feature complete and has an exhaustive test-suite and complete docs, +so the next step is for people to try using it and see how it goes +:-). If you do then please let us know -- if nothing else we'll want +to talk to you before making any incompatible changes! + +*What are the features/limitations?* + +Roughly speaking, it's trying to be a robust, complete, and non-hacky +implementation of the first "chapter" of the HTTP/1.1 spec: `RFC 7230: +HTTP/1.1 Message Syntax and Routing +`_. That is, it mostly focuses on +implementing HTTP at the level of taking bytes on and off the wire, +and the headers related to that, and tries to be anal about spec +conformance. It doesn't know about higher-level concerns like URL +routing, conditional GETs, cross-origin cookie policies, or content +negotiation. But it does know how to take care of framing, +cross-version differences in keep-alive handling, and the "obsolete +line folding" rule, so you can focus your energies on the hard / +interesting parts for your application, and it tries to support the +full specification in the sense that any useful HTTP/1.1 conformant +application should be able to use h11. + +It's pure Python, and has no dependencies outside of the standard +library. + +It has a test suite with 100.0% coverage for both statements and +branches. + +Currently it supports Python 3 (testing on 3.8-3.12) and PyPy 3. +The last Python 2-compatible version was h11 0.11.x. +(Originally it had a Cython wrapper for `http-parser +`_ and a beautiful nested state +machine implemented with ``yield from`` to postprocess the output. But +I had to take these out -- the new *parser* needs fewer lines-of-code +than the old *parser wrapper*, is written in pure Python, uses no +exotic language syntax, and has more features. It's sad, really; that +old state machine was really slick. I just need a few sentences here +to mourn that.) + +I don't know how fast it is. I haven't benchmarked or profiled it yet, +so it's probably got a few pointless hot spots, and I've been trying +to err on the side of simplicity and robustness instead of +micro-optimization. But at the architectural level I tried hard to +avoid fundamentally bad decisions, e.g., I believe that all the +parsing algorithms remain linear-time even in the face of pathological +input like slowloris, and there are no byte-by-byte loops. (I also +believe that it maintains bounded memory usage in the face of +arbitrary/pathological input.) + +The whole library is ~800 lines-of-code. You can read and understand +the whole thing in less than an hour. Most of the energy invested in +this so far has been spent on trying to keep things simple by +minimizing special-cases and ad hoc state manipulation; even though it +is now quite small and simple, I'm still annoyed that I haven't +figured out how to make it even smaller and simpler. (Unfortunately, +HTTP does not lend itself to simplicity.) + +The API is ~feature complete and I don't expect the general outlines +to change much, but you can't judge an API's ergonomics until you +actually document and use it, so I'd expect some changes in the +details. + +*How do I try it?