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.

The Concise Binary Object Representation (CBOR), as specified by RFC 8949, is a binary data serialization format. CBOR is similar to JSON but serializes to binary which is smaller and faster to generate and parse. This package provides a Guile implementation of CBOR.

This is an R6RS Scheme adaptation of the packrat parsing. Packrat parsing is a memoizing, backtracking, recursive-descent parsing technique that runs in time and space linear in the size of the input text.

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.

R7RS-small Scheme library for reading and writing RSV data format, a very simple binary format for storing tables of strings. It is a competitor for CSV (Comma Separated Values) and TSV (Tab Separated Values). Its main benefit is that the strings are represented as Unicode encoded as UTF-8, and the value and row separators are byte values that are never used in UTF-8, so the strings do not need any error prone escaping and thus can be written and read verbatim.

The RSV format is specified in https://github.com/Stenway/RSV-Specification.

Scriba is a structured logging library for GNU Guile that prioritizes flexibility and observability. It provides modular log routing, formatting, and filtering, allowing developers to generate human-readable console logs during development and machine-readable JSON logs for production environments. Key features include an auto-logger configured via environment variables, dynamically scoped log contexts using Scheme parameters, ahead-of-time log level filtering, and minimal runtime overhead achieved through memoization and compile-time macros.

Guile Shapefile is a Guile library for reading shapefiles.

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.

This Guile library provides tools for reading, comparing, and writing Semantic Versions. It also includes ranges in the style of the Node Package Manager (NPM).

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

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.

This project is about the development of tools that relate to machine code and object formats; for all architectures. Here you'll find libraries for working with binary code: assembly, disassembly, instruction tables, object formats and related areas.

Emacsy is an embeddable Emacs-like library that uses GNU Guile as extension language. Emacsy can give a C program an Emacsy feel with keymaps, minibuffer, recordable macros, history, tab completion, major and minor modes, etc., and can also be used as a pure Guile library. It comes with a simple counter example using FreeGLUT and browser examples in C using Gtk+-3 and WebKitGtk.

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.

See http://minikanren.org/ for more on miniKanren generally.

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.

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.

Gulie-CoAP is a Guile implementation of the Constrained Application Protocol (CoAP). CoAP is a network transport protocol specialized for use with constrained nodes and constrained networks (e.g. low-power, lousy). This library implements basic serialization of CoAP messages over UDP (RFC 7252) and TCP (RFC 8323) as well as an asynchronous TCP client (using guile-fibers).

This tiny package provides some procedures and macros to extend Guile Scheme procedure composition facilities. For example, there is a compose-top, a reverse-order analog to native compose procedure. The compose-cont is a macro, utilizing some power of continuations to build really flexible flows.

This library is intended to stay basic and small, so it has no any external dependencies and can be a good base for other packages, like e.g. guile-web-middleware.

Guile-syntax-highlight is a general-purpose syntax highlighting library for GNU Guile. It can parse code written in various programming languages into a simple s-expression that can be converted to HTML (via SXML) or any other format for rendering.

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 package provides a Guile Scheme wrapper for libgsl.so. Implements

• GSL vectors.

• Matrices.

• BLAS operations.

• Eigensystem solutions.

• One-dimensional root solvers.

guile-jwt is a JSON Web Token module for Guile. JSON Web Tokens are an open, industry standard (RFC 7519) method for representing claims securely between two parties. guile-jwt allows you to decode, verify and generate JWT. Supported algorithms: HS256, HS384, HS512.

This package provides Guile bindings for the libmosquitto MQTT client library. The bindings are written in GOOPS, and the user can extend the client class by inheritance.
