squee is a Guile library for connecting to PostgreSQL databases using Guile's foreign function interface.

guile-aspell is a Guile Scheme library for comparing a string against a dictionary and suggesting spelling corrections.

This package provides Guile bindings for the taglib C library. It can be used to access and modify metadata for audio files.

Guile-syntax-highlight is a general-purpose syntax highlighting library for GNU Guile. It can parse code written in various programming languages into a simple s-expression that can be converted to HTML (via SXML) or any other format for rendering.

This package provides facilities for working with .torrent or metainfo files. Implements a bencode reader and writer according to Bitorrent BEP003.

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

This package provides a Guile library for Internet Relay Chat (IRC).

This package provides tooling to write web applications in Guile, such as signed sessions, multipart message support, etc.

Haunt is a static site generator written in Guile Scheme. Haunt features a functional build system and an extensible interface for reading articles in any format.

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

Guile-Quickcheck is a library for random testing of program properties inspired by ghc-quickcheck. You can use it to express properties, which functions should satisfy, as Scheme code and then check whether they hold in a large number of randomly generated test cases.

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

guile-filesystem provides a set of utility functions, that augment Guile's support for handling files and their names.

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

guile-sjson is a json reader/writer for Guile. It has a nice, simple s-expression based syntax.

This Guile library provides tools for reading, comparing, and writing Semantic Versions. It also includes ranges in the style of the Node Package Manager (NPM).

guile-goblins is the Guile version of Spritely Goblins, a transactional, distributed programming environment following object capability security designs. Goblins is a general toolkit, and also the core layer of Spritely's work to support healthy distributed networked communities. Goblins allows for cooperation between networked programs in a mutually suspicious network through OCapN, the Object Capability Network. This includes collaboration across runtimes; for instance, programs written in the Guile and Racket versions of Goblins are able to speak to each other.

Fibers is a Guile library that implements a a lightweight concurrency facility, inspired by systems like Concurrent ML, Go, and Erlang. A fiber is like a "goroutine" from the Go language: a lightweight thread-like abstraction. Systems built with Fibers can scale up to millions of concurrent fibers, tens of thousands of concurrent socket connections, and many parallel cores. The Fibers library also provides Concurrent ML-like channels for communication between fibers.

Note that Fibers makes use of some Guile 2.1/2.2-specific features and is not available for Guile 2.0.

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

Guile-Lens is a library implementing lenses in Guile. The library is currently a re-implementation of the lentes library for Clojure. Lenses provide composable procedures, which can be used to focus, apply functions over, or update a value in arbitrary data structures.

This package provides a complete Scheme implementation of miniAdapton, which implements the core functionality of the Adapton system for incremental computation (also known as self-adjusting computation). Like Adapton, miniAdapton allows programmers to safely combine mutation and memoization. miniAdapton is built on top of an even simpler system, microAdapton. Both miniAdapton and microAdapton are designed to be easy to understand, extend, and port to host languages other than Scheme.

This library provides a reference implementation for SRFI-197. This SRFI defines a family of chain and nest pipeline operators, which can rewrite nested expressions like (a b (c d (e f g))) as a sequence of operations: (chain g (e f _) (c d _) (a b _)).

Guile-colorized provides you with a colorized REPL for GNU Guile.

GuileScript is a toy compiler that aims to compile Guile to JavaScript. It currently does not do much, but it might in the future.
