+# 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>')
+```

+            name for a more meaningful ``repr`` output.  This argument is
+            pointless in Python 3 and is therefore deprecated.
+
+    .. caution::
+        Refer to `attrs.define` for the rest of the parameters, but note that they
+        can have different defaults.
+
+        Notably, leaving *on_setattr* as `None` will **not** add any hooks.

+    A class decorator that adds :term:`dunder methods` according to
+    :term:`fields <field>` specified using :doc:`type annotations <types>`,
+    `field()` calls, or the *these* argument.
+
+    Since *attrs* patches or replaces an existing class, you cannot use
+    `object.__init_subclass__` with *attrs* classes, because it runs too early.
+    As a replacement, you can define ``__attrs_init_subclass__`` on your class.
+    It will be called by *attrs* classes that subclass it after they're
+    created. See also :ref:`init-subclass`.
+
+    Args:
+        slots (bool):
+            Create a :term:`slotted class <slotted classes>` that's more
+            memory-efficient. Slotted classes are generally superior to the
+            default dict classes, but have some gotchas you should know about,
+            so we encourage you to read the :term:`glossary entry <slotted
+            classes>`.
+
+        auto_detect (bool):
+            Instead of setting the *init*, *repr*, *eq*, and *hash* arguments
+            explicitly, assume they are set to True **unless any** of the
+            involved methods for one of the arguments is implemented in the
+            *current* class (meaning, it is *not* inherited from some base
+            class).
+
+            So, for example by implementing ``__eq__`` on a class yourself,
+            *attrs* will deduce ``eq=False`` and will create *neither*
+            ``__eq__`` *nor* ``__ne__`` (but Python classes come with a
+            sensible ``__ne__`` by default, so it *should* be enough to only
+            implement ``__eq__`` in most cases).
+
+            Passing True or False` to *init*, *repr*, *eq*, or *hash*
+            overrides whatever *auto_detect* would determine.
+
+        auto_exc (bool):
+            If the class subclasses `BaseException` (which implicitly includes
+            any subclass of any exception), the following happens to behave
+            like a well-behaved Python exception class:
+
+            - the values for *eq*, *order*, and *hash* are ignored and the
+              instances compare and hash by the instance's ids [#]_ ,
+            - all attributes that are either passed into ``__init__`` or have a
+              default value are additionally available as a tuple in the
+              ``args`` attribute,
+            - the value of *str* is ignored leaving ``__str__`` to base
+              classes.
+
+            .. [#]
+               Note that *attrs* will *not* remove existing implementations of
+               ``__hash__`` or the equality methods. It just won't add own
+               ones.
+
+        on_setattr (~typing.Callable | list[~typing.Callable] | None | ~typing.Literal[attrs.setters.NO_OP]):
+            A callable that is run whenever the user attempts to set an
+            attribute (either by assignment like ``i.x = 42`` or by using
+            `setattr` like ``setattr(i, "x", 42)``). It receives the same
+            arguments as validators: the instance, the attribute that is being
+            modified, and the new value.
+
+            If no exception is raised, the attribute is set to the return value
+            of the callable.
+
+            If a list of callables is passed, they're automatically wrapped in
+            an `attrs.setters.pipe`.
+
+            If left None, the default behavior is to run converters and
+            validators whenever an attribute is set.
+
+        init (bool):
+            Create a ``__init__`` method that initializes the *attrs*
+            attributes. Leading underscores are stripped for the argument name,
+            unless an alias is set on the attribute.
+
+            .. seealso::
+                `init` shows advanced ways to customize the generated
+                ``__init__`` method, including executing code before and after.
+
+        repr(bool):
+            Create a ``__repr__`` method with a human readable representation
+            of *attrs* attributes.
+
+        str (bool):
+            Create a ``__str__`` method that is identical to ``__repr__``. This
+            is usually not necessary except for `Exception`\ s.
+
+        eq (bool | None):
+            If True or None (default), add ``__eq__`` and ``__ne__`` methods
+            that check two instances for equality.
