AC/D-Bus is an implementation of the D-Bus wire protocol. D-Bus is an interprocess communication protocol popular on GNU/Linux systems to communicate with a variety of services. Originally designed for desktop environments, it is now used by programs like VLC media player, BlueZ, NetworkManager, Pulseaudio, systemd (including logind and resolved), Polkit, gnome-keyring, and many more.

This is an R6RS Scheme adaptation of the packrat parsing. Packrat parsing is a memoizing, backtracking, recursive-descent parsing technique that runs in time and space linear in the size of the input text.

This package provides a Scheme wrapper around liblmdb.so. Most names are the same as LMDB ones, except for prefix absence. Several conveniences are added on top:

• call-with-env-and-txn, call-with-cursor, and call-with-wrapped-cursor helpers and respective with- macros.

• for-cursor procedure for cursor iteration.

• val and stat types.

• set-compare! and set-dupsort! to configure entry sorting.

• Error signaling instead of integer return values.

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.

guile-xapian provides Guile bindings for Xapian, a search engine library. Xapian is a highly adaptable toolkit which allows developers to easily add advanced indexing and search facilities to their own applications. It has built-in support for several families of weighting models and also supports a rich set of boolean query operators.

Schmutz is a header-only library to declare Scheme bindings for C++ code using a simple embedded DSL. Think of it as Boost.Python or LuaBind but for Scheme.

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

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

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.

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.

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

This package provides an implementation of SRFI 146 for Guile. SRFI 146 defines datastructures that implement mappings (finite sets of associations consisting of a key and a value). Two types of mappings are defined: One using a comparator to define an order on the keys and another using a hash function on the keys. The datastructures and procedures are by default purely-functional. This package re-uses the SRFI sample implementation that is based on red-black trees and Hash Array Mapped Trie (HAMT).

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

Guile-ERIS is a Guile implementation of the Encoding for Robust Immutable Storage (ERIS). ERIS allows arbitrary content to be encoded into uniformly sized, encrypted blocks that can be reassembled using a short read-capability.

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.

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).

GNU Guile QR code generator that can create QR codes from text and binary data. The resulting QR codes can be rendered to ASCII art strings or to PNG images (using Guile-PNG API.)

This package provides an Automake test driver that can run SRFI 64 test suites. It gives Automake insight into the individual tests being run, resulting clearer and more specific output.

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

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.

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

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.
