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.

This package provides the functionality to query a SPARQL endpoint. Additionally, it provides an interface to write SPARQL queries using S-expressions.

This library implements a JavaScript Object Notation (JSON) parser and printer. It also supports parsing JSON objects that may be bigger than memory with a streaming API.

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.

Guile-Udev provides GNU Guile bindings to libudev.

The Concise Binary Object Representation (CBOR), as specified by RFC 8949, is a binary data serialization format. CBOR is similar to JSON but serializes to binary which is smaller and faster to generate and parse. This package provides a Guile implementation of CBOR.

A module for GNU Guile to read and write YAML files. It works using bindings to the yaml-cpp C++ library.

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.

This package provides a functional parser combinator library that supports backtracking and a small logical framework. The idea is to build up chunks that are memoized and there is no clear scanner/parser separation, chunks can be expressions as well as simple tokens.

Guile-XOSD provides Guile bindings for libxosd, the X On Screen Display library.

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

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.

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-Reader is a simple framework for building readers for GNU Guile.

The idea is to make it easy to build procedures that extend Guile’s read procedure. Readers supporting various syntax variants can easily be written, possibly by re-using existing “token readers” of a standard Scheme readers. For example, it is used to implement Skribilo’s R5RS-derived document syntax.

Guile-Reader’s approach is similar to Common Lisp’s “read table”, but hopefully more powerful and flexible (for instance, one may instantiate as many readers as needed).

guile-dns is a DNS library written in pure Guile Scheme.

Guile Config is a library providing a declarative approach to application configuration specification. The library provides clean configuration declaration forms, and processors that take care of: configuration file creation; configuration file parsing; command-line parameter parsing using getopt-long; basic GNU command-line parameter generation (--help, --usage, --version); automatic output generation for the above command-line parameters.

Hall is a command-line application and a set of Guile libraries that allow you to quickly create and publish Guile projects. It allows you to transparently support the GNU build system, manage a project hierarchy & provides tight coupling to Guix.

This package provides an implementation of SRFI 128 for Guile. SRFI 128 defines comparators, which bundles a test type predicate, an equality predicate, an ordering predicate and a hash function into a single Scheme object. This can be used in the implementation of data structures. This package re-uses the SRFI sample implementation.

This package provides bindings for GNU Parted library, a C library allowing disk partition tables creation and manipulation. The bindings are written in pure Scheme by using Guile's foreign function interface.

This package provides SRFI-145. This provides the means to denote the invalidity of certain code paths in a Scheme program.

Kracht provides helpful and convenient functionalities that can help you develop more comfortably in your Guile Scheme project. You can see it as a batteries-included addition to the (already great) standard library, complementing it, and helping developers write cleaner code.

This is an R6RS library for working with packed byte structures. It is similar to struct in Python or pack and unpack in Perl.

run64 is a SRFI-64 runner. It generates pretty, readable, colorful output featuring clear diffs between expected and actual values. run64 is meant to work with an SRFI-64 implementation, and is not an SRFI-64 implementation in itself.
