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.

GuileScript is a toy compiler that aims to compile Guile to JavaScript. It currently does not do much, but it might in the future.

Guile-ERIS is a Guile implementation of the Encoding for Robust Immutable Storage (ERIS). ERIS allows arbitrary content to be encoded into uniformly sized, encrypted blocks that can be reassembled using a short read-capability.

Guile Gemini is an implementation of the Gemini protocol in Guile Scheme, providing both client and server functionality. It uses GnuTLS to meet Gemini's TLS requirements, and Guile Fibers for concurrency.

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 an implementation of SRFI 158 for Guile. SRFI 158 defines utility procedures that create, transform, and consume generators. It also defines procedures that return accumulators. It is implemented by wrapping the sample implementation in a thin Guile compatibility layer.

guile-xapian provides Guile bindings for Xapian, a search engine library. Xapian is a highly adaptable toolkit which allows developers to easily add advanced indexing and search facilities to their own applications. It has built-in support for several families of weighting models and also supports a rich set of boolean query operators.

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

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.

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

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

Guile-SMC is a state machine compiler that allows users to describe finite state machines (FSMs) in Scheme in terms of transition tables. It is capable to generate such transition tables from a PlantUML state diagrams.

A transition table can be verified and checked for dead-ends and infinite loops. Also Guile-SMC FSMs gather statistics when they run.

Guile-SMC comes with a Scheme program called smc -- a state machine compiler itself. It produces a Scheme code for an FSM from the PlantUML format. This tool is meant to be called on a PlantUML file when a program with a FSM is being built (for example, from a Makefile.)

Guile port of racket-algorithms, a package containing useful algorithms borrowed from other programming languages).

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.

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 bindings for Newt, a programming library for color text mode, widget based user interfaces. The bindings are written in pure Scheme by using Guile’s foreign function interface.

This is Emacs with a few settings that make working with Guile easier for people new to Emacs. Features include: CUA mode, Geiser, tool bar icons to evaluate Guile buffers, support for Guile's very own picture language, code completion, a simple mode line, etc.

This library provides the sample implementation of SRFI-165. This SRFI defines an environment monad, which models computations that depend on values from a shared environment. These computations can read values from the environment, pass values to subsequent computations, execute sub-computations in an extended environment, and modify the environment for future computations.

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.

bewaking provides functionalities to (double) encrypt and decrypt data, aided by a custom obfuscation algorithm.

It also provides a DSL to be used for Authorization and Authentication for your Guile Scheme projects with a simple user permission system.

Data is protected through multiple layers of cryptography techniques and obfuscation tricks, producing secure files and tokens one can use.

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.

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

G-Golf port of the upstream adwaita-1-demo example in the libadwaita Guix package. It adds one simple hello-world example as well. Run guix edit g-golf-adw-1-examples for inspiration how to wrap G-Golf applications when writing a Guix package.

MiniKanren is a relational programming extension to the Scheme programming Language, written as a smaller version of Kanren suitable for pedagogical purposes. It is featured in the book, The Reasoned Schemer, written by Dan Friedman, William Byrd, and Oleg Kiselyov.

This is Ian Price's r6rs packaged version of miniKanren, which deviates slightly from miniKanren mainline.
