GNU Mcron is a complete replacement for Vixie cron. It is used to run tasks on a schedule, such as every hour or every Monday. Mcron is written in Guile, so its configuration can be written in Scheme; the original cron format is also supported.

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-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 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.

This package provides an implementation of AA trees, a self-balancing binary tree data structure, for Guile. It ensure O(log n) worst case performance for core operations. The module provides non-mutating insert, delete, and search operations, with support for convenient nested tree operations.

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).

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.

squee is a Guile library for connecting to PostgreSQL databases using Guile's foreign function interface.

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.

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-XOSD provides Guile bindings for libxosd, the X On Screen Display library.

Lokke intends to provide a full dialect of Clojure for Guile. It also consists of a set of Guile modules providing some of Clojure's functionality in two different guises.

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.

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

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

This package provides purely functional data structures written in R6RS Scheme and compiled for Guile. It has been tested with Racket, Guile 2, Vicare Scheme and IronScheme. Right now it contains:

• queues

• deques

• bbtrees

• sets

• dlists

• priority search queues (PSQs)

• finger trees

• sequences

• heaps

• hash array mapped tries (HAMTs).

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

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.

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-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.
