The (hashing …) modules implement cryptographic hash functions in pure R6RS Scheme: CRC, HMAC, MD5, SHA-1, and SHA-2 (SHA-256, SHA-512).

This is a serialization library for serializing objects like classes and objects, closures and structs. This currently does not support serializing continuations or delimited continuations.

Guile-SDL2 provides Guile Scheme bindings for the SDL2 C shared library. The bindings are written in pure Scheme using Guile's foreign function interface.

This package provides Guile bindings for zlib, a lossless data-compression library. The bindings are written in pure Scheme by using Guile's foreign function interface.

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.

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 bindings for Newt, a programming library for color text mode, widget based user interfaces. The bindings are written in pure Scheme by using Guile’s foreign function interface.

guile-curl is a project that has procedures that allow Guile to do client-side URL transfers, like requesting documents from HTTP or FTP servers. It is based on the curl library.

Asynchronous Reliable Extensible Sleek RPC Server for Guile. It's based on nREPL protocol and can be used for programmable interactions with a running guile processes, for implementing REPLs, IDEs, test runners or other tools.

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.

This is an R6RS Scheme adaptation of the packrat parsing. Packrat parsing is a memoizing, backtracking, recursive-descent parsing technique that runs in time and space linear in the size of the input text.

This is an R6RS Scheme library that provides a reader with some extra features not found in the standard read procedure such as a compatible mode with support for other RnRS standards and a tolerant mode that continues on errors.

Veritas is a testing framework for Guile with an EDSL to define test suites. Emphasis is placed on legibility and maintainability of tests. Veritas shuffles tests and runs them concurrently by default to ensure robust testing practices.

GNU Guile QR code generator that can create QR codes from text and binary data. The resulting QR codes can be rendered to ASCII art strings or to PNG images (using Guile-PNG API.)

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-Lens is a library implementing lenses in Guile. The library is currently a re-implementation of the lentes library for Clojure. Lenses provide composable procedures, which can be used to focus, apply functions over, or update a value in arbitrary data structures.

Guile Netlink is a GNU Guile library providing an implementation of the netlink protocol.

It provides a generic library for writing implementations of a netlink protocol, a low-level rtnetlink implementation that uses that library and a high-level API for network management that uses rtnetlink.

Guile-JSON supports parsing and building JSON documents according to the specification. These are the main features:

• Strictly complies to specification.

• Build JSON documents programmatically via macros.

• Unicode support for strings.

• Allows JSON pretty printing.

This package provides an implementation of AA trees, a self-balancing binary tree data structure, for Guile. It ensure O(log n) worst case performance for core operations. The module provides non-mutating insert, delete, and search operations, with support for convenient nested tree operations.

GNU Zile is a lightweight clone of the Emacs editor, and Zile-on-Guile is a variant of Zile that can be extended in Guile Scheme. Hitting M-C (or: Alt and C) brings up a Guile REPL from which interactive functions akin to those of Emacs can be invoked.

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 purely functional data structures written in R6RS Scheme and compiled for Guile. It has been tested with Racket, Guile 2, Vicare Scheme and IronScheme. Right now it contains:

• queues

• deques

• bbtrees

• sets

• dlists

• priority search queues (PSQs)

• finger trees

• sequences

• heaps

• hash array mapped tries (HAMTs).
