plugin XEP-0033: code modernisation, improve delivery, data validation:
- Code has been rewritten using Pydantic models and `async` coroutines for data validation
and cleaner element parsing/generation.
- Delivery has been completely rewritten. It now works even if server doesn't support
multicast, and send to local multicast service first. Delivering to local multicast
service first is due to bad support of XEP-0033 in server (notably Prosody which has an
incomplete implementation), and the current impossibility to detect if a sub-domain
service handles fully multicast or only for local domains. This is a workaround to have
a good balance between backward compatilibity and use of bandwith, and to make it work
with the incoming email gateway implementation (the gateway will only deliver to
entities of its own domain).
- disco feature checking now uses `async` corountines. `host` implementation still use
Deferred return values for compatibility with legacy code.

.. _libervia-cli_pubsub_node_schema: ========================================= pubsub/node/schema: nodes schema handling ========================================= ``node schema`` is an experimental feature to associate a data form with a PubSub node, and reject items not following this form. This feature is currently only available with Libervia PubSub. Those commands can only be used by an owner of the node. set === Set the schema of a node. The raw schema is written directly as positional argument. example ------- Set the schema for tickets node using the file ``tickets_schema.xml`` from ``$HOME`` directory. Shell substition is used here to put the content of the file in the positional argument:: $ li pubsub node schema set -n org.salut-a-toi.tickets:0 -s pubsub.example.org "$(<~/test_schema.xml)" edit ==== Edit the schema of a node using your local editor (the one set in ``$EDITOR``). If you don't change anything or publish an empty schema, the edition will be cancelled. :ref:`draft_common` commands can be used. example ------- Edit the tickets node schema:: $ li pubsub node schema edit -n org.salut-a-toi.tickets:0 -s pubsub.example.org example ------- get === Retrieve schema of a node. example ------- Get schema of tickets and save it to a file named ``tickets_schema.xml`` in ``$HOME`` directory:: $ li pubsub node schema get -n org.salut-a-toi.tickets:0 -s pubsub.example.org > ~/tickets_schema.xml
