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

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

The Assistive Technology Service Provider Interface, core components, is part of the GNOME accessibility project.

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.

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

GTK 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.

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.

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

Guile-Present defines a declarative vocabulary for presentations, together with tools to render presentation documents as SVG or PDF. Guile-Present can be used to make presentations programmatically, but also includes a tools to generate PDF presentations out of Org mode and Texinfo documents.

Guile-Cairo wraps the Cairo graphics library for Guile Scheme. Guile-Cairo is complete, wrapping almost all of the Cairo API. It is API stable, providing a firm base on which to do graphics work. Finally, and importantly, it is pleasant to use. You get a powerful and well-maintained graphics library with all of the benefits of Scheme: memory management, exceptions, macros, and a dynamic programming environment.

gtksourceviewmm is a portable C++ library that extends the standard GTK+ framework for multiline text editing with support for configurable syntax highlighting, unlimited undo/redo, search and replace, a completion framework, printing and other features typical of a source code editor.

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-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.

This library implements a JavaScript Object Notation (JSON) parser and printer. It also supports parsing JSON objects that may be bigger than memory with a streaming API.

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).

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

This package provides Guile modules to interface with the OAuth and OAuth2 protocols.

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

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.

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.

This package provides facilities for working with .torrent or metainfo files. Implements a bencode reader and writer according to Bitorrent BEP003.

This package provides SRFI-89 optional positional and named parameters, which define* and lambda* special forms

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).
