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).

This library implements a JavaScript Object Notation (JSON) parser and printer. It also supports parsing JSON objects that may be bigger than memory with a streaming API.

guile-filesystem provides a set of utility functions, that augment Guile's support for handling files and their names.

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.

guile-custom-port overrides Guile's port modules to bring the custom ports from Guile 3.10 to previous versions.

This Guile library provides instrumentation code intended to be used with the Prometheus time series service. Counter, gauge and histogram metric types are supported.

This package provides a Guile Scheme wrapper for libgsl.so. Implements

• GSL vectors.

• Matrices.

• BLAS operations.

• Eigensystem solutions.

• One-dimensional root solvers.

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 bindings for Avahi. It allows programmers to use functionalities of the Avahi client library from Guile Scheme programs. Avahi itself is an implementation of multicast DNS (mDNS) and DNS Service Discovery (DNS-SD).

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.

Guile-bstructs provides an efficient implementation of low-level binary structures for Guile Scheme inspired by Chez Scheme's ftypes.

Guile-GI is a library for Guile that allows using GObject-based libraries, such as GTK+3. Its README comes with the disclaimer: This is pre-alpha code.

run64 is a SRFI-64 runner. It generates pretty, readable, colorful output featuring clear diffs between expected and actual values. run64 is meant to work with an SRFI-64 implementation, and is not an SRFI-64 implementation in itself.

GNU Mcron is a complete replacement for Vixie cron. It is used to run tasks on a schedule, such as every hour or every Monday. Mcron is written in Guile, so its configuration can be written in Scheme; the original cron format is also supported.

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.

guile-dbi is a library for Guile that provides a convenient interface to SQL databases. Database programming with guile-dbi is generic in that the same programming interface is presented regardless of which database system is used. It currently supports MySQL, Postgres and SQLite3.

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.

guile-aspell is a Guile Scheme library for comparing a string against a dictionary and suggesting spelling corrections.

This library provides a reference implementation for SRFI-197. This SRFI defines a family of chain and nest pipeline operators, which can rewrite nested expressions like (a b (c d (e f g))) as a sequence of operations: (chain g (e f _) (c d _) (a b _)).

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

This package provides a Guile programming interface to the ZeroMQ messaging library.

guile-email is a collection of email utilities implemented in pure guile. It supports parsing MIME (Multipurpose Internet Mail Extensions) compliant email messages and reading emails from the mbox format.

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