* + +.. code-block:: sh + + $ pip install h11 + $ git clone git@github.com:python-hyper/h11 + $ cd h11/examples + $ python basic-client.py + +and go from there. + +*License?* + +MIT + +*Code of conduct?* + +Contributors are requested to follow our `code of conduct +`_ in +all project spaces. diff --git a/venv/lib/python3.12/site-packages/h11-0.16.0.dist-info/RECORD b/venv/lib/python3.12/site-packages/h11-0.16.0.dist-info/RECORD new file mode 100644 index 0000000..a8f8e63 --- /dev/null +++ b/venv/lib/python3.12/site-packages/h11-0.16.0.dist-info/RECORD @@ -0,0 +1,29 @@ +h11-0.16.0.dist-info/INSTALLER,sha256=zuuue4knoyJ-UwPPXg8fezS7VCrXJQrAP7zeNuwvFQg,4 +h11-0.16.0.dist-info/METADATA,sha256=KPMmCYrAn8unm48YD5YIfIQf4kViFct7hyqcfVzRnWQ,8348 +h11-0.16.0.dist-info/RECORD,, +h11-0.16.0.dist-info/WHEEL,sha256=CmyFI0kx5cdEMTLiONQRbGQwjIoR1aIYB7eCAQ4KPJ0,91 +h11-0.16.0.dist-info/licenses/LICENSE.txt,sha256=N9tbuFkm2yikJ6JYZ_ELEjIAOuob5pzLhRE4rbjm82E,1124 +h11-0.16.0.dist-info/top_level.txt,sha256=F7dC4jl3zeh8TGHEPaWJrMbeuoWbS379Gwdi-Yvdcis,4 +h11/__init__.py,sha256=iO1KzkSO42yZ6ffg-VMgbx_ZVTWGUY00nRYEWn-s3kY,1507 +h11/__pycache__/__init__.cpython-312.pyc,, +h11/__pycache__/_abnf.cpython-312.pyc,, +h11/__pycache__/_connection.cpython-312.pyc,, +h11/__pycache__/_events.cpython-312.pyc,, +h11/__pycache__/_headers.cpython-312.pyc,, +h11/__pycache__/_readers.cpython-312.pyc,, +h11/__pycache__/_receivebuffer.cpython-312.pyc,, +h11/__pycache__/_state.cpython-312.pyc,, +h11/__pycache__/_util.cpython-312.pyc,, +h11/__pycache__/_version.cpython-312.pyc,, +h11/__pycache__/_writers.cpython-312.pyc,, +h11/_abnf.py,sha256=ybixr0xsupnkA6GFAyMubuXF6Tc1lb_hF890NgCsfNc,4815 +h11/_connection.py,sha256=k9YRVf6koZqbttBW36xSWaJpWdZwa-xQVU9AHEo9DuI,26863 +h11/_events.py,sha256=I97aXoal1Wu7dkL548BANBUCkOIbe-x5CioYA9IBY14,11792 +h11/_headers.py,sha256=P7D-lBNxHwdLZPLimmYwrPG-9ZkjElvvJZJdZAgSP-4,10412 +h11/_readers.py,sha256=a4RypORUCC3d0q_kxPuBIM7jTD8iLt5X91TH0FsduN4,8590 +h11/_receivebuffer.py,sha256=xrspsdsNgWFxRfQcTXxR8RrdjRXXTK0Io5cQYWpJ1Ws,5252 +h11/_state.py,sha256=_5LG_BGR8FCcFQeBPH-TMHgm_-B-EUcWCnQof_9XjFE,13231 +h11/_util.py,sha256=LWkkjXyJaFlAy6Lt39w73UStklFT5ovcvo0TkY7RYuk,4888 +h11/_version.py,sha256=GVSsbPSPDcOuF6ptfIiXnVJoaEm3ygXbMnqlr_Giahw,686 +h11/_writers.py,sha256=oFKm6PtjeHfbj4RLX7VB7KDc1gIY53gXG3_HR9ltmTA,5081 +h11/py.typed,sha256=sow9soTwP9T_gEAQSVh7Gb8855h04Nwmhs2We-JRgZM,7 diff --git a/venv/lib/python3.12/site-packages/h11-0.16.0.dist-info/WHEEL b/venv/lib/python3.12/site-packages/h11-0.16.0.dist-info/WHEEL new file mode 100644 index 0000000..1eb3c49 --- /dev/null +++ b/venv/lib/python3.12/site-packages/h11-0.16.0.dist-info/WHEEL @@ -0,0 +1,5 @@ +Wheel-Version: 1.0 +Generator: setuptools (78.1.0) +Root-Is-Purelib: true +Tag: py3-none-any + diff --git a/venv/lib/python3.12/site-packages/h11-0.16.0.dist-info/licenses/LICENSE.txt b/venv/lib/python3.12/site-packages/h11-0.16.0.dist-info/licenses/LICENSE.txt new file mode 100644 index 0000000..8f080ea --- /dev/null +++ b/venv/lib/python3.12/site-packages/h11-0.16.0.dist-info/licenses/LICENSE.txt @@ -0,0 +1,22 @@ +The MIT License (MIT) + +Copyright (c) 2016 Nathaniel J.

