T1lib is a library for generating/rasterising bitmaps from Type 1 fonts. It is based on the code of the X11 rasteriser of the X11 project.

The bitmaps created by t1lib are returned in a data structure with type GLYPH. This special GLYPH-type is also used in the X11 window system to describe character bitmaps. It contains the bitmap data as well as some metric information. But t1lib is in itself entirely independent of the X11-system or any other graphical user interface.

Gforth is a fast and portable implementation of the ANSI Forth language. It includes an editing mode for Emacs and an interpreter featuring completion and history. A generic virtual machine environment, vmgen, is also included.

This library provides an implementation of the DFT-D4 dispersion correction with both a Fortran and a C interface.

This package contains a Fortran interface to obtain molecular geometries used for testing.

Some projects rely on the sd-bus library for DBus support. However not all systems have systemd or elogind installed. This library provides just sd-bus (and the busctl utility).

This is a GTK convenience library for interacting with colord. It is useful for both applications which need colour management and applications that wish to perform colour calibration.

Telepathy logger is a headless observer client that logs information received by the Telepathy framework. It features pluggable backends to log different sorts of messages in different formats.

UDisks provides interfaces to enumerate and perform operations on disks and storage devices. Any application (including unprivileged ones) can access the udisksd(8) daemon via the name org.freedesktop.UDisks2 on the system message bus.

cChardet is a character encoding detector, written in Python, that binds to the C library uchardet to increase performance.

Salut is a link-local XMPP (XEP-0174) connection manager for the Telepathy framework, currently supporting presence and single-user chats with iChat interoperability, and multi-user chats and Tubes using the Clique protocol.

xdg-user-dirs is a tool to help manage "well known" user directories, such as the desktop folder or the music folder. It also handles localization (i.e. translation) of the file names. Designed to be automatically run when a user logs in, xdg-user-dirs can also be run manually by a user.

This package provides xdg-desktop-portal-wlr. This project seeks to add support for the screenshot, screencast, and possibly remote-desktop xdg-desktop-portal interfaces for wlroots based compositors.

This package provides C++ bindings for the Wayland display protocol.

This package contains a few command line utilities for working with desktop entries:

desktop-file-validate

Validates a desktop file and prints warnings/errors about desktop entry specification violations.

desktop-file-install

Installs a desktop file to the applications directory, optionally munging it a bit in transit.

update-desktop-database

Updates the database containing a cache of MIME types handled by desktop files.

This package provides Wayland protocol extensions for Hyprland.

AppStream is a cross-distribution effort for enhancing the way we interact with the software repositories provided by distributions by standardizing software component metadata. It provides the foundation to build software-center applications, by providing metadata necessary for an application-centric view on package repositories. It additionally provides specifications for things like an unified software metadata database, screenshot services and various other things needed to create user-friendly application-centers for distributions.

A library to allow applications to export a menu, originally into the Unity menu bar. Based on KSNI, it also works in KDE and will fallback to generic Systray support if none of those are available.
