This package provides a set of MIT/GNU Scheme compatibility libraries for Chez Scheme. The main goal was to provide the functionality required to port the program Scmutils to Chez Scheme.

Chez Scheme is a self-hosting compiler: building it requires ``boot files'' containing the Scheme-implemented portions compiled for the current platform. (Chez can then cross-compile boot files for all other supported platforms.)

The Racket package cs-bootstrap (part of the main Racket Git repository) implements enough of a Chez Scheme simulation to load the Chez Scheme compiler purely from source into Racket and apply the compiler to itself, thus bootstrapping Chez Scheme. Bootstrapping takes about 10 times as long as using an existing Chez Scheme, but cs-bootstrap supports Racket 7.1 and later, including the Racket BC variant.

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.

This package provides a superset of the popular Scheme match package by Andrew Wright, written in fully portable syntax-rules and thus preserving hygiene.

This is the precise pre-release version of Chez Scheme from a specific Racket release. It is used to build Racket and to bootstrap the released version of Chez Scheme.

The stex package extends LaTeX with a handful of commands for including Scheme code (or pretty much any other kind of code, as long as you don't plan to use the Scheme-specific transcript support) in a document. It provides the programs scheme-prep and html-prep to convert stex documents to LaTeX and HTML, respectively, plus makefile templates, style files, and other resources. The stex system is used to typeset The Scheme Programming Language and the Chez Scheme User's Guix, among other documents.

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.

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.

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.

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

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

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

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 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.

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

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

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.

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.

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