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

guile-tap is a library for GNU Guile that implements a framework for specifying test cases that emit output that adheres to the Test Anything Protocol (TAP). It comes with an experimental harness (tap-harness).

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.

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

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).

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 a Guile Scheme wrapper for libgsl.so. Implements

• GSL vectors.

• Matrices.

• BLAS operations.

• Eigensystem solutions.

• One-dimensional root solvers.

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-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.

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.

This package provides an implementation of SRFI 128 for Guile. SRFI 128 defines comparators, which bundles a test type predicate, an equality predicate, an ordering predicate and a hash function into a single Scheme object. This can be used in the implementation of data structures. This package re-uses the SRFI sample implementation.

guile-goblins is the Guile version of Spritely Goblins, a transactional, distributed programming environment following object capability security designs. Goblins is a general toolkit, and also the core layer of Spritely's work to support healthy distributed networked communities. Goblins allows for cooperation between networked programs in a mutually suspicious network through OCapN, the Object Capability Network. This includes collaboration across runtimes; for instance, programs written in the Guile and Racket versions of Goblins are able to speak to each other.

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

Guile-colorized provides you with a colorized REPL for GNU Guile.

guile-ncurses provides Guile language bindings for the ncurses library.

Guile-websocket provides an implementation of the WebSocket protocol as defined by RFC 6455.

This project provides a pure Scheme implementation of Protocol Buffers, including parsing and code generation.

This package provides A Guile reader extension for `raw strings', it lets you write verbatim strings without having to escape double quotes.

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.

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.

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

Guile-Quickcheck is a library for random testing of program properties inspired by ghc-quickcheck. You can use it to express properties, which functions should satisfy, as Scheme code and then check whether they hold in a large number of randomly generated test cases.

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.

This library implements parts of the JSON-RPC specification, allowing for calling methods on remote servers by exchanging JSON objects.
