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

G-Wrap is a tool and Guile library for generating function wrappers for inter-language calls. It currently only supports generating Guile wrappers for C functions. Given a definition of the types and prototypes for a given C interface, G-Wrap will automatically generate the C code that provides access to that interface and its types from the Scheme level.

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.

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.

This package provides A Guile reader extension for `raw strings', it lets you write verbatim strings without having to escape double quotes.

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).

This package provides Guile bindings to the libsodium cryptographic library which provides core cryptographic primitives needed to build higher-level tools.

guile-xapian provides Guile bindings for Xapian, a search engine library. Xapian is a highly adaptable toolkit which allows developers to easily add advanced indexing and search facilities to their own applications. It has built-in support for several families of weighting models and also supports a rich set of boolean query operators.

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 collection of iteration macros for Guile. They are inspired by racket's family of iterators. Specifically, the following iterators are available:

• for

• for/map

• for/c

• for/fold

• for/fold-right

• for/folder

• folder

guile-custom-port overrides Guile's port modules to bring the custom ports from Guile 3.10 to previous versions.

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

This package provides a Scheme wrapper around liblmdb.so. Most names are the same as LMDB ones, except for prefix absence. Several conveniences are added on top:

• call-with-env-and-txn, call-with-cursor, and call-with-wrapped-cursor helpers and respective with- macros.

• for-cursor procedure for cursor iteration.

• val and stat types.

• set-compare! and set-dupsort! to configure entry sorting.

• Error signaling instead of integer return values.

Guile-JPEG is a Scheme library to parse JPEG image files and to perform geometrical transforms on JPEG images.

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.

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-Quickcheck is a library for random testing of program properties inspired by ghc-quickcheck. You can use it to express properties, which functions should satisfy, as Scheme code and then check whether they hold in a large number of randomly generated test cases.

This package provides a procedure for converting strings into URL-friendly slugs. A slug is a simplified version of a string, often used in URLs, that contains only lowercase letters, digits, and hyphens. This package is inspired by the slugify function in the Django web framework. It is useful for generating human-readable identifiers from arbitrary text.

guile-dbi is a library for Guile that provides a convenient interface to SQL databases. This package implements the interface for PostgreSQL.

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 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.

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 library provides a reference implementation for SRFI-223. This SRFI defines a generalized procedures for binary search of vector-like data structures are provided which can be applied to any sequence type, including ones defined by the user, together with applications of these procedures for Scheme’s built-in vectors.