For +# example, we can have a (Response, _SWITCH_CONNECT) event, which is +# different from a regular Response event. +# +# 3) The keep-alive machine sees the process_keep_alive_disabled() event +# (which is derived from Request/Response events), and this event +# transitions it from True -> False, or from False -> False. There's no way +# to transition back. +# +# 4&5) The _SWITCH_* machines transition from False->True when we get a +# Request that proposes the relevant type of switch (via +# process_client_switch_proposals), and they go from True->False when we +# get a Response that has no _SWITCH_* annotation. +# +# So that's event-triggered transitions. +# +# State-triggered transitions are less standard. What they do here is couple +# the machines together. The way this works is, when certain *joint* +# configurations of states are achieved, then we automatically transition to a +# new *joint* state. So, for example, if we're ever in a joint state with +# +# client: DONE +# keep-alive: False +# +# then the client state immediately transitions to: +# +# client: MUST_CLOSE +# +# This is fundamentally different from an event-based transition, because it +# doesn't matter how we arrived at the {client: DONE, keep-alive: False} state +# -- maybe the client transitioned SEND_BODY -> DONE, or keep-alive +# transitioned True -> False. Either way, once this precondition is satisfied, +# this transition is immediately triggered. +# +# What if two conflicting state-based transitions get enabled at the same +# time? In practice there's only one case where this arises (client DONE -> +# MIGHT_SWITCH_PROTOCOL versus DONE -> MUST_CLOSE), and we resolve it by +# explicitly prioritizing the DONE -> MIGHT_SWITCH_PROTOCOL transition. +# +# Implementation +# -------------- +# +# The event-triggered transitions for the server and client machines are all +# stored explicitly in a table. Ditto for the state-triggered transitions that +# involve just the server and client state. +# +# The transitions for the other machines, and the state-triggered transitions +# that involve the other machines, are written out as explicit Python code. +# +# It'd be nice if there were some cleaner way to do all this. This isn't +# *too* terrible, but I feel like it could probably be better. +# +# WARNING +# ------- +# +# The script that generates the state machine diagrams for the docs knows how +# to read out the EVENT_TRIGGERED_TRANSITIONS and STATE_TRIGGERED_TRANSITIONS +# tables. But it can't automatically read the transitions that are written +# directly in Python code. So if you touch those, you need to also update the +# script to keep it in sync! +from typing import cast, Dict, Optional, Set, Tuple, Type, Union + +from ._events import * +from ._util import LocalProtocolError, Sentinel + +# Everything in __all__ gets re-exported as part of the h11 public API. +__all__ = [ + "CLIENT", + "SERVER", + "IDLE", + "SEND_RESPONSE", + "SEND_BODY", + "DONE", + "MUST_CLOSE", + "CLOSED", + "MIGHT_SWITCH_PROTOCOL", + "SWITCHED_PROTOCOL", + "ERROR", +] + + +class CLIENT(Sentinel, metaclass=Sentinel): + pass + + +class SERVER(Sentinel, metaclass=Sentinel): + pass + + +# States +class IDLE(Sentinel, metaclass=Sentinel): + pass + + +class SEND_RESPONSE(Sentinel, metaclass=Sentinel): + pass + + +class SEND_BODY(Sentinel, metaclass=Sentinel): + pass + + +class DONE(Sentinel, metaclass=Sentinel): + pass + + +class MUST_CLOSE(Sentinel, metaclass=Sentinel): + pass + + +class CLOSED(Sentinel, metaclass=Sentinel): + pass + + +class ERROR(Sentinel, metaclass=Sentinel): + pass + + +# Switch types +class MIGHT_SWITCH_PROTOCOL(Sentinel, metaclass=Sentinel): + pass + + +class SWITCHED_PROTOCOL(Sentinel, metaclass=Sentinel): + pass + + +class _SWITCH_UPGRADE(Sentinel, metaclass=Sentinel): + pass + + +class _SWITCH_CONNECT(Sentinel, metaclass=Sentinel): + pass + + +EventTransitionType = Dict[ + Type[Sentinel], + Dict[ + Type[Sentinel], + Dict[Union[Type[Event], Tuple[Type[Event], Type[Sentinel]]], Type[Sentinel]], + ], +] + +EVENT_TRIGGERED_TRANSITIONS: EventTransitionType = { + CLIENT: { + IDLE: {Request: SEND_BODY, ConnectionClosed: CLOSED}, + SEND_BODY: {Data: SEND_BODY, EndOfMessage: DONE}, + DONE: {ConnectionClosed: CLOSED}, + MUST_CLOSE: {ConnectionClosed: CLOSED}, + CLOSED: {ConnectionClosed: CLOSED}, + MIGHT_SWITCH_PROTOCOL: {}, + SWITCHED_PROTOCOL: {}, + ERROR: {}, + }, + SERVER: { + IDLE: { + ConnectionClosed: CLOSED, + Response: SEND_BODY, + # Special case: server sees client Request events, in this form + (Request, CLIENT): SEND_RESPONSE, + }, + SEND_RESPONSE: { + InformationalResponse: SEND_RESPONSE, + Response: SEND_BODY, + (InformationalResponse, _SWITCH_UPGRADE): SWITCHED_PROTOCOL, + (Response, _SWITCH_CONNECT): SWITCHED_PROTOCOL, + }, + SEND_BODY: {Data: SEND_BODY, EndOfMessage: DONE}, + DONE: {ConnectionClosed: CLOSED}, + MUST_CLOSE: {ConnectionClosed: CLOSED}, + CLOSED: {ConnectionClosed: CLOSED}, + SWITCHED_PROTOCOL: {}, + ERROR: {}, + }, +} + +StateTransitionType = Dict[ + Tuple[Type[Sentinel], Type[Sentinel]], Dict[Type[Sentinel], Type[Sentinel]] +] + +# NB: there are also some special-case state-triggered transitions hard-coded +# into _fire_state_triggered_transitions below. +STATE_TRIGGERED_TRANSITIONS: StateTransitionType = { + # (Client state, Server state) -> new states + # Protocol negotiation + (MIGHT_SWITCH_PROTOCOL, SWITCHED_PROTOCOL): {CLIENT: SWITCHED_PROTOCOL}, + # Socket shutdown + (CLOSED, DONE): {SERVER: MUST_CLOSE}, + (CLOSED, IDLE): {SERVER: MUST_CLOSE}, + (ERROR, DONE): {SERVER: MUST_CLOSE}, + (DONE, CLOSED): {CLIENT: MUST_CLOSE}, + (IDLE, CLOSED): {CLIENT: MUST_CLOSE}, + (DONE, ERROR): {CLIENT: MUST_CLOSE}, +} + + +class ConnectionState: + def __init__(self) -> None: + # Extra bits of state that don't quite fit into the state model. + + # If this is False then it enables the automatic DONE -> MUST_CLOSE + # transition.

