+
+Flask-Login provides user session management for Flask. It handles the common
+tasks of logging in, logging out, and remembering your users' sessions over
+extended periods of time.
+
+Flask-Login is not bound to any particular database system or permissions
+model. The only requirement is that your user objects implement a few methods,
+and that you provide a callback to the extension capable of loading users from
+their ID.
+
+## Installation
+
+Install the extension with pip:
+
+```sh
+$ pip install flask-login
+```
+
+## Usage
+
+Once installed, the Flask-Login is easy to use. Let's walk through setting up
+a basic application. Also please note that this is a very basic guide: we will
+be taking shortcuts here that you should never take in a real application.
+
+To begin we'll set up a Flask app:
+
+```python
+import flask
+
+app = flask.Flask(__name__)
+app.secret_key = 'super secret string'  # Change this!
+```
+
+Flask-Login works via a login manager. To kick things off, we'll set up the
+login manager by instantiating it and telling it about our Flask app:
+
+```python
+import flask_login
+
+login_manager = flask_login.LoginManager()
+
+login_manager.init_app(app)
+```
+
+To keep things simple we're going to use a dictionary to represent a database
+of users. In a real application, this would be an actual persistence layer.
+However it's important to point out this is a feature of Flask-Login: it
+doesn't care how your data is stored so long as you tell it how to retrieve it!
+
+```python
+# Our mock database.
+users = {'foo@bar.tld': {'password': 'secret'}}
+```
+
+We also need to tell Flask-Login how to load a user from a Flask request and
+from its session. To do this we need to define our user object, a
+`user_loader` callback, and a `request_loader` callback.
+
+```python
+class User(flask_login.UserMixin):
+    pass
+
+
+@login_manager.user_loader
+def user_loader(email):
+    if email not in users:
+        return
+
+    user = User()
+    user.id = email
+    return user
+
+
+@login_manager.request_loader
+def request_loader(request):
+    email = request.form.get('email')
+    if email not in users:
+        return
+
+    user = User()
+    user.id = email
+    return user
+```
+
+Now we're ready to define our views. We can start with a login view, which will
+populate the session with authentication bits. After that we can define a view
+that requires authentication.
+
+```python
+@app.route('/login', methods=['GET', 'POST'])
+def login():
+    if flask.request.method == 'GET':
+        return '''
+               <form action='login' method='POST'>
+                <input type='text' name='email' id='email' placeholder='email'/>
+                <input type='password' name='password' id='password' placeholder='password'/>
+                <input type='submit' name='submit'/>
+               </form>
+               '''
+
+    email = flask.request.form['email']
+    if email in users and flask.request.form['password'] == users[email]['password']:
+        user = User()
+        user.id = email
+        flask_login.login_user(user)
+        return flask.redirect(flask.url_for('protected'))
+
+    return 'Bad login'
+
+
+@app.route('/protected')
+@flask_login.login_required
+def protected():
+    return 'Logged in as: ' + flask_login.current_user.id
+```
+
+Finally we can define a view to clear the session and log users out:
+
+```python
+@app.route('/logout')
+def logout():
+    flask_login.logout_user()
+    return 'Logged out'
+```
+
+We now have a basic working application that makes use of session-based
+authentication. To round things off, we should provide a callback for login
+failures:
+
+```python
+@login_manager.unauthorized_handler
+def unauthorized_handler():
+    return 'Unauthorized', 401
+```
+
+Documentation for Flask-Login is available on [ReadTheDocs](https://flask-login.readthedocs.io/en/latest/).

+# MarkupSafe
+
+MarkupSafe implements a text object that escapes characters so it is
+safe to use in HTML and XML. Characters that have special meanings are
+replaced so that they display as the actual characters. This mitigates
+injection attacks, meaning untrusted user input can safely be displayed
+on a page.
+
+
+## Examples
+
+```pycon
+>>> from markupsafe import Markup, escape
+
+>>> # escape replaces special characters and wraps in Markup
+>>> escape("<script>alert(document.cookie);</script>")
+Markup('&lt;script&gt;alert(document.cookie);&lt;/script&gt;')
+
+>>> # wrap in Markup to mark text "safe" and prevent escaping
+>>> Markup("<strong>Hello</strong>")
+Markup('<strong>hello</strong>')
+
+>>> escape(Markup("<strong>Hello</strong>"))
+Markup('<strong>hello</strong>')
+
+>>> # Markup is a str subclass
+>>> # methods and operators escape their arguments
+>>> template = Markup("Hello <em>{name}</em>")
+>>> template.format(name='"World"')
+Markup('Hello <em>&#34;World&#34;</em>')
+```

+constraints such as upper and lower bounds on scalar values and collection sizes,
+a `Predicate` marker for runtime checks, and
+descriptions of how we intend these metadata to be interpreted. In some cases,
+we also note alternative representations which do not require this package.

+
+## 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. If you'd like more constraints for your
+types - follow our lead, by defining them and documenting them downstream!

+
+AnyIO is an asynchronous networking and concurrency library that works on top of either asyncio_ or
+trio_. 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.
+
+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
+* Asynchronous file I/O (using worker threads)
+* Signal handling
+
+AnyIO also comes with its own pytest_ plugin which also supports asynchronous fixtures.
+It even works with the popular Hypothesis_ library.
