-# XMPP PubSub To Atom
+# Rivista XJP

-A little client that parses XMPP Pubsub Nodes and sends them as Atom Syndication Format or OPML over HTTP.
+Rivista XJP ("XMPP Journal Publisher"); previously XMPP PubSub To Atom ("XPTA").

-## About
+Rivista is a software that parses XMPP Pubsub Nodes and sends them as Atom
+Syndication Format or OPML over HTTP.

-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.
+Rivista 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)).

-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)).
+Rivista includes [XSLT ](https://www.w3.org/TR/xslt/) stylesheets that transform
+PubSub nodes into static XHTML journal sites.

-This software was inspired from Tigase and was motivated by Movim.

+## Motivation
+
+Rivista is a syndication project which makes journals and publications that are
+hosted on XMPP PubSub nodes, available from HTTP to both, XML news readers and
+even HTML browsers.
+
+This means that instead of hosting a journal or publication site in the old
+fashion (i.e. HTML documents hosted on an HTTP server), one only has to have an
+HTTP server to operate Rivista, and the rest of the content is delivered from an
+XMPP server (i.e. PubSub nodes).
+
+The project also showcases the non-necessity of HTML, as it automatically
+generates valid XHTML pages by HTML browsers (client-side) from XSLT
+stylesheets.
+
+Because Rivista reads XMPP PubSub nodes, it is possible to view a complete set
+of node items, and even a single node item, which means, that a considered and
+carefully earnest use of Rivista would save bandwidth and system overhead, which
+includes CPU, I/O and RAM usage.

 ## Requirements

 * Python >= 3.5
+* beautifulsoup4
 * fastapi
-* feedgenerator
 * lxml
+* markdown
 * slixmpp
-* tomllib
+* tomllib (Python <= 3.10)
 * uvicorn

 ## Installation

-### Download
+It is possible to install Rivista using pip and pipx.

-Extract the source package to a directory that you have permission to run
-software.
+#### pip inside venv

-```shell
-$ git clone https://git.xmpp-it.net/sch/PubSubToAtom
-$ cd PubSubToAtom/
+```
+$ python3 -m venv .venv
+$ source .venv/bin/activate
 ```

-### Configure
+##### Install

-Add account credentials to file `configuration.toml`.
+```
+$ pip install git+https://git.xmpp-it.net/sch/Rivista
+```
+
+#### pipx
+
+##### Install
+
+```
+$ pipx install git+https://git.xmpp-it.net/sch/Rivista
+```
+
+##### Update
+
+```
+$ pipx uninstall rivista
+$ pipx install git+https://git.xmpp-it.net/sch/Rivista
+```

 ### Start

-Execute PubSubToAtom with one of the following commands:
-
-```shell
-$ python -m uvicorn pubsub_to_atom:app --reload
-$ python -m uvicorn pubsub_to_atom:app --reload --host 127.0.0.1 --port 8000
-$ uvicorn pubsub_to_atom:app --host 127.0.0.1 --port 8000
-$ fastapi dev pubsub_to_atom.py
 ```
+$ rivista
+```
+
+Open URL http://localhost:8000

 ## Usage

-It is 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.

+  NOTE
+
+  The reason for the following code to parse HTML inside an software which
+  already parses HTML, is that some people who influence the so called Gecko
+  HTML Engine product (mostly people from the advertisement industry with whom
+  I shamefully used to work with) have intentions to eliminate standards and
+  technologies such as Syndication (Atom/RDF/RSS), XSLT and many other
+  technologies that actually empower people and their privacy.
+
+  Recently, some changes were made to the XSLT parser of Gecko which result in
+  noncompliance with the XSLT standard.
+
+  The XSLT feature that was removed is "disable-output-escaping" which upon the
+  value "yes" the XSLT engine should transform and treat a subject string into
+  HTML, yet the Gecko HTML Engine ignores this XSLT direction.
+
+  This change was probably made in order to:
+  * Frustrate new XSLT developers; or
+  * Influence new XSLT developers to think that XSLT has a limited set of
+    features and believing of some sort of inability to parse HTML from a
+    retrieved HTML string; and
+  * Consequently cause developers to abstain from using the XSLT technology.
+
+  Do not use HTML browsers or use Ladybird, Pale Moon or browsers that are
+  powered by KHTML (WebKit) instead of anti-privacy software such as Chromium
+  and Gecko.
