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

G-Golf port of the upstream adwaita-1-demo example in the libadwaita Guix package. It adds one simple hello-world example as well. Run guix edit g-golf-adw-1-examples for inspiration how to wrap G-Golf applications when writing a Guix package.

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.

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.

This package provides Guile bindings for the libmosquitto MQTT client library. The bindings are written in GOOPS, and the user can extend the client class by inheritance.

Guile Hoot is a WebAssembly compiler backend for GNU Guile and standalone WASM toolchain.

This package provides a procedure for converting strings into URL-friendly slugs. A slug is a simplified version of a string, often used in URLs, that contains only lowercase letters, digits, and hyphens. This package is inspired by the slugify function in the Django web framework. It is useful for generating human-readable identifiers from arbitrary text.

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-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.

Jaro is a just another resource opener. It runs the appropriate application to open a given file or URL based on given configurations.

This package provides purely functional data structures written in R6RS Scheme and compiled for Guile. It has been tested with Racket, Guile 2, Vicare Scheme and IronScheme. Right now it contains:

• queues

• deques

• bbtrees

• sets

• dlists

• priority search queues (PSQs)

• finger trees

• sequences

• heaps

• hash array mapped tries (HAMTs).

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

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.

This package provides a Guile Scheme wrapper for libgsl.so. Implements

• GSL vectors.

• Matrices.

• BLAS operations.

• Eigensystem solutions.

• One-dimensional root solvers.

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

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

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.

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

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 an implementation of ActivityStreams and ActivityPub in Guile. It includes a full (currently demo) web server.

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

guile-png is a GNU Guile library for working with the PNG format. This library provides API for reading and writing PNG data, as well as some graphic primitives and basic image processing filters.

This package provides A Guile reader extension for `raw strings', it lets you write verbatim strings without having to escape double quotes.

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