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.

Guile-websocket provides an implementation of the WebSocket protocol as defined by RFC 6455.

guile-kolam is a GraphQL implementation for Scheme. kolam features a parser to parse and serialize GraphQL documents, a type system to create GraphQL schemas, an execution engine to execute GraphQL queries, and a HTTP handler to implement a HTTP GraphQL endpoint.

To query and change settings of serial devices on POSIX systems, the termios API is used. GNU Guile doesn't have an interface for that built in. This module implements this interface by use of Guile's dynamic FFI.

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.

This package provides an implementation of SRFI 146 for Guile. SRFI 146 defines datastructures that implement mappings (finite sets of associations consisting of a key and a value). Two types of mappings are defined: One using a comparator to define an order on the keys and another using a hash function on the keys. The datastructures and procedures are by default purely-functional. This package re-uses the SRFI sample implementation that is based on red-black trees and Hash Array Mapped Trie (HAMT).

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

The (jtd) module for Guile provides a procedure jump-to-debugger for escaping to the Guile REPL for the purpose of debugging code.

guile-commonmark is a library for parsing CommonMark, a fully specified variant of Markdown. The library is written in Guile Scheme and is designed to transform a CommonMark document to SXML. guile-commonmark tries to closely follow the CommonMark spec, the main difference is no support for parsing block and inline level HTML.

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.

MiniKanren is a relational programming extension to the Scheme programming Language, written as a smaller version of Kanren suitable for pedagogical purposes. It is featured in the book, The Reasoned Schemer, written by Dan Friedman, William Byrd, and Oleg Kiselyov.

This is Ian Price's r6rs packaged version of miniKanren, which deviates slightly from miniKanren mainline.

See http://minikanren.org/ for more on miniKanren generally.

This package provides a procedure for converting strings into URL-friendly slugs. A slug is a simplified version of a string, often used in URLs, that contains only lowercase letters, digits, and hyphens. This package is inspired by the slugify function in the Django web framework. It is useful for generating human-readable identifiers from arbitrary text.

This package provides Guile bindings to the Tree-sitter parsing library.

This package provides macros for functional chaining in Guile, similar to UNIX pipes (|), Clojure's threading macros (-> and ->>).

This package provides Guile bindings for the taglib C library. It can be used to access and modify metadata for audio files.

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).

guile-avatar helps you to determine avatars (or profile pictures) for email addresses using the Libravatar specification.

This package provides a simple Guile interface to .env (or dotenv) files. It implements parsing of files and setting environment variables from them.

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.

Gulie-CoAP is a Guile implementation of the Constrained Application Protocol (CoAP). CoAP is a network transport protocol specialized for use with constrained nodes and constrained networks (e.g. low-power, lousy). This library implements basic serialization of CoAP messages over UDP (RFC 7252) and TCP (RFC 8323) as well as an asynchronous TCP client (using guile-fibers).

This is a web-driver, or Selenium 2, client. It's purpose is to automate browsers, specifically for automatic web server testing. Chrome or Firefox can be used as the automated browsers, or it can connect to arbitrary server providing webdriver interface. The client implements most of the WebDriver specification.

guile-web-driver-ng also provides a proxy implemented as a Guile module. If configured, the proxy can intercept and modify HTTP/HTTPS traffic (for example, add, delete and replace HTTP headers) which is useful for Selenium WebDriver as it does not provide a way to change the headers on its own.

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.

Guile-ICS is an iCalendar (RFC5545) and vCard (RFC6350) format parser library written in pure Scheme. The library can be used to read and write iCalendar/vCadr data and convert the data from/to various formats.

The library is shipped with documentation in Info format and usage examples.
