u"""Hyperlink provides Pythonic URL parsing, construction, and rendering.

Usage is straightforward::

>>> import hyperlink
   >>> url = hyperlink.parse(u'http://github.com/mahmoud/hyperlink?utm_source=docs')
   >>> url.host
   u'github.com'
   >>> secure_url = url.replace(scheme=u'https')
   >>> secure_url.get('utm_source')[0]
   u'docs'

Hyperlink's API centers on the :class:`DecodedURL` type, which wraps
the lower-level :class:`URL`, both of which can be returned by the
:func:`parse()` convenience function.

    """Decode a host from ASCII-encodable text to IDNA-decoded text. If
    the host text is not ASCII, it is returned unchanged, as it is
    presumed that it is already IDNA-decoded.

Some technical details: _decode_host is built on top of the "idna"
    package, which has some quirks:

Capital letters are not valid IDNA2008. The idna package will
    raise an exception like this on capital letters:

> idna.core.InvalidCodepoint: Codepoint U+004B at position 1 ... not allowed

However, if a segment of a host (i.e., something in
    url.host.split('.')) is already ASCII, idna doesn't perform its
    usual checks. In fact, for capital letters it automatically
    lowercases them.

This check and some other functionality can be bypassed by passing
    uts46=True to idna.encode/decode. This allows a more permissive and
    convenient interface. So far it seems like the balanced approach.

Example output (from idna==2.6):

class URL(object):
    r"""From blogs to billboards, URLs are so common, that it's easy to
    overlook their complexity and power. With hyperlink's
    :class:`URL` type, working with URLs doesn't have to be hard.

URLs are made of many parts. Most of these parts are officially
    named in `RFC 3986`_ and this diagram may prove handy in identifying
    them::

foo://user:pass@example.com:8042/over/there?name=ferret#nose
       \_/   \_______/ \_________/ \__/\_________/ \_________/ \__/
        |        |          |        |      |           |        |
      scheme  userinfo     host     port   path       query   fragment

While :meth:`~URL.from_text` is used for parsing whole URLs, the
    :class:`URL` constructor builds a URL from the individual
    components, like so::

>>> from hyperlink import URL
        >>> url = URL(scheme=u'https', host=u'example.com', path=[u'hello', u'world'])
        >>> print(url.to_text())
        https://example.com/hello/world

The constructor runs basic type checks. All strings are expected
    to be text (:class:`str` in Python 3, :class:`unicode` in Python 2). All
    arguments are optional, defaulting to appropriately empty values. A full
    list of constructor arguments is below.

Args:
        scheme: The text name of the scheme.
        host: The host portion of the network location
        port: The port part of the network location. If ``None`` or no port is
            passed, the port will default to the default port of the scheme, if
            it is known. See the ``SCHEME_PORT_MAP`` and
            :func:`register_default_port` for more info.
        path: A tuple of strings representing the slash-separated parts of the
            path, each percent-encoded.
        query: The query parameters, as a dictionary or as an sequence of
            percent-encoded key-value pairs.
        fragment: The fragment part of the URL.
        rooted: A rooted URL is one which indicates an absolute path.
            This is True on any URL that includes a host, or any relative URL
            that starts with a slash.
        userinfo: The username or colon-separated username:password pair.
        uses_netloc: Indicates whether ``://`` (the "netloc separator") will
            appear to separate the scheme from the *path* in cases where no
            host is present.
            Setting this to ``True`` is a non-spec-compliant affordance for the
            common practice of having URIs that are *not* URLs (cannot have a
            'host' part) but nevertheless use the common ``://`` idiom that
            most people associate with URLs; e.g. ``message:`` URIs like
            ``message://message-id`` being equivalent to ``message:message-id``.
            This may be inferred based on the scheme depending on whether
            :func:`register_scheme` has been used to register the scheme and
            should not be passed directly unless you know the scheme works like
            this and you know it has not been registered.

All of these parts are also exposed as read-only attributes of :class:`URL`
    instances, along with several useful methods.

    :class:`DecodedURL` is a type designed to act as a higher-level
    interface to :class:`URL` and the recommended type for most
    operations. By analogy, :class:`DecodedURL` is the
    :class:`unicode` to URL's :class:`bytes`.

:class:`DecodedURL` automatically handles encoding and decoding
    all its components, such that all inputs and outputs are in a
    maximally-decoded state.  Note that this means, for some special
    cases, a URL may not "roundtrip" character-for-character, but this
    is considered a good tradeoff for the safety of automatic
    encoding.

Otherwise, :class:`DecodedURL` has almost exactly the same API as
    :class:`URL`.

Where applicable, a UTF-8 encoding is presumed. Be advised that
    some interactions can raise :exc:`UnicodeEncodeErrors` and
    :exc:`UnicodeDecodeErrors`, just like when working with
    bytestrings. Examples of such interactions include handling query
    strings encoding binary data, and paths containing segments with
    special characters encoded with codecs other than UTF-8.

Args:
        url: A :class:`URL` object to wrap.
        lazy: Set to True to avoid pre-decode all parts of the URL to check for
            validity.
            Defaults to False.
        query_plus_is_space: + characters in the query string should be treated
            as spaces when decoding.  If unspecified, the default is taken from
            the scheme.

.. note::

The :class:`DecodedURL` initializer takes a :class:`URL` object,
      not URL components, like :class:`URL`. To programmatically
      construct a :class:`DecodedURL`, you can use this pattern:

>>> print(DecodedURL().replace(scheme=u'https',
        ... host=u'pypi.org', path=(u'projects', u'hyperlink')).to_text())
