This package provides Guile bindings to the libsodium cryptographic library which provides core cryptographic primitives needed to build higher-level tools.

Guile-syntax-highlight is a general-purpose syntax highlighting library for GNU Guile. It can parse code written in various programming languages into a simple s-expression that can be converted to HTML (via SXML) or any other format for rendering.

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

This package provides a simple SVG-based picture language for Guile. The picture values can directly be displayed in Geiser.

guile-sjson is a json reader/writer for Guile. It has a nice, simple s-expression based syntax.

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

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-PG is a collection of modules for Guile allowing access to the PostgreSQL RDBMS from Scheme programs.

This has been tested against PostgreSQL 10 through 13, but currently only works with Guile 1.4.x to 2.0.x.

Guile-DSV is a GNU Guile module for working with the delimiter-separated values (DSV) data format. Guile-DSV supports the Unix-style DSV format and RFC 4180 style format. Also Guile-DSV includes a console program named dsv that allows to view and process DSV data, including such operations as delimiter change, conversion from one DSV standard to another and printing the data as pseudographics tables.

This package provides an Automake test driver that can run SRFI 64 test suites. It gives Automake insight into the individual tests being run, resulting clearer and more specific output.

The (file-names) module provides tools for manipulating file names. The module was built on the idea that doing anything more than a non-trivial modification of a file name string is a pain (making sure all slashes are present and accounted for, resolving . and .., etc). Inevitably, you have to break the string up into chunks and operate on that list of components. This module takes care of that for you.

This package provides a DSL for a number of Amazon Web Services (AWS) APIs, including EFS, EC2, Route53, and more. Guile AWS uses the Guile compiler tower to generate the DSL from AWS JSON specifications.

This library provides a reference implementation for SRFI-223. This SRFI defines a generalized procedures for binary search of vector-like data structures are provided which can be applied to any sequence type, including ones defined by the user, together with applications of these procedures for Scheme’s built-in vectors.

This package provides extensible Guile bindings for the Sway window manager. It can be used to query Sway, assign keybindings and listen to events in Guile.

Utility procedures provided by this SRFI in addition to the R6RS API may be categorized as follows:

• Constructors: alist->eq-hashtable, alist->eqv-hashtable, alist->hashtable

• Access and mutation: hashtable-lookup, hashtable-intern!

• Copying: hashtable-empty-copy

• Key/value collections: hashtable-values, hashtable-key-list, hashtable-value-list, hashtable-entry-lists

• Iteration: hashtable-walk, hashtable-update-all!, hashtable-prune!, hashtable-merge!, hashtable-sum, hashtable-map->lset, hashtable-find

• Miscellaneous: hashtable-empty?, hashtable-pop!, hashtable-inc!, hashtable-dec!

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 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).

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.

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