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

This package provides the functionality to query a SPARQL endpoint. Additionally, it provides an interface to write SPARQL queries using S-expressions.

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.

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

guile-dns is a DNS library written in pure Guile Scheme.

This is a collection of iteration macros for Guile. They are inspired by racket's family of iterators. Specifically, the following iterators are available:

• for

• for/map

• for/c

• for/fold

• for/fold-right

• for/folder

• folder

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.

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

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.

Schmutz is a header-only library to declare Scheme bindings for C++ code using a simple embedded DSL. Think of it as Boost.Python or LuaBind but for Scheme.

Guile-redis provides a Scheme interface to the Redis key-value cache and store.

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-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.

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!

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

Kracht provides helpful and convenient functionalities that can help you develop more comfortably in your Guile Scheme project. You can see it as a batteries-included addition to the (already great) standard library, complementing it, and helping developers write cleaner code.

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.

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-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.

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

Additionally, this package provides a dotenv command, exposes part of the guile-dotenv Guile API as command lines invocations.

This package provides functions to generate Guix manifests interactively. It works by scanning an alist of package categories, to ask the user which package sets would they like to install from it.

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

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.
