The GNU extension language

Projects List

This page lists free software projects that use or enhance the current stable version of Guile. To have your project listed here or to contribute, ask for instructions on the guile-user mailing list.

Note: If you want your project to appear here on the GNU site, then you must include licensing information, and the license has to be acceptably free.

Older Guile projects, e.g., software that might not run with the current stable version of Guile, are listed here.

Core Projects

These projects modify or enhance the innards of Guile.

Guile-Lib

description	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".
license	LGPL 2.1 or later

Guile-Reader

description	Guile-Reader is a toolkit to build readers for Guile, making it easy to extend the syntax. It makes it possible to have several coexisting readers, recognizing different syntaxes.
license	LGPL 2.1 or later

Guile-VM

description

The master branch of Guile's repository contains a bytecode compiler and companion virtual machine (VM). These will be part of the stable series that will follow the 1.8 series. The former vm branch was merged on March 14th, 2009, into master. On June 19th, 2009, GNU Guile 1.9.0 was released; it is the first pre-release of what will eventually become the 2.0 series, including the compiler and VM. Please check the mailing lists for more information.

LGPL 3 or later

Guile with BDW-GC

description

The master branch of Guile's repository uses the Boehm-Demers-Weiser conservative garbage collector (BDW-GC) as a substitute for Guile's own garbage collector. This has been the case since the former boehm-demers-weiser-gc branch was merged, which was shortly before the 1.9.3 pre-release. A summary of the motivations behind this work is available here. Comparative benchmarks can be seen here. Implementation details (older, but still valid) are given here. Please check the mailing lists for more information.

Graphical User Interfaces

Projects that provide support for the creation of graphical user interfaces (GUIs).

GuCu (Guile Curses)

description	GuCu provides bindings of the NCurses library, allowing the implementation of text-mode user interfaces.
license	GPL 2 or later

GNU Guile-GNOME

description	Guile-GNOME provides bindings for the entire GNOME library stack: from Pango to GnomeCanvas, Gtk+ to GStreamer, Glade to GtkSourceView, etc.
license	GPL 2 or later

GNU Guile-GTK

description	Guile-GTK provides bindings to the GTK+ toolkit from Guile.
license	GPL

libRUIN

description	libRUIN (Renderer for User Interfaces in Ncurses) is a rendering library for various XML-based user interface markup languages (such as Mozilla XUL), using the Ncurses terminal control library as a rendering target. GNU Guile and the SDOM Scheme module are used as the "glue" that manages user input and event handling.
license	GPL

File Formats

Tools and libraries to read and produce specific file formats.

Networking

These projects provide Guile modules for networking.

GnuTLS

description	Guile 1.8 bindings for the GnuTLS library, an implementation of the Transport Layer Security (TLS) protocol
license	LGPL 2 or later + GPL 2 or later

Guile-Avahi

description	Guile 1.8 bindings for Avahi, an implementation of the mDNS and DNS-SD protocol. The latter provides service discovery mechanisms.
license	LGPL v3 or later

GNU Guile-RPC

description	GNU Guile-RPC is an implementation of ONC RPC and XDR (standardized as RFC 1831 and RFC 4506) in Guile Scheme, and for use by Guile programs.
license	LGPL v3 or later

SCSS

description	SCSS is an implementation in Scheme of the W3C CSS recommendation (version 2.1). It provides a framework for parsing user-supplied style information and for querying the resulting cascade using SXML/SDOM documents or plain text.
license	GPL

Tools

These projects are tools for or implemented with Guile. Mostly, these are the types of things that automate documentation or code generation.

GNU AutoGen

description	AutoGen is a tool designed for generating program files that contain repetitive text with varied substitutions. Its goal is to simplify the maintenance of programs that contain large amounts of repetitious text. This is especially valuable if there are several blocks of such text that must be kept synchronized.
license	GPL for the AutoGen engine, LGPL for the POSIX and GNU compliant option processing

Guile-Lint

description	Syntactic and semantic checks on Guile programs and modules. Picks up things like unbound variables in hard-to-reach places.
license	GPL 2 or later

Applications

These projects are applications using Guile: either C programs that allow extension via Scheme, or Scheme programs written for Guile.

Beast

description	Beast is a music composition and synthesis tool.
license	GPL 2 or later, LGPL 2.1 or later

BOKIN

description	BOKIN is an accounting system based on double-entry bookkeeping. Since BOKIN is batch-based system, it doesn't require any GUI. BOKIN is free software, and a commercial software based on the BOKIN model.
license	GPL 3 or later

GNU LilyPond

description	LilyPond generates beautiful music notation from an input file.
license	GPL

Skribilo

description	Skribilo is a document authoring system that can produce output in a variety of formats including HTML and PDF from a single input format. It is implemented in Scheme and highly customizable and programmable.
license	GPL 2 or later

Snd

description	Snd is a sound editor.
license	LGPL

GNU TeXmacs

description

GNU TeXmacs is a free WYSIWYW editing platform with special features for scientists. The software aims to provide a unified and user friendly framework for editing structured documents with different types of content (text, graphics, mathematics, interactive content, etc.). The rendering engine uses high-quality typesetting algorithms so as to produce professionally looking documents, which can either be printed out or presented from a laptop. New presentation styles can be written by the user and new features can be added to the editor using the Scheme extension language.

XChat-Guile

description	XChat-Guile is a plugin for XChat that enables XChat plugin writers to write their plugins in Scheme language. Since it uses libguile, the plugin writers can do almost everything that they can do with guile. e.g It is possible to do all kinds of gnome stuff using the guile-gnome modules.
license	GPL
