• queues

• deques

• bbtrees

• sets

• dlists

• priority search queues (PSQs)

• finger trees

• sequences

• heaps

• hash array mapped tries (HAMTs).

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

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.

guile-jwt is a JSON Web Token module for Guile. JSON Web Tokens are an open, industry standard (RFC 7519) method for representing claims securely between two parties. guile-jwt allows you to decode, verify and generate JWT. Supported algorithms: HS256, HS384, HS512.

This package provides Guile FFI bindings for CBLAS, the library of linear algebra subprograms.

To use the bindings, import (ffi cblas). CBLAS will be loaded from the default dynamic library path. There are up to three bindings for each function: raw, typed, and functional.

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". It provides the following modules:

• (apicheck) Describe and verify library programming interfaces.

• (config load) Loading configuration files.

• (container async-queue) A thread-safe message queue.

• (container nodal-tree) A tree consisting of nodes with attributes.

• (container delay-tree) A nodal tree with lazily evaluated fields.

• (debugging assert) Helpful assert macro.

• (debugging time) A simple macro to time the execution of an expression.

• (graph topological-sort) Routines to perform topological sorts.

• (htmlprag) Neil Van Dyke's permissive ("pragmatic") HTML parser.

• (io string) SLIB's IO routines dealing with strings.

• (logging logger) A flexible logging system.

• (logging port-log) A logger that outputs to a port.

• (logging rotating-log) A logger that rotates its output files.

• (match-bind) Nifty and concise regular expression routines.

• (math minima) A golden-section minimum finder.

• (math primes) Functions related to prime numbers and factorization.

• (os process) Spawning processes and capturing their output.

• (scheme documentation) Macros to define different kinds of variables with documentation.

• (scheme kwargs) Defining functions with flexible keyword arguments.

• (search basic) Classic search functions.

• (string completion) Building blocks for tab completion.

• (string soundex) The SOUNDEX string categorization algorithm.

• (string transform) Beyond SRFI-13.

• (string wrap) A versatile string formatter.

• (term ansi-color) Generate ANSI color escape sequences.

• (unit-test) A JUnit-style unit testing framework.

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-extensible-match is an implementation of SRFI-262. It provides user extensible pattern matching syntax. This implementation use a range of optimizations to generate efficient matching code.

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.

This package provides a Guile library to parse command line arguments into structured objects. It allows declaring arguments through a small DSL, then call a procedure to parse the command line into a structured object.

This is Emacs with a few settings that make working with Guile easier for people new to Emacs. Features include: CUA mode, Geiser, tool bar icons to evaluate Guile buffers, support for Guile's very own picture language, code completion, a simple mode line, etc.

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.

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).
