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.

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:

• (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 C bindings for wayland shared memory (SHM). Exposes simple procedures: wl_shm_create_wrapper, wl_shm_allocate_wrapper, wl_shm_munmap, wl_shm_mmap Probably can be replaced with guile's built-in file-descriptor procedures.

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.

G-Golf (Gnome: (Guile Object Library for)) is a library for developing modern applications in Guile Scheme. It comprises a direct binding to the GObject Introspection API and higher-level functionality for importing Gnome libraries and making GObject classes (and methods) available in Guile's object-oriented programming system, GOOPS.

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-ICS is an iCalendar (RFC5545) and vCard (RFC6350) format parser library written in pure Scheme. The library can be used to read and write iCalendar/vCadr data and convert the data from/to various formats.

The library is shipped with documentation in Info format and usage examples.

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

guile-email is a collection of email utilities implemented in pure guile. It supports parsing MIME (Multipurpose Internet Mail Extensions) compliant email messages and reading emails from the mbox format.

This tiny package provides some procedures and macros to extend Guile Scheme procedure composition facilities. For example, there is a compose-top, a reverse-order analog to native compose procedure. The compose-cont is a macro, utilizing some power of continuations to build really flexible flows.

This library is intended to stay basic and small, so it has no any external dependencies and can be a good base for other packages, like e.g. guile-web-middleware.

This SRFI defines two disjoint immutable container types known as Maybe and Either, both of which can contain objects collectively known as their payload. A Maybe object is either a Just object or the unique object Nothing (which has no payload); an Either object is either a Right object or a Left object. Maybe represents the concept of optional values; Either represents the concept of values which are either correct (Right) or errors (Left).

This package provides a Guile library to parse command line arguments into structured objects. It allows declaring arguments through a small DSL, then call a procedure to parse the command line into a structured object.

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.

G-Wrap is a tool and Guile library for generating function wrappers for inter-language calls. It currently only supports generating Guile wrappers for C functions. Given a definition of the types and prototypes for a given C interface, G-Wrap will automatically generate the C code that provides access to that interface and its types from the Scheme level.

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.

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 an implementation of AA trees, a self-balancing binary tree data structure, for Guile. It ensure O(log n) worst case performance for core operations. The module provides non-mutating insert, delete, and search operations, with support for convenient nested tree operations.

This package provides functions to generate Guix manifests interactively. It works by scanning an alist of package categories, to ask the user which package sets would they like to install from it.
