This package provides an R7RS Scheme library that serializes Scheme data to the KDL document language, supporting both version 1 and version 2 of the specification. It models the KDL data model—nodes with ordered arguments, unordered properties, and nested children—as plain Scheme records and renders them to text. KDL v2 is the default output dialect; KDL v1 output is available on request.

Emacsy is an embeddable Emacs-like library that uses GNU Guile as extension language. Emacsy can give a C program an Emacsy feel with keymaps, minibuffer, recordable macros, history, tab completion, major and minor modes, etc., and can also be used as a pure Guile library. It comes with a simple counter example using FreeGLUT and browser examples in C using Gtk+-3 and WebKitGtk.

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 project provides Guile bindings to the DRMAA library version 1. DRMAA is a resource management library implemented by HPC cluster schedulers.

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

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-sundown is a library that renders Markdown as HTML. It supports many Markdown extensions including tables.

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

Guile-Udev provides GNU Guile bindings to libudev.

This package provides Guile FFI bindings for CBLAS, the library of linear algebra subprograms.

To use the bindings, import (ffi cblas). CBLAS will be loaded from the default dynamic library path. There are up to three bindings for each function: raw, typed, and functional.

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

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

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 is a collection of iteration macros for Guile. They are inspired by racket's family of iterators. Specifically, the following iterators are available:

• for

• for/map

• for/c

• for/fold

• for/fold-right

• for/folder

• folder

Hygguile is a library that allows you to create cozy web user-interfaces using Guile Scheme, by defining an expressive DSL, and by leveraging the power of S-expressions, SXML and OliveCSS.

The project aims to provide reusable, professional-looking and accessible web components, whose names resemble the HTML counterparts, thus easing the learning curve, and reducing the cognitive load.

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.

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

Guile RDF is an implementation of the RDF (Resource Description Framework) format defined by the W3C for GNU Guile. RDF structures include triples (facts with a subject, a predicate and an object), graphs which are sets of triples, and datasets, which are collections of graphs.

RDF specifications include the specification of concrete syntaxes and of operations on graphs. This library implements some basic functionalities, such as parsing and producing turtle and nquads syntax, as well as manipulating graphs and datasets.

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

Guile-Lib is intended as an accumulation place for pure-scheme Guile modules, allowing for people to cooperate integrating their generic Guile modules into a coherent library. Think "a down-scaled, limited-scope CPAN for Guile". It provides the following modules:

• (apicheck) Describe and verify library programming interfaces.

• (config load) Loading configuration files.

• (container async-queue) A thread-safe message queue.

• (container nodal-tree) A tree consisting of nodes with attributes.

• (container delay-tree) A nodal tree with lazily evaluated fields.

• (debugging assert) Helpful assert macro.

• (debugging time) A simple macro to time the execution of an expression.

• (graph topological-sort) Routines to perform topological sorts.

• (htmlprag) Neil Van Dyke's permissive ("pragmatic") HTML parser.

• (io string) SLIB's IO routines dealing with strings.

• (logging logger) A flexible logging system.

• (logging port-log) A logger that outputs to a port.

• (logging rotating-log) A logger that rotates its output files.

• (match-bind) Nifty and concise regular expression routines.

• (math minima) A golden-section minimum finder.

• (math primes) Functions related to prime numbers and factorization.

• (os process) Spawning processes and capturing their output.

• (scheme documentation) Macros to define different kinds of variables with documentation.

• (scheme kwargs) Defining functions with flexible keyword arguments.

• (search basic) Classic search functions.

• (string completion) Building blocks for tab completion.

• (string soundex) The SOUNDEX string categorization algorithm.

• (string transform) Beyond SRFI-13.

• (string wrap) A versatile string formatter.

• (term ansi-color) Generate ANSI color escape sequences.

• (unit-test) A JUnit-style unit testing framework.

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 package provides a simple yaml module for Guile using the ffi-helper from nyacc.

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