FreeForth2 offers a lightweight Forth for x86 GNU/Linux that deftly blends assembly and Forth.

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.

test-drive is a procedural unit testing framework for Fortran.

This library implements an electronegativity equilibration model to calculate partial charges used in the DFT-D4 model.

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

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

ForUtils is a modern Fortran utility library that provides essential tools for scientific computing and data processing. It offers Python-like convenience functions and object-oriented interfaces for common programming tasks in Fortran 2003/2008 programs.

Key Features:

• ArrayUtils - find (minimal/maximal) index of an element in an array

• FileUtils - classes for handling file access, python-like loadtxt/savetxt functions

• IniObjects - read/write name=value configuration files with inheritance, array and default value support

• MatrixUtils - read/write matrices and interface to some BLAS/LAPACK routines

• MiscUtils - utility functions for optional arguments

• MpiUtils - wrappers for MPI-routines to compile with(out) MPI library

• ObjectLists - lists of arbitrary objects including specializations for vectors

• RandUtils - some functions to generate random numbers

• RangeUtils - maintain sets of equally spaced intervals, e.g. for integration ranges

• StringUtils - utilities for strings, like concat of distinct types a.s.o.

This library provides an implementation of TOML data serialization and deserialization in Fortran.

mctc-lib (modular computation tool chain library) is a Fortran library for operating on molecular structures and reading and writing common geometry file formats.

This library provides an implementation of the https://www.chemie.uni-bonn.de/grimme/de/software/dft-d3/ dispersion correction.

This package contains a number of commandline utilities for use inside Flatpak sandboxes and other containers, like guix shell --container. They work by talking to portals. Currently, there is flatpak-spawn for running commands in sandboxes as well as xdg-open and xdg-email, which are compatible with the well-known scripts of the same name.

Libglib-testing is a test library providing test harnesses and mock classes which complement the classes provided by GLib. It is intended to be used by any project which uses GLib and which wants to write internal unit tests.

Libmbim is a GLib-based library for talking to WWAN modems and devices which speak the Mobile Interface Broadband Model (MBIM) protocol.

File::Mimeinfo can be used to determine the MIME type of a file. It tries to implement the Freedesktop specification for a shared MIME database.

This package also contains two related utilities:

• mimetype determines a file's MIME type;

• mimeopen opens files in an appropriate program according to their MIME type.

Exempi is an implementation of the Extensible Metadata Platform (XMP), which enables embedding metadata in PDF and image formats.

Idle is an IRC connection manager for the Telepathy framework. This package enables usage of IRC channels and private messages in Telepathy instant messaging clients such as Empathy, GNOME Shell or KDE Telepathy.

Elogind is the systemd project's "logind" service, extracted out as a separate project. Elogind integrates with PAM to provide the org.freedesktop.login1 interface over the system bus, allowing other parts of a the system to know what users are logged in, and where.

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.

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.

fprintd is a D-Bus daemon that offers functionality of libfprint, a library to access fingerprint readers, over the D-Bus interprocess communication bus. This daemon layer above libfprint solves problems related to applications simultaneously competing for fingerprint readers.

iio-sensor-proxy is a daemon which passes IIO sensor data to D-Bus.

This library supports a subset of the ATA S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology) functionality.

libqrtr-glib is a glib-based library to use and manage the QRTR (Qualcomm IPC Router) bus.

power-profiles-daemon offers to modify system behaviour based upon user-selected power profiles. There are 3 different power profiles, a "balanced" default mode, a "power-saver" mode, as well as a "performance" mode. The first 2 of those are available on every system. The "performance" mode is only available on select systems and is implemented by different "drivers" based on the system or systems it targets. In addition to those 2 or 3 modes (depending on the system), "actions" can be hooked up to change the behaviour of a particular device. For example, this can be used to disable the fast-charging for some USB devices when in power-saver mode.
