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.

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

This package provides a simple yaml module for Guile using the ffi-helper from nyacc.

Guile-Lib is intended as an accumulation place for pure-scheme Guile modules, allowing for people to cooperate integrating their generic Guile modules into a coherent library. Think "a down-scaled, limited-scope CPAN for Guile". It provides the following modules:

• (apicheck) Describe and verify library programming interfaces.

• (config load) Loading configuration files.

• (container async-queue) A thread-safe message queue.

• (container nodal-tree) A tree consisting of nodes with attributes.

• (container delay-tree) A nodal tree with lazily evaluated fields.

• (debugging assert) Helpful assert macro.

• (debugging time) A simple macro to time the execution of an expression.

• (graph topological-sort) Routines to perform topological sorts.

• (htmlprag) Neil Van Dyke's permissive ("pragmatic") HTML parser.

• (io string) SLIB's IO routines dealing with strings.

• (logging logger) A flexible logging system.

• (logging port-log) A logger that outputs to a port.

• (logging rotating-log) A logger that rotates its output files.

• (match-bind) Nifty and concise regular expression routines.

• (math minima) A golden-section minimum finder.

• (math primes) Functions related to prime numbers and factorization.

• (os process) Spawning processes and capturing their output.

• (scheme documentation) Macros to define different kinds of variables with documentation.

• (scheme kwargs) Defining functions with flexible keyword arguments.

• (search basic) Classic search functions.

• (string completion) Building blocks for tab completion.

• (string soundex) The SOUNDEX string categorization algorithm.

• (string transform) Beyond SRFI-13.

• (string wrap) A versatile string formatter.

• (term ansi-color) Generate ANSI color escape sequences.

• (unit-test) A JUnit-style unit testing framework.

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.

This package provides an Automake test driver that can run SRFI 64 test suites. It gives Automake insight into the individual tests being run, resulting clearer and more specific output.

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 _)).

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.

This package provides bindings for GNU Parted library, a C library allowing disk partition tables creation and manipulation. The bindings are written in pure Scheme by using Guile's foreign function interface.

GNU Artanis is a web application framework written in Guile Scheme. A web application framework (WAF) is a software framework that is designed to support the development of dynamic websites, web applications, web services and web resources. The framework aims to alleviate the overhead associated with common activities performed in web development. Artanis provides several tools for web development: database access, templating frameworks, session management, URL-remapping for RESTful, page caching, and more.

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

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-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-Udev provides GNU Guile bindings to libudev.

Guile Knots is a collection of patterns and functionality that is useful when using Guile Fibers. This includes higher level concurrency utilities, support for timeouts and an alternative web server implementation.

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

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.

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 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 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.

Guile-Reader is a simple framework for building readers for GNU Guile.

The idea is to make it easy to build procedures that extend Guile’s read procedure. Readers supporting various syntax variants can easily be written, possibly by re-using existing “token readers” of a standard Scheme readers. For example, it is used to implement Skribilo’s R5RS-derived document syntax.

Guile-Reader’s approach is similar to Common Lisp’s “read table”, but hopefully more powerful and flexible (for instance, one may instantiate as many readers as needed).

Guile-Bash provides a shared library and set of Guile modules, allowing you to extend Bash in Scheme. Scheme interfaces allow you to access the following aspects of Bash:

• aliases;

• setting and getting Bash variables;

• creating dynamic variables;

• creating Bash functions with a Scheme implementation;

• reader macro for output capturing;

• reader macro for evaluating raw Bash commands.

To enable it, run:

enable -f ~/.guix-profile/lib/bash/libguile-bash.so scm

and then run scm example.scm.

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.

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.