+
+            .. seealso::
+                `comparison` describes how to customize the comparison behavior
+                going as far comparing NumPy arrays.
+
+        order (bool | None):
+            If True, add ``__lt__``, ``__le__``, ``__gt__``, and ``__ge__``
+            methods that behave like *eq* above and allow instances to be
+            ordered.
+
+            They compare the instances as if they were tuples of their *attrs*
+            attributes if and only if the types of both classes are
+            *identical*.
+
+            If `None` mirror value of *eq*.
+
+            .. seealso:: `comparison`
+
+        unsafe_hash (bool | None):
+            If None (default), the ``__hash__`` method is generated according
+            how *eq* and *frozen* are set.
+
+            1. If *both* are True, *attrs* will generate a ``__hash__`` for
+               you.
+            2. If *eq* is True and *frozen* is False, ``__hash__`` will be set
+               to None, marking it unhashable (which it is).
+            3. If *eq* is False, ``__hash__`` will be left untouched meaning
+               the ``__hash__`` method of the base class will be used. If the
+               base class is `object`, this means it will fall back to id-based
+               hashing.
+
+            Although not recommended, you can decide for yourself and force
+            *attrs* to create one (for example, if the class is immutable even
+            though you didn't freeze it programmatically) by passing True or
+            not.  Both of these cases are rather special and should be used
+            carefully.

+                - Python's documentation on `object.__hash__`,
+                - and the `GitHub issue that led to the default \ behavior
+                  <https://github.com/python-attrs/attrs/issues/136>`_ for more
+                  details.
+
+        hash (bool | None):
+            Deprecated alias for *unsafe_hash*. *unsafe_hash* takes precedence.
+
+        cache_hash (bool):
+            Ensure that the object's hash code is computed only once and stored
+            on the object.  If this is set to True, hashing must be either
+            explicitly or implicitly enabled for this class.  If the hash code
+            is cached, avoid any reassignments of fields involved in hash code
+            computation or mutations of the objects those fields point to after
+            object creation.  If such changes occur, the behavior of the
+            object's hash code is undefined.
+
+        frozen (bool):
+            Make instances immutable after initialization.  If someone attempts
+            to modify a frozen instance, `attrs.exceptions.FrozenInstanceError`
+            is raised.
+
+            .. note::
+
+                1. This is achieved by installing a custom ``__setattr__``
+                   method on your class, so you can't implement your own.
+
+                2. True immutability is impossible in Python.
+
+                3. This *does* have a minor a runtime performance `impact
+                   <how-frozen>` when initializing new instances.  In other
+                   words: ``__init__`` is slightly slower with ``frozen=True``.
+
+                4. If a class is frozen, you cannot modify ``self`` in
+                   ``__attrs_post_init__`` or a self-written ``__init__``. You
+                   can circumvent that limitation by using
+                   ``object.__setattr__(self, "attribute_name", value)``.
+
+                5. Subclasses of a frozen class are frozen too.
+
+        kw_only (bool):
+            Make all attributes keyword-only in the generated ``__init__`` (if
+            *init* is False, this parameter is ignored).
+
+        weakref_slot (bool):
+            Make instances weak-referenceable.  This has no effect unless
+            *slots* is True.
+
+        field_transformer (~typing.Callable | None):
+            A function that is called with the original class object and all
+            fields right before *attrs* finalizes the class.  You can use this,
+            for example, to automatically add converters or validators to
+            fields based on their types.
+
+            .. seealso:: `transform-fields`
+
+        match_args (bool):
+            If True (default), set ``__match_args__`` on the class to support
+            :pep:`634` (*Structural Pattern Matching*). It is a tuple of all
+            non-keyword-only ``__init__`` parameter names on Python 3.10 and
+            later. Ignored on older Python versions.
+
+        collect_by_mro (bool):
+            If True, *attrs* collects attributes from base classes correctly
+            according to the `method resolution order
+            <https://docs.python.org/3/howto/mro.html>`_. If False, *attrs*
+            will mimic the (wrong) behavior of `dataclasses` and :pep:`681`.
