GtkDoc is a tool used to extract API documentation from C-code like Doxygen, but handles documentation of GObject (including signals and properties) that makes it very suitable for GTK+ apps and libraries. It uses docbook for intermediate files and can produce html by default and pdf/man-pages with some extra work.

GtkSourceView is a text widget that extends the standard GTK+ text widget GtkTextView. It improves GtkTextView by implementing syntax highlighting and other features typical of a source code editor.

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

This package provides a GdkPixbuf module for loading XMP images.

Layer Shell is a Wayland protocol for desktop shell components, such as panels, notifications and wallpapers. It can be used to anchor windows to a corner or edge of the output, or stretch them across the entire output. It supports all Layer Shell features including popups and popovers.

GdkPixbuf is a library that loads image data in various formats and stores it as linear buffers in memory. The buffers can then be scaled, composited, modified, saved, or rendered.

GTK+, or the GIMP Toolkit, is a multi-platform toolkit for creating graphical user interfaces. Offering a complete set of widgets, GTK+ is suitable for projects ranging from small one-off tools to complete application suites.

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.

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 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.

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.

Irregex is an s-expression based alternative to your classic string-based regular expressions. It implements SRFI 115 and is deeply inspired by the SCSH regular expression system.

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

This package provides a library (lsp-server) and an executable guile-lsp-server that can be used by LSP clients in order to provide IDE functionality for Guile Scheme.

Haunt is a static site generator written in Guile Scheme. Haunt features a functional build system and an extensible interface for reading articles in any format.

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

Guile Shapefile is a Guile library for reading shapefiles.

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.
