GdkPixbuf-Xlib contains the deprecated API for integrating GdkPixbuf with Xlib data types. This library was originally shipped by gdk-pixbuf, and has since been moved out of the original repository. No newly written code should ever use this library.

Murrine is a cairo-based GTK+ theming engine. It is named after the glass artworks done by Venicians glass blowers.

Cairomm provides a C++ programming interface to the Cairo 2D graphics library.

Libdatrie is an implementation of double-array structure for representing trie. Trie is a kind of digital search tree.

Volume Icon is a volume indicator and control applet for the Advanced Linux Sound Architecture. It sits in the system tray, independent of your desktop environment, and supports global key bindings.

Libpanel provides a library to create IDE-like applications using GTK and libadwaita. It has widgets for panels, docks, columns and grids of pages. Primarily, its design and implementation focus around the GNOME Builder and Drafting projects.

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.

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.

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.

Dragon is a lightweight drag-and-drop source for X where you can run:

dragon file.tar.gz

to get a window with just that file in it, ready to be dragged where you need it. What if you need to drag into something? Using:

dragon --target

you get a window you can drag files and text into. Dropped items are printed to standard output.

Cairo is a 2D graphics library with support for multiple output devices. Currently supported output targets include the X Window System (via both Xlib and XCB), Quartz, Win32, image buffers, PostScript, PDF, and SVG file output. Experimental backends include OpenGL, BeOS, OS/2, and DirectFB.

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.

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

guile-newra (newra) wants to replace the current (3.0) Guile array system, which is almost entirely implemented in C. The new implementation should be at least as fast.

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.

G-Golf port of (a subset of) the upstream gtk4-demo examples in the gtk:bin Guix package output. Run guix edit g-golf-gtk-4-examples for inspiration how to wrap G-Golf applications when writing a Guix package.

A module for GNU Guile to read and write YAML files. It works using bindings to the yaml-cpp C++ library.

This project provides Guile bindings to the DRMAA library version 1. DRMAA is a resource management library implemented by HPC cluster schedulers.

This package provides a simple SVG-based picture language for Guile. The picture values can directly be displayed in Geiser.

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.

Kracht provides helpful and convenient functionalities that can help you develop more comfortably in your Guile Scheme project. You can see it as a batteries-included addition to the (already great) standard library, complementing it, and helping developers write cleaner code.

guile-png is a GNU Guile library for working with the PNG format. This library provides API for reading and writing PNG data, as well as some graphic primitives and basic image processing filters.

Wisp is a syntax for Guile which provides a Python-like whitespace-significant language. It may be easier on the eyes for some users and in some situations.
