Releases have happened recently that revolve around Poezio, a TUI (Terminal UI) client for XMPP, including Poezio itself, its backend XMPP library Slixmpp, and also the poezio and slixmpp plugins for OMEMO.
Many bug fixes and improvements
Mathieui has already made a proper release note for Slixmpp and I invite you to read it! It includes many bugfixes of course, and internal changes around async handling, that may reflect on some of the APIs you are using.
Poezio has also seen many improvements.
Internally, for one, our default branch has also been moved to “main”, many type hints have been added, implicit casts (safeJID) have been removed, lots of event handlers and calls are now async, APIs from Slixmpp are being used instead of redoing our own, many refactoring, various performance improvements.
Pypy3 support was removed because it was causing many users to use the cffi
module specifically implemented for pypy3 instead of the more performant C
implementation. For those who are running from sources and not using the
update script, don’t forget to run
make to build the C module.
A license change has happened, and Poezio is now under GPLv3+! While I am not exactly in favour of intellectual property1, this is a straightforward lever we have against capitalism2. Poezio being a prime resource for Slixmpp examples, GPL code should reasonably ensure that the 4 freedoms reach end-users. In practice, this should allow for poezio-omemo to be merged into Poezio. I am now personally hoping for Slixmpp to change its license as well.
And other changes more visible to users! To name a few, quality of life
improvements such as
xmpp:...?join URIs handling in
/join, impromptu rooms
creation is now more reliable and creates rooms with shorter names, and tab
names in the activity bar can be colored using Consistent Color
Generation by setting
True. Read more in the changelog.
Plugins have seen changes as well. A new
untrackme plugin replaces the now
remove_get_trackers. Link Mauve has also developed
sticker plugin (to send them), similar in essence to what Movim
has been doing for ages. Rich presence (activity, gaming, mood and user tune)
has been removed from Poezio core and moved in the
user_extras plugin. And
again many fixes.
Many of these fixes have been realized by mathieui, who is by far the biggest committer on the release, and in general probably the person with the best understanding of the project. Thanks also to louiz for providing the infrastructure all this time, and to eijebong, Ge0rG, Kaghav Gururajan, kaliko, Thomas Hrnciar, jonas’, and southerntofu for the many patches.
Archive handling (MAM) was already in the previous release, but has been reworked and should now be more reliable.
When opening a tab, Poezio will fetch 2 screen pages worth of messages if it has no logs for this tab. Archives are automatically stored locally if configured (default), in which case they won’t be re-downloaded but read from the local copy directly the next time they’re requested.
To read older chat messages in a tab, just scroll up with
PageUp and Poezio
will fetch more automatically if it needs to.
This is configurable with options that have been introduced such as
mam_sync_limit to enable/disable
the use of MAM and how many messages to fetch at most. And
use_log also configures the fact that archives are stored
Some work around storing message IDs – that our log format doesn’t do – will be needed in the future to allow for easier message deduplication.
E2EEPlugin API has been improved to accommodate changes in
poezio-omemo, slixmpp-omemo and changes of the OMEMO backend library. Two
plugins which are also seeing changes!
Heartbeats are now supported. Heartbeats are meta-messages which transfer only cryptographic key material (nothing else) and are used to strengthen OMEMO’s forward secrecy. This is particularly relevant on clients like Poezio that can stay running in the back for some time, receiving messages without replying.
What hasn’t changed is that this plugin lacks a UI and trust management. Hopefully this should come soon, with a little motivation to do UI work.
What comes next
All in all, there aren’t (m)any revolutionary changes, but with these releases come many fixes for paper cuts that hopefully make users happier. This makes me think that even though Poezio is far from being perfect, there doesn’t seem to be many important things missing.
There are however changes that would require a lot of refactoring, such as a multi-account feature, or easier maintenance in general.
We have decided to start migrating Poezio to Rust, in part to be able to refactor the project more easily, and also because it’s a language we’ve come to appreciate over the years with experience in other projects, and more specifically with xmpp-rs, an XMPP library in Rust.
All of this will happen right after the release, and we invite interested people to join the effort!
P.S.: I am looking for poezio screenshots with various setups to display in
public places, under a free license. Please send me your screenshots in
relatively high quality at
bouah.net. And don’t forget to ask
pixels appearing on the image for permission!
