Hyperlink provides a pure-Python implementation of immutable
URLs. Based on [RFC 3986][rfc3986] and [3987][rfc3987], the Hyperlink URL
makes working with both URIs and IRIs easy.

Hyperlink is tested against Python 2.7, 3.4, 3.5, 3.6, 3.7, 3.8, and PyPy.

Full documentation is available on [Read the Docs][docs].

## Installation

Hyperlink is a pure-Python package and requires nothing but
Python. The easiest way to install is with pip:

```
pip install hyperlink
```

Then, hyperlink away!

```python
from hyperlink import URL

url = URL.from_text(u'http://github.com/python-hyper/hyperlink?utm_source=README')
utm_source = url.get(u'utm_source')
better_url = url.replace(scheme=u'https', port=443)
org_url = better_url.click(u'.')
```

See the full API docs on [Read the Docs][docs].

## More information

Hyperlink would not have been possible without the help of
[Glyph Lefkowitz](https://glyph.twistedmatrix.com/) and many other
community members, especially considering that it started as an
extract from the Twisted networking library. Thanks to them,
Hyperlink's URL has been production-grade for well over a decade.
