This package provides a library of procedures for formatting Scheme objects to text in various ways, and for easily concatenating, composing and extending these formatters efficiently without resorting to capturing and manipulating intermediate strings.

Chez Scheme is both a programming language and a high-performance implementation of that language. The language is a superset of R6RS Scheme with numerous extensions, including native threads, non-blocking I/O, local modules, and much more. Chez Scheme compiles source expressions incrementally to machine code, providing the speed of compiled code in an interactive system. The system is intended to be as reliable and efficient as possible, with reliability taking precedence over efficiency if necessary.

This package provides a port of the MIT/GNU Scheme Scmutils program to Chez Scheme. The port consists of a set of libraries providing most of the functionality of the original.

This package provides a collection of SRFI libraries for Chez Scheme.

Schemesh is an interactive shell scriptable in Lisp. It supports interactive line editing, autocompletion, history and the familiar Unix shell syntax.

The Nanopass framework is an embedded domain-specific language for writing compilers composed of several simple passes that operate over well-defined intermediate languages. The goal of this organization is both to simplify the understanding of each pass, because it is responsible for a single task, and to simplify the addition of new passes anywhere in the compiler. Nanopass reduces the boilerplate required to create compilers, making them easier to understand and maintain.

ChezWEB is a system for doing Knuthian style WEB programming in Scheme.

The threads implemented in CHICKEN are so called "green" threads, based on first-class continuations. Native threads that map directly to the threads provided by the operating system are not supported. The advantage of this is that threads are very lightweight and somewhat larger degree of determinism. The disadvantage is that execution of Scheme code on multiple processor cores is not available.

The crypto-tools egg implements useful cryptographic primitives. More specifically, provided are:

• binary blobs

  • marshallers to and from hex strings

  • blob xor

  • blob padding using either PKCS#5 or ISO7816-4

• Block cipher modes of operation

  • CBC with or without incorporated encrypted IV in the ciphertext

  • CTR with or without incorporated IV in the ciphertext

This egg provides a way to do on-the-fly compilation of source code and load it into the running process.

This package provides an implementation of SRFI-69 hash tables for CHICKEN Scheme, along with SRFI-90 extensions.

CHICKEN is a compiler for the Scheme programming language. CHICKEN produces portable and efficient C, supports almost all of the R5RS Scheme language standard, and includes many enhancements and extensions.

This package provides the SRFI-13 string library for Chicken scheme.

This ``integer set'' CHICKEN Scheme library implements bit vectors. Bit-vectors provide an abstract interface to bitwise operations typically done with integers.

This package provides a simple testing utility for CHICKEN Scheme.

The list library defined in SRFI-1 contains a lot of useful list processing procedures for construction, examining, destructuring and manipulating lists and pairs.

Character sets can be created, extended, tested for the membership of a characters and be compared to other character sets

This CHICKEN Scheme library provides a facility for creating and using variant records, as described in the book Essentials of Programming Languages by Friedman, Wand, and Haynes.

This library implements the Wu-Manber algorithm for approximate string searching with errors, popularized by the agrep Unix command and the glimpse file indexing tool.

Ungoogled-Chromium is the Chromium web browser, with some functionality disabled in order to protect the users privacy. This package also includes the chromedriver command, which can be useful for automated web testing.

Forgejo Runner is a daemon that connects to a Forgejo instance and runs jobs for continuous integration.

Cuirass is a continuous integration tool using GNU Guix. It is intended as a replacement for Hydra.

Laminar is a lightweight and modular continuous integration service. It doesn't have a configuration web UI instead uses version-controllable configuration files and scripts.

Laminar encourages the use of existing tools such as bash and cron instead of reinventing them.
