guile-tap is a library for GNU Guile that implements a framework for specifying test cases that emit output that adheres to the Test Anything Protocol (TAP). It comes with an experimental harness (tap-harness).

Gulie-CoAP is a Guile implementation of the Constrained Application Protocol (CoAP). CoAP is a network transport protocol specialized for use with constrained nodes and constrained networks (e.g. low-power, lousy). This library implements basic serialization of CoAP messages over UDP (RFC 7252) and TCP (RFC 8323) as well as an asynchronous TCP client (using guile-fibers).

Guile Knots is a collection of patterns and functionality that is useful when using Guile Fibers. This includes higher level concurrency utilities, support for timeouts and a web server.

MiniKanren is a relational programming extension to the Scheme programming Language, written as a smaller version of Kanren suitable for pedagogical purposes. It is featured in the book, The Reasoned Schemer, written by Dan Friedman, William Byrd, and Oleg Kiselyov.

This is Ian Price's r6rs packaged version of miniKanren, which deviates slightly from miniKanren mainline.

See http://minikanren.org/ for more on miniKanren generally.

Guile-CV is a Computer Vision functional programming library for the Guile Scheme language. It is based on Vigra (Vision with Generic Algorithms), a C++ image processing and analysis library. Guile-CV contains bindings to Vigra C (a C wrapper to most of the Vigra functionality) and is enriched with pure Guile Scheme algorithms, all accessible through a nice, clean and easy to use high level API.

This package provides macros for functional chaining in Guile, similar to UNIX pipes (|), Clojure's threading macros (-> and ->>).

guile-avatar helps you to determine avatars (or profile pictures) for email addresses using the Libravatar specification.

This package provides a Guile programming interface to the ZeroMQ messaging library.

The (hashing …) modules implement cryptographic hash functions in pure R6RS Scheme: CRC, HMAC, MD5, SHA-1, and SHA-2 (SHA-256, SHA-512).

This package provides a Guile 2.x kernel for the Jupyter Notebook. It allows users to interact with the Guile REPL through Jupyter.

AC/D-Bus is an implementation of the D-Bus wire protocol. D-Bus is an interprocess communication protocol popular on GNU/Linux systems to communicate with a variety of services. Originally designed for desktop environments, it is now used by programs like VLC media player, BlueZ, NetworkManager, Pulseaudio, systemd (including logind and resolved), Polkit, gnome-keyring, and many more.

Guile OpenAI is an implementation of the OpenAI API in Guile Scheme, providing a convenient interface for interactive programming with their AI models.

Lokke intends to provide a full dialect of Clojure for Guile. It also consists of a set of Guile modules providing some of Clojure's functionality in two different guises.

This package provides a Guile library to parse command line arguments into structured objects. It allows declaring arguments through a small DSL, then call a procedure to parse the command line into a structured object.

guile-ini is a GNU Guile library for working with the INI format. This library provides API for reading and writing INI data.

Guile port of racket-algorithms, a package containing useful algorithms borrowed from other programming languages).

Guile-redis provides a Scheme interface to the Redis key-value cache and store.

This package contains helper functions for working with file system locations.

This package provides a Guile library to communicate with a Debbugs bug tracker's SOAP service, such as https://bugs.gnu.org.

This tiny package provides some procedures and macros to extend Guile Scheme procedure composition facilities. For example, there is a compose-top, a reverse-order analog to native compose procedure. The compose-cont is a macro, utilizing some power of continuations to build really flexible flows.

This library is intended to stay basic and small, so it has no any external dependencies and can be a good base for other packages, like e.g. guile-web-middleware.

Guile-ERIS is a Guile implementation of the Encoding for Robust Immutable Storage (ERIS). ERIS allows arbitrary content to be encoded into uniformly sized, encrypted blocks that can be reassembled using a short read-capability.

Guildhall is a package manager written for Guile Scheme. A guild is an association of independent craftspeople. A guildhall is where they meet. This Guildhall aims to make a virtual space for Guile wizards and journeyfolk to share code.

On a practical level, Guildhall lets you share Scheme modules and programs over the internet, and install code that has been shared by others. Guildhall can handle dependencies, so when a program requires several libraries, and each of those has further dependencies, all of the prerequisites for the program can be installed in one go.

Guile-Forgejo provides an interface to the Forgejo HTTP interface so you can talk to Forgejo instances such as Codeberg from the comfort of Scheme.

guile-dbi is a library for Guile that provides a convenient interface to SQL databases. This package implements the interface for MySQL.
