Introduction
------------
Url is constructed from ``str``:
.. code-block:: pycon
>>> from yarl import URL
>>> url = URL('https://www.python.org/~guido?arg=1#frag')
>>> url
URL('https://www.python.org/~guido?arg=1#frag')
All url parts: *scheme*, *user*, *password*, *host*, *port*, *path*,
*query* and *fragment* are accessible by properties:
.. code-block:: pycon
>>> url.scheme
'https'
>>> url.host
'www.python.org'
>>> url.path
'/~guido'
>>> url.query_string
'arg=1'
>>> url.query
<MultiDictProxy('arg': '1')>
>>> url.fragment
'frag'
All url manipulations produce a new url object:
.. code-block:: pycon
>>> url = URL('https://www.python.org')
>>> url / 'foo' / 'bar'
URL('https://www.python.org/foo/bar')
>>> url / 'foo' % {'bar': 'baz'}
URL('https://www.python.org/foo?bar=baz')
Strings passed to constructor and modification methods are
automatically encoded giving canonical representation as result:
.. code-block:: pycon
>>> url = URL('https://www.python.org/путь')
>>> url
URL('https://www.python.org/%D0%BF%D1%83%D1%82%D1%8C')
Regular properties are *percent-decoded*, use ``raw_`` versions for
getting *encoded* strings:
.. code-block:: pycon
>>> url.path
'/путь'
>>> url.raw_path
'/%D0%BF%D1%83%D1%82%D1%8C'
Human readable representation of URL is available as ``.human_repr()``:
.. code-block:: pycon
>>> url.human_repr()
'https://www.python.org/путь'
For full documentation please read https://yarl.readthedocs.org.
Installation
------------
::
$ pip install yarl
The library is Python 3 only!
PyPI contains binary wheels for Linux, Windows and MacOS. If you want to install
``yarl`` on another operating system (like *Alpine Linux*, which is not
manylinux-compliant because of the missing glibc and therefore, cannot be
used with our wheels) the the tarball will be used to compile the library from
the source code. It requires a C compiler and and Python headers installed.
To skip the compilation you must explicitly opt-in by setting the `YARL_NO_EXTENSIONS`
environment variable to a non-empty value, e.g.:
.. code-block:: bash
$ YARL_NO_EXTENSIONS=1 pip install yarl
Please note that the pure-Python (uncompiled) version is much slower. However,
PyPy always uses a pure-Python implementation, and, as such, it is unaffected
by this variable.
Dependencies
------------
YARL requires multidict_ library.
API documentation
------------------
The documentation is located at https://yarl.readthedocs.org
Why isn't boolean supported by the URL query API?
-------------------------------------------------
There is no standard for boolean representation of boolean values.
Some systems prefer ``true``/``false``, others like ``yes``/``no``, ``on``/``off``,
``Y``/``N``, ``1``/``0``, etc.
``yarl`` cannot make an unambiguous decision on how to serialize ``bool`` values because
it is specific to how the end-user's application is built and would be different for
different apps. The library doesn't accept booleans in the API; a user should convert
bools into strings using own preferred translation protocol.
Comparison with other URL libraries
------------------------------------
* furl (https://pypi.python.org/pypi/furl)
The library has rich functionality but the ``furl`` object is mutable.
I'm afraid to pass this object into foreign code: who knows if the
code will modify my url in a terrible way while I just want to send URL
with handy helpers for accessing URL properties.
``furl`` has other non-obvious tricky things but the main objection
is mutability.
* URLObject (https://pypi.python.org/pypi/URLObject)
URLObject is immutable, that's pretty good.
Every URL change generates a new URL object.
But the library doesn't do any decode/encode transformations leaving the
end user to cope with these gory details.

The project is hosted on GitHub_
Please file an issue on the `bug tracker
<https://github.com/aio-libs/yarl/issues>`_ if you have found a bug
or have some suggestion in order to improve the library.
The library uses `Azure Pipelines <https://dev.azure.com/aio-libs/yarl>`_ for
Continuous Integration.

1.5.0 (2020-07-26)
==================
Features
--------
- Convert host to lowercase on URL building.
`#386 <https://github.com/aio-libs/yarl/issues/386>`_
- Allow using ``mod`` operator (`%`) for updating query string (an alias for ``update_query()`` method).
`#435 <https://github.com/aio-libs/yarl/issues/435>`_
- Allow use of sequences such as ``list`` and ``tuple`` in the values
of a mapping such as ``dict`` to represent that a key has many values::
url = URL("http://example.com")
assert url.with_query({"a": [1, 2]}) == URL("http://example.com/?a=1&a=2")
`#443 <https://github.com/aio-libs/yarl/issues/443>`_
- Support URL.build() with scheme and path (creates a relative URL).
`#464 <https://github.com/aio-libs/yarl/issues/464>`_
- Cache slow IDNA encode/decode calls.
`#476 <https://github.com/aio-libs/yarl/issues/476>`_
- Add ``@final`` / ``Final`` type hints
`#477 <https://github.com/aio-libs/yarl/issues/477>`_
- Support URL authority/raw_authority properties and authority argument of ``URL.build()`` method.
`#478 <https://github.com/aio-libs/yarl/issues/478>`_
- Hide the library implementation details, make the exposed public list very clean.
`#483 <https://github.com/aio-libs/yarl/issues/483>`_
Bugfixes
--------
- Fix tests with newer Python (3.7.6, 3.8.1 and 3.9.0+).
`#409 <https://github.com/aio-libs/yarl/issues/409>`_
- Fix a bug where query component, passed in a form of mapping or sequence, is unquoted in unexpected way.
`#426 <https://github.com/aio-libs/yarl/issues/426>`_
- Hide `Query` and `QueryVariable` type aliases in `__init__.pyi`, now they are prefixed with underscore.
`#431 <https://github.com/aio-libs/yarl/issues/431>`_
- Keep ipv6 brackets after updating port/user/password.
`#451 <https://github.com/aio-libs/yarl/issues/451>`_