Timeout dictionary. +* response: `http_version` - Optional. Include the HTTP version used on the response. +* response: `reason` - Optional. Include the reason phrase used on the response. Only valid with HTTP/1.*. + +See https://github.com/encode/httpx/issues/1274#issuecomment-694884553 for the history behind this. + +Secondly, the async version of `request` is now namespaced as `arequest`. + +This allows concrete transports to support both sync and async implementations on the same class. + +### Added + +- Add curio support. (Pull #168) +- Add anyio support, with `backend="anyio"`. (Pull #169) + +### Changed + +- Update the Transport API to use 'ext' for optional extensions.

(Pull #164) + +## 0.10.1 (August 7th, 2020) + +- Include `max_keepalive_connections` on `AsyncHTTPProxy`/`SyncHTTPProxy` classes. + +## 0.10.0 (August 7th, 2020) + +The most notable change in the 0.10.0 release is that HTTP/2 support is now fully optional. + +Use either `pip install httpcore` for HTTP/1.1 support only, or `pip install httpcore[http2]` for HTTP/1.1 and HTTP/2 support. + +### Added + +- HTTP/2 support becomes optional. (Pull #121, #130) +- Add `local_address=...` support. (Pull #100, #134) +- Add `PlainByteStream`, `IteratorByteStream`, `AsyncIteratorByteStream`.

(Pull #112) + +## 0.9.1 (May 27th, 2020) + +### Fixed + +- Proper host resolution for sync case, including IPv6 support. (Pull #97) +- Close outstanding connections when connection pool is closed. (Pull #98) + +## 0.9.0 (May 21th, 2020) + +### Changed + +- URL port becomes an `Optional[int]` instead of `int`. (Pull #92) + +### Fixed + +- Honor HTTP/2 max concurrent streams settings. (Pull #89, #90) +- Remove incorrect debug log. (Pull #83) + +## 0.8.4 (May 11th, 2020) + +### Added + +- Logging via HTTPCORE_LOG_LEVEL and HTTPX_LOG_LEVEL environment variables +and TRACE level logging.

