|
||||
|
||||
## About
|
||||
|
||||
XMPP PubSub To Atom ("XPTA") is a simple Python script that parses XMPP Pubsub Nodes and sends them as Atom Syndication Format or OPML over HTTP.
|
||||
|
||||
XPTA generates Atom syndication feeds ([RFC 4287](https://www.rfc-editor.org/rfc/rfc4287)) from XMPP PubSub nodes ([XEP-0060](http://xmpp.org/extensions/xep-0060.html)).
|
||||
|
||||
This software was inspired from Tigase and was motivated by Movim.
|
||||
|
||||
## Requirements
|
||||
|
||||
* Python >= 3.5
|
||||
* fastapi
|
||||
* feedgenerator
|
||||
* lxml
|
||||
* slixmpp
|
||||
* tomllib
|
||||
|
||||
## Installation
|
||||
|
||||
Extract the source package to a directory that you have permission to run
|
||||
software.
|
||||
|
||||
Execute with one of the followings:
|
||||
|
||||
```shell
|
||||
$ uvicorn pubsub_to_atom:app --host 127.0.0.1 --port 8000
|
||||
$ python -m uvicorn pubsub_to_atom:app --reload
|
||||
$ fastapi dev pubsub_to_atom.py
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
It ois possible to view a complete node and even a single item, which means, that it is possible to save bandwidth and it further means that a considered and carefully earnest use of this software would saves system overhead, which includes CPU, I/O and RAM usage.

||||
