This package provides GNUHealth Personal Health Record application for desktop and mobile devices that integrates with the GNU Health Federation.

Orthanc is a standalone DICOM server with a RESTful API and plugin mechanism for extending its functionality.

This package provides plugins to use MySQL or MariaDB as the database backend of an Orthanc DICOM server instead of SQLite.

This package provides plugins to use PostgreSQL as the database backend of an Orthanc DICOM server instead of SQLite.

(X)MedCon can be used to convert between different file formats used in medical imaging. The supported formats are ACR-NEMA 2.0, Analyze (SPM), Concorde/μPET, DICOM 3.0, CTI ECAT 6/7, NIfTI-1, Interfile 3.3, PNG, and GIF87a/89a. This package includes a command-line utility (medcon) and a GTK+ based GUI application (xmedcon).

Mercury is a logic/functional programming language which combines the clarity and expressiveness of declarative programming with advanced static analysis and error detection features. Its highly optimized execution algorithm delivers efficiency far in excess of existing logic programming systems, and close to conventional programming systems. Mercury addresses the problems of large-scale program development, allowing modularity, separate compilation, and numerous optimization/time trade-offs.

NYACC is set of Guile modules for generating parsers and lexical analyzers. It provides sample parsers, pretty-printers using SXML trees as an intermediate representation, a decent C parser and an `FFI Helper' tool to help create Guile Scheme bindings for C-based libraries. It also provides (partially implemented) compilers based on these parsers to allow execution with Guile as extension languages.

M2-Planet, the PLAtform NEutral Transpiler, when combined with mescc-tools, compiles a subset of the C language into working binaries with introspective steps in between. It is self-hosting and for bootstrapping it also has an implementation in the M1 macro assembly language. M2-Planet is built as Phase-5 of the full source bootstrapping process and is capable of building GNU Mes.

GNU Mes--Maxwell Equations of Software--brings the Reduced Binary Seed bootstrap to Guix and aims to help create full source bootstrapping for GNU/Linux distributions. It consists of a mutual self-hosting Scheme interpreter in C and a Nyacc-based C compiler in Scheme and is compatible with Guile.

Mescc-tools is a collection of tools for use in a full source bootstrapping process. It consists of the M1 macro assembler, the hex2 linker, the blood-elf symbol table generator, the kaem shell, exec_enable and get_machine.

Gajim aims to be an easy to use and fully-featured XMPP chat client. It is extensible via plugins, supports end-to-end encryption (OMEMO and OpenPGP) and available in 29 languages.

ZNC is an IRC network bouncer or BNC. It can detach the client from the actual IRC server, and also from selected channels. Multiple clients from different locations can connect to a single ZNC account simultaneously and therefore appear under the same nickname on IRC.

Chatty is a chat program for XMPP and SMS. It works on mobile as well as on desktop platforms. It's based on libpurple and ModemManager.

This package provides python-pypresence, a Discord RPC client written in Python.

jj is a simple file-system-based Jabber client, inspired by ii IRC client. Interaction with jj is done by writing and reading files from the server directory which jj creates. It is perfect for bots and notifications.

BitlBee brings IM (instant messaging) to IRC clients, for people who have an IRC client running all the time and don't want to run an additional IM client. BitlBee currently supports XMPP/Jabber (including Google Talk), MSN Messenger, Yahoo! Messenger, AIM and ICQ, and the Twitter microblogging network (plus all other Twitter API compatible services like identi.ca and status.net).

Telegram-purple is a plugin for Libpurple, the communication library used by the Pidgin instant messaging client, that adds support for the Telegram messenger.

This package is on ``life support'' until tdlib-purple is a full replacement.

This package shows CAPTCHA without running proprietary code.

Net::PSYC with support for TCP, UDP, Event.pm, IO::Select and Gtk2 event loops. This package includes 12 applications and additional scripts: psycion (a PSYC chat client), remotor (a control console for tor router) and many more.

This module implements support for a group of push notification extensions by the Tigase team that allow a client to specify filters to be applied to push notifications. It is a custom extension to XEP-0357: Push Notifications.
