plugin XEP-0447: handle attachment and download: - plugin XEP-0447 can now be used in message attachments and to retrieve an attachment - plugin attach: `attachment` being processed is added to `extra` so the handler can inspect it - plugin attach: `size` is added to attachment - plugin download: a whole attachment dict is now used in `download` and `file_download`/`file_download_complete`. `download_uri` can be used as a shortcut when just a URI is used. In addition to URI scheme handler, whole attachment handlers can now be registered with `register_download_handler` - plugin XEP-0363: `file_http_upload` `XEP-0363_upload_size` triggers have been renamed to `XEP-0363_upload_pre_slot` and is now using a dict with arguments, allowing for the size but also the filename to be modified, which is necessary for encryption (filename may be hidden from URL this way). - plugin XEP-0446: fix wrong element name - plugin XEP-0447: source handler can now be registered (`url-data` is registered by default) - plugin XEP-0447: source parsing has been put in a separated `parse_sources_elt` method, as it may be useful to do it independently (notably with XEP-0448) - plugin XEP-0447: parse received message and complete attachments when suitable - plugin XEP-0447: can now be used with message attachments - plugin XEP-0447: can now be used with attachments download - renamed `options` arguments to `extra` for consistency - some style change (progressive move from legacy camelCase to PEP8 snake_case) - some typing rel 379

================================
uri: XMPP URI parsing/generation
================================

URI commands are helper to easily parse/build XMPP URIs.

parse
=====

Parse an XMPP URI, and print different parts.

When possible, the ``type`` of URI is shown (e.g. ``pubsub``) and the ``sub_type`` (e.g.
``microblog``).

The ``path`` is always displayed (see `RFC 5122 Path section`_ for details).

If suitable, you'll also get data like ``node`` (for a PubSub URI).

.. _RFC 5122 Path section: https://tools.ietf.org/html/rfc5122#section-2.4

examples
--------

Parse a blog URI::

  $ li uri parse "xmpp:somebody@example.org?;node=urn%3Axmpp%3Amicroblog%3A0"

build
======

Build an XMPP URI according to arguments. 2 positional arguments are expected: ``type``
and ``path``. For now, only ``pubsub`` type is supported.

examples
--------

Build XMPP URI for a blog::

  $ li uri build pubsub somebody@example.org -f node urn:xmpp:microblog:0
