Guile-JPEG is a Scheme library to parse JPEG image files and to perform geometrical transforms on JPEG images.

This package provides bindings for Avahi. It allows programmers to use functionalities of the Avahi client library from Guile Scheme programs. Avahi itself is an implementation of multicast DNS (mDNS) and DNS Service Discovery (DNS-SD).

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.

This library provides a reference implementation for SRFI-223. This SRFI defines a generalized procedures for binary search of vector-like data structures are provided which can be applied to any sequence type, including ones defined by the user, together with applications of these procedures for Scheme’s built-in vectors.

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.

guile-commonmark is a library for parsing CommonMark, a fully specified variant of Markdown. The library is written in Guile Scheme and is designed to transform a CommonMark document to SXML. guile-commonmark tries to closely follow the CommonMark spec, the main difference is no support for parsing block and inline level HTML.

Utility procedures provided by this SRFI in addition to the R6RS API may be categorized as follows:

• Constructors: alist->eq-hashtable, alist->eqv-hashtable, alist->hashtable

• Access and mutation: hashtable-lookup, hashtable-intern!

• Copying: hashtable-empty-copy

• Key/value collections: hashtable-values, hashtable-key-list, hashtable-value-list, hashtable-entry-lists

• Iteration: hashtable-walk, hashtable-update-all!, hashtable-prune!, hashtable-merge!, hashtable-sum, hashtable-map->lset, hashtable-find

• Miscellaneous: hashtable-empty?, hashtable-pop!, hashtable-inc!, hashtable-dec!

Guile Gemini is an implementation of the Gemini protocol in Guile Scheme, providing both client and server functionality. It uses GnuTLS to meet Gemini's TLS requirements, and Guile Fibers for concurrency.

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

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

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.

Guile Netlink is a GNU Guile library providing an implementation of the netlink protocol.

It provides a generic library for writing implementations of a netlink protocol, a low-level rtnetlink implementation that uses that library and a high-level API for network management that uses rtnetlink.

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.

Fortran is great in expressing operations on multi-dimensional arrays of numbers. Scheme is great at expressing your coding thoughts. This project is an attempt to combine both into something useful.

This package allows you to compile a Guile Python file to any target from tree-il.

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.

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 package provides a simple Guile interface to .env (or dotenv) files. It implements parsing of files and setting environment variables from them.

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.

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