HTTPX - A next-generation HTTP client for Python.

+ +

+ + Test Suite + + + Package version + +

+ +HTTPX is a fully featured HTTP client library for Python 3. It includes **an integrated command line client**, has support for both **HTTP/1.1 and HTTP/2**, and provides both **sync and async APIs**. + +--- + +Install HTTPX using pip: + +```shell +$ pip install httpx +``` + +Now, let's get started: + +```pycon +>>> import httpx +>>> r = httpx.get('https://www.example.org/') +>>> r + +>>> r.status_code +200 +>>> r.headers['content-type'] +'text/html; charset=UTF-8' +>>> r.text +'\n\n\nExample Domain...' +``` + +Or, using the command-line client. + +```shell +$ pip install 'httpx[cli]' # The command line client is an optional dependency. +``` + +Which now allows us to use HTTPX directly from the command-line... + +

+ httpx http://httpbin.org/json +

+ +## Features + +HTTPX builds on the well-established usability of `requests`, and gives you: + +* A broadly [requests-compatible API](https://www.python-httpx.org/compatibility/). +* An integrated command-line client. +* HTTP/1.1 [and HTTP/2 support](https://www.python-httpx.org/http2/). +* Standard synchronous interface, but with [async support if you need it](https://www.python-httpx.org/async/). +* Ability to make requests directly to [WSGI applications](https://www.python-httpx.org/advanced/transports/#wsgi-transport) or [ASGI applications](https://www.python-httpx.org/advanced/transports/#asgi-transport). +* Strict timeouts everywhere. +* Fully type annotated. +* 100% test coverage. + +Plus all the standard features of `requests`... + +* International Domains and URLs +* Keep-Alive & Connection Pooling +* Sessions with Cookie Persistence +* Browser-style SSL Verification +* Basic/Digest Authentication +* Elegant Key/Value Cookies +* Automatic Decompression +* Automatic Content Decoding +* Unicode Response Bodies +* Multipart File Uploads +* HTTP(S) Proxy Support +* Connection Timeouts +* Streaming Downloads +* .netrc Support +* Chunked Requests + +## Installation + +Install with pip: + +```shell +$ pip install httpx +``` + +Or, to include the optional HTTP/2 support, use: + +```shell +$ pip install httpx[http2] +``` + +HTTPX requires Python 3.8+. + +## Documentation + +Project documentation is available at [https://www.python-httpx.org/](https://www.python-httpx.org/). + +For a run-through of all the basics, head over to the [QuickStart](https://www.python-httpx.org/quickstart/). + +For more advanced topics, see the [Advanced Usage](https://www.python-httpx.org/advanced/) section, the [async support](https://www.python-httpx.org/async/) section, or the [HTTP/2](https://www.python-httpx.org/http2/) section. + +The [Developer Interface](https://www.python-httpx.org/api/) provides a comprehensive API reference. + +To find out about tools that integrate with HTTPX, see [Third Party Packages](https://www.python-httpx.org/third_party_packages/). + +## Contribute + +If you want to contribute with HTTPX check out the [Contributing Guide](https://www.python-httpx.org/contributing/) to learn how to start. + +## Dependencies + +The HTTPX project relies on these excellent libraries: + +* `httpcore` - The underlying transport implementation for `httpx`. + * `h11` - HTTP/1.1 support. +* `certifi` - SSL certificates. +* `idna` - Internationalized domain name support. +* `sniffio` - Async library autodetection. + +As well as these optional installs: + +* `h2` - HTTP/2 support. *(Optional, with `httpx[http2]`)* +* `socksio` - SOCKS proxy support. *(Optional, with `httpx[socks]`)* +* `rich` - Rich terminal support. *(Optional, with `httpx[cli]`)* +* `click` - Command line client support. *(Optional, with `httpx[cli]`)* +* `brotli` or `brotlicffi` - Decoding for "brotli" compressed responses. *(Optional, with `httpx[brotli]`)* +* `zstandard` - Decoding for "zstd" compressed responses. *(Optional, with `httpx[zstd]`)* + +A huge amount of credit is due to `requests` for the API layout that +much of this work follows, as well as to `urllib3` for plenty of design +inspiration around the lower-level networking details. + +--- + +

HTTPX is BSD licensed code.
Designed & crafted with care.

