Procedures in this SRFI are drawn primarily from SRFI 69 and R6RS. In addition, the following sources are acknowledged:

• hash-table-mutable? procedure and the second argument of hash-table-copy (which allows the creation of immutable hash tables) are from R6RS, renamed in the style of this SRFI.

• hash-table-intern! procedure is from Racket, renamed in the style of this SRFI.

• hash-table-find procedure is a modified version of table-search in Gambit.

• procedures hash-table-unfold and hash-table-count were suggested by SRFI 1.

• procedures hash-table=? and hash-table-map were suggested by Haskell's Data.Map.Strict module.

• procedure hash-table-map->list is from Guile.

The procedures hash-table-empty?, hash-table-empty-copy, hash-table-pop!, hash-table-map!, hash-table-intersection!, hash-table-difference!, and hash-table-xor! were added for convenience and completeness.

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.)

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.

This is a web-driver, or Selenium 2, client. It's purpose is to automate browsers, specifically for automatic web server testing. Chrome or Firefox can be used as the automated browsers, or it can connect to arbitrary server providing webdriver interface. The client implements most of the WebDriver specification.

guile-web-driver-ng also provides a proxy implemented as a Guile module. If configured, the proxy can intercept and modify HTTP/HTTPS traffic (for example, add, delete and replace HTTP headers) which is useful for Selenium WebDriver as it does not provide a way to change the headers on its own.

Guile Config is a library providing a declarative approach to application configuration specification. The library provides clean configuration declaration forms, and processors that take care of: configuration file creation; configuration file parsing; command-line parameter parsing using getopt-long; basic GNU command-line parameter generation (--help, --usage, --version); automatic output generation for the above command-line parameters.

This package provides Guile bindings for the taglib C library. It can be used to access and modify metadata for audio files.

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

Guile-CV is a Computer Vision functional programming library for the Guile Scheme language. It is based on Vigra (Vision with Generic Algorithms), a C++ image processing and analysis library. Guile-CV contains bindings to Vigra C (a C wrapper to most of the Vigra functionality) and is enriched with pure Guile Scheme algorithms, all accessible through a nice, clean and easy to use high level API.

Guile-extensible-match is an implementation of SRFI-262. It provides user extensible pattern matching syntax. This implementation use a range of optimizations to generate efficient matching code.

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

Provides bindings for GNOME's libnotify C library to 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-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 implements parts of the JSON-RPC specification, allowing for calling methods on remote servers by exchanging JSON objects.

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

This package contains helper functions for working with file system locations.

This package provides an implementation of SRFI-232, which describes curried, a variant of lambda that creates true curried procedures which also behave just like ordinary Scheme procedures. They can be applied to their arguments one by one, all at once, or anywhere in between, without any novel syntax. curried also supports nullary and variadic procedures, and procedures created with it have predictable behavior when applied to surplus arguments.

This SRFI contains various procedures that accept and return procedures, as well as a few others, drawn from an earlier version of Chicken. Common Lisp has a few of them too, and more come from the Standard Prelude from Programming Praxis. Using these procedures helps to keep code terse and reduce the need for ad hoc lambdas.

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 Guile modules to access the REST API of Mastodon, a federated microblogging service.

Guile JsonLD is an implementation of the JsonLD (Json for Linked Data) API defined by the W3C for GNU Guile. It allows you to express links between data, in a way that is very similar to WikiData or RDF for instance. An object can have relations (in the form of an IRI) that relates it to one or more objects or strings, represented by a Json object or an IRI.

Veritas is a testing framework for Guile with an EDSL to define test suites. Emphasis is placed on legibility and maintainability of tests. Veritas shuffles tests and runs them concurrently by default to ensure robust testing practices.
