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

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.

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-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.

Guildhall is a package manager written for Guile Scheme. A guild is an association of independent craftspeople. A guildhall is where they meet. This Guildhall aims to make a virtual space for Guile wizards and journeyfolk to share code.

On a practical level, Guildhall lets you share Scheme modules and programs over the internet, and install code that has been shared by others. Guildhall can handle dependencies, so when a program requires several libraries, and each of those has further dependencies, all of the prerequisites for the program can be installed in one go.

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.

The Concise Binary Object Representation (CBOR), as specified by RFC 8949, is a binary data serialization format. CBOR is similar to JSON but serializes to binary which is smaller and faster to generate and parse. This package provides a Guile implementation of CBOR.

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.

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

This SRFI defines two disjoint immutable container types known as Maybe and Either, both of which can contain objects collectively known as their payload. A Maybe object is either a Just object or the unique object Nothing (which has no payload); an Either object is either a Right object or a Left object. Maybe represents the concept of optional values; Either represents the concept of values which are either correct (Right) or errors (Left).

f.scm is a library intended to facilitate working with files and directories (the file system in general). It was initially inspired by the f library for Emacs.

guile-sundown is a library that renders Markdown as HTML. It supports many Markdown extensions including tables.

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.

GNU 8sync (pronounced "eight-sync") is an asynchronous programming library for GNU Guile based on the actor model.

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

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.

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.

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!

AC/D-Bus is an implementation of the D-Bus wire protocol. D-Bus is an interprocess communication protocol popular on GNU/Linux systems to communicate with a variety of services. Originally designed for desktop environments, it is now used by programs like VLC media player, BlueZ, NetworkManager, Pulseaudio, systemd (including logind and resolved), Polkit, gnome-keyring, and many more.

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.

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-Daemon is a small Guile program that loads your initial configuration file, and then reads and evaluates Guile expressions that you send to a FIFO file.

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.