This library +is a suitable replacement for the “encodings.idna” +module that comes with the Python standard library, but which +only supports an older superseded IDNA specification from 2003. + +Basic functions are simply executed: + +.. code-block:: pycon + + >>> import idna + >>> idna.encode('ドメイン.テスト') + b'xn--eckwd4c7c.xn--zckzah' + >>> print(idna.decode('xn--eckwd4c7c.xn--zckzah')) + ドメイン.テスト + + +Installation +------------ + +This package is available for installation from PyPI via the +typical mechanisms, such as: + +.. code-block:: bash + + $ python3 -m pip install idna + + +Usage +----- + +For typical usage, the ``encode`` and ``decode`` functions will take a +domain name argument and perform a conversion to ASCII compatible encoding +(known as A-labels), or to Unicode strings (known as U-labels) +respectively. + +.. code-block:: pycon + + >>> import idna + >>> idna.encode('ドメイン.テスト') + b'xn--eckwd4c7c.xn--zckzah' + >>> print(idna.decode('xn--eckwd4c7c.xn--zckzah')) + ドメイン.テスト + +Conversions can be applied at a per-label basis using the ``ulabel`` or +``alabel`` functions if necessary: + +.. code-block:: pycon + + >>> idna.alabel('测试') + b'xn--0zwm56d' + + +Compatibility Mapping (UTS #46) ++++++++++++++++++++++++++++++++ + +This library provides support for `Unicode IDNA Compatibility +Processing `_ which normalizes input from +different potential ways a user may input a domain prior to performing the IDNA +conversion operations. This functionality, known as a +`mapping `_, is considered by the +specification to be a local user-interface issue distinct from IDNA +conversion functionality. + +For example, “Königsgäßchen” is not a permissible label as *LATIN +CAPITAL LETTER K* is not allowed (nor are capital letters in general). +UTS 46 will convert this into lower case prior to applying the IDNA +conversion. + +.. code-block:: pycon + + >>> import idna + >>> idna.encode('Königsgäßchen') + ... + idna.core.InvalidCodepoint: Codepoint U+004B at position 1 of 'Königsgäßchen' not allowed + >>> idna.encode('Königsgäßchen', uts46=True) + b'xn--knigsgchen-b4a3dun' + >>> print(idna.decode('xn--knigsgchen-b4a3dun')) + königsgäßchen + + +Exceptions +---------- + +All errors raised during the conversion following the specification +should raise an exception derived from the ``idna.IDNAError`` base +class. + +More specific exceptions that may be generated as ``idna.IDNABidiError`` +when the error reflects an illegal combination of left-to-right and +right-to-left characters in a label; ``idna.InvalidCodepoint`` when +a specific codepoint is an illegal character in an IDN label (i.e. +INVALID); and ``idna.InvalidCodepointContext`` when the codepoint is +illegal based on its position in the string (i.e. it is CONTEXTO or CONTEXTJ +but the contextual requirements are not satisfied.) + +Building and Diagnostics +------------------------ + +The IDNA and UTS 46 functionality relies upon pre-calculated lookup +tables for performance. These tables are derived from computing against +eligibility criteria in the respective standards using the command-line +script ``tools/idna-data``. + +This tool will fetch relevant codepoint data from the Unicode repository +and perform the required calculations to identify eligibility. There are +three main modes: + +* ``idna-data make-libdata``. Generates ``idnadata.py`` and + ``uts46data.py``, the pre-calculated lookup tables used for IDNA and + UTS 46 conversions. Implementers who wish to track this library against + a different Unicode version may use this tool to manually generate a + different version of the ``idnadata.py`` and ``uts46data.py`` files. + +* ``idna-data make-table``. Generate a table of the IDNA disposition + (e.g. PVALID, CONTEXTJ, CONTEXTO) in the format found in Appendix + B.1 of RFC 5892 and the pre-computed tables published by `IANA + `_. + +* ``idna-data U+0061``. Prints debugging output on the various + properties associated with an individual Unicode codepoint (in this + case, U+0061), that are used to assess the IDNA and UTS 46 status of a + codepoint. This is helpful in debugging or analysis. + +The tool accepts a number of arguments, described using ``idna-data +-h``. Most notably, the ``--version`` argument allows the specification +of the version of Unicode to be used in