Pangomm provides a C++ programming interface to the Pango text rendering library.

GTKmm is the official C++ interface for the popular GUI library GTK+. Highlights include typesafe callbacks, and a comprehensive set of widgets that are easily extensible via inheritance. You can create user interfaces either in code or with the Glade User Interface designer, using libglademm. There's extensive documentation, including API reference and a tutorial.

LibThai is a set of Thai language support routines aimed to ease developers’ tasks to incorporate Thai language support in their applications.

GtkSpell provides word-processor-style highlighting and replacement of misspelled words in a GtkTextView widget.

Pango is a library for laying out and rendering of text, with an emphasis on internationalization. Pango can be used anywhere that text layout is needed, though most of the work on Pango so far has been done in the context of the GTK+ widget toolkit. Pango forms the core of text and font handling for GTK+-2.x.

Guile-XCB implements the XCB protocol and provides all the tools necessary to write X client code in Guile Scheme without any external dependencies.

Guile-WM is a simple window manager that's completely customizable—you have total control of what it does by choosing which modules to include. Included with it are a few modules that provide basic TinyWM-like window management, some window record-keeping, multi-monitor support, and emacs-like keymaps and minibuffer. At this point, it's just enough to get you started.

Topological sorting is an algorithm that takes a graph consisting of nodes and other nodes that depend on them, forming a partial order, and returns a list representing a total ordering of the graph. If the graph is cyclic, the topological sort will fail. The procedure topological-sort returns three values. If sorting succeeds, the first value contains the result and the second and third are #false. If sorting fails, the result is #false and the second and third value may provide additional information about the error.

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.

R7RS-small Scheme library for reading and writing RSV data format, a very simple binary format for storing tables of strings. It is a competitor for CSV (Comma Separated Values) and TSV (Tab Separated Values). Its main benefit is that the strings are represented as Unicode encoded as UTF-8, and the value and row separators are byte values that are never used in UTF-8, so the strings do not need any error prone escaping and thus can be written and read verbatim.

The RSV format is specified in https://github.com/Stenway/RSV-Specification.

This library implements immutable ropes for GNU Guile. A rope is a data structure that represents text strings. It is useful for text editing, because text can be inserted at an arbitrary point without requiring the moving of a lot of data.

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

Hall is a command-line application and a set of Guile libraries that allow you to quickly create and publish Guile projects. It allows you to transparently support the GNU build system, manage a project hierarchy & provides tight coupling to Guix.

Guile Knots is a collection of patterns and functionality that is useful when using Guile Fibers. This includes higher level concurrency utilities, support for timeouts and an alternative web server implementation.

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.

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

guile-ini is a GNU Guile library for working with the INI format. This library provides API for reading and writing INI data.

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.

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.

Note: Currently, when developing with G-Golf in guix shell, there is a grafts bug in Guix. To avoid it, use Guix' --no-grafts option. Guix packages that use wrap-program are unaffected.

This package implements RFC 9562 UUIDs, and can generate versions 1 and 3-8 from that specification. It also provides parsing for UUIDs in standard hex-and-dash format of any variant and version. Conversion between binary and hex-and-dash string UUIDs is also included.

Guile-XOSD provides Guile bindings for libxosd, the X On Screen Display library.

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.

guile-ncurses provides Guile language bindings for the ncurses library.

Guile-colorized provides you with a colorized REPL for GNU Guile.
