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.

A module for GNU Guile to read and write YAML files. It works using bindings to the yaml-cpp C++ library.

guile-aspell is a Guile Scheme library for comparing a string against a dictionary and suggesting spelling corrections.

Wisp is a syntax for Guile which provides a Python-like whitespace-significant language. It may be easier on the eyes for some users and in some situations.

This package provides tooling to write web applications in Guile, such as signed sessions, multipart message support, etc.

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.

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.

guile-newra (newra) wants to replace the current (3.0) Guile array system, which is almost entirely implemented in C. The new implementation should be at least as fast.

guile-goblins is the Guile version of Spritely Goblins, a transactional, distributed programming environment following object capability security designs. Goblins is a general toolkit, and also the core layer of Spritely's work to support healthy distributed networked communities. Goblins allows for cooperation between networked programs in a mutually suspicious network through OCapN, the Object Capability Network. This includes collaboration across runtimes; for instance, programs written in the Guile and Racket versions of Goblins are able to speak to each other.

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.

Fortran is great in expressing operations on multi-dimensional arrays of numbers. Scheme is great at expressing your coding thoughts. This project is an attempt to combine both into something useful.

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-filesystem provides a set of utility functions, that augment Guile's support for handling files and their names.

This package provides a functional parser combinator library that supports backtracking and a small logical framework. The idea is to build up chunks that are memoized and there is no clear scanner/parser separation, chunks can be expressions as well as simple tokens.

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).

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-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.

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.

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

This library implements a JavaScript Object Notation (JSON) parser and printer. It also supports parsing JSON objects that may be bigger than memory with a streaming API.

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.

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

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).
