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 bindings to the GDBM key-value storage system, using Guile's foreign function interface.

This package provides Guile bindings for zlib, a lossless data-compression library. The bindings are written in pure Scheme by using Guile's foreign function interface.

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

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

Guile is the GNU Ubiquitous Intelligent Language for Extensions, the official extension language of the GNU system. It is an implementation of the Scheme language which can be easily embedded in other applications to provide a convenient means of extending the functionality of the application without requiring the source code to be rewritten.

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.

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.

This package provides user tools for the Trusted Computing Group's (TCG) TPM2 Software Stack (TSS). These programs help with common tasks such as key management, attestation, encryption, and signing.

This library offers a simple API for communicating with instruments compatible with the LXI standard that defines communication protocols for instrumentation and data acquisition systems using Ethernet. Applications can use liblxi to discover instruments on your network, send SCPI commands, and receive responses.

This is a Linux driver based on hidapi for a variety of inexpensive HID compatible USB relay modules available with different number of output relays.

The h-node project (https://www.h-node.org) aims to build a database of hardware that works with fully free operating systems. h-client is a GTK+ graphical client that is able to retrieves information on the hardware inside the computer it's running on, and on peripherals connected to it, and helps you submit that information to the h-node project along with whether the hardware works with a fully free operating system or not.

This is the Python extension to usbrelay, a Linux driver based on hidapi for a variety of inexpensive HID compatible USB relay modules. This package also includes usbrelayd.
