Introduction
------------
Url is constructed from ``str``::
>>> 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::
>>> 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 produces a new url object::
>>> url.parent / 'downloads/source'
URL('https://www.python.org/downloads/source')
Strings passed to constructor and modification methods are
automatically encoded giving canonical representation as result::
>>> 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::
>>> url.path
'/путь'
>>> url.raw_path
'/%D0%BF%D1%83%D1%82%D1%8C'
Human readable representation of URL is available as ``.human_repr()``::
>>> url.human_repr()
'https://www.python.org/путь'

Installation
------------
::
$ pip install yarl
The library is Python 3 only!
Dependencies
------------
YARL requires multidict_ library.
API documentation
------------------
The documentation is located at https://yarl.readthedocs.org
Comparison with other URL libraries
------------------------------------
* furl (https://pypi.python.org/pypi/furl)
The library has a rich functionality but ``furl`` object is mutable.
I 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 any decode/encode transformations leaving end
user to cope with these gory details.
Source code
-----------
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 `Travis <https://travis-ci.org/aio-libs/yarl>`_ for
Continuous Integration.
