Parse and format link headers according to RFC 5988 "Web Linking"

Project description

Parse and format link headers according to RFC 5988 “Web Linking”.

Usage (assuming a suitable headers object in the environment):

>>> headers['Link'] = str(LinkHeader([Link("http://example.com/foo", rel="self"),
...                                   Link("http://example.com", rel="up")]))
>>> headers['Link']
'<http://example.com/foo>; rel=self, <http://example.com>; rel=up'
>>> parse(headers['Link'])
LinkHeader([Link('http://example.com/foo', rel='self'), Link('http://example.com', rel='up')])

Blank and missing values roundtrip correctly:

>>> format_link(parse('</s/1>; obs; if="core.s"; foo=""'))
'<</s/1>; obs; if=core.s; foo="">'

Conversions to and from json-friendly list-based structures are also provided:

>>> parse(headers['Link']).to_py()
[['http://example.com/foo', [['rel', 'self']]], ['http://example.com', [['rel', 'up']]]]
>>> str(LinkHeader([['http://example.com/foo', [['rel', 'self']]],
...                 ['http://example.com', [['rel', 'up']]]]))
'<http://example.com/foo>; rel=self, <http://example.com>; rel=up'