computing the table data. For +example, ``idna-data --version 9.0.0 make-libdata`` will generate +library data against Unicode 9.0.0. + + +Additional Notes +---------------- + +* **Packages**. The latest tagged release version is published in the + `Python Package Index `_. + +* **Version support**. This library supports Python 3.8 and higher. + As this library serves as a low-level toolkit for a variety of + applications, many of which strive for broad compatibility with older + Python versions, there is no rush to remove older interpreter support. + Support for older versions are likely to be removed from new releases + as automated tests can no longer easily be run, i.e. once the Python + version is officially end-of-life. + +* **Testing**. The library has a test suite based on each rule of the + IDNA specification, as well as tests that are provided as part of the + Unicode Technical Standard 46, `Unicode IDNA Compatibility Processing + `_. + +* **Emoji**. It is an occasional request to support emoji domains in + this library. Encoding of symbols like emoji is expressly prohibited by + the technical standard IDNA 2008 and emoji domains are broadly phased + out across the domain industry due to associated security risks. For + now, applications that need to support these non-compliant labels + may wish to consider trying the encode/decode operation in this library + first, and then falling back to using `encodings.idna`. See `the Github + project `_ for more discussion. + +* **Transitional processing**. Unicode 16.0.0 removed transitional + processing so the `transitional` argument for the encode() method + no longer has any effect and will be removed at a later date. + diff --git a/venv/lib/python3.12/site-packages/idna-3.11.dist-info/RECORD b/venv/lib/python3.12/site-packages/idna-3.11.dist-info/RECORD new file mode 100644 index 0000000..8525b6d --- /dev/null +++ b/venv/lib/python3.12/site-packages/idna-3.11.dist-info/RECORD @@ -0,0 +1,22 @@ +idna-3.11.dist-info/INSTALLER,sha256=zuuue4knoyJ-UwPPXg8fezS7VCrXJQrAP7zeNuwvFQg,4 +idna-3.11.dist-info/METADATA,sha256=fCwSww9SuiN8TIHllFSASUQCW55hAs8dzKnr9RaEEbA,8378 +idna-3.11.dist-info/RECORD,, +idna-3.11.dist-info/WHEEL,sha256=G2gURzTEtmeR8nrdXUJfNiB3VYVxigPQ-bEQujpNiNs,82 +idna-3.11.dist-info/licenses/LICENSE.md,sha256=t6M2q_OwThgOwGXN0W5wXQeeHMehT5EKpukYfza5zYc,1541 +idna/__init__.py,sha256=MPqNDLZbXqGaNdXxAFhiqFPKEQXju2jNQhCey6-5eJM,868 +idna/__pycache__/__init__.cpython-312.pyc,, +idna/__pycache__/codec.cpython-312.pyc,, +idna/__pycache__/compat.cpython-312.pyc,, +idna/__pycache__/core.cpython-312.pyc,, +idna/__pycache__/idnadata.cpython-312.pyc,, +idna/__pycache__/intranges.cpython-312.pyc,, +idna/__pycache__/package_data.cpython-312.pyc,, +idna/__pycache__/uts46data.cpython-312.pyc,, +idna/codec.py,sha256=M2SGWN7cs_6B32QmKTyTN6xQGZeYQgQ2wiX3_DR6loE,3438 +idna/compat.py,sha256=RzLy6QQCdl9784aFhb2EX9EKGCJjg0P3PilGdeXXcx8,316 +idna/core.py,sha256=P26_XVycuMTZ1R2mNK1ZREVzM5mvTzdabBXfyZVU1Lc,13246 +idna/idnadata.py,sha256=SG8jhaGE53iiD6B49pt2pwTv_UvClciWE-N54oR2p4U,79623 +idna/intranges.py,sha256=amUtkdhYcQG8Zr-CoMM_kVRacxkivC1WgxN1b63KKdU,1898 +idna/package_data.py,sha256=_CUavOxobnbyNG2FLyHoN8QHP3QM9W1tKuw7eq9QwBk,21 +idna/py.typed,sha256=47DEQpj8HBSa-_TImW-5JCeuQeRkm5NMpJWZG3hSuFU,0 +idna/uts46data.py,sha256=H9J35VkD0F9L9mKOqjeNGd2A-Va6FlPoz6Jz4K7h-ps,243725 diff --git a/venv/lib/python3.12/site-packages/idna-3.11.dist-info/WHEEL b/venv/lib/python3.12/site-packages/idna-3.11.dist-info/WHEEL new file mode 100644 index 0000000..d8b9936 --- /dev/null +++ b/venv/lib/python3.12/site-packages/idna-3.11.dist-info/WHEEL @@ -0,0 +1,4 @@ +Wheel-Version: 1.0 +Generator: flit 3.12.0 +Root-Is-Purelib: true +Tag: py3-none-any diff --git a/venv/lib/python3.12/site-packages/idna-3.11.dist-info/licenses/LICENSE.md b/venv/lib/python3.12/site-packages/idna-3.11.dist-info/licenses/LICENSE.md new file mode 100644 index 0000000..256ba90 --- /dev/null +++ b/venv/lib/python3.12/site-packages/idna-3.11.dist-info/licenses/LICENSE.md @@ -0,0 +1,31 @@ +BSD 3-Clause License + +Copyright (c) 2013-2025, Kim Davies and contributors. +All rights reserved. + +Redistribution and use in source and binary forms, with or without +modification, are permitted provided that the following conditions are +met: + +1.

