Also includes a few other miscellaneous string manipulation functions that have crept in over time. Many functions in this module have near-equivalents in the standard library (the differences mainly relate to handling of bytes and unicode strings, and were more relevant in Python 2). In new code, the standard library functions are encouraged instead of this module where applicable. See the docstrings on each function for details. � N)� unicode_type)�Union�Any�Optional�Dict�List�Callable�value�returnc C � t �t| ��S )a� Escapes a string so it is valid within HTML or XML. Escapes the characters ``<``, ``>``, ``"``, ``'``, and ``&``. When used in attribute values the escaped strings must be enclosed in quotes. Equivalent to `html.escape` except that this function always returns type `str` while `html.escape` returns `bytes` if its input is `bytes`. .. versionchanged:: 3.2 Added the single quote to the list of escaped characters. .. versionchanged:: 6.4 Now simply wraps `html.escape`. This is equivalent to the old behavior except that single quotes are now escaped as ``'`` instead of ``'`` and performance may be different. )�html�escape� to_unicode�r � r �D/usr/local/CyberPanel/lib/python3.10/site-packages/tornado/escape.py� xhtml_escape' s r c C r )aZ Un-escapes an XML-escaped string. Equivalent to `html.unescape` except that this function always returns type `str` while `html.unescape` returns `bytes` if its input is `bytes`. .. versionchanged:: 6.4 Now simply wraps `html.unescape`. This changes behavior for some inputs as required by the HTML 5 specification https://html.spec.whatwg.org/multipage/parsing.html#numeric-character-reference-end-state Some invalid inputs such as surrogates now raise an error, and numeric references to certain ISO-8859-1 characters are now handled correctly. )r �unescaper r r r r �xhtml_unescape> s r c C s t �| ��dd�S )z�JSON-encodes the given Python object.

Equivalent to either `urllib.parse.quote_plus` or `urllib.parse.quote` depending on the ``plus`` argument. If ``plus`` is true (the default), spaces will be represented as ``+`` and slashes will be represented as ``%2F``. This is appropriate for query strings. If ``plus`` is false, spaces will be represented as ``%20`` and slashes are left as-is. This is appropriate for the path component of a URL. Note that the default of ``plus=True`` is effectively the reverse of Python's urllib module. .. versionadded:: 3.1 The ``plus`` argument )�urllib�parse� quote_plus�quote)r r r$ r r r � url_escapep s r% �encodingc C � d S �Nr �r r& r r r r � url_unescape� � r* �utf-8c C r' r( r r) r r r r* � s c C sL |du r|rt | ��dd�} tj�| �S |rtjjntjj}|t | �|d�S )aO Decodes the given value from a URL. The argument may be either a byte or unicode string. If encoding is None, the result will be a byte string and this function is equivalent to `urllib.parse.unquote_to_bytes` if ``plus=False``. Otherwise, the result is a unicode string in the specified encoding and this function is equivalent to either `urllib.parse.unquote_plus` or `urllib.parse.unquote` except that this function also accepts `bytes` as input. If ``plus`` is true (the default), plus signs will be interpreted as spaces (literal plus signs must be represented as "%2B"). This is appropriate for query strings and form-encoded values but not for the path component of a URL.

If this is False, urls such as www.facebook.com will also be linkified. * ``permitted_protocols``: List (or set) of protocols which should be linkified, e.g. ``linkify(text, permitted_protocols=["http", "ftp", "mailto"])``.
