This package provides Guile bindings to libgit2, a library to manipulate repositories of the Git version control system.

Guile-JSON supports parsing and building JSON documents according to the specification. These are the main features:

• Strictly complies to specification.

• Build JSON documents programmatically via macros.

• Unicode support for strings.

• Allows JSON pretty printing.

This package provides a GNU Guile interface to the zstd (``zstandard'') compression library.

Guile bytestructures offers a system imitating the type system of the C programming language, to be used on bytevectors. C's type system works on raw memory, and Guile works on bytevectors which are an abstraction over raw memory. It's also more powerful than the C type system, elevating types to first-class status.

Guile-bzip2 is a Guile wrapper for the libbzip2 library. It exposes an interface similar to other Guile compression libraries, like Guile-zlib.

Guile-JSON supports parsing and building JSON documents according to the specification. These are the main features:

• Strictly complies to specification.

• Build JSON documents programmatically via macros.

• Unicode support for strings.

• Allows JSON pretty printing.

GNU GV is a graphical user interface to the Ghostscript interpreter. With it, one can view and navigate through PostScript and PDF documents in X Windows.

GNU gxmessage is a program that pops up dialog windows, which display a message to the user and waits for their action. The program then exits with an exit code corresponding to the response.

Memtest86+ is a thorough, stand-alone memory test for x86 systems. It repeatedly writes different patterns to all memory locations, reads them back again, and verifies whether the result is the same as what was written. This can help debug even intermittent and non-deterministic errors.

It runs independently of any operating system, at computer boot-up, so that it can scan as much of your RAM as possible for hardware defects.

edid-decode decodes EDID monitor description data in human-readable format and checks if it conforms to the standards.

Libcpuid is a small C library to get vendor, model, branding string, code name and other information from x86 CPU. This library is not to be confused with the cpuid command line utility from package cpuid.

Liquidctl is a package with tools, drivers and a Python library to work with liquid cooling equipment such as AIO coolers, fan controllers and other devices.

The i7z utility accurately measures the current frequency and temperature of older Intel Core (i3, i5, and i7) processors including the Nehalem, Sandy Bridge, and Ivy Bridge generations. Reliable support for newer CPUs is not guaranteed, as this package has not seen significant development since 2013.

If your processor is supported, you'll get detailed reports on Turbo Boost and clock multipliers, core voltage, and time spent in different C-states. This information can be viewed in real time and/or logged to a file.

ddcutil can query and modify most external monitors' settings, such as brightness, colour levels, and input sources. Generally speaking, any setting that can be changed by pressing buttons on the monitor can be modified by ddcutil.

ddcutil communicates directly with monitors implementing the Monitor Control Command Set (MCCS). It usually does so through the the Display Data Channel Command Interface (DDC/CI) protocol on the I2C bus, but can also communicate over USB as per the USB Monitor Control Class Specification.

One particular use case is in colour profile management. Monitor calibration is relative to the monitor colour settings currently in effect, e.g. red gain. ddcutil allows colour-related settings to be saved at the time a monitor is calibrated, and restored when the calibration is applied.

This package includes udev rules that can be used by adding this package to the rules field of the udev-configuration record. It gives read/write access to i2c devices to users in the i2c group.

Brillo is a command line tool to control the brightness of backlight and LED devices on Linux.

Notable features include:

• Automatic best controller detection

• Smooth transitions and natural brightness adjustments

• Ability to save and restore brightness across boots

• Directly using sysfs to set brightness without relying on X

• Unprivileged access with no new setuid binaries

• Containment with AppArmor

This package provides a Guile Scheme API to control USB HID relay modules produced by dcttech.

Deskflow is a keyboard and mouse sharing app. Use the keyboard, mouse,or trackpad of one computer to control nearby computers, and work seamlessly between them. It's like a software KVM (but without the video). TLS encryption is enabled by default. It supports Wayland clipboard sharing.

This is a program for testing the quality of CRT/LCD screens. It displays various patterns and allows you to estimate the quality of your CRT/LCD monitor.

Wavemon is a wireless device monitor with an interactive ncurses terminal interface. It can display and plot signal and noise levels in real time. It also reports packet statistics, device configuration, network parameters, and access points and other wireless clients of your wireless network hardware.

Wavemon should work (with varying levels of detail and features) with any device supported by the Linux kernel.

ckb-next is a driver for Corsair keyboards and mice. It aims to bring the features of Corsair's proprietary software to Linux-based operating systems. It already supports much of the same functionality, including full RGB animations.

Memtester stress-tests the memory subsystem of your operating system and computer. It repeatedly writes different patterns to all memory locations, reads them back again, and verifies whether the result is the same as what was written. This can help debug even intermittent and non-deterministic errors.

Memtester runs entirely in user space. This means that you don't need to reboot to test your memory, but also that it's not possible to test all of the RAM installed in the system.

It can also be told to test memory starting at a particular physical address.

Hueplusplus is a library for controlling Philips Hue lights. Features:

• find bridges with SSDP or set an ip manually

• all common light functions (brightness, color, temperature)

• extended alert() functions, which alert in a specific color (good for notifications)

• supports sensors, rules, groups, scenes and schedules

• streaming with entertainment mode

• documented with doxygen

This package provides tools for exploring Nvidia's proprietary GPU drivers, including an assembler and a disassembler for several GPU instruction sets, and tools to deal with register databases.

OpenRGB is lighting control that doesn't depend on manufacturer software. ASUS, ASRock, Corsair, G.Skill, Gigabyte, HyperX, MSI, Razer, ThermalTake, and more supported.

Features:
