QtSpell adds spell-checking functionality to Qt's text widgets, using the Enchant spell-checking library.

SIP is a tool to create Python bindings for C and C++ libraries. It was originally developed to create PyQt, the Python bindings for the Qt toolkit, but can be used to create bindings for any C or C++ library.

SIP comprises a code generator and a Python module. The code generator processes a set of specification files and generates C or C++ code, which is then compiled to create the bindings extension module. The SIP Python module provides support functions to the automatically generated code.

This package provides an abstraction layer on top of the various Qt bindings (PySide, PySide2, PyQt4 and PyQt5).

The QtScript module provides classes for making Qt applications scriptable. This module provides a set of extra components that can be used to build complete interfaces in Qt Quick.

Quil is the quantum instruction language, originally developed at Rigetti Computing. In Quil quantum algorithms are expressed using Quil's standard gates and instructions

This is the official Quil-Lang Quantum Virtual Machine (QVM), a flexible and efficient simulator for Quil.

This package provides the asynchronous RPC client-server framework and message specification for Rigetti Quantum Cloud Services (QCS). It implements an efficient transport protocol by using ZeroMQ (ZMQ) sockets and MessagePack (msgpack) serialization.

This variant of the Racket BC (``before Chez'' or ``bytecode'') implementation is not recommended for general use. It uses CGC (a ``Conservative Garbage Collector''), which was succeeded as default in PLT Scheme version 370 (which translates to 3.7 in the current versioning scheme) by the 3M variant, which in turn was succeeded in version 8.0 by the Racket CS implementation.

Racket CGC is primarily used for bootstrapping Racket BC [3M]. It may also be used for embedding applications without the annotations needed in C code to use the 3M garbage collector.

The Racket CS implementation, which uses ``Chez Scheme'' as its core compiler and runtime system, has been the default Racket VM implementation since Racket 8.0. It performs better than the Racket BC implementation for most programs. On systems for which Racket CS cannot generate machine code, this package uses a variant of its ``portable bytecode'' backend specialized for word size and endianness.

Using the Racket VM packages directly is not recommended: instead, install the racket-minimal or racket packages.

Racket is a general-purpose programming language in the Scheme family, with a large set of libraries and a compiler based on Chez Scheme. Racket is also a platform for language-oriented programming, from small domain-specific languages to complete language implementations.

The main Racket distribution comes with many bundled packages, including the DrRacket IDE, libraries for GUI and web programming, and implementations of languages such as Typed Racket, R5RS and R6RS Scheme, Algol 60, and Datalog.

Zuo is a tiny Racket with primitives for dealing with files and running processes. It comes with a make-like embedded DSL, which is used to build Racket itself.

Zuo is a Racket variant in the sense that program files start with #lang, and the module path after #lang determines the parsing and expansion of the file content. That's how the make-like DSL is defined, and even the base Zuo language is defined by layers of #langs. One of the early layers implements macros.

Racket is a general-purpose programming language in the Scheme family, with a large set of libraries and a compiler based on Chez Scheme. Racket is also a platform for language-oriented programming, from small domain-specific languages to complete language implementations.

The ``minimal Racket'' distribution includes just enough of Racket for you to use raco pkg to install more. Bundled packages, such as the DrRacket IDE, are not included.

The Racket BC (``before Chez'' or ``bytecode'') implementation was the default before Racket 8.0. It uses a compiler written in C targeting architecture-independent bytecode, plus a JIT compiler on most platforms. Racket BC has a different C API than the current default runtime system, Racket CS (based on ``Chez Scheme'').

This package is the normal implementation of Racket BC with a precise garbage collector, 3M (``Moving Memory Manager'').

The Ham Radio Control Library (Hamlib) is a project to provide programs with a consistent Application Programming Interface (API) for controlling the myriad of radios and rotators available to amateur radio and communications users.

Command line utilities and a C library for controlling the HackRF Software Defined Radio (SDR) over USB. Installing this package installs the userspace hackrf utilities and C library. To install the hackrf udev rules, you must extend 'udev-service-type' with this package. E.g.: (udev-rules-service 'hackrf hackrf #:groups '("dialout")).

This package provides RTL-SDR devices support to the SoapySDR library.

Minimodem is a command-line program which decodes (or generates) audio modem tones at any specified baud rate, using various framing protocols. It acts a general-purpose software FSK modem, and includes support for various standard FSK protocols such as Bell103, Bell202, RTTY, TTY/TDD, NOAA SAME, and Caller-ID.

This package provides a set of functions that implement several popular forward error correction (FEC) algorithms and several low-level routines useful in modems implemented with digital signal processing (DSP).

This is a SoapySDR module to use a supported device transparently over a local network link.

The Universal Radio Hacker (URH) is a complete suite for wireless protocol investigation with native support for many common Software Defined Radios.

redsea is a lightweight command-line FM Radio Data System (FM-RDS) decoder. Redsea can be used with any RTL-SDR USB radio stick with the rtl_fm tool, or any other software-defined radio (SDR) via csdr, for example. It can also decode raw ASCII bitstream, the hex format used by RDS Spy, and audio files containing multiplex signals (MPX).