license-file + +========================= +Mako Templates for Python +========================= + +Mako is a template library written in Python. It provides a familiar, non-XML +syntax which compiles into Python modules for maximum performance. Mako's +syntax and API borrows from the best ideas of many others, including Django +templates, Cheetah, Myghty, and Genshi. Conceptually, Mako is an embedded +Python (i.e. Python Server Page) language, which refines the familiar ideas +of componentized layout and inheritance to produce one of the most +straightforward and flexible models available, while also maintaining close +ties to Python calling and scoping semantics. + +Nutshell +======== + +:: + + <%inherit file="base.html"/> + <% + rows = [[v for v in range(0,10)] for row in range(0,10)] + %> + + % for row in rows: + ${makerow(row)} + % endfor +
+ + <%def name="makerow(row)"> + + % for name in row: + ${name}\ + % endfor + + + +Philosophy +=========== + +Python is a great scripting language. Don't reinvent the wheel...your templates can handle it ! + +Documentation +============== + +See documentation for Mako at https://docs.makotemplates.org/en/latest/ + +License +======== + +Mako is

+Package resource API
+--------------------
+
+A resource is a logical file contained within a package, or a logical
+subdirectory thereof.  The package resource API expects resource names
+to have their path parts separated with ``/``, *not* whatever the local
+path separator is.  Do not use os.path operations to manipulate resource
+names being passed into the API.
+
+The package resource API is designed to work with normal filesystem packages,
+.egg files, and unpacked .egg files.  It can also work in a limited way with
+.zip files and with custom PEP 302 loaders that support the ``get_data()``
+method.
+
+This module is deprecated. Users are directed to :mod:`importlib.resources`,
+:mod:`importlib.metadata` and :pypi:`packaging` instead.

+    Pygments
+    ~~~~~~~~
+
+    Pygments is a syntax highlighting package written in Python.
+
+    It is a generic syntax highlighter for general use in all kinds of software
+    such as forum systems, wikis or other applications that need to prettify
+    source code. Highlights are:
+
+    * a wide range of common languages and markup formats is supported
+    * special attention is paid to details, increasing quality by a fair amount
+    * support for new languages and formats are added easily
+    * a number of output formats, presently HTML, LaTeX, RTF, SVG, all image
+      formats that PIL supports, and ANSI sequences
+    * it is usable as a command-line tool and as a library
+    * ... and it highlights even Brainfuck!
+
+    The `Pygments master branch`_ is installable with ``easy_install Pygments==dev``.