+
+            See also `issue #428
+            <https://github.com/python-attrs/attrs/issues/428>`_.
+
+        getstate_setstate (bool | None):
+            .. note::
+
+                This is usually only interesting for slotted classes and you
+                should probably just set *auto_detect* to True.
+
+            If True, ``__getstate__`` and ``__setstate__`` are generated and
+            attached to the class. This is necessary for slotted classes to be
+            pickleable. If left None, it's True by default for slotted classes
+            and False for dict classes.
+
+            If *auto_detect* is True, and *getstate_setstate* is left None, and
+            **either** ``__getstate__`` or ``__setstate__`` is detected
+            directly on the class (meaning: not inherited), it is set to False
+            (this is usually what you want).
+
+        auto_attribs (bool | None):
+            If True, look at type annotations to determine which attributes to
+            use, like `dataclasses`. If False, it will only look for explicit
+            :func:`field` class attributes, like classic *attrs*.
+
+            If left None, it will guess:
+
+            1. If any attributes are annotated and no unannotated
+               `attrs.field`\ s are found, it assumes *auto_attribs=True*.
+            2. Otherwise it assumes *auto_attribs=False* and tries to collect
+               `attrs.field`\ s.
+
+            If *attrs* decides to look at type annotations, **all** fields
+            **must** be annotated. If *attrs* encounters a field that is set to
+            a :func:`field` / `attr.ib` but lacks a type annotation, an
+            `attrs.exceptions.UnannotatedAttributeError` is raised.  Use
+            ``field_name: typing.Any = field(...)`` if you don't want to set a
+            type.
+
+            .. warning::
+
+                For features that use the attribute name to create decorators
+                (for example, :ref:`validators <validators>`), you still *must*
+                assign :func:`field` / `attr.ib` to them. Otherwise Python will
+                either not find the name or try to use the default value to
+                call, for example, ``validator`` on it.
+
+            Attributes annotated as `typing.ClassVar`, and attributes that are
+            neither annotated nor set to an `field()` are **ignored**.
+
+        these (dict[str, object]):
+            A dictionary of name to the (private) return value of `field()`
+            mappings. This is useful to avoid the definition of your attributes
+            within the class body because you can't (for example, if you want
+            to add ``__repr__`` methods to Django models) or don't want to.
+
+            If *these* is not `None`, *attrs* will *not* search the class body
+            for attributes and will *not* remove any attributes from it.
+
+            The order is deduced from the order of the attributes inside
+            *these*.
+
+            Arguably, this is a rather obscure feature.
+
+    .. versionadded:: 20.1.0
+    .. versionchanged:: 21.3.0 Converters are also run ``on_setattr``.
+    .. versionadded:: 22.2.0
+       *unsafe_hash* as an alias for *hash* (for :pep:`681` compliance).
+    .. versionchanged:: 24.1.0
+       Instances are not compared as tuples of attributes anymore, but using a
+       big ``and`` condition. This is faster and has more correct behavior for
+       uncomparable values like `math.nan`.
+    .. versionadded:: 24.1.0
+       If a class has an *inherited* classmethod called
+       ``__attrs_init_subclass__``, it is executed after the class is created.
+    .. deprecated:: 24.1.0 *hash* is deprecated in favor of *unsafe_hash*.
+    .. versionadded:: 24.3.0
+       Unless already present, a ``__replace__`` method is automatically
+       created for `copy.replace` (Python 3.13+ only).
+
+    .. note::
+
+        The main differences to the classic `attr.s` are:
+
+        - Automatically detect whether or not *auto_attribs* should be `True`
+          (c.f. *auto_attribs* parameter).
+        - Converters and validators run when attributes are set by default --
+          if *frozen* is `False`.
+        - *slots=True*
+
+          Usually, this has only upsides and few visible effects in everyday
+          programming. But it *can* lead to some surprising behaviors, so
+          please make sure to read :term:`slotted classes`.
+
+        - *auto_exc=True*
+        - *auto_detect=True*
+        - *order=False*
+        - Some options that were only relevant on Python 2 or were kept around
+          for backwards-compatibility have been removed